If you'd like to gain huge quantities of weight, here's a number of helpful tips:

1) Follow the advice of food manufacturers and eat the products they label "healthy", or "heart healthy", or "part of a nutritious breakfast" etc., like Shredded Wheat cereal, pretzels ("a low-fat snack"!), low- or non-fat salad dressings.

2) Cut your morning calorie intake by skipping breakfast.

3) Hang around with other heavy people. They will confirm that it's okay to be overweight.

4) Call walking your dog "exercise".

5) Get a sedentary desk job. Use your swivel desk chair to scoot about whenever possible, rather than getting up to do things.

6) Say "I've worked hard all week long. Weekends are for relaxing, not for physical activities. I deserve a rest."

7) Eat foods without thinking about it: Eat chips while watching football, eat while on the phone, daydream over the sink.

8) Eat to provide comfort when stressed.

9) Eat foods that have sentimental value, whether or not they're good for you: Freshly-baked cakes that remind you of Mom, Pop Tarts that you used to carry in your lunchbox when you were a kid, hot dogs just like Dad would buy at the baseball stadium.

10) Cut back on sleep and generate insatiable starch cravings.

11) Stack your shelves at home with great variety. That way, you'll always have something to suit your mood.

12) Say to your spouse: "It's none of your damn business what I eat! I'm a grown man/woman!" Prove it by over-indulging in obviously unhealthy foods.

13) Tell yourself that you're just too busy to pay attention to food choices. Just grab whatever you can out of a convenience store or vending machine.

See, it's easy! And that just a start.

Of course, I don't really want you to do any of these things. But if you see yourself in any of the above, and you're struggling with weight, you should seriously rethink your approach.

I've seen this happen many times. Despite the great media exposure and the growing acceptance of my colleagues, heart scans still trigger wrong advice. I had another example in the office today.

Henry got a CT heart scan in 2004. His score: 574. In his mid-50s, this placed him in the 90th percentile, with a heart attack risk of 4% per year. Henry was advised to see a cardiologist.

The cardiologist advised Henry, "Oh, that's just a 'false positive'. It's not true. You don't have any heart disease. Sometimes calcium just accumulates on the outside of the arteries and gives you these misleading tests. I wish they'd stop doing them." He then proceeded to advise Henry that he needed a nuclear stress test every two years ($4000 each time, by the way). No attempt was made to question why his heart scan score was high, since the entire process was outright dismissed as nonsense.

I'm still shocked when I hear this, despite having heard these inane responses for the past decade. Of course, Henry's heart scan was not a false positive, it was a completely true positive. I'm grateful that nothing bad happened to Henry through two years of negligence, though his heart scan score is likely around 970, given the expected, untreated rate of increase of 30%.

The cardiologist did a grave disservice to Henry: He misled him due to his ignorance and lack of understanding. I wish Henry had asked the cardiologist whether he had read any of the thousands of studies now available validating CT heart scans. I doubt he's bothered to read more than the title. The cardiologist is lucky (as is Henry) that nothing bad happened in those two years.

Do false positives occur as the cardiologist suggested? They do, but they're very rare. There's a rare phenomenon of "medial calcification" that occurs in smokers and others, but it is quite unusual. >99% of the time, coronary calcium means you have coronary plaque--even if the doctor is too poorly informed to recognize it.

Do you know what's better than a heart scan?

Two heart scans. No other method can provide better feedback on the results of your program.

Say you've made efforts to correct high LDL; lost weight to raise HDL and reduce small LDL; added soluble fibers, nuts, and dramatically reduced wheat products; take fish oil, vitamin D, and follow a flavonoid-rich diet. Has it worked?

After a year or so of your program, that's when another heart scan can give you invaluable feedback on whether it's been successful. I tell my patients that it's relatively easy to correct lipid and lipoprotein abnormalities. The difficult part is to know when it's good enough. Is your LDL of 67 mg/dl and HDL of 50 mg/dl good enough? Another heart scan score is the best way I know of to find out.

Variation in plaque growth differs hugely from one person to another, even at equivalent lipoprotein values. Why? Lots of reasons. Humans are inconsistent day to day. Lipoproteins, being a snapshot in time and not a cumulative value, change somewhat from day to day. There's also the possibility of unmeasured, unrecognized factors that influence coronary plaque growth. We may not be smart enough to identify these hidden factors yet. But your heart scan score will incorporate the effects of these hidden factors.

Ideally, we aim for zero growth in plaque (no change in score) or a reduction. But, particularly in the first year, 10% or less plaque growth is still a good result that predicts much reduced risk of heart attack. More than 20% per year and your program needs more work--or else you know what's ahead.

Let me paint a picture. It's fictional, though a very real portrait of how things truly happen in life.

Michael is an unsuspecting 40-year old man. He hasn't undergone any testing: no heart scan, no lipids or lipoproteins. But we have x-ray vision, and we can see what's going on inside of him. (We can't, of course, but we're just pretending.) Average build, average lifestyle habits, nothing extraordinary about him. His lipids/lipoproteins at age 40:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

At age 40, with this panel, his heart scan score is 100. That's high for a 40-year old male.

Fast forward 10 years. Michael is now 50 years old. Michael prides himself on the fact that, over the past 10 years, he's felt fine, hasn't gained a single pound, and remains as active at 50 as he did in 40. In other words, nothing has changed except that he's 10 years older. His lipids and lipoproteins:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

Some of you might correctly point out that just simple aging can cause some deterioration in lipids and lipoproteins, but we're going to ignore these relatively modest issues for now.)

Lipids and lipoproteins are, therefore, unchanged. Michael's heart scan score: 1380, or an approximate 30% annual increase in score. (Since Michael didn't know about his score, he took no corrective/preventive action.)

My point: If we were to make our judgment about Michael's heart disease risk by looking at lipids or lipoproteins, they would'nt tell us where he stood with regards to heart disease risk. His lipids and lipoproteins were, in fact, the same at age 50 as they were at age 40. That's because measures of risk like this are snapshots in time.

In contrast, the heart scan score reflects the cumulative effects of life and lipids/lipoproteins up until the day you got your scan.

Which measure do you think is a better gauge of heart attack risk? I think the answer's obvious.

The recognition of the metabolic syndrome as a distinct collection of factors that raise heart disease risk has been a great step forward in helping us understand many of the causes behind heart disease.

Curiously, there's not complete agreement on precisely how to define metabolic syndrome. The American Heart Association and the National Heart, Lung, and Blood Institute issued a concensus statement in 2005 that "defined" metabolic syndrome as anyone having any 3 of the 5 following signs:

Waist size 40 inches or greater in men; 35 inches or greater in women

Triglycerides 150 mg/dL or greater (or treatment for high triglycerides)

HDL-C <40 mg/dL in men; <50 mg/dL in women (or treatment for reduced HDL-C)

Blood Pressure >130 mmHg systolic; or >85 mmHg diastolic (or drug treatment for hypertension)

Glucose (fasting) >100 mg/dL (or drug treatment for elevated glucose)

Using this definition, it has become clear that meeting these criteria triple your risk of heart attack.

But can you have the risk of metabolic syndrome even without meeting the criteria? What if your waste size (male) is, 36 inches, not the 40 inches required to meet that criterion; and your triglycerides are 160, but you meet none of the other requirements?

In our experience, you certainly can carry the same risk. Why? The crude criteria developed for the primary practitioner tries to employ pedestrian, everyday measures.

We see people every day who do not meet the criteria of the metabolic syndrome yet have hidden factors that still confer the same risk. This includes small LDL; a lack of healthy large HDL despite a normal total HDL; postprandial IDL; exercise-induced high blood pressure; and inflammation. These are all associated with the metabolic syndrome, too, but they are not part of the standard definition.

I take issue in particular with the waist requirement. This one measure has, in fact, gotten lots of press lately. Some people have even claimed that waist size is the only requirement necessary to diagnose metabolic syndrome.

Our experience is that features of the metabolic syndrome can occur at any waist size, though it increases in likelihood and severity the larger the waist size. I have seen hundreds of instances in which waist size was 32-38 inches in a male, far less than 35 inches in a female, yet small LDL is wildly out of control, IDL is sky high, and C-reactive protein is markedly increased. These people obtain substantial risk from these patterns, though they don't meet the standard definition.

To me, having to meet the waist requirement for recogition of metabolic syndrome is like finally accepting that you have breast cancer when you feel the two-inch mass in your breast--it's too late.

Recognize that the standard definition when you seen it is a crude tool meant for broad consumption. You and I can do far better.

DHEA, the adrenal gland hormone, has suffered its share of ups and downs over the years.

Initially, DHEA was held up as the fountain of youth with hopes of turning back the clock 20 years. Such extravagant dreams have not held up. But DHEA can still be helpful for your program.

All of us had oodles of DHEA in our bodies when we were in our 20s and 30s. Gradually diminishing levels usually reach nearly blood levels of around zero by age 70.

In our heart disease prevention program, of course, we aim to stop or reduce your CT heart scan score. Does DHEA reduce your score? No, it most certainly does not. But it can be helpful for gaining control over some of the causes behind coronary plaque.

For instance, DHEA can:

--Help reduce abdominal fat and increase muscle mass (slightly)
--Provide more physical stamina.
--Boost mood.
--It may modestly reduce some of the phenomena associated with the metabolic syndrome (high blood pressure, high blood sugar, high insulin, low HDL, small LDL, etc.)

In my experience, people who feel better do better on their overall program. If you're always tired and run down and run out of steam by 3 pm, I won't see you riding your bicycle outdoors or at the aerobics class. But if you're bursting with energy until you put your head on the pillow, you're more inclined to walk, bike, dance, play with the kids, dance, take Tai Chi, etc.

Some downsides to DHEA: Some people experience aggression. Backing off on the dose usually relieves it. Also, sleeplessness. Taking your DHEA in the morning usually fixes it.

The dose is best tailored to your age and blood levels. People less than 40 years old should not take DHEA. The older you are, the higher the dose, though we rarely ever have to exceed 50 mg per day. If you've never had a blood level and your doctor refuses to obtain one, 25 mg per day is a reasonable dose (10-15 mg in women 40-50 years old). It's always best to discuss your supplement use, particularly agents like DHEA, with your doctor.

At a social gathering this weekend, as we humans like to do, someone asked me what I did for a living. I told him I was a cardiologist.

"What hospital do you work at?" he asked.

This is invariably the response I get whenever I tell people what I do. I wouldn't make much of it except that it happens just about every time.

This indicates to me just how successful hospitals, my colleagues, cardiac device manufacturers, and others supporting the status quo in heart care, have been in persuading us that the place for heart disease is the hospital--period.

Tense families, drama, high-tech...It all takes place in the hospital.

Yet the people destined to be the fodder for hospital heart care are presently well, mostly unaware of what the future holds. Also unaware that heart disease is readily, easily, inexpensively, and accurately identifiable. Ask anyone in the Track Your Plaque program who's had a CT heart scan.

We all need to rid ourselves of the idea that the hospital is the place for heart disease. If the coronary plaque behind heart attack is easy to detect and controllable, there's little or no need for the hospital for the vast majority of us.

In the majority of instances of coronary disease, the hospital should be the place for the non-compliant and the ill-informed, and not for those of us sufficiently motivated to know and do better. The formula is simple: 1) Quantify plaque with a CT heart scan, 2) Identify the causes, then 3) Correct the causes.

I came across this Blog authored by a nutritionist when it was highlighted on Blogger as an interesting site:

The Fanatic Cook at http://fanaticcook.blogspot.com/

I was thoroughly impressed with the insightful and entertaining commentary. I'd highly recommend this site to you for reading on nutrition. In particular, her coenzyme Q10 column was exceptionally well written and clear.(http://fanaticcook.blogspot.com/2005/02/statins-and-not-well-publicized-side.html)

Also read her column, Super NonFoods at http://fanaticcook.blogspot.com/2005/07/super-nonfoods.html.

There's also oodles of recipes, all for the taking.

Eggs have been in the center of the cholesterol controversy almost from the very start.

The traditional argument against eggs went that eggs, high in cholesterol (210-275 mg per egg)and with some saturated fat (1.5-2.5 grams per egg), raised blood cholesterol (and LDL). Out went the daily fried, scrambled, poached eggs that many Americans indulged in most mornings. (We replaced it with more breakfast cereals and other carbohydrate conveniences, then got enormously overweight.)

A large Harvard epidemiologic study in 1999 called this observation into question. They tracked the fate of 117,000 thousand people and then compared the rate of heart attack, death, and other cardiovascular events among various people correlated to the "dose" of eggs they ate. Egg intake varied from none to 7 or more per week. Lo and behold, people who ate more eggs appeared to not suffer more events.

This study, large and well-conducted by an internationally respected group of investigators, seem to reopen the gates for more egg consumption, though most Americans still consume eggs cautiously.

Deeper down in this study, however, was another observation: People with diabetes who ate 1 egg per day had double the risk of heart attack. Because this study was observational, no specific conclusion as to why could be drawn.

A new study conducted by a Brazilian group may shed some light. Healthy (non-diabetic) men were fed an emulsion of several eggs. Inclusion of plentiful yolks caused a dramatic slowing of fat clearance from the blood. Specifically, "chylomicron remnants" were abnormally persistent in the blood. Chylomicron remnants are potent causes of coronary plaque. (Chylomicron remnants can be measured fairly well by intermediate-density lipoprotein and VLDL by NMR, or IDL by VAP.)

Diabetics are know to have substantial disorders of after-meal fat clearance, including an excess of chylomicron remnants. Could the Brazilian observation be the explanation for the increased event rate in diabetics in the Harvard study? Interesting to speculate.

We continue to tell our patients that eating eggs in moderation is probably safe. After all, there are good things in eggs: the high protein in the egg white, lecithin in the yolk. It is the yolk's contents that are in question, not the white. Thus, you and I can eat all the egg whites (e.g., Egg Beaters) we want. It's the safety of yolks that are uncertain.

The abnormal after-eating effect suggested by the Brazilians opens up some very interesting questions and confirms that we should still be cautious in our intake of egg yolks. One yolk per day is clearly too much. What is safe? The exisitng information would suggest that, if you have diabetes, pre-diabetes, or a postprandial disorder (IDL, VLDL), you should minimize your egg yolk use, perhaps no more than 3 or so per week, preferably not all at one but spaced out to avoid the after-eating effect.

Others without postprandial disorders may safely eat more, perhaps 5 per week, but also not all at one but spaced out.

Track Your Plaque Members: Be sure to read our upcoming Special Report on Postprandial Disorders. It contains lots of info on what this important pattern is all about. Postprandial disorders are largely unexplored territory that hold great promise for tools to inhibit coronary plaque growth and drop your heart scan score. The Brazilian study is just one of many future studies that are likely to be released in future about this very fascinating area.

If there's one thing I truly fear from a heart scan score reduction/coronary plaque regression standpoint, it's diabetes.

I saw a graphic illustration of this today. Roy came into the office after his 2nd heart scan. His first scan 14 months ago showed a score of 162. Roy started out weighing well over 300 lbs and with newly-diagnosed adult diabetes.

Roy put extraordinary effort into his program. He lost nearly 70 lbs by walking; cutting processed carbohydrates, greasy foods, and slashing overall calories. His lipoproteins, disastrous in the beginning, were falling into line, though HDL was still lagging in the low 40s, as Roy remains around 60 lbs overweight, even after the initial 70 lb loss.

Unfortunately, despite the huge loss in weight, Roy remains diabetic. On a drug called Actos, which enhances sensitivity to insulin, along with vitamin D to also enhance insulin response, his blood sugars remained in the overtly diabetic range.

Roy's repeat heart scan showed a score of 482--a tripling of his original score.

Obviously, major changes in Roy's program are going to be required to keep this rate of growth from continuing. But I tell Roy's story to illustrate the frightening power of diabetes to trigger coronary plaque growth.

Like Kryptonite to Superman (remember George Reeves crumbling and falling to his knees when the bad guys got a hold of some?), diabetes is the one thing I fear greatly when it comes to reducing your heart scan score. As you see with Roy's case, diabetes can be responsible for explosive plaque growth, more than anything else I know.

The best protection from diabetes is to never get it in the first place. (See my earlier Blog, "Diabetes is a choice you make".)

You can always count on Dr. John Cannell for unique perspectives on vitamin D. I reprint here his unfailingly entertaining and informative Vitamin D Newsletter on whether vitamin D replacement enhances physical performance.

The whole vitamin D "discovery" sometimes worries me. Vitamin D has proven to be an unbelievable, remarkable, dramatic boon to health, including facilitation in dropping CT heart scan scores. Yet the answer was always right in front of us. It worries me that you and I might have the answer to important questions right within our grasp all along--but don't know it. What if the same were true, say, for cancer? That is, a profound answer is right there, but our eyes just pass right over it.

Anyway, we should all keep our eyes open and perhaps you and I will continue to identify the most powerful tools available that return control over heart disease to us and take it away from the perverse, procedural hospital formula that still reigns.

Peak Athletic Performance and Vitamin D

"No way doc." I had just finished telling my patient about the benefits of vitamin D, telling him he should take 4,000 IU per day, using all the techniques I had learned in 30 years of medical practice to convince someone proper treatment is important. But, he knew the U.S. government said he only needed 200 IU per day, not 4,000. He also knew the official Upper Limit was 2,000 IU a day. "What are you trying to do doc, kill me?" I told him his 25(OH)-vitamin D blood test was low, only 13 ng/ml. He had read about that too, in a medical textbook, where it said normal levels are between 10 and 40 ng/ml. "I'm fine doc;" adding "Are you in the vitamin business?" I explained I was not; that the government used outdated values; that recent studies indicate ideal 25(OH)D levels are about 50 ng/ml; and that they indicated that he needed about 4,000 IU per day to get his level up to 50. "No thanks doc, I'm fine."

So I tried a different tact. I brought him copies of recent press articles. "Look," I said, "look at these." Science News called vitamin D the Antibiotic Vitamin. The Independent in England says vitamin D explains why people die from influenza in the winter, and not the summer. U.S. News and World Report says almost everyone needs more. Newsweek says it prevents cancer and helps fight infection. In four different recent reports, United Press International says that: it reduces falls in the elderly, many pregnant women are deficient , it reduces stress fractures, and that it helps heals wounds.

He glanced at the articles, showing a little interest in stress fractures. Then he told me what he was really thinking. "Look doc, all this stuff may be important to old guys like you. I'm 22. All I care about are girls and sports. When I get older, maybe I'll think about it. I'm too young to worry about it. I'm in great condition." I couldn't argue. He was in good health and a very good basketball player, playing several hours every day, always on indoor courts.

What could I do to open his eyes? As an African American, his risk of early death was very high, although the risk for blacks doesn't start to dramatically increase until their 40's and 50's. Like all young people, he saw himself as forever young. The U.S. government was no help, relying on a ten-year-old report from the Institute of Medicine that is full of misinformation.

I tired to tell him that the 200 IU per day the U.S. government recommends for 20-year-olds is to prevent bone disease, not to treat low vitamin D levels like his. I pointed out the U.S. government's official current Upper Limit of 2,000 IU/day is the same for a 300 pound adult as it is for a 25 pound toddler. That is, the government says it's safe for a one-year-old, 25-pound, child to take 2,000 IU per day but it's not safe for a 30-year old, 300-pound, adult to take 2,000 and one IU a day. I mean, whoever thought up these Upper Limits must have left their thinking caps at home. Nevertheless, nothing worked. My vitamin D deficient patient was not interested in taking any vitamin D.

What are young men interested in? I remembered that he had told me: "Sex and sports." Two years ago I had researched the medical literature looking for any evidence vitamin D enhanced sexual performance. Absolutely nothing. That would have been nice. Can you imagine the interest?

Then I remembered that several readers had written to ask me if vitamin D could possibly improve their athletic performance? They told me that after taking 2,000 to 5,000 IU per day for several months, they seemed just a little faster, a little stronger, maybe had a little better balance and timing. A pianist had written to tell me she even played a better piano, her fingers moved over the keys more effortlessly! Was vitamin D responsible for these subtle changes or was it a placebo effect? That is, did readers just think their athletic performance improved because they knew vitamin D was a steroid hormone precursor (hormone, from the Greek, meaning "to set in motion")?

The active form of vitamin D is a steroid (actually a seco-steroid) in the same way that testosterone is a steroid and vitamin D is a hormone in the same way that growth hormone is a hormone. Steroid hormones are substances made from cholesterol, which circulate in the body, and work at distant sites by "setting in motion" genetic protein transcription. That is, both vitamin D and testosterone regulate your genome, the stuff of life. While testosterone is a sex steroid hormone, vitamin D is a pleomorphic (multiple function) steroid hormone.

All of a sudden, it didn't seem so silly. Certainly steroids can improve athletic performance although they can be quite dangerous. In addition, few people are deficient in growth hormone or testosterone, so when athletes take sex steroids or growth hormone they are cheating, or doping. The case with vitamin D is quite different because natural vitamin D levels are about 50 ng/ml and, since almost no one has such levels, extra vitamin D is not doping, it's just good treatment. I decided to exhaustively research the medical literature on vitamin D and athletic performance. It took me over a year.

To my surprise, I discovered that there are five totally independent bodies of research that all converge on an inescapable conclusion: vitamin D will improve athletic performance in vitamin D deficient people (and that includes most people). Even more interesting is who published this literature, and when. Are you old enough to remember when the Germans and Russians won every Olympics in the 60's and 70's? Well, it turns out that the most convincing evidence that vitamin D improves athletic performance was published in old German and Russian medical literature.

With the help of my wife and mother-in-law, both of whom are Russian, and with the help of Marc Sorenson, whose book Solar Power is a must read, I finally was able to look at translations of much of the old Russian and German literature. When one combines that old literature with the modern English language literature on neuromuscular performance, the conclusion is inescapable. The readers who wrote me are right.

If you are vitamin D deficient, the medical literature indicates that the right amount of vitamin D will make you faster, stronger, improve your balance and timing, etc. How much it will improve your athletic ability depends on how deficient you are to begin with. How good an athlete you will be depends on your innate ability, training, and dedication. However, peak athletic performance also depends upon the neuromuscular cells in your body and brain having unfettered access to the steroid hormone, activated vitamin D. In addition, how much activated vitamin D is available to your brain, muscle, and nerves depends on having ideal levels of vitamin D in your blood - about 50 ng/ml, to be precise.

Why would I write about such a frivolous topic like peak athletic performance when cancer patients all across this land are dying vitamin D deficient? Like many vitamin D advocates, I have been disappointed that the medical profession and the public don't seem to care about vitamin D. Maybe people, like my young basketball player, will care if it makes better athletes. So, Hey! You jocks! Listen up! I'm talking speed, balance, choice reaction time, muscle mass, muscle strength, squats, reps, etc. Important stuff. Here's the Vitamin D Council's first ever sports quiz.

1. Vitamin D-producing UVB radiation improves athletic performance and may have been widely practiced by German and Russian Olympic athletes in the 1960's and 70's.

True. I found tantalizing evidence the Russians and especially the Germans were on to this during the 60's and 70's when those two nations took turns placing number one and number two in the Olympics every year?

For example, in 1938, Russian researchers reported that a course of ultraviolet irradiations improved speed in the 100-meter dash in college students compared to matched controls, both groups undergoing daily training. Average 100-meter dash times decreased from 13.51 seconds to 13.28 seconds in the non-irradiated controls, but from 13.63 seconds to 12.62 seconds in the irradiated students. Here we see training improved times but training and irradiation improved times much more. Obviously, irradiation or vitamin D would not render the same magnitude of improvements in world-class sprinters, but they would be happy with a few milliseconds.

Gorkin Z, Gorkin MJ, Teslenko NE. [The effect of ultraviolet irradiation upon training for 100m sprint.] The Journal of Physiology of the USSR [Fiziol, z. (RSSR)] 1938; 25: 695-701. (In Russian)

If you want to know what early German thinking was on this, read this summation of the German literature:

"It is a well-known fact that physical performance can be increased through ultra-violet irradiation. In 1927, a heated argument arose after the decision by the German Swimmers' Association to use the sunlamp as an artificial aid, constituting an athletic unfairness, doping, so to speak. In 1926, Rancken had already reported the improving effect of sunlamp irradiation on muscle work with the hand-dynamo-graph. Heib observed an improvement in swimming times after repeated irradiations. In thorough experiments, Backmund showed that a substantial increase in muscle activity happens after radiation of larger portions of the body with an artificial sunlamp; that this performance increase is not caused through local - direct or indirect - effects on the musculature, but through a general effect. This general effect, triggered by ultra-violet irradiation, is caused by a systemic effect on the nervous system." (p. 17)

Parade GW, Otto H. Die beeinflussung der leistungsfahigkeit durch Hohensonnenbestrahlung. Zeitschrift fur Klinische Medizin (Z Klin Med),1940;137:17-21 [In German]

In 1945, two Americans measured the cardiovascular fitness and muscular endurance of 11 male Illinois subjects undergoing training in an indoor physical education class, comparing them to 10 matched controls. Both groups underwent similar physical training. Treatment consisted of ultraviolet irradiation, given in the nude, up to two minutes per session, three times per week, for ten weeks in the late fall and winter. After ten weeks, the treatment group had a 19% standard score gain in cardiovascular fitness compare to a 2% improvement in the control students. To regular readers of this newsletter, it should come as no surprise that the un-irradiated control group reported twice as many viral respiratory infections as the treatment group.

Allen R, Cureton T. Effects of Ultraviolet Radiation on Physical Fitness. Arch Phys Med 1945: 10: 641-44.

In 1952, the German sports medicine researcher, Spellerberg, reported on the effects of wholesale irradiation of athletes studying and training at the Sports College of Cologne - including many elite athletes - with a "central sun lamp." He irradiated the athletes in their bathing suits, on both sides of their bodies, for up to ten minutes, twice a week, for 6 weeks. He reported a "convincing effect" on athletic performance and a 50% reduction in sports injuries. Results were particularly impressive for swimmers, soccer, handball, hockey, and tennis players, as well as for boxers and most track and field athletes. He reported that irradiation leading to burns, further irradiation of athletes having achieved peak performance, and irradiation within 24 hours of competition, all impaired athletic performance. Their results were so convincing, the Sports College of Cologne officially notified the "national German and International Olympic committee." (p. 570)

Spellerberg AE. [Increase of athletic effectiveness by systematic ultraviolet irradiation.] Strahlentherapie 1952; 88: 567-70. [In German]

In 1952, Ronge exposed 120 German schoolchildren to UV lights installed in classrooms and compared them to 120 un-irradiated control children. Over a two-year period - excluding summer vacations - he tested both groups with a series of six cardiovascular fitness tests using a bike ergometer. Un-irradiated children showed a distinct seasonality in fitness, with the highest values right after summer break and the lowest values in the spring. Treated children showed no seasonal differences in physical performance. Differences in work performance between the irradiated and un-irradiated children were most conspicuous in the spring with 56% difference between the two groups. In a final experiment, he gave 30 children in the control classrooms 6.25 mg (250,000 IU) of vitamin D as a single dose in February and found their performance had "increased considerably," one month later but did not report the actual numbers. He concluded that vitamin D, either as a supplement or induced via UV irradiation, improved physical performance.

In 1954, another researcher, at the Max-Planck Institute for Industrial Physiology in Dortmund, Germany, administered three different wavelengths of UV light over 8 weeks to university students. He found that ultraviolet light in the vitamin D-producing UVB range was consistently effective in reducing resting pulse, lowering the basal metabolic rate, and increasing athletic performance. UVA had no effect; interestingly, artificial UVC irradiation (the atmosphere normally completely filters out UVC radiation and thus it's not naturally present on earth) also gave some positive results.

In 1956, Hettinger and Seidel irradiated seven subjects in two different experiments: athletic performance on bike-ergometers and forearm muscle strength. They found that UV radiation induced a significant improvement in both muscle strength and athletic performance.

Another German researcher, at the Institute for Medical Physics and Biophysics at the University of Gottiingen, studied reaction times (the time needed to recognize a light and switch it off) during October and November in a series of controlled experiments on 16 children and an unspecified number of adults. He first controlled for practice effects (getting better by practicing) and then administered nine full-body UV radiation treatments over three weeks to the two treatment groups, using placebo radiation in the two control groups. UV radiation improved choice reaction time by 25% in children and 20% in adults while reaction time worsened in controls. The improvements in the irradiated groups peaked at the end of the three weeks of UV treatments and reverted to baseline levels three weeks later. In the two control groups, he found distinctly improved reaction times in the sunnier months.

The next study threw me because it was very well conducted, meticulously designed, and completely negative. In 1963, Berven reported on the effects of ultraviolet irradiation and vitamin D supplementation in a group of 30 Stockholm schoolchildren, aged 10 -11, comparing them to appropriate controls. He found no seasonality of fitness in the control group and no effect from either irradiation or two different vitamin D supplementation protocols (1500 IU of cholecalciferol daily for two months and a single dose of 400,000 IU of ergocalciferol) on performance on a bike ergometer.

Berven H. The physical working capacity of healthy children; seasonal variations and effect of ultraviolet irradiation and vitamin-D supply. Acta paediatrica. Supplementum 1963; 148: 1-22.

However, two things were not right and got me thinking. One, Berven found no seasonality of physical fitness and was the only author who found no such seasonal variations in athletic performance. Second, he found no effect from irradiation, again, the only author. Then I realized he was working with Swedish children in the late 1950's. Supplementation of children with high doses of vitamin D - often as cod liver oil - was routine in Scandinavia in the past, particularly in children. For example, in neighboring Finland, the official recommended daily dose of vitamin D for children - including infants - was 4,000 IU per day until 1964, when authorities reduced it to 2,000 IU/day. (That's right, you read that correctly, 4,000 IU per day for infants, which is too much by the way.)

In 1975, Finnish authorities reduced it to 1,000 IU per day, and, in 1992, to 400 IU per day. I emailed Professor Elina Hypponen who confirmed that the Swedish recommendations were similar to the Finnish ones. Therefore, it seems highly unlikely that many of Berven's Swedish children, studied in 1958 and 1959, all from "families with a good standard of living," were vitamin D deficient. Therefore, this study showed that vitamin D will not improve athletic ability in vitamin D replete people. That's very important because it indicates more is not necessarily better. More is only better if you are not taking enough.

Hypponen E, et al. Intake of vitamin D and risk of type 1 diabetes: a birth-cohort study. Lancet. 2001 Nov 3;358(9292):1500-3.

In the 1960's, three American researchers conducted experiments with university students. Rosentswieg studied the effects of a single six-minute dose of UV light on each side of the trunk in 23 college women, recording changes in various tests of muscle strength at one and five hours. He found a trend towards significance after five hours in white but not African American students. In 1968, Cheatum found that a six-minute administration of UV light, on each side of the trunk, increased the speed of 15 college women in the 30-yard dash. In 1969, Rosentswieg found a six-minute dose of UV light, on each side of the trunk, finding improved performance on a bicycle ergometer in college women. However, unlike the Germans and Russians, I could find no evidence that any of these American findings interested any American professionals involved in the care or training of athletes.

2. Athletic performance peaks in the summer when vitamin D levels peak, and is at its lowest in the winter when vitamin D levels are at their lowest.

A. True
B. False

True. The studies below - all I could find in the literature - show tests of physical performance peak in the summer, when vitamin D levels peak, start to decline in early autumn, as vitamin D levels decline, and athletic performance reaches its lowest point in late winter, when vitamin D levels bottom out. However, it is reasonable to assume that any associations between athletic performance and summer season may be due to "reverse causation." That is, improved athletic performance in the summer might be secondary to increased outdoor physical and recreational activity in the warmer weather with an indoor sedentary lifestyle during the colder months. Maybe people have better athletic ability in the summer because they exercise more. If that is true - and using the same logic - athletic performance should not begin to decline until late autumn, because at most temperate latitudes early fall weather is ideal for outdoor physical activities.

However, some of the studies below controlled for seasonal variations in time spent exercising. Furthermore, besides a consistent positive association of summer season with improved athletic performance, the below studies found an abrupt - and unexplained - reduction in athletic performance beginning in the early fall - when vitamin D levels decline - but when the weather is ideal for outdoor activities.

For example, in 1956, German researchers found a distinct seasonal variation in the trainability of musculature, studying wrist flexor strength in 21 German subjects undergoing daily training. They found highly significant seasonal differences with peak performance during the later part of the summer, nadirs in the winter, and an unexplained sharp autumn decline beginning in October.

Hettinger T, Muller EA. Seasonal course of trainability of musculature. Int Z Angew Physiol. 1956;16(2):90-4.

A study of Polish pilots and crew found physical fitness and tolerance to hypoxia were highest in the late summer with an unexplained sharp decline starting in September. The authors hypothesized that seasonal variations in an unidentified hormone best explained their results.

Kwarecki K, Golec L, Klossowski M, Zuzewicz K. Circannual rhythms of physical fitness and tolerance of hypoxic hypoxia. Acta Physiol Pol. 1981 Nov-Dec;32(6):629-36.

Cumulative work ability among 1,835 mainly sedentary Norwegian men during bicycle exercise tests showed an August peak, a sharp decline starting in the autumn, and a wintertime nadir. There were no seasonal changes in body weights, as might be expected if more caloric-demanding recreational activity during the sunnier months explained their results.

Erikssen J, Rodahl K. Seasonal variation in work performance and heart rate response to exercise. A study of 1,835 middle-aged men. Eur J Appl Physiol Occup Physiol. 1979 Oct;42(2):133-40.

Koch and Raschka reviewed the mostly German literature on the seasonality of physical performance, discussing studies indicating that muscle strength and stamina peak in the late summer. The authors then attempted to control for seasonal variations in the time spent exercising by instituting a controlled yearlong training regimen, beginning in December. The training regimen consisted of at least 20 push-ups per day and 2 or 3 long-distances races per week for the entire year. They found the both the number of push-ups and muscle strength peaked in late summer followed by a rapid decline in the fall, and a nadir in the winter, despite continued training. They concluded that seasonal variations in an unidentified hormone best explained their results. In addition, by now we all know that vitamin D is a seasonal hormone, and a steroid hormone precursor to boot.

3. Vitamin D has direct muscle-building (anabolic) effects.

A. True
B. False

True, but only in vitamin D deficient subjects. Both animal and human studies have found that vitamin D directly affects muscle. That is, vitamin D increases muscle mass.

For example, Birge and Haddad found that vitamin D caused new protein synthesis in rat muscle.

Birge SJ, Haddad JG. 25-hydroxycholecalciferol stimulation of muscle metabolism. J Clin Invest. 1975 Nov;56(5):1100-7.

What about humans? In 1981, Young performed muscle biopsies on 12 severely vitamin D deficient patients before and after vitamin D treatment. They found type-II (fast-twitch) muscle fibers were small before treatment and significantly enlarged after treatment. Sorensen performed muscle biopsies on eleven older patients with osteoporosis before and after treatment with vitamin D. The percentage and area of fast twitch fibers increased significantly after treatment, despite the lack of any physical training.

Sorensen OH, Lund B, Saltin B, Lund B, Andersen RB, Hjorth L, Melsen F, Mosekilde L. Myopathy in bone loss of ageing: improvement by treatment with 1 alpha-hydroxycholecalciferol and calcium. Clin Sci (Lond). 1979 Feb;56(2):157-61.

Sato reported that two years of treatment with 1,000 IU of vitamin D per day significantly increased muscle strength, doubled the mean diameter, and tripled the percentage of fast-twitch muscle fibers, in the functional limbs of 48 severely vitamin D deficient elderly stroke patients. The placebo control group suffered declines in muscle strength, and in the size and percentage of fast-twitch muscle fibers.

Sato Y, Iwamoto J, Kanoko T, Satoh K. Low-Dose Vitamin D Prevents Muscular Atrophy and Reduces Falls and Hip Fractures in Women after Stroke: A Randomized Controlled Trial. Cerebrovasc Dis. 2005 Jul 27;20(3):187-192 [Epub ahead of print]

These studies clearly show that vitamin D when administered to vitamin D deficient people stimulates the growth and number of those muscle fibers critical to athletic ability, type-2, or "fast twitch," muscle fibers.

4. Many studies have found direct associations between physical performance and vitamin D levels. That is, the higher your vitamin D level, the better your athletic performance.

A. True
B. False

True. I found 13 positive studies of associations between vitamin D levels and various parameters of neuromuscular performance. However, they were all in old people. Of course, old people can be athletes too. Furthermore, age differences in physiology and pharmacology are quantitative, not qualitative. That is, what is true in old people will be true in young people, although the magnitude might be different. Higher vitamin D levels are associated with a wide variety of athletic performance but appear to have the strongest associations with balance, timing, and timed tests of physical performance.

The three largest studies had more than 7,000 elderly subjects. All found evidence of a vitamin D threshold of between 30 - 50 ng/ml, above which further improvements in athletic performance were not seen. Wicherts and her colleagues found a linear correlation between vitamin D and neuromuscular performance; scores were 78% better for those with vitamin D levels greater than 30 ng/ml compared to those with levels less than10 ng/ml.

Wicherts IS, et al. Vitamin D status predicts physical performance and its decline in older persons. J Clin Endocrinol Metab. 2007 Mar 6; [Epub ahead of print]

Professor Heike Bischoff-Ferrari, now in Switzerland, did the largest study. She and her colleagues found a strong positive correlation and suggestion of a U-shaped curve with athletic performance on one test peaking with vitamin D levels of 50 ng/ml but deteriorating at higher levels. It is interesting to speculate that levels around 50 ng/ml may be optimal for athletic performance as such levels are common in humans living in a "natural" state of sun-exposure, such as lifeguards or tropical farmers.

Bischoff HA, Stahelin HB, Urscheler N, Ehrsam R, Vonthein R, Perrig-Chiello P, Tyndall A, Theiler R. Muscle strength in the elderly: its relation to vitamin D metabolites. Arch Phys Med Rehabil. 1999 Jan;80(1):54-8.

Interestingly, all three studies that looked for an association between mental abilities and vitamin D levels found one. A fourth study, unrelated to athletic function, also found an association. The obvious explanation for these findings is that cognitively impaired patients do not go outdoors as often as higher functioning patients and thus have lower vitamin D levels. However, Dhesi found the association after excluding all but mildly demented patients, making such an explanation more difficult. Flicker and - more recently - Przybelski and Binkley, found the association after controlling for outdoor activities, raising the possibility that the association of vitamin D levels with cognitive abilities is casual. Both the vitamin D receptor and the enzyme necessary to activate vitamin D are present in a wide-variety of human brain tissue. If vitamin D deficiency impairs cognitive abilities, it is likely that such deficiencies will also impair the brain's ability to process the complex circuits needed for peak athletic performance.

Przybelski RJ, Binkley NC. Is vitamin D important for preserving cognition? A positive correlation of serum 25-hydroxyvitamin D concentration with cognitive function. Arch Biochem Biophys. 2007 Jan 8;

There can be no doubt that higher vitamin D levels are associated with improved athletic performance in the elderly. From what we know of physiology and pharmacology, the same associations should hold true in young people, including young athletes.

5. Numerous studies have found that vitamin D improves physical performance.

A. True
B. False.

True, but, again, most all the studies are in old persons, not young ones, and none of the studies are in world-class athletes. However, there is no medical reason why vitamin D would improve the athletic performance of vitamin D deficient old people but not vitamin D deficient young ones. Eleven studies found vitamin D improved physical performance, mainly on measures of balance and reaction time. The one study of younger subjects showed dramatic physical performance effects in 55 severely vitamin D deficient women.

In summary, five converging - but totally separate - lines of scientific evidence leave little doubt that vitamin D improves athletic performance. (I actually left out a sixth line of evidence, something a little more complicated, studies of muscle strength and vitamin D receptor polymorphisms; the two studies I could find were both positive.) Anyway, the scientific evidence that UVB radiation, either from the sun or from sunbeds, will improve athletic performance is overwhelming and the mechanism is almost certainly vitamin D production. Peak athletic performance will probably occur with 25(OH)D levels of about 50 ng/ml, whether from sun, sunbeds, or supplements.

All that is missing is a big-time professional or college team identifying and then treating their elite athletes who are vitamin D deficient. Can you imagine what such performance-enhancing effects would do for basketball players, most of who are African American and who practice and play indoors all winter? Or gymnasts? Or weight lifters?

However, a word of caution. The above studies suggest that taking too much vitamin D (more than 5,000 IU per day) may actually worsen athletic performance. Take the right amount, not all you can swallow. Take enough to keep your 25(OH)D levels around 50 ng/ml, year round. Easier yet, regularly use the sun in the summer and sunbeds in the winter - with care not to burn. Once a week should be about right.

When you think about it, none of this should surprise anyone. Every body builder knows that steroid hormones can improve athletic performance, certainly increase muscle mass. Barry Bonds knows they increase timing and power. Moreover, activated vitamin D is as potent a steroid hormone as exists in the human body. However, unlike other steroids, levels of activated vitamin D in muscle and nerve tissue are primarily regulated by sun exposure. That's right, the rate-limiting step for the cellular function (autocrine) of activated vitamin D is under your control. It depends on how much you put in your both or go into the sun. It's ironic that many athletes now avoid the sun, organized baseball is even promoting sun avoidance and sunblocks. The ancient Greeks knew better; they had there elite athletes train on the beach and in the nude.

The medical literature indicates vitamin D levels of about 50 ng/ml are associated with peak athletic performance. Of course, recent studies show such levels are ideal for preventing cancer, diabetes, hypertension, influenza, multiple sclerosis, major depression, cognitive impairments, etc. But who cares about all that disease stuff old people get, we're talking about something really important: speed, balance, reaction time, muscle mass, muscle strength, squats, reps, etc. And guess who's now taking 4,000 IU/day? Yes he is, and he tells me his timing is better, he can jump a little higher, run a little faster, and the ball feels "sweeter," whatever that means.

The reason why I've been blogging lightly these past few days is because, as a favor, I'm covering the practice for some colleagues who I'm (very) loosely affiliated with. The time demands have been great.

Nonetheless, it is a good reminder to me just how far wrong conventional cardiology remains. Judging by what I see around me, there is a startling lack of restraint in proceeding to the catheterization laboratory. Curiously, the internists and family practitioners have been brainwashed into accepting this path. I suppose that all it takes is an occasional real "save" for these physicians to develop a fear of ever missing real disease.

What I'm seeing is just how many people presenting with chest pain or similar symptoms end up going to the cath lab. I would crudely estimate 80%. That is, once you make it past the emergency room, there's a four out of five chance that you'll end up with a heart catheterization to "be sure your heart is okay", "make certain you're not going to die of heart disease", "see if there's a ticking time bomb in your chest". You've heard all the clever, scary phrases that get tossed around to scare the pants off you and justify putting catheters in your groin.

Despite the fact that tools for heart disease prevention have improved dramatically, the volume of heart catheterizations continues to grow nationwide.

I find it shocking and unacceptable. We're currently working behind the scenes to help change this situation through education of the public. Persuade a $1 million a year cardiologist that he is overdoing procedures? Unlikely in my experience. Educate the public about the shocking over-reliance on high-revenue procedures? Perhaps more practical.

Garlic May Not Lower Cholesterol
Study Shows No Improvement in Cholesterol Levels From Raw Garlic or Garlic Supplements

Lots of reports continue to hit the press about a small study that hoped to determine whether garlic as whole cloves (4 to 6), an aqueous extract of garlic called Kyolic, or an oil extract called Garlicin (high in allicin), or placebo. No differences in lipid numbers including LDL cholesterol were observed.

(Full text at WebMD at http://www.webmd.com/cholesterol-management/news/20070226/garlic-may-not-lower-cholesterol?ecd=wnl_chl_030507. You may be required to log in or register.)

I believe that the researchers were sincere in their effort to follow an honest, scientfically sound clinical trial design. I'm personally not that surprised. The effect in prior studies has been modest, sometimes none. Does that mean that we should ignore the other studies that suggest there may be modest blood-thinning, anti-inflammatory, blood pressure-reducing, and cancer-preventing properties? No, it does not. Dr. Matt Budoff at UCLA even published a very small study in about 20 people that suggested a slowing of plaque growth by using Kyolic in persons tracked by CT heart scans.

Nonetheless, garlic is, at best, probably no more than a source of small benefits. The biggest fallout from this kind of report, however, is not the neutral results from garlic, but from the open door the drug companies sense when this happens.

If you read the WebMD report, you'll notice all sorts of advertisements from drug companies for statin cholesterol drugs ("Cholesterol health center"; "Understanding Cholesterol Numbers"; "There are two sources of cholesterol: food and family"), Niaspan (which I used to support but have been discouraged by the Kos companies excessively profiteering methods and recent big Wall Street sellout).

It doesn't follow. The failure of one nutritional strategy to reduce LDL does nothave to trigger a run to the drugs. Don't fall for it. Drugs have their place. So do supplements and food choices, which can be very powerful. Drug manufacturers and their marketing people salivate when something like this comes along, an open invitation to say, "If garlic doesn't work, _____ sure does."

Jason came to the office because of chest pain. At 34 years old, he works as manager of a (non-fast food) restaurant, but indulges in lots of the odds and ends. Among his indulgences: Diet Coke.

Every time he'd have a diet Coke, he'd have chest pain. Not drinking diet Coke--no chest pain. If Jason drank coffee, no chest pain. Other foods, no chest pain. Anyway, just eliminating the diet Coke seemed to do the trick. (Aspartame?)

Anyway, that's not why I tell you Jason's story. In the midst of his evaluation, an echocardiogram showed a mildly enlarged aorta, measuring 4.0 cm in diameter. So we obtained lipoproteins. Jason showed lipoprotein(a) and small LDL particles, the dreaded duo. We talked about how to correct this pattern. Among the strategies we discussed was niacin.

But what bothered me was that neither of Jason's parents had a diagnosis of heart disease. Jason had to have gotten Lp(a) from either his mother or father, since you obtain the gene from one or the other parent. You cannot acquire Lp(a). So one of Jason's parents was sitting on a genetic time bomb of unrecognized Lp(a) and hidden heart disease.

Because Jason's paternal grandfather had a heart attack at age 62, only Jason's Dad had the heart scan (though I urged both to get one). Score: 1483. Recall that heart scan scores >1000 carry a risk of death or heart attack of 25% per year if no preventive action is taken. Now, of course, we have to persuade Jason's Dad that a program of prevention--intensive prevention is in order, including a measure of Lp(a).

So that's the curious story of how Diet Coke probably saved Jason's Dad's life. The lesson is that if you or someone you know has Lp(a), think about their children as well as their parents, each of whom carry a 50% chance of having the pattern.

There's a widely-known (among cardiologists) problem with nuclear stress tests. It's called the "false positive." (Nuclear stress tests are known as stress Cardiolites, stress thalliums, stress Myoviews, persantine stress tests, adenosine stress tests)

Stress tests, nuclear and otherwise, are helpful for identifying areas of poor blood flow. If an area of poor blood flow is detected and the area is substantial, then there may be greater risk of heart attack and other undesirable events in the relatively near future.

What "false positive" means is a stress test that shows an abnormality but it's not true--it is falsely abnormal. There are a number of reasons why this can happen. The problem is that this phenomenon is very common. Up to 20% of nuclear stress tests are false positives.

There are indeed situations where there may an abnormality and it is not clear whether it is true or false. This may lead to a justifiable heart catheterization or CT coronary angiogram. But, given the extraordinary number of false positives, there's a lot of gray in interpreting these tests. Hospital staff, in fact, call nuclear medicine "unclear" medicine. It's common knowledge that you can often see just about anything you want to see on a nuclear image of the heart. Abnormalities in the bottom of the heart, the "inferior" wall, are especially common due to the overlap of the diaphragm with the heart muscle, yielding the appearance of reduced blood flow. Defects in the front of the heart heart are common in females with large breasts for the same reasons.

The problem: The uncertainty inherent in nuclear stress tests opens the door to the unscrupulous or lazy practitioner. Any blip, tick, or imperfection on the nuclear images serve as carte blanche to drag you into the hospital for procedures.

This abusive practice is, in my experience, shockingly common for two reasons: 1) It pays better to do heart catheterizations, and 2) Defensive medicine.

What's the disincentive? Only doing the right thing and maintaining a clear conscience. Slim reasons for many of my colleagues--and a lot less money.

If you are without symptoms and feel fine, and a nuclear stress test is advised by your doctor, followed by a discussion of an abnormality, insist on a discussion of exactly what is abnormal, just how abnormal, and what the alternatives might be. If you receive unsatisfactory or incomplete answers despite your best effort, it's time for another opinion.

Magnesium is kind of boring. So most people don't pay too much attention to it.

Magnesium can be important, however. I saw an interesting phenomenon recently. A type I diabetic patient of mine (that is, an adult who developed diabetes as a child), Mitch, was experiencing wide swings in blood sugar: low low's and very high high's (300-400 mg/dl). Mitch's magnesium was only marginally low at 2.0 mEq/L. (Ranges for normal magnesium blood levels are usually 1.3–2.1 mEq/L or 0.65–1.05 mmol/L.) Note that Mitch's blood levels fall within "normal." I do not agree with these "normal" ranges. I shoot for 2.1 to 2.4 mEq/L, which I think is the truly normal range.

In addition to eating plenty of raw nuts and green vegetables, Mitch began supplementing magnesium with magnesium citrate, 200 mg twice a day (our preferred supplement form). He reported that the wide swings in blood sugar were nearly eliminated.

Mitch's dramatic benefit is just a great illustration of how magnesium can help control blood sugar metabolism. A type I diabetic is more sensitive to the effects, but anyone with type II (adult) diabetes, metabolic syndrome, or just a slightly high blood sugar could benefit from magnesium supplementation.

There's a number of ways to accomplish getting sufficient magnesium in your daily regimen. Track Your Plaque members, Be sure to read:

It struck me recently that, for many people, it's not the second but the third heart scan that more commonly shows a reduction in score.

I think this is because many people's reaction to their first heart scan is "This can't be. There's no way my arteries have that much plaque." They then follow a half-hearted program to correct their patterns.

When the second heart scan shows a significantly higher score, that really catches their attention. This is when they finally buckle down and give it their all.

Only the occasional person will, after the first heart scan, seize full control and take their program very seriously. These tend to be highly motivated people.

Don't feel too bad if your second heart scan score shows an increase. Look at it for what it represents: feedback on the adequacy of your program.

Peter started out at age 59 at 248 lbs, standing 6 ft tall (BMI = 33.6!).

Along with his weight, Peter had the entire panel of phenemena of the so-called "metabolic syndrome", or pre-diabetes:

--Triglycerides 238 mg/dl and associated with extremes of excess VLDL and IDL
--High blood pressure
--Blood sugar 115 mg/dl
--High c-reactive protein
--Small LDL particles 99% of total LDL

Interestingly, Peter's HDL was a surprisingly favorable 58 mg/dl (HDL is usually low in this syndrome). However, when broken down by size, he had nearly zero large, healthy HDL (sometimes called HDL2b). Though total HDL was favorable, most of it was simply ineffective.

Peter eliminated snacks and processed foods, particularly bread; increased his reliance on healthy oils and lean proteins; incorporated soy protein; increased vegetables. He added 30 minutes of a rapid walk on a treadmill every day. He added vitamin D to achieve a blood level of 50 ng/dml. He added a magnesium supplement.

Peter has lost 31 lbs. in the last year. Weight 207 lbs., BMI 28.1 (desirable <25). Blood sugar: 96 mg/dl; triglycerides: 56 mg/dl; HDL 71 mg/dl with 35% in the large fraction; small LDL 45% of total. Not perfect, but a damn site better.

Control of metabolic syndrome is an achievable goal for over 90% of people, just with these simple efforts. We haven't yet had a chance to assess the effect on the progression or regression of Peter's heart scan score, but he has, at the very least, spared himself a future of diabetes and all its complications.

This is a "slice" from a normal heart scan in a 58 year old woman. Heart scan score zero. Look at the lungs, the dark areas left and right of the heart in the center. The lungs are also normal. Black represents normal density, healthy lung tissue. The white streaking is just normal lung blood vessels. This person doesn't smoke.

This woman smokes a pack of cigarettes a day and has done so for 45 years ("45 pack-years"). She had a surprisingly low heart scan score (at age 64) of only 71, despite the smoking. However, look at this woman's lungs. It's a little tough to make out, since the computer graphics loses some of the resolution. But you can see the near absence of lung tissue on both sides. This is an advanced phase of the destructive lung disease, emphysema, from smoking. Even if she quit smoking today, the destroyed lung tissue never grows back. She literally has huge gaps or holes in her lungs where lung tissue used to be.

Smoking is among the most destructive, terrible things you can do to your body, short of swallowing strychnine or jumping off a building. Stay as far the heck away from cigarettes as you possibly can. If you are exposed to "secondary" smoke, insist that the person never smoke in your presence. It's not the smell that destroys your lungs or causes coronary plaque (though it is indeed foul), it's the actual smoke.

Do you need to become a vegetarian in order to reduce your heart scan score?

No. Plain and simple. We’ve had many non-vegetarians drop their scores.

That said, are there still advantages to following a vegetarian diet, or some variation on the vegetarian theme?

Yes, there are. Let’s put aside the moral or religious arguments in favor of not eating animals—the need to eliminate killing animals for food, elimination of suffering common in modern livestock practices, Kosher considerations, etc. (Not that there aren’t real arguments here. Our focus for this conversation is not, however, the moral dilemma, but the health argument.)

Some of the most unhealthy people I’ve ever met, mostly males, are proud carnivores who boast of their prodigious capacities to eat meat. Unfortunately, it’s hard to tease out the ill-effects of excessive meat eating, since these same men also tend to be substantially overweight, smoke, drink excessively, and fail to get exercise unless their job is physically demanding. You know the type.

What advantages does a vegetarian obtain? A number of studies have suggested that the reduced saturated fat, reduced exposure to parasites, as well as reduced exposure to the antibiotics and hormones now used routinely in livestock-raising practices, do indeed provide benefits to the vegetarian. Thus, vegetarians tend to be substantially thinner, experience less bowel cancer, have less diabetes and heart disease, and live longer.

(If you are interested in reading or seeing more about just how inhumane modern livestock practices are, take a look at the video, "Meet Your Meat" at meat.org. Be sure not to view this after dinner.)

Of course, some of the disadvantages of eating animal products diminish when free-range livestock are eaten, i.e., livestock not raised in the inhumane cramped, filthy conditions of livestock factories, but in the open, grazing or rooting freely. These animals tend to have different fat compositions and taste different.

The advantages of vegetarianism, however, have blurred in recent years, since many so-called vegetarians have failed to maintain the distinction between naturally-occurring foods and processed foods. So, Ritz Crackers, Oreo cookies, whole wheat bread, and Raisin Bran fit into a vegetarian program, but they’re awful for your health. I’ll occasionally meet a self-proclaimed vegetarian who looks every bit as unhealthy as a conventionally eating American, that is, overweight, pre-diabetic person with a developing heart scan score.

So it is not necessary to be vegetarian to reduce your score. You might consider vegetarianism for other reasons, such as moral considerations, or to reduce your risk for cancer. But it is not necessary to drop your heart scan score. A non-processed food diet? Now that's is worth giving serious consideration.

It sounds like a word game, but is health the absence of disease?

In other words, if you're not sick, you must be well. If you don't have cancer, heart disease (overtly, that is, like angina and heart attack), the flu, diarrhea, fevers, pain someplace . . . well then, you must be well.

Of course, most of us would disagree. You can be quite unhealthy yet have no overt, explicit disease. Yet this is the philosophy followed in conventional medicine when it comes to many aspects of health.

With regards to heart disease, if you have no chest pain or breathlessness, you don't have heart disease. "Oh, all right, we'll perform a stress test to be sure." Track Your Plaque followers, as well as former President Bill Clinton, recognize the enormous pitfalls of this approach: It fails to identify the vast majority of hidden heart disease. In heart disease, the apparent lack of overt, sympatomatic "disease" does NOT equal the true absence of disease, even life-threatening.

How about nutritional supplements? Vitamin D is a perfect example. Blood levels of vitamin D of 10 ng/ml--profound deficiency--are common, yet people feel fine. Beneath the surface, blood sugar rises because of poor insulin response, hidden inflammatory responses are magnified, HDL is lower and triglycerides are higher, coronary plaque grows at an accelerated rate, colon cancer activity is heightened . . . Though you feel fine.

Can an abnormal "endothelial response" be present while you feel fine? You bet it can. This refers to the abnormal constrictive behavior of arteries that is present in many people who have hidden coronary plaque or risk for coronary plaque, but is entirely beneath consciousness.

How about a triglyceride level of 200 mg/dl, fatally high from the Track Your Plaque experience? (We aim for <60 mg/dl.) This is typical in people who follow the diets endorsed by agencies like the American Heart Association and the American Diabetes Association, organizations too eager to keep the money flowing from corporate sponsors and thereby offer us their advice based more on politics and less on health. Triglyceride levels of 200 mg/dl cause no symptoms.

At so many levels, the absence of disease is NOT the same as health. Health is something that is expressed by, yes, feeling good, but it's also measured by so many other factors hidden beneath the surface. An annual physical is one lame effort to address this aspect of "health." But it needs to go farther, much farther.

Heart scan, lipoprotein testing, vitamin D blood level--those are the basic requirements to go beyond the shortsighted practice of the conventional approach in the world of heart disease.

Take a look at the list of ingredients in Cocoa Puffs: corn, sugar, corn syrup--all high glycemic index foods.

In other words, Cocoa Puffs is the physiologic equivalent of pure table sugar. Sure, it comes packaged with this wacky bird and the back of the box usually has fun games and offers. There's also the clever, fast-paced TV commercials to remind you of how fun Cocoa Puffs can be.

What is the actual consequence of a breakfast of a food like Cocoa Puffs in a cup of skim milk? That's easy: A big surge in insulin and blood sugar (from the corn and sugar), a drop in HDL cholesterol, surge in triglycerides (from the sugar and sugar-equivalents), increase in small LDL. Beyond this, you raise blood pressure and experience an insatiable increase in appetite. Then you get fat.

Obviously, none of this is desirable. Then why does the American Heart Association allow its Heart CheckMark endorsement on the package?

The Heart Association is trapped in 1982. Low-fat was in, saturated fat was the sole enemy of heart disease.

In 1982, the evils of small LDL, for instance, were unappreciated. LDL cholesterol was LDL cholesterol--all of it was bad and saturated fats seem to raise LDL. But the story has evolved enormously since then: LDL is not all the same. Small LDL is among the principal culprits in heart disease, the same small LDL hugely magnified by Cocoa Puffs and other similar products that fill 70% of supermarket shelves.

The American Heart Association needs to get with the times. The conversation on healthy diets has progressed considerably. Yet garbage foods that wreak havoc on health like Cocoa Puffs continue to be endorsed by an organization that still carries substantial clout with the American consumer.

My advice: Until they change their tune, anything that carries the endorsement of the American Heart Association should be eliminated from your diet.

The latest analysis of the data from Treat to New Targets (TNT) Trial shows that higher HDL cholesterol values are associated with reduced risk of heart attack, even in those with low LDL cholesterol values.

This counters the argument that some have made that, if a person takes a statin drug, raising HDL adds no additional benefit.

In the 9770-participant trial (randomized, double-blind), participants were given atorvastatin (Lipitor®) 10 mg or 80 mg per day. The study was sponsored by Pfizer, the manufacturer of Lipitor®. All participants were survivors of heart attacks, significant coronary disease by heart catheterization, or had previously undergone coronary angioplasty, stent placement, or bypass surgery—a high-risk group.

At the third month of enrollment, lipid (cholesterol panel) values were obtained and used as the basis for analysis. Participants on 80 mg atorvastatin achieved an average LDL cholesterol (Friedewald) of 77 mg/dl; participants taking 10 mg achieved a level of 101 mg/dl. Using these values, 8.7% of participants taking the higher dose of drug experienced an event, compared to 10.9% on the lower dose (which the investigators called a 22% relative reduction).

However, when the groups were re-analyzed by HDL cholesterol levels, higher HDLs remained predictive of less heart attack and other events, with the group having the highest HDL of =55 mg/dl experiencing 25% less events. Most interestingly, this effect was upheld even in participants with very low LDL cholesterols of <70 mg/dl.

I'm always a bit leery of drug company-sponsored studies, especially ones in which virtually all the participants tolerated a drug like Lipitor 80 mg, a dose in my experience that is very poorly tolerated for more than a few months. (Muscle aches are, in my experience, inevitable. I do not even recommend this dose.) In other words, the data are, in that respect, too good to believe.

Anyway, despite my reservations about these big money studies, there was nothing to gain from the HDL observation. (Of course, at one time, there would have been, given Pfizer's efforts to commercialize the now-kaput torcetrapib, scrapped because of excess mortality in phase II trials.)

Thankfully, there's other data that likewise suggest that the higher the HDL, the better. Yet more validation for the Track Your Plaque lipid targets of LDL 60 mg/dl, triglycerides 60 mg/dl or less, HDL 60 mg/dl or greater.

My younger sister, aged 48 years (sorry, sis), called this morning.

"I'm going to my doctor today. What labs should I tell him to draw?" she asked.

"Why do you have to tell him? Can't you just ask him what he thinks should be drawn?"

"No," she said. "He just draws what I tell him to."

Maybe my sister is bossier than most. But I've heard this from many patients, as well. They go to their primary care physician and end up requesting this or that test. Sometimes their doctor complies. Often, they resist and refuse to do so.

I've heard many complaints from patients about doctors refusing to order even fairly benign tests like a vitamin D blood level or lipoproteins, even a C-reactive protein.

The number of these sorts of complaints seems to be growing. Ten years ago, it rarely happened. Today, I hear this nearly every day.

I think it is symptomatic of the growing discontent we all have with the status quo in healthcare. We are all expected to submit to the paternalistic, what-can-you-possibly-know mentality that still rules the day in medical offices. Only 40-50 years ago, if you wanted to look at a medical book, you'd have to ask the librarian for special permission so that they could make sure you weren't just a pervert trying to look at naked bodies. Today, every manner of medical and health information can be found online. Quite a contrast.

We are entering a new age, one in which people are far better informed, have surfed the internet and read media reports on health topics, have been exposed to drug company advertising, and know a fair amount about nutritional supplements. I think the system needs to change to accommodate this rapidly growing hyper-knowledgeable society.

In past, when a health problem turned up, you'd turn to your doctor first. I predict that,in the next few years, we will use the doctor as a place of last resort, the person we turn to when all else has failed, after you've exhausted your information sources.

I hope that the Track Your Plaque process will become one of the engines of change, an information resource that provides empowering tools that don't replace your doctor, but provide many information tools that are superior and may minimize your reliance on a health care provider.

I picked up a hospital publication today. Featured prominently on the cover was a glossy photo of an attorney and his wife, both smiling.

The headline: "Atorney grateful for the lifesaving work of the ______ Hospital."

The story detailed the near-tragic story of how this 59-year old man was exercising at his local gym, only to lose consciousness after stepping off one of the exercise machines. Bystanders--hospital employees, as luck would have it--checked the man's pulse: none. They performed CPR. Ambulance called, blah blah blah.

Severe coronary disease discovered, extensive atherosclerotic plaque in all three coronary arteries, a 12-inch chest incision later and he and his wife are eternally grateful for the fine work done at X hospital. And so they should be for a job well done.

But wait a minute. After the urgent hospital dust settled, did anyone ask the one crucial question: Why wasn't this man's far-advanced heart disease identified? Why did he have to die and be resuscitated before his disease was recognized?

If this man was an indigent, homeless alcoholic . . . well, perhaps it would be no surprise. Health is neglected in this population. But a successful attorney?

Detecting hidden coronary atherosclerotic plaque simply isn't that tough. In Milwaukee, $199 would have diagnosed his disease unequivocally.

Unfortunately, we still have to set off drumrolls and crash cymbals to even begin to get the attention of the practicing physicians around us who continue to fail to diagnose hidden coronary disease. I wouldn't be at all surprised to hear if this man had a $4000 nuclear stress recently that was normal. Why would a nuclear stress test be normal? Easy: Wrong test.

The hidden message: The failure to diagnose paid somebody and some hospital over $100,000. So, why bother detecting disease before the payoff?

The profit motive in all this is all too obvious. The only other explanation is the enormous, repetitive, and systematic stupidity of the conventional approach to heart disease detection. You have the solution, at least for you and the people around you, in a CT heart scan and in the Track Your Plaque program.

Dr. John Rumberger has, from its start, been a good friend of the Track Your Plaque program.

We are very proud to have his friendship. Dr. Rumberger is not only a world-renowned scientist in the world of cardiac imaging and heart scanning, but also a humanitarian and gentleman. From the very first day I met Dr. Rumberger many years ago, when he answered my many silly and naive questions about heart scans, I came to appreciate his deep and genuine interest in improving the world of heart disease detection.

I tracked Dr. Rumberger down from his busy schedule, now on a new project at the Princeton Longevity Center in Princeton, New Jersey.

TYP: Dr. Rumberger, we understand that your career has taken a new direction. Can you tell us about your current project?

Dr. Rumberger: I have not really taken a new direction, but further expanded on my opportunities.

I remain Medical Director of PrevaHealth Wellness Diagnostic Center (formerly Healthwise) in Columbus, Ohio. At that center, we see patients referred by their doctors for further refinement in cardiac risk stratification using heart and body scanning. However, by only doing scans alone there are limited opportunities for me to react in a meaningful way with the individual patients and thus I miss opportunities to do direct one-on-one teaching.

Currently, I spend most of my time in Princeton, NJ as Director of Cardiac Imaging for the Princeton Longevity Center. At the PLC, we perform comprehensive medical examinations along with screening CT scans, blood work, fitness and diet consultation to affect a more thorough one-on-one experience. Each patient then receives a comprehensive de-briefing.

In addition, since I have been involved with cardiac CT for now nearly 24 years, the PLC also affords me an opportunity to develop a CT coronary angiography training program for cardiologists and radiologists (www.cardiaccta.us). Together, these new efforts are merely an extension of my interests in prevention, patient care, and teaching.

TYP: Based on your book, The Way Diet, we understand that you advocate gravitating away from processed foods and incorporating more nuts, monounsaturated oils, lean proteins like fish, and a reduction in processed carbohydrates. You’ve also been a proponent of the Mediterranean diet that demonstrated a dramatic reduction in cardiovascular events in the Lyon Heart Study.

Has your philosophy or practice regarding nutritional strategies evolved or changed in any way since your book was published?

Dr. Rumberger: No, the strategies put forward in The Way Diet have, if anything, been reinforced by further and further research in selecting foods that are naturally high in anti-oxidants with lean sources of protein and reduced intake of processed sugar-containing preparations. The book, however, is what I call a ‘philosophy’ book which looks at three major aspects: proper diet, adequate exercise, and stress management. I also include some recipes which follow the dietary plans, but are done using ingredients that are commonly found in the average home.

TYP: We regard you as the source of much of the wisdom in heart scanning as the basis for early heart disease detection. Much of the original and subsequent scientific data, in fact, bears your name. Can you touch on some of the new directions your research has taken over the past couple of years?

Dr. Rumberger: We have come a long way from the beginning and there is a long way to go to get this incorporated into routine preventive care in the United States.

The most recent research has provided not so much more information as continuing to reinforce the old research. As I always say: if your research continues to show the same thing, then maybe there is a clear pattern here! The biggest challenge is getting this message into the mainstream and also trying to get cardiologists (and internists and, in fact, the general public) away from ‘stenosis’ detection to define the real cause of heart attacks (plaque) and into ‘plaque detection.’ This is where basic heart scanning has the greatest potential to reduce the expanding burden of heart disease.

You may be aware of our SHAPE initiave in which an international group of cardiologists and scientists have advocated getting a heart scan FIRST and then, if abnormal, checking your cholesterol values; rather than using cholesterol (which is valuable, but highly variable in predictive power) to determine who needs medications or further testing. The heart scan can define the current level of plaque and THEN you can determine what to do about it. [See the Track Your Plaque report on the release of the Shape Guidelines at SHAPE Guidelines]

TYP: We understand that you are performing CT coronary angiography in your center. What are your thoughts on the role of CTA in 1) screening for coronary disease, and 2) its role in the diagnostic process?

Dr. Rumberger: CT coronary angiography (CTA) is an incredible method to really define the extent of disease, beyond just coronary calcium. Its role is most appropriate in ruling OUT a significant ‘stenosis’ while really defining the absence or presence (and thus ‘how much’) of plaque. It is the ultimate ‘plaque detector’. CTA is best used in patients who have some symptoms, but in whom the clinician feels may NOT have clear cardiac chest pain. By risk-stratifying using CTA, we also gain information about heart size, heart function, whether there is prior heart damage, as well as other important information. This then becomes a very universal means to risk-stratifying individuals.

TYP: Thanks for your wonderful insights, Dr. Rumberger! We look forward to hearing about your future projects and research directions.

It's been a glorious summer in Wisconsin.

For weeks straight, we've enjoyed bright, sunny days with temperatures in the 70s and 80s. Even now, in late September, our windows are wide open and the days are warm and sunny. Yesterday, it was 84 degrees. Yes, it did rain for a stretch of about 10 days in August, but for the most part it has been a wonderfully sunny summer.

So it struck Andy as a big surprise when we checked his 25-OH-vitamin D3 blood level: 15 ng/ml--severe deficiency.

"I don't get it. I'm outside almost every day. Look at me! How do you think I got this tan?"

Indeed, Andy sported a nice dark tan over exposed areas.

In fact, Andy was among the dozen or so people this month with deficiencies of this magnitude.

Deficiency is not the exception; it is the rule. Of course, if Andy's blood level is at the level of severe deficiency in September, he will only trend lower over the next few weeks and months. He would likely have shown vitamin D blood levels of <10 ng/ml by January--profound deficiency.

With deficiency of this severity, Andy has been exposing himself to risk for prostate and colon cancer, diabetes and metabolic syndrome, low HDL, higher triglycerides, higher blood sugars, higher C-reactive protein, osteoporosis, arthritis . . .

Correcting the deficiency is easy. But, as you can see, getting sun is not always the answer. Even with an active, outdoor lifestyle and a tan, Andy still remained significantly deficient. Oral replacement with vitamin D3, or cholecalciferol, is an absolute necessity.

In general, I try to exhaust possibilities before resorting to the statin drugs. But we still do use them, both in general practice and the Track Your Plaque program.

There are indeed a number of ways to reduce, minimize, or eliminate the need for these drugs. For instance, if your LDL is 150 mg/dl but comprised of 90% small particles, then a reduction in wheat and other high-glycemic index foods, weight loss, fish oil, and niacin can yield big drops in LDL.

But sometimes we need them. Say LDL is 225 mg/dl and is a mix of large and small. Exercise, weight loss, niacin, oat bran, ground flaxseed, Benecol, etc. and LDL: 198 mg/dl. Alright, that's when statins may be unavoidable. There's also many people who are not as motivated as all of us trying to reverse heart disease. Some just want the easy way out. Statins do indeed provide that option in some people.

So in truth, we end up using these drugs fairly regularly. How common are muscle aches and fatigue? In my experience, they are universal . If taken long enough, or if high doses are used, muscle complaints are inevitable. Most of the time, thankfully, they're modest and often relieved with a change in drug or with coenzyme Q10 supplementation.

But there's more to statin side effects than muscle aches. Among the wacky effects that I have witnessed with statin drugs:

--Insomnia-especially with simvastatin (Zocor and Vytorin). Insomnia can be quite severe, in fact, with difficulty sleeping more than 3-4 hours a night.

--Bone aches--I don't know why this happens, unless it's somehow related to muscle aches. I've seen this with all the statins, but more commonly with Crestor.

--Memory impairment--a la Dr. Duane Graveline's wacky book, Lipitor: Thief of Memory. I've seen this with Lipitor, though it's uncommon, and less commonly with simvastatin (Zocor, Vytorin).

--Diarrhea--More common with Zetia and Vytorin (which contains Zetia), because of the inhibition of bile acid reabsorption.

--Migraine headaches--This I certainly do not understand, but the cause-effect relationship is undoubtedly true in an occasional person.

--Low libido--In men more than women, though it may be more due to men being more willing to admit to it.

--Increased appetite--Rare, though I've seen dramatic instances.

--Tinnitus--Ringing in the ears. I've only seen it with Lipitor and Zocor.

In their defense (and in general I am no defender of the drug manufacturers), most people do fine with statin drugs, though the majority do eventually require coenzyme Q10 in my experience. By the way, coenzyme Q10 can be an indispensable aid to help tolerate statin agents.

I'd love to hear about your wacky experiences.

I don't use this space to toot my horn (at least I don't too often), but we were looking at the listings of our viewers and members. I was surprised to learn that we now have Track Your Plaque followers in 15 different countries around the world!

We have members from Europe including England, Ireland, Switzerland, Belgium, and the Czech Republic. We have members from as far away as South Africa, Australia, India, Singapore, Thailand, and China.

I see the entire Track Your Plaque process as a grand experiment. Never before in history has a system of health been delivered via a communication medium like the web. The internet provides more interactivity than television, it's more fluid than a book, it's more dynamic and evolves more rapidly than a face-to-face interaction. While we cannot be hands-on over the internet, we can still deliver all the crucial information and, hopefully, the knowledge on how to get it done.

Track Your Plaque is part of an even grander experiment: The movement to shift control over health away from the medical system, doctors, and hospitals and back to individuals. When you think about it, the idea that "health" (more acurately sickness) should be managed by people and institutions (e.g., hospitals and insurance companies) outside of the individual is a 20th century concept. I predict that this notion will also become a relic of the 20th century.

Someday, we will look back and laugh at the folly of the 20th century style of paternalistic health care. Perhaps it was a necessary step in the sequence to transform health to a better system that returns control to the individual. But it's clearly time for a change.

Track Your Plaque is an example of the extraordinary power that can be taken by a lone individual with only minimal assistance of a health care provider. I see Track Your Plaque members who understand heart disease (at least the coronary disease aspect) far better than 95% of my cardiology colleagues, 100% of my internal medicine and family practice colleagues. Physicians maintain a role, but their role has shrunk and receded. They should be facilitators of success in health, educators, a resource to turn to when we need help. It's not that way today. It will be in 50 years.

But, right now, we can get started on this wonderfully self-empowering--liberating-- movement by participating in this global experiment known as Track Your Plaque, the program with the goofy name that has the potential to usurp and unravel this enormous institutionalized system of health care the world has created.

There's a heated debate being waged on the Heart Hawk Blog

Dr. Melissa Walton-Shirley authored an editorial entitled It Should Be the Right of All Americans to Have Primary Percutaneous-Based Intervention for Acute Coronary Syndrome .

Heart Hawk's response:

Dr. Walton-Shirley feels the best use of time, talent, and money is to build more cath labs and train more people in how to use them so that IF you have a heart attack, you stand a better chance of being pulled back from the brink of death. Unfortunately, you have to first let people get so sick that they are about to die. My position is to use those same resources to prevent such disasters from happening in the first place. Take your pick. You cannot spend the money twice.

I am no stranger to "direct angioplasty," meaning performing immediate coronary angioplasty (with stenting) for heart attack. Since 1990, I have personally performed hundreds, perhaps over a thousand of these procedures, particularly when I was younger and my practice was procedurally-focused. But, after a few years, I quickly recognized the futility of this approach. Yes, you might have aborted a heart attack ,perhaps even saved a life at the brink of death. But wouldn't it have been better to have prevented the entire episode in the first place?

In my mind, putting a cath lab on every corner, as Dr. Walton-Shirley suggests, is like having a fire truck on every street to prevent a house from burning down. It's an enormously expensive proposition that provides no incentive to prevent fires. Why not spend the money on preventing the fires?

Expanding access to cath lab procedures is putting the fox in the henhouse. Procedures yield money--big money--for hospitals and cardiologists. Guess what happens when you build facilities that exceed the need? Yes--the number of procedures grows, whether or not they were needed.

In my view, Dr. Shirley-Walton's opinions are symptomatic of the profit-driven, procedurally-focused quick-fixes that divert money that would be far better spent on effective dissemination of preventive practices.
