When it's a hormone.

That's the stand that several researchers in vitamin D have taken and I think they're right. Dr. John Cannell has made a fuss over this in his www.vitamindcouncil.com website.

Structurally, vitamin D is most closely related to testosterone, estrogen, and cortisol. You wouldn't call testosterone vitamin T, would you?

Vitamins are also meant to be obtained from food. Yes, vitamin D is in milk but only because humans are required to put it there to prevent childhood rickets. Otherwise, the only substantial food source o All posts by william-davis

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: $12.99
Costco: $8.99

So 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.

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) activity
2) Acquired--via carbohydrate consumption

It 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 flaxseed
1/2 cup sour cream (full-fat, of course)
15 oz canned pumpkin (Trader Joe's is bisphenol A-free)
2 medium to large eggs
1/2 cup chopped walnuts or pecans
4 tablespoons butter, melted
2 teaspoons baking powder
2 teaspoons cinnamon
1 teaspoon nutmeg or allspice
Dash of salt
Choice 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. Pour mix into greased baking pan.

Cover with aluminum foil and bake for 30 minutes. Remove foil and bake for additional 30 minutes or until inserted toothpick or knife comes out dry.

Serve with cream cheese or as is.

(I'd have some pictures, but the kids and I ate it up before I thought to take any photographs.)

Vitamin D: Deficiency vs optimum level

19. December 2010 William Davis (20)

Dr. James Dowd of the Vitamin D Cure posted his insightful comments regarding the Institute of Medicine's inane evaluation of vitamin D.

Dr. Dowd hits a bullseye with this remark:

The IOM is focusing on deficiency when it should be focusing on optimal health values for vitamin D. The scientific community continues to argue about the lower limit of normal when we now have definitive pathologic data showing that an optimal vitamin D level is at or above 30 ng/mL. Moreover, if no credible toxicity has been reported for vitamin D levels below 200 ng/mL, why are we obsessing over whether our vitamin D level should be 20 ng/mL or 30 ng/mL?

Yes, indeed. Have no doubts: Vitamin D deficiency is among the greatest public health problems of our age; correction of vitamin D (using the human form of vitamin D, i.e., D3 or cholecalciferol, not the invertebrate or plant form, D2 or ergocalciferol) is among the most powerful health solutions.

I have seen everything from relief from winter "blues," to reversal of arthritis, to stopping the progression of aortic valve disease, to partial reversal of dementia by achieving 25-hydroxy vitamin D levels of 50 ng/ml or greater. (I aim for 60-70 ng/ml.)

The IOM's definition of vitamin D adequacy rests on what level of 25-hydroxy vitamin D reverses hyperparathyroidism (high PTH levels) and rickets. Surely there is more to health than that.

Dr. Dowd and vocal vitamin D advocate, Dr. John Cannell, continue to champion the vitamin D cause that, like many health issues, conradicts the "wisdom" of official organizations like the IOM.

Large LDL counts, too

15. December 2010 William Davis (0)

Chad is a 43-year old father of five kids.

Earlier this year, he developed chest pain that got worse and worse. He ended up with a total of five stents in all three coronary arteries. After a devastating experience with Lipitor that resulted from a ruptured tendon, he came to me for an option.

Slow Burn works

14. December 2010 William Davis (55)

I have been impressed with the results I've been obtaining with Fred Hahn's Slow Burn strength training technique.

Because I have limited time to hang around the gym, any technique that provides outsized results in a limited amount of time, I have to admit, appeals to me. In past, I'd be lucky to squeeze in one or two strength training sessions per week, devoting the rest of the time to biking outdoors, biking on a sedentary bike (while playing XBox), jogging, or doing strenuous yard work like digging trenches and planting shrubs.

Over the years, I've gradually lost muscle, since the strength training effort suffered with my time limitations.

So Fred's time-efficient Slow Burn idea struck a chord. Having now done it with some regularity, usually 1-2 times per week since mid-September, I have gradually added back visible muscle. My Slow Burn workouts, involving 8-10 different movements, seem to have restored the muscle I've lost, with a very modest time effort.

It took a little getting used to. After Fred showed me how to do the movements--slow motion movement in both the "positive" and "negative" directions, with smooth, non-jerking transitions, one set per muscle group, each taken to muscle exhaustion--it left me unusually tired and sore the next day. This surprised me, given the limited time involved. Breathing is also very important; the usual exhale-during-the-positive, inhale-during-the-negative pattern is replaced by breathing freely during the entire set. I didn't get this at first and ended up with headaches that got worse with each set. Breathing freely relieved me from the effect.

I have strength trained since I was around 15 years old. Back in the early 1970s, I had about 2000 lbs of barbells and dumbbells in my garage in New Jersey, while also driving back and forth to the Morristown, NJ, YMCA to train with friends. The Slow Burn movements forced me to break habits established over nearly 40 years of conventional strength training.

I've also played around with mixing conventional movements with Slow Burn movements to keep it fresh. This also seems to work.

If you're interested in giving it a try, here's an animation that demonstrates what Slow Burn movements look like. Fred has also produced an excellent 3-DVD set of videos that more fully describe the practice.

Do your part to save on healthcare costs

13. December 2010 William Davis (37)

While many of the factors that drive the relentless increase in health care costs are beyond individual control, you are still able to exert personal influence over costs. Just as in political elections, your one vote alone may not count; it's the collective effort of many people who share similar opinions that results in real change.

I just got the new monthly premium for my high-deductible health insurance: Up $300 per month, putting my family's total premium over $2000 per month---for four healthy people. (My son fractured his wrist playing high school hockey earlier this year; that may explain at least some of the increase.)

I'm going to shop around for a better deal. However, shopping is likely to only stall the process. It will not address the systemic problems with healthcare that continue to drive premiums up and up and up.

So what can you do to help keep costs down? Here are a few thoughts:

Never accept a prescription for fish oil, i.e., Lovaza. Just buy far less costly over-the-counter fish oil. I treat complex hyperlipidemias, including familial hypertriglyceridemia, ever day. I NEVER use prescription fish oil. A typical 4 capsule per day Lovaza prescription adds around $280 to $520 per month to overall health costs (though your direct out-of-pocket costs may be less, since you shove the costs onto others in your plan).

Never accept a prescription for vitamin D. Prescription vitamin D is the mushroom or invertebrate form anyway. Just buy the human (cholecalciferol, D3) form from your health food store or "big box" store. They yield consistent increases in 25-hydroxy vitamin D levels, superior to the prescription form. And they're wonderfully inexpensive.

Eliminate wheat from your diet. If there is a dietary strategy that yields unexpected and outsized benefits across a wide spectrum of health, it's elimination of this thing we're sold called "wheat," you know, the genetically-transformed, high-yield dwarf mutant that now represents 99% of all wheat sold. Blood sugar drops, pre-diabetics become non-prediabetics, diabetics reduce need for medication or become non-diabetic, cholesterol values plummet, arthritis improves, acid reflux and irritable bowel symptoms improve or disappear, just to mention a few. Wheat elimination alone, I believe, would result in incalculable savings in both healthcare costs and lives saved.

Be sure to obtain iodine. In the fuss to cut salt use, everyone forgot about iodine. Lack of iodine leads to thyroid disease, usually hypothyroidism, that, in turn, causes cholesterol values to increase, weight to increase, and heart disease risk to double, triple, or quadruple. Iodine supplementation is easy and wonderfully inexpensive.

Over time, I hope that all of us can help develop the effort to self-direct more and more of our own health. Our Track Your Plaque program has shown me that, not only can people take the initiative to direct aspects of their own health, they can do it better than 99% of doctors.

I'm sure there are many, many other ways to help reduce costs. Any suggestions?

Kitchen sink approach for Lp(a)

29. August 2008 William Davis (12)

Lipoprotein(a), Lp(a), can be a tough nut to crack.

Having struggled and wrestled with this genetic pattern for the last 12 years or so in hundreds of patients, I have gained great respect for this difficult to control pattern.

I regard lipoprotein(a) as the number one most aggressive cause for heart disease and coronary plaque known. It can account for heart attacks in men in their 40s, women in their 50s. It can cause heart disease and heart attacks in even the ultra-fit like marathon runners. It accounts for both excessive coronary risk and misleading cholesterol values in slender, healthy-appearing people.

Niacin is the number one treatment choice for Lp(a), followed by testosterone for men, estrogens (preferably human, not horse or other non-human mammal) for women. I then often resort to DHEA, along with adjunctive nutritional agents like raw almonds, ground flaxseed, and others.

Our most recent addition to the Lp(a) treatment list is high-dose fish oil, which appears to exert a significant effect in about 40% of people with Lp(a).

Even with this multi-agent approach, not everybody gains control over Lp(a).

That makes me wonder if someone has Lp(a) at a substantial level of, say, 200 nmol/L or 70 mg/dl (values can differ tremendously, depending on the method of measurement), should we throw everything but the kitchen sink at Lp(a) from the start? Right now, by adding an agent one at a time, it often takes two years to gain control over Lp(a) (if we are going to get it at all).

While many people might find this unpalatable and overwhelming from the starting gate of their program, I do believe it may be a strategy we should consider adopting for full and more immediate plaque control in the Track Your Plaque program. Something to chew on.

Clearly, we need better answers for Lp(a). A "kitchen sink," full-frontal assault might be a way to gain faster control, though not necessarily a superior approach with regards to efficacy and potency.

There are a number of unique, potentially effective therapies for Lp(a) that are worth examining. Given the difficulty of performing clinical trials with non-drug agents (largely a lack of financial support, since nobody gets a financial return with non-patent-protectable agents), I am anxious to put these potential treatments to a test in the Track Your Plaque program Virtual Clinical Trail (VCT). The VCT gives us a quick and relatively easy method to test various potential treatments, with feedback generated in months, rather than years.

Any suggestions on promising agents to test? Of course, they must be widely available nutritional agents, not drugs.

Making Dr. Friedewald an honest man

28. August 2008 William Davis (3)

Colleen started with the usual discrepancy between conventional calculated LDL cholesterol of 121 mg/dl and the far more accurate LDL particle number (NMR) of 1927 nmol/L.

Those of you following this conversation or our many conversations on the Track Your Plaque Forum know that a useful and highly reliable rule-of-thumb for converting NMR LDL particle number to LDL is to drop the last digit: 1927 nmol/L becomes 192 mg/dl. (This is, admitttedly, arrived at empirically, not by design. However, it has held up through thousands of NMR analyses and plays out reasonably when you compare distributions of Friedewald LDL and LDL particle number on a population basis.)

In other words, by this simple manipulation, Colleen's Friedewald calculated LDL is off by 58%. This is very common, a phenomenon I witness several times every day.

By LDL particle size, 75% of all Colleen's LDL particle were abnormally small (small LDL particle number 1440 nmol/L). This is a moderately severe small LDL tendency.

So we took all the steps for reduction of small LDL/LDL, including elimination of wheat and cornstarch, exercise, weight loss (which happens inevitably when wheat and cornstarch are eliminated), fish oil, vitamin D, etc.

Another NMR lipoprotein panel showed an LDL particle number of 882 nmol/L and a Friedewald calculated LDL of 87 mg/dl. Using our rule-of-thumb, LDL by particle number is virtually the same as the calculated LDL. This time, small LDL numbered only 237 nmol/L, or 26.8% of the total, a marked reduction.

Isn't that interesting? As small LDL is corrected, the crude Friedwald calculated LDL approximates the more accurate LDL particle number.

It assumes that accuracy of the Friedewald calculation may be more likely to occur as LDL size approaches normal. However, when LDL size is abnormally small--a condition shared by at least 70% of people with coronary heart disease--then the Friedewald LDL becomes increasingly inaccurate.

The opposite can also happen: When all or nearly all LDL particles are large, Friedewald calculated LDL can markedly overestimate LDL particle number. Yesterday, for instance, a patient had a Friedewald calculated LDL of 183 mg/dl, but an NMR particle number of 1110 nmol/L--drop the zero . . . LDL 110 mg/dl. This woman was advised to take a statin drug by her primary care physician, based on the Friedewald LDL. Instead, she proved to have a far lower LDL. She would not have benefitted from taking a statin drug.

As I've warned many times before: Beware the Friedewald calculated LDL.

Some basic vitamin D issues

24. August 2008 William Davis (7)

The last post on vitamin D raised a number of basic questions among readers. So let me discuss some of these questions one by one. All of them raise important issues surrounding the practical aspects of managing vitamin D in your health.

Anne said:

I think it is important to stress that vitamin D supplementation needs to be continued long term.

I have met too many people who have been prescribed 50,000 IU of D2 for 8-12 weeks and then told to stop because their 23(OH)D went over 30ng/ml. I know one person who's doctor stopped and started the D2 3 times.

Thanks for pointing that out, Anne. Excellent point. I also see doctors do this with statin drugs: start it, check a LDL level which is lower, then think that you're done and stop the drug. What the heck are they thinking?

If vitamin D is not being produced by sun exposure and not obtainable through diet, continued supplementation is necessary, essentially for life.

Twinb asked:

How often you think Vit. D levels should be tested after the initial test is done, especially if the levels are drastically low?

We have used every 6 months in the office. Ideally, levels are in mid-summer and mid- to-late winter in order to gauge the extremes of your seasonal fluctuations. While most adults over 40 fail to fluctuate more than 10 ng/ml in the Wisconsin climate (and this summer, after an initial rainy season early, has been flawlessly bright and sunny, in the high-70s and 80s every single day for months), an occasional person fluctuates more widely. The only way to judge is to check a blood level.

Rich said:

Vitamin D dosage effects appear to be quite idiosyncratic.

Yes, indeed it is. Despite using crude rules-of-thumb, like taking 1000 units of vitamin D per 10 ng/ml desired (a rule I learned from Dr. John Cannell, which he offered fully aware of its inaccuracy), many people will surprise you and have levels that make no sense. Testing is crucial to know your vitamin D level.

Richard asked: Where do we get enough vitamin D wihout worring about laboratory tests?

Well, the entire point of the post was that you absolutely, positively cannot just take vitamin D blindly at any dose and hope that your level is ideal, no more than you can blindly take a dose of thyroid and know you have achieved normal thyroid levels. In my view, vitamin D blood levels are an absolute.

Another simple issue: Don't be afraid of vitamin D. It is, in all practicality, no more dangerous than getting a dark tan. (But, as many of you realize, getting a tan is no assurance of raising vitamin D if you are over 40 years old.)

Wouldn't it be great if someone developed a do-it-yourself-at-home skin test for vitamin D? I know of no effort to develop this, but it would be a huge advantage for all of us.

“How much vitamin D should I take?”

22. August 2008 William Davis (17)

It’s probably the number one most common question I get today:

“How much vitamin D should I take?”

Like asking for investing advice, there are no shortage of people willing to provide answers, most of them plain wrong.

The media are quick to offer advice like “Take the recommended daily allowance of 400 units per day,” or “Some experts say that intake of vitamin D should be higher, as high as 2000 units per day.” Or “Be sure to get your 15 minutes of midday sun.”

Utter nonsense.

The Food and Nutrition Board of the Institute of Medicine has been struggling with this question, also. They have an impossible job: Draft broad pronouncements on requirements for various nutrients by recommending Recommended Daily Allowances (RDA) for all Americans. The Food and Nutrition Board has tried to factor in individual variation by breaking vitamin D requirements down by age and sex, but what amounts to a one-size-fits-nearly-all approach.

Much of the uncertainty over dosing stems from the fact that vitamin D should not be called a “vitamin.” Vitamins are nutrients obtained from foods. But, outside of oily fish, you'll find very little naturally-occurring vitamin D in food. (Even in fish, there is generally no more than 400 units per 4 oz. serving.) Sure, there’s 20 units in an egg yolk and you can activate the vitamin D in a shiitake mushroom by exposing it to ultraviolet radiation. Dairy products like milk (usually) contain vitamin D because the USDA mandates it. But food sources hardly help at all unless you’re an infant or small child.

It all makes sense when vitamin D is viewed as a hormone, a steroid hormone, not a vitamin. Vitamin-no, steroid hormone-D exerts potent effects in tiny quantities with hormone-like action in cells, including activation of nuclear receptors.

It is the only hormone that is meant to be activated by sun exposure of the skin, not obtained through diet. But the ability to activate D is lost by the majority of us by age 40 and even a dark tan is no assurance that sufficient skin prohormone D activation has taken place.

As with any other hormone, such as thyroid, parathyroid, or growth hormones, dose needs to be individualized.

Imagine you developed a severely low thyroid condition that resulted in 30 lbs of weight gain, lose your hair, legs swell, and heart disease explodes. Would you accept that you should take the same dose of thyroid hormone as every other man or woman your age, regardless of your body size, proportion of body fat, metabolism, genetics, race, dietary habits, and other factors that influence thyroid hormone levels? Of course you wouldn’t.

Then why would anyone insist that vitamin D be applied in a one-size-fits-all fashion? (There’s another world in which a one-size-fits-all approach to hormone replacement has been widely applied, that of female estrogen replacement. In conventional practice, there’s no effort to identify need, estrogen-progesterone interactions, nor assess the adequacy of dose, not to mention the perverse non-human preparation used.)

With thyroid hormone, ideal replacement dose of hormone ranges widely from one person to another. Some people require 25 mcg per day of T4; others require 800% greater doses. Many require T3, but not everybody.

Likewise, vitamin D requirements can range widely. I have used anywhere from 1000 units per day, all the way up to 16,000 units per day before desirable blood levels were achieved.

Vitamin D dose needs to be individualized. Factors that influence vitamin D need include body size and percent body fat (both of which increase need substantially); sex (males require, on average, 1000 units per day more than females); age (older need more); skin color (darker-skinned races require more, fairer-skinned races less); and other factors that remain ill-defined.

But these are “rules” often broken. My office experience with vitamin D now numbers nearly 1000 patients. The average female dose is 4000-5000 units per day, average male dose 6000 units per day to achieve a blood level of 60-70 ng/ml, though there are frequent exceptions. I’ve had 98 lb women who require 12,000 units, 300 lb men who require 1000 units, 21-year olds who require 10,000 units. (Of course, this is a Wisconsin experience. However, regional differences in dosing needs diminish as we age, since less and less vitamin D activation occurs.)

Let me reiterate: Steroid hormone-vitamin D dose needs to be individualized.

There’s only one way to individualize your need for vitamin D and thereby determine your dose: Measure a blood level.

Nobody can gauge your vitamin D need by looking at you, by your skin color, size, or other simple measurement like weight or body fat. A vitamin D blood level needs to be measured specifically-period.

Unfortunately, many people balk at this, claiming either that it’s too much bother or that their doctor refused to measure it.

I would rank normalizing steroid hormone-vitamin D as among the most important things you can do for your health. It should never be too much bother. And if your doctor refuses to at least discuss why he/she won’t measure it, then it’s time for a new doctor.

If you’re worried about adding to rising healthcare costs by adding yet another blood test, think of the money saved by sparing you from a future of cancer, heart disease, osteoporosis, diabetes, etc. The cost of a vitamin D blood test is relatively trivial (around $40-50, a fraction of the cost of a one month supply of a drug for diabetes.)

So how much vitamin D should you take? Enough to raise your blood level of 25-hydroxy vitamin D to normal. (We aim for a normal level of 60-70 ng/ml.)

You probably don't take enough fish oil

20. August 2008 William Davis (17)

The results of the recent Heart Scan Blog survey in response to the question: MY DAILY DOSE OF EPA + DHA FROM FISH OIL IS revealed:

Zero--I don't take any
17 (7%) of respondents

Less than 1000 mg per day
24 (10%) of respondents

1000-2000 mg per day
91 (38%) of respondents

2000-3000 mg per day
44 (18%) of respondents

3000-4000 mg per day
40 (16%) of respondents

More than 4000 mg per day
20 (8%) of respondents

Based on the above results, I would say that only a minority of respondents are taking an ideal dose of omega-3 fatty acids. Nearly all of us should consider taking more.

Benefits of omega-3 fatty acids (EPA + DHA) from fish oil begin around a dose of 840 mg per day, according to the GISSI Prevenzione Trial of 1999, an 11,000-participant trial. This dose also corresponds to a quantity of omega-3s that have been shown to raise EPA + DHA blood levels and thereby reduce the notoriously high AA:EPA ratio of Americans.

But what dose is sufficient? What dose is ideal?

Well, the answer to a great degree depends on what you are taking the fish oil for. If being taken to reduce triglycerides and triglyceride-containing lipoproteins, like VLDL and the after-eating (postprandial) IDL, then a higher dose will be necessary. (Triglyceride reduction for the genetically-determined very high triglyceride level of familial hypertriglyceridemia is the FDA-approved indication for prescription Lovaza.)

If you are taking fish oil for treatment of ADHD, depression, or bipolar illness, very high doses are often necessary.

But how about maximal reduction of cardiovascular risk and for control or reversal of atherosclerotic plaque?

This conversation is still evolving. But we can learn some important lessons from three populations of the world that are vigorous consumers of fish:

--The Inuits (aka Eskimos) of Greenland and northern Canada
--The Japanese
--The Bantus of Tanzania who live along Nyasa Lake

All three indigenous populations have several-fold greater intakes of fish and omega-3 fatty acids, have higher blood levels of omega-3 fatty acids, and have enjoyed reduced cardiovascular events, reduced atherosclerotic plaque, or improvement in various surrogates of cardiovascular risk (e.g., Lp(a)).

The most recent addition to this conversation is the ERA JUMP Study, discussed in a previous Heart Scan Blog post. In ERA JUMP, despite being heavy smokers and having other markers for greater risk for heart disease, Japanese men living in Japan had markedly less carotid and coronary plaque, as compared to Caucasian men living in PIttsburgh or Hawaiian men of Japanese descent. The difference appeared to be attributable to serum levels of omega-3 fatty acids.

I believe that the trend is here is to increase the amount of omega-3 fatty acids that most of us take. In the Track Your Plaque program, we have been advocating a rock-bottom starting dose of EPA + DHA of 1200 mg per day. However, I believe that this is due for a change.

We will be increasing the minimum dose for plaque regression and control. Please attend our Webinar this evening for a full, in-depth discussion of the rationale behind this important change.

As always, let me remind you that I am not selling, nor ever have sold, fish oil supplements. If I advocate a specific dose, a higher dose, I do so based on my interpretation of the data and experience with patients, not because I am interested in selling brand X of fish oil.

Vitamin D and HDL

19. August 2008 William Davis (23)

Despite the paucity of scientific documentation of this phenomenon, I am continuing to witness extraordinary increases in HDL cholesterol levels with vitamin D supplementation.

I've touched on the interaction of vitamin D supplementation with HDL in The Heart Scan Blog previously:

Vitamin D: Treatment for metabolic syndrome?

HDL for Dummies

At first, I thought it was attributable to other factors. In real life, most people don't modify one factor at a time. They reduce
processed carbohydrates/eliminate wheat and cornstarch, lose weight, add or increase omega-3 fatty acids from fish oil, begin niacin, increase exercise and physical activity. All these efforts also impact on HDL.

Among the many things I do, I consult on complex lipid (cholesterol) disorders (complex hyperlipidemias) in my office. A substantial number of these people carry a diagnosis of hypoalphalipoproteinemia, a mouthful that simply means these people are unable to manufacture much apoprotein A1, the principal protein of HDL cholesterol particles. As a result, people with hypoalphalipoproteinemia have HDL cholesterol levels in the neighborhood of 20-30 mg/dl--very low. They are also at high risk for heart disease and stroke.

Encourage these people to exercise, attain ideal weight, eliminate wheat and cornstarch: HDL increases 5 mg/dl or so.

Add niacin, HDL increases another 5-10 mg/dl.

Perhaps we're now sitting somewhere around an HDL of 35-40 mg/dl--better, but hardly great.

Add vitamin D to achieve our target serum level . . . HDL jumps to 50, 60, 70, even 90 mg/dl.

The first few times this occurred, I thought it was an error or fluke. But now that I've witnessed this effect many dozens of time, I am convinced that it is real. Just today, I saw a 40-year old man whose starting HDL was 25 mg/dl increase to 87 mg/dl.

Responses like this are supposed to be impossible. Before vitamin D, I had never witnessed increases of this magnitude.

Not all therapies for raising HDL raise the important large (also known as HDL2b) fraction. With lipoprotein analyses, it appears that is principally the large fraction of HDL that rises with vitamin D supplementation.

Why? How?

That I can't tell you. But for those of you struggling with low HDL cholesterols despite your best efforts, vitamin D can make a world of difference.

An interesting corollary: If super-high HDL cholesterols are associated with extreme longevity, as they are with centenarians, does raising HDL to extraordinary levels with vitamin D lead to longer, healthier life, all the way up to age 110 years?

Again, no answers, but an interesting thought. And one I'd bet on. (And I'm not selling vitamin D.)

Weight loss and blood pressure

15. August 2008 William Davis (6)

Here's another thought with regards to time issues with weight loss: reductions in blood pressure (BP).

The previous post talked about how triglycerides initially go up, sometimes way up, when weight drops, only to be followed months later by substantial drops. HDL initially drops in response to the triglyceride fluctuations, only to be followed by a rise.

Blood pressure also shows a curious pattern that is largely dependent on age.

Say someone in their 20s or 30s, for instance, loses 30 lbs (through elimination of wheat and cornstarch, say). BP usually drops within a few weeks, perhaps a month or two at most.

How about someone in their 70s? Say a substantial amount of weight is lost, say 50 lbs over 6 months. BP does indeed drop, but it may require 6 months or longer after weight plateaus for the full effects of BP-reduction to be fully expressed. But it will eventually drop.

Why the age-dependent difference?

It relates to the capacity of arteries to remain flexible and distensible. Over the years, cross-linking of collagen (a structural protein), glycation (glucose molecules attaching to proteins), loss of endothelial responsiveness to generate artery-dilating substances like nitric oxide, and arterial atherosclerotic plaque all all up to making older arteries less able to "relax" and BP to drop.

But given time and the proper effort, BP will eventually drop. Awareness of this time effect can help most people decide better when medications are necessary or if weight loss alone is sufficient to reach BP goals.

"I lost 30 lbs and my triglycerides went . . . up?"

13. August 2008 William Davis (6)

Brad needed to lose weight.

At 6 ft tall, he began the program at 291 lbs, easily 80 lbs overweight. He wore virtually all of it in his belly.

He had laboratory numbers to match: HDL 33 mg/dl, triglycerides 225 mg/dl, LDL (calculated) 144 mg/dl, blood sugar 122 mg/dl (fasting--clearly "pre-diabetic"), c-reactive protein 3.0 mg/dl. Among his lipoprotein abnormalities: small LDL representing 80% of all LDL (no surprise).

Readers of The Heart Scan Blog know that these are the patterns of the carbohydrate-indulgent. I asked Brad to eliminate all wheat flour products, all foods made with cornstarch, and follow a diet rich in healthy oils, raw nuts, vegetables, and lean meats.

Brad returned for a discussion about follow-up basic lipids (cholesterol) values four months later--31 lbs lighter, most of it clearly lost from his abdomen. He claimed he felt more energetic and clear-headed than he had in years.

His lipid panel: HDL 34 mg/dl, LDL 122 mg/dl, triglycerides 295 mg/dl. Brad's smile dissolved. "How could that happen? You said losing weight would make my HDL go up and my triglycerides go down!"

Yes, I had said that. But I was oversimplifying.

The truth is that, when there is weight loss, especially profound weight loss like Brad experienced eliminating wheat and cornstarch products, there is mobilization of fat stores. Fat is stored energy. Energy is stored as . . . triglycerides.

So when there is substantial weight loss, there is a flood of triglycerides in the blood, and triglyceride levels in the midst of weight loss can commonly jump up, not uncommonly to the 200-300+ mg/dl range. When triglycerides go up, there is also a drop in HDL (triglycerides interact with HDL particles, modify their structure and make them more readily destroyed, thereby dropping blood levels). Occasionally, substantial weight loss like Brad experienced will drop HDL really low, as low as the 20's.

Once weight stabilizes, this effect can last up to 2 months before correcting. Only then will triglycerides drop and HDL rise. The rise in HDL occurs even more slowly, requiring several more months to plateau.

In other words, weight loss like Brad's causes triglycerides to increase and HDL to decrease, to be followed later by a drop in triglycerides and a rise in HDL.

I know of no way to block this phenomenon. And perhaps we shouldn't, since this is how fat stores are mobilized and "burned off." Fish oil does blunt the triglyceride rise (perhaps through activation of lipoprotein lipase, an enzyme responsible for clearance of triglycerides), but doesn't eliminate it.

I call these changes "transitional" changes in lipids.

Patience pays. A few more months from now, Brad's numbers will be much happier, as will Brad.

Divorce court for the doctor-patient relationship?

10. August 2008 William Davis (4)

The doctor-patient relationship has gone sour.

This probably comes as no surprise to most of you, particularly if you've been following conversations here in The Heart Scan Blog:

Who is your doctor? discussing the emergence of the physician-as-hospital-employee phenomenon that causes your doctor to become the de facto portal (seller?) of hospital services to you, a model fraught with conflicts of interest.

Exploitation of trust, my observation that the enormous gap in heart disease prevention between the woefully ignorant (by necessity) level of sophistication of the primary care physician and the procedure-obsessed cardiologist leads to an exploitation of humans-for-heart-procedures because of the failure to institute genuine preventive efforts.

Bait and switch , a description of how a minor test or symptom can reap a bonanza of medical testing; a $20 "screening" test yields $10's of thousands in hospital procedures. If it were entirely due to the imprecision of medical testing and detection of disease, that might be forgivable. But it often is not: It has become utterly distorted by the profit model.

Lest you think that I am a kook ranting off in some backwoods corner (Milwaukee), here are the comments of New York Times' Health Editor Tara Parker-Pope in a series called Doctor and Patient, Now at Odds:

Lately I've been hearing a lot from patients who are frustrated, angry, and distrustful of doctors. Their feelings speak to a growing disconnect between doctors and patients and worries that drug companies, insurance rules, and hospital cost-cutting are influencing the care and advice that doctors provide.

Research shows that even among patients who like their personal physicians, there is a simmering distrust of the medical system and the doctors who work inside it.

(There's also a series of candid video interviews with people who echo these sentiments.)

There are a number of reasons for this increasing "disconnect," some of them articulated by Ms. Parker-Pope, others detailed in my blog posts.

The solutions, however, will not be found by advancing technology: the newest robotic surgery, a better defibrillator, a new statin drug, the next best chemotherapeutic agent. It will not be found by adding a new wing to the hospital. It will not be found by the reorganization of healthcare delivery achieved by converting primary care and specialty practice into an arm of hospital care. It will not be improved by employing "hospitalists." It will not emerge from legislation controlling insurance company practices. It certainly will not come from increasing marketing dollars spent by drug companies (who make $4 for every $1 spent on direct-to-consumer marketing).

The solutions will come from shifting the idea of care from a paternalistic, "I'm the doctor and I'll tell you what to do" approach, to the doctor-as-advocate-and-supporter of the patient. The physician should act as someone with a particular sort of expertise that can advise a patient.

But a caveat: The patient MUST be informed.

Proper information will not originate with the doctor. It will originate with internet-based information portals and tools that help you understand the issues, often with far greater depth than your doctor could ever provide. The physician needs to accept this role, one of advocate, adviser, but not of being in charge, not of viewing the patient as profit-center, not as an opponent in a power struggle.

Sadly, the last few years in online information portals has been dominated by the drug company-dominated websites like WebMD, nothing more than a deliverer of the conventional wisdom with nothing whatsoever aimed towards empowering patients in a self-directed healthcare model.

Some people call the emerging new empowered and information-armed patient Medicine 2.0. Unfortunately, Medicine 2.0 will first benefit the intellectual upper crust of Americans, the web-savvy and motivated to engage in health issues. But, give it 10 years, and we will witness the effects on an unprecedented broad scale. Part of the Information Age is acceleration of information dissemination. Imagine your children, facile with a computer mouse, posting comments on FaceBook, doing homework with Google and Wikipedia, now turning their attentions to health.

It will be a startling change.

In the meantime, be wary. Be empowered. Think increasingly about self-direction in your health.

In a comment to the Bait and switch post, Jennytoo offered an insightful response:

You are getting to the essence of the problem, and it's not just cardiology that is rife with what is, at bottom, malpractice.

There is little incentive for the profession as a whole to know anything about or promote prevention, and many incentives from hospitals, drug and insurance companies to stick with the status quo or to change it in their corporate favor. The formulaic, conventional statements purporting to be guidelines for prevention that are put out by various interest groups and in such publications as hospital-sponsored newsletters ("eat a 'balanced diet', avoid stress, etc.") are useless sops to the concept of prevention.

It is, and I fear is going to remain, up to motivated individuals, both physicians and patients, to reshape the system, and it's going to be a long frustrating struggle.

It's my personal conviction that if just 4 things were promoted to the public, and people actually practiced them, we could change the health profiles of the majority of people in this country for the better within two years or less. They are:

(1) education on and promotion of a true low-carbohydrate, whole foods, diet,
(2) measurement and supplementation of Vitamin D3,
(3) supplementation with DHA/EPA (found in Fish Oils), and
(4) measurement and supplementation of intracellular magnesium.

I am not a health professional, and others may want to add to this list, but I don't think any strong case can be made against any of the items. The wonderful and hopeful thing is that each of us can implement them ON OUR OWN, and thereby take charge of our own well-being. (The Life Extension Foundation is one organization which provides access to lab tests you can request on your own.)

If you have a physician who is willing and capable of being your partner, you are richly blessed, and that is the ideal we all should hope for. But in the more likely event that you do not have such a physician, and if your physician demonstrates little potential for becoming one, think about firing the one you have and finding another.

Sometimes we are forced by circumstances, particularly urgent ones, to deal with physicians who are not ideal, but the main impetus for change will come from us, the patients, and the expectations we communicate to our individual doctors. In the meantime, we can be self-reliant in our own prevention practices.

Wow. A woman after my own heart.

How much fish oil is enough?

9. August 2008 William Davis (7)

This post just furthers this line of thinking out loud: How much fish oil is "enough"?

Observations over the last 30 years followed this path: If a little bit of omega-3 fatty acids from fish are beneficial in reducing cardiovascular events, and a moderate intake is even better, is even more better? When have we reached a plateau? When do adverse effects outweigh the benefits?

Some insight can be gained through studies that examined blood levels of omega-3s. Let's take a look at some data from 2002, a comparison of men dying from heart disease vs. controls in the Physicians' Health Study, Blood Levels of Long-Chain n–3 Fatty Acids and the Risk of Sudden Death.

This is a table that shows the blood levels of various fatty acids Group with sudden death vs Control Group:

Several observations jump out:

--The total omega-3 blood content differed significantly, 4.82 vs 5.24% ("Total long-chain n-3 polyunsaturated")
--Total omega-6 content did not differ
--Arachidonic acid (AA) content did not differ
--Linolenic acid content did not differ (i.e., plant sourced omega-3)

The fact that neither omega-6 nor arachidonic acid content differed counters the argument that Simopoulos has made that the omega-6 to omega-3 ratio (intake, not blood levels) is what counts. It also argues against the EPA to AA ratio (and similar manipulations) that some have argued is important. In this study, only the omega-3 level itself made a difference; no ratio was necessary to distinguish sudden death victims vs controls.

Further, quartiles of omega-3 blood levels showed graded reductions of risk:

An omega-3 blood level of 6.87% conferred greatest risk reduction. Depending on the model of statistical analysis, risk reductions of up to 81-90% were observed. Wow.

Taken at face value, this study would argue that:

--An omega-3 fatty acid blood level of 6.87% (or greater?) is ideal
--The omega-3 fatty acid blood level stands alone as a predictor without resorting to any further manipulation of numbers, such as relating EPA and/or DHA to AA levels.

Of course, this is just one study, though an important one. It is also not a study based on any intervention, just an observational effort. But it does add to our understanding.

We will develop these issues further in our upcoming Track Your Plaque Webinar on Wednesday, August 20th, 2008.

Calcium reflects total plaque

4. December 2006 William Davis (0)

People frequently ask, "Why measure coronary artery calcium? My doctor said that calcium only tells you if there's hard plaque, and that hard plaque is stable. He/she says that calcium doesn't tell you anything about soft plaque."

Is that true? Is calcium only a reflection of "hard" plaque? Is hard plaque also more stable, less prone to rupture and causes heart attack?

Actually, calcium is a means of measuring total plaque, both soft and hard. That's because calcium comprises 20% of total plaque volume. Within plaque, there may be areas that are soft (labeled "lipid pool" in the diagram). There are also areas made of calcium (shown in white arcs within the plaque). Even though this is just a graphic, it's representative of what is seen when we perform intracoronary ultrasound of a live human being's coronary artery. In other words, this cross section contains both "soft" (lipid pool) as well as "hard" (calcium) elements.

Is this artery "soft" or "hard"? It's both, of course. The artery compostion can vary millimeter by millimeter, having more soft or hard elements. The artery can also change over time in either direction. Thus, "soft" plaque may indeed be soft today, only to be "hard" in 6 months, and vice versa.

The essential point is that measuring just "soft" plaque provides limited information. What the CT heart scan does is provide a gauge of total plaque, soft and hard, and it does so easily, safely, precisely. If your score increases, the lengthwise volume of total plaque has also grown. If your score decreases, the total amount of plaque has also decreased.

Don't mistake marketing for truth

2. December 2006 William Davis (0)

We're all so inundated with marketing messages for food. Unfortunately, many people confuse the messages delivered through marketing with the truth.

For instance:

Pork: "The other white meat." Pork is a high-saturated fat food.

"Bananas: A great source of potassium." Bananas are a high glycemic index (rapid sugar release), low fiber food.

"Pretzels: A low-fat snack." A high glycemic index food made from white wheat flour. It makes you fat and skyrockets blood sugar.

Jif peanut butter: "Choosy moms choose Jif." Do they also choose hydrogenated fats?

Hi-C: Upbeat jingles like "Who put the straw in my Hi-C fruit drink, a new cool straw that wriggles and bends? Who put the straw in my Hi-C fruit drink, with Vitamin C for me and my friends? Who was that man, I'd like to shake his hand, he made my Hi-C cooler than before!" What about the 25 grams of sugar per 4 oz serving? And the high fructose corn syrup that creates an insatiable sweet tooth, raises triglycrides 30%, and exagerates pre-diabetes?

Marketing is not reliable, unbiased information. If Ford boasts that their cars are superior to GM, do you say "Well then, I need to buy a Ford?" Of course not. Take marketing for what it is: A method of persuading people to buy. It may or may not contain the truth. It's a big part of the reason Americans are the fattest people on earth and are experiencing an explosion of chronic diseases of excess.

Tattered Red Dress

1. December 2006 William Davis (0)

"Are you taking your health to heart? Perhaps you understand the importance of eating a diet low in cholesterol or getting 30 minutes of exercise a day. But do you know your own risk of developing cardiovascular disease?

It’s time to take your heart health personally. Heart disease is the No. 1 killer of American women — and that means it is not “someone else’s problem.” As a woman, it’s your problem.

That’s where the Go Red Heart Checkup comes in. This comprehensive evaluation of your overall heart health can help you now and in the future. By knowing your numbers and assessing your risks now, you can work with your doctor to significantly reduce your chances of getting heart disease tomorrow, next year, or 30 years from now!"

So reads some of the materials promoted by the American Heart Association Red Dress campaign to increase awareness of heart disease in women. The effort is well-intended. There is no doubt that most women are unaware of just how common coronary disease is in females.

But I've got a problem with the solutions offered. "Know your numbers"? Eat healthy, don't be overweight, be active, don't smoke. That's the gist of the program's message--nothing new. In 2006, why would some sort of screening effort for detectin of heart disease not be part of the message? Why isn't there any message about the real, truly effective means to detect hidden heart disease in women--namely, heart scanning?

Does a 58-year old woman with normal blood pressure, LDL 144, HDL 51, 20 lbs overweight have hidden heart disease? I've said it before and I'll say it again: You can't tell from the numbers. She could die of a heart attack tomorrow without warning, or maybe she'll be dancing on our graves when she's 95 and never have experienced any manifestation of heart disease. The numbers will not tell you this.

I'm glad the American Heart Association has seen fit to invest its sponsors' money in a campaign to promote prevention. I wish they hadn't fallen so far short of a truly helpful message. Perhaps the sponsors (like Pfizer, maker of Lipitor) will benefit, anyway.

Panic in the streets

29. November 2006 William Davis (0)

Several days ago, I wrote about a local prominent judge in my neighborhood who was unexpectedly found dead in bed of a heart attack at age 49.

As expected, I've received multiple calls from patients and physicians who want heart catheterizations. For instance, an internist I know called me in a panic. He asked that I perform a heart catheterization in a patient with a heart scan score of 768. I've been seeing this patient for about a year. He's without symptoms, even with strenuous exercise; stress tests (i.e., tests of coronary bloow flow) have been normal.

I remind patients and colleagues every day, day in day out: Having a heart scan score revealing some measure of coronary plaque is not a sufficient reason by itself to proceed with procedures. Fear of suffering a fate like the unfortunate judge is also not a reason to proceed with procedures.

Increased awareness of the gravity of heart disease is a good thing. Some good can come out of a needless tragedy like this. The lesson from the judge's unfortunate experience: he needed a CT heart scan. I'm told that the judge's doctor advised him that a heart scan was a waste of time. I hope that appropriate legal action for negligence is taken by the judge's family against this physician.

Not doing a heart scan is wrong. That's the lesson to learn. The lesson is not that everybody with coronary plaque needs a procedure. Had the judge undergone a simple heart scan, intensified prevention could have been instituted and he'd still be alive with his wife and children today.

The indications for procedures are unchanged by your heart scan. If a stress test is abnormal and indicates poor flow to a part of the heart, that would be a reason. If symptoms like chest discomfort or breathlessness appear, that's an indication. If there's evidence of poor heart muscle contraction, that's a reason to proceed with a procedure. But just having coronary plaque is not a sufficient reason.

Heart scan curiosities 1

27. November 2006 William Davis (3)

Heart scans often reveal more than coronary plaque. From time to time, I'll show some curious findings that people have displayed during routine heart scans.

This 65-year old man had a relatively low heart scan score of 73, but showed an impressive quantity of calcification of his pericardium, the usually soft-tissue sack that encases the heart. The calcified pericardium is the white arcs that surround the heart in the center of the image.

Thankfully, because he's without any symptoms of breathlessness, excessive fatigue, or leg swelling, he won't need to have it surgically corrected. When the pericardium becomes rigid and encircles the heart, it can literally squeeze the heart, a condition called "constrictive pericarditis". The surgery is pretty awful.

This man's calcified pericardium likely resulted from one or more viral infections over his lifetime.

Annual physical

26. November 2006 William Davis (0)

A judge who lives in my neighborhood was found dead in his bed this week from a heart attack. He was 49 years old. His teenage kids found him and performed CPR, but he was cold and long-gone by then.

A close friend of the judge told me that he'd passed an annual physical just weeks before.

This sort of tragedy shouldn't happen. It is easily--easily--preventable. Had this man undergone a heart scan, a score of at least 400 if not >1000 would have been uncovered, and appropriate preventive action could have been taken. The conversation could have centered around the strategies to correct the patterns that triggered his plaque and how he could reduce his score.

Of course, hospitals make use of stories like this to fuel fear that brings hordes to their wards for procedures. Would the judge have required a procedure to save his life, had his heart disease been diagnosed at his annual physical? Not necessarily. Hospitals and cardiologists would try to persuade you that procedures have an impact on mortality. This is simply not true. In fact, the mortality benefits of procedures are questionable except in the midst of acute illness (e.g., unstable chest pain symptoms or heart attack).

Don't be falsely reassured by passing a physical. A physical does nothing to screen you for heart disease. An EKG and stress test, if included, is a lame excuse for heart disease screening. Remember that a stress test is a test of coronary blood flow, not for the presence of coronary plaque. The unfortunate judge most likely had a 30% "blockage" that did not block flow, but ruptured and closed an artery off sometime in the night when he died. A stress test even on the day of his death would not have predicted this.

A CT heart scan would have uncovered it easily, unequivocally, safely.

A curious case of regression

25. November 2006 William Davis (0)

Randi came to me at age 43. Before I'd met her, she'd undergone two heart scans about one year apart. The initial score was 57--not terribly high, but very high for a 41-year old, pre-menopausal female. Recall that rarely do women have any heart scan score above zero before age 50. Randi's 2nd scan had yielded a score of 72, a 27% increase.

Randi even had her lipoproteins assessed and she had the dreaded Lp(a). So when I met her, we discussed the possible choices in Lp(a) treatment: niacin and estrogens as primary treatment, along with LDL reduction to rock-bottom numbers, along with adjunctive DHEA, almonds, ground flaxseed, and fish oil. Sandi was okay with the adjunctive treatments and was already slender and active (BMI <25), and did not show Lp(a)'s evil partner, small LDL. But Randi had no interest in estrogens, even bio-identical preparations, because of the usual uncertainties associated with estrogen replacement. She also proved to be one of the people truly intolerant to anything but the most minute dose of niacin, experiencing prolonged flushing and abdominal cramps with any dose >250 mg.

Randi even attempted a trial of the Mathias Rath concoction of high-dose vitamin C, lysine, and proline as treatment for Lp(a), but we saw no effect on Lp(a).

Unfortunately, this left Randi's Lp(a) essentially uncorrected. Another scan one year later: 90, another 25% increase. 18 months after that, another scan: 120, a 30% increase.

Now 47-years old, Randi had resigned herself to not being able to control her plaque. We'd run out of options. At that point, I'd started to have everyone's vitamin D blood level assessed and then replaced with vitamin D. I did this with Randi, too.

A year after her last scan, she underwent another. The score: 92, a 23% reduction--substantial reversal following a course of unrelenting progression.

Randi and I, of course, both rejoiced with this unexpected success. But it raised some interesting questions: How important is Lp(a) when vitamin D is normalized and small LDL is not a part of the picture? How consistent with regression be with this strategy over time? Would normalization of vitamin D have stopped plaque from becoming established in the first place?

I hope these issues will clarify over time. For now, I'm thrilled with Randi's success. She remains on her present, "incomplete", though successful program.

Note: I would not ordinarily advise a young woman to undergo serial heart scanning with this frequency. Randi had unusual access to a scan center through a relationship with the staff. I am nonetheless grateful for the lessons her experience have taught us.

Fortune teller

25. November 2006 William Davis (0)

Whenever your doctor uses your cholesterol values--total, LDL, HDL, triglycerides--to judge your heart disease risk, he/she is trying to act as your fortune teller.

In some states, fortune telling is illegal, a misdemeanor. The New York State lawbooks say:

A person is guilty of fortune telling when, for a fee or compensation which he directly or indirectly solicits or receives, he claims or pretends to tell fortunes, or holds himself out as being able, by claimed or pretended use of occult powers, to answer questions or give advice on personal matters or to exorcise, influence or affect evil spirits or curses; except that this section does not apply to a person who engages in the aforedescribed conduct as part of a show or exhibition solely for the purpose of entertainment or amusement.
(Source : Wikipedia)

Rather than occult powers, your physician claims to use "medical judgement" to tell your fortune. Except for that distinction, it might be construed as a misdemeanor.

Let's take three typical examples:

58-year old Laura has a high LDL of 195 mg/dl. Her HDL is 52 mg/dl, triglycerides 197 mg/dl. Does she have heart disease?

51-year old Jonathan has an LDL of 174 mg/dl, HDL 34 mg/dl, triglycerides 156 mg/dl. Does Jonathan have heart disease?

71-year old Marian has an LDL cholesterol of 135 mg/dl, HDL 84 mg/dl, triglycerides of 67 mg/dl.

None of the three have symptoms. They all feel well. Nobody is taking a statin cholesterol drug or other agent that would modify the numbers. Jonathan is around 30 lbs overweight. Nobody has an impressive family history of heart disease.

Can you tell who has heart disease and who doesn't? If you can, you're smarter than I am, because I certainly can't tell. But your doctor tries to divine your future by looking at these numbers.

Do they know something that we don't know? No. It's a crude odds game, a guessing game. A guessing game that frequently comes up on the losing end.

These are three real people. Laura, despite her high LDL, has no identifiable coronary heart disease. Jonathan has advanced coronary disease. These were his numbers just prior to his stent. Marian has a moderate quantity revealed by a CT heart scan score of 419.

Don't even try predicting your future from your cholesterol numbers--it simply can't be done. Every day, I see patients and physicians beating their heads over this dilemma. Telling your fortune using pretended occult powers is illegal. Telling your fortune using cholesterol numbers should be, too.

If you want to know if you have coronary plaque, that's the role of the CT heart scan. Plain and simple.

Heart scan score drops like a stone

23. November 2006 William Davis (2)

Matt was dumbfounded when he found out about his heart scan score of 317 in the summer of 2005.

Earlier that year he'd unintentionally lost 20 lbs. in the space of two months and was feeling awful. He was diagnosed with diabetes and put on several medications. He told me that the heart scan score was just adding insult to injury.

As you'd expect in someone with diabetes, Matt had a low HDL, increased triglycerides, and small LDL. Blood pressure and inflammation (C-reactive protein) were issues as well.

Matt's primary care physician had put him on a statin cholesterol drug as soon as he heard about Matt's heart scan score, so we kept this going. What Matt's primary care physician didn't know was that his "true" LDL had been much higher than the conventional calculated LDL had suggested, so the statin agent was a reasonable solution. (Matt was also not terribly motivated to make dramatic changes in lifestyle or food choices. The statin drug was a compromise.)

We added fish oil and vitamin D to his regimen. Though recent data have cast doubt on the value of treating homocysteine levels of around 12.5, Matt's much higher value of 28 was treated with vitamins B6, B12, and folic acid, with a resultant homocysteine of 7.6.

17 months into the Track Your Plaque approach, and Matt's repeat heart scan score: 244, a 23% reduction.

How's that for an early Christmas gift?

"You don't have a uterus. You don't need progesterone"

21. November 2006 William Davis (2)

I was talking with a hospital nurse recently who told me about her lack of energy, blue moods, and other assorted complaints. At age 49, she was exasperated. So I suggested that she ask her gynecologist about progesterone cream.

The gynecologist advised her, "You don't have a uterus. You don't need progesterone." He went on to explain that the only reason to take progesterone was to prevent uterine cancer caused by estrogen.

Then what about progesterone's weight loss benefits? It's effects on increased energy, improved mood, deeper sleep? These benefits, of course, have nothing to do with the uterus.

I've witnessed these benefits in women many times, both in the peri-menopausal period (which starts around your late 30's) and menopause.

Why talk about progesterone when our focus is heart disease and reduction of heart scan scores? Because if progesterone in a woman helps her feel better, more upbeat, and accelerates weight loss, she's more likely to succeed in her plaque-control program.

For additional comments on progesterone, read the Track Your Plaque interview with women's hormone expert, Dr. Nisha Jackson, Females, hormones, and weight control:
An interview with Dr. Nisha Jackson found at http://www.cureality.com/library/fl_04-008njacksonhormones.asp. Dr. Jackson also has a book available called "The Hormone Survival Guide to Perimenopause".

Or, read Dr. John Lee's pioneering books, What Your Doctor May Not Tell You About Menopause: The Breakthrough Book on Natural Hormone Balance and What Your Doctor May Not Tell You About Premenopause: Balance Your Hormones and Your Life from Thirty to Fifty . (An edition that combines the two books is available, also.)
