Wheat belly 23. July 2007 William Davis (31) You've heard of "beer bellies," the protuberant, sagging abdomen of someone who drinks excessive quantities of beer. How about "wheat belly"? That's the same protuberant, sagging abdomen that develops when you overindulge in processed wheat products like pretzels, crackers, breads, waffles, pancakes, breakfast cereals and pasta. (By the way, this image, borrowed from the wonderful people at Wikipedia, is that of a teenager, who supplied a photo of himself.) It represents the excessive visceral fat that laces the intestines and triggers a drop in HDL, rise in triglycerides, inflames small LDL particles, C-reactive protein, raises blood sugar, raises blood pressure, creates poor insulin responsiveness, etc. How common is it? Just look around you and you'll quickly recognize it in dozens or hundreds of people in the next few minutes. It's everywhere. Wheat bellies are created and propagated by the sea of mis-information that is delivered to your door every day by food manufacturers. It's the same campaign of mis-information that caused the wife of a patient of mine who was in the hospital (one of my rare hospitalizations) to balk in disbelief when I told her that her husband's 18 lb weight gain over the past 6 months was due to the Shredded Wheat Cereal for breakfast, turkey sandwiches for lunch, and whole wheat pasta for dinner. "But that's what they told us to eat after Dan left the hospital after his last stent!"Dan, at 260 lbs with a typical wheat belly, had small LDL, low HDL, high triglycerides, etc. I hold the food companies responsible for this state of affairs, selling foods that are clearly causing enormous weight gain nationwide. Unfortunately, the idiocy that emits from Nabisco, Kraft, and Post (AKA Philip Morris); General Mills; Kelloggs; and their kind is aided and abetted by organizations like the American Heart Association, with the AHA stamp of approval on Cocoa Puffs, Cookie Crisp Cereal, and Berry Kix; and the American Diabetes Association, whose number one corporate sponsor is Cadbury Schweppes, the biggest soft drink and candy manufacturer in the world. As I've said many times before, if you don't believe it, try this experiment: Eliminate all forms of Toggle navigation Home Blog Home Archive Join Now Log in I had a heart attack--and I don't know why! 25. October 2006 William Davis (0) Kevin came to my office for another opinion. A husband and father of two teenagers, Kevin had his first heart attack at age 39. Kevin received two stents to his right coronary artery. The entire process took place in a flurry with little explanation over 48 hours, start to finish.He smoked a pack of cigarettes a day, but the only history of heart disease in his family was his father, who, also a smoker, had his heart disease uncovered in his late 70s. His internist subsequently prescribed Zocor even though Kevin's LDL cholesterol was a relatively unimpressive 128 mg/dl. Kevin subsequently asked his cardiologist, "Where did I get the heart disease from?""Cigarettes. And genetics. You can quit the first. There's nothing you can do about the second." End of explanation. This left Kevin frightened and demoralized. If much of the cause of his heart disease couldn't be identified, why bother quitting smoking? Why not enjoy what time he had left?Kevin was understandably shocked when I told him that genetic causes were 1)identifiable, 2)quantifiable, and 3) correctable. Kevin's full lipoprotein analysis subsequently showed the most dire combination that commonly accounts for coronary disease in young people: Lp(a) with small LDL particles. This, along with smoking, fully accounted for this young father of two's heart disease. Along with starting Kevin on a new program for correction of his patterns, I also persuaded him to get a heart scan. What usefulness is a heart scan after the fact? Plenty. Even though Kevin's right coronary was no longer "scorable" because the steel in the stent obscured our measurements, the two remaining unstented arteries would still yield a score. This provides a baseline for future comparison. Even after a stent, Kevin could "track his plaque". Butter basics 24. October 2006 William Davis (3) There’s lot of confusion about butter, margarines, and their substitutes. Butter/margarine substitutes that avoid the negative aspects and provide modest health benefits are available, but I find that people confuse what's what. So here’s a brief primer. Butter--Avoid it. Plain and simple. Butter is a rich source of saturated fat. Of 11.5 grams total fat per tablespoon, 7.3 grams are saturated. It is not better than margarine, contrary to simple-minded reports from some media sources. Butter raises LDL cholesterol, raises blood pressure, and has been related to various cancers. Margarine--Not better than butter, arguably worse. Some argue that the trans-fatty acids, or hydrogenated oils, used to solidify vegetable oils to make margarine solid are worse than butter. In addition to the ill-effects of butter, margarine reduces HDL and raises cancer risk, perhaps even more than saturated fats. Hydrogenation yields a very unnatural structure that modifies cellular behavior of the sort that may promote the appearance of cancer cells. More recently, however, some of the major manufacturers, like Blue Bonnet, have produced soft spread products without hydrogenation. These are reasonable substitutes when used sparingly. Smart Balance--This is a product made with canola oil, a source of monounsaturates (the best oil source after omega-3s), but manufactured without hydrogenation and therefore has no trans-fats. It does have, in my view, a bit too much saturated fat (1.5 gm per tbsp. in the 37% Light Spread; 2.5 gm per tbsp in the 67% regular spread). This is a reasonable product to use in small quantities. There is also a Smart Balance Omega PLUS product that contains added flaxseed oil and sterol esters. I do not recommend this product because of the sterol content (see below). I also object to the manufacturers who label their products “rich in omega-3s” when they mean linolenic acid (in flaxseed), which is converted to a trivial quantity of omega-3s. Linolenic acid may pose unique benefits of its own, but it should not be listed as an omega-3 source. Benecol--This is a butter substitute that contains stanol esters, a substance that reduces total and LDL cholesterol. Two tablespoons a day reduces LDL around 20 mg/dl, more or less depending on your starting cholesterol. There’s a light and regular spread. The light contains 20 calories less per tablespoon but somewhat less monounsaturates, but the same LDL-reducing stanol esters. The manufacturer does hydrogenate the oils, yielding 0.5 mg trans-fats per tablespoon--a small drawback.Take Control--Similar to Benecol, but made with sterol esters. Take Control also reduces LDL cholesterol. However, data from several high-quality studies from Finland suggest that sterol esters may, in some people, be absorbed into the blood. This is potentially concerning. There is a rare disease called sitosterolemia that results in coronary disease in teenagers and young adults in their 20s from increased absorption of sterol esters. While you can’t acquire this genetic disease, some people have the capacity to absorb sterol esters from their intestines very efficiently. I find it very disturbing and I suggest that you stay away this product and other sterol-containing products like HeartWise orange juice and Smart Balance Omega PLUS until the issue is clarified and safety assured. Brummel and Brown--A blend of vegetable oils (soybean and partially hydrogenated soybean) with calories and fats reduced by blending in yogurt. This is an okay product. The hydrogenation yields trans-fats below the FDA required declaration limit of 1.0 mg. There’s also 1.0 mg each of saturated and monounsaturated fats. The calories are relatively low as a consequence of the added yogurt, only 45 calories per tablespoon. This makes the Brummel and Brown a reasonable choice. Other products are making their way out to supermarkets. Look for the type of oil used. Canola, olive, and flaxseed are the best. Also look for trans-fats and saturated fat content; both should be low, preferably <1.0 mg per tablespoon, ideally none. The best choice among the above products in my view is Benecol, though it’s also the most expensive. It will yield substantial drops in LDL cholesterol. All the products in our informal tastings taste a lot like butter, or at least as well as we can remember what butter tasted like! The key with all of these products is use in moderation, since they all provide between 45?80 calories per tablespoon. Let Dr. Friedewald rest in peace 24. October 2006 William Davis (1) In the 1960s, doctors struggled with the concept of cholesterol and its relationship to heart disease. It was becoming clear that higher levels of cholesterol were predictive of heart disease. It was also becoming clear that the low-density fraction of cholesterol, or LDL, was somewhat better than total cholesterol in predicting heart attack. Cholesterol was easily measurable in the 1960s. LDL was not. So, Dr. Friedewald, a noted lipid researcher at the National Institutes of Health, proposed an easy method to calculate LDL cholesterol from total choleseterol, HDL, and triglycerides:LDL cholesterol = Total cholesterol – HDL cholesterol – triglycerides/5This simple manipulation would put LDL cholesterols into the hands of the practicing physician and the American public. Dr. Friedewald recognized that this calculation only represented an approximation of LDL cholesterol and that it was thrown off, sometimes substantially, by any abnormal rise in triglycerides or reduction in HDL. But it served its purpose at an age when most doctors hadn’t even heard of cholesterol and the public was still sold on whole milk and “farm-fresh” butter, and Chesterfields were the cigarette choice of most doctors.The world has since changed. Most doctors have heard about cholesterol and, along with the public, have been drowned in drug company marketing for cholesterol-reducing drugs. Most people with some level of common sense and health awareness no longer use butter or whole milk, and no longer believe that the brand of cigarette you choose can be healthy. But we’re still using Dr. Friedewald’s original calculation for LDL cholesterol. When you get an LDL cholesterol from your clinic, doctor, or hospital, >99% of the time it is obtained using Dr. Friedewald’s calculation. Is it because there’s nothing better available? No, it’s not. There’s two reasons why your neighborhood primary care physician or cardiologist is still using this dinosaur of testing called LDL:1) The lag in science to practice is 20 years. Accept that most primary care doctors are 20 years behind the times on many issues, LDL cholesterol included.2) Insurance companies vigorously discourage testing beyond conventional lipids. The array of objections we get from insurance companies is mind-boggling. It would be funny if human life and finances weren’t at stake. These “new” tests are “experimental”, “unproven”, not endorsed by standard guidelines, not approved by some internal committee, or simply “We don’t know what this test is” ?we’ve heard them all. What are the tests that are superior to Dr. Friendewald’s calculated LDL? There are several, listed here in order of best to worst:1) LDL particle number--the value generated by NMR lipoprotein testing. This is the gold standard, most reliable test available, and the one I recommend. 2) Apoprotein B--More widely available even from conventional laboratories in hospitals. Not as accurate as NMR LDL particle number, but a pretty good choice. Apo B is the principal protein in LDL, VLDL, and IDL particles, and so it’s a better reflector of risk from all of these lipoprotein fractions, not just LDL. 3) “Direct” LDL--This is LDL that is actually measured. Unfortunately, it ignores the issues of LDL size and has some other pitfalls, but it’s still better than calculated LDL4) Non-HDL cholesterol--So-called because it incorporates all undesirable cholesterol-containing lipids except good HDL, thus “non-HDL”. This is another calculation, though better than LDL (because it sums up the risk from other apoprotein B-containing lipoproteins). Non-HDL is calculated from Total cholesterol – HDL. It’s therefore available from any standard lipid panel. It’s little used in everyday practice, however, because most people and their physicians find it confusing.5) Friedewald calculated LDL--You can see that calculated LDL is last on a list of choices. Yet this is the measure that doctors use day in, day out. It’s the measure that drug companies base billions of dollars of revenue and profits on. It’s an everyday occurrence in my office that calculated LDL is 89 mg/dl, but the real value is somewhere between 160 and 200 mg/dl. That’s a big difference. Imagine your realtor tells you your house’s estimated value is $200,000 and that’s what you sell it for to an eager buyer. After closing, you find out your house was really worth $300,000. You’d be upset. But that’s what you’re often getting with LDL cholesterol?a bum deal. It’s part of the reason people will say, “My doctor said my cholesterol was fine and that no cause for my heart disease can be found. He said it was genetic.” In reality, they could have sky-high LDL cholesterol revealed by LDL particle number or apoprotein B. Use LDL cholesterol in a pinch when you’ve got nothing else. It’s also helpful to gauge any treatment effect of diet, functional foods, drugs, etc. But it is a seriously flawed tool to diagnose your initial level of risk. The key to losing weight 23. October 2006 William Davis (0) I saw three people this past week, all of whom set off on an effort to lose substantial quantities of weight. And all seriously needed to. All three started with at least 70 lbs. excess weight; all showed substantial weight-sensitive lipoprotein patterns like low HDL, small LDL, high triglycerides, VLDL, and pre-diabetic levels of blood sugar. They also all shared high blood pressure. All three also had high heart scan scores. Kate’s score was just over 1200. Tom, a 58-year old real estate developer, had a score of nearly 600. Susan, the youngest of the three at 52, had a heart scan score of 377¾99th percentile at this age. Losing weight was an absolute requirement for their plaque control program. Because their lipoprotein abnormalities and pre-diabetic patterns were triggered by weight, weight loss would provide powerful correction. Each and every one of them would need to lose much of their excess weight¾at least 50 lbs¾if they hoped to halt the relentless progression of their heart scan scores. All three of them returned after 6-8 weeks, and all had lost between 17-24 lbs: spectacular results. There’s no secret to weight loss. Each of them achieved their weight loss in slightly different ways. But they also shared several critical ingredients in their weight-loss efforts:1) All three dramatically slashed their intake of wheat flour-containing foods and other processed carbohydrates and did so consistently. All also avoided the usual high-fat, high caloric-density foods like butter, margarine, fried foods, greasy foods, nuts roasted in oil, etc. They concentrated on vegetables, salads, raw nuts, lean proteins (inc. turkey, chicken, fish, lean red meats, low-fat cottage cheese and yogurt). 2) They stopped using food as a reward or as a consolation tool. 3) Exercise for one hour a day at least 5 days a week. The exercise in 2 of 3 of these people was just walking. It wasn’t strenuous, it wasn’t expensive. The women both liked walking with friends or their spouse. Tom followed a more common male path of more strenuous work on his treadmill, elliptical, and biking at the fitness club. But they all did it religiously and missed rare sessions.4) They refrained from any and all alcoholic beverages. Yes, there are some advantages to 1-2 glasses of wine per day, but it stalls weight loss efforts. 5) They didn’t allow themselves any major indiscretions. There were no binges, major pig-outs at weddings, barbecues, or all-you-can-eat buffets. They did allow themselves an occasional “treat” but did so in small portions. That’s it. But for most people, that’s simply too much. Adhering to an effort to lose dramatic weight requires day-after-day consistency. Nobody can lose the equivalent of 70,000 calories (20 lbs.) just by skipping a meal, a 20-minute walk, skipping the mashed potatoes at dinner. It can be done. You’ve just got to be consistent about it. How can I get my lipoproteins tested? ass="post-title"> Heavy traffic and heart scans 17. July 2007 William Davis (4) A German study just reported in Circulation showed a graded response of EBT heart scan scores and proximity to traffic. Living 50 meters (around 150 feet) from traffic increased the likelihood of a higher coronary calcium score by 63% compared to those living 200 meters (around 600 feet or two football fields) away from traffic.A sample news story can be found at http://healthday.com/Article.asp?AID=606431. The German investigators speculated that either the heightened exposure to exhaust fumes and/or the increased stress triggered by the constant noise might be the culprits behind the phenomenon. I think the study is interesting in a number of ways from the Track Your Plaque viewpoint:--Sometimes, there are factors that extend beyond lipoproteins, vitamin D restoration, optimism vs. pessimism, etc. that influence heart scan scoring. Are these factors powerful enough to overcome the adverse effects of traffic or other environmental effects? Can your proximity to traffic make or break your heart scan score-controlling efforts? This remains to be established. --How much of a role does the stress issue play? Is this just a variation of the optimism vs. pessimism theme? I know when I'm in traffic in a car or on a bicycle, it often feels like I am at the mercy of hordes of people in a hurry, the soccer Moms on cell phones, applying makeup and eating, the hormonal teenager, the occasional drunk. Living in the midst of it must be demoralizing, a sense that you are lost in a sea of uncaring humanity stripped of individuality. When I look outside my den window right now, I see the lawn that I cut and water and the flowers and evergreen trees I've planted over the years. It provides a sense of life, belonging, and earth. What if instead I saw anonymous cars buzzing by, dozens of unfamiliar faces every minute, none of which plays any palpable role in my life? --This simple observation will add to the healthy-consciousness and Green movements, since it is just one more piece of evidence that congestion and urbanization do indeed take their toll. In an obtuse way, I think this is one step closer to increasing disillusionment over the "over-processing" of human experience: processed foods, depersonalization and alienation in neighborhoods and homes, the dissolution of the American family. Lastly, notice how the conversation about CT (in this case, EBT) heart scanning has seamlessly worked its way into conversation? Just ten years ago, a long-winded explanation would have been required in press reports on just what CT heart scanning was. Now, the information is presented and--well, we all know what heart scanning is, right? A small study but one that comes at an important time. Good things will come from this one study. It will work its way into discussions about where to locate schools, how to situate homes in relation to heavy traffic, it will help "legitimize" this wonderful tool called heart scanning. How many medical tests beyond blood work can be easily performed in 4500 study participants? I always like to take some simple observation and see how it fits into developing trends. Few studies or other human-generated experiences by themselves change the world. Instead, it happens in little incremental bits and pieces. Digging for the truth 15. July 2007 William Davis (9) I remain continually amazed how difficult it can be to gain an understanding of what is true and what is not true. I am particularly worried about the messages provided by agencies that stand to make enormous gains by persuading us to believe their version of the "truth". For a moment, let's strip away the charitable covers of some financially-motivated organizations and see what they really look like:Hospitals: The dream of hospitals is to shift the proportion of patients towards those with the most profitable diseases in well-insured patients. Heart disease is among the best paying diseases. HOSPITALS WANT YOU TO HAVE HEART DISEASE. Doctors: Many (though not all) want to deal with diseases that pay well. Implanting a stent can pay several thousand dollars. Putting in a defibrillator can likewise pay handsomely, even better than stents. DOCTORS WANT TO STEER YOU TOWARDS PROCEDURES THAT REIMBURSE GENEROUSLY. Talk is cheap and pays poorly. Heart scans? Useless, since they're cheap. CT angiography? Now we're talking! $1800 dollars is a lot more interesting than $200 or so for a simple heart scan. CT angiograms also lead to catheterization, stents, hospitalizations. Drug manufacturers: The holy grail for drug manufacturers is a chronic condition that is present in large numbers of people. An antibiotic, for instance, is a drug manufacturers waste of time: Short courses of treatment in relatively few people. Cholesterol drugs, blood pressure drugs, drugs to modify personality or some aspect of behavior--these you take for years, decades, or a lifetime, and millions are persuaded they need them. DRUG COMPANIES WANT CHRONIC CONDITIONS (WHETHER OR NOT THEY'RE DISEASES) IN PEOPLE WHO SURVIVE FOR A LONG TIME, NOT SICK PEOPLE. Supplement manufacturers: What don't we need in the eyes of sellers of nutritional supplement? While a program like Track Your Plaque makes liberal use of supplements in a focused and, I believe, rational way, supplement sellers want you to take dozens or preparations of dubious value: milk thistle, hawthorne, ribose, hoodia, silymarin, hydroxycitric acid . . . Unlike the larger ambitions and bigger money of the pharmaceutical industry, the supplement industry is often driven by the momentary craze and the quick payoff. THE SUPPLEMENT INDUSTRY IS LOOKING FOR SUCKERS.Food manufacturers: The holy grail for the food industry are foods that have high markups, are convenient (e.g., eaten right out of the box or package), and are purchased repeatedly. Even better, if a health claim can be added, it can ride the current wave of the public's health consciousness. Thus, Cocoa Puffs can be labeled "Heart Healthy". How about foods that have addictive potential and virtually ensure repeat sales? Eat some and you want more within 2-4 hours! As nutritionist Marion Nestle says, the mantra of the foods industry is "Eat More". It is my firm conviction that the epidemic of obesity in the U.S. is not due to laziness, video games, and computers. It is the fault of food manufacturers. FOOD MANUFACTURERS WANT US FAT AND HUNGRY AND WANT US TO STAY THAT WAY. What pays better, a 110 lb vegetarian woman who shops at the farmer's market and buys locally produced foods, or the 260 lb glutenous and always-hungry woman who fills her supermarket shopping cart with 15 cents worth of flour and sugar priced at $4.59 (cleverly disguised as a healthy breakfast cereal), instant mixes, convenient meals, energy bars, and chips? Government agencies: User fees for the FDA paid by drug companies have caused the FDA to be beholden to drug company pressures. The USDA, charged with crafting the food pyramid, was created to support the farm industry and distributors of their products, not to disseminate public health. The food pyramid is the watered down end result of food industry lobbying and threats, not the scientific advice of nutritionists. GOVERNMENT AGENCIES SERVE INDUSTRY FIRST, THE PUBLIC SECOND. Health websites: Read popular websites like WebMD for information and the conversation quickly steers towards drugs. "Natural treatments for cholesterol" talks about reducing saturated fat and then gushes about the wonders of statin drugs. Guess where 80% of WebMD's revenues come from? Yup, the drug industry. The same goes for many magazines, TV shows, and other media. MEDIA IS OFTEN THE TOOL OF BIG INDUSTRY. I'm sounding like a conspiracy theorist. I don't believe that I am, but I am skeptical of the messages we often receive from the media, advertisements, news reports, websites, etc. It's left to you and me to use our judgment and decide what is truth and what is someone's version of a message crafted towards their hidden agenda. I am hoping that the real truth will grow through a wiki-like phenomena driven and supervised by a collective knowledge that we all contribute towards. That will happen, most likely, on the internet. Just as Wikipedia overtook the revered Encylopedia Britannica in the blink of an eye at far less cost yet with greater depth and equivalent accuracy, so will it happen in health information. I'm uncertain of the eventual form this health-wiki will take, but it will shatter many smug and deeply-entrenched powers that at present continue to profit from mis-information. A new Track Your Plaque record: 63% reduction 14. July 2007 William Davis (3) Stress can booby-trap the best efforts at reducing your CT heart scan score. But Amy, our newest Track Your Plaque record holder, defied the effects of an overwhelmingly life stress to drop her heart scan score from 117 to 43--an amazing 63% reduction. Amy beat our previous record holder, Neal, who achieved a 51% reduction. Though Neal had dropped his score from 339 to 161, a drop of 178 and more than Amy's 74 point drop, on a percentage basis Amy holds the record. I'm also especially gratified that a woman now holds our record. I'm uncertain why, but the ladies have been shy and the men remain the dominant and vocal participants in our program. Speak up, ladies!Amy's complete story can be found in our latest Track Your Plaque Newsletter to be released later this week, as well as an upcoming feature on the www.cureality.com website. (We've got to toot our horn about successes like this!) The Ornish diet made me fat 13. July 2007 William Davis (16) I got that kind of question today that tempts me to roll my eyes and say, "Not again!""If I want to reverse my heart scan score, should I do the Ornish diet?" You know, the one by Dr. Dean Ornish: Dr. Dean Ornish's Program for Reversal of Heart Disease. I personally followed the Ornish program way back in the early 1990s. I reduced fat intake of all sorts to <10% of calories; eliminated all fish and meats, vegetable oils, and nuts; ate vegetables and fruits; and upped my reliance on whole grains. I used many of his recipes. I exercised by running 5 miles per day. (Far more than I do now!) I avoided sweets like candies and fruit juices. What happened? I gained 31 lbs, going from 155 to 186 lbs (I'm 5 ft 8 inches tall), my abdomen developed that loose, fleshy look, hanging over my beltline. My HDL plummeted to 28 mg/dl, triglycerides skyrocketed to 336 mg/dl, and I developed a severe small LDL pattern. I experienced a mental fogginess every afternoon. I felt tired and crabby much of the time. I sometimes struggled to suppress an irrational anger and frustration over the silliest things. I required huge amounts of coffee just to function day to day. Hundreds of my patients suffered similar phenomena.Few of us wear bell-bottomed jeans, tie-dyed t-shirts, or say "groovy". Rowan and Martin's Laugh-in is an "oldie", it's no longer cool to hold your index and middle fingers up in the "V" sign of peace. Even Ladybird Johnson has passed.So should go the misadventures of the ultra low-fat diet, as articulated by Dr. Ornish. His day came and went. We learned from our mistakes. Now let's do something better.Keep your eyes open for the New Track Your Plaque Diet. Do lower heart scan scores grow faster? 11. July 2007 William Davis (0) If Mary's heart scan score increases from 2 to 4 in one year, it represents a 100% increase in score. If Jane's heart scan score increases from 1002 to 1004 over the same period, it represents <1% increase, even though the true growth is the same: 2 points. This quirk of arithmetic needs to be factored in whenever you and your doctor try to puzzle out the meaning of an increasing CT heart scan score. Lower numbers, particularly those <100, can grow at seemingly much faster rates if viewed by percent per year increase. If no effort is taken to stop the growth in your coronary plaque, then scores of 10, 20, 30, or the like can easily grow 50-100% per year. In contrast, scores of 1000, 1500, and 2000 tend to grow at "slower" rates of 20% or so per year without corrective efforts, even though the absolute growth may be substantial. (Obviously, this bit of confusion can be best eliminated by reducing your heart scan score, but it doesn't always work out that way.)If we were all adept at advanced math, we should probably rely on logarithmic measures of plaque increase, rather than percent increase. Or, you can just keep in mind that the rate of plaque growth must always be viewed in the context of the absolute score. Mr. Salazar: Check your Lp(a) 9. July 2007 William Davis (8) Marathon star Alberto Salazar was just released from the hospital following a heart attack and a heart catheterization that led to a stent. The MSNBC version of the report can be viewed at http://www.msnbc.msn.com/id/19653682/.At 48 years old and holder of several American records for marathon times, Salazar's story is eerily reminiscent of Jim Fixx, who died at age 52 after writing a bestselling book, The Complete Book of Running. Thankfully, Salazar's story has a happier ending. Fixx died at a time when prevention of heart disease was quite primitive. Lipoprotein analysis was not broadly available to the public, CT heart scans had not yet been invented. Even statin drugs were just a gleam in the pharmaceutical industry's eye. But not so with Salazar. This Cuban-born marathoner experienced his heart attack at at a time when enormously useful steps can be taken to 1) document the extent of disease with a CT heart scan (the presence of a stent just means that one artery can't be "scored"), and 2) identify the causes of his disease.I suspect that the fact that yet another marathoner in the limelight will once again prompt the (likely non-sensical) conversation about long-distance running and the increased risk of heart disease. Unfortunately, I fear that the real cause will be left unidentfied and untreated: Lipoprotein(a), or Lp(a).It's almost certain that Fixx had Lp(a), given the fact that his dad had a heart attack at age 35. Running simply postponed the untreated inevitable.I hope Mr. Salazar is surrounded by doctors who have his true interests in mind (not just procedural excitement) and ask the crucial question: Why? The answer is almost certain to be Lp(a). << Older posts Newer posts >> Newer posts12...818283848586878889...123124Older posts

Butter basics 24. October 2006 William Davis (3) There’s lot of confusion about butter, margarines, and their substitutes. Butter/margarine substitutes that avoid the negative aspects and provide modest health benefits are available, but I find that people confuse what's what. So here’s a brief primer. Butter--Avoid it. Plain and simple. Butter is a rich source of saturated fat. Of 11.5 grams total fat per tablespoon, 7.3 grams are saturated. It is not better than margarine, contrary to simple-minded reports from some media sources. Butter raises LDL cholesterol, raises blood pressure, and has been related to various cancers. Margarine--Not better than butter, arguably worse. Some argue that the trans-fatty acids, or hydrogenated oils, used to solidify vegetable oils to make margarine solid are worse than butter. In addition to the ill-effects of butter, margarine reduces HDL and raises cancer risk, perhaps even more than saturated fats. Hydrogenation yields a very unnatural structure that modifies cellular behavior of the sort that may promote the appearance of cancer cells. More recently, however, some of the major manufacturers, like Blue Bonnet, have produced soft spread products without hydrogenation. These are reasonable substitutes when used sparingly. Smart Balance--This is a product made with canola oil, a source of monounsaturates (the best oil source after omega-3s), but manufactured without hydrogenation and therefore has no trans-fats. It does have, in my view, a bit too much saturated fat (1.5 gm per tbsp. in the 37% Light Spread; 2.5 gm per tbsp in the 67% regular spread). This is a reasonable product to use in small quantities. There is also a Smart Balance Omega PLUS product that contains added flaxseed oil and sterol esters. I do not recommend this product because of the sterol content (see below). I also object to the manufacturers who label their products “rich in omega-3s” when they mean linolenic acid (in flaxseed), which is converted to a trivial quantity of omega-3s. Linolenic acid may pose unique benefits of its own, but it should not be listed as an omega-3 source. Benecol--This is a butter substitute that contains stanol esters, a substance that reduces total and LDL cholesterol. Two tablespoons a day reduces LDL around 20 mg/dl, more or less depending on your starting cholesterol. There’s a light and regular spread. The light contains 20 calories less per tablespoon but somewhat less monounsaturates, but the same LDL-reducing stanol esters. The manufacturer does hydrogenate the oils, yielding 0.5 mg trans-fats per tablespoon--a small drawback.Take Control--Similar to Benecol, but made with sterol esters. Take Control also reduces LDL cholesterol. However, data from several high-quality studies from Finland suggest that sterol esters may, in some people, be absorbed into the blood. This is potentially concerning. There is a rare disease called sitosterolemia that results in coronary disease in teenagers and young adults in their 20s from increased absorption of sterol esters. While you can’t acquire this genetic disease, some people have the capacity to absorb sterol esters from their intestines very efficiently. I find it very disturbing and I suggest that you stay away this product and other sterol-containing products like HeartWise orange juice and Smart Balance Omega PLUS until the issue is clarified and safety assured. Brummel and Brown--A blend of vegetable oils (soybean and partially hydrogenated soybean) with calories and fats reduced by blending in yogurt. This is an okay product. The hydrogenation yields trans-fats below the FDA required declaration limit of 1.0 mg. There’s also 1.0 mg each of saturated and monounsaturated fats. The calories are relatively low as a consequence of the added yogurt, only 45 calories per tablespoon. This makes the Brummel and Brown a reasonable choice. Other products are making their way out to supermarkets. Look for the type of oil used. Canola, olive, and flaxseed are the best. Also look for trans-fats and saturated fat content; both should be low, preferably <1.0 mg per tablespoon, ideally none. The best choice among the above products in my view is Benecol, though it’s also the most expensive. It will yield substantial drops in LDL cholesterol. All the products in our informal tastings taste a lot like butter, or at least as well as we can remember what butter tasted like! The key with all of these products is use in moderation, since they all provide between 45?80 calories per tablespoon.
Let Dr. Friedewald rest in peace 24. October 2006 William Davis (1) In the 1960s, doctors struggled with the concept of cholesterol and its relationship to heart disease. It was becoming clear that higher levels of cholesterol were predictive of heart disease. It was also becoming clear that the low-density fraction of cholesterol, or LDL, was somewhat better than total cholesterol in predicting heart attack. Cholesterol was easily measurable in the 1960s. LDL was not. So, Dr. Friedewald, a noted lipid researcher at the National Institutes of Health, proposed an easy method to calculate LDL cholesterol from total choleseterol, HDL, and triglycerides:LDL cholesterol = Total cholesterol – HDL cholesterol – triglycerides/5This simple manipulation would put LDL cholesterols into the hands of the practicing physician and the American public. Dr. Friedewald recognized that this calculation only represented an approximation of LDL cholesterol and that it was thrown off, sometimes substantially, by any abnormal rise in triglycerides or reduction in HDL. But it served its purpose at an age when most doctors hadn’t even heard of cholesterol and the public was still sold on whole milk and “farm-fresh” butter, and Chesterfields were the cigarette choice of most doctors.The world has since changed. Most doctors have heard about cholesterol and, along with the public, have been drowned in drug company marketing for cholesterol-reducing drugs. Most people with some level of common sense and health awareness no longer use butter or whole milk, and no longer believe that the brand of cigarette you choose can be healthy. But we’re still using Dr. Friedewald’s original calculation for LDL cholesterol. When you get an LDL cholesterol from your clinic, doctor, or hospital, >99% of the time it is obtained using Dr. Friedewald’s calculation. Is it because there’s nothing better available? No, it’s not. There’s two reasons why your neighborhood primary care physician or cardiologist is still using this dinosaur of testing called LDL:1) The lag in science to practice is 20 years. Accept that most primary care doctors are 20 years behind the times on many issues, LDL cholesterol included.2) Insurance companies vigorously discourage testing beyond conventional lipids. The array of objections we get from insurance companies is mind-boggling. It would be funny if human life and finances weren’t at stake. These “new” tests are “experimental”, “unproven”, not endorsed by standard guidelines, not approved by some internal committee, or simply “We don’t know what this test is” ?we’ve heard them all. What are the tests that are superior to Dr. Friendewald’s calculated LDL? There are several, listed here in order of best to worst:1) LDL particle number--the value generated by NMR lipoprotein testing. This is the gold standard, most reliable test available, and the one I recommend. 2) Apoprotein B--More widely available even from conventional laboratories in hospitals. Not as accurate as NMR LDL particle number, but a pretty good choice. Apo B is the principal protein in LDL, VLDL, and IDL particles, and so it’s a better reflector of risk from all of these lipoprotein fractions, not just LDL. 3) “Direct” LDL--This is LDL that is actually measured. Unfortunately, it ignores the issues of LDL size and has some other pitfalls, but it’s still better than calculated LDL4) Non-HDL cholesterol--So-called because it incorporates all undesirable cholesterol-containing lipids except good HDL, thus “non-HDL”. This is another calculation, though better than LDL (because it sums up the risk from other apoprotein B-containing lipoproteins). Non-HDL is calculated from Total cholesterol – HDL. It’s therefore available from any standard lipid panel. It’s little used in everyday practice, however, because most people and their physicians find it confusing.5) Friedewald calculated LDL--You can see that calculated LDL is last on a list of choices. Yet this is the measure that doctors use day in, day out. It’s the measure that drug companies base billions of dollars of revenue and profits on. It’s an everyday occurrence in my office that calculated LDL is 89 mg/dl, but the real value is somewhere between 160 and 200 mg/dl. That’s a big difference. Imagine your realtor tells you your house’s estimated value is $200,000 and that’s what you sell it for to an eager buyer. After closing, you find out your house was really worth $300,000. You’d be upset. But that’s what you’re often getting with LDL cholesterol?a bum deal. It’s part of the reason people will say, “My doctor said my cholesterol was fine and that no cause for my heart disease can be found. He said it was genetic.” In reality, they could have sky-high LDL cholesterol revealed by LDL particle number or apoprotein B. Use LDL cholesterol in a pinch when you’ve got nothing else. It’s also helpful to gauge any treatment effect of diet, functional foods, drugs, etc. But it is a seriously flawed tool to diagnose your initial level of risk.
The key to losing weight 23. October 2006 William Davis (0) I saw three people this past week, all of whom set off on an effort to lose substantial quantities of weight. And all seriously needed to. All three started with at least 70 lbs. excess weight; all showed substantial weight-sensitive lipoprotein patterns like low HDL, small LDL, high triglycerides, VLDL, and pre-diabetic levels of blood sugar. They also all shared high blood pressure. All three also had high heart scan scores. Kate’s score was just over 1200. Tom, a 58-year old real estate developer, had a score of nearly 600. Susan, the youngest of the three at 52, had a heart scan score of 377¾99th percentile at this age. Losing weight was an absolute requirement for their plaque control program. Because their lipoprotein abnormalities and pre-diabetic patterns were triggered by weight, weight loss would provide powerful correction. Each and every one of them would need to lose much of their excess weight¾at least 50 lbs¾if they hoped to halt the relentless progression of their heart scan scores. All three of them returned after 6-8 weeks, and all had lost between 17-24 lbs: spectacular results. There’s no secret to weight loss. Each of them achieved their weight loss in slightly different ways. But they also shared several critical ingredients in their weight-loss efforts:1) All three dramatically slashed their intake of wheat flour-containing foods and other processed carbohydrates and did so consistently. All also avoided the usual high-fat, high caloric-density foods like butter, margarine, fried foods, greasy foods, nuts roasted in oil, etc. They concentrated on vegetables, salads, raw nuts, lean proteins (inc. turkey, chicken, fish, lean red meats, low-fat cottage cheese and yogurt). 2) They stopped using food as a reward or as a consolation tool. 3) Exercise for one hour a day at least 5 days a week. The exercise in 2 of 3 of these people was just walking. It wasn’t strenuous, it wasn’t expensive. The women both liked walking with friends or their spouse. Tom followed a more common male path of more strenuous work on his treadmill, elliptical, and biking at the fitness club. But they all did it religiously and missed rare sessions.4) They refrained from any and all alcoholic beverages. Yes, there are some advantages to 1-2 glasses of wine per day, but it stalls weight loss efforts. 5) They didn’t allow themselves any major indiscretions. There were no binges, major pig-outs at weddings, barbecues, or all-you-can-eat buffets. They did allow themselves an occasional “treat” but did so in small portions. That’s it. But for most people, that’s simply too much. Adhering to an effort to lose dramatic weight requires day-after-day consistency. Nobody can lose the equivalent of 70,000 calories (20 lbs.) just by skipping a meal, a 20-minute walk, skipping the mashed potatoes at dinner. It can be done. You’ve just got to be consistent about it.
How can I get my lipoproteins tested? ass="post-title"> Heavy traffic and heart scans 17. July 2007 William Davis (4) A German study just reported in Circulation showed a graded response of EBT heart scan scores and proximity to traffic. Living 50 meters (around 150 feet) from traffic increased the likelihood of a higher coronary calcium score by 63% compared to those living 200 meters (around 600 feet or two football fields) away from traffic.A sample news story can be found at http://healthday.com/Article.asp?AID=606431. The German investigators speculated that either the heightened exposure to exhaust fumes and/or the increased stress triggered by the constant noise might be the culprits behind the phenomenon. I think the study is interesting in a number of ways from the Track Your Plaque viewpoint:--Sometimes, there are factors that extend beyond lipoproteins, vitamin D restoration, optimism vs. pessimism, etc. that influence heart scan scoring. Are these factors powerful enough to overcome the adverse effects of traffic or other environmental effects? Can your proximity to traffic make or break your heart scan score-controlling efforts? This remains to be established. --How much of a role does the stress issue play? Is this just a variation of the optimism vs. pessimism theme? I know when I'm in traffic in a car or on a bicycle, it often feels like I am at the mercy of hordes of people in a hurry, the soccer Moms on cell phones, applying makeup and eating, the hormonal teenager, the occasional drunk. Living in the midst of it must be demoralizing, a sense that you are lost in a sea of uncaring humanity stripped of individuality. When I look outside my den window right now, I see the lawn that I cut and water and the flowers and evergreen trees I've planted over the years. It provides a sense of life, belonging, and earth. What if instead I saw anonymous cars buzzing by, dozens of unfamiliar faces every minute, none of which plays any palpable role in my life? --This simple observation will add to the healthy-consciousness and Green movements, since it is just one more piece of evidence that congestion and urbanization do indeed take their toll. In an obtuse way, I think this is one step closer to increasing disillusionment over the "over-processing" of human experience: processed foods, depersonalization and alienation in neighborhoods and homes, the dissolution of the American family. Lastly, notice how the conversation about CT (in this case, EBT) heart scanning has seamlessly worked its way into conversation? Just ten years ago, a long-winded explanation would have been required in press reports on just what CT heart scanning was. Now, the information is presented and--well, we all know what heart scanning is, right? A small study but one that comes at an important time. Good things will come from this one study. It will work its way into discussions about where to locate schools, how to situate homes in relation to heavy traffic, it will help "legitimize" this wonderful tool called heart scanning. How many medical tests beyond blood work can be easily performed in 4500 study participants? I always like to take some simple observation and see how it fits into developing trends. Few studies or other human-generated experiences by themselves change the world. Instead, it happens in little incremental bits and pieces. Digging for the truth 15. July 2007 William Davis (9) I remain continually amazed how difficult it can be to gain an understanding of what is true and what is not true. I am particularly worried about the messages provided by agencies that stand to make enormous gains by persuading us to believe their version of the "truth". For a moment, let's strip away the charitable covers of some financially-motivated organizations and see what they really look like:Hospitals: The dream of hospitals is to shift the proportion of patients towards those with the most profitable diseases in well-insured patients. Heart disease is among the best paying diseases. HOSPITALS WANT YOU TO HAVE HEART DISEASE. Doctors: Many (though not all) want to deal with diseases that pay well. Implanting a stent can pay several thousand dollars. Putting in a defibrillator can likewise pay handsomely, even better than stents. DOCTORS WANT TO STEER YOU TOWARDS PROCEDURES THAT REIMBURSE GENEROUSLY. Talk is cheap and pays poorly. Heart scans? Useless, since they're cheap. CT angiography? Now we're talking! $1800 dollars is a lot more interesting than $200 or so for a simple heart scan. CT angiograms also lead to catheterization, stents, hospitalizations. Drug manufacturers: The holy grail for drug manufacturers is a chronic condition that is present in large numbers of people. An antibiotic, for instance, is a drug manufacturers waste of time: Short courses of treatment in relatively few people. Cholesterol drugs, blood pressure drugs, drugs to modify personality or some aspect of behavior--these you take for years, decades, or a lifetime, and millions are persuaded they need them. DRUG COMPANIES WANT CHRONIC CONDITIONS (WHETHER OR NOT THEY'RE DISEASES) IN PEOPLE WHO SURVIVE FOR A LONG TIME, NOT SICK PEOPLE. Supplement manufacturers: What don't we need in the eyes of sellers of nutritional supplement? While a program like Track Your Plaque makes liberal use of supplements in a focused and, I believe, rational way, supplement sellers want you to take dozens or preparations of dubious value: milk thistle, hawthorne, ribose, hoodia, silymarin, hydroxycitric acid . . . Unlike the larger ambitions and bigger money of the pharmaceutical industry, the supplement industry is often driven by the momentary craze and the quick payoff. THE SUPPLEMENT INDUSTRY IS LOOKING FOR SUCKERS.Food manufacturers: The holy grail for the food industry are foods that have high markups, are convenient (e.g., eaten right out of the box or package), and are purchased repeatedly. Even better, if a health claim can be added, it can ride the current wave of the public's health consciousness. Thus, Cocoa Puffs can be labeled "Heart Healthy". How about foods that have addictive potential and virtually ensure repeat sales? Eat some and you want more within 2-4 hours! As nutritionist Marion Nestle says, the mantra of the foods industry is "Eat More". It is my firm conviction that the epidemic of obesity in the U.S. is not due to laziness, video games, and computers. It is the fault of food manufacturers. FOOD MANUFACTURERS WANT US FAT AND HUNGRY AND WANT US TO STAY THAT WAY. What pays better, a 110 lb vegetarian woman who shops at the farmer's market and buys locally produced foods, or the 260 lb glutenous and always-hungry woman who fills her supermarket shopping cart with 15 cents worth of flour and sugar priced at $4.59 (cleverly disguised as a healthy breakfast cereal), instant mixes, convenient meals, energy bars, and chips? Government agencies: User fees for the FDA paid by drug companies have caused the FDA to be beholden to drug company pressures. The USDA, charged with crafting the food pyramid, was created to support the farm industry and distributors of their products, not to disseminate public health. The food pyramid is the watered down end result of food industry lobbying and threats, not the scientific advice of nutritionists. GOVERNMENT AGENCIES SERVE INDUSTRY FIRST, THE PUBLIC SECOND. Health websites: Read popular websites like WebMD for information and the conversation quickly steers towards drugs. "Natural treatments for cholesterol" talks about reducing saturated fat and then gushes about the wonders of statin drugs. Guess where 80% of WebMD's revenues come from? Yup, the drug industry. The same goes for many magazines, TV shows, and other media. MEDIA IS OFTEN THE TOOL OF BIG INDUSTRY. I'm sounding like a conspiracy theorist. I don't believe that I am, but I am skeptical of the messages we often receive from the media, advertisements, news reports, websites, etc. It's left to you and me to use our judgment and decide what is truth and what is someone's version of a message crafted towards their hidden agenda. I am hoping that the real truth will grow through a wiki-like phenomena driven and supervised by a collective knowledge that we all contribute towards. That will happen, most likely, on the internet. Just as Wikipedia overtook the revered Encylopedia Britannica in the blink of an eye at far less cost yet with greater depth and equivalent accuracy, so will it happen in health information. I'm uncertain of the eventual form this health-wiki will take, but it will shatter many smug and deeply-entrenched powers that at present continue to profit from mis-information. A new Track Your Plaque record: 63% reduction 14. July 2007 William Davis (3) Stress can booby-trap the best efforts at reducing your CT heart scan score. But Amy, our newest Track Your Plaque record holder, defied the effects of an overwhelmingly life stress to drop her heart scan score from 117 to 43--an amazing 63% reduction. Amy beat our previous record holder, Neal, who achieved a 51% reduction. Though Neal had dropped his score from 339 to 161, a drop of 178 and more than Amy's 74 point drop, on a percentage basis Amy holds the record. I'm also especially gratified that a woman now holds our record. I'm uncertain why, but the ladies have been shy and the men remain the dominant and vocal participants in our program. Speak up, ladies!Amy's complete story can be found in our latest Track Your Plaque Newsletter to be released later this week, as well as an upcoming feature on the www.cureality.com website. (We've got to toot our horn about successes like this!) The Ornish diet made me fat 13. July 2007 William Davis (16) I got that kind of question today that tempts me to roll my eyes and say, "Not again!""If I want to reverse my heart scan score, should I do the Ornish diet?" You know, the one by Dr. Dean Ornish: Dr. Dean Ornish's Program for Reversal of Heart Disease. I personally followed the Ornish program way back in the early 1990s. I reduced fat intake of all sorts to <10% of calories; eliminated all fish and meats, vegetable oils, and nuts; ate vegetables and fruits; and upped my reliance on whole grains. I used many of his recipes. I exercised by running 5 miles per day. (Far more than I do now!) I avoided sweets like candies and fruit juices. What happened? I gained 31 lbs, going from 155 to 186 lbs (I'm 5 ft 8 inches tall), my abdomen developed that loose, fleshy look, hanging over my beltline. My HDL plummeted to 28 mg/dl, triglycerides skyrocketed to 336 mg/dl, and I developed a severe small LDL pattern. I experienced a mental fogginess every afternoon. I felt tired and crabby much of the time. I sometimes struggled to suppress an irrational anger and frustration over the silliest things. I required huge amounts of coffee just to function day to day. Hundreds of my patients suffered similar phenomena.Few of us wear bell-bottomed jeans, tie-dyed t-shirts, or say "groovy". Rowan and Martin's Laugh-in is an "oldie", it's no longer cool to hold your index and middle fingers up in the "V" sign of peace. Even Ladybird Johnson has passed.So should go the misadventures of the ultra low-fat diet, as articulated by Dr. Ornish. His day came and went. We learned from our mistakes. Now let's do something better.Keep your eyes open for the New Track Your Plaque Diet. Do lower heart scan scores grow faster? 11. July 2007 William Davis (0) If Mary's heart scan score increases from 2 to 4 in one year, it represents a 100% increase in score. If Jane's heart scan score increases from 1002 to 1004 over the same period, it represents <1% increase, even though the true growth is the same: 2 points. This quirk of arithmetic needs to be factored in whenever you and your doctor try to puzzle out the meaning of an increasing CT heart scan score. Lower numbers, particularly those <100, can grow at seemingly much faster rates if viewed by percent per year increase. If no effort is taken to stop the growth in your coronary plaque, then scores of 10, 20, 30, or the like can easily grow 50-100% per year. In contrast, scores of 1000, 1500, and 2000 tend to grow at "slower" rates of 20% or so per year without corrective efforts, even though the absolute growth may be substantial. (Obviously, this bit of confusion can be best eliminated by reducing your heart scan score, but it doesn't always work out that way.)If we were all adept at advanced math, we should probably rely on logarithmic measures of plaque increase, rather than percent increase. Or, you can just keep in mind that the rate of plaque growth must always be viewed in the context of the absolute score. Mr. Salazar: Check your Lp(a) 9. July 2007 William Davis (8) Marathon star Alberto Salazar was just released from the hospital following a heart attack and a heart catheterization that led to a stent. The MSNBC version of the report can be viewed at http://www.msnbc.msn.com/id/19653682/.At 48 years old and holder of several American records for marathon times, Salazar's story is eerily reminiscent of Jim Fixx, who died at age 52 after writing a bestselling book, The Complete Book of Running. Thankfully, Salazar's story has a happier ending. Fixx died at a time when prevention of heart disease was quite primitive. Lipoprotein analysis was not broadly available to the public, CT heart scans had not yet been invented. Even statin drugs were just a gleam in the pharmaceutical industry's eye. But not so with Salazar. This Cuban-born marathoner experienced his heart attack at at a time when enormously useful steps can be taken to 1) document the extent of disease with a CT heart scan (the presence of a stent just means that one artery can't be "scored"), and 2) identify the causes of his disease.I suspect that the fact that yet another marathoner in the limelight will once again prompt the (likely non-sensical) conversation about long-distance running and the increased risk of heart disease. Unfortunately, I fear that the real cause will be left unidentfied and untreated: Lipoprotein(a), or Lp(a).It's almost certain that Fixx had Lp(a), given the fact that his dad had a heart attack at age 35. Running simply postponed the untreated inevitable.I hope Mr. Salazar is surrounded by doctors who have his true interests in mind (not just procedural excitement) and ask the crucial question: Why? The answer is almost certain to be Lp(a). << Older posts Newer posts >> Newer posts12...818283848586878889...123124Older posts

Lower numbers, particularly those <100, can grow at seemingly much faster rates if viewed by percent per year increase. If no effort is taken to stop the growth in your coronary plaque, then scores of 10, 20, 30, or the like can easily grow 50-100% per year. In contrast, scores of 1000, 1500, and 2000 tend to grow at "slower" rates of 20% or so per year without corrective efforts, even though the absolute growth may be substantial. (Obviously, this bit of confusion can be best eliminated by reducing your heart scan score, but it doesn't always work out that way.)If we were all adept at advanced math, we should probably rely on logarithmic measures of plaque increase, rather than percent increase. Or, you can just keep in mind that the rate of plaque growth must always be viewed in the context of the absolute score.
Mr. Salazar: Check your Lp(a) 9. July 2007 William Davis (8) Marathon star Alberto Salazar was just released from the hospital following a heart attack and a heart catheterization that led to a stent. The MSNBC version of the report can be viewed at http://www.msnbc.msn.com/id/19653682/.At 48 years old and holder of several American records for marathon times, Salazar's story is eerily reminiscent of Jim Fixx, who died at age 52 after writing a bestselling book, The Complete Book of Running. Thankfully, Salazar's story has a happier ending. Fixx died at a time when prevention of heart disease was quite primitive. Lipoprotein analysis was not broadly available to the public, CT heart scans had not yet been invented. Even statin drugs were just a gleam in the pharmaceutical industry's eye. But not so with Salazar. This Cuban-born marathoner experienced his heart attack at at a time when enormously useful steps can be taken to 1) document the extent of disease with a CT heart scan (the presence of a stent just means that one artery can't be "scored"), and 2) identify the causes of his disease.I suspect that the fact that yet another marathoner in the limelight will once again prompt the (likely non-sensical) conversation about long-distance running and the increased risk of heart disease. Unfortunately, I fear that the real cause will be left unidentfied and untreated: Lipoprotein(a), or Lp(a).It's almost certain that Fixx had Lp(a), given the fact that his dad had a heart attack at age 35. Running simply postponed the untreated inevitable.I hope Mr. Salazar is surrounded by doctors who have his true interests in mind (not just procedural excitement) and ask the crucial question: Why? The answer is almost certain to be Lp(a).
