Do stents prevent reversal? 27. January 2007 William Davis (3) I've seen this phenomenon several times now: A highly-motivated Track Your Plaque participant with a stent in one artery will do all the right things--lose weight, achieve 60:60:60 in basic lipids, identify and correct hidden lipoprotein disorders, take fish oil, correct vitamin D, etc.Follow-up heart scan shows dramatic reduction in scoring in the two arteries without stents--30% per artery. But the artery with the stent will show marked increase in scoring above and/or below the stent. (It's impossible to tell what happens in or around the stent itself from a calcium scoring standpoint, since steel looks just like calcium on a CT heart scan.) In other words, there is marked plaque growth in the vicinity of the stent, despite the fact that dramatic reversal of atherosclerosis has occurred in other arteries without stents. Should we take this to mean that a stent destroys the opportunity for atherosclerotic plaque reversal in the stented artery? I don't know, but I fear this may be true. What dangers does this different sort of plaque pose? Is it the result of the injury imposed at time of stent implantation, some modification of flow or biologic responses as a result of the presence of the stent? These are all unanswered questions. But I believe that it is yet another suggestive piece of evidence that the best stent is no stent at all.
At what score should I have a heart cath? 25. January 2007 William Davis (0) This question comes up frequently: At what specific heart scan score should a heart catheterization be performed? In other words, is there a specific cut-off that automatically triggers a need for catheterization? In my view, there is no such score. We can't say, for instance, that everybody with a score above 1000 should have a catheterization. It is true that the higher your score, the greater the likelihood of a plaque blocking flow. A score of 1000 carries an approximately 25-30% likelihood of reduced blood flow sufficient to consider a stent or bypass. This can nearly always be settled with a stress test. Recall that, despite their pitfalls for uncovering hidden heart disease in the first place, stress tests are useful as gauges of coronary blood flow. But even a score of 1000 carries a 70-75% likelihood that a procedure will not be necesary. This is too high to justify doing heart catheterizations willy-nilly. Unfortunately, some my colleagues will say that any heart scan score justifies a heart cath. I believe this is absolutely, unquestionably, and inexcusably wrong. More often than not, this attitude is borne out of ignorance, laziness, or a desire for profit. Does every lump or bump justify surgery, radiation, and chemotherapy on the chance it could represent cancer? Of course not. There is indeed a time and place for these things, but judgment is involved. In my view, no heart scan score should autmatically prompt a major heart procedure like heart catheterization in a person without symptoms.
Niacin makes NY Times 24. January 2007 William Davis (0) In the wake of the crash and burn of Pfizer's torcetrapib, media attention has turned up the miracles of . . .good old niacin. The NY Times carried a well-written report on niacin in its recent report, An Old Cholesterol Remedy Is New Again. (Read the entire report at http://www.nytimes.com/2007/01/23/health/23consume.html?em&ex=1169701200&en=670fa84ae2ea648c&ei=5087%0A)Among their comments:...torcetrapib worked primarily by increasing HDL, or good cholesterol. Among other functions, HDL carries dangerous forms of cholesterol from artery walls to the liver for excretion. The process, called reverse cholesterol transport, is thought to be crucial to preventing clogged arteries.Many scientists still believe that a statin combined with a drug that raises HDL would mark a significant advance in the treatment of heart disease. But for patients now at high risk of heart attack or stroke, the news is better than it sounds. An effective HDL booster already exists.It is niacin, the ordinary B vitamin.In its therapeutic form, nicotinic acid, niacin can increase HDL as much as 35 percent when taken in high doses, usually about 2,000 milligrams per day. It also lowers LDL, though not as sharply as statins do, and it has been shown to reduce serum levels of artery-clogging triglycerides as much as 50 percent. Its principal side effect is an irritating flush caused by the vitamin’s dilation of blood vessels.Despite its effectiveness, niacin has been the ugly duckling of heart medications, an old remedy that few scientists cared to examine. But that seems likely to change.“There’s a great unfilled need for something that raises HDL,” said Dr. Steven E. Nissen, a cardiologist at the Cleveland Clinic and president of the American College of Cardiology. “Right now, in the wake of the failure of torcetrapib, niacin is really it. Nothing else available is that effective.”In 1975, long before statins, a landmark study of 8,341 men who had suffered heart attacks found that niacin was the only treatment among five tested that prevented second heart attacks. Compared with men on placebos, those on niacin had a 26 percent reduction in heart attacks and a 27 percent reduction in strokes. Fifteen years later, the mortality rate among the men on niacin was 11 percent lower than among those who had received placebos.'Here you have a drug that was about as effective as the early statins, and it just never caught on,' said Dr. B. Greg Brown, professor of medicine at the University of Washington in Seattle. 'It’s a mystery to me. But if you’re a drug company, I guess you can’t make money on a vitamin.'Of course, you and I don't have to wait for the media to endorse something. I'm nonetheless thrilled that this hugely helpful vitamin is gaining greater recognition. My preferred form nowadays is over-the-counter SloNiacin (Upsher Smith). Weve seen no liver side-effects and a minimal quantity of flushing. It's also reasonably priced, $13.99 for 100 tablets of 500 mg at Walgreen's. That's a lot cheaper than prescription Niaspan at $130 for 60 tablets. Perhaps the notoriety will cut back on the silly responses from some physicians that I still hear about from patients: "My doctor said to stop the niacin because it's going to destroy my liver."
Wheat: the nicotine of food 24. January 2007 William Davis (1) Yes, we know that wheat contributes to creating small LDL, drops HDL, raises triglycerides, and VLDL. We also know it indirectly slows the clearance of after-eating fats from the blood (curious, I know). Wheat products also increase inflammation (C-reactive protein), raise blood sugar, and contribute tremendously to diabetes. What many people don't know is that wheat products also have an addictive quality: have one donut and you want another. It's true for bread, breakfast cereals, pretzels, cookies, etc. How many times have you had just one Oreo cookie? Curiously, elimination of wheat products, unlike elimination of nicotine, usually causes the cravings to disappear. In other words, if you stop smoking cigarettes, the desire to smoke doesn't go away. With wheat products, the often overwhelming desire for more wheat products often just goes away. But most people are simply unable to dramatically reduce or eliminate wheat products from their daily diet and therefore struggle each and every day with excessive cravings for bagels, donuts, cookies, breads, etc. Try this useful experiment: Eliminate wheat products for a month and see what happens. Most people drop blood pressure, lose the tummy excess, feel more alert, see a drop in blood sugar, experience improvements in lipoproteins, and regain control over appetite.
Good time for a heart attack? 22. January 2007 William Davis (0) Man Has Heart Attack At Right Place, Right Time If Robert Ricard had picked the wrong restaurant for lunch, he might have died.The 71-year-old Michigan man suffered a heart attack shortly after ordering a glass of wine with friends at Bentley's Roadhouse on Saturday.Luckily, a disaster medical team was sitting nearby.A TV station in Michigan reported the above story. You've heard these "if it wasn't for ___, so and so would have died" stories. They're reported in all cities at one time or another. What amazes me about these common local stories is that they're accepted at all. The question that comes to my mind is "Why couldn't the heart attack have been averted in the first place?" Early identification then, as close as humanly possible, elimination of risk would have been a preferable path. Of course, it may not be the role of the media to cast judgement on why and how the entire episode could have been completely prevented from occurring. But you shouldn't fall into the same trap of complacency. We cannot expect others to save us when the "big one" hits. Your best assurance is to never have one in the first place.
How good is the South Beach Diet? 21. January 2007 William Davis (2) I'm a fan of the South Beach Diet. Though it is billed as a program for weight loss (for which it is very effective), it is really a program for health. The basic approach of South Beach involves:Eat good fats — Choose good fats from olive oil, canola oil, peanut oil, flaxseed oil, walnut oil, avocados, nuts, and fish. Omega-3 (fish oil) supplements are also fine. Eat good carbs — Good carbs include high-fiber, nutrient-dense fruits, vegetables, legumes, and whole grains. Eat lean protein — Good sources include eggs, low-fat dairy, nuts, seeds, legumes, skinless white-meat poultry, fish, shellfish, lean cuts of meat, and vegetarian options such as tofu. (From The South Beach Diet, Dr. Arthur Agatston) There's no doubt that South Beach can yield dramatic weight loss. In my experience, the success in weight loss depends on 1) how unhealthy your diet was in the first place, and 2) how long you can stick to Phase I, the inital phase during which weight loss is most dramatic. Some people have to periodically cycle back to Phase I to break a "plateau" or to lose faster. But South Beach is also healthy. It has all the ingredients of a healthy eating program: Low saturated and hydrogenated fats, rich in monounsaturated fats, high fiber, low- to moderate- glycemic index, vegetables and fruits, lean proteins. The Atkins' diet, in contrast, while very effective for weiglht loss, is an unhealthy process. I've seen lots of bladder infections, constipation, skin rashes, and kidney stones. That's just in the short term. If you stick to the "induction phase" (the no carbohydrate, low fiber, indiscriminate fat initial phase) for an extended period, I suspect that other adverse internal phenemena also develop that might not show for years, like cancer. But--it does work for weight loss!South Beach's Phase I is also carbohydrate restricted, but steers you towards healthier foods, such as healthy oils from olive and canola, raw or dry roasted nuts, and lean proteins and vegetables. What really makes South Beach special, however, are its clever recipes. Dr. Arthur Agatston (the author) involved chefs from the restaurants in the South Beach area of Miami to help create healthy yet delicious recipes. We've tried many of them and, while they are different from traditional fare, are delicious and satisfying for the most part.Criticisms? None, really. But, when my patients choose South Beach (which I often encourage), I often have to impress on them that the Track Your Plaque program is not about weight loss. It is about seizing control of a potentially life-threatening disease. It is a far more important goal with greater implications. Weight loss is just one aspect of a coronary plaque control effort. For this reason, we sometimes have to make changes in the South Beach program to allow for correction of specific lipoprotein patterns. The most common modification is in people with small LDL particles. This pattern often does indeed respond to weight loss and/or niacin. However, it occasionally persists despite these efforts. We then will ask the patient to continue to restrict the re-introduction of wheat products, though it is allowed after Phase I in South Beach. In other words, for this specific and sometimes difficult to control lipoprotein pattern, a spedific modification of the off-the-shelf South Beach program is sometimes necessary. Of course, the diet is created to suit everybody. Lipoprotein analysis permits detailed insight into your patterns and it's only to be expected that specific modifications might be needed. But, as written, you can do quite well in your plaque control program by sticking to South Beach.
Be patient with niacin 19. January 2007 William Davis Toggle navigation Home Blog Home Archive Join Now Log in Watch your weight plummet:Be a super vegetarian 14. January 2007 William Davis (0) Here's a neat trick for losing weight: Become a strict vegetarian for 3 days. Before you yawn or say "Yecchhhh!", let me elaborate.Pick some time period. It doesn't have to be 3 days. It could be 2 days, or 5 days, or two weeks. But, for the period you choose, eat only vegetables. No meat, cereals, breads, milk, cookies, etc. Vegetables alone could get monotonous, so make them interesting. Possibilities include:--Hummus--add a little bit of olive-oil, chopped garlic, paprika, red pepper.--Tabouleh--I get mine from Trader Joe's and it's delicious.--Salsa--Low in calories, rich in lycopene and other flavonoids, with no nutritional downside. Also, pico de gallo--chopped tomatoes, onions, jalapeno chiles, cilantro, cucumbers. --Mustards--hot, yellow, brown, spicy, gourmet, horseradish, etc.--Cocktail sauce--i.e., ketchup and horseradish. Use the low-carb ketchup made without high fructose corn syrup. --Tapenades--e.g., olive tapenade made with chopped olives, capers, and olive oil.--Pesto-made with basil, garlic, and olive oil.--Spices and herbs--basil, arugula, peppers, mustard powder, garlic, cilantro, ginger, etc. --Vinegars--wine, Balsamic, rice, apple cider.--Infused olive oils--infused with garlic is especially delicious,e.g., added to hummus.--Bean dips--white bean dip, roasted bean dip, etc.With the varieties of ways to jazz up your vegetables, you couldn't possibly be bored.For example, for breakfast on day 1, eat sliced cucumbers and green peppers dipped in garlic-infused olive oil hummus and a handful of almonds. For a snack, some walnuts, sunflower seeds, sliced zucchini dipped in salsa. For lunch, a salad with an olive oil and balsamic vinegar dressing. For dinner, tablouleh, a cucumber and tomato salad, celery sticks dipped in pico de gallo. All vegetables can be eaten without restricting portion size, since calorie content of vegetables are so low compared to other calorie-dense foods. (See The Heart Scan Blog from a few days back, "One bit or many mouthfuls?" at http://heartscanblog.blogspot.com/2007/01/one-bite-or-many-mouthfuls.html.) This approach works nearly as well as fasting. A half-pound per day weight loss or more is common and painless. You'll also feel great living on low glycemic index foods. (Photos courtesy Wikipedia.) Dr. Agatston to the rescue 12. January 2007 William Davis (0) Dr. Arthur Agatston, author of wildly successful South Beach Diet, has just released a new book titled The South Beach Heart Program. Dr. Agatston has started on a media speaking circuit to promote his book and concepts. A reporter from Time, who interviewed Dr. Agatston, commented:". . .not enough doctors prescribe niacin for their heart patients, even though the medicine is a proven treatment for raising 'good' cholesterol. Physicians are reluctant, Agatston suggests, because niacin requires diligent follow-up to watch for side effects, taking time that most primary-care practices cannot afford. On the other hand, he says, too many doctors are performing heart operations that represent a financial windfall for hospitals. Bottom line: there isn't as much money to be made in prevention as in treatment."Amen. Dr. Agatston echoes many of the concepts that the Track Your Plaque program advocates. His notoriety is going to help disseminate the idea that 1) CT heart scans are the #1 method to identify hidden atherosclerotic coronary plaque, 2) taking control of your heart scan score is the best way to seize hold of your future, and 3) the present-day popularity of heart procedures like stents and bypass is intolerable, inexcusable, and needs to be reined back.Agatston also brings great credibility and fairness to the conversation and his comments will gain tremendous attention in the press and with the public. When is a vitamin not a vitamin? 12. January 2007 William Davis (0) When it's a hormone. That's the stand that several researchers in vitamin D have taken and I think they're right. Dr. John Cannell has made a fuss over this in his www.vitamindcouncil.com website. Structurally, vitamin D is most closely related to testosterone, estrogen, and cortisol. You wouldn't call testosterone vitamin T, would you? Vitamins are also meant to be obtained from food. Yes, vitamin D is in milk but only because humans are required to put it there to prevent childhood rickets. Otherwise, the only substantial food source of vitamin D is in oily fish like salmon and then only a modest quantity. Vitamin D is cholecalciferol, a hormone. Deficiencies of hormones can have catastrophic consequences. Imagine that every winter your thyroid gland shuts down and produced no thyroid hormone. You'd get very ill, gain 30 lbs, lose your hair, feel awful. That's what happens when you're sun deprived and thereby deficient in cholecalciferol--you're deficient in a hormone. And it happens to most of us every year for many months. I continue to witness spectacular effects by bringing 25-OH-vitamin D3 blood levels to 50 ng/ml with supplementation, including an apparent surge in success dropping heart scan scores. An epidemic of heart disease reversal 10. January 2007 William Davis (3) Heart disease reversal is nothing new in my office. However, I have to admit that it's not something that generally happens each and every day. As our approach is refined, we are witnessing an unprecedented frequency of plaque reversal. Since Monday (today is Tuesday), I've seen four people who have regressed their coronary plaque and dropped their heart scan score. Pat was the most recent addition to this list. At age 53, I was honestly surprised at the ease of dropping her heart scan score from 128 to 42 in the space of a year. I was surprised because among her lipoprotein patterns was the dreaded combination of lipoprotein(a) and small LDL, probably the most aggressive risk for heart disease I know of and also among the most difficult to gain control over. She also suffered a deep personal tragedy in her family, an emotional convulsion that can sometimes wipe out any hope of plaque reversal. I'm hopeful that this virtual epidemic of heart disease reversal continues. And I hope that you participate in it. Second heart scan and heart attack risk 9. January 2007 William Davis (0) At first, Joe felt disappointed, defeated, and frightened. After his heart scan, a radiologist at the center told him that his score of 264 was moderately high. He told Joe that he was at moderate risk for heart attack and that a nuclear stress test was going to be required. This left Joe feeling confused. After all he'd had a heart scan 18 months earlier and his score was 278, 5% higher. I reassured Joe that the radiologist had not been aware that Joe had a prior heart scan. The radiologist didn't know that Joe's heart scan score had actually been reduced. In fact, Joe's risk for heart attack was not moderate--it is now very low, since his score was 5% lower. While growing plaque is active plaque, shrinking plaque is inactive plaque and thereby at far less risk for heart attack.I wrote about this phemonenon in a previous Blog: When is a heart scan score of 400 better than 200? at http://heartscanblog.blogspot.com/2006_09_01_archive.html. When you've had more than one scan, the risk for heart attack suggested by the score takes a back seat to the rate of change of your score. In other words, even though Joe's score of 264 represented a moderate risk (of approximately 3% per year, roughly 30% over 10 years), this no longer held true, since it actually represented a 5% decrease over a previous score. Joe's risk for heart attack is probably close to zero. ALWAYS view your second (or any subsequent) heart scan score in the context of your previous score, not in isolation.

January 2007 William Davis (1) Despite the controversy over drug-coated stents, I maintain that the best stent is no stent at all. Yes, there are indeed times when such things are necessary, but not with the frequency that they are implanted nowadays. Another reason why stents are an undesirable phenemenon is that they muck up your heart scan. Take a look:The long white object in the center is a stent in the left anterior descending artery of this 60 year old man. Just beyond the stent (at about 1 o'clock from the stent) is a plaque that could be scored. However, you can see that, with the presence of the stent, the bulk of this artery is no longer "scorable". If this man wishes to "track his plaque", he will have to be content with tracking only the circumflex and right coronary arteries, the other two arteries without stents. The stainless steel or similar metallic materials of current stents simply prevent us from seeing through them for plaque scoring purposes. It's best if you can simply avoid getting one for this and other reasons.Track Your Plaque Members: Watch for the upcoming editorial by our Heart Hawk on drug-eluting stents.
