Be patient with niacin 19. stycznia 2007 William Davis (0) Mel's HDL started at 37 mg/dl one year ago. Mel had several other abnormal lipoprotein patterns along with his HDL (inc. small LDL and Lp(a)), but HDL was clearly a crucial factor in his panel. With a heart scan score of 1166, we needed to raise Mel's HDL to the Track Your Plaque target of 60 mg/dl. So Mel started niacin, our number one method to raise HDL, in addition to reducing his exposure to wheat products and other high glycemic index foods; increasing his physical activity; trying to reduce his excess tummy fat; fish oil; dark chocolate (2 oz per day) and red wine (1-2 glasses per day, preferably dark French reds). The form of niacin we often choose is SloNiacin (Upsher Smith), available over-the-counter for about $12-14 per 100 tablets.Mel started out with niacin 500 mg per day at dinner, increased to 1000 mg at dinner after four weeks. Although this is usually too soon to reassess HDL, Mel insisted. His HDL 41 mg/dl. Mel's disappointment was palpable. He was the usual type A personality: he wanted his HDL higher--now! So Mel insisted that we increase niacin to 1500 mg per day. (We never go higher than this if low HDL or small LDL is the indication for niacin; only when Lp(a) is present do we go higher.)Six months into this process, HDL: 45 mg/dl. Still a sluggish response. One year later, HDL: 68 mg/dl. Finally!That is typical for niacin, as well as combination of lifestyle changes Mel made. None of them result in an immediate rise in HDL; all take months to 1-2 years to exert full HDL-raising effect. Think of HDL as the 82-year old grandma who takes a long time to cross the street-she does get there!Note: Doses of niacin >500 mg per day should be taken with medical supervision.
Can vitamin D be a SOLE risk factor? 18. stycznia 2007 William Davis (6) Here's a crazy question. It occurred to me as I was talking to Drew, a slender, active 54-year old dentist with no bad habits including no smoking. Drew's heart scan score was 222. His lipoprotein analysis mostly revealed a lot of nothing, which is unusual. The only pattern that showed up was a modestly high LDL of 122 mg/dl with a very slight excess of small LDL. That's it. I would not be satisfied that these were sufficient cause for Drew's level of coronary plaque. Drew's 25-OH-vitamin D3 level: 15 ng/ml--severe deficiency--despite the fact that his doctor had suggested that he take a vitamin D2 preparation. In other words, Drew had been profoundly deficient, probably for years.Given the unimpressive cholesterol and lipoprotein values, could vitamin D serve as a trigger for coronary plaque all by itself? I don't have an answer and know of nobody else who does. However, my opinion is that vitamin D is indeed a potent risk that can cause heart disease as a sole risk factor. Perhaps it's another piece of circumstantial evidence suggesting that vitamin D has an enormous influence on health, including coronary plaque. Interestingly, the only other health problem Drew has had is prostate cancer, treated a few years ago with prostate removal and radiation. Good evidence suggests that vitamin D deficiency escalates risk of prostate cancer substantially. By the way, I've seen people taking vitamin D2 preparations, called "ergocalciferol," who are every bit as deficient as those who take no vitamin D at all. Avoid D2 or ergocalciferol preparations: they're worthless.
Does fish oil raise LDL cholesterol? 17. stycznia 2007 William Davis (1) Katie had an LDL (conventionally calculated) of 87 mg/dl, HDL of 48 mg/dl. She added fish oil, 6000 mg per day. Three months later her LDL was 118 mg/dl, HDL 54 mg/dl. In other words, LDL increased by 31 mg. What gives? Several studies have, indeed, shown that fish oil raises LDL cholesterol, usually by 5-10 mg/dl. Occasionally, it may be as much as 20-30. Unfortunately, many physicians often assume that it's the (minor) cholesterol content of fish oil capsules, or some vague, undesirable effect of fish oil. It's nothing of the kind. Since we based Katie's program on (NMR) lipoprotein analysis, not conventional lipids (HDL, calculated LDL, triglycerides, total cholesterol), I knew that Katie also had a severe excess of intermediate-density lipoprotein, or IDL, and very-low density lipoproteins, VLDL. This signifies that after a meal, dietary fats persist for 12, 24,or more hours. Fish oil is a very effective method to clear IDL and VLDL, though sometimes it also causes a shift of some IDL and VLDL into the LDL class. Thus, the apparent increase in LDL. Another contributor: Conventional LDL is a calculated value, not measured. The calculation for LDL is thrown off by any reduction in HDL or rise in triglycerides. In Katie's case, the rise in HDL from 48 to 54 means that calculated LDL is becoming more accurate and rising towards the true measured value. At the start, Katie's true measured LDL was 122 mg/dl, 35 mg higher than the calculated value. Calculated LDL is therefore approximating measured LDL more accurately as HDL rises. The most important lesson to learn is that, if LDL rises significantly on fish oil and you haven't had lipoproteins formally measured, there may have been a substantial postprandial abnormality like IDL that was unrecognized.
Heart disease is everywhere 16. stycznia 2007 William Davis (0) If you ever need convincing that heart disease is everywhere, you should do what I do: subscribe to Google Alerts and have them forward news anytime the search phrase "heart attack" crosses the web. (Just go to Google, click on "more" to the right of the search bar, and follow the links.)Some recent samples:Workmates resuscitate driver after heart attack A woman coal mine truck driver had a heart attack and required resuscitation with a defibrillator 3 times on the way to the hospital. Heart attack kills groom at receptionA 34-year old man died during his wedding reception, leaving behind his 26-year old new wife.Heart attack ruled as cause of crash An Alabama man drove his pick-up truck into oncoming traffic while suffering a heart attack. Heart-attack victim to return to Hamburg stage Country music artist, Michael Harding, suffered a heart attack and cardiac arrest during a performance. He is apparently recovered and returning to the stage. That's just a sample from the last two days. While you and I are carry on a conversation on reversal of heart disease, our neighbors and friends drop over every day. Even though I witness successful heart disease reversal routinely, the rest of the world is not participating. Pass it on: Coronary disease is identifiable, preventable, controllable, and reversible.
Watch your weight plummet:Be a super vegetarian 14. stycznia 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. stycznia 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. stycznia 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. stycznia 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. stycznia 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.

Heart scan curiosities #5 8. stycznia 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.
