Can natural treatments "cure" or "treat" any disease? 30. August 2006 William Davis (0) According to current FDA policy, the answer is a flat "NO!" No natural treatment, whether it be fish oil (as a nutritional supplement), l-arginine, vitamin D, magnesium, various flavonoids like theaflavin or resveratrol, can be declared to treat or cure any disease. That's why you see the evasive and vague wording on nutritional supplements, nutraceuticals, and various foods, like "Supports heart health" or "Supports healthy cholesterol". Claiming, for instance, that taking 6000 mg per day of a standard OTC fish will reduce triglycerides and stating so on the label of a supplement is unlawful and prosecutable. Think what you will of Mr. Kevin Trudeau (author of Natural Cures They Don't Want You to Know About"): visionary, consumer advocate, David vs. the Goliath of the FDA and "Big Pharma", or huckster, scam artist, and one-time felon. But Trudeau got it right on one important issue: The FDA dictates what claims can be made to treat disease. On one of his ubiquitous informercials, Trudeau states:"...the way the system works today, you have the Food and Drug Administration—the FDA, and you have the drug industry. They really work in tandem. Unfortunately, there’s an unholy alliance there. People don’t know that the majority of commissioners of the FDA, which allegedly regulates the drug industry, and the food industry—Food and Drug Administration, the commissioners of the FDA—the majority of them—go to work directly for the drug companies upon leaving the FDA and are paid millions and millions and millions of dollars. Now in any other format, that would be called bribery; that would be called a conflict of interest; that would be called payoffs. That’s exactly what’s happening right now. So what has occurred is the Food and Drug Administration is really working in tandem with the drug industry to protect their profits. Example: The Food and Drug Administration says that only a drug can diagnose, prevent, or cure any disease."He goes on to say that "...the Food and Drug Administration says only a drug--nothing else--can cure, prevent, or diagnose a disease. Therefore the Food and Drug Administration continues to call more and more and more things diseases. Therefore they eliminate all-natural remedies. No one can say what a natural remedy can do if it’s been classified as a disease. So Attention Deficit Disorder is now a disease. Therefore only a drug can cure, prevent, or diagnose it. Cancer is a disease. Acid reflux is now a disease. Obesity is now a disease."(PLEASE do not construe this as an endorsement of Mr. Trudeau's overall opinions. But I do think he's right on this one point.) The stated purpose of this restrictive policy is to protect the public. Indeed, in years past before protective legislation, ineffective and even poisonous products were commonly sold as therapeutic treatments. (Remember cocaine and morphine in cold remedies? Lead and other toxic agents were also common.) Unfortunately, a huge gap has emerged as clinical data accumulates that support the efficacy of nutritional treatments and other non-traditional methods to treat or alleviate diseases. Any disease, or anything construed as disease as Trudeau points out, can onlybe treated by a drug. In the FDA's defense, they have made slow progress in allowing "claims" of benefits for several supplements and food substances, such as the beta-glucan of oat products, soy protein, and most recently barley (for cholesterol reduction). The scrutiny is quite thorough and the wording of the policy is quite specific. Regarding oat products, for instance, the policy states: "FDA concluded that the beta-glucan soluble fiber of whole oats is the primary component responsible for the total and LDL blood cholesterol-lowering effects of diets that contain these whole oat-containing foods at appropriate levels. This conclusion is based on review of scientific evidence indicating a relationship between the soluble fiber in these whole oat-containing foods and a reduction in therisk of coronary heart disease.Food products eligible to bear the health claim include oat bran and rolled oats, such as oatmeal, and whole oat flour...To qualify for the health claim, the whole oat-containing food must provide at least 0.75 grams of soluble fiber perserving. The amount of soluble fiber needed for an effect on cholesterol levels is about 3 grams per day."(Source: FDA Talk Paper which can be viewed in its entirety at http://www.fda.gov/bbs/topics/ANSWERS/ANS00782.html.)In light of the boom in nutritional and non-traditional research that validate or refute efficacy, is such a policy still necessary? Or does it inhibit the open dissemination of information and result in a extraordinary monopolization of health treatment for the drug companies? This debate will likely rage for the next two or more decades, particularly as drug companies are increasingly viewed as profit-seeking enterprises and more validation is gained by non-drug treatments. For the moment, don't dismiss a "treatment" because it doesn't come by prescription. But don't reject a drugjust because it is a prescription. We need to strike a healthy, rational balance somewhere in between.
Can procedures alone keep you alive? 29. August 2006 William Davis (0) My days in the hospital remind me of what heart disease can be like when no preventive efforts are taken--what it used to be like even with my patients before taking a vigorous approach to prevention (though over 12 years ago). Several cardiologists in my hospital, for instance, express skepticism that heart disease prevention works at all. Yes, they know about the statin cholesterol drug trials. But they claim that, given their experience with the power of coronary disease to overpower an individual's control, statin drugs are just "fluff". Coronary disease is a powerful process that can only begin to be harnessed with major procedures, i.e., a mechanical approach. So these cardiologists routinely have their patients in the hospital, often once a year, sometimes more, for heart catheterization and "fixing" whatever requires fixing: balloon angioplasty, stents, various forms of atherectomy. Year in, year out, these patients return for their "maintenance" procedures. Their cardiologists maintain that this approach works. The patients go on eating what they like, taking little or no nutritional supplements, and medications prescribed by their primary care physicians for blood pressure, etc. But no real effort towards heart disease prevention beyond these minimal steps.Can this work? Very little at-home, preventive efforts, but periodic "maintenance" procedures? It can, perhaps, for a relatively short time of a few years, maybe up to 10 years. But it crumbles after this. The disease eventaully overwhelms the cardiologist's ability to stent or balloon this or that, since it has progressed and plaque has growth diffusely the entire period that maintenance procedures have been performed. In addition, acute illness still occurs with some frequency--in other words, plaque rupture is not affected just because there's a stent in the artery upstream or downstream.Not to mention this can be misery on you and your life, with risk incurred during each procedure. It's also terribly expensive, with hospitalization easily costing $25,000-$50,000 or more each time. (Compare that to a $250 or so CT heart scan.)As people become more aware of the potential tools for prevention of heart disease, fewer are willing to submit to the archaic and barbaric practice of "maintenance" heart procedures in lieu of prevention. But it still goes on. If you, or anybody you know, are on this pointless and doomed path, find a new doctor.Bloodletting, another antiquated health practice
Support your local hospital: HAVE A HEART ATTACK! 25. August 2006 William Davis (0) I'm kidding, of course. But, in your hospital's secret agenda, that's not too far from the truth. Catastrophes lead to hospital procedures, which then yields major revenues. Prevention, on the other hand, yields nothing for your hospital. No $8,000 to $12,000 for heart catheterization, several thousand more for a stent, $60,000-plus for a bypass, $25,000 or more for a defibrillator. In other words, prevention of heart attack and all its consequences deprive your hospital of a goldmine of revenue. The doctors are all too often conspirators. I heard of yet another graphic example today. A man I didn't know called me out of the blue with a question. "I had a heart scan and I had a 'score' that I was told meant a moderate quantity of plaque in my arteries, a score of 157. My doctor said to ignore it. But I got another scan a year later and my score was 178. So I told this to my doctor and he said, 'Let's get you into the hospital. We'll set up a catheterization and then you'll get bypassed.' Of course, I was completely thrown off balance by this. Here I was thinking that the heart scan was showing that my prevention program needed improvement. But my doctor was talking about bypass surgery. Can you help? Does this sound right?"No, this is absolutely not right. It's another tragedy like the many I hear about every day. Heart scans are, in fact, wonderfully helpful tools for prevention. This man was right: he felt great and the heart scan simply uncovered hidden plaque that should have triggered a conversation on how to prevent it from getting worse. But the doctor took it as a license to hustle the patient into the hospital. Ka-ching!This sort of blatant money-generating behavior is far from rare. Don't become another victim of the cardiovascular money-making machine. Be alert, be skeptical, and question why. Of course, there are plenty of times when major heart procedures are necessary. But always insist on knowing the rationale behind such decisions, whether it's you or a loved one.
Hospitals contain experts in ILLNESS 25. August 2006 William Davis (0) Hospitals contain many experts in sickness. This seems obvious. But walk down the hallways of any hospital, and you'll quickly be convinced that hospitals contain almost no experts in health. People (hospital staff, that is, not the patients) in hospitals are especially good at identifying and treating disease. They lack knowledge of health. If your nurse is 100 lbs overweight and struggles to walk down the hall because of arthritis in both knees, would you entrust her with health advice?If your doctor sits down in the cafeteria and eats his lunch of a ham sandwich with cheese on a bun, fried onion rings, and a milkshake and pastry, can you believe that he/she possesses any insight into health and nutrition?If your physical therapist or cardiac rehabilitation counselor struggles nearly as much as you while climbing a single flight of stairs, can you accept their advice on how to regain your stamina and use exerise to full health advantage? The answer to all these questions is, of course, no. Hospital staff are generally expert at dressing surgical wounds, stopping bleeding, identifying infections, and providing the support services for surgical and diagnostic procedures. In contrast, they are generally miserable at conveying genuine health advice. They certainly fall short in being examples of health themselves. To hospitals and their staff, health is a temporary situation that persists only until you become ill. Illness is an inevitability in the hospital staff mindset. Health is a temporary state in between illnesses. We need to shake off this perverse mentality. Health is the state of life that should dominate our practices and philosophies. Illness via the occasional catastrophe, e.g., broken leg from skiing, car accident, etc., is the province of hospitals. We should gravitate towards this philosphy and away from the over-reliance on hospitals that has come to dominate our present perceptions of health. Hospitals are not glamorous. They are, for the most part, profit-seeking businesses intent on portraying themselves as champions of health. When I walk down the halls of hospitals, I am shocked and ashamed at the extraordinary examples of ill-health presented by hospital staff. Yet they falsely paint themselves as experts in both illness and health. Don't believe it for a second.
Are there still unexplored causes of heart disease? 23. August 2006 William Davis (0) I met a woman today. She had her first heart attack at age 37. She just had her 2nd heart attack this morning, at age 40. Several issues are surprising about her story. First, she's pre-menopausal. Heart attacks before menopause are unusual. We'll occasionally see women have a heart attack before or during menopausal years only if they're heavy smokers and/or they have had diabetes (either type I or type II) for many years. But this young woman had neither. She is slender and has never smoked. Even more surprising are her basic lipid values: LDL cholesterol 35 mg/dl, HDL 150 mg/dl, triglycerides 317 mg/dl. This is a very unusual pattern. Unfortunately, this is all developing acutely in the hospital. (I've just met her today--she's not a Track Your Plaquer!) Lipoprotein analysis would be extremely interesting. In particular, I'd like to see whether she has any other markers besides elevated triglycerides of a "post-prandial" abnormality, i.e., persistence of abnormal particles after eating. The high triglycerides make this quite likely. If this proves true, the omega-3 fatty acids from fish oil will be a lifesaving treatment for her, since they dramatically reduce both triglycerides as well as persistent postprandial particles like intermediate-density lipoprotein (IDL). (Track Your Plaque Members: See the Special Report on Postprandial Abnormalities on the present home page at www.cureality.com for a more in-depth discussion of this fascinating collection of patterns that is just started to be explored.) In the real world, especially acute care medicine, there's always a kicker: she speaks no English. Unfortunately, communicating the intricacies of a powerful program like ours that aims to identify all causes of heart disease, then corrects then and aims for coronary plaque regression, is difficult if not impossible. I also do occasionally worry that, given this woman's extraordinary risk at a young age, and overall very unusual lipid patterns (HDL 150?!), if there are causes presently beyond our reach. We have to make use of the tools available to us for now.
Everything causes heart attack! 22. August 2006 William Davis (1) The media are presently gushing about a recent study that associates caffeine intake with heart attack. CBS News: That cup of coffee you're craving might not be such a good idea. Research in the September issue of Epidemiology suggests coffee can trigger a heart attack within an hour in some people. Some reporters and their quoted sources are musing about whether it's the caffeine, cream vs. other whiteners, time of day, interaction with other risk factors, etc. My advice: Get a grip! How many relatively benign, every day factors in life can be blamed for dire health risks? The problem with many of these studies is that they are cross-sectional. They do not enroll participants, then "treat" with coffee (or other substance in question) vs. placebo. In other words, it is not a randomized trial, the sort of trial necessary to prove a hypothesis. That's all that can be generated by a study like this one: a hypothesis.Perhaps there's a bit of warning for the person with uncorrected lipids and lipoproteins, has no idea that they have extensive coronary plaque because they've never had a heart scan, and have a slovenly lifestyle. Maybe that person might have exaggerated risk from a cup of coffee. But for us, involved and intensively addressing all causes of coronary plaque to the point of stabilizing or reducing it, coffee is likely a non-issue.

Excessive Heart Procedures Makes New York Times Headline 18. August 2006 William Davis (0) One example of flagrant cardiac procedure excess has made New York Times headlines:Heart Procedure Is Off the Charts in an Ohio City The number of angioplasties performed in Elyria is so high that Medicare is starting to ask questions.(The full article can be accessed through the New York Times website at http://www.nytimes.com/2006/08/18/business/18stent.html?pagewanted=2&ei=5094&en=b81be5f43f98a99b&hp&ex=1155960000&partner=homepage)Cardiologists in little Elyria, Ohio, about a 30-minute drive west of Cleveland, do more coronary angioplasties and insert more stents than any other location in the U.S.--four times more than the national average, three times more than the Cleveland average. They perform even more than the recently-indicted cardiologist in Louisiana, who performed twice the national average of procedures.The Times article, part of a series about financial incentives in medical care, provides a responsible and incredibly balanced report on the situation in Elyria. I have to give them credit, because from the eyes of a colleague (myself), this looks like blatant and extreme profiteering: "cathing for dollars". I find it outrageous that this group of cardiologists claims that they have some special insight into heart care that justifies this extraordinary reliance on heart procedures. There's bound to be variation in practice patterns, but this is so outside the norm that I believe criminal behavior will be exposed. In fact, I believe that even the "norm", or average, rate of procedures is also excessive. This is symptomatic of the perverse equation in heart disease care. If there's money to be made in major heart procedures, who wants to bother with prevention? Programs like the Track Your Plaque program present real potential to stop coronary heart disease in its tracks for many, if not most, participants--but don't expect to hear about it from your cardiologist. Don't expect to hear about it from the increasingly hospital-employed primary care physician. Hopefully, media exposure like that in the New York Times is just the beginning of a public re-analysis of not only what's wrong with medicine today, but recognition of the tremendous power in preventive strategies when everyone stops being so enamored with hospital-based procedures. CT-based heart scanning that ignites your heart disease prevention program is your way to dodge the mainstream obsession with procedures.
More on "Bio-identical hormones" and Wyeth Pharmaceuticals 18. August 2006 William Davis (0) In October 2005, Wyeth petitioned the FDA, requesting that it completely ban the bioidentical alternatives that women have been using in ever-increasing numbers to achieve optimal hormone balance. With bioidentical replacement therapy clearly reducing its market share, Wyeth asked the FDA to outlaw all compounded bioidentical hormone formulations that compete with its own discredited drugs. If Wyeth is successful, then menopausal women will have no choice other than to take potentially life-threatening hormone drugs or to forgo hormone replacement therapy altogether, thus enduring the physically and emotionally debilitating effects of menopause-induced hormone depletion. Dave TuttleLife Extension MagazineAugust, 2006For more commentary on Wyeth Pharmaceutical's outrageous and brazen petition to the FDA to bar prescription "bio-identical" hormones, i.e., hormones that are identical to natural human forms, read Life Extension's article, Health Freedom Under Attack!Drugmaker Seeks to Deny Access to Bioidentical HormonesThis well-researched article is in the August, 2006 issue of Life Extension Magazine. The article can also be accessed online at http://www.lef.org/magazine/mag2006/aug2006_cover_attack_01.htmor go to www.lef.org and click on the August, 2006 issue. The author, Dave Tuttle, details the baseless arguments raised by Wyeth, a pathetic and amazingly selfish act in the name of protecting profits for Premarin, their prescription agent. It's bad enough to be selling this worthless drug. It's even worse--criminal, in my mind--to try to stamp out our right to have a physician write a prescription for a pharmacy to mix up hormones identical to that humans produce, individualized to our needs. If you are as angry about this as I am, please go to the Life Extension online reprint that provides access to the International Academy of Compounding Pharmacists website to send the FDA an e-mail describing your opinion, or go to www.iacprx.org.
How accurate is LDL cholesterol? 17. August 2006 William Davis (0) Watch TV and you'd get the impression that the world revolves around LDL cholesterol: Commercials for Lipitor, Zetia, Vytorin, etc., all drugs to reduce cholesterol (total and LDL). Your doctor looks first and often only at LDL cholesterol. If there's so much attention paid to LDL, how accurate is it? 100%? 90%? 80%?Well, it varies widely. Occasionally, it's truly accurate, but most of the time it's miserably inaccurate . Every single day, I see people with LDL cholesterols that underestimates true (measured) LDL by 40%, 50%, and even over 100%. In other words, LDL cholesterol might be 120 mg/dl by the conventional method, but the genuine measured value might be 160 mg/dl, or even 240 mg/dl. It can be that far off--and it's not rare.The converse can occasionally be true, though rarely in my experience: that conventional LDL overestimates true LDL. I saw someone in the office today like this, with a conventional LDL of 142 mg/dl but a true measured LDL of 115 mg/dl. I may see one or two more people like this the rest of this year. Why is LDL so inaccurate? Several reasons:--LDL in most labs is calculated, not measured. The "Friedewald calculation" derives LDL by substracting HDL and triglycerides (divided by 5) from total cholesterol. The higher triglycerides are, especially above 150 mg/dl, the more inaccurate the calculation becomes. As HDL drops below 50 mg/dl, this also introduces greater and greater inaccuracy. --LDL particles vary in size. A more accurate representation and measure of LDL's dangers are therefore found in measures of LDL particle number , rather than a weight-based measure or calculation. LDL particle number can be measure as just that, LDL particle number (NMR), or as apoprotein B, the protein in LDL that occurs one apoB per LDL. I liken conventionally calculated LDL cholesterol to a broken speedometer. You simply won't have an accurate measure of how fast you're going, though you may have a ballpark sense. But try telling that to the state patrol. Or, as a cardiologist colleague said to me in a similar conversation about LDL: "Well, it's better than nothing!"The lesson: If you're interested in plaque control, and control or reduction of heart scan score, you need a measured LDL, preferably LDL particle number by NMR or an apoprotein B. Another option is "direct" LDL.
Green tea: friend or faux? 15. August 2006 William Davis (0) The www.HealthCastle.com website is a helpful website on healthy eating that sends out a free newsletter. The content is all produced by licensed dietitions and nutritionists. Although I don't agree with everything said on the site, there's still some good information. I'm a fan of green tea. Although I believe the effects are relatively modest (weight reduction, cholesterol reduction, anti-oxidation, etc., with theaflavin and/or green tea as a beverage,) they alerted me to the fact that the Lipton Green Tea product is one you should steer clear of. Here are their comments: Toggle navigation Home Blog Home Archiv Join Now Reguläre Seite Anmelden The Track Your Plaque guide to getting grotesquely overweight 15. August 2006 William Davis (0) If you'd like to gain huge quantities of weight, here's a number of helpful tips:1) Follow the advice of food manufacturers and eat the products they label "healthy", or "heart healthy", or "part of a nutritious breakfast" etc., like Shredded Wheat cereal, pretzels ("a low-fat snack"!), low- or non-fat salad dressings. 2) Cut your morning calorie intake by skipping breakfast.3) Hang around with other heavy people. They will confirm that it's okay to be overweight. 4) Call walking your dog "exercise". 5) Get a sedentary desk job. Use your swivel desk chair to scoot about whenever possible, rather than getting up to do things. 6) Say "I've worked hard all week long. Weekends are for relaxing, not for physical activities. I deserve a rest."7) Eat foods without thinking about it: Eat chips while watching football, eat while on the phone, daydream over the sink.8) Eat to provide comfort when stressed.9) Eat foods that have sentimental value, whether or not they're good for you: Freshly-baked cakes that remind you of Mom, Pop Tarts that you used to carry in your lunchbox when you were a kid, hot dogs just like Dad would buy at the baseball stadium. 10) Cut back on sleep and generate insatiable starch cravings.11) Stack your shelves at home with great variety. That way, you'll always have something to suit your mood. 12) Say to your spouse: "It's none of your damn business what I eat! I'm a grown man/woman!" Prove it by over-indulging in obviously unhealthy foods. 13) Tell yourself that you're just too busy to pay attention to food choices. Just grab whatever you can out of a convenience store or vending machine. See, it's easy! And that just a start.Of course, I don't really want you to do any of these things. But if you see yourself in any of the above, and you're struggling with weight, you should seriously rethink your approach. Your heart scan is just a "false positive" 15. August 2006 William Davis (0) I've seen this happen many times. Despite the great media exposure and the growing acceptance of my colleagues, heart scans still trigger wrong advice. I had another example in the office today.Henry got a CT heart scan in 2004. His score: 574. In his mid-50s, this placed him in the 90th percentile, with a heart attack risk of 4% per year. Henry was advised to see a cardiologist. The cardiologist advised Henry, "Oh, that's just a 'false positive'. It's not true. You don't have any heart disease. Sometimes calcium just accumulates on the outside of the arteries and gives you these misleading tests. I wish they'd stop doing them." He then proceeded to advise Henry that he needed a nuclear stress test every two years ($4000 each time, by the way). No attempt was made to question why his heart scan score was high, since the entire process was outright dismissed as nonsense. I'm still shocked when I hear this, despite having heard these inane responses for the past decade. Of course, Henry's heart scan was not a false positive, it was a completely true positive. I'm grateful that nothing bad happened to Henry through two years of negligence, though his heart scan score is likely around 970, given the expected, untreated rate of increase of 30%. The cardiologist did a grave disservice to Henry: He misled him due to his ignorance and lack of understanding. I wish Henry had asked the cardiologist whether he had read any of the thousands of studies now available validating CT heart scans. I doubt he's bothered to read more than the title. The cardiologist is lucky (as is Henry) that nothing bad happened in those two years.Do false positives occur as the cardiologist suggested? They do, but they're very rare. There's a rare phenomenon of "medial calcification" that occurs in smokers and others, but it is quite unusual. >99% of the time, coronary calcium means you have coronary plaque--even if the doctor is too poorly informed to recognize it. What's better than a heart scan? 13. August 2006 William Davis (0) Do you know what's better than a heart scan?Two heart scans. No other method can provide better feedback on the results of your program. Say you've made efforts to correct high LDL; lost weight to raise HDL and reduce small LDL; added soluble fibers, nuts, and dramatically reduced wheat products; take fish oil, vitamin D, and follow a flavonoid-rich diet. Has it worked? After a year or so of your program, that's when another heart scan can give you invaluable feedback on whether it's been successful. I tell my patients that it's relatively easy to correct lipid and lipoprotein abnormalities. The difficult part is to know when it's good enough. Is your LDL of 67 mg/dl and HDL of 50 mg/dl good enough? Another heart scan score is the best way I know of to find out. Variation in plaque growth differs hugely from one person to another, even at equivalent lipoprotein values. Why? Lots of reasons. Humans are inconsistent day to day. Lipoproteins, being a snapshot in time and not a cumulative value, change somewhat from day to day. There's also the possibility of unmeasured, unrecognized factors that influence coronary plaque growth. We may not be smart enough to identify these hidden factors yet. But your heart scan score will incorporate the effects of these hidden factors.Ideally, we aim for zero growth in plaque (no change in score) or a reduction. But, particularly in the first year, 10% or less plaque growth is still a good result that predicts much reduced risk of heart attack. More than 20% per year and your program needs more work--or else you know what's ahead. Lipids are snapshots in time; heart scans are cumulative 12. August 2006 William Davis (0) Let me paint a picture. It's fictional, though a very real portrait of how things truly happen in life. Michael is an unsuspecting 40-year old man. He hasn't undergone any testing: no heart scan, no lipids or lipoproteins. But we have x-ray vision, and we can see what's going on inside of him. (We can't, of course, but we're just pretending.) Average build, average lifestyle habits, nothing extraordinary about him. His lipids/lipoproteins at age 40:--LDL cholesterol 150 mg/dl--HDL cholesterol 38 mg/dl--Triglycerides 160 mg/dl--Small LDL 70% of all LDLAt age 40, with this panel, his heart scan score is 100. That's high for a 40-year old male. Fast forward 10 years. Michael is now 50 years old. Michael prides himself on the fact that, over the past 10 years, he's felt fine, hasn't gained a single pound, and remains as active at 50 as he did in 40. In other words, nothing has changed except that he's 10 years older. His lipids and lipoproteins:--LDL cholesterol 150 mg/dl--HDL cholesterol 38 mg/dl--Triglycerides 160 mg/dl--Small LDL 70% of all LDLSome of you might correctly point out that just simple aging can cause some deterioration in lipids and lipoproteins, but we're going to ignore these relatively modest issues for now.)Lipids and lipoproteins are, therefore, unchanged. Michael's heart scan score: 1380, or an approximate 30% annual increase in score. (Since Michael didn't know about his score, he took no corrective/preventive action.)My point: If we were to make our judgment about Michael's heart disease risk by looking at lipids or lipoproteins, they would'nt tell us where he stood with regards to heart disease risk. His lipids and lipoproteins were, in fact, the same at age 50 as they were at age 40. That's because measures of risk like this are snapshots in time. In contrast, the heart scan score reflects the cumulative effects of life and lipids/lipoproteins up until the day you got your scan. Which measure do you think is a better gauge of heart attack risk? I think the answer's obvious. 11. August 2006 William Davis (0) The recognition of the metabolic syndrome as a distinct collection of factors that raise heart disease risk has been a great step forward in helping us understand many of the causes behind heart disease. Curiously, there's not complete agreement on precisely how to define metabolic syndrome. The American Heart Association and the National Heart, Lung, and Blood Institute issued a concensus statement in 2005 that "defined" metabolic syndrome as anyone having any 3 of the 5 following signs:Waist size 40 inches or greater in men; 35 inches or greater in women Triglycerides 150 mg/dL or greater (or treatment for high triglycerides) HDL-C <40 mg/dL in men; <50 mg/dL in women (or treatment for reduced HDL-C) Blood Pressure >130 mmHg systolic; or >85 mmHg diastolic (or drug treatment for hypertension) Glucose (fasting) >100 mg/dL (or drug treatment for elevated glucose) Using this definition, it has become clear that meeting these criteria triple your risk of heart attack. But can you have the risk of metabolic syndrome even without meeting the criteria? What if your waste size (male) is, 36 inches, not the 40 inches required to meet that criterion; and your triglycerides are 160, but you meet none of the other requirements? In our experience, you certainly can carry the same risk. Why? The crude criteria developed for the primary practitioner tries to employ pedestrian, everyday measures. We see people every day who do not meet the criteria of the metabolic syndrome yet have hidden factors that still confer the same risk. This includes small LDL; a lack of healthy large HDL despite a normal total HDL; postprandial IDL; exercise-induced high blood pressure; and inflammation. These are all associated with the metabolic syndrome, too, but they are not part of the standard definition. I take issue in particular with the waist requirement. This one measure has, in fact, gotten lots of press lately. Some people have even claimed that waist size is the only requirement necessary to diagnose metabolic syndrome. Our experience is that features of the metabolic syndrome can occur at any waist size, though it increases in likelihood and severity the larger the waist size. I have seen hundreds of instances in which waist size was 32-38 inches in a male, far less than 35 inches in a female, yet small LDL is wildly out of control, IDL is sky high, and C-reactive protein is markedly increased. These people obtain substantial risk from these patterns, though they don't meet the standard definition. To me, having to meet the waist requirement for recogition of metabolic syndrome is like finally accepting that you have breast cancer when you feel the two-inch mass in your breast--it's too late. Recognize that the standard definition when you seen it is a crude tool meant for broad consumption. You and I can do far better. What role DHEA? 9. August 2006 William Davis (2) DHEA, the adrenal gland hormone, has suffered its share of ups and downs over the years. Initially, DHEA was held up as the fountain of youth with hopes of turning back the clock 20 years. Such extravagant dreams have not held up. But DHEA can still be helpful for your program. All of us had oodles of DHEA in our bodies when we were in our 20s and 30s. Gradually diminishing levels usually reach nearly blood levels of around zero by age 70. In our heart disease prevention program, of course, we aim to stop or reduce your CT heart scan score. Does DHEA reduce your score? No, it most certainly does not. But it can be helpful for gaining control over some of the causes behind coronary plaque. For instance, DHEA can:--Help reduce abdominal fat and increase muscle mass (slightly)--Provide more physical stamina. --Boost mood.--It may modestly reduce some of the phenomena associated with the metabolic syndrome (high blood pressure, high blood sugar, high insulin, low HDL, small LDL, etc.)In my experience, people who feel better do better on their overall program. If you're always tired and run down and run out of steam by 3 pm, I won't see you riding your bicycle outdoors or at the aerobics class. But if you're bursting with energy until you put your head on the pillow, you're more inclined to walk, bike, dance, play with the kids, dance, take Tai Chi, etc. Some downsides to DHEA: Some people experience aggression. Backing off on the dose usually relieves it. Also, sleeplessness. Taking your DHEA in the morning usually fixes it. The dose is best tailored to your age and blood levels. People less than 40 years old should not take DHEA. The older you are, the higher the dose, though we rarely ever have to exceed 50 mg per day. If you've never had a blood level and your doctor refuses to obtain one, 25 mg per day is a reasonable dose (10-15 mg in women 40-50 years old). It's always best to discuss your supplement use, particularly agents like DHEA, with your doctor.

August 2006 William Davis (0) At a social gathering this weekend, as we humans like to do, someone asked me what I did for a living. I told him I was a cardiologist. "What hospital do you work at?" he asked. This is invariably the response I get whenever I tell people what I do. I wouldn't make much of it except that it happens just about every time. This indicates to me just how successful hospitals, my colleagues, cardiac device manufacturers, and others supporting the status quo in heart care, have been in persuading us that the place for heart disease is the hospital--period. Tense families, drama, high-tech...It all takes place in the hospital. Yet the people destined to be the fodder for hospital heart care are presently well, mostly unaware of what the future holds. Also unaware that heart disease is readily, easily, inexpensively, and accurately identifiable. Ask anyone in the Track Your Plaque program who's had a CT heart scan. We all need to rid ourselves of the idea that the hospital is the place for heart disease. If the coronary plaque behind heart attack is easy to detect and controllable, there's little or no need for the hospital for the vast majority of us.In the majority of instances of coronary disease, the hospital should be the place for the non-compliant and the ill-informed, and not for those of us sufficiently motivated to know and do better. The formula is simple: 1) Quantify plaque with a CT heart scan, 2) Identify the causes, then 3) Correct the causes. The Fanatic Cook: A fabulous Blog about food and nutrition 7. August 2006 William Davis (0) I came across this Blog authored by a nutritionist when it was highlighted on Blogger as an interesting site:The Fanatic Cook at http://fanaticcook.blogspot.com/I was thoroughly impressed with the insightful and entertaining commentary. I'd highly recommend this site to you for reading on nutrition. In particular, her coenzyme Q10 column was exceptionally well written and clear.(http://fanaticcook.blogspot.com/2005/02/statins-and-not-well-publicized-side.html)Also read her column, Super NonFoods at http://fanaticcook.blogspot.com/2005/07/super-nonfoods.html.There's also oodles of recipes, all for the taking. Eggs: Good, bad, or indifferent? 5. August 2006 William Davis (3) Eggs have been in the center of the cholesterol controversy almost from the very start. The traditional argument against eggs went that eggs, high in cholesterol (210-275 mg per egg)and with some saturated fat (1.5-2.5 grams per egg), raised blood cholesterol (and LDL). Out went the daily fried, scrambled, poached eggs that many Americans indulged in most mornings. (We replaced it with more breakfast cereals and other carbohydrate conveniences, then got enormously overweight.)A large Harvard epidemiologic study in 1999 called this observation into question. They tracked the fate of 117,000 thousand people and then compared the rate of heart attack, death, and other cardiovascular events among various people correlated to the "dose" of eggs they ate. Egg intake varied from none to 7 or more per week. Lo and behold, people who ate more eggs appeared to not suffer more events. This study, large and well-conducted by an internationally respected group of investigators, seem to reopen the gates for more egg consumption, though most Americans still consume eggs cautiously. Deeper down in this study, however, was another observation: People with diabetes who ate 1 egg per day had double the risk of heart attack. Because this study was observational, no specific conclusion as to why could be drawn. A new study conducted by a Brazilian group may shed some light. Healthy (non-diabetic) men were fed an emulsion of several eggs. Inclusion of plentiful yolks caused a dramatic slowing of fat clearance from the blood. Specifically, "chylomicron remnants" were abnormally persistent in the blood. Chylomicron remnants are potent causes of coronary plaque. (Chylomicron remnants can be measured fairly well by intermediate-density lipoprotein and VLDL by NMR, or IDL by VAP.)Diabetics are know to have substantial disorders of after-meal fat clearance, including an excess of chylomicron remnants. Could the Brazilian observation be the explanation for the increased event rate in diabetics in the Harvard study? Interesting to speculate. We continue to tell our patients that eating eggs in moderation is probably safe. After all, there are good things in eggs: the high protein in the egg white, lecithin in the yolk. It is the yolk's contents that are in question, not the white. Thus, you and I can eat all the egg whites (e.g., Egg Beaters) we want. It's the safety of yolks that are uncertain. The abnormal after-eating effect suggested by the Brazilians opens up some very interesting questions and confirms that we should still be cautious in our intake of egg yolks. One yolk per day is clearly too much. What is safe? The exisitng information would suggest that, if you have diabetes, pre-diabetes, or a postprandial disorder (IDL, VLDL), you should minimize your egg yolk use, perhaps no more than 3 or so per week, preferably not all at one but spaced out to avoid the after-eating effect.Others without postprandial disorders may safely eat more, perhaps 5 per week, but also not all at one but spaced out. Track Your Plaque Members: Be sure to read our upcoming Special Report on Postprandial Disorders. It contains lots of info on what this important pattern is all about. Postprandial disorders are largely unexplored territory that hold great promise for tools to inhibit coronary plaque growth and drop your heart scan score. The Brazilian study is just one of many future studies that are likely to be released in future about this very fascinating area.

Diabetes is Track Your Plaque's Kryptonite! 3. August 2006 William Davis (0) If there's one thing I truly fear from a heart scan score reduction/coronary plaque regression standpoint, it's diabetes. I saw a graphic illustration of this today. Roy came into the office after his 2nd heart scan. His first scan 14 months ago showed a score of 162. Roy started out weighing well over 300 lbs and with newly-diagnosed adult diabetes. Roy put extraordinary effort into his program. He lost nearly 70 lbs by walking; cutting processed carbohydrates, greasy foods, and slashing overall calories. His lipoproteins, disastrous in the beginning, were falling into line, though HDL was still lagging in the low 40s, as Roy remains around 60 lbs overweight, even after the initial 70 lb loss. Unfortunately, despite the huge loss in weight, Roy remains diabetic. On a drug called Actos, which enhances sensitivity to insulin, along with vitamin D to also enhance insulin response, his blood sugars remained in the overtly diabetic range. Roy's repeat heart scan showed a score of 482--a tripling of his original score. Obviously, major changes in Roy's program are going to be required to keep this rate of growth from continuing. But I tell Roy's story to illustrate the frightening power of diabetes to trigger coronary plaque growth. Like Kryptonite to Superman (remember George Reeves crumbling and falling to his knees when the bad guys got a hold of some?), diabetes is the one thing I fear greatly when it comes to reducing your heart scan score. As you see with Roy's case, diabetes can be responsible for explosive plaque growth, more than anything else I know. The best protection from diabetes is to never get it in the first place. (See my earlier Blog, "Diabetes is a choice you make".) << Vorherige Artikel Nächste Artikel >> Nächste Artikel12...108109110111112113114115116...123124Vorherige Artikel
The Track Your Plaque guide to getting grotesquely overweight 15. August 2006 William Davis (0) If you'd like to gain huge quantities of weight, here's a number of helpful tips:1) Follow the advice of food manufacturers and eat the products they label "healthy", or "heart healthy", or "part of a nutritious breakfast" etc., like Shredded Wheat cereal, pretzels ("a low-fat snack"!), low- or non-fat salad dressings. 2) Cut your morning calorie intake by skipping breakfast.3) Hang around with other heavy people. They will confirm that it's okay to be overweight. 4) Call walking your dog "exercise". 5) Get a sedentary desk job. Use your swivel desk chair to scoot about whenever possible, rather than getting up to do things. 6) Say "I've worked hard all week long. Weekends are for relaxing, not for physical activities. I deserve a rest."7) Eat foods without thinking about it: Eat chips while watching football, eat while on the phone, daydream over the sink.8) Eat to provide comfort when stressed.9) Eat foods that have sentimental value, whether or not they're good for you: Freshly-baked cakes that remind you of Mom, Pop Tarts that you used to carry in your lunchbox when you were a kid, hot dogs just like Dad would buy at the baseball stadium. 10) Cut back on sleep and generate insatiable starch cravings.11) Stack your shelves at home with great variety. That way, you'll always have something to suit your mood. 12) Say to your spouse: "It's none of your damn business what I eat! I'm a grown man/woman!" Prove it by over-indulging in obviously unhealthy foods. 13) Tell yourself that you're just too busy to pay attention to food choices. Just grab whatever you can out of a convenience store or vending machine. See, it's easy! And that just a start.Of course, I don't really want you to do any of these things. But if you see yourself in any of the above, and you're struggling with weight, you should seriously rethink your approach.
Your heart scan is just a "false positive" 15. August 2006 William Davis (0) I've seen this happen many times. Despite the great media exposure and the growing acceptance of my colleagues, heart scans still trigger wrong advice. I had another example in the office today.Henry got a CT heart scan in 2004. His score: 574. In his mid-50s, this placed him in the 90th percentile, with a heart attack risk of 4% per year. Henry was advised to see a cardiologist. The cardiologist advised Henry, "Oh, that's just a 'false positive'. It's not true. You don't have any heart disease. Sometimes calcium just accumulates on the outside of the arteries and gives you these misleading tests. I wish they'd stop doing them." He then proceeded to advise Henry that he needed a nuclear stress test every two years ($4000 each time, by the way). No attempt was made to question why his heart scan score was high, since the entire process was outright dismissed as nonsense. I'm still shocked when I hear this, despite having heard these inane responses for the past decade. Of course, Henry's heart scan was not a false positive, it was a completely true positive. I'm grateful that nothing bad happened to Henry through two years of negligence, though his heart scan score is likely around 970, given the expected, untreated rate of increase of 30%. The cardiologist did a grave disservice to Henry: He misled him due to his ignorance and lack of understanding. I wish Henry had asked the cardiologist whether he had read any of the thousands of studies now available validating CT heart scans. I doubt he's bothered to read more than the title. The cardiologist is lucky (as is Henry) that nothing bad happened in those two years.Do false positives occur as the cardiologist suggested? They do, but they're very rare. There's a rare phenomenon of "medial calcification" that occurs in smokers and others, but it is quite unusual. >99% of the time, coronary calcium means you have coronary plaque--even if the doctor is too poorly informed to recognize it.
What's better than a heart scan? 13. August 2006 William Davis (0) Do you know what's better than a heart scan?Two heart scans. No other method can provide better feedback on the results of your program. Say you've made efforts to correct high LDL; lost weight to raise HDL and reduce small LDL; added soluble fibers, nuts, and dramatically reduced wheat products; take fish oil, vitamin D, and follow a flavonoid-rich diet. Has it worked? After a year or so of your program, that's when another heart scan can give you invaluable feedback on whether it's been successful. I tell my patients that it's relatively easy to correct lipid and lipoprotein abnormalities. The difficult part is to know when it's good enough. Is your LDL of 67 mg/dl and HDL of 50 mg/dl good enough? Another heart scan score is the best way I know of to find out. Variation in plaque growth differs hugely from one person to another, even at equivalent lipoprotein values. Why? Lots of reasons. Humans are inconsistent day to day. Lipoproteins, being a snapshot in time and not a cumulative value, change somewhat from day to day. There's also the possibility of unmeasured, unrecognized factors that influence coronary plaque growth. We may not be smart enough to identify these hidden factors yet. But your heart scan score will incorporate the effects of these hidden factors.Ideally, we aim for zero growth in plaque (no change in score) or a reduction. But, particularly in the first year, 10% or less plaque growth is still a good result that predicts much reduced risk of heart attack. More than 20% per year and your program needs more work--or else you know what's ahead.
Lipids are snapshots in time; heart scans are cumulative 12. August 2006 William Davis (0) Let me paint a picture. It's fictional, though a very real portrait of how things truly happen in life. Michael is an unsuspecting 40-year old man. He hasn't undergone any testing: no heart scan, no lipids or lipoproteins. But we have x-ray vision, and we can see what's going on inside of him. (We can't, of course, but we're just pretending.) Average build, average lifestyle habits, nothing extraordinary about him. His lipids/lipoproteins at age 40:--LDL cholesterol 150 mg/dl--HDL cholesterol 38 mg/dl--Triglycerides 160 mg/dl--Small LDL 70% of all LDLAt age 40, with this panel, his heart scan score is 100. That's high for a 40-year old male. Fast forward 10 years. Michael is now 50 years old. Michael prides himself on the fact that, over the past 10 years, he's felt fine, hasn't gained a single pound, and remains as active at 50 as he did in 40. In other words, nothing has changed except that he's 10 years older. His lipids and lipoproteins:--LDL cholesterol 150 mg/dl--HDL cholesterol 38 mg/dl--Triglycerides 160 mg/dl--Small LDL 70% of all LDLSome of you might correctly point out that just simple aging can cause some deterioration in lipids and lipoproteins, but we're going to ignore these relatively modest issues for now.)Lipids and lipoproteins are, therefore, unchanged. Michael's heart scan score: 1380, or an approximate 30% annual increase in score. (Since Michael didn't know about his score, he took no corrective/preventive action.)My point: If we were to make our judgment about Michael's heart disease risk by looking at lipids or lipoproteins, they would'nt tell us where he stood with regards to heart disease risk. His lipids and lipoproteins were, in fact, the same at age 50 as they were at age 40. That's because measures of risk like this are snapshots in time. In contrast, the heart scan score reflects the cumulative effects of life and lipids/lipoproteins up until the day you got your scan. Which measure do you think is a better gauge of heart attack risk? I think the answer's obvious.
11. August 2006 William Davis (0) The recognition of the metabolic syndrome as a distinct collection of factors that raise heart disease risk has been a great step forward in helping us understand many of the causes behind heart disease. Curiously, there's not complete agreement on precisely how to define metabolic syndrome. The American Heart Association and the National Heart, Lung, and Blood Institute issued a concensus statement in 2005 that "defined" metabolic syndrome as anyone having any 3 of the 5 following signs:Waist size 40 inches or greater in men; 35 inches or greater in women Triglycerides 150 mg/dL or greater (or treatment for high triglycerides) HDL-C <40 mg/dL in men; <50 mg/dL in women (or treatment for reduced HDL-C) Blood Pressure >130 mmHg systolic; or >85 mmHg diastolic (or drug treatment for hypertension) Glucose (fasting) >100 mg/dL (or drug treatment for elevated glucose) Using this definition, it has become clear that meeting these criteria triple your risk of heart attack. But can you have the risk of metabolic syndrome even without meeting the criteria? What if your waste size (male) is, 36 inches, not the 40 inches required to meet that criterion; and your triglycerides are 160, but you meet none of the other requirements? In our experience, you certainly can carry the same risk. Why? The crude criteria developed for the primary practitioner tries to employ pedestrian, everyday measures. We see people every day who do not meet the criteria of the metabolic syndrome yet have hidden factors that still confer the same risk. This includes small LDL; a lack of healthy large HDL despite a normal total HDL; postprandial IDL; exercise-induced high blood pressure; and inflammation. These are all associated with the metabolic syndrome, too, but they are not part of the standard definition. I take issue in particular with the waist requirement. This one measure has, in fact, gotten lots of press lately. Some people have even claimed that waist size is the only requirement necessary to diagnose metabolic syndrome. Our experience is that features of the metabolic syndrome can occur at any waist size, though it increases in likelihood and severity the larger the waist size. I have seen hundreds of instances in which waist size was 32-38 inches in a male, far less than 35 inches in a female, yet small LDL is wildly out of control, IDL is sky high, and C-reactive protein is markedly increased. These people obtain substantial risk from these patterns, though they don't meet the standard definition. To me, having to meet the waist requirement for recogition of metabolic syndrome is like finally accepting that you have breast cancer when you feel the two-inch mass in your breast--it's too late. Recognize that the standard definition when you seen it is a crude tool meant for broad consumption. You and I can do far better.
What role DHEA? 9. August 2006 William Davis (2) DHEA, the adrenal gland hormone, has suffered its share of ups and downs over the years. Initially, DHEA was held up as the fountain of youth with hopes of turning back the clock 20 years. Such extravagant dreams have not held up. But DHEA can still be helpful for your program. All of us had oodles of DHEA in our bodies when we were in our 20s and 30s. Gradually diminishing levels usually reach nearly blood levels of around zero by age 70.

But if you're bursting with energy until you put your head on the pillow, you're more inclined to walk, bike, dance, play with the kids, dance, take Tai Chi, etc. Some downsides to DHEA: Some people experience aggression.
