A new Track Your Plaque record: 63% reduction 14. يوليو 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. يوليو 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. يوليو 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. يوليو 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).
Heart Scan Curiosities #8: Fat heart 8. يوليو 2007 William Davis (2) Here's a curious incidental finding on a heart scan: an unusual fat accumulation around the heart. The arrows point to an unusually large accumulation of fat tissue on either side of the heart. This man was mildly but not excessively overweight at 5 ft 10 inches and 201 lbs. I know of no specific implications of this curiosity. It makes me wonder if he was very obese at one time and has since lost the weight.
Chocolate and blood pressure 7. يوليو 2007 William Davis (1) A recent very detailed and clean study on the effects of a small serving of dark chocolate on blood pressure was just published in the Journal of the American Medical Association. I was going to do a little Blogging on this interesting study but I read the Fanatic Cook's wonderfully insightful comments. I'd direct you to her discussion, instead: A small daily dose of dark chocalate lowers blood pressure at http://fanaticcook.blogspot.com/. I couldn't have said it any better. By the way, the authors of the study had no financial ties to the chocolate or cocoa industry. Refreshing.
Does prevention save money? 7. يوليو 2007 William Davis (2) Prevention and reversal of heart disease are undoubtedly preferable to the current crash and repair model currently followed by doctors and hospital, the model that has created an enormous medical device industry to support it. But does it save money? This debate often boils down to a metric of "lives saved per $100,000". Thus, the statin drugs (of course) have been subjected to such analyses and have been shown to be "cost-effective." But how does a powerful heart disease prevention and reversal program like Track Your Plaque compare to the current crash and repair procedural approach to heart disease? This is a very difficult analysis, one that is subject to enormous variation, depending on the population studied and the prevalence of disease, the local practice habits (e.g., in the northwest Cleveland suburb of Lorain, virtually everybody going to the hospital for any heart problem gets one or several heart catheterizations), and other factors. There's also the difficulty of what should constitute a prevention program. Is it like that used in the COURAGE Trial of "optimal medical therapy" that included nitroglycerin, aspirin, a beta blocker, and statin drug (which we regard as a laughably silly approach), or one like Track Your Plaque in which we try to correct the causes of heart disease, not just palliate (BandAid) them? Costs vary. The "optimal medical therapy" is very costly due to its reliance on medications to treat symptoms. Our program is somewhat costly because of the reliance on a CT heart scan and lipoprotein analysis (though, in the long perspective, our costs are modest). We asked this question and came up with a lengthy analysis. Bottom line: Following the Track Your Plaque program saves enormous sums of money. Because of the complexity of the analysis, which is theoretical and not a real-world test, we confined our analysis to men in the 40-59 year old age group. If this group alone were to subscribe to a intensive but rational program of prevention like Track Your Plaque, over $20 billion dollars per year would be saved. If the analysis were extended to women of all ages and men older than 59, the numbers would balloon to many more tens of billions of dollars. Such a savings wouldn't cure the healthcare system's growing financial crisis, but it sure would be a big help. Sort of like converting to a hydrid car--you don't eliminate the need for gas, but you'll save a lot in fuel costs. The Track Your Plaque approach makes sense because it is, bar none, the most powerful approach to gaining hold of heart disease risk available. But it also makes sense from a financial standpoint. Now, if we can only convince the hospitals, the $30 million annual salary device manufacturer CEO, and my procedure-crazy colleagues that this way makes more sense. Watch for our analysis on an upcoming Track Your Plaque Special Report.
Where should fiber come from? 7. يوليو 2007 William Davis (1) Ray had the usual protuberant belly overhanging his beltline of someone who was over-reliant on processed starches, particularly wheat. After all, he ran a sandwich bakery. He sheepishly admitted that he ate the products of his own production line every day while at work, even bringing a few sandwiches home.At 5 ft 10 inches, 201 lbs, he wasn't terribly overweight, but all the excess was in his beltline. He had the lipoproteins to match: HDL 38 mg/dl, triglycerides 180 mg/dl, 83% of all LDL particles were small, excess VLDL and IDL. Blood pressure: 140/88. Blood sugar: 112 mg/dl. With a CT heart scan score of 698, Ray had some work to do. Among the strategies we discussed was a need to dramatically reduce, perhaps eliminate, wheat products and other high-glycemic index foods. "You've got to be kidding me!" Besides the inconsistency with his business, he was puzzled on what foods were edible for his pattern. We discussed how he could easily replace his reliance on wheat and breads with more vegetables, more fruits, more lean proteins, and more healthy oils. "But I won't get any fiber!" he declared. That was why he tried to choose whole wheat bread for his sandwiches. This is a common concern when we discuss how grains, particuarly wheat, need to be sharply reduced. In the most recent edition of his Paleo Diet Newsletter, Dr. Loren Cordain has laid out a wonderful graph that beautifully illustrates the issue: (From The Paleo Diet Newsletter at http://www.thepaleodiet.com/newsletter/back_issues.shtml)In other words, reducing or eliminating "fiber-rich" grains and replacing their calories dramatically increases fiber content of your diet.For Ray, whose livelihood depends on promoting and perpetuating the use of wheat breads, it will be tough to keep him on the right track. My prediction: the results he will see will be substantial and it will become difficult to return to eating his own products. There's no doubt that this concept can be economically disruptive for many people, including Ray. It's a tough situation we've created: a huge industrial complex based on growing grains and wheat, processing it into breakfast cereals, bagels, pretzels, crackers, and sandwiches. But it has also contributed to the epidemic of obesity and the patterns that people like Ray have. But the startling fact remains: If replaced with vegetables and fruits, reducing grains increases the fiber content of your diet, and not jsut a little bit, but enormously. If green peppers and spinach had brand names like "Fiber One" and "Smart Start" along with flashy boxes, then maybe it would be an easier concept to grasp.

The Detection Gap 5. يوليو 2007 William Davis (3) You've heard of the Generation Gap, the Income Gap, the Technology Gap, the Gender Gap, and the Achievement Gap.How about the Detection Gap? Haven't heard of it? That's the gap between coronary heart disease detected by conventional methods widely practiced in the community and the real prevalence of the disease.The standard approach to coronary heart disease detection is a relatively simple formula. One of three things are sought:1) Symptoms of heart disease like chest pain or breathlessness. 2) An abnormal EKG or abnormal stress test.3) A catastrophe like heart attack or sudden cardiac death. By this equation, the American Heart Association (AHA) estimates that 36% of American men and women have coronary disease. However, we say the number is more like 48%. That's the number we arrive at when we ask: How many men and women have CT heart scan scores above zero?The difference is the Detection Gap. Though only around 12%, it amounts to millions of people. The problem is that, by the conventional approach to detection of heart disease, you often don't know you have it until you're lying on a hospital gurney being wheeled off to a major procedure. Or your friends, family or neighbors find your body.If heart disease is detected by a CT heart scan, it tends to be early, before catastrophe strikes. You can use tools like niacin, vitamin D, flaxseed, etc., all the components of the Track Your Plaque approach. If heart disease is detected by waiting for the appearance of symptoms, then a stress test (usually nuclear) is followed by a heart catheterization, stents, bypass, etc. So there's more than a Detection Gap. There's also a difference in the sorts of therapies chosen. There's certainly a difference in cost. In my view, there is no rational reason not to close the Detection Gap. While CT heart scan scores aren't perfect, they're damn close. The Detection Gap could be closed to around 2%. We'd also save billions of dollars.
Apoprotein B on VAP 3. يوليو 2007 William Davis (3) We've just received an announcement that, if your Vertical Auto Profile lipoprotein test (Atherotech) is provided through the national Quest laboratories (a large national laboratory company), they will include an apoprotein B. This represents an improvement over the previous "direct LDL," a measured LDL cholesterol. Recall that standard lipid panels obtained in hospitals and doctors' offices is a calculated LDL, based on the 40-some year old Friedewald calculation. In my view, the Friedewald calculated LDL is a dinosaur that is virtually useless and needs to be retired. Direct, or measured, LDL is a slight improvement. It removes some of the inaccuracy introduced by the assumptions built into the calculated value. Apoprotein B (also called apoprotein B100) is yet another improvement. Apo B's have been available for years, but was not provided on the VAP. The Atherotech people have done a good job of making VAP more broadly available through "drawing stations" and proponents like Life Extension. Adding an ApoB is a favorable development, since it incorporates the risk of other ApoB-containing particles, like VLDL, IDL, and Lp(a). Several studies like the Quebec Cardiovascular Study have shown that ApoB is a superior predictor of heart disease compared to calculated LDL. I still believe that the gold standard for assessing risk from an LDL standpoint is the LDL particle number along with the other measures provided by the NMR assay (Liposcience). However, the addition of the ApoB to VAP adds greater confidence to the measures provided by this technique. Those of you who rely on the VAP assay provided by Quest for your Track Your Plaque program for control of CT heart scan scores therefore have access to this improved panel.
