The Framingham Crap Shoot 22. November 2008 William Davis (2) The Framingham risk score is a risk-assessment tool that has become the basis for heart disease prediction used by practicing physicians. The Framingham system determines that:· 35% of the adult population in the U.S., or 70 million, is deemed “low-risk.” Low-risk is defined as the absence of standard risk factors for heart disease; low-risk persons have no more than a 1-in-20 chance (5%) of dying from heart disease in the next 10 years. Physicians are advised by the American Heart Association (AHA) and its experts that no specific effort at risk reduction is necessary. · 25%, or approximately 50 million, U.S. adults are deemed “high-risk,” based on the presence of 2 or more risk factors. High-risk persons experience a 20%-30% likelihood of heart attack in the next 10 years. People at high-risk are candidates for preventive efforts according to the guidelines set by the Adult Treatment Panel-III (Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults; ATP-III) for cholesterol-reducing statin drug treatment and for “lifestyle-modifying” advice. · The remaining 40% of the adult population, or 80 million people, are judged “intermediate-risk,” with the likelihood of heart attack between 5-20% over the next 10 years. This group should receive preventive advice and might be considered for statin drug treatment. Let’s do some arithmetic. By the above scheme, the low-risk population will experience 3,500,000 heart attacks over the next decade, or 350,000 heart attacks per year. The intermediate-risk population (without preventive treatment) will experience 8,000,000 heart attacks over the 10-year time period, or 800,000 per year. The high-risk population, the group most likely to receive standard advice on diet, exercise, and be prescribed statin cholesterol drugs, will have their risk reduced by 35% by preventive efforts over the 10-year period. This means that heart attacks over 10 years will be reduced from 12,500,000 to 8,125,000 by standard prevention efforts, or reduced to 812,500 heart attacks per year. These numbers are no secret. They are well known facts that have simply come to be accepted by the medical community. In other words, the standard approach to heart attack prediction makes the fact that two million people will succumb to cardiovascular events in the next year no mystery. This exercise in prediction is coldly accurate when applied to a large population.The problem is that this approach cannot reliably distinguish which individuals will have a heart attack from those who will not. From 100 people chosen at random, for instance, the numbers game played above will not confidently identify who among those 100 will have a heart attack, who will not, who will develop anginal chest pains and end up with stents or bypass surgery, or who will die. We just know that some of them will. Some people at high risk will have a heart attack, some people at intermediate risk will have a heart attack, some people at low risk will have a heart attack. For any specific individual (like you or me), it’s a crap shoot.That's why precise individual measurement of cardiovascular risk is required for real risk assessment, not applying broad statistical observations and forcing them to conform to the unique life of a specific individual, particularly risk calculators with as few risk parameters as the Framingham risk score.
At what score should a heart catheterization be performed? 21. November 2008 William Davis (2) That's easy: NONE. (Although I've addressed this previously, the question has come up again many times and I thought it'd be worth repeating.)In other words, no heart scan score--100, 500, 1000, 5000--should lead automatically to procedures in someone who underwent a heart scan but has no symptoms. This question is a common point of confusion. 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 necessary. This is too high to justify doing heart catheterizations willy-nilly. Unfortunately, some of 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 automatically prompt a major heart procedure like heart catheterization in a person without symptoms. If a stress test is normal, signifying normal coronary flow (and there are no other abnormal phenomena, such as abnormal left ventricular function), then there is no defensible rationale for heart procedures. Heart procedures like stents and bypass cannot prevent heart attacks in future; they can only restore flow when flow is poor, or stop the heart attack that is about to occur. However, EVERY heart scan score above zero is a reason to engage in a program of prevention.
"It's genetic" 17. November 2008 William Davis (17) At 53, Sam had been through the wringer with heart disease. After his first heart attack at age 50, he'd undergone four heart catheterizations, 5 stents, and, most recently, a bypass operation. He came to us to see if there was a better solution. After hearing Sam's story, I asked,"Did your doctors suggest to you why you had heart disease?" "Well, they said it was genetic, since my father went through the same thing in his early 50s, though he died after his second heart attack at age 54. They said it was bad luck and nothing could be done about it."Though Sam's case is more dramatic than most, I hear this argument every day: Risk for heart disease is genetic. It's true: There are indeed multiple reasons for inheriting causes for coronary heart disease, genes that heighten inflammatory responses, oxidative responses, modify lipoprotein particles, increase blood pressure, etc. There has even been some excitement over developing chromosomal markers for heightened risk. That's all well and fine, but what can we do about it today?In practical life, many inherited genetic patterns can be expressed in ways that you and I can identify--and correct. They are not chromosomal markers, but end products of genetic patterns. (Although there are indeed identifiable chromosomal markers, they have not yet led to meaningful treatments to my knowledge.) These readily identifiable patterns include:--Lipoprotein(a)--Clearly genetically transmitted, passed from mother or father to each child with a 50% likelihood, then you onto your children if you have it. --Small LDL--Although small LDL is amplified by high-carbohydrate diets and obesity, it can also occur in slender people who do not indulge in carbohydrates --i.e., a genetic tendency. Or, it can be a combination of poor lifestyle magnifying the genetic tendency for small LDL.--Low HDL--Particularly the extremes of low HDL below 30 mg/dl. (Although, interestingly, I am seeing more of these people, though not all, respond to vitamin D replacement. Perhaps an important subgroup of low HDL people are really Vitamin D Receptor (VDR) variants.)--ApoE--Two variants are relevant: ApoE2 and ApoE4. In my experience, it's the E2 that carries far greater significance, though the data are somewhat scanty. ApoE4 people are more sensitive to the fats in their diet (greater rises in LDL with fats; thus, some people advocate a tighter saturated fat restriction with this pattern, though I am not convinced that is the best solution), while ApoE2 people are exceptionally sensitive to carbohydrates, develop extravagant increases in triglycerides, and are very diabetes-prone with even the most minimal weight gain. If two "doses" of the E2 gene are present (homozygotic), then the tendencies are very exagerrated. E4 people are also subject to greater likelihood of Alzheimer's, though it is not a certain risk in a specific individual. --Postprandial disorders--We use the fasting intermediate-density lipoprotein (IDL) as an easy, obtainable index of the ability to clear after-eating byproducts of meals from the blood. Increased IDL has been related to increased coronary, carotid, and aortic aneurysmal disease. --Hypertriglyceridemia-i.e., increases in triglycerides, While not all forms of high triglycerides confer risk for atherosclerosis, many do, particularly if associated with IDL, small LDL, increased LDL particle number and/or apoB. There are more, but you get the point. There are clear-cut genetically-transmitted reasons for greater risk for cardiovascular disease. Some, like lipoprotein(a), yield very high risk. Others, like increased triglycerides, yield mixed levels of risk. Importantly, all of these patterns--ALL--are identifiable and are treatable. Treatment may not always be the easiest thing, but they are treatable nonetheless. While lipoprotein(a), for instance, is the most difficult pattern to correct in the above list, I remind everyone that our current "record holder" for reversal of plaque and heart scan scores--63% reduction--has lipoprotein(a) that we corrected. If you've been told that your risk for cardiovascular disease or coronary plaque is "genetic" and thereby uncorrectable and hopeless, run the other direction as fast as you can. Get another opinion from someone willing to take the modest effort to tell you precisely why.
Tim Russert Revisited 16. November 2008 William Davis (7) A Heart Scan Blog reader brought this piece by Dr. MacDougall to my attention. Dr. MacDougall created a fictitious posthumous conversation between himself and the late Tim Russert. MacDougall paints a picture of a hardworking, hard-living man who adhered to an overindulgent lifestyle of excessive eating. He concludes that a vegetarian, low-fat diet would have saved his life. Beyond being disrespectful, I would differ with Dr. MacDougall’s assessment. In fact, I’ve heard an interview with Mr. Russert’s primary care physician in which the doctor claimed that Mr. Russert had been counseled on the need for a low-fat diet and, in fact, adhered to it quite seriously. Far from being an overindulgent, overeating gourmand, he followed the dictates of conventional dietary wisdom according to the American Heart Association. The low-fat diet articulated by Dr. MacDougall is simply a little more strict than that followed by Mr. Russert.What exactly could Mr. Russert have done to prolong his life? Several basic strategies:--Added fish oil. This simple strategy alone would have reduced the likelihood of dying suddenly by almost half. --Eliminated wheat and cornstarch—Mr. Russert developed diabetes in the last few years of his life. By definition, diabetes is an inability to handle sugars and sugar-equivalents. Wheat and cornstarch yield immediate and substantial surges in blood sugar greater than table sugar; elimination causes weight to plummet, blood sugar to drop, and diabetes (at least in its early phases) can be eliminated in many people, particularly those beginning with substantial excess weight.Just those two strategies alone would more than likely have avoided the tragic death that brought Mr. Russert’s wonderful life and career to an abrupt end. Of course, he could have even taken his heart health program even further, as we do in the Track Your Plaque program. While the conversation has focused on how to avoid tragic events like sudden cardiac death, why not take it a step farther and ask, "How can coronary plaque be measured, tracked, and reversed?"In that vein, Mr. Rusert could have restored vitamin D to normal levels; identified all hidden sources of heart disease using lipoprotein testing (though he had small LDL without a doubt, given his generous waist size, HDL of 36 mg/dl and high triglycerides); considered niacin. Simple, yet literally lifesaving efforts, that make reversal much more likely. Those simple steps, in fact, would have tipped the scales heavily in Mr. Russert’s favor, making a heart attack and/or sudden death from heart disease exceptionally unlikely.
Water: Bottled vs. tap 16. November 2008 William Davis (4) The Fanatic Cook has a great post discussing the findings of the Environmental Working Group (EWG) on the quality of bottled water. The full text of the study from the EWG can be viewed here. They report that "the bottled water industry promotes an image of purity, but comprehensive testing by the Environmental Working Group (EWG) reveals a surprising array of chemical contaminants in every bottled water brand analyzed" . . . After analyzing 10 brands, they conclude that "tests strongly indicate that the purity of bottled water cannot be trusted. Given the industry's refusal to make available data to support their claims of superiority, consumer confidence in the purity of bottled water is simply not justified.""EWG's study has revealed that bottled water can contain complex mixtures of industrial chemicals never tested for safety, and may be no cleaner than tap water. Given some bottled water company's failure to adhere to the industry's own purity standards, Americans cannot take the quality of bottled water for granted. Indeed, test results like those presented in this study may give many Americans reason enough to reconsider their habit of purchasing bottled water and turn back to the tap."For these reasons, as well as environmental reasons (plastic bottles filling up dumpsites), I think it is becoming clearer and clearer that bottled water is something we should only use in a pinch, not habitually.
Can CRP be reduced? 13. November 2008 William Davis (17) The JUPITER study has sparked a lot of discussion about c-reactive protein, or CRP. If we follow the line of reasoning that prompted this study, reducing CRP may correlate with reduction of cardiovascular events. Thus, in the JUPITER study, Crestor 20 mg per day reduced cardiovascular events by nearly half. From a CRP perspective, starting values were 4.2 mg/dl in the Crestor group of the trial, 4.3 mg/dl in the placebo group. After 24 months, CRP in the Crestor group was 2.2 mg/dl, 3.5 mg/dl in the placebo group, representing a 37% reduction.Now, in our Track Your Plaque program--an experience that has yielded the virtual ELIMINATION of cardiovascular events--we aim for a CRP level of 1.0 mg/dl or less, ideally 0.5 mg/dl or less. The majority of people achieve these ambitious levels. In fact, it is a rare person who does not.How do we achieve dramatic reductions in CRP? We use:--Weight loss through elimination of wheat and cornstarch--This yields impressive reductions. --Vitamin D--I have no doubt whatsoever of vitamin D's capacity to exert potent anti-inflammatory effects. I am not entirely sure why this happens (enhanced sensitivity to insulin, reduced expression of tissue inflammatory proteins like matrix metalloproteinase and others, etc.), but the effect is profound. --Elimination of junk foods--like candies, cookies, pretzels, rice cakes, potato chips, etc. --Exercise--Amplifies the benefits of diet on CRP reduction. --Not allowing saturated fats to dominate--Yes, yes, I know. The demonization of saturated fat conversation has been largely replaced by the Taubesian saturated fat has not been confidently linked to heart disease conversation. But controlled feeding studies, in which a single component of diet is manipulated (e.g., saturated vs. monounsaturated vs. polyunsaturated fat) have clearly shown that saturated fats do activate several factors in the inflammatory response. --Fish oil--Though I am a firm believer in the huge benefits of omega-3 fatty acid supplementation/restoration, the anti-inflammatory effect is modest from a CRP perspective. However, there are anti-inflammatory benefits beyond that of simple CRP (via normalization of eicosanoid metabolism and other pathways). --Weight loss--A BIG effect. Weight loss drops CRP like a stone. The CRP-reducing effect is especially large if achieved via carbohydrate reduction. Of course, this is much more complicated than taking a pill. But it is effective to achieve health benefits outside of cardiovascular risk, is enormously useful as part of a weight loss effort, and doesn't cost $1400 per year like Crestor. In short, if CRP reduction is the goal, it certainly does not have to involve Crestor.
CRP and Jupiter 11. November 2008 William Davis (15) What is C-reactive protein (CRP)?It is a blood-borne protein that originates in the liver and serves as an index of the body's inflammatory state. It is triggered by yet another inflammatory signal molecule, interleukin-6. What triggers this cascade of inflammatory markers? Any inflammatory stimulus, such as being overweight, lack of exercise, vitamin D deficiency, viral illness no matter how trivial, any inflammatory disease like arthritis, small LDL, high triglycerides, poor diet rich in processed foods, resistance to insulin, any injury, incipient diabetes, hidden cancer, lack of education (no kidding), etc. In other words, many, many conditions, from trivial to serious, trigger increased inflammatory markers like CRP. A recent analysis (Genetically elevated C-reactive protein and ischemic vascular disease of persons with genetically elevated levels of CRP) suggests that CRP does not, by itself, cause atherosclerotic disease. CRP is therefore simply a marker for conditions that heighten inflammatory responses. The AstraZeneca people sponsored the enormous JUPITER study of the statin drug, Crestor, that has been causing a stir, mostly glowing pronouncements of how the world would be a better place if everyone took Crestor. In JUPITER, nealry 18,000 people (men 50 years and over, women 60 years and over) took 20 mg per day Crestor for two years. Participants all had starting LDL cholesterols in the "normal" range of no higher than 130 mg/dl and elevated CRP of 2 mg/dl or greater. Crestor treatment resulted in 44% reduction in nonfatal heart attack, nonfatal stroke, hospitalization for unstable angina, revascularization (bypass surgery, stents) and death from cardiovascular causes. The reduction in nonfatal heart attack was most marked at 55%. Admittedly, these are impressive results. Benefits held true for both males and females. At the very least, JUPITER should put to rest some of the fringe arguments that statins do not reduce cardiovascular events. They do. There is no sense in arguing against that. While we might argue about the value of statins in various subsets of people, there is no doubt that they do indeed exert a significant effect. However, contrary to the hype and broad pronouncements of my colleagues, my concerns are:1) Rather than shotgun the inflammatory response with a statin drug regardless of cause, doesn't it make more sense to ask why a specific individual has an increased CRP in the first place? For instance, if the answer is vitamin D deficiency, doesn't correction of the deficiency make more sense? (Vitamin D by itself reduces CRP around 60%--more than statin drugs.) Not to mention you obtain all the extraordinary benefits of vitamin D restoration, such as reduced cancer risk, increased bone density, relief from winter "blues," rise in HDL, etc. How about junk foods, obesity, and unrelated inflammatory conditions? Would we therefore indirectly be treating obesity with Crestor?2) Crestor 20 mg per day, contrary to the study and to many statin studies, will not be tolerated for long by the majority. Muscles aches are not common--they are inevitable, sometimes incapacitating. While JUPITER showed 15% of both treatment and placebo groups experienced muscle effects--no different--this is wildly contrary to real life. 3) While there was a 55% reduction in the number of heart attacks, there continued to be a substantial number of heart attacks in the Crestor treatment arm. Clearly, reduction of CRP with Crestor, while helpful, is not a cure.I view studies like JUPITER as simply an interesting piece of semi-scientific evidence, tainted to an unknown degree by commercial interests (including those of Dr. Paul Ridker, one of the principal investigators). It is not a mandate to use Crestor carte blanche in people with elevations of CRP. My interpretation of these data in a practical sense is that Crestor 20 mg per day as sole therapy is useful in a disinterested, non-compliant patient who is unwilling to make substantial changes in lifestyle and nutrition. Helpful? Yes, but hardly an invitation for the world to take Crestor. I believe that doesn't include any of the readers of this blog.
Nutritional approaches: Large vs. small LDL 11. November 2008 William Davis (13) It is now a rare person who does not have at least some proportion of their LDL cholesterol as small particles. I estimate that, of the people who come to the office or report their data on the Track Your Plaque website, 90% have at least 40-50% small LDL particles. Some people have 100% small LDL particles. The sample NMR lipoprotein report shows the result for someone with a severe small LDL pattern (the tallest red bar labeled 1354 nmol/L, compared to the 74 nmol/L of the tiny red bar of large LDL.) The nutritional approach for small vs. large LDL differs. Small LDL particles are most sensitive to carbohydrate intake; large LDL particles are more sensitive to saturated fats. The conventional "heart healthy" diet that restricts saturated fat reduces large LDL but exerts no effect on small LDL. Thus, a diet that is restricted in saturated fat and weighed more heavily with "healthy whole grains" triggers small LDL particles. Followers of the conversations here recognize that small LDL particles are flagrant triggers for coronary plaque; they have, in fact, become the number one most common cause for heart disease in the U.S. When you have lipoproteins tested, you can therefore gauge the likely result obtained when specific dietary changes are made. Follow the low saturated fat advice, large LDL will drop modestly, but small LDL skyrockets. (Image courtesy Liposcience, Inc.)Eliminate sugars, wheat, and cornstarch and you will see small LDL plummet (along with total LDL).As an aside, my personal observation is that the "need" for statin cholesterol drugs can be reduced dramatically by paying attention to this important LDL size distinction.
Factory hospitals 8. November 2008 William Davis (8) Twenty years ago, the American farming industry experienced a dilemma: How to grow more soybeans, corn, or wheat from a limited amount of farmland, raise more cattle and hogs in a shorter period of time, fatter and ready for slaughter within months rather than years? (Image courtesy Wikipedia)The solution: Synthetically fertilize farmland for greater crop yield; “factory farms” for livestock in which chickens or pigs are crammed into tiny cages that leave no room to turn, cattle packed tightly into manure-filled paddocks. As author Michael Pollan put it in his candid look at American health and eating, The Omnivore’s Dilemma:“To visit a modern Concentrated Animal Feeding Operation (CAFO) is to enter a world that for all its technological sophistication is still designed on seventeenth-century Cartesian principles: Animals are treated as machines—“production units”—incapable of feeling pain. Since no thinking person can possibly believe this anymore, industrial animal agr All posts by william-davis Toggle navigation Home Blog Home Archive Join Now Log in Large new clinical study launched to study. . .niacin 5. June 2006 William Davis (3) Oxford University has issued a press release announcing plans for a new clinical trial to raise HDL cholesterol and reduce heart attack risk. 20,000 participants will be enrolled in this substantial effort. The agent? Niacin.How is that new? Well, this time niacin comes with a new spin. Dr. Jane Armitage, formerly with the Heart Protection Study that showed that simvastatin (Zocor) reduced heart attack risk regardless of starting LDL, is lead investigator. She hopes to prove that niacin raises HDL cholesterol and thereby reduces heart attack risk. But, this time, niacin will be combined with an inhibitor of prostaglandins that blocks the notorious "flushing" effect of niacin. The majority of Track Your Plaque participants hoping to control or reverse coronary plaque take niacin. Recall that niacin (vitamin B3)is an extremely effect agent that raises HDL, dramatically reduces small LDL, shifts HDL particles into the effective large fraction, reduces triglycerides and triglyceride-containing particles like IDL and VLDL. Several studies have shown that niacin dramatically reduces heart attack. The HATS Study showed that niacin combined with Zocor yielded an 85-90% reduction in heart attack risk and achieved regression of coronary plaque in many participants.In our experience, approximately 1 in 20 people will really struggle using niacin. Flushes for these occasional people will be difficult or even intolerable. Should Dr. Armitage's study demonstrate that this new combination agent does provide advantages in minimizing the hot flush effect, that will be a boon for the occasional Track Your Plaque participant who finds conventional niacin intolerable. But you already have access to niacin, an agent with an impressive track record even without this new study. And you have a reasonably effective prostaglandin inhibitor, as well: aspirin. Good old aspirin is very useful, particularly in the first few months of your niacin initiation to blunt the flush. Although this study is likely to further popularize niacin and allow its broader use, it's also a method for the drug companies to profit from an agent they know works but is cheap and available. You don't have to wait. You already have niacin and aspirin available to you. The dark side of CT heart scans 4. June 2006 William Davis (0) "I just got a heart scan!" declared Eric to his doctor. He handed the report to him."Oh my. Your score is 154." The doctor paused, then looked at Eric with a serious look on his face. "If we're going to understand whether or not you're in danger, you'll need a heart catheterization."I've seen this happen countless times. How can I say this diplomatically? THIS IS WRONG!! In my view, it's absolutely criminal for this to happen. Physician ignorance, profiteering, whatever--it is wrong. There's very few reasons why someone who has no symptoms should go directly to the cath lab for a procedure. (A rare exception might be an exceptional quantity of plaque in the left mainstem artery, e.g., >100. This is highly unusual.)Even a nuclear stress test (e.g., thallium) at this level of scoring is only 10-15% likely to be abnormal. That means 85-90% likelihood of being normal. There's rare reasons to perform a heart catheterization in a person with no symptoms and an entirely normal stress test. The vast majority of people like Eric do not need a heart catheterization to discern risk. If Eric's doctor had been up-to-date on the published literature on the prognostic value of heart scans, he could have advised Eric what the risks were--without a catheterization. Many doctors simply don't want to be bothered. Or, they opt for the more profitable method--a hospital procedure.Always discuss your heart scan with your doctor--but be armed with information in case your doctor is uninformed or unscrupulous. Unfortunately, that's not uncommon. The Track Your Plaque program is your advocate, a source for unbiased information. The dirty little secret about aneurysms 2. June 2006 William Davis (1) Jake had an abdominal aneurysm identified--by accident. While getting a CT scan of his abdomen for unexplained abdominal pain, a 4.4 cm aneurysm was discovered. Jake's abdominal pain eventually passed without explanation, but he was left with this aneurysm.Jake's primary care doctor referred him to a surgeon. "It's too small to require surgery right now. Wait a few years and it'll probably get bigger. When it gets to around 5.5 cm, that'll be the time to operate. Let's schedule an abdominal ultrasound or CT scan every 6 months."Jake then got himself a heart scan. His high score of 879 then led him to my office. Lipoprotein testing, a stress test, correction of his lipoprotein patterns, changes in lifestyle followed. One year later, Jake's heart scan score was unchanged. How about his abdominal aneurysm? 4.2 cm--a modest quantity of regression. When Jake's surgeon learned of the change, he just shrugged. "Okay, we'll just watch it from here."Shockingly, the conversation surrounding aneurysms is just like the one Jake received: Let's just watch it grow until you need surgery. If you've every seen anyone have abdominal aneurysm surgery, you know it is an awful, painful, barbaric process with high risk for major complications like kidney failure and loss of the legs. Waiting for an aneurysm to grow is a lousy solution. Surgeons point out that, although surgery is imperfect, it's better than the alternative: rupture, which is catastrophic with a 50% chance of dying. But what about stopping the growth of the aneurysm? Or even reversing, or shrinking, it? Surgeons say it can't be done. Yet we've done it--many times. And it's not that difficult. The steps to take are very similar to that in the Track Your Plaque program for coronary plaque regression, with a few different strategies. Suppression of inflammation, for instance, plays a more important role and blood pressure must be abolutely normal, even during exercise. More to come on this important topic in the future, including an upcoming Special Report on the www.cureality.com membership website. Heart scan scores dropping like stones!! 1. June 2006 William Davis (0) I saw two instances of dramatic coronary plaque regression today. John, a 53-years old mechanical lift operator, dropped his heart scan score from 479 to 323--a 32% regression of coronary plaque volume! Eric, a 50-year consulting engineer, dropped his heart scan score from 668 to 580--a 13% reduction. Both men did nothing special beyond the principles advocated in the Track Your Plaque program. Recall that, without preventive efforts, your heart scan score is expected to increase by 30% per year. Both men are well on their way to freedom from risk of coronary "events". Two less people to feed the revenue-hungry hospital procedure system! We need many more like them. Pre-diabetes: An explanation for explosive coronary plaque growth 1. June 2006 William Davis (0) Art's first CT heart scan in March, 2006 yielded a concerning score of 1336. He felt fine--no chest discomfort, no breathlessness, etc. Art agreed to take the statin cholesterol drug his primary care doctor prescribed. He also agreed to take the fish oil, niacin, and some of the nutritional supplements that we advised. But Art just couldn't bring himself to make the commitment to lose weight. At the start of his program, Art--at 5 ft. 8 inches--was 40 lbs overweight (212 lb). This was important since his blood sugar wavered in the pre-diabetic range, going as high as 130 mg. (The American Diabetes Assn. defines diabetes as a blood glucose of 126 mg or greater.) One year later, Art's lipid and lipoprotein values were corrected to perfection. But he still weighed in at a hefty 209 lbs--essentially no change. His blood sugar likewise hovered in the 120's. I felt Art need to be prodded, so I asked him to undergo another heart scan. His score: 1935--a 600 point increase, or 45%! Only now has Art begun to comprehend to power of diabetes and pre-diabetes to fan the flames of plaque growth. Recent published data, in fact, show that the majority of recently diagnosed diabetics already have well-established coronary artery disease. Don't let this happen to you. Do not dismiss diabetic patterns as they will catch up to you. If Art can lose the 30-40 lbs in the abdominal weight that is creating the diabetic pattern, he will likely succeed in stopping plaque growth. Otherwise, it's just a matter of time before his heart attack, stent, or bypass. Who cares if you're pre-diabetic? 31. May 2006 William Davis (0) Marta is a smart lady. She's worked in hospital laboratories for the last 23 years and knows many of the ins and outs of lab tests and their implications. After years of being told that her cholesterol was acceptable, she needed to undergo urgent bypass surgery after experiencing severe breathlessness that proved to be a small warning heart attack at age 57. But this made Marta skeptical of relying on cholesterol to identify heart disease risk. I met Marta two years after her bypass surgery when she was seeking better answers. And, indeed, she proved to have several concealed sources of heart disease: small LDL particles, Lipoprotein(a), intermediate-density lipoprotein (IDL--a very important abnormality that means she is unable to clear dietary fats from her blood), among others. But she was also mildly diabetic with a blood sugar of 131 mg (normal < or = 100 mg). This had not been previously recognized. As I'm a cardiologist and our program focuses on reversal and control of coronary plaque, I asked Marta to return to her primary care doctor to continue the conversation about diabetes. She was a bit frightened but followed through. "Well, you're not urinating excessively. And your long-term measure of blood sugar, hemoglobin A1C, is still normal. I wouldn't worry about it. We'll just watch it."I guess I should know better. What the poor primary care doctor doesn't know is that pre-diabetes and mild diabetes are potent risks for heart disease. In fact, some of the most explosive rates of plaque growth occur when these patterns are present. It's well established that risk for heart attack in a diabetic is the same as that of someone who's already suffered a prior heart attack--very high risk, in other words.Marta's primary care doctor's advice would be like inquiring about cancer and the doctor says "Let's just wait until it's metastatic--then we'll start to worry." Of course, this is insane. Pre-diabetes and mild diabetes should not be ignored or just "watched". Even though the blood sugar itself may not be high enough to endanger you, the hidden patterns underlying your body's unresponsiveness to insulin creates a torrent of hidden coronary risk. For better answers, Track Your Plaque members can read "Shutting Off Metabolic Syndrome" at http://www.cureality.com/library/fl_dp001metabolic.asp on the www.cureality.com website. ("Metabolic syndrome" is the name commonly given to the constellation of abnormalities associated with pre-diabetes and diabetes.) Don't get smug! 31. May 2006 William Davis (2) It may sound silly, but after someone succeeds in stopping their heart scan score from increasing or reduces their score, I warn them to not get smug. Let me explain.I'll tell you about Jack. I met Jack a few years ago after he had a heart scan at age 39. His score: 1441! A score this high at his age obviously puts him in the 99th percentile. Also recall that a score >1000 carries a 25% annual risk for heart attack. This captured Jack's attention. At the start, his lipoproteins were disastrous with numerous abnormal patterns. Jack committed to the program. After one year, his lipoproteins were around 80-90% corrected towards perfection. He'd lost 27 lbs, was exercising six days a week, and felt great. Jack's repeat score one year later: 1107--over a 300 point drop! A huge success. He was ecstatic. Unfortunately, work and life in general distracted him. Jack allowed himself to drift back to old habits, indulging in fast food 2 or 3 times a week, slacking on exercise such that it became sporadic, half-hearted efforts, and regained 15 lbs. He even failed to show up for appointments and we lost contact for two years. One day, Jack simply decided to see where he stood, so he got himself another heart scan. The score: 2473--over a
Large new clinical study launched to study. . .niacin 5. June 2006 William Davis (3) Oxford University has issued a press release announcing plans for a new clinical trial to raise HDL cholesterol and reduce heart attack risk. 20,000 participants will be enrolled in this substantial effort. The agent? Niacin.How is that new? Well, this time niacin comes with a new spin. Dr. Jane Armitage, formerly with the Heart Protection Study that showed that simvastatin (Zocor) reduced heart attack risk regardless of starting LDL, is lead investigator. She hopes to prove that niacin raises HDL cholesterol and thereby reduces heart attack risk. But, this time, niacin will be combined with an inhibitor of prostaglandins that blocks the notorious "flushing" effect of niacin. The majority of Track Your Plaque participants hoping to control or reverse coronary plaque take niacin. Recall that niacin (vitamin B3)is an extremely effect agent that raises HDL, dramatically reduces small LDL, shifts HDL particles into the effective large fraction, reduces triglycerides and triglyceride-containing particles like IDL and VLDL. Several studies have shown that niacin dramatically reduces heart attack. The HATS Study showed that niacin combined with Zocor yielded an 85-90% reduction in heart attack risk and achieved regression of coronary plaque in many participants.In our experience, approximately 1 in 20 people will really struggle using niacin. Flushes for these occasional people will be difficult or even intolerable. Should Dr. Armitage's study demonstrate that this new combination agent does provide advantages in minimizing the hot flush effect, that will be a boon for the occasional Track Your Plaque participant who finds conventional niacin intolerable. But you already have access to niacin, an agent with an impressive track record even without this new study. And you have a reasonably effective prostaglandin inhibitor, as well: aspirin. Good old aspirin is very useful, particularly in the first few months of your niacin initiation to blunt the flush. Although this study is likely to further popularize niacin and allow its broader use, it's also a method for the drug companies to profit from an agent they know works but is cheap and available. You don't have to wait. You already have niacin and aspirin available to you.
The dark side of CT heart scans 4. June 2006 William Davis (0) "I just got a heart scan!" declared Eric to his doctor. He handed the report to him."Oh my. Your score is 154." The doctor paused, then looked at Eric with a serious look on his face. "If we're going to understand whether or not you're in danger, you'll need a heart catheterization."I've seen this happen countless times. How can I say this diplomatically? THIS IS WRONG!! In my view, it's absolutely criminal for this to happen. Physician ignorance, profiteering, whatever--it is wrong. There's very few reasons why someone who has no symptoms should go directly to the cath lab for a procedure. (A rare exception might be an exceptional quantity of plaque in the left mainstem artery, e.g., >100. This is highly unusual.)Even a nuclear stress test (e.g., thallium) at this level of scoring is only 10-15% likely to be abnormal. That means 85-90% likelihood of being normal. There's rare reasons to perform a heart catheterization in a person with no symptoms and an entirely normal stress test. The vast majority of people like Eric do not need a heart catheterization to discern risk. If Eric's doctor had been up-to-date on the published literature on the prognostic value of heart scans, he could have advised Eric what the risks were--without a catheterization. Many doctors simply don't want to be bothered. Or, they opt for the more profitable method--a hospital procedure.Always discuss your heart scan with your doctor--but be armed with information in case your doctor is uninformed or unscrupulous. Unfortunately, that's not uncommon. The Track Your Plaque program is your advocate, a source for unbiased information.
The dirty little secret about aneurysms 2. June 2006 William Davis (1) Jake had an abdominal aneurysm identified--by accident. While getting a CT scan of his abdomen for unexplained abdominal pain, a 4.4 cm aneurysm was discovered. Jake's abdominal pain eventually passed without explanation, but he was left with this aneurysm.Jake's primary care doctor referred him to a surgeon. "It's too small to require surgery right now. Wait a few years and it'll probably get bigger. When it gets to around 5.5 cm, that'll be the time to operate. Let's schedule an abdominal ultrasound or CT scan every 6 months."Jake then got himself a heart scan. His high score of 879 then led him to my office. Lipoprotein testing, a stress test, correction of his lipoprotein patterns, changes in lifestyle followed. One year later, Jake's heart scan score was unchanged. How about his abdominal aneurysm? 4.2 cm--a modest quantity of regression. When Jake's surgeon learned of the change, he just shrugged. "Okay, we'll just watch it from here."Shockingly, the conversation surrounding aneurysms is just like the one Jake received: Let's just watch it grow until you need surgery. If you've every seen anyone have abdominal aneurysm surgery, you know it is an awful, painful, barbaric process with high risk for major complications like kidney failure and loss of the legs. Waiting for an aneurysm to grow is a lousy solution. Surgeons point out that, although surgery is imperfect, it's better than the alternative: rupture, which is catastrophic with a 50% chance of dying. But what about stopping the growth of the aneurysm? Or even reversing, or shrinking, it? Surgeons say it can't be done. Yet we've done it--many times. And it's not that difficult. The steps to take are very similar to that in the Track Your Plaque program for coronary plaque regression, with a few different strategies. Suppression of inflammation, for instance, plays a more important role and blood pressure must be abolutely normal, even during exercise. More to come on this important topic in the future, including an upcoming Special Report on the www.cureality.com membership website.
Heart scan scores dropping like stones!! 1. June 2006 William Davis (0) I saw two instances of dramatic coronary plaque regression today. John, a 53-years old mechanical lift operator, dropped his heart scan score from 479 to 323--a 32% regression of coronary plaque volume! Eric, a 50-year consulting engineer, dropped his heart scan score from 668 to 580--a 13% reduction. Both men did nothing special beyond the principles advocated in the Track Your Plaque program. Recall that, without preventive efforts, your heart scan score is expected to increase by 30% per year. Both men are well on their way to freedom from risk of coronary "events". Two less people to feed the revenue-hungry hospital procedure system! We need many more like them.
Pre-diabetes: An explanation for explosive coronary plaque growth 1. June 2006 William Davis (0) Art's first CT heart scan in March, 2006 yielded a concerning score of 1336. He felt fine--no chest discomfort, no breathlessness, etc. Art agreed to take the statin cholesterol drug his primary care doctor prescribed. He also agreed to take the fish oil, niacin, and some of the nutritional supplements that we advised. But Art just couldn't bring himself to make the commitment to lose weight. At the start of his program, Art--at 5 ft. 8 inches--was 40 lbs overweight (212 lb). This was important since his blood sugar wavered in the pre-diabetic range, going as high as 130 mg. (The American Diabetes Assn. defines diabetes as a blood glucose of 126 mg or greater.) One year later, Art's lipid and lipoprotein values were corrected to perfection. But he still weighed in at a hefty 209 lbs--essentially no change. His blood sugar likewise hovered in the 120's. I felt Art need to be prodded, so I asked him to undergo another heart scan. His score: 1935--a 600 point increase, or 45%! Only now has Art begun to comprehend to power of diabetes and pre-diabetes to fan the flames of plaque growth. Recent published data, in fact, show that the majority of recently diagnosed diabetics already have well-established coronary artery disease. Don't let this happen to you. Do not dismiss diabetic patterns as they will catch up to you. If Art can lose the 30-40 lbs in the abdominal weight that is creating the diabetic pattern, he will likely succeed in stopping plaque growth. Otherwise, it's just a matter of time before his heart attack, stent, or bypass.
Who cares if you're pre-diabetic? 31. May 2006 William Davis (0) Marta is a smart lady. She's worked in hospital laboratories for the last 23 years and knows many of the ins and outs of lab tests and their implications. After years of being told that her cholesterol was acceptable, she needed to undergo urgent bypass surgery after experiencing severe breathlessness that proved to be a small warning heart attack at age 57. But this made Marta skeptical of relying on cholesterol to identify heart disease risk. I met Marta two years after her bypass surgery when she was seeking better answers. And, indeed, she proved to have several concealed sources of heart disease: small LDL particles, Lipoprotein(a), intermediate-density lipoprotein (IDL--a very important abnormality that means she is unable to clear dietary fats from her blood), among others. But she was also mildly diabetic with a blood sugar of 131 mg (normal < or = 100 mg). This had not been previously recognized. As I'm a cardiologist and our program focuses on reversal and control of coronary plaque, I asked Marta to return to her primary care doctor to continue the conversation about diabetes. She was a bit frightened but followed through. "Well, you're not urinating excessively. And your long-term measure of blood sugar, hemoglobin A1C, is still normal. I wouldn't worry about it. We'll just watch it."I guess I should know better. What the poor primary care doctor doesn't know is that pre-diabetes and mild diabetes are potent risks for heart disease. In fact, some of the most explosive rates of plaque growth occur when these patterns are present. It's well established that risk for heart attack in a diabetic is the same as that of someone who's already suffered a prior heart attack--very high risk, in other words.Marta's primary care doctor's advice would be like inquiring about cancer and the doctor says "Let's just wait until it's metastatic--then we'll start to worry." Of course, this is insane. Pre-diabetes and mild diabetes should not be ignored or just "watched". Even though the blood sugar itself may not be high enough to endanger you, the hidden patterns underlying your body's unresponsiveness to insulin creates a torrent of hidden coronary risk.
