The costs of doing drug business? 6. January 2011 William Davis (28) Here's a telling situation. Liz had been on prescription niacin, Niaspan, 1500 mg per day (3 x 500 mg tablets) for several years to treat her severe small LDL pattern and familial hypertriglyceridemia (triglycerides 500-1000 mg/dl). Because her health insurance had been paying for the "drug," she insisted on taking the prescription form. A change in insurance, however, meant that the Niaspan was no longer covered. Her pharmacy wanted to charge $227 per month. Liz came to the office in tears, worried that she was going to have to choke up $227 per month. I reminded her that, as I had told her several years ago, she could easily replace the Niaspan with over-the-counter Sloniacin or Enduracin. Both release niacin over approximately 6 hours, just like Niaspan. Here are the prices I've seen with Sloniacin, 100 tablets of 500 mg:Walgreens: $15.99 Walmart: $12.99Costco: $8.99So the most expensive source, Walgreens, would cost Liz just under $15.99 per month to take 1500 mg per day. $15.99 versus $227.00 per month for preparations that are highly similar. Hmmmmmm.I wonder what the $211.01 extra per month goes towards? Admittedly, Abbott Labs, the current company selling Niaspan (after Abbott acquired Kos), has invested in a few clinical trials, such as ARBITER-HALTS6. But does supporting research justify this much difference, a difference that amounts to $2532 over a year? If just 100,000 patients are prescribed Niaspan at this dose (a typical dose), this generates $253 million. Is the cost of developing and marketing a supplement-turned-drug that great? Is this justifiable? Is it any wonder that our health insurance premiums continue to balloon?I use Sloniacin and Enduracin almost exclusively.
Measurement 4. January 2011 William Davis (9) A crucial component of self-empowerment in healthcare is to be able to measure various health parameters. More and more measurement tools are entering the direct-to-consumer arena. Quantification of various phenomena is important in managing many aspects of health. Imagine a carpenter trying to build a house without the use of a tape measure, level, or other measuring tools. In health, as in building a house, measurement, adjustment, and correction are critical. Among the most helpful health measurement tools:Blood glucose meters--Blood glucose meters aren't just for diabetics. They are among the most powerful weight loss tools available. Blood pressure cuffs--There's no better way to assess blood pressure than to assess it under all the varied conditions of life: When you're tired, when you're excited, when you're upset, when you're happy, hungry, stomach full, morning, night. This is a lot better than the one isolated measure in the doctor's office.Digital thermometers--Your first a.m. oral temperature is a great way to assess thyroid status. We aim to maintain first a.m. oral temperature around 97.3 degrees F, the normal human temperature upon arising that reflects normal thyroid function. (No, Dr. Broda Barnes fans, axillary temperatures should NOT be used due to flagrant variation from right armpit to left armpit, modifying effects of clothing and ambient temperature, etc. Oral temperature tracks internal, "core," temperature fluctuations reliably, including circadian variation, far better than axillary temperatures.)Fingerstick blood tests--An incredible number of blood tests are now available just by performing a simple fingerstick in your kitchen or bathroom. You can get 25-hydroxy vitamin D, lipids, thyroid measures (TSH, free T3, free T4), hormones (DHEA, testosterone, estrogens). And the list is growing rapidly. Salivary tests are also growing in number for many of the same measures. A variation on fingerstick blood tests are devices like CardioChek that allow you to do a fingerstick, but also run the test on your own device at home. (The CardioChek device tests total cholesterol, triglycerides, and HDL.)Urine pH--You can dipstick your own urine to assess the relative acidity or alkalinity of your lifestyle. Acid pH (7 or below) suggests that diet is weighed too heavily in favor of animal products and grains. An alkaline pH (above 7) suggests plentiful vegetables and fruits, not counteracted by animal products and grains. There are many more, including the ZEO device to monitor sleep quality, RESPeRATE for reduction of blood pressure, HeartMath to manage stress and augment the parasympathatic (relaxation) response. We've come a long way compared to the health monitoring devices of just 25-30 years ago. Anyway, that's a partial list. Given the rapid advances in technology that allow such home tests, I anticipate a much longer list in the coming few years. For some perspective on how far these devices have come, here's a great graphic of an early sphygmomanometer, or blood pressure gauge. Courtesy Wellcome Library, London
I lost 37 lbs with a fingerstick 30. December 2010 William Davis (34) Jack needed to lose weight. At 5 ft 7 inches, he weighed in at 273 lbs, putting his BMI at a sobering 42.8. (A BMI of 30 or above is classified as "obese.") In addition to lipoprotein(a), Jack had an extravagant quantity of small LDL (the evil "partner" of lipoprotein(a)), high triglycerides, and blood sugars in the diabetic range. With a heart scan score of 1670, Jack had little room for compromises. Try as he might, Jack could simply not stick to the diet I urged him to follow. Three days, for instance, of avoiding wheat was promptly interrupted by his wife's tempting him with a nice BLT sandwich. This triggered his appetite, with diet spiraling downward in short order. So I taught Jack how to check his blood sugars using a fingerstick device, what I call the most important weight loss tool available. I asked Jack to check his pre-meal blood glucose and his one-hour after-meal blood glucose and not allow the after-meal blood glucose to rise any higher than the pre-meal. For example, if blood glucose pre-meal was 115 mg/dl, after-meal blood glucose should be no higher than 115 mg/dl.If any food or combination of foods increase blood glucose more than the pre-meal value, then eliminate the culprit food or reduce the portion size. For example, if dinner consists of baked salmon, asparagus, and mashed potatoes, and pre-meal blood glucose is 115 mg/dl, post-meal 155 mg/dl, reduce or eliminate the mashed potatoes. If slow-cooked, stone ground oatmeal causes blood glucose to increase from 115 mg/dl to 185 mg/dl (a typical response to oatmeal), then eliminate it.Having immediate feedback on the effects of various foods finally did it for Jack: It identified foods that were triggering excessive blood sugar rises (and thereby insulin) and foods that did not. What Jack did not do is limit or restrict calories. In fact, I asked him to eat portion sizes that left him comfortable. There was no need to reduce calories, push the plate away, etc. Just don't allow blood sugars to rise. Six months later, Jack came back 37 lbs lighter. And he got there without calorie-counting, without regulating portion sizes, without hunger.
The two kinds of small LDL 27. December 2010 William Davis (17) You won't find this in any publication nor description (at least ones that I've come across) about the ubiquitous small LDL particles. It's an observation I've made having obtained thousands of advanced lipoprotein panels of the sort that break lipoproteins down by size. I've discussed this issue previously here. But small LDL is so ubiquitous, not addressed by conventional strategies like statin drugs or fat restriction (it is made worse, in fact, by reducing fat in the diet), that it is worth keeping at the top of everyone's consciousness. (Because most of the lipoprotein analyses performed in my office are done via NMR, I will discuss in terms relevant to NMR. This does not necessarily mean that similar observations cannot be made with centrifugation, i.e, VAP from Atherotech, or gel electropheresis from Berkeley, Boston Heart Lab, Spectracell, and others). There are two basic varieties of small LDL particles:1) Genetically-programmed--e.g., via cholesteryl-ester transfer protein (CETP) activity2) Acquired--via carbohydrate consumptionIt means that people with acquired small LDL from carbohydrate consumption can reduce small LDL to zero with reduction of carbohydrates, especially the most small LDL-provoking foods of all: wheat, cornstarch, and sucrose. It also means that people who have small LDL for genetically-determined reasons can only minimize, not eliminate, small LDL. By NMR, we struggle to keep small LDL in the 300-600 nmol/L range when genetically-determined. (People typically start with 1400-3000 nmol/L small LDL particles prior to diet changes and other efforts.) We can only presumptively identify genetically-determined small LDL when all the appropriate efforts have been made, including reduction in weight to ideal, yet small LDL persists. Here is where we need better tools: when you've done everything possible, yet small LDL persists. While we break LDL particles (NOT LDL cholesterol, the crude and misleading way of viewing atherosclerosis causation) down by size, it's really about all the undesirable characteristics that accompany small size:--Distortion of Apo B conformation--i.e., the primary protein that directs LDL particle fate is distorted, making it less likely to be cleared by the liver but more likely to be taken up by inflammatory (macrophages) in the artery wall, creating plaque. It means that small LDL particles linger for a longer time than larger particles. --Small LDLs are more oxidation-prone. Oxidized LDL are more avidly taken up by inflammatory macrophages. --Small LDLs are more glycation-prone. --Small LDLs are more adherent to structural tissues, e.g., glycosaminoglycans, that reside in the artery wall. You and I cannot measure such phenomena, so we resort to distinguishing LDL particles by size. The drug industry believes it may have a solution to small LDL in the form of CETP-inhibiting drugs, like anacetrapib. In the way of nutritional solutions beyond carbohydrate reduction, weight loss/exercise, niacin, vitamin D normalization, and omega-3 fatty acid supplementation, there are exciting but very preliminary data surrounding the possibility that anthocyanins may inhibit CETP activity. Having toyed with this concept for the past 6 months, I remain uncertain how meaningful the effect truly is, but it is harmless, since we obtain anthocyanins from foods colored purple or purplish, such as blackberries, blueberries, cherries, red leaf lettuce, red cabbage, etc. I welcome any unique observations on this issue.
Don't forget the pumpkin in the wheat-free pumpkin bread 25. December 2010 William Davis (3) Ooops!Anyone who receives this blog via RSS feed may have received the Wheat-free pumpkin bread recipe in which I failed to list the pumpkin in the list of ingredients. Here's the recipe with all the ingredients.
Wheat-free pumpkin bread 25. December 2010 William Davis (5) Try this recipe for a wheat-free, gluten-free yet healthy "bread." Unlike many gluten-free foods that send blood sugar skyward, this will not. Ingredients:2 cups ground almond meal (Buy it from Trader Joe's--70% cheaper than other grocery stores.)1/2 cup ground flaxseed1/2 cup sour cream (full-fat, of course)15 oz canned pumpkin (Trader Joe's is bisphenol A-free)2 medium to large eggs1/2 cup chopped walnuts or pecans4 tablespoons butter, melted2 teaspoons baking powder2 teaspoons cinnamon1 teaspoon nutmeg or allspiceDash of saltChoice of non-nutritive sweetener (I used 3 teaspoons Trader Joe's stevia extract powder, the one mixed with lactose. Two tablespoons of Truvia, 1/2 teaspoon of the more concentrated stevia extract, or 1/2 cup Splenda are other choices. You can taste the mixed batter to gauge sweetness if in doubt.) Preheat oven to 350 degrees F. Grease baking pan (e.g., 10 x 6 inch). The pan should be big enough so that the mix will not be more than 2 inches deep, else it will require much longer to bake. (If you have only smaller pans, you will need to cook longer while the pan is covered with aluminum foil.) Mix all ingredients thoroughly in large bowl.

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 doubling from his reduced score. The message: Long-term consistency is key, even after you've achieved control over your score. Stick with your program--and don't get smug! Holidays are dangerous! 29. May 2006 William Davis (0) If you're on holiday from work today, make sure you're not on holiday from your health, too. Too often, people come back to the office telling me that the holidays simply got out of hand--cookouts, picnics, family gatherings, etc.--and they simply couldn't avoid overeating, overdrinking, sitting around--and gaining 3-5 lbs in a weekend. (Our record is 10 lbs in a weekend!)I don't want to harp on this issue and ruin your holiday, but I can't stress how important it is that you don't allow this to happen to you. Weight gained in a brief space of time has exceptionally destructive effects. Ever see the movie "Super Size Me"? It's an entertaining and well-done yet graphic portrayal of the damaging effects of rapid weight gain. Enjoy your time off. Relax, enjoy your family and friends--but continue to pay attention to choosing the right foods, don't overeat, take time out to do something (or several things) physical. It'll pay off hugely in the long run. More on carotid plaque... 29. May 2006 William Davis (1) Although not a perfect test, carotid ultrasound is an exceptionally easy and accessible test. Using high-frequency sound, clear images are available for most people. I say it's not perfect because the way it's done in 2006 makes it a non-quantitative test. It is a qualitative test. In other words, you may find out that there's a 30% blockage ("stenosis"), at the far end of the common carotid artery on the right side. Unfortunately, this gives you an isolated measure of diameter of the plaque compared to the artery. What it does not tell you is what the volume of the entire plaque is. That's a far more accurate measure (and one that is incorporated into your heart scan score, by the way).Nonetheless, carotid ultrasound is easy, very safe, and available in most hospitals and many clinics. One difficulty: most insurance companies will not allow you to go through a carotid ultrasound scan as a "screening" procedure, i.e., a test just to see if you have a carotid plaque. They will generally pay if you're having symptoms of a stroke or "mini-stroke" (transient ischemic attack, or "TIA"), have an abnormal sound in your carotid ultrasound detected by your doctor (a carotid "bruit"), or some other unusual indications. Sometimes, a resourceful physician will muster up a diagnosis based on something in your history (e.g., left arm numbness, a common and often benign complaint that can also signal stroke). Another option are the mobile scanners or some hospital services that offer carotid screening, usually for a very modest price. Drawback: Sporadic availability, difficulty in obtaining serial scans, and imprecise reporting since it's viewed as a screening test. But it's better than nothing. My hope is that, as screening services using safe imaging techniques like ultrasound propagate and increase in direct availability to the public, you'll be able to circumvent the obstacles imposed by your insurance company and even, sometimes, your doctor. But try your doctor first. Carotid plaque can be shrunk 28. May 2006 William Davis (1) Rose, a 64-year old woman, just had a 70% carotid blockage identified by a screening ultrasound. When the result was given to her doctor, he prescribed Lipitor and told Rose that an ultrasound would be required every year. She would need carotid surgery, an "endarterectomy", if the blockage worsened. "Can't I reduce the amount of blockage I have?" asked Rose. "No. Once you've got it, it doesn't get any better."Is this true? Once you've got carotid plaque, you can only expect it to get worse and it can't be reduced?This is absolutely not true. In fact, compared to coronary plaque, carotid plaque is easier to reduce! Of course, the Track Your Plaque program is designed to help you control or reduce coronary plaque. But, in our experience, people who have both coronary and carotid plaque will show far greater and faster reduction of carotid plaque. Dramatic reductions are sometimes seen. I've personally seen 50-70% blockages reduced to <30% on many occasions. The requirements to achieve reduction of carotid plaque are very similar to the approach we use to reduce coronary plaque. One difference is that hypertension may play a more important role with carotid plaque and needs to be reduced confidently to the normal range before carotid plaque is controlled.I find it shocking that the attitude like the one provided by this physician continue to prevail. Unlike coronary plaque, which has a relatively small body of scientific literature documenting how it can be reduced, carotid plaque actually enjoys a substantial clinical literature. Part of the reason is that the carotids are more easily imaged using ultrasound. (Heart structures can be seen with ultrasound, but not the coronary arteries.)Numerous agents have been shown to contribute to reduction of carotid plaque: statin drugs, niacin, fish oil, the anti-diabetic "TZD" drugs (Actos, Avandia), several anti-hypertensive drugs, vitamin E, pomegranate juice, and several others. It outrages me to hear stories like this. Rose is not the only one. Don't accept the flip dismissals or the over-enthusiastic referral for carotid procedures. Insist on a conversation about plaque regression. Note: Although I am a vigorous advocate of atherosclerotic plaque regression, this does not mean that if you have a severe (70% blockage or greater), or if there are symptoms from your carotid disease, that you should engage in a program of reversal. You must always take the advice of your doctor if your safety is in question. Vitamin D--A coronary risk factor 27. May 2006 William Davis (1) Look up "coronary risk factors" in any text and you'll find high cholesterol, smoking, diabetes, and high blood pressure listed. You won't find deficiency of vitamin D listed. Ask 99% of physicians if a deficiency of vitamin D is a coronary risk factor and you'll get rolling eyes and a sigh.Yet, in the Track Your Plaque experience, vitamin D is emerging as a very important factor in coronary plaque development. We have observed that there are a substantial number of people whose lipids and lipoproteins are not abnormal enough to fully explain their heart scan score. In other words, there seems to be something else necessary to satisfactorily explain the magnitude of coronary plaque. I believe that severe vitamin D deficiency is at least one of the most important factors. We've seen many people with blood levels of vitamin in the range of severe deficiency (<20 ng/ml of 25-OH-Vitamin D3) yet bland lipids and lipoproteins. Correcting vitamin D blood levels to 50 ng/ml also seems to be among the required factors in stopping coronary plaque growth, or stopping your heart scan score from increasing.Keep your eye on this extremely important and exciting issue. Sadly, it won't be propelled into the media like the conversation about cholesterol or high-tech procedures, since no company stands to profit from it. But you and I don't have to play that game. Cholesterol is dead! 26. May 2006 William Davis (0) I saw a patient in the office yesterday. He came to me for an opinion regarding his high heart scan score of 525, putting him in the 90th percentile (5% annual risk of heart attack). His doctor had been puzzled because his LDL cholesterols had ranged from 110 to 131 mg--actually below average. (The average LDL for the U.S. is 132 mg.) Likewise, HDL was a favorable 63 mg. Lipoprotein analysis told the story loud and clear. His LDL particle number, a far more precise measure of LDL, was 2448 nmol/l. This means that his true LDL was more like 240-250 mg! (You can get a sense for what the true LDL is from LDL particle number by dropping the last digit: 2448 becomes 244.) Conventional LDL was therefore inaccurate by over 100 mg.He also had a severe small LDL particle pattern. The cause of his coronary plaque was a large excess of small LDL particles. LDL cholesterol (and total cholesterol, likewise) didn't even hint at this pattern. Nor did his favorable HDL. Think of LDL particle number as an actual count of LDL particles per volume, e.g., number of particles per cc of blood. This makes it easier to conceptualize. LDL particle number is the measure you get when you have an NMR lipoprotein profile, our preferred method of lipoprotein testing. If this is unavailable to you, apoprotein B is a reasonable second choice, though not as accurate in my view. More info on NMR is available at their website, www.lipoprofile.com. How to make a $1 million in cardiology 26. May 2006 William Davis (0) Want to make a $1,000,000 as a cardiologist in the next year? It's easy. All you have to do is:1) Perform heart catheterizations or other procedures on anybody you can, even if it's not necessary. Perform them even if the patient has no symptoms and the stress test is normal. 2) Perform heart catheterizations if the patient is too timid or ill-informed to object. 3) Insert coronary stents in blockages, even when they're minor and it's not necessary. 4) Turn every heart procedure into a revenue-producing stream by looking for other profit opportunties, such as minor kidney artery blockages. 5) Heart disease is frightening. Scare the heck out of patients by exagerrating the dangers so they'll go through testing and procedures gratefully. Sound absurd? Well, it would be if these weren't all true.These are real examples, as awful as it sounds. I've witnessed all these behaviors. Not just occasionally, but with regularity. Just today, I encountered a colleague who performs heart catheterizations routinely (up to several per day) when any symptom is present and the stress test is entirely normal. This is grossly inappropriate.Your protection is being better-informed and avoid being sucked into the vast and frightening cardiovascular machine of revenue-yielding procedures. Part of your protection is to get a CT heart scan, then engage in a program of heart disease prevention. Doctor, do I have lipoprotein (a)? 25. May 2006 William Davis (0) I met Joyce today for a 2nd opinion. She told me about this conversation she'd had with her cardiologist:"Doctor, do you think I could have lipoprotein (a)? I read about how it can cause heart attacks even when cholesterol is controlled.""What does it matter? Even if you have it, there's nothing we can do about it. There's no treatment for it."Joyce was understandably groping for some means to prevent her coronary disease from causing more danger. At 56, she'd already survived a heart attack that resulted in two stents to her left anterior descending. Around 9 months later, she received a 3rd stent to another artery. Her doctor had put her on Pravachol and said that was enough. "We know that cholesterol causes heart disease and the Pravachol reduces it. Why do we need to know anything more?"So Joyce came to me for another view. I explained to her that there are, in fact, several ways to deal with lipoprotein(a). It is, without a doubt, among the more difficult patterns to manage--but not impossible. In fact, we have a growing list of participants in the Track Your Plaque program who have stopped or reduced their heart scan scores. I continue to be horrified at the level of ignorance that prevails among my colleagues, the cardiologists, and the primary care community. If your doctor gives you advice like this, get a new doctor. << Older posts Newer posts >> Newer posts12...114115116117118119120121122123124Older posts

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 doubling from his reduced score. The message: Long-term consistency is key, even after you've achieved control over your score. Stick with your program--and don't get smug!
Holidays are dangerous! 29. May 2006 William Davis (0) If you're on holiday from work today, make sure you're not on holiday from your health, too. Too often, people come back to the office telling me that the holidays simply got out of hand--cookouts, picnics, family gatherings, etc.--and they simply couldn't avoid overeating, overdrinking, sitting around--and gaining 3-5 lbs in a weekend. (Our record is 10 lbs in a weekend!)I don't want to harp on this issue and ruin your holiday, but I can't stress how important it is that you don't allow this to happen to you. Weight gained in a brief space of time has exceptionally destructive effects. Ever see the movie "Super Size Me"? It's an entertaining and well-done yet graphic portrayal of the damaging effects of rapid weight gain. Enjoy your time off. Relax, enjoy your family and friends--but continue to pay attention to choosing the right foods, don't overeat, take time out to do something (or several things) physical. It'll pay off hugely in the long run.
More on carotid plaque... 29. May 2006 William Davis (1) Although not a perfect test, carotid ultrasound is an exceptionally easy and accessible test. Using high-frequency sound, clear images are available for most people. I say it's not perfect because the way it's done in 2006 makes it a non-quantitative test. It is a qualitative test. In other words, you may find out that there's a 30% blockage ("stenosis"), at the far end of the common carotid artery on the right side. Unfortunately, this gives you an isolated measure of diameter of the plaque compared to the artery. What it does not tell you is what the volume of the entire plaque is. That's a far more accurate measure (and one that is incorporated into your heart scan score, by the way).Nonetheless, carotid ultrasound is easy, very safe, and available in most hospitals and many clinics. One difficulty: most insurance companies will not allow you to go through a carotid ultrasound scan as a "screening" procedure, i.e., a test just to see if you have a carotid plaque. They will generally pay if you're having symptoms of a stroke or "mini-stroke" (transient ischemic attack, or "TIA"), have an abnormal sound in your carotid ultrasound detected by your doctor (a carotid "bruit"), or some other unusual indications. Sometimes, a resourceful physician will muster up a diagnosis based on something in your history (e.g., left arm numbness, a common and often benign complaint that can also signal stroke). Another option are the mobile scanners or some hospital services that offer carotid screening, usually for a very modest price. Drawback: Sporadic availability, difficulty in obtaining serial scans, and imprecise reporting since it's viewed as a screening test. But it's better than nothing. My hope is that, as screening services using safe imaging techniques like ultrasound propagate and increase in direct availability to the public, you'll be able to circumvent the obstacles imposed by your insurance company and even, sometimes, your doctor. But try your doctor first.
Carotid plaque can be shrunk 28. May 2006 William Davis (1) Rose, a 64-year old woman, just had a 70% carotid blockage identified by a screening ultrasound. When the result was given to her doctor, he prescribed Lipitor and told Rose that an ultrasound would be required every year. She would need carotid surgery, an "endarterectomy", if the blockage worsened. "Can't I reduce the amount of blockage I have?" asked Rose. "No. Once you've got it, it doesn't get any better."Is this true? Once you've got carotid plaque, you can only expect it to get worse and it can't be reduced?This is absolutely not true. In fact, compared to coronary plaque, carotid plaque is easier to reduce! Of course, the Track Your Plaque program is designed to help you control or reduce coronary plaque. But, in our experience, people who have both coronary and carotid plaque will show far greater and faster reduction of carotid plaque. Dramatic reductions are sometimes seen. I've personally seen 50-70% blockages reduced to <30% on many occasions. The requirements to achieve reduction of carotid plaque are very similar to the approach we use to reduce coronary plaque. One difference is that hypertension may play a more important role with carotid plaque and needs to be reduced confidently to the normal range before carotid plaque is controlled.I find it shocking that the attitude like the one provided by this physician continue to prevail. Unlike coronary plaque, which has a relatively small body of scientific literature documenting how it can be reduced, carotid plaque actually enjoys a substantial clinical literature. Part of the reason is that the carotids are more easily imaged using ultrasound. (Heart structures can be seen with ultrasound, but not the coronary arteries.)Numerous agents have been shown to contribute to reduction of carotid plaque: statin drugs, niacin, fish oil, the anti-diabetic "TZD" drugs (Actos, Avandia), several anti-hypertensive drugs, vitamin E, pomegranate juice, and several others. It outrages me to hear stories like this. Rose is not the only one. Don't accept the flip dismissals or the over-enthusiastic referral for carotid procedures. Insist on a conversation about plaque regression. Note: Although I am a vigorous advocate of atherosclerotic plaque regression, this does not mean that if you have a severe (70% blockage or greater), or if there are symptoms from your carotid disease, that you should engage in a program of reversal. You must always take the advice of your doctor if your safety is in question.
Vitamin D--A coronary risk factor 27. May 2006 William Davis (1) Look up "coronary risk factors" in any text and you'll find high cholesterol, smoking, diabetes, and high blood pressure listed. You won't find deficiency of vitamin D listed. Ask 99% of physicians if a deficiency of vitamin D is a coronary risk factor and you'll get rolling eyes and a sigh.Yet, in the Track Your Plaque experience, vitamin D is emerging as a very important factor in coronary plaque development. We have observed that there are a substantial number of people whose lipids and lipoproteins are not abnormal enough to fully explain their heart scan score. In other words, there seems to be something else necessary to satisfactorily explain the magnitude of coronary plaque. I believe that severe vitamin D deficiency is at least one of the most important factors. We've seen many people with blood levels of vitamin in the range of severe deficiency (<20 ng/ml of 25-OH-Vitamin D3) yet bland lipids and lipoproteins. Correcting vitamin D blood levels to 50 ng/ml also seems to be among the required factors in stopping coronary plaque growth, or stopping your heart scan score from increasing.Keep your eye on this extremely important and exciting issue. Sadly, it won't be propelled into the media like the conversation about cholesterol or high-tech procedures, since no company stands to profit from it. But you and I don't have to play that game.
Cholesterol is dead! 26. May 2006 William Davis (0) I saw a patient in the office yesterday. He came to me for an opinion regarding his high heart scan score of 525, putting him in the 90th percentile (5% annual risk of heart attack). His doctor had been puzzled because his LDL cholesterols had ranged from 110 to 131 mg--actually below average. (The average LDL for the U.S. is 132 mg.) Likewise, HDL was a favorable 63 mg. Lipoprotein analysis told the story loud and clear. His LDL particle number, a far more precise measure of LDL, was 2448 nmol/l. This means that his true LDL was more like 240-250 mg! (You can get a sense for what the true LDL is from LDL particle number by dropping the last digit: 2448 becomes 244.) Conventional LDL was therefore inaccurate by over 100 mg.He also had a severe small LDL particle pattern. The cause of his coronary plaque was a large excess of small LDL particles. LDL cholesterol (and total cholesterol, likewise) didn't even hint at this pattern. Nor did his favorable HDL. Think of LDL particle number as an actual count of LDL particles per volume, e.g., number of particles per cc of blood. This makes it easier to conceptualize. LDL particle number is the measure you get when you have an NMR lipoprotein profile, our preferred method of lipoprotein testing. If this is unavailable to you, apoprotein B is a reasonable second choice, though not as accurate in my view. More info on NMR is available at their website, www.lipoprofile.com.
How to make a $1 million in cardiology 26. May 2006 William Davis (0) Want to make a $1,000,000 as a cardiologist in the next year? It's easy. All you have to do is:1) Perform heart catheterizations or other procedures on anybody you can, even if it's not necessary. Perform them even if the patient has no symptoms and the stress test is normal. 2) Perform heart catheterizations if the patient is too timid or ill-informed to object. 3) Insert coronary stents in blockages, even when they're minor and it's not necessary. 4) Turn every heart procedure into a revenue-producing stream by looking for other profit opportunties, such as minor kidney artery blockages. 5) Heart disease is frightening. Scare the heck out of patients by exagerrating the dangers so they'll go through testing and procedures gratefully. Sound absurd? Well, it would be if these weren't all true.These are real examples, as awful as it sounds. I've witnessed all these behaviors. Not just occasionally, but with regularity. Just today, I encountered a colleague who performs heart catheterizations routinely (up to several per day) when any symptom is present and the stress test is entirely normal. This is grossly inappropriate.Your protection is being better-informed and avoid being sucked into the vast and frightening cardiovascular machine of revenue-yielding procedures. Part of your protection is to get a CT heart scan, then engage in a program of heart disease prevention.
Doctor, do I have lipoprotein (a)? 25. May 2006 William Davis (0) I met Joyce today for a 2nd opinion. She told me about this conversation she'd had with her cardiologist:"Doctor, do you think I could have lipoprotein (a)? I read about how it can cause heart attacks even when cholesterol is controlled.""What does it matter? Even if you have it, there's nothing we can do about it. There's no treatment for it."Joyce was understandably groping for some means to prevent her coronary disease from causing more danger. At 56, she'd already survived a heart attack that resulted in two stents to her left anterior descending. Around 9 months later, she received a 3rd stent to another artery. Her doctor had put her on Pravachol and said that was enough. "We know that cholesterol causes heart disease and the Pravachol reduces it. Why do we need to know anything more?"So Joyce came to me for another view. I explained to her that there are, in fact, several ways to deal with lipoprotein(a). It is, without a doubt, among the more difficult patterns to manage--but not impossible. In fact, we have a growing list of participants in the Track Your Plaque program who have stopped or reduced their heart scan scores. I continue to be horrified at the level of ignorance that prevails among my colleagues, the cardiologists, and the primary care community. If your doctor gives you advice like this, get a new doctor.
