Nocebo: The Power of Negative Thinking?

2011-02-27T12:45:00.000-07:00

Doctors Need to Appreciate the Effects of Prescribing and Describing Therapy

Maybe it's the power of marketing. Maybe it's faith in our doctors. Or maybe the physical effects of what we believe are more powerful than we like to think. In any event, new data indicate that how doctors describe what they give us may effect us in powerfully positive or negative ways.

It's a Sham
Placebos, and their lesser known counterparts nocebos, are sham treatments. The difference is in the response to the therapy. Placebo, from Latin meaning “I will please” is often delivered in a manner that leads the patient to expect a positive effect. Nocebo, meaning “I will harm,” is associated with negative responses to inactive therapy.

In a study reported today (http://bit.ly/gec3tz), people's pain levels fluctuated greatly based on what they were told about a pain medicine they had been given, including an increase in pain when told they were no longer being given the drug – when in fact they were still receiving it. (The nocebo effect.) So, patient belief was a strong indicator of whether the drug worked or not, even though the dose of the drug did not change throughout the experiment.

Nocebo effects can be enhanced, too, with warnings the therapy will likely produce negative effects. In other words, a placebo “sugar pill” is given to patients who are led to believe that the pill will provide pain relief; the nocebo effect is enhanced with a warning that the pill will likely cause adverse effects, such as nausea.

However, the doctor does not have to say anything for the nocebo effect to kick in. Patient beliefs may be established long before he or she shows up at a doctor's office. In Science Translational Medicine, researchers suggest that doctors may need to consider dealing with patients' beliefs about the effectiveness of any treatment, as well as determining which drug might be the best for that patient. For example, people with chronic pain will often have seen many doctors and tried many drugs that haven't worked for them. Professor Irene Tracey at Oxford University, said, “They come to see the clinician with all this negative experience, not expecting to receive anything that will work for them. Doctors have almost got to work on that first before any drug will have an effect on their pain.”

All science needs a mechanism of some kind, so what is behind these powerful placebo and nocebo effects? It’s not clear, but the evidence does suggest that it’s not all psychological. Physiologically, there appears to be an endorphin release in the brain that accompanies a placebo response. Placebos given to people who are told they are pain killers will actually elicit analgesic effects via both drug-related (neuropharmacological) and neurologic (neuroanatomical) avenues. In other words, the body’s response is similar to what one would expect from actual medicine despite the fact that the sugar pill given contains no medication.

Additionally, placebos commonly elicit beneficial therapeutic responses in anxiety and depressive disorders. The psychological behaviorism theory considers the placebo a stimulus conditioned to elicit a positive emotional response. Some research suggests that pain sensitivity and pain anxiety increase susceptibility to placebo effects.

Stunning Effects
While not as commonly known as placebos, nocebo effects can be stunning. For example, in one study, patients were told they were receiving either a relaxant, a stimulant, or an inactive agent; in point of fact, all patients received the inactive agent. Patients told they were getting a relaxant showed reduced stress levels, while those who thought they were getting a stimulant showed increased arousal levels.

With the heart pain known as angina, for example, sham surgeries work in up to 70% to 80% of patients who show clinical improvement great enough to increase the key measures of heart function (known as functional class). Similar data are also are seen in heart failure patients who show improvement in functional class or, at the very least, significant improvement in quality of life.

Placebo drug therapy isn’t quite as “effective” as that sham surgery was, but it still is quite common. In a study by Italian investigators, 600 patients with histories of drug side effects were given inactive placebos and more than 1 in 4 showed “drug” side effects. The nocebo response was significantly higher in women than in men. So, the nocebo effect occurs frequently in clinical practice. In clinical trials, too; it’s rare that a placebo will elicit significantly more side effects than the comparison drug therapy, but it is not uncommon that in sheer numbers more stomach upset is reported with the placebo, despite the fact there should be NOTHING in the inert agent to cause stomach upset.

By the way, even mechanical devices can show placebo/nocebo effects. In a study called VPS II, pacemakers were implanted in patients but only half were activated; the rest were in monitoring mode and collecting information but not actually pacing the heart. Despite the fact half were turned off, both groups showed similar improvements.

Finally, it’s not just the words and manner of the doctor that can influence the effects of placebos. Evidence suggests you can literally build a better placebo by taking into account size, color, shape, and “brand” of the sugar pill!

With doctors using more and more technology while spending less and less time with patients, it’s important that doctors appreciate the power of prescribing and describing a therapy – whether it’s a real therapy or a perceived therapy.

Teens Think They’ll Live Forever, Which May Explain Their Food Choices

2010-11-15T13:32:00.000-07:00

Teens just can’t catch a break in the health department.

Last week we learned, if nothing changes, today's obese kids will have heart attacks much earlier than their parents. http://bit.ly/9R3647 It’s because of the epidemic of obesity seen in children and adolescents today. As a result, if we are not successful and the obesity problem remains or – heaven help us – gets worse, our kids today will start having heart attacks by the time they hit their 30s and 40s.

Also, last week, we learned that excess stress during adolescence may be setting young people up for more mood disorders as adults. http://bit.ly/azJOrI If there is one thing more universal among young people today than obesity, it’s stress. So, that’s just great news! And we learned that kids with hypertension have more learning disabilities. http://bit.ly/cKX6PP Since obesity is tightly tied to the development of high blood pressure – well, you can see the problem.

Is There Any Good News?

Here at the American Heart Association meeting, investigators reported that maintaining a healthy lifestyle from young adulthood to middle age plays a huge role in achieving a low cardiovascular disease risk profile in middle age.

In other words, the solution to the more-heart-attacks-sooner problem of tomorrow is helping young people make more heart healthy choices today.

Here’s the data: Researchers studied the long-term follow-up of the Coronary Artery Risk Development in Young Adults (CARDIA) study. Researchers wanted to know whether adopting a healthy lifestyle from young adulthood to middle age can lead to a low cardiovascular disease risk profile in middle age – we already know that your risk factors in middle age play a big role in how healthy or unhealthy your cardiovascular system is years later.

CARDIA included 2,498 black and white participants 18 to 30 years old in 1985 at baseline. Compared to their peers, a healthy lifestyle was one that included:
• Not being overweight or obese
• Having no or only moderate alcohol intake
• Eating a diet with more potassium, calcium and fiber
• A lower intake of saturated fat
• Being more physically active
• And never smoking cigarettes.

After 20 years, more than 60% percent of people with all five healthy lifestyle factors from young adulthood to middle age showed a much lower risk profile compared to the less than 6% of people with none of the healthy lifestyle factors.

In this study, risk profile was based on common factors that influence your heart health: blood cholesterol, blood pressure, smoking, diabetes and history of heart attack. That means, for young people who had healthier lifestyles, they were less likely to later have major risk factors like high blood pressure, high cholesterol, etc.

We know that middle-aged adults with fewer cardiovascular disease risk factors have a longer life expectancy, dramatically lower rates of heart disease, better quality of life, and lower health care costs as they age. The same would appear to true of young people, too.

More good news: overall, even in this age of obesity, the majority of young adults have a low cardiovascular risk profile; they don’t have hypertension, they don’t have high cholesterol levels, etc. The majority! Only about 7% of American middle-aged men and women satisfy the low cardiovascular disease risk profile.

So, young people are starting out way ahead of their parents – but they’ll lose that advantage quickly if they don’t change some of their lifestyle habits.

Bottom line: More emphasis should be devoted to encouraging healthy lifestyles among young adults.

Not sure how to talk to kids about food? Last week I noted the fine line between obesity and eating disorders. At the time, I recommended this post, from Psychology Today, on talking to kids about eating, food, and weight. http://bit.ly/9mPKby

Forget You Even Know the Word Exercise: Choose to Move

2010-11-14T14:00:00.000-07:00

Had another great conversation with a world-class medical investigator today, whose specialty is diabetes. Once more, the topic turned to the impossibility of getting middle-aged and older adults to exercise.

Maybe the real problem is the word itself. Exercise brings forth images of weightlifting, jogging, calisthenics. (Cripes, a shudder just went down my spine: I hated PE when I was a kid!)

The American Heart Association has the right idea and they call it: Choose to Move.

Here at the AHA meeting, investigators reported on this national Web-based intervention program. The 3,796 women in the organization’s national 12-week Choose To Move program were provided weekly activity guides and requested to complete surveys on activity, quality of life and readiness for activity.

Researchers evaluated 892 women who completed the program. Participants improved their activity from a median 240 to 343 kcal/week. What does that mean? Glad you asked. In daily conversation, the word calorie is used instead of the more precise scientific term kilocalorie. When a fitness chart says you burn about 100 calories for every mile you jog, it means 100 kilocalories.

So, we burn calories when we are active (notice I did not say the E word) and all these women did was increase the number of calories burned in a week by a little over 100 calories – and their body mass index improved from 29.3 to 28.9 kg/m2 after 12 weeks. Also, they were scored on how much energy they had and their overall well-being; both improved with such a small increase in activity.

Forget jogging; depending on your weight, 100 calories would be about what you would burn in a 20-minute walk. That is do-able for just about anyone!

For more than 2 years now, I walk 2.2 miles with my youngest son (he’s 16) every night. Eric and I are both in much better shape.

There is an old saying, “Use it or lose it.” Don’t think about the E word. Exercise is something we did in school and we either loved it or hated it. Sadly, that became our mental image of exercise and now we think we have no time or energy for that. Or we just think we would look ridiculous in our old gym suits. The trick is to realize that all you need is a different point of view: move it or lose it.

The Eyelids Have It: Your Eyelids May Predict Risk of Heart Attack, Death

2010-11-14T12:40:00.002-07:00

Think of me as a medical version of Lewis Black: When a medical story falls through the cracks, I’m there to catch it. Here’s a story from the American Heart Association meeting in Chicago that should have gotten some attention:

Cholesterol deposits on eyelids, which has the jaw-breaking name of “xanthelasmata,” (say that 3 times fast) predict your risk for heart attack, artery disease and early death.

The Danish team reporting the data say that because half of the people with the deposits have normal blood cholesterol levels, the eyelid lesions may be an important independent marker of underlying artery disease.

Here’s what the study showed:

Copenhagen researchers established the presence or absence of xanthelasmata at baseline in 12,939 people. Of these, 1,903 developed heart attacks, 3,761 developed ischemic heart disease and 8,663 died during up to 33 years of follow-up. Cumulative incidence of ischemic heart disease and heart attack as a function of age increased in those with xanthelasmata, and the proportion surviving decreased.

Xanthelasmata predicted 51% increased risk of heart attack and 40% increased risk of ischemic heart disease. Those with xanthelasmata also had a 17% increased risk of death after adjustments for well-known cardiovascular risk factors including blood cholesterol levels.

OK, here’s the hard science for those who enjoy it: The results suggest that other factors besides cholesterol levels — including capillary leakage, characteristics of macrophages or intercellular matrix components — “may predispose certain individuals to both xanthelasmata and to atherosclerotic disease and early death,” researchers said.

“In societies where other cardiovascular disease risk factors can’t be readily measured, presence of xanthelasmata may be a useful predictor of underlying atherosclerotic disease,” researchers said.

One editorial note: This flies against some earlier data. In 2008, investigators reported no link between xanthelasmata and cardiovascular disease risk. (Read the story here: http://bit.ly/9I1LVU) Granted, it was a much smaller study, so the work from the Danish investigators may be more reliable because of its sheer size.

Doctor, You’re Getting on My Nerves

2010-05-09T12:44:00.002-07:00

Make sure it’s a nurse who takes your blood pressure!

A recent study in the British Medical Journal reported that blood pressure recorded by doctors was higher than that recorded by other health professionals. It was a big difference: 9 mm Hg systolic (the first number commonly given when reporting blood pressure) and 7 mm Hg diastolic. It’s not that doctors don’t know how to take blood pressure readings! Due to an affect called white coat hypertension, blood pressure measured in the clinic by doctors tends to be higher than that measured by nurses.

Is the lower blood pressure actually the correct blood pressure? A large study by La Batide-Alanore and colleagues (Journal of Hypertension) showed a similar difference between blood pressure readings made by doctors and nurses, with the added finding that the nurse recorded blood pressure was closer to the patient’s daytime average blood pressure (so-called ambulatory blood pressure) than the pressure recorded by the doctor.

That’s what the new BMJ study found, too: daily blood pressure readings outside of the clinic were very similar to what the nursing staff recorded in clinic. The new study also adds to our knowledge by finding two exceptions: Ambulatory blood pressure readings tended to be slightly lower for women than for men and lower in older people (>65 years) than in younger people. Also, the difference was similar whether the people studied were already on blood pressure medicines or not.

For a number of reasons, we seem to choke up a little in the presence of doctors. We're nervous about what they may tell us. Maybe we feel they're rushed and we feel rushed, too. Whatever the reasons, there is one thing for sure: Have confidence when a nurse takes your blood pressure. And, doc: Don’t take it personally.

(By the way, the British Medical Journal allows free access to research studies. If you want to read the full study, here's a shortened link: http://bit.ly/dswIbW .)

Nobel Prize Winner Sir James W. Black (1924-2010)

2010-03-27T20:34:00.005-07:00

Whether you know it or not, you have benefited greatly by the work of this man who passed away this week.

It is extraordinary to create a new drug that is the first of its kind; Sir James W. Black, MD did it not once but twice. If you have ever taken a beta-blocker (like atenolol, propranolol, or carvedilol) or an over-the-counter heartburn remedy (such as Zantac or Pepcid) you are indebted to Dr. Black. If you have never required either class of drugs, you still owe a great deal of gratitude to this scientist.

I have interviewed several Nobel Prize winners through the years, with the first being Dr. Black. What a place to start! His work helped take medicine to a new place that continues to produce life-saving drugs.

A Whole New World
Early drug development was based on chemical modification of natural substances. For example, early Greeks used willow bark as a fever fighter. Today we know it as aspirin. Another mainstay of medicine came from a beautiful country garden flower called foxglove; in 1775, an old woman’s home cure was first recognized as containing a powerful heart medication called digitalis.

Sir James W. Black, MD was one of the pioneers who introduced a more rational approach to drug development based on understanding basic biochemical and physiological processes. Instead of synthesizing drugs from naturally-occurring compounds, Dr. Black and others looked to purposefully build drug molecules that would directly interact with cells and cellular processes throughout the body.

Here’s just one example of how this works. Epinephrine and norepinephrine have opposing effects in the body. In 1948, American scientist Dr. Raymond Ahlqvist suggested these opposing effects were mediated by different receptors in the target organs. He called these different receptors alpha- and beta-receptors, suggesting that substances could selectively stimulate these receptors (agonists) or inhibit these receptors (antagonists). It was this theory that inspired Dr. Black and his colleagues.

A Nobel Life
Like many Nobel Laureates, Dr. Black’s personal story was colorful. In describing his education, this Scottish doctor admitted he “coasted, daydreaming, through most of my school years.” At 15, a math teacher “more or less man-handled me into sitting the competitive entrance examination for St Andrews University.” The fourth of five children from a staunch Baptist family, there was no money to send another kid to university, but that did not matter when his test scores led him to a full scholarship.

After earning his doctorate, he decided against a career as a medical practitioner due to what he perceived as the insensitive treatment of patients at the time. (To understand just how uninspiring medicine was back then, read my posting on the $14 Billion Heart Attack here: http://bit.ly/5PEh2j.) Instead, he joined the University of Glasgow in their veterinary school, eventually establishing the school’s physiology department.

He developed an interest in the way adrenaline affects the human heart, particularly those suffering from the often crippling chest pain known as angina. He had a theory to annul the effects of adrenaline, so he joined ICI Pharmaceuticals in 1958, where he created the first beta-blocker, propranolol. The discovery of this drug was hailed as the greatest breakthrough in the treatment of heart disease since the discovery of digitalis two centuries earlier.

He saw that the general idea might be applied to treat stomach ulcers, but his employers weren’t interested. So, Dr. Black left ICI in 1964 and joined Smith, Kline and French. (After numerous acquisitions and mergers, the company is known today as GlaxoSmithKline.) There, in 1975, he developed cimetidine (sold as Tagamet) which became the best-selling drug in the world. The drug that Tagamet knocked out of the #1 slot for worldwide sales: propranolol.

Based on this pivotal research, Dr. Black shared the 1988 Nobel Prize in Physiology or Medicine with Gertrude B. Elion and George H. Hitchings for their discoveries of “important principles in drug treatment.”

Of all the things Dr. Black and I discussed 10 years ago, this stands out:

He met his wife, Hilary, when they were both students at St. Andrews University. Upon graduation, Dr. Black stayed there as a teacher while his wife completed her degree in biochemistry. Dr. Black called his wife “the best student I ever had.” Her eclectic pursuit of knowledge led her to study law and later poetry.

Calling her "the mainspring of my life" until she died in 1986, he said, “Intellectually, she was the most exciting person I have ever known.”

Dr. Black, many could say the same about you.

2001: A Medical Odyssey

2010-03-06T14:04:00.001-07:00

How Did Experts Do in Predicting What Medicine Would Look Like Today?

In 1987, 227 world-class scientists were asked to predict the state of medicine in the 21st Century. This was no simple survey: the full report was 203 pages of statistics and analysis, commissioned by Bristol-Myers and conducted by Louis Harris and Associates,

When I originally wrote about the predictions, my work was front-page news in medical and lay news outlets. Now, the future is here: how did the experts do?

• They predicted a 67% cancer cure rate: Pretty much right on target. Today, the 5-year survival rate for cancer overall is 66%. (The comparable cure rate when the experts made their prediction: 54%.)

• No more heart bypass: Missed it by a mile. Specifically, cardiovascular scientists predicted most of the 230,000 heart bypass surgeries being done in 1987 would be replaced by less invasive procedures. Well, there are now 1.3 million such minimally invasive heart interventions done each year; but far from being replaced, nearly twice as many heart bypass procedures are being done each year in the US today (448,000) compared to 1987. It’s partly a factor of an aging population, but mostly it’s a realization that specific types of patients still do better with open surgery.

• 61% predicted an AIDS vaccine by the year 2000: Way too optimistic. Later this year, experts will gather for the 10th annual AIDS Vaccine Conference. In their preliminary program, the chairs of the conference state that despite “encouraging progress…we remain a long way from an affordable, effective vaccine against HIV.”

• A majority predicted an AIDS cure by 2010. Nope. (To be fair, 73% of the infectious disease experts surveyed in 1987 were at complete odds with most of the other experts and saw little or no improvement in treating AIDS by 2000.)

• The death of traditional psychoanalysis. Saw this one coming and, not surprisingly, the central nervous system experts who predicted this were way over-confident. (The word cocky also comes to mind.) Granted, the percentage of patients who receive psychotherapy is about 28.9% today compared to 44.4% in 1996-97. Still, that’s far from “little or no role” for psychotherapy. Importantly, there’s one big reason for the downturn in psychotherapy: financial incentives (insurance reimbursement) favor short medication visits compared with longer psychotherapy sessions. However, given growing concern regarding the widespread use of psychotropic drugs coupled with recent research showing the benefits of cognitive therapy, reports of the death of psychotherapy are greatly exaggerated.

• The “Golden Age of Biology.” Dr. Leroy Hood, whose work revolutionized genetic engineering and biology, said, “I think we will develop every bit as revolutionary technologies in the next 10 years as we have in the past 10 years.” Frankly, if the survey were repeated today, I suspect many of our current world-class scientists would agree and say the same thing about the next 10 years in medicine.

Finally, the experts in 1987 were nearly unanimous on one point: that disease-prevention would do more than advances in either treatment or diagnosis. For example, while steady improvement was predicted for “curing cancer,” there was almost complete agreement that a smokeless society would be the most effective strategy in the prevention and treatment of lung cancer.

25 Years Ago, Kids Were Fitness Failures; It 's Only Gotten Worse

2010-03-05T00:34:00.003-07:00

Overwhelming Evidence Heart Disease Starts in Childhood

In September 1985, I wrote: “In the middle of a wellness boom, our children’s fitness is a bust.” Twenty-five years ago, in an age of 10K runs, aerobic fitness centers, and Jane Fonda workout videos, our kids were physical wrecks. Since then, things have deteriorated to a point where some might think of the 1980s as “the good ol’ days.”

Today’s kids may be the first generation to have a shorter lifespan than their parents, but parents can stop the obesity epidemic. http://bit.ly/17KfEK Here are some ideas and links to more information.

• Getting young kids to eat better is not as hard as you think. That’s because the biggest influence on their eating habits is mom and dad. As I explained some time ago, if you want your kids to eat better – especially younger kids – then buy better foods. http://bit.ly/7rDkdd Just today, I reminded a friend who wants to lose weight that the easiest way to avoid junk food is to not buy it!

• Consider the French Paradox. Research scientists have been puzzling for years over why the French eat more fat than Americans yet have a lower incidence of heart disease and a much thinner population. This explains a lot: there is a huge difference between what French and American children eat for lunch at their schools. Similarly, there is a big difference in what French and US parents teach kids about food. http://bit.ly/d4emHj

• Are kids fat because we’ve taken the fun out of fitness? Experts think there is too much focus on sports and not enough on just moving. http://bit.ly/8N59ne It doesn’t take a lot. For almost 2 years now my youngest son and I have walked about half an hour every day. It’s great fun for us and both of us have lost weight.

• Studies conducted over the last several decades provide overwhelming evidence that heart disease often starts in childhood. Fortunately, even without weight loss, kids who exercise show a big reduction in markers associated with a greater risk of heart disease. http://bit.ly/570QzE

• Do you eat when stressed? Guess what: Kids often have the same response. Sadly, many parents are blissfully unaware just how stressed out their kids are today. http://bit.ly/4EhLDH And, frankly, all work and no play makes kids more than dull; it’s why they're so anxious and depressed. http://bit.ly/6Tx829

• If kids have a weight problem, it’s a family problem. You won’t have a lot of authority if you tell your child he needs to lose weight when you’ve just opened a sack of potato chips. Think extended family, too: Youngsters are more apt to be fat with regular grandparent care. http://bit.ly/bDdCZT Clearly, grandma and grandpa need to up their babysitting game.

This isn’t rocket science, although you might think so given our complete failure at addressing these issues. It requires paying attention, avoiding mixed messages, and making better nutrition and more activity priorities.

Killer Salt has been Given More than a Fair Shake

2010-03-04T13:32:00.007-07:00

Food Giant Knew It was Using Weak Research to Confuse the Public

People who should know better are warning of the coming war on salt. They are deriding efforts to curb our consumption of this vital but wildly overused mineral.

The source of their “war” propaganda was a recent paper in the New England Journal of Medicine. The authors estimated that cutting daily salt intake by 3 grams (less than a teaspoon), would dramatically improve health in the United States, including a huge impact on stroke and heart disease deaths. http://bit.ly/4sh1xu Indeed, if we could curb our salt habit, experts say we would prevent about half a million strokes, another 500,000 heart attacks, and save some $32.1 billion in medical costs over the lifetime of adults ages 40 to 85. http://bit.ly/ausqjY

So, what’s the confusion? In a word: marketing.

Earlier in my career, a bright Oregon scientist claimed to have discovered that a lack of calcium and not an excess of sodium was linked to hypertension. I know this because I covered the story for many of the consumer and physician publications I worked for at the time.

Shortly thereafter, another scientist who had an insider’s point of view let me know I had been duped. (Me and a thousand other reporters.) Turned out I was talking with a researcher whose office had funded the study, much to his dismay. The doctor who did the calcium research had turned to one of the largest manufacturers of salty snack foods for investigational support (money). In an interoffice memo, the corporate director of research and development questioned the investigator’s “weak” results, but recommended funding his work.

Why? He stated that the data would confuse the public and “release the pressure on sodium for the time being.” Moreover, he noted that the controversy over salt would return, but the study would provide a break from the nonstop negative press being given to high-sodium-content foods. The memo even went so far as to suggest that since the researcher’s scientific credentials were weak the company should provide him “with scientific assistance to enhance his credibility and promote visibility.” (Note: his emphasis, not mine.)

The memo also suggested releasing the data during a time when most leading heart doctors in the U.S. would be out of the country attending an international cardiology meeting. The memo noted that this would give the calcium story several days of media attention before any medical authority could get caught up with the news and caution against the findings of the calcium study.

I am not naming the researcher since I doubt he was privy to the in-house intrigue that was the determining factor behind his funding. But I offer this as a cautionary tale. We saw this once before with the tobacco industry doing everything in its power to support really bad science that very effectively confused the public. Clearly, some within the food industry were taking notes.

The “Obesity Paradox” Suggests Many of Us Need to be a Little Less Weight Obsessed

2010-02-26T10:26:00.004-07:00

Could we be getting to the point where your doctor says you’re definitely obese and that’s just fine?

Maybe and, if we do, it will be because of the “obesity paradox.” In brief, growing evidence suggests all of us should take a deep breath and chill a little over older adults who are overweight or a little obese. Not morbidly obese – which is a medical term, by the way, and not an editorial comment – but rather a specific weight classification technically known as obese (or category 1 obesity). That’s because once obese people develop heart disease, they live longer than those who are thin (what has previously been considered normal or even optimal weight - See "me"). Plus, they live longer than those who are morbidly or super obese (again, that’s medical terminology, not editorializing).

I was reminded of this recently while listening to results of the largest clinical trial of people with heart failure and preserved ejection fraction. Ejection fraction is that small portion of blood pumped out of the heart with each heart beat. About half of all people with heart failure have a fairly normal or “preserved” ejection fraction. Like many studies in the last few years, when the I-PRESERVE trial data were analyzed to determine the effect of obesity on outcomes like death or hospitalization, the best results were seen among those people who were obese. The worst outcomes were seen in the thinnest and the fattest groups of individuals.

The stylishly thin Dr. Markus Haass of Theresien Hospital Mannheim, Germany, finished his presentation in November at the 2009 American Heart Association meeting by saying, “If I ever develop heart failure, I had better gain some weight.” In taking questions from the audience, a San Francisco doctor stood up, acknowledged his own obesity, and admitted “I really like these results.” The audience laughed and he added, “This is more evidence that the definition of normal body weight may be set too low.”

Just What is Normal?
Doctors use body mass index or BMI as an important measure of body fat. What is your BMI? All you need to know is your height and weight, then use a calculator like the one here to determine your BMI: http://www.nhlbisupport.com/bmi/

These are the categories used to define weight:
• Underweight = <18.5
• Normal weight = 18.5-24.9
• Overweight = 25-29.9
• Obesity = BMI of 30 or greater

In recent years, doctors have refined the category of obesity even further to include:
• Any BMI ≥ 35 or 40 is severe obesity
• A BMI of ≥ 35 or 40–44.9 or 49.9 is morbid obesity
• A BMI of ≥ 45 or 50 is super obese

A Little History
In 2002, a study of nearly 10,000 patients surprised a lot of people. Investigators looked at patients undergoing a common heart procedure called angioplasty and evaluated the results based on BMI. While the procedure was equally successful in all the weight groupings studied, normal BMI patients had a higher incidence of major in-hospital complications, including cardiac death and this difference was statistically highly significant (p = 0.001). After 1 year, more people with normal BMI had died compared with overweight or obese patients (p < 0.0001).

The study raised a few eyebrows, but because the results were so different than what was expected, it was largely dismissed as a likely anomaly. Then in 2005 (after more reports of such “anomalies”) Katherine Flegal, PhD, who is a senior researcher at the Centers for Disease Control (CDC), published a paper in JAMA that concluded that overweight and obesity accounted for far fewer deaths than thought. Specifically, instead of the 365,000 deaths in 2000 (the CDC’s own numbers) her study estimated that only 112,000 deaths in the US that year were associated with obesity (BMI of 30 or higher).

Dr. Flegal also found that people who were overweight but not obese (BMI of 25 to less than 30) were less likely to die during follow-up than normal weight individuals (BMI of 18.5 to less than 25). The greatest risk of death was among the leanest (BMI <18.5) and among the most obese (BMI of 35 or higher.) In other words, as you get older, it’s looking like being a little bit chubby is actually protective against death.

He Said What?
Back to the presentation I talked about earlier. After the audience member said he and his waistline were relieved and encouraged by the results, Dr. Haass who presented the I-PRESERVE data said: “It is better if you are young and have no major chronic disease to be a little on the lean side but once you develop heart failure or have a (heart attack) you better have a little so-called overweight because this is prognostically an advantage.”

Think about that statement: Once you have a heart attack or develop heart failure, you need some excess weight. Can you imagine your doctor saying, “Well, you’ve had a heart attack, so I’m giving you a special diet because you need to put on a few pounds.” As you might imagine, there are a number of doctors who are nearly going ballistic over data that even hints at such a recommendation.

Yet, if you have a BMI that makes you overweight or a little obese, maybe your doctor should not have you worry too much about weight loss. Certainly, once you have had a heart attack or have developed heart failure, you have plenty of other things to worry about, but maybe your weight shouldn’t be one of them – unless, of course, you have a BMI of 35 or higher, where all the data suggests you need to lose some weight.

There have been a total of 84 papers published since that first article in 2002 referred to this “obesity paradox,” which isn’t nearly enough data to bring an end to the debate. (I suspect it’s just getting going. Medicine moves slowly, sometimes even glacially.) But perhaps we need to stop obsessing so much about gaining a few pounds as we age, because if there is one thing pretty obvious from decades-worth of data it’s how massively unhealthy yo-yo dieting is. This never-ending loop of weight loss and weight gain is absolutely not healthy for anyone. So, you’re older and a little overweight? Frankly, that’s probably just fine.

The $14 Billion Heart Attack

2010-01-03T00:39:00.001-07:00

Sometimes we don't know how far we've come until we look back at where we’ve been. Once a heart attack was a likely death sentence; if you survived, you were often crippled for life – oddly enough, sometimes due as much to the “therapy” of the time than the heart attack itself.

Three leading heart specialists recently discussed how the heart attack has been tamed as they reviewed the past, present, and future of cardiac care. http://bit.ly/6KTaQr However, my favorite example of just how far we’ve come is the story of a former President. I first heard this from Dr. William W. O'Neill of the University of Miami, Florida, and I am now adding additional details here.

In 1949, General Dwight Eisenhower had finished conquering Europe, beaten the Nazi Empire, and become one of the most recognized people in the world. He was a heavy smoker and that year he started having chest pain. His doctor told him to quit smoking and the general successfully lowered his cholesterol. The changes seemed to work; he was healthy enough in 1952 to seek and win the Presidency of the United States. Then in late September, 1955, President Eisenhower complained of chest pain on the 9th hole during an afternoon of golf. At that point, he thought he had just eaten too many onions on his hamburger at lunchtime.

He was staying with his mother-in-law in Denver and shortly after midnight, he woke up with severe chest pain. He asked his wife, Mamie, for milk of magnesia, but she was concerned enough to call his personal physician, who arrived around 2 a.m. President Eisenhower had a history of diverticulitis, a fairly common and sometimes painful digestive system problem. So, Dr. Howard Snyder concluded his patient’s symptoms were most likely due to upper gastric pain.

At about 3:00 in the morning, however, the President took a turn for the worse; he became ashy, sweated profusely, and for about 10 minutes Dr. Snyder couldn’t feel a pulse. He improved a little, but by 7:00 AM a call was placed to Fitzsimmons Army Hospital requesting an electrocardiogram. Today, this common test is easily administered and the ECG unit can be wheeled around a room using one hand; but, back then, it was so big that it had to be delivered on a truck. The ECG showed that the President had suffered a large heart attack.

Vice President Richard Nixon decided to call in a civilian heart specialist "because we cannot overlook the fact that many people in the country might have more confidence, however unfounded, in a civilian specialist of national reputation." There was consensus to consult Dr. Paul Dudley White of Massachusetts General Hospital in Boston, arguably one of America's foremost cardiologists. The heart attack led to President Eisenhower being hospitalized from August until mid-October.

(As an aside, on Monday morning, just 2 days after the President’s heart attack, Wall Street panicked and stock prices went into a tailspin. By the end of the day, the Dow Jones had dropped by 6% — a paper loss of $14 billion, the largest decline since the crash of 1929 and one that would exceed those following the assassination of President John F. Kennedy and the shooting of President Ronald Reagan.)

In the mid-1950s, the treatment of MI was 12 weeks of bed rest followed, hopefully, by recuperation. Unfortunately, 25-30% of people suffering such a heart attack died back then. One reason may have been the 12-weeks of hospitalization! Today, we know it is best to get people up quickly after a heart attack rather than let them lie in bed becoming more out-of-shape with each passing week. President Eisenhower survived the initial heart attack, including his long period of bed rest! -- but subsequently died in 1965 having been hospitalized at Walter Reed Hospital for months due to recurrent ventricular fibrillation and angina.

Today, President Eisenhower’s problem would have been fixed promptly, either with angioplasty or surgery, and he would have been in the hospital for 2 days. That is a clear example of where we've been with the treatment of heart attack compared to where we are today.

Food Fight! Nope, not necessary. Getting kids to eat better.

2010-01-01T11:57:00.000-07:00

The tranquil image of mom, dad, and the kids around the dinner table shares a reality with portraits of unicorns and dragons: Fun to look at but still fiction.

At least that’s a common experience of young parents. In re-reading a Los Angeles Times article recently, I had forgotten that one of the paper’s feature writers referred to one youngster as “a miracle child” for preferring vegetables – including mushrooms and beets – to junk food.

As an expert on that kid – he’s my oldest son, Aaron – the lessons from this nearly 20-year-old article written by the Times Kathleen Doheny are just as applicable today as they were when she first interviewed me.

Our kids were raised vegetarian. (Lacto-ovo vegetarian specifically, meaning we ate dairy and egg products.) Still, I do recall telling the reporter about my son, Aaron: "It's a somewhat surreal experience to be in the grocery store and the things he is grabbing are not Ding-Dongs and Hostess Twinkies, but apples. If you say `cake,' his face will light up like a Christmas tree, but he only takes one or two bites and he's finished."

A miracle child? Hardly. The article noted that my wife and I were careful about what food we had in the house. A box of cookies was about as dangerous as it got.
As quoted: "I have to wonder if parents accidentally undermine their own goals by giving the kids access to junk food." After all, "If you don't expose them to it, they don't know it's a choice."

The L.A. Times writer added that we avoided dinner-time hassles with Aaron by not making a big deal over what he eats. "We don't sit down and say, `You must eat everything on your plate,' " McGuire says. "Some days he eats very little, and a few days later it's growth-spurt time and he eats everything."

Support from the Pros

Like all good reporters, Ms. Doheny talked to others, too, for her article “Food Fight! Children Versus Parents Over Veggies.” Elisabeth Schafer, then a professor of human nutrition at Iowa State University, cited flavor as an obvious reason why kids and veggies don't mix.

"Most vegetables tend to have a fairly strong flavor that tastes even stronger to children than it does to adults," she says. That's because kids' sense of taste is more acute than adults'.

Sociology is a factor, too. "Interactions within the family are a very powerful determinant of food aversions," she says. "The children watch what their parents eat. They pick up both verbal and nonverbal cues at mealtimes." The result: If parents don't eat vegetables, it's unlikely the kids will.

I recall the hypocrisy of certain friends and acquaintances who wanted their kids to eat their vegetables, which mom or dad (or both!) actually hated. Also, when around other young parents, I marveled at all the complaints about kids and junk food. Since most toddlers and preschoolers don’t have a lot of disposable income and rarely shop on their own, I wondered how these little rascals were getting their junk food fixes. Oh, yeah, that would be mom or dad.

One other expert endorsed our “easygoing approach” with food. Ellyn Satter, a Madison, Wis., family therapist who specialized in eating problems, wrote the 1987 book "How to Get Your Kids to Eat." She recommended resolving food conflicts by defining zones of responsibility.

"The parent's responsibility is for what, when and where," Satter says. "The child's responsibility is for what and how much."

Translated, that means it's a parent's job to select and prepare healthy foods and determine when and where dinner will be served. It's also up to parents to limit access to snacks and junk foods. Easiest: If it’s not in the house, your kids can’t eat it; at least not during the hours they are home!

Two big pieces of advice not in the article: make desserts occasional treats (or even rare ones) and consider fruit as a side dish.

I grew up in the Midwest where meals almost always involved dessert: pie, cake, ice cream, pudding. (Or combinations, such as pie ala mode!) The “healthy” options were along the lines of fresh berries with whole cream or strawberry shortcake, sometimes with a side of ice cream. I can hear my smaller arteries slamming shut as I write this. With my own kids, desserts were uncommon and almost always separated by hours from the main meal. There is no need for a child to connect “dinner” and “dessert” in the same time/space continuum.

However, I did serve – and still do – fresh fruit with most evening meals. (Yes, I am the family chef and chief grocery shopper.) When many parents think of side dishes for kids, they think of things like mashed potatoes, macaroni and cheese, potato chips, and French fries. Not me: a side is fresh melon, berries, mixed fresh fruits, or an occasional frozen or canned fruit (since fresh peaches are sadly unavailable for most of the year).

Raising a pair of vegetarians was not all that tough. Aaron is a Junior at Duke University and, although I have made it clear that whether he eats meat or not is his own choice now that he is on his own, he still chooses to be a vegetarian. I like to think he was raised right but I know he was fed right.

Cell Therapy and Gene Therapy: You Say You Want a Revolution?

2009-11-25T13:59:00.000-07:00

Finally, a long-promised revolution may be unfolding, based on a series of recent studies. Cell therapy (typically using a patient’s own stem cells) has finally started to show benefit in patients with crippling heart pain (known as angina) who literally have no other treatment option. As for gene therapy, remember the movie “Lorenzo’s Oil?” The disease featured in that story is now responding to gene therapy. In another study, kids have had their sight restored, while a third has used gene therapy to correct a rare immunological disorder.

Like all revolutions, battles are won and lost along the way. The bruising battle for cell-based therapies to treat disease was evident a few years ago when the Journal of the American College of Cardiology published several studies in a special section. One study used patient’s own bone marrow cells to successfully regenerate cardiac tissue from 5 months to 8.5 years after a heart attack. This is long after any intervention is expected to reverse major damage done to heart tissue. Two other studies in the same issue of JACC reported the effects of using two types of widely available growth factor therapies to promote new coronary vascularization. Both studies were stopped early because of ominous results.

Recently, I talked to Dr. Douglas Losordo, Northwestern University Medical School, Chicago. In a randomized trial of “no option” patients with chronic angina, use of patients’ own stem cells plus growth factor therapy led to significant improvements that the patients themselves could recognize. (Sometimes, “significant” benefit is technically achieved but the differences are so small that they are not relevant to the patient’s day-to-day life.)

Dr. Losordo said, “The good news here is that you're talking about a reduction in approximately 14 episodes of angina per week and the patients will tell you, ‘Gee, I can do stuff now that I really couldn't do before.’ It’s really a quality of life change for the patients.”

As an investigator long involved in such research, he said many previous studies “completely failed.” Thus, Dr. Losordo added, “It's refreshing to finally have something that looks like a possible win. It's phase II, so we can't say for sure that this is a therapy that will move forward, but this is a large population of patients that is disabled with symptoms. If we could offer something beyond what we currently have I think that would be a very positive thing.”

Gene Therapy

Gene therapy requires that scientists match a disease, condition, or disorder with a gene mutation and then, find the mutation within an individual patient and insert a gene that corrects the problem. There has been remarkable progress in sequencing the human genome, as well as identifying some links among gene mutations or irregularities and specific diseases, disorders, and conditions. However, using these discoveries to treat patients remains highly experimental.

The good news is that researchers may be reversing the tide of disappointing data in recent years. Just before Thanksgiving (how appropriate!), Rob Logan, PhD, senior staff at the National Library of Medicine, cited three recent reports suggesting impressive progress in gene therapy.

In a study published in Science, investigators arrested the development of adrenoleukodystropy (ALD), in two children. ALD causes a degeneration of the fatty insulation of nerve cells, which results in progressive brain damage. The impact of the disease on patients and caregivers was the focus of the 1992 movie, 'Lorenzo's Oil.'

In a second study, reported by The Lancet in October, gene therapy restored the sight of five children and several adults with a rare, congenital eye disease. All patients had a gene mutation that prevented them from making a retina protein. An added gene (that remained in the body of each patient's cells) stimulated the development of the missing protein, which helped partially restore their vision.

A third study, reported in the New England Journal of Medicine, described how gene therapy overcame a rare immunological disorder in eight of 10 patients.

Dr. Logan said, “Now normally, we would not highlight three studies about experimental treatments for a different disease that provide preliminary results based on a few patients. However, the announcement of the successful ALD intervention in Science by itself resulted in an accompanying editorial titled 'A Comeback for Gene Therapy.'”

None of these therapies are ready for prime time yet, but it is very encouraging to finally be able to say that this revolution appears to be coming – this time, sooner as opposed to later.

Want to be Really Young at Heart? Exercise.

2009-11-18T11:18:00.001-07:00

We know being sedentary hurts the heart and it’s clear that being a Master’s athlete creates what can best be described as a youthful heart regardless of age. Is there any happy medium? I mean, 6-7 Master-level training sessions per week throughout life is probably a little beyond most people.

A new study suggests a lower level of lifelong exercise has major benefits. The researchers studied healthy people older than 65 years, who were without chronic diseases, such as high blood pressure or diabetes. The participants were recruited from another study (the Aerobics Center Longitudinal Study), in which they had been reporting their weekly activity for about the last 15 to 25 years.

For the study, participants had cardiopulmonary stress tests, ultrasounds of the heart and vessels, as well as a simultaneous heart catheterization and ultrasound (an echocardiogram) of the heart to determine the heart’s compliance and distensibility. (Essentially, how pliable is it? Does it keep its shape or start to lose it over time? A lifetime of living usually hardens the heart a bit, making it less compliant and more difficult to pump blood throughout the body. Heart failure is one common result to these kinds of changes to the structure of the heart.)

The greater the amount of lifelong exercise training — measured by the number of days per week exercised — the more likely individuals preserve the youthful compliance and distensibility of their heart. Specifically, for each increase in the number of exercise sessions per week, the benefits increase.

People who exercised six to seven times a week for 15 to 25 years (Masters athletes) retained 100% of their hearts’ youthful compliance and distensibility, leaving them with hearts similar to those of 30-year-olds. Those people able to exercise four to five times a week earned about 54% of the benefit observed in Master athletes, while two to three times a week achieved 42% of the benefit.

Overall, there appears to be a dose-response effect with exercise; exercise more and earn more heart health; do less, and you see less benefit – and you see it quite literally in terms of the measurable structure of your heart.

Brain Food: Vegetables Improve Mental Function

2009-11-18T10:19:00.000-07:00

Here’s the headline from the AHA press release: Vegetables, fruits decrease heart disease risk, all cause mortality, and improve mental function in seniors.

Disclaimer: OK, for this story I should note I have been a vegetarian for more than 25 years. (I eat eggs and dairy products, no meat or fish.) It’s not a conflict of interest because I don’t proselytize; many people who have known me for some time don’t know about my food preferences. So, it really doesn’t impact my reporting, but journalistic integrity says I should mention it.

Here are the study results in brief:

Researchers analyzed data from the largest national study of community-dwelling adults aged 70 years or older at the time they joined the study (1994-1996). Detailed assessment of participants dietary habits were analyzed as was global mental function.

All of this was done prospectively to examine risk of mortality in the national Longitudinal Study of Aging, involving 4,879 people. Participants were followed for an average of 7 years. The important finding: these older people did not have to consume truckloads of produce to see a benefit.

• People who ate 3 or more servings of vegetables per day had a 30% lower risk of death from heart disease, and a 15% lower risk of death due to any cause than those with less than 3 servings of vegetables per day. The difference was highly significant (p<0.001).
• Increased servings of vegetables and fruits meant a significantly lower risk of cognitive impairment. (In other words, less risk of memory loss, deteriorating visual processing, etc.)
• Fruit intake influenced risk of dying, too, but this affect was not as strong after adjusting for vegetable intake. So, at least for older individuals, it’s really the vegetables that made a big difference.

This time my comment is simply: No comment.

Is the Glass Half Full? Or are You at Higher Risk of Heart Attack?

2009-11-18T07:57:00.001-07:00

Do emotions and optimism really matter in relation to heart health? Two new studies provide some of the strongest evidence yet that both positive emotions and an optimistic attitude significantly reduce one’s risk of heart disease.

Researchers at Columbia University studied more than 1,600 healthy men and women who were enrolled in a long-term Canadian health study. The subjects were evaluated using standard scales to measure anxiety, hostility, and depression. Then researchers watched videotaped interviews to measure the positive emotions expressed by the study participants. A lot of other data were collected, too, including blood pressure, cholesterol levels, smoking status, and whether or not the participants had diabetes.

During the 10 years the study subjects were followed, 129 heart disease incidents occurred (121 nonfatal and 8 fatal). Of these 8% of study subjects who developed heart problems, those who expressed positive emotions more often were less likely to have a cardiac event, and those who experienced depression were more likely to have an event. This was true even after adjusting for various factors (such as age, sex, and standard risk factors). Hostility and anxiety did not predict coronary heart disease events.

The second study involved an even larger group of randomly selected men and women (2,380) and assessed individual levels of optimism. (It’s surprising how many tools are available to measure emotions and traits such as optimism.)

None of the study participants had coronary heart disease at baseline and, again, they were followed for 10 years, during which time 274 coronary events occurred, representing 11.5% of subjects. Those participants considered highly optimistic were less likely to have a coronary heart disease event during the study period compared to those with average and low levels of optimism. Again, after adjusting for important variables that could influence the outcome, level of optimism remained a significant factor influencing cardiac risk. There was a consistent effect, too, with low optimism showing the highest risk, average optimism showing average risk, and the most optimistic showing the least risk of a coronary heart disease event.

Most people interested in medicine want to know the mechanism; in this case, what explains the protective effect of positive emotions and optimism? There could be direct influences on physiology. For example, depression is known to have a variety of bad effects on the heart and vascular system. Or the explanation could be indirect via the influencing of health behavior, such as smoking. Maybe optimists just don’t feel the need to ever pick up a cigarette.

Whatever the explanation, it is good to see two studies with long-term follow-up in good-sized populations of patients. Many of the previously reported trials have gotten a lot of attention with far fewer people over much shorter periods of time. So, let me ask you: are optimistic about these results?

Heart Healthy Fish? Not if You Don't Cook it RIght

2009-11-17T13:15:00.001-07:00

Eating fish for your heart? How you cook it is very important.

If you eat fish to gain the heart-health benefits of its omega-3 fatty acids, how you prepare it matters a lot.

“It appears that boiling or baking fish with low-sodium soy sauce (shoyu) and tofu is beneficial, while eating fried, salted or dried fish is not,” said Lixin Meng, M.S., lead researcher of the study and Ph.D. candidate at the University of Hawaii at Manoa. In fact, she added, eating fried, salted or dried fish may contribute to your risk. We did not directly compare boiled or baked fish vs. fried fish, but one can tell from the (risk) ratios, boiled or baked fish is in the protective direction but not fried fish.”

The findings also suggest that the cardioprotective benefits of fish vary by gender and ethnicity — perhaps because of the preparation methods, genetic susceptibility or hormonal factors.

In this study, researchers examined the source, type, amount and frequency of dietary omega-3 ingestion among gender and ethnic groups. Participants were part of the Multiethnic Cohort living in Hawaii and Los Angeles County when they were recruited between 1993 and 1996. The group consisted of 82,243 men and 103,884 women of African-American, Caucasian, Japanese, Native Hawaiian and Latino descent ages 45 to 75 years old with no history of heart disease.

Overall, men who ate about 3.3 grams per day of omega-3 fatty acids had a 23% lower risk of cardiac death compared to those who ate 0.8 grams daily. “Clearly, we are seeing that the higher the dietary omega-3 intake, the lower the risk of dying from heart disease among men,” Meng said. Interestingly, for women, the omega-3 effect was cardioprotective at each level of consumption.

However, eating salted and dried fish was a risk factor in women. In contrast, adding less than 1.1 gram/day shoyu and teriyaki sauce at the dinner table was protective for men. But more was not better: adding more than 1.1 gram/day of such sauce was not beneficial. For women, shoyu use showed a clear inverse relationship to death from heart disease. Shoyu high in sodium can raise blood pressure, so she stressed low-sodium products. Eating tofu also had a cardioprotective effect in all ethnic groups.

“My guess is that, for women, eating omega-3s from shoyu and tofu that contain other active ingredients such as phytoestrogens, might have a stronger cardioprotective effect than eating just omega-3s,” said Meng, noting that further studies are needed to confirm the hypothesis.

Comment: There is good reason to tell your doctor about all supplements you take. For example, excessive intake of omega-3 fats tends to prevent blood from clotting and may cause excessive nose bleeding.

Hmmm: Getting Away from Men Reduces Depression in Women.

2009-11-17T13:02:00.000-07:00

In a world where just about everything is co-ed, maybe there’s room for occasional gender separation. A new study shows that depressive symptoms improved among women with coronary heart disease who participated in a cardiac rehabilitation program exclusively for women.

Depression is common in people with heart disease and is more evident in women. There are reported physiological effects that could make heart disease worse, but there are psychological and practical issues, too. Being depressed interferes with adherence to lifestyle modifications and the willingness to attend rehab, which makes it harder for people to recover.

“Women often don’t have the motivation to attend cardiac rehab particularly if they’re depressed,” said Theresa Beckie, Ph.D., lead investigator and author of the study and professor at the University of South Florida’s College of Nursing in Tampa, Florida. “Historically women have not been socialized to exercise and their attendance in cardiac rehabilitation programs has been consistently poor over the last several decades. This poor attendance may be partly due to mismatches in stages of readiness for behavior change with the health professional approaching from an action-oriented perspective and the women merely contemplating change – this is destined to evoke resistance.”

Cardiac rehabilitation programs tailored to the needs of women and to their current level of readiness to change may improve adherence to such programs and potentially improve outcomes for women, she said.

The primary goals of the 5-year randomized clinical trial were to compare multiple physiological and psychosocial outcomes of women who participated in a 12-week stage-of-change matched, motivationally enhanced, gender-tailored cardiac rehabilitation program exclusively for women compared to women attending a 12-week traditional cardiac rehabilitation program comprised of education and exercise.

“We didn’t push them if they weren’t ready to make the changes,” Beckie said. “We have found that if some patients receive long lists of behaviors they are expected to change immediately — such as quitting smoking, eating healthier, exercising regularly — they are overwhelmed. Pushing such patients who are not ready can lead them to tune out or drop out. Instead, for these women, we acknowledged their ambivalence about change and gave them strategies to move toward being ready by reinforcing their own motivations for changing. It’s unrealistic to expect all patients to change their lifestyle all at once, right now in front of you.”

The woman-centered program was a more individualized approach to rehabilitation, she said, adding, “You can’t treat everyone the same when it comes to changing health behaviors.”

Heart Disease for Mummies

2009-11-17T12:57:00.000-07:00

Civilization causes heart disease. That’s one way to look at data from researchers who found hardening of the arteries in 3,500-year-old mummies. The lesson is we may have to look beyond modern risk factors to fully understand heart disease.

We have an idealized image of living in ancient societies: fruits, nuts, berries, and the occasional wild animal meat. At the other end of the time warp, we look around us today and ascribe artery-clogging cardiovascular disease to modern risk factors. But now we have evidence from ancient Egyptian mummies that ancient societies suffered heart attacks and strokes, too.

The study, presented by Randall C. Thompson, M.D., professor of medicine at the Mid America Heart Institute in Kansas City, was conducted by a unique collaboration of imaging experts, Egyptologists and preservationists who sought the most direct evidence possible. Using six-slice computed X-ray tomography (CT) scans, they examined 20 mummies housed in the Museum of Antiquities in Cairo, Egypt to see if heart and blood vessel tissue was present and to learn its condition.

Definite atherosclerosis, in other words a build-up of fat, cholesterol, calcium and other substances in the inner walls of blood vessels, was present in three mummies and probable atherosclerosis was apparent in another three. Calcification was significantly more common in the mummies estimated to be 45 years or older at the time of death. Men and women were similarly affected.

Thus, clogged arteries is not only a disease of modern man, but was not unusual in humans living 3000 years ago.

Why? That’s unclear, but one researcher (L. Samuel Wann, MD) told me that once civilizations were established, farming took off and food stocks became more abundant and reliable. Perhaps, people ate more and gained weight – and the rest, as they say, is history.

2009-11-17T12:06:00.000-07:00

In one generation, overweight and obesity triples in kids,making for higher risk of heart disease as adults.

Between the mid-1980s and 2008 – the span of just one generation – the prevalence of overweight and obese children has tripled. According to the American Heart Association and the Centers for Disease Control and Prevention (CDC), an estimated 31.9% of U.S. children and adolescents are now overweight or obese. (About 16% of all children and teens in the U.S. have zoomed beyond just being overweight and are officially obese.) As the AHA puts it, “The cardiovascular fallout from this epidemic in the decades ahead will challenge the healthcare system.”

Two pieces of good news:

• Children’s Hospital, Denver: Heart function improves quickly after morbidly obese teens undergo bariatric surgery, and continues to improve for at least 2 years.

• University of Leipzig Heart Center, Germany: Regular exercise narrows the fitness gap between students from different backgrounds. Specifically, adding an exercise program to a high school curriculum dramatically improves physical fitness levels in teens from lower socio-economic backgrounds. (These kids started out with significantly higher body mass index and lower lean body mass, as well as poorer results in cardio-respiratory fitness testing compared to kids from higher income areas. This gap was reduced with the addition of an exercise program to school curriculums.)

2009-11-17T08:26:00.001-07:00

Talk about a teachable moment: Watch yourself having a heart attack!

Oh wad some power the giftie gie us
To see oursel’s as others see us!

The poet Robert Burns would have enjoyed this: Smokers who watch simulated videos of themselves having a heart attack are more likely to be more successful in stopping smoking. Talk about a teachable moment!

Researchers inserted photographs of 13 smokers (average age 45) with no related illness, their nonsmoking partner and family members into a video depicting the smoker having a heart attack — with all the potential personal and family consequences.

Seven participants had observable responses to the video including looking uncomfortable, red eyes and difficulty speaking. Self reports included “awareness of the important things” and “feeling it was very real.”

Researchers evaluated carbon monoxide levels and smoking status at baseline, 1 week, 3 months and 6 months. At week one, they found that: Seven smokers reported they had stopped smoking (four people also used quitting aids). The daily average cigarette consumption fell from 17.3 to 2.7 cigarettes. Carbon monoxide levels decreased from 15.7 to 3.1 ppm (parts per million).

At 6 months, seven of the 13 participants still weren’t smoking. (And no, it was not just those who ad emotional reactions to the video simulation)

There was 3 months of face-to-face counseling, too, for the participants, so it's hard to determine how much of the response seen in this study was due to just the video. But it certainly is promising.

One suggestion for upping smoking cessation rates even further: After the video, have a lawyer present offering discounted will preparation services.

2009-11-16T13:53:00.001-07:00

Little things mean a lot: Extra serving of fruit/vegetables each day reduces inflammation and cardiovascular disease risk.

Speaking of omega-3 fatty acids (as we were very recently!), increased fruit and vegetable intake plus additional omega-3 fatty acid intake decreases levels of inflammation and blood cholesterol linked to cardiovascular disease (CVD) in family members of CVD patients.

The study involved family members of patients enrolled in a National Heart Lung and Blood Institute-sponsored trial. At baseline and at 1 year, the 501 people in the study underwent diet assessment via questionnaire and measurement of blood fats and biomarkers of inflammation, including high sensitivity C-reactive protein (hsCRP). Inflammation has been linked to CVD; in general, the higher the hsCRP the higher the risk and the lower the hsCRP the lower the risk of CVD.

After adjusting for age, race, gender, smoking, family history of CVD, physical activity and other factors, investigators found that a one-serving increase in daily fruit/vegetable consumption and a 1 gram per day increase in omega-3 fatty acids were each associated with significant reductions in hsCRP. Also, 1 gram per day reductions in saturated fat and trans fat were associated with reductions in total and LDL cholesterol.

Comment: The message from this study should be put in neon and hung in everyone’s kitchen: even small diet changes can have big consequences. Think about it: Here is a group of people who are family members of patients with CVD, so these study participants were themselves at increased CVD risk due to the genes and lifestyle habits they share with the CVD patient. What a great group of people to study! Let's hope they all get a copy of the results.

Soy what? A modified soybean oil may be as effective as fish oil in preventing heart attacks.

The American Heart Association recommends eating two servings per week of fatty fish which is high in EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), like mackerel, lake trout, herring, sardines, albacore tuna, and salmon. Eating these fish, which have high levels of omega-3 fatty acids, has been associated with a decreased risk of cardiovascular disease. However, many Americans don’t like eating fish because of the taste, preparation, and/or concern that it may be contaminated by mercury or other pollutants.

Here at the AHA meeting, investigators evaluated a new type of oil from soybeans that have been modified through biotechnology to produce increased levels of omega-3 EPA in red blood cells. “This soybean oil could be an effective alternative to fish oil as a source of heart-healthy omega-3 fatty acids,” said William Harris, Ph.D., lead author of the study and chief of cardiovascular health research at Sanford Research/USD and professor of medicine at Sanford School of Medicine at the University of South Dakota in Sioux Falls. “We know that giving pure EPA to people reduces their risk for heart disease. “Presumably, if you gave this special soybean oil to people, you’d do the same thing — reduce heart attacks.”

Harris and his colleagues recruited healthy volunteers in Cincinnati, Sioux Falls and Chicago into the double-blind study. “Our goal was to see if the oil from the genetically engineered soybean would raise red blood cell levels of EPA,” he said.

EPA levels rose 17.7% in the individuals given the enriched soybean oil and 19.7% in a group receiving pure EPA plus regular soybean oil. Regular soybean oil, like you’d buy at the grocery store, did not raise cellular EPA levels at all.

Dr. Harris said, “This oil could make a major contribution to our national omega-3 intake. The supply could be virtually endless, and it would provide omega-3s without putting additional pressure on fish stocks. What’s more, it will be free of contamination from mercury, PCBs or dioxins, the harmful things that can get into some types of fish,” he said. “Our next step is to formulate this SDA soybean oil into food products such as breakfast bars, yogurts and salad dressings, and then do a study to see if it is absorbed by the body and converted to EPA.”

Let the sunshine in: Heart disease plus too little vitamin D = depression.

In recent weeks, there have been a number of interesting reports on vitamin D in the news. For example, our attempts to limit sun exposure to reduce skin cancer may have an unexpected affect on our brains. http://bit.ly/1Lae1V Small-scale studies have documented low vitamin D levels in children and adolescents, even as evidence mounts about the critical role of this vitamin in maintaining health and preventing disease. In one large study of 6,000 kids in the United States, 7 of 10 had low levels of vitamin D, raising their risk of bone and heart disease. http://bit.ly/1600pT

In a report to be presented later today at the American Heart Association Scientific Sessions (the embargo has been lifted, that’s why I can tell you about it), investigators evaluated about 9,000 people with cardiovascular disease. Very low levels of vitamin D were associated with depression; this was particularly evident among those with no prior incidence of depression.

And yes, winter (when many people see little sun for days on end), enhanced the association overall and was even a factor in those people who had never before had a diagnosis of depression.

Comment: Another recent report found that too little vitamin D nearly doubles heart disease risk in diabetics. Clearly vitamin D is important. http://bit.ly/3Jn70G If you’re concerned about skin cancer, maybe you should try to consume more dairy products; even low-fat and skim milk is rich in vitamin D. Another option is to take vitamin supplements, although I prefer not to make blanket recommendations that we all need to be popping vitamin pills every day. A multi-vitamin with vitamin D might be valuable (and not JUST for the vitamin D). Clearly, the weight of the evidence suggests many of us are getting far too little of this critical vitamin, so taking personal steps to up our intake a little might be very beneficial.

Some Wii programs produce the equivalent of moderate-intensity exercise. #SS09

OK, so maybe your kid – the one who can’t be ripped from his (or her) video games – may actually find a job after all that involves their passion (obsession?). A number of new approaches to health rely on Wii technology. Although I can't confirm it, I suspect a number of these new program developers were video game players when they were younger and may have even been in that hard core group referred to derisively as vidiots. Parents, if you are stressed about your kids' obsessive game playing, you might want to relax a little. Maybe all this obsessive playing could lead to a research career.

For example, the Nintendo system could save lives. This was the conclusion of some experts after a group of students developed a program to teach CPR using a Wii. http://bit.ly/nDFcu Older adults are benefiting when they use Wii because it turns the games enhance physical movement, thereby helping build coordination and agility while playing virtual tennis, bowling, or darts on a Wii system. Also, a number of studies are now or will soon be underway to evaluate video games for their ability to boost thinking skills among the elderly. http://bit.ly/4BBJDL Even the Mayo Clinic recently summarized the work in this field by noting that interactive video games have a role in good health. http://bit.ly/2cia0y

In this latest report, presented at the 2009 American Heart Association Scientific Sessions, researchers found that some Wii sports and Wii fit activities can increase adults’ energy expenditure as much as moderately intense exercise. The study was done under the auspices of the National Institute of Health and Nutrition in Tokyo, Japan, and funded by Nintendo. The investigators found that “the range of energy expenditure in these active games is sufficient to prevent or to improve obesity and lifestyle-related disease, from heart disease and diabetes to metabolic diseases.”

Of the games studied, boxing was the most effective for increasing energy expenditure, with golf, bowling, tennis and baseball associated with more moderate exercise levels. The most effective Wii fit exercise was the single-arm stand, which involves standing up and lying down. The intensities of yoga and balance exercise (using the Wii system) were significantly lower than those of resistance and aerobic exercise, but these exercises still could improve flexibility and help in fall prevention.

Motohiko Miyachi, Ph.D., lead author of the study, plays active video games himself and recommends these active games rather than sedentary video games. The study’s findings about energy expenditure, he said, apply to Americans as well as Japanese and to younger and older people.

Too little fat? For people with the cluster of problems known as metabolic syndrome, moderate- beats low-fat diet.

A moderate-fat diet (40% fat/45% carbohydrates/15% protein) more effectively reduces cardiovascular risk than a low-fat diet of (20% fat/65% carbs/15% protein) in patients with the cluster of problems known as metabolic syndrome (or MetS). Think of MetS as an unwelcome group of dangerous house guests: obesity, high triglycerides, low levels of good cholesterol (called high density lipoprotein or HDL), elevated fasting glucose, and high blood pressure. None of these do you (and your heart) any favors, but when they gang up on you in your body, the outcome is not pretty (heart attack, premature death, maybe stroke).

In this small study of 64 men and women, participants underwent different diets for 4 weeks. In this first comparison of low-fat vs. moderate-fat diets in people with MetS, moderate-fat compared to low-fat diet did a better job of reducing cardiovascular disease risk. Why? The low-fat diet had more carbs, which could have been deleterious depending on the types of carbohydrates eaten.

Comment: For most Americans, a low-fat diet is very hard to maintain. For the huge number of Americans with the galaxy of problems known as metabolic syndrome, the good news from this study is you don’t have to eat a diet that makes you think your taste buds have died. Moderation in everything and, at least in these particularly high-risk people, that means a diet you can live with.

For high-risk heart disease, statin + niacin (a B vitamin) beats adding another drug (ezetimibe).

Twenty years ago, Robert E. Kowalski, PhD, drew widespread public attention to the value of niacin therapy for reducing heart disease. He pretty much made niacin a household word via his best selling book “The 8-Week Cholesterol Cure.” (The clinical use of niacin extends over 50 years, but Bob popularized the potential of this B vitamin when used in very high doses.) In the ensuing years, dozens of studies have established the heart healthy effects of niacin when used alone or when combined with a statin.

Bob was a good friend of mine and 20 years ago, based on his book and our long conversations, I decided to start myself on over-the-counter high-dose statin therapy. This seemed prudent given my family history of heart disease (from every side of my family!) and the fact I already had what today would be considered borderline high cholesterol. Today my LDL (bad cholesterol) is 28 and my HDL (good cholesterol) is 86. Is that good? My own doctor said I have a higher risk of being hit by a semi than having a heart attack. A cardiology friend put it more colorfully when he suggested that if my wife is waiting for me to drop dead she’s going to have to get a gun.

Clearly, I am biased in favor of niacin. With that disclaimer in full view, a new study reported at the 2009 American Heart Association Scientific Sessions is an important addition to the clinical literature on how to best treat people already on statin therapy but still not at their target cholesterol levels. Two approaches were evaluated in the ARBITER 6-HALTS study: adding extended-release niacin (Niaspan) to increase HDL levels or a different kind of LDL cholesterol-lowering drug called ezetimibe (known as Zetia). Not only did combining niacin with statin therapy produce superior outcomes, it appeared to cause disease regression as opposed to the niacin/ezetimibe combination which only halted the progression of cardiovascular disease.

In an editorial that accompanied the publication of the study in the New England Journal of Medicine, the authors (who were not part of the study) summarized the importance of ARBITER 6-HALTS. They said the findings provide “…support for the concept that the use of statins to reduce LDL cholesterol to target levels with the subsequent addition of a drug to raise HDL cholesterol levels (niacin), rather than a drug to lower LDL cholesterol levels (ezetimibe), is a more effective treatment for patients at high cardiovascular risk.” (Read the NEJM editorial here http://bit.ly/1T0Rru )

As much as I like not having to pay for a prescription drug, and telling myself that I am only taking a vitamin, I very much realize that at the levels of niacin required for effectiveness (in this trial, 2000 milligrams every day) this vitamin is powerful drug therapy. After all, the U.S. Recommended Daily Allowance for niacin is 20 milligrams per day! It’s hardly just a vitamin supplement when taken at 100 times the daily RDA every day for years (or decades!).

So, niacin is highly effective therapy, but remember: it is, for all intents and purposes, a drug and should be treated as such. Tell your doctor before you start taking it!

Cool! Chilling the brain with nasal cooling device during CPR may be a simple way to increase survival after cardiac arrest.

Recently, people hospitalized after cardiac arrest have been cooled to reduce injury to the brain and other tissues. Evidence suggests that this procedure, known as “therapeutic hypothermia,” reduces damage that occurs when the blood supply returns after being temporarily halted during cardiac arrest.

However, standard body cooling may not cool the brain soon enough or well enough to prevent neurological damage. (Saving your heart but not your brain is NOT a desirable outcome!) One problem has to do with the simple biophysics of cardiac arrest. Body cooling works if there is blood that travels to the brain leading to protective lower brain temperatures. Without blood circulation (as in cardiac arrest) or less than optimal blood flow (which may occur with prolonged CPR) it’s hard to quickly lower brain temperature. Also, waiting until a patient arrives at the hospital may delay neuroprotective cooling by an hour or more.

Now, in the PRINCE (Pre-Resuscitation Intra-Nasal Cooling Effectiveness) study, investigators at 15 centers across Europe used a new tool, RhinoChill, that cools the brain during ongoing cardiopulmonary resuscitation (CPR). (The name has nothing to do with the animal; “rhinos” is Greek for nose.) RhinoChill is a non-invasive device that introduces coolant through nasal prongs. The system is battery-powered, simple to operate, and requires no refrigeration, making it highly suitable for use by emergency medical technicians while delivering CPR and other necessary out-of-hospital emergency treatment.

In this randomized study, 46.7% of those cooled survived to hospital discharge, compared with 31% who receiving standard care. Those who received treatment fastest (under 10 minutes) had the best outcomes.

This technology will likely be available in Europe in early 2010, with studies continuing here in the United States.

Incidence of sudden cardiac death three times higher for men; African-American heritage also increases risk. #SS09

Sudden cardiac death (SCD) occurs from an abrupt loss of heart function, and victims are often unaware that they are at risk. Coronary heart disease due to blocked arteries is a common underlying cause of SCD. Another common cause are heart rhythm disorders; sometimes the heart beats rapidly (ventricular tachycardia) or chaotically (ventricular fibrillation) or both.

Researchers examined SCD data from three famous studies: Framingham Heart Study (FHS), the Cardiovascular Health Study (CHS) and the Atherosclerosis Risk in Communities (ARIC) study. Lifetime risk was associated with three different variables: cardiac risk factors (of course), male gender, and African-American heritage. For example, the lifetime risk of SCD was one in eight for men and one in 24 for women.

Less sudden than thought? About two-thirds of cardiac arrests are preceded by symptoms. Good news IF you recognize symptoms.

A team of researchers in Japan report that about two-thirds (61%) of sudden cardiac arrests were preceded by well-known cardiac symptoms. The most frequent symptoms included shortness of breath, chest pain and/or fainting – 59.8% a few minutes before arrest and 25% within an hour before.

Comment: In the first report, its importance derives from the studies analyzed. Individually, these are three of the largest cardiac and health data sets in the United States, so using these studies to evaluate a specific question provides insights likely to be very reliable.

As for the second study, this is critically important. Previous data suggested that for about half of all people with SCD the first symptom is sudden death. How do you like that for a first symptom? This study, however, says that in many cases there are symptoms that something’s wrong. Unfortunately people (yeah, mostly men) don’t want to think of symptoms as being a heart attack. A doctor even told me once of getting a call from a cardiology colleague who said he wasn’t feeling well and described the symptoms of a heart attack! Even trained cardiologists (again, in this case, a man) may want to think it’s that pepperoni pizza they just ate that’s the problem and not a heart attack.

Please: Learn more about heart attacks. We wrote this for the American College of Cardiology’s patient website known as CardioSmart. http://bit.ly/2Pn5E0 And if you’re alone when these symptoms strike, and you’re too stubborn to call 911, call a friend or go somewhere with plenty of people. At least then, when your heart stops, there is a chance someone will call 911 for you and maybe perform CPR so you can live again – when you hopefully will take better care of yourself.

Athletic trainers use a novel cost-effective screening method to ID athletes who may be at risk of sudden death.

Sudden cardiac death (SCD) occurs from an abrupt loss of heart function, and victims are often unaware that they are at risk. Coronary heart disease caused by blocked arteries is a common underlying cause of SCD. Cardiac rhythm disorders are also responsible for many of these deaths. These occur when electrical impulses in the heart become rapid (ventricular tachycardia) or chaotic (ventricular fibrillation), or both. Such sudden deaths in younger persons are especially perplexing.

In an encouraging study, athletic trainers in 10 Houston high schools took part in a new screening method. Using a laptop computer, the trainers performed electrocardiograms (EKGs) on 2,057 student athletes and transmitted their results to a cardiologist. They discovered abnormal EKGs in 186 of these young people.

Comment: When a young athlete dies suddenly, the tragedy affects not only the family but usually an entire community, too. Unfortunately, this is such a rare occurrence that widespread screening to detect kids at risk is expensive and puts an additional burden on an already overworked health care system. What this study suggests is that athletic trainers, coaches, nurses and even students could perform the EKG. (Combining today’s computer power with amazing software is simplifying science to a degree that – well, no longer requires an advanced degree!) At the other end of this new screening tool, cardiology fellows could read the EKG. So, this could be a very economical way to screen for hidden heart disease in young athletes.

While no one suggests sudden cardiac death would be eliminated in young athletes, researchers said the discovery of significant heart problems in this study implies that the risk could be reduced. The model, with modifications, could be applicable to school districts nationwide.

Links: If you’re a doctor, what do you ask in a preparticipation medical screening? Some official recommendations here. http://bit.ly/3OLq3Y For more information, here is an article we prepared for the American College of Cardiology. http://bit.ly/1NDGMs

Expanding athlete program to a general population of young people may ID teens at risk of sudden death.

In this Italian study, screening 2,013 people (average age 18) with a health questionnaire and 12-lead (EKG) revealed 6.9% had a family history suggesting sudden cardiac death (SCD) or a family history of a condition (hereditary cardiomyopathy). Either of these family histories indicates that the student is at greater than normal risk of SCD. Another important finding: 10.4% of those studied had a 12-lead EKG abnormality warranting further investigation. (In other words, it might not have been a big problem, but something about the analysis of their heart suggested a need for further testing.)

Comment: Italian physicians have been way ahead of the rest of the world in screening young people (especially young athletes) for undetected cardiac disease. It’s been a huge debate. Widespread preparticipation screening, for example, is demanding, expensive, and requires commitment of the medical community, schools, and government. However, the experience in Italy is encouraging. Add in the Houston study above and soon we may see fewer of those terrible moments when we lose a young person suddenly from a problem that simply went unrecognized.

Valve Disease: Encouraging Reports on Less Invasive Procedures

2009-11-14T22:20:00.000-07:00

Aortic valve replacement is the most common heart valve procedure. It’s usually due to a slowly narrowing of the valve due to a growing blockage or “stenosis.” It is a consistently progressive disease affecting from 2-7% of individuals older than 65 years in the U.S. As bad as that is, it will only get worse as the population ages.

Surgical valve replacement remains the gold standard for treating advanced aortic valve stenosis. However, up to one-third of patients with symptomatic aortic stenosis are not candidates for open surgery. Sometimes, they are simply too old or have other diseases that complicate any open surgical procedure.

For at least 5 years, I have been reporting on percutaneous valve repair or replacement. (If you’re a physician, check ACC’s Cardisource for much of our work on this topic. In particular, look for interviews by or features with Dr. Peter Block of Emory University. He was an early investigator and still one of the recognized U.S. authorities on this topic.) One of the world’s leading investigators is Dr. Helene Eltchaninoff, University of Rouen, France. Hers was the first session I attended this year at AHA and the results continue to be promising. I am scheduled to interview Dr. Eltchaninoff, so we’ll post more details later. (If you are a doctor, you might be interested in seeing Dr. Eltchaninoff's slides at http://bit.ly/2lctg5 )

For now, if you want to know more about valve disease, here is a good summary for patients that we wrote for CardioSmart, a website developed by the American College of Cardiology. http://bit.ly/2Nk1oZ

The Heart of the Matter

2009-11-14T14:08:00.000-07:00

For nearly 25 years, I have been covering the American Heart Association Scientific Sessions. I am in Orlando and, starting tomorrow, we'll be providing details and perspectives on dozens of the leading stories from this meeting.

Heart disease and stroke have such a huge impact on health worldwide and this meeting always provides new insights that change the prevention, detection, and management of cardiovascular disease.

We'll link you to additional sources, too, but I think you'll enjoy the opportunity to tap into this huge pipeline of information. (There are thousands of presentations; we'll try to narrow the focus down to the most interesting/influential work being presented here.)
