What if your lipoproteins are perfect? 16. June 2006 William Davis (0) Sandy is a 56-year old woman--fit, slender, physically active, with no bad habits. A retired teacher, she has time to devote to her health. She bikes several days per week, mountain bikes, walks, and takes fitness classes. In short, she's the picture of perfect health. Her heart scan score was not terribly impressive: 41. However, at her age, this modest score placed her in the 77th percentile. This suggested a heart attack risk of around 2-3% per year.So we measured Sandy's lipoproteins. They were shockingly normal. In fact, Sandy is among the very rare person with absolutely no small LDL particles. All other patterns were just as favorable, including an HDL in the 80s. This may seem like good news, but I find it disturbing. People are often initially upset by seeing multiple abnormal lipoprotein patterns. But lipoprotein abnormalities are the tools that we use to gain control over coronary plaque. So what do we do when there are no abnormalities? There are several issues to consider:1) Your heart scan score reflects the sum total of your life up until that point. What if you were 20 lbs heavier 10 years earlier and your lipoproteins were abnormal during that period? Or you smoked until age 45 and quit? As helpful as they are, lipoproteins and related patterns are only a snapshot in time, unlike the heart scan score.2) You have a vitamin D deficiency. This is unusual as a sole cause of coronary plaque. Much more commonly, it is a co-conspirator. 3) The heart scan is wrong--highly unlikely. Heart scans are actually quite easy, straightforward tests. (The only time this tends to happen is when scoring that appears in the circumflex coronary artery is actually in the nearby mitral valve. This really occurs only when there's very minimal calcium in the valve.)4) There's a yet unidentified source of risk. Probably very rare but conceivable. For instance, there's an emerging sense that phopholipid patterns may prove to be coronary risks. One clinically available measure that we've not found very useful is phospholipase A2, known by the proprietary name "PLAC" test. (See http://www.plactest.com for more information from the manufacturer/distributor of the test.) But there's probably lots of others that may prove useful in future.How often does it happen that someone fails to show any identifiable source for their coronary plaque? I can count the number of instances on two fingers--very unusual. (Thank goodness!)Sandy's case is therefore quite unique. How should we approach her coronary plaque? In this unusual circumstance, lacking a cause, we tend to introduce therapies that may regress plaque independent of any measurable lipoprotein parameters. But that's a whole new conversation.
Fly to India for a bypass operation? 16. June 2006 William Davis (1) In the June 19, 2006 issue of People Magazine, there's an article called "The Doctor is in . . .INDIA". The report talks about how, with health care costs in the U.S. spiralling out of control, more and more Americans are leaving the country to have their procedure performed. They tell the story of Mr. Carlo Gislimberti of New Mexico and cite these numbers:Heart SurgeryCost in U.S.: $200,000Cost in India: $10,000 Mr. Gislimberti opted to have his coronary bypass operation in India for cost reasons. But the People magazine report left out one other option: The Track Your Plaque program: $39.00Do your part to save ballooning health care costs: Engage in a truly powerful program of heart disease prevention like the Track Your Plaque program. The cost difference is laughably huge. And you won't require a 12-inch chest incision. Follow conventional guidelines and guess what? You're going to have a heart attack. Follow the American Heart Association diet and you'll have heart disease. Cut to the chase. The only program that is able to detect, track, and control coronary plaque better than any other process I know of is this program.Note: I am not proposing that a heart disease prevention program like Track Your Plaque can replace a procedure like coronary bypass when a dangerous situation has developed. The Track Your Plaque program is designed to be implemented in the years before heart surgery is required. That's when you have the greatest control over your fate.
Surprise: Heart scan score reversal 14. June 2006 William Davis (0) Gene is a jovial, fun-loving railroad worker who didn't take anything too seriously--including his heart scan score of 767. This score placed Gene solidly in the 99th percentile (in the worst 1%). It came as no surprise to Gene. After all, his father died at age 36 of a heart attack and Gene's brother died at 60 of a heart attack. So Gene took life as it came and long ago decided not to fret about his fate.But Gene's wife prodded him and prodded him to get the heart scan. That's when I met him. Of course, Gene had been prescribed Lipitor by his doctor for a somewhat high LDL cholesterol. Our assessment uncovered several additional patterns including lipoprotein (a), small LDL, a pre-diabetic tendency, and a severe deficiency of vitamin D. At 224 lb and 5 ft 6 inches in height, I felt that Gene was at least 40 lbs overweight. One year later and with reasonable correction of all his patterns except weight loss and Gene's heart scan score was 590--a reduction of 23%! Gene was thrilled, as was I. But, frankly, I was also surprised. Dramatic regression of coronary plaque tends to not occur so readily as long as pre-diabetic patterns persist and weight is not controlled. The lesson: Often the only way to tell if you've achieved control or regression of coronary plaque is to have another heart scan. The tremendous variation in human responses never ceases to amaze me.
Call me when you're having chest pain 13. June 2006 William Davis (0) I met a patient, Anna, yesterday. She was quite frustrated and frightened. At age 50, Anna suffered a heart attack and received a stent to her left anterior descending coronary artery. What she found upsetting is that, because several members of her family had suffered heart attacks in their 40s (Dad--heart attack at age 45, paternal uncle--heart attack age 40, and even another uncle with heart attack in his late 20s), she had repeatedly asked her doctor whether she was okay. She received the usual array of false assurances: "You're feeling fine, right? Then don't worry about it." "Look. Your cholesterol is in the normal range. Even your cholesterol/HDL ratio is fine." "Women don't get heart disease until later in life."All proved absolutely false. As we talked, Anna exclaimed, "I think what I've been told all along is that we'll take you seriously when you finally have a heart attack!"She's exactly right. The vast majority of times, heart disease is discovered by accident, usually because of an "event" like heart attack. This is like changing the oil in your car when it finally breaks down--it's too late. CT heart scan, followed by lipoprotein testing and associated values, then correction of your specific causes. It's that simple.
Self-empowerment is coming! 11. June 2006 William Davis (0) I've discussed this before: The coming wave of self-empowerment in health. Health that is driven by you, not a hospital, not a doctor, not by procedures, but by information and access to tools that are powerful and effective. The seeds are being planted right now and won't take full root for many years or decades. But it's going to happen. I previously cited several broad trends that are examples of this emerging wave:--The nutritional supplement movement. Contrary to the media's ill-informed bashing, nutritional supplements are getting better: improved quality, better substantiation of when/how to use them, new agents that appear rapidly, since introduction is not slowed by the molasses of the FDA.--Medications moving to over-the-counter status. Health insurers are driving this one. OTC means not paid for by insurance. That also means access to you. --What I call "retail imaging", i.e. screening ultrasound, heart scans, full body scans, etc. that are available in most states without a doctor's order.--The Internet. The mind-boggling rapidity and depth of information available on the Internet today is fueling the self-empowerment movement by providing sophisticated information to health care consumers. Information here is uneven at present. But, as consumer sophistication increases and the system of checks and balances evolves, internet-driven information will be often superior to what you get from a doctor or other health professional.--High-deductible health insurance plans. If health care consumers bear more and more of the costs of health care, they will seize greater responsibility for early identification and prevention and minimize long-term costs.This trend does not mean treating your own infection, taking out your own gall bladder, repairing your own broken leg. It means that conventional routes of health delivery will recede into providing only catastrophic care. It means that you and your family will take a larger role in learning how to eat and exercise properly, use foods to maintain and promote health (the "designer food" and "nutraceutical" movement), take supplements that have real benefits, use medications for treatment of many everyday ailments. It also means seizing control of diseases that previously were only treated in hospitals, like coronary heart disease. This, of course, is where our program, Track Your Plaque, is an example of how you can have a powerful and effective role in your heart health. Track Your Plaque goes so far beyond the "eat low-fat, exercise, and know your numbers" media mantra that it's like comparing a brand-new Mercedes to a rusted, run-down '87 Ford Escort. There truly is no comparison. (Sorry if you're an Escort driver!) But you get the idea.
Another option for lipoprotein testing 9. June 2006 William Davis (0) For those of you who have been frustrated in trying to get your lipoprotein analysis performed, here's another option. The Life Extension Foundation at www.lef.org provides access to the VAP test, or Vertical Auto Profiler. This is the lipoprotein test run by the Atherotech company in Birmingham, Alabama. The name refers to the method used, a form of centrifugation, or high-speed spinning of your blood (plasma) to separate the various components by density. This is a fine technique that works well. Though our preferred method is NMR (www.Lipoprofile.com, Liposcience Inc.), the Atherotech VAP is a reasonable alternative. If you go through the Life Extension process, they will direct you to blood draw sites in your area. They charge $185 for Life Extension members, $247 for non-members. (Membership in Life Extension costs $75.) Drawback: No billing for health insurance reimbursement. A full description of the significance of lipoproteins can also be found in my article posted on-line at the www.lef.org website at http://www.lef.org/magazine/mag2006/may2006_report_heart_01.htm
Weight and lipoproteins 8. June 2006 William Davis (0) Tom, an accountant, came into the office eager to know what his 2nd heart scan score showed. A year ago, Tom's view of himself as a healthy, middle-aged man was shattered when he found out his heart scan score: 1236. Tom had severe coronary plaque with a heart attack risk of 25% per year (without intensive preventive action). In the way of lipoprotein abnormalities, he had several: low HDL, deficient large HDL, small LDL, high triglycerides, IDL (the after-eating inability to clear dietary fats), and a high blood sugar in the pre-diabetic range.

And the new slogan: "Get regressive."Interestingly, the new marketing campaign is based on relatively old data. They base this new claim on 3 studies:1) Cholesterol-Lowering Atherosclerosis Study (CLAS)--a 1987 CRP House of Cards 4. mayo 2009 William Davis (15) Lew has coronary plaque with a heart scan score of 393. At age 53, that's in the 90th percentile (higher score than 90% of men in his age group). On our search for causes of his coronary plaque, we identify low HDL of 41 mg/dl, high triglycerides of 202 mg/dl, small LDL (83% of total), calculated LDL of 133 mg/dl, and severe vitamin D deficiency with a starting blood level of 25-hydroxy vitamin D of 19 ng/ml.His c-reactive protein: 4.1 mg/dl--above the cut-off of 2.0 mg/dl that the pharmaceutical industry is targeting as a mandate for statin therapy, particularly given the JUPITER data. Lew instead eliminates wheat and other small LDL-provoking foods and, as a result, loses 28 lbs in 3 months; adds omega-3 fatty acids from fish oil; supplements vitamin D sufficient to increase his blood level to 70 ng/ml. Along with dramatic correction of his starting abnormalities, his c-reactive protein: 0.4 mg/dl--no statin drug.In my view, increased CRP is nothing more than a surrogate for the inflammatory phenomena that arise from high-carbohydrate diets, overweight, and small LDL. Correct those and CRP drops off a cliff. In fact, it is exceptionally rare for CRP to not drop to very low levels following this formula.I believe that CRP is one more item on the list of reasons--the house of cards--the pharmaceutical industry is building to persuade us to take more and more statin drugs. LDL not low enough? Take more statin. Diabetic with low cholesterol? Take a statin. Inflammation? Take a statin. Enough already. At-home blood tests 2. mayo 2009 William Davis (6) Our at-home blood tests are proving a hit. So far, vitamin D is the number one most popular test, no surprise. Second--to my surprise--is DHEA. I would have predicted it would have been thyroid testing. Our male and female hormone panels are also proving popular. I've personally been using the thyroid and vitamin D testing to monitor my levels. I increased my Armour thyroid based on a low free T3 value, while my vitamin D was perfect at 77 ng/ml on 8000 units vitamin D3 (cholecalciferol) per day. The process of performing the blood spots is straightforward. The finger pricks are virtually painless using the automatic spring-loaded finger stick devices: The number of blots to make depends on how many tests you'd like. Just a vitamin D test requires 2 blots. If 6 or more tests are ordered at a time, then all 12 blots should be made. (Two spring-loaded lancets are provided in each kit.) If you are interested in any of our at-home blood tests, go here. Our own Heart Hawk has posted an editorial on about blood spot testing on Health Central:Simple, affordable home blood testing is a real game-changer in the arena of informed, self-directed healthcare. For the first time broad access to home blood testing, on a scale similar to that enjoyed by persons who routinely test their blood sugar, is available to virtually everyone and it removes doctors as the gatekeepers of these tests. Even private insurance companies and Medicare are beginning to understand the potential for improving healthcare and decreasing costs and are slowly beginning to expand coverage of home blood testing much as they do for diabetics or persons taking anti-coagulants. "Help keep your family goiter free" 1. mayo 2009 William Davis (10) People ask, "If I need iodine, should I go back to iodized salt?"First of all, how did this notion of iodized salt originate?In 1924, J. Edgar Hoover was appointed head of the FBI, Marlon Brando and Doris Day were born, and Calvin Coolidge was elected President of the United States. Half of American households had a car, while 1 in 4 Americans were illiterate.In the 1920s, cities were a fraction of their current size and a third of the U.S. population, or 36 million people, lived in small rural communities.Goiters were also wildly prevalent in 1924. Up to a third of the population in some areas of the country, particularly the Midwest, suffered from goiters, thyroid glands that enlarged due to lack of iodine.Goiters were not only unsightly, but sometimes grotesque, causing a visible bulge in the front of the neck. Occasionally, they would grow so big that it compressed adjacent structures, like the trachea, and would have to be surgically removed. Goiters were commonly associated with thyroid dysfunction, especially low thyoid or hypothyroidism, that resulted in low IQ's in schoolchildren, debilitation in adults. Women of childbearing age delivered retarded children.So iodine deficiency in early 20th century America was a big problem. How to solve this enormous public health problem in a large nation without television, few radios, no internet, with a largely rural and often illiterate population?Thus was iodized salt born, a simple, technologically available solution that could be implemented on a large scale nationwide at low cost. The FDA chose this route in 1924, figuring that it was the best way to ensure that most Americans could obtain sufficient iodine through liberal use of iodized salt. Public health officials urged Americans to use salt. Morton's salt label proudly bore the slogan "Help keep your family goiter free!"It worked. Goiters largely became a thing of the past.How about today? The American Heart Association recommends limiting salt, recently announcing that they would like to limit intake to 1500 mg per day. The American Medical Association has been lobbying the FDA to set lower salt limit guidelines. The FDA has been clamping down on food manufacturers to reduce the quantity of salt in processed foods.Why limit salt? The concern is that there are segments of the population (not all) that are salt sensitive, particularly African Americans, people with certain genetic forms of high blood pressure, conditions that cause water retention, and any degree of heart or kidney failure. Salt in these peoplem, in fact, can be disastrous.So adding iodine to salt was the solution to epidemic goiter. And it worked.But salt is not a perfect solution, just one that served its purpose back in 1924. What we need is a 21st century solution.You will find that in the various iodine supplements at your health food store. My favorite is kelp--inexpensive, available, and a form that mimics the way Japanese people obtain iodine (though by eating seaweed, rather than with tablets).Image of kelp courtesy Wikipedia Thumb your nose at swine flu 29. abril 2009 William Davis (35) Judging from what we know about vitamin D, it is highly probable that it confers substantial protection from viral infections, including swine flu. Dr. John Cannell of the Vitamin D Council (www.vitamindcouncil.com) first connected the dots, identifying the possibility of an influence of vitamin D on incidence of flu.In 2006, Dr. Cannell reports noticing that the patients in his psychiatric ward in northern California were completely spared from the influenza epidemic of that year, while plenty of patients in adjacent wards were coming down with flu. Dr. Cannell proposed that the apparent immunity to flu in his patients may have been due to the modest dose of 2000 units vitamin D per day he had prescribed that the patients in other wards had not been given. (Since the hospital was run by the state of California, Dr. Cannell apparently had only so much leeway with vitamin D dosing.) While it’s not proof, it’s nonetheless a fascinating and compelling observation. A similar conclusion was reached in a recent analysis of the National Health and Nutrition Examination Survey demonstrating that the higher the vitamin D blood level, the less likely respiratory infections were. Personally, I used to suffer through 2 or 3 episodes of a runny nose, sore throat, hacking cough, fevers and feeling crumby every winter. Over the last 3 years since I’ve supplemented vitamin D, I haven’t been sick even once. The past two years I didn’t bother with the flu vaccine, since I suspected that my immunity had been heightened: no flu either winter. And so it has been with the majority of my patients. Since I began having patients supplement vitamin D to achieve normal blood levels (we aim for 60-70 ng/ml), viral and bacterial infections have become rare. New research is uncovering myriad new ways that vitamin D enhances natural immune responses to numerous infections, including tuberculosis, bacteria such as those causing periodontal disease and lung infections, and viruses like the influenza virus. Enhanced immunity against cancer is also an intensive area of research on vitamin D. Will vitamin D supplementation sufficient to achieve desirable blood levels confer sufficient immunity to swine flu should it come to your door? From what we know and what we’ve seen in the few years of vitamin D experience, I think it will in the majority. But I do believe that we should still heed public health warnings to avoid contact with others, minimize exposure to crowds, avoid travel to affected areas, etc. Will the real LDL please stand up? 26. abril 2009 William Davis (13) The results of the latest Heart Scan Blog poll are in.The question: How has your LDL been measured?
