60-year old man dies of high cholesterol

Never saw a headline like this? Neither have I. That's because it doesn't happen.

Cholesterol doesn't harm, maim, or kill. It is simply used as a crude--very crude--marker. It is, in reality, a component of the body, of the cell wall, of lipoproteins (lipid-carrying proteins) in the bloodstream. It is used a an indirect gauge, a "dipstick," for lipoproteins in the blood to those who don't understand how to identify, characterize, and quantify actual lipoproteins in the blood.

Cholesterol itself never killed anybody, any more than a bad paint job on your car could cause a fatal car accident.

What kills people is rupture of atherosclerotic plaque in the coronary arteries. For all practical purposes, you must have atherosclerotic plaque in order for it to rupture (much like a volcano erupts and spews lava). It's not about cholesterol; it's about atherosclerotic plaque. Plaque might contain cholesterol, but cholesterol is not the thing itself that causes heart attack and death.

So why do most people obsess about cholesterol? Good question. It is, at best, a statistical marker for the possibility of having atherosclerotic plaque that ruptures. High cholesterol = higher risk for heart attack, low cholesterol = lower risk for heart attack. But the association is weak and flawed, such that people with high cholesterol can live a lifetime without heart attack, people with low cholesterol can die at age 43.The same holds true for LDL cholesterol, you know, the calculated value based on flawed assumptions about LDL's relationship to total cholesterol, HDL cholesterol, and VLDL cholesterol.

A crucial oversight in the world of cholesterol: There are many other factors that cause atherosclerotic plaque and its rupture, such as inflammatory phenomena, calcium deposition, artery spasm, hemorrhage within the plaque itself, degradative enzymes, etc., none of which are suggested by cholesterol measures.

But one observation has held up, time and again, over the past 40 years of observations on coronary disease: The greater the quantity of coronary atherosclerotic plaque, the greater the risk of atherosclerotic plaque rupture. An increasing burden of atherosclerotic plaque along the limited confines of coronary arteries, just a few millimeters in diameter and a few centimeters in length, is like a house of cards: It's bound to topple sooner or later, and the bigger it gets, the less stable it becomes.

If you are concerned about future potential for heart disease and heart attack, don't get a cholesterol panel. Get a measure of coronary atherosclerotic plaque.

Back to basics: Coronary calcium

After having my attentions pulled a thousand different directions these past 6 months, with the release of Wheat Belly and all the wonderful media attention it has attracted, I've decided to pick up here with a series of discussions about the fundamental issues important to the Track Your Plaque program and prevention and reversal of coronary atherosclerotic plaque.

I fear the discussions at times have drifted off into the exotic. This is great because this is how we learn new lessons, but we can never lose sight of the basics, else we risk losing control over this disease.

Imagine you've got a beautiful new car. You wax it, gap the spark plugs, rotate the tires, etc. and it looks brand-new, just like it came off the dealer's lot. 50,000 miles pass, however, and you realize you've forgotten to change the oil. Ooops! In other words, no matter how meticulous the attention to transmission, tires, and paint job, neglect of the most basic responsibility can ruin the whole thing. We can't let that happen with heart health.

If we propose to reverse coronary atherosclerotic plaque, we've got to have something to measure. First, it tells us whether we have atherosclerotic plaque in the first place, the stuff that accumulates and blocks flow and causes anginal chest pains, and ruptures like a little volcano and causes heart attacks. Second, it gives us something to track over the years to know whether plaque has grown, stopped growing, or been reduced. Without such a measure, you will be driving without a speedometer or odometer, just guessing whether or not you've gotten to your destination.

Of course, the conventional approach to heart disease and heart attack is not to track atherosclerotic plaque in your coronary arteries, but to track some distant "risk factor" for atherosclerotic plaque, especially LDL cholesterol. But LDL cholesterol is flawed at several levels. First, it is calculated, not measured. The nearly 50-year old Friedewald equation used to calculate LDL cholesterol is based on several flawed assumptions, yielding a value that can be 20, 30, or 50% inaccurate as a rule, only occasionally generating a value close to the real value. (No point in publicizing this problem, of course: Why compromise a $27 billion annual cash cow?) It also ignores the effect of diet. (No, cutting fat does not reduce LDL for real, only the calculated value. Cutting carbohydrates, especially wheat--"healthy whole grains"--slashes measured LDL values like NMR LDL particle number and apoprotein B.)

But all risk factors are, at best, snapshots of the situation at that moment in time. They change from day to day, week to week, month to month, year to year. If you do something dramatic in health, like lose 50 pounds, you can substantially change your risk factors values, like LDL cholesterol and HDL cholesterol. But you may not modify the amount of atherosclerotic plaque in your heart's arteries.

Measuring the amount of atherosclerotic plaque in your heart's arteries is, in effect, a cumulative expression of the effects of risk factors up until the moment of measurement.

There are several stumbling blocks, however, in the concept of measuring coronary atherosclerotic plaque. We cannot measure all the unique components of plaque, such as fibrous tissue like collagen, or degradative enzymes like collagenases, or inflammatory proteins like matrix metalloproteinase, or the debris of hemorrhage and inflammation. We struggle to contemporaneously mix in measures of bloodborne inflammation, coagulation and viscosity, and physiological phenomena of the artery itself, like endothelial dysfunction, medial (muscle) tone, and adventitial fat.

So we are left with semi-static measures of total coronary atherosclerotic plaque like coronary calcium, obtainable via CT heart scans as a calcium "score." No, it is not perfect. It does not reflect that moment's blood viscosity, it does not reflect the inflammatory status of the one nasty plaque in the mid-left anterior descending, nor does it reflect the irritating sheer effects of a blood pressure of 150/95.

But it's the best we've got.

If anyone has something better, I invite you to speak up. Carotid ultrasound, c-reactive protein, ankle-brachial index, stress nuclear studies, myoglobin, skin cholesterol, KIF6 genotype . . . none of them approach the value, the insight, the trackability of actually measuring coronary atherosclerotic plaque. And the only method we've got to gauge coronary atherosclerotic plaque that is non-invasive and available in 2012? Yup, a good old CT heart scan calcium score.

Myocardial infraction

I've seen a few heart attacks this past year . . . but none in the people who follow this program.

I saw a heart attack in a priest, a wonderful man who was unable to say "no" to his parishioners who insisted on bringing pies, cakes, and cookies every day.

I saw an impending heart attack in a 74-year old man, a football coach who thought the whole wheat-free, low-carb thing was some wacko trend. Four stents later, he's changed his mind.

A 69-year old woman had to be hospitalized for heart failure due to partial closure of an artery. She repeatedly told me that she simply could not follow the diet because it was "too restrictive."

There were a few others. Interestingly, all felt they were eating healthy, minimizing junk foods and avoiding fatty foods. None were wheat-free nor restricted carbohydrates.

In other words, in the people who follow the basic advice of the Track Your Plaque program to do such simple things as eliminate wheat, don't indulge in junk carbohydrates, normalize vitamin D status, supplement omega-3 fatty acids, supplement iodine and correct any thyroid dysfunction . . . well, they have no heart attacks.

Diet is superior to drugs

Might-o’chondri-AL left this wonderful record of his lipoprotein experience in the comments to the last Heart Scan Blog post. It is a great example of what is achievable with diet and a few supplements . . . without drugs.


(A) Jan. 2011 1st ever NMR lipo-protein analysis was done after 4 months of consistent home food prep of pretty low fat (only olive oil and 1 tablespoon coconut oil daily) but plenty of whole wheat and half potatoes:
* LDL # of particles (P) = 1,676 in nmol/L————being a LDL cholesterol (C) reading of 139 mg/dL
* small LDL # P = 1,021 nmol/L —————yikes! you advise smLDL be less than 117 nmol/L
* HDL # of particles = 28.8 umol/L ————–being a HDL C reading of 45 mg/dL
* Triglycerides = 90 mg/dL ————– true, I never struggled with my weight

(B) May 2011 2nd NMR after another 4 months but added in more fat (1 teaspoon highly concentrated fish oil daily, 90% chocolate, handfulls of nuts, more olive oil and kept coconut oil at 1 tablespoon daily for a controlled experiment), added 500 mg Niacin 3 times a day (in stages up to1,500 mg. total daily), 6000 IU daily vitamin D, deliberately cut out all grains except for social politeness and substituted in daily Koji fermented brown rice (rustic Amazake):
** LDL # P……………= 976 nmol/L ——————————– being LDL C of 100 mg/dL
** small LDL # P …. = 96 nmol/L ——————————– nice surprise
** HDL # P ………… = 27.3 umol/L ——————————being an increase to HDL C of 64 mg/dL
** Triglycerides …… = 42 mg/dL ——————————– despite daily carbs over 150 gr. daily

(C) Dec. 2011 3rd NMR after another 7 more months thinking Doc’s advice is worthwhile I added in yet more fat (mainly daily 2 tablespoons of coconut oil, more 90% chocolate), bumped Niacin up to 1,000 mg twice a day (2,000 mg. total daily), cut out the Amazake, kept up the vitamin D adding daily vitamin K & daily ate main mid-day meal out as lunch on spicy Thai & Chinese fish/shrimp/soup/rice meals (my next control):
*** LDL # P ………. = 764 nmol/L ————— being LDL C of 107 mg/dL ( 2x coconut’s saturated fat)
***small LDL # P… = less than 90 nmol/L ——–surprised me NMR can’t count lower
***HDL # P ……… = 41.4 umol/L ——————– being an increase to HDL C of 88 mg/dL
*** Triglycerides ….= 43 mg/dL ——————- daily carbs below ~ 120 gr. & lost too much weight

Isn't that great? Spectacular job, Might!

MIght achieved values that are superior to that achievable with, say, a high-dose statin strategy. Statins only reduce total LDL particles, reducing small LDL in a non-selective way. And, of course, this diet does not cause muscle aches, memory loss, nor liver problems.

Something to consider: As the diet has become so effective, we can reduce our reliance on niacin. In fact, the benefits of niacin diminish substantially, as small LDL is reduced, HDL increased, triglycerides decreased, and postprandial lipoproteins subdued with the diet only.

Low-carb is heart healthy

Anybody following the discussions in these pages know that: Limiting carbohydrate intake reduces risk for coronary heart disease and heart attack.

First of all, why do conventional diets advocate restricting saturated and total fat? From the standpoint of surrogate markers of cardiovascular risk, cutting saturated and total fat reduces total cholesterol; reduces calculated LDL cholesterol; and may reduce c-reactive protein modestly (an index of inflammation). It also increases blood sugar and HbA1c (reflecting the prior 60 days blood sugars), increases glycation of the proteins of the body leading to cataracts, arthritis, and hypertension.

Problem: Total cholesterol is a combination of HDL cholesterol, an estimate of VLDL cholesterol (triglycerides), and LDL cholesterol. It is a composite of both "good" things (HDL) and "bad" things (LDL and VLDL). Cutting saturated and total fat results in reduced HDL, increased VLDL/triglycerides, and a reduction in calculated LDL. Pretty weak stuff. The last item, i.e., reduction in calculated LDL, is not even a real phenomenon. In fact, the net effect in most genotypes (genetic types) may be negative: increased heart disease risk.

In contrast, what is the effect of reducing carbohydrate without restricting fat? (In the approach I use, we start with elimination of the most destructive of carbohydrates, wheat, followed by reducing exposure to other carbohydrates, especially cornstarch and corn products, sugar, and oats.) If, say, we cut carbohydrate intake into the range of a truly low-carbohydrate diet of 10-15 grams per meal ("net" carbs, or total carbohydrates minus fiber), then we witness a number of metabolic transformations:

Reduced fasting triglycerides and VLDL
Reduced postprandial (after-eating) triglycerides, chylomicrons, and chylomicron remnants
Increased HDL and shift towards large HDL particles (presumably more protective)
Reduced small LDL particles
Reduced glycation and oxidation of small LDL particles
Reduced hemoglobin A1c
Reduced c-reactive protein and other inflammatory markers
Reduced blood pressure

By slashing carbohydrates, we also witness weight loss from visceral fat, reversal of pre-diabetes and diabetes, and reduced phenomena of glycation. And, if the wheat-free part of low-carb is maintained, you can also see marked improvement in gastrointestinal health, relief from joint pains, relief from leg edema, relief from migraine headaches, improved behavior and ability to concentrate in children with impaired learning, ADHD, and autism, better mood, deeper sleep. You will see multiple inflammatory and autoimmune diseases improve or completely relieved, such as rheumatoid arthritis and ulcerative colitis.

Having personally gone down the diabetic path and back by cutting the fat in my diet, now maintaining a HbA1c of 4.8% with fasting glucose 84 mg/d; (without medications), there should be no remaining doubt: Low-carb diets, especially if wheat-free, dramatically reduce the factors leading to heart disease; low-fat diets worsen the factors leading to heart disease.

Mocha Walnut Brownies

Richer than a cookie, heavier than a muffin, brownies are ordinarily an indulgence that leaves you ashamed of your lack of restraint. Have one . .  . or two or three, and you will surely pack on a pound of belly fat.

But these mocha walnut brownies, as with other recipes I provide, will not pack on the pounds. With no wheat to trigger appetite, nor any readily-digestible carbohydrate to generate blood sugar highs and lows, you can have a nice brownie or two or three and nothing bad happens: You don’t send blood sugar sky-high, don’t trigger formation of small LDL particles and triglycerides, you don’t trigger appetite, you don’t gain a pound of belly fat. You simply have your brownie(s) and enjoy them.

Serve these brownies plain or topped with cream cheese, natural peanut or almond butter, or dipped in coffee.


Ingredients:
8 ounces unsweetened baking chocolate (100% chocolate)
4 tablespoons coconut oil or butter, melted
2 large eggs, separated
½ cup coconut milk (or sour cream)
2 teaspoons vanilla extract
2 cups ground almonds
2 tablespoons coconut flour
1 cup chopped walnuts
¼ cup unsweetened cocoa powder
2 teaspoons instant espresso
Sweetener equivalent to 1 cup sugar or to taste (e.g., liquid stevia, Truvía, erythritol)


Preheat oven to 350º F.

Melt chocolate using double boiler method or in 15-second increments in microwave. Stir in melted coconut oil or butter.

In small bowl, beat egg whites until frothy. Add egg whites, egg yolks, coconut milk, and vanilla extract to chocolate mixture and mix thoroughly by hand.

In separate bowl, combine ground almonds, coconut flour, walnuts, cocoa powder, espresso, and sweetener. Mix thoroughly.

Add dry mix to chocolate mix and mix together thoroughly. If dough is too stiff, add additional coconut milk, one tablespoon at a time.

Place mixture in 9-inch baking pan and bake for 25 -30 minutes or until toothpick withdraws dry.

Are you hungry?

Eliminate modern high-yield semi-dwarf Triticum aestivum . . . and what is the effect on appetite?

A reduction in appetite is among the most common and profound experiences resulting from wheat elimination. I know that I have personally felt it: Wake up in the morning, little interest in breakfast for several hours. Lunch? Maybe I'll have a few bites of something. Dinner . . . well, I'd like to exercise first.

The wheatless report that:

--Appetite diminishes to the point where you can't remember whether you've eaten or not. It is not uncommon to miss a meal, perfectly content. Calorie intake drops by 400 calories per day, on average, calories you otherwise would not have needed but all went to . . . you know where.
--Hunger feels different: It's not the gnawing, rumbling hunger that plagues you every 2 hours. In its place, you will find that hunger feels like a soft reminder that, gee, maybe it's time to have something to eat because you haven't had anything in--what?--4 to 6 hours. And it's a subtle reminder, not a desperate hunt that makes you knock people aside at the food bar, steal coworkers' lunches stored in the refrigerator, salivating at the mere thought of food.
--The simplest foods satisfy--It no longer requires an all-you-can-eat buffet to satisfy, but a few small pieces of healthy food. (Yeah, but what happens to revenues at Kraft, Nabisco, and Kelloggs, not to mention the revenues at agribusiness giants ADM and Monsanto? Slash consumption by, say, 30%, you likewise slash revenues by 30%. What would shareholders say?)
--Even prolonged periods of not eating, i.e., fasting, is endured with ease.

Hunger and the relentless search for something to eat disappear for most people. By eliminating the appetite-stimulating properties of wheat, we return to a natural state of eating for sustenance, to satisfy physiologic need. We are no longer victims of this incredibly powerful appetite-stimulant called gliadin from wheat.

This is why many diets fail: They fail to remove this powerful appetite stimulant. You might eat only lean meats, limit your calories, and exercise 90 minutes per day, but as long as the gliadin protein is pushing your appetite button, you will want to eat more or you will have to mount monumental willpower to resist it. You can lose 20 pounds on phase 1 of the South Beach diet, for instance, only to regain it in phases 2 and 3 when "healthy whole grains" are added back.

So the key is to remove the gliadin protein from your life, i.e., eliminate all things wheat.

 

Chocolate . . . for adults only

If you've got a serious chocolate addiction and you'd like to make it as healthy as possible, give this X-rated dark chocolate a try.
I call it X-rated because it is certain to not satisfy young, sugar-craving palates, but is appropriate for only the most serious chocolate craver. This is a way to obtain the rich flavors and textures of cocoa, the health benefits (e.g., blood pressure reduction, antioxidation) of cocoa flavonoids, while obtaining none of the sugars/carbohydrates . . . and certainly no wheat!

It is easy to make, requiring just a few ingredients, a few steps, and a few minutes. Set aside and save for an indulgence, e.g., dip into natural peanut or almond butter.

Ingredients:
8 ounces 100% unsweetened cocoa
5 tablespoons coconut oil, melted
1/2 cup dry roasted pistachios
1/4 cup whole flaxseeds or chia seeds
Truvia or other non-aqueous sweetener

Using double-boiler method, melt cocoa. Alternatively, melt cocoa in microwave in 15-20 second increments. Stir in coconut oil, pistachios, and flaxseeds or chia seeds. Stir in sweetener, mixing thoroughly. (Note that the sweetener must be non-aqueous, as water-based sweeteners will separate in the oils.)

Lay a sheet of parchment paper out on a large baking pan. Pour chocolate mixture slowly onto paper, tilting pan carefully to spread evenly until thickness of thick cardboard obtained. Place pan in refrigerator or freezer for 20 minutes.

Remove chocolate and break by hand into pieces of desired size.

"Friday is my bad day"

At the start, Ted had a ton of small LDL particles. His starting (NMR) lipoprotien values:

LDL particle number: 2644 nmol/L

Small LDL: 2301 nmol/L

In other words, approximately 85% of all LDL particles were abnormally small. I showed Ted how to use diet to markedly reduce small LDL particles, including elimination of wheat, limiting other carbohydrates, and even counting carbohydrates to keep the quantity no higher than 15 grams per meal ("net" carbs).

Ted comes back 6 months later, having lost 14 pounds in the process (and now with weight stabilized). Another round of lipoproteins show:

LDL particle number: 1532 nmol/L

Small LDL: 799 nmol/L

Better, but not perfect. small LDL persists, representing nearly 50% of total LDL particle number.

So I quiz Ted about his diet. "Gee, I really stick to this diet. I have nothing made of wheat, no sugars. I count my carbs and I almost never go higher . . . except on Fridays."

"What happens on Friday?" I asked.

"That's when I'm bad. Not really bad. Maybe just a couple of slices of pizza. Or I'll go out for a big custard cone or something. That wouldn't do it, would it?"

That's the explanation. Your liver is well-equipped to recognize normal, large LDL particles. Large LDL particles therefore "live" for only a couple of days in the bloodstream. But the human liver does not recognize the peculiar configuration of small LDL particles, so it lets them pass--over and over and over again. The result: Once triggered by, say two slices of pizza, small LDL particles persist for 5 days, sometimes longer.

So Ted's one "bad" day per week is enough to allow a substantial quantity of small LDL particles to persist. While a fat indulgence (if there is such a thing) pushes large LDL up, the effect is relatively short-lived. Have a carbohydrate indulgence, on the other hand, and small LDL particles persist for up to a week. It means that Ted's one "bad" day per week is enough to allow his small LDL particles to persist at this level, preventing him from gaining full control over coronary plaque.

It also means that, if you have blood drawn for lipoprotein analysis but had a carbohydrate goodie within the previous week, small LDL particles may be exaggeratedly high.

HDL 80 mg/dl

More and more people in my clinic are showing HDL cholesterol values of 80 mg/dl or higher, males included.

Think about it: Nationwide, average HDL for males is 42 mg/dl and for females 52 mg/dl. Even though these average values are generally regarded as favorable, HDL cholesterol values at these levels are nearly always associated with higher levels of triglycerides, postprandial (after-eating) lipoprotein abnormalities, and excessive quantities of small LDL particles.

HDL particles are, of course, protective and are powerfully anti-oxidative. Higher levels of HDL have been associated with reduced potential for cancer, as well as reduced risk for heart disease.

Following the simple regimen that we follow to gain control over coronary plaque has therefore increased levels of HDL to heights that are uncommon in the rest of the population, levels that readily top 80, 90, or 100 mg/dl. That regimen includes:

1) Elimination of all wheat--Yes, consumption of "healthy whole grains" sets you up to have lower HDL levels; elimination of wheat increases HDL.
2) Limited carbohydrate consumption--While eliminating wheat is a powerful nutritional strategy to increase HDL, non-wheat carbohydrates like quinoa, millet, beans, rice, and fruit can still cause high triglycerides that lead to reduced levels of HDL. Limited exposure helps keep HDL at higher levels.
3) Omega-3 fatty acid supplementation--Because omega-3 fatty acids reduce both triglycerides and blunt the postprandial rise in lipoproteins that can cause HDL degradation, HDL rises with omega-3s from fish oil.
4) Vitamin D supplementation--The effect is slow, but it is BIG. HDL just goes up and up and up over about 2 years of supplementation. Before vitamin D, HDL levels of 60 mg/dl were the best I could hope for in most people. Now 80 mg/dl is an everyday occurrence.

Other factors can also be used to increase HDL levels, such as weight loss, red wine and alcohol, exercise, cocoa flavonoids, green tea, and niacin. But following the regimen above sends HDL through the roof in the majority.

Are endogenous nutritional supplements better?

Just a muse.

Endogenous substances are those that are already contained within our bodies. They are part of basic human equipment.

Exogenous substances are those that come from outside of our bodies. This includes various substances in foods, drugs (most, though not all), and pesticides.


I often mull over all of the tools we use in the Track Your Plaque program to achieve control over this thing called coronary plaque. It struck me that just about all the supplements we use that seem to provide outsized benefits are all endogenous substances themselves:

--Omega-3 fatty acids from fish oil
--Vitamin D
--l-arginine
--Niacin (vitamin B3)

Many of the other substances, though not directly relevant to our plaque-control efforts, but are among the most effective nutritional supplements, also supplement endogenous levels: calcium pyruvate, creatine, acetylcarnitine, DHEA, testosterone, progesterone, growth hormone, pregnenolone, phenylalanine, tyrosine, melatonin, etc.

Curiously, most drugs are not meant to directly supplement endogenous levels, but are designed either to enhance or block an enzyme (e.g., acetylcholinesterase inhibitors that block breakdown of acetylcholine; HMG CoA reductase inhibitors to block cholesterol synthesis; angiotensin converting enzyme inhibitors to reduce blood pressure), to exert toxic effects on an organism (antibiotics, antivirals), or to exert an entirely unique effect that does not ordinarily occur in the human body (some anti-cancer drugs, for instance). (This is an admitted, vast over-simplification.)

That's not to say that any endogenous substance is desirable or safe when supplemented. Cortisol, thyroid hormone, and estrogens are three examples of endogenous substances that have downsides when administered at slightly more than physiologic concentrations.

Nonetheless, it makes me wonder if the world of endogenous substance supplementation has not been fully explored. Are there other endogenous substances that are as potent and wonderful, for instance, as vitamin D but not yet fully appreciated? I'm sure there are.

Wheat belly

You've heard of "beer bellies," the protuberant, sagging abdomen of someone who drinks excessive quantities of beer.

How about "wheat belly"?

That's the same protuberant, sagging abdomen that develops when you overindulge in processed wheat products like pretzels, crackers, breads, waffles, pancakes, breakfast cereals and pasta.



(By the way, this image, borrowed from the wonderful people at Wikipedia, is that of a teenager, who supplied a photo of himself.)

It represents the excessive visceral fat that laces the intestines and triggers a drop in HDL, rise in triglycerides, inflames small LDL particles, C-reactive protein, raises blood sugar, raises blood pressure, creates poor insulin responsiveness, etc.

How common is it? Just look around you and you'll quickly recognize it in dozens or hundreds of people in the next few minutes. It's everywhere.

Wheat bellies are created and propagated by the sea of mis-information that is delivered to your door every day by food manufacturers. It's the same campaign of mis-information that caused the wife of a patient of mine who was in the hospital (one of my rare hospitalizations) to balk in disbelief when I told her that her husband's 18 lb weight gain over the past 6 months was due to the Shredded Wheat Cereal for breakfast, turkey sandwiches for lunch, and whole wheat pasta for dinner.

"But that's what they told us to eat after Dan left the hospital after his last stent!"

Dan, aase examples of how vitamin D not just prevents disease, but seems to have a treatment effect. He also stresses three other things I've written about before, acid base balance, magnesium and potassium. If you can't get eat enough fruits and green leafy vegetables to obtain your potassium and magnesium and to get rid of low-grade chronic metabolic acidosis, then you should consider magnesium supplements and potassium bicarbonate supplements.

With these four experts and with this month's vitamin D news articles about breast cancer, brain function, artery blockage in the legs, soft skulls in babies, peripheral neuropathy in diabetics, childhood type-1 diabetes, colon cancer, and stress fractures and with the increasing number of scientists around the world jumping on the vitamin D express, why doesn't the government do something? What will it take? Like Carole says it will take a grassroots effort.

The first thing to do is tell your family and friends about vitamin D. Tell your doctor. Get your family's 25(OH)D tested, including your children. Once people begin to see it works, they will get their family and friends to take it. They will feel better and then the word will spread. All the government can do is make vitamin D illegal or limit the amount in each pill. The first is unlikely but not the second. With 5,000 IU capsules widely available, many people give no thought to taking one a day. But if the government limits the sale of anything over 400 IU and people had to take 12 of the 400 IU tablets, instead of one of the 5,000 IU, they might balk at so many pills. Before our officials in Washington take such a step, let's hope they read the Washington Post.

Biggest bang for your nutritional buck

Judging by the conversations here, in the Track Your Plaque Forums, and elsewhere, it's clear that many people are searching for the perfect diet.

Should we reconsider the role of saturated fat? Are there fractions of fatty acids in saturated fat that are more or less harmful? How about the role of fats on cancer risk? How about the role of proteins like casein on cancer risk? Are there flavonoid sources, or combinations of flavonoids, that yield outsized health benefits? Is there a ceiling for omega-3 fatty acid supplementation? Is there a role for linolenic acid sources in cardiovascular disease prevention? And on and on.

All important issues, to be sure, ones that we've all zig-zagged through over the past 30 years.

I also see patients every day, however, who are not interested in micro-managing their diet. Their goals are less ambitious: lose 20 lbs, feel good, raise HDL, reduce triglycerides and small LDL, all while meeting all the other responsibilities in their lives, like children, spouses, maintaining a household and jobs.

So, if your interest is not to consider whether we should distinguish myristic acid sources from palmitic, or if epigallocatechin is better when combined with quercetin, then the biggest bang from your nutritional buck can come from one single strategy:

Eliminate wheat flour products

Secondarily, avoiding corn starch products and "goodies" (candy, fruit juices, fruit drinks, cookies, potato chips, etc.--you know what they are) is important, as well.

It means weighing your diet more heavily in favor of vegetables and fruits; lean meats; healthy oils; and raw nuts and seeds, all in unlimited quantities. Dairy products should be limited, however, because of sugar effects.

Of course, this advice clearly contradicts the pronouncements of the USDA Food Pyramid (6-8 servings of grains per day), the American Heart Association, and the diabetes-causing American Diabetes Association diabetic diets.

But, follow this approach, a diet strategy that appears too simple to be effective, and the majority of people lose dramatic amounts of weight, raise HDL, reduce triglycerides, reduce small LDL, reduce C-reactive protein and other inflammatory measures, reduce blood pressure, and raise self-esteem.

It's also a lot easier than it sounds (after habits are broken) because the appetite stimulating effect of wheat is removed. Many, if not most, people also experience increased energy, including elimination of the afternoon "slump," improved sleep, less mood swings, less intestinal problems.

It may not be perfect, but if your interest is to get the most with a modest amount of effort, it works like a charm for the majority of people.

Can skinny be fat?

You're going to hate this.

Dr. Romero-Corral and colleagues from the Mayo Clinic presented an analysis of the National Institutes of Health-funded National Health and Nutrition Examination Survey (NHANES-3) at the recent American College of Cardiology meetings. (Science Daily also has some coverage on this report.)

Their analysis identified 2127 adults from the NHANES database who had normal body-mass indexes (BMI) between 18.5 and 24.9 units), average age 41 years old. When broken down by percent body fat (measured with bioimpedance, meaning a small electrical current is passed through the body, much like what the store-bought Tanita devices do), with normal-weight obesity defined as >20% body fat in males, >30% body fat in females, 55% of participants met criteria for designation as normal-weight obesity.

Compared to people with similar BMI's but who fell below these body fat percentage cut-offs, the normal-weight obese men had increased ratios of Apo B to Apo A1; were much more likely to have increased blood sugars or be diabetic; have higher C-reactive protein (CRP); were several-fold more likely to meet other criteria for diagnosis of metabolic syndrome; had lower HDL cholesterols; and had higher blood pressure. Women with normal-weight obesity were four-fold more likely to have coronary disease.

While preliminary, this suggests that a substantial number of people with apparently favorable body weights and BMIs are, in actuality, overweight when judged by metabolic parameters. This then probably leads to increased risk for heart disease. We can then fairly readily extrapolate the argument that a reduction in weight to even lower BMIs likely reduces or corrects these patterns.

This argument is similar to that proposed by several others, arguing that BMI is a flawed measure, since it does not incorporate muscle mass or skeletal factors ("big- or small-boned"). Instead, they have argued that waist circumference is preferable.

The normal-weight obesity syndrome was originally identified by Dr. Antonio de Lorenzo and colleagues at the University of Tor Vergata, Rome, Italy, and reported in Normal weight obese (NWO) women: an evaluation of a candidate new syndrome. Their studies of women with this "syndrome" have suggested that heightened measures of inflammation are present despite apparently normal body weight and BMIs. One such report, Normal-weight obese syndrome: early inflammation?, is available in full-text.

Is there a lesson to be learned for the Track Your Plaque program? I believe there is. I believe it means that, if you have any weight-sensitive parameter, such as low HDL, small LDL, high triglycerides, high CRP, high blood sugar, high blood pressure, etc., then further weight loss might be considered, even if BMI is around 25. Obviously, there is a rational limit to how far you can push this concept. (Anorexia is not good for you either.)

I find this a useful concept. It provides yet another potential strategy to pursue when the above patterns are encountered. Perhaps it's also a way to cap reliance on niacin, whose effects closely mimic that of weight loss.

Now that's a lot more preferable to more and more statin drug, isn't it?

Fatal underdose

Since vitamin D has been the topic of a fair amount of media coverage, I've received many questions about this fascinating "nutrient." A day doesn't go by without several nurses, friends, even fellow physicians stopping me to ask about vitamin D.

When I inform them that the average dose for females in this region (upper Midwest) is 4000-5000 units per day, 5000-6000 units per day for males, they are all surprised. "Then why did they say just take your multivitamin every day, or just drink your milk on the news?"

Many people are even more surprised, sometimes completely turned off, when they hear that, to be truly confident of adequate vitamin D dosing, a blood level of 25(OH) vitamin D3 needs to be checked. Now we're talking real hassle!

But there is no other way to do it. In order to obtain the full potential benefits of vitamin D, such as reduction in blood sugar and sensitization to insulin, reduction in cancer risk (especially prostate, colon, and breast), reductions in blood pressure, increased bone density, not to mention markedly increasing the likelihood of stopping or reducing your heart scan score, then achieving a desirable blood level of 25(OH) vitamin D is necessary.

Checking a blood level of vitamin D is no more difficult than having a cholesterol test, unless, of course, your doctor balks at the idea. (Time for a new doctor if that occurs.)

All too often, someone will be convinced they are taking a sufficient dose of vitamin D of, say 2000 units per day, only to discover that their blood level of 25(OH) vitamin D is something like 17 ng/ml--severe deficiency, sufficient to leave them exposed to all the undesirable consequences of vitamin D deficiency. Even though 2000 units per day represents 500% of the Institute of Medicine's recommended Adequate Intake for adults, to those familiar with the Track Your Plaque program it likely sounds like a child's dose.

Many variables enter into the equation in your body that determines your need for vitamin D: body size (heavier or larger people need more, with obese people often requiring enormous doses); sex (men need more than women); age (aging results in dramatic loss of ability to activate vitamin D in the skin); race; skin color (darker skinned people require more). Trying to guess your need is a fool's game. It's also a game that can seriously compromise your health and your hopes of ever stopping or reducing your heart scan score.



The message is clear: You cannot guess what your vitamin D need is. You cannot properly judge your vitamin D requirement by your age, body size, sex, or any other characteristic. Having a tan or a lack of a tan is a lousy indicator, as well. A simple blood level of 25(OH) vitamin D is an absolute necessity to gauge your vitamin D status, both before starting and while on your supplement.

Members of Track Your Plaque: Watch for the 30-some page booklet, The Track Your Plaque Complete Handbook on Vitamin D and Heart Health, which will be released in the next day or two.

Is direct-to-consumer drug marketing a failure?

According to the poll just completed by 80 participants on The Heart Scan Blog, 50% of respondents said they were less likely to take a drug after viewing an advertisement for it. A whopping 3 (4%) said that they would be more likely to take the drug after viewing an advertisement.

I find that interesting. If half the people responding are less likely to become customers of a drug company, then how does the drug industry justify running around-the-clock, every-few-minute ads? Spending by the drug industry for direct-to-consumer (DTC) advertising has ballooned over the past few years, and is now well over $30 billion dollars per year.

Unfortunately, despite the views of the highly-educated, curious, think-for-yourself, health information-seeking sorts of people who read this blog, drug companies still come out on top by DTC advertising. Estimates vary, with a 2006 U.S. Government Accountability Office study reporting that, for every $1 DTC advertising, sales are increased by $2.20. A 2000 Harvard study showed a higher return of $4.40 for every advertising dollar spent.

I'm sure the drug companies themselves have a very tight accounting handle on their own set of figures. We may not be terribly fond of these people and their often suspect tactics, but they're not stupid. They are certainly not stupid when it comes to making money.

Interestingly, 80% of the funds spent on DTC advertising focus on the 20 or so most popular drugs, all of which are used for treatment of chronic conditions like high cholesterol and high blood pressure, markets that are large and long-term. It pays very little to advertise drugs that may serve small markets for a short period. The implicit message is that this is not at all about informing the public. It is about advertising to grow revenues and profits--pure and simple.

It makes me wonder what the results of our poll would have been had we conducted it in 2000 before many people hadn't yet been brought to the brink of vomiting from the endless onslaught of commercial after commercial, complete with smarmy spokespeople (a la Lipitor's Dr. Robert Jarvik). What will it show in two years? Will the broader public join the more informed people who read this blog and become increasingly inured to the hard sell tactics?

For further discussion of this topic, click here for a reprint of an August, 2007 New England Journal of Medicine study, A Decade of Direct-to-Consumer Advertising of Prescription Drugs provides background, along with commentary on the impact of DTC drug marketing since the FDA allowed it 10 years ago. (Because it is a study and not an editorial, the editors fall short of making any recommendations for improvement or calling for a moratorium.)

Cheerios and heart health



Anna responded to the Heart Scan Blog post, Can you say "sugar"? with the following wonderfully telling comment:

A measured bowl of Cheerios and a bit of milk (whole, because it's what I had), equal to 75 grams of carbohydrate, gave me the highest ever blood glucose reading from a food (not counting glucose solution from a Glucose Tolerance Test). I was attempting a "homemade" version of a 3 hr GTT before going to my doctor with my concerns about my BG.

My BG started to rise very fast within 15 minutes after eating the cereal, peaked at about 250 mg/dL at 45 minutes, then slowly dropped. By about 60-75 minutes, I experienced strong hunger and carb cravings as the BG began to slowly drop, and by about 2.5 hours after eating, my BG had suddenly dropped quite low (in the low 70s) and I had developed a nasty hypoglycemic feeling (shaky, irritable, craving sugary foods, headache, etc.).

It's hard for me to see "heart healthy" Cheerios (or any other highly processed breakfast cereal) as anything other than a bowl of pre-digested sugar that contributes to roller coaster blood glucose and insulin levels, which a great way to start anyone's day. Certainly, I don't do well with Cheerios because I clearly have a damaged glucose regulatory system (probably a diminished or absent first phase insulin response, but I can't imagine that it is doing any good for people with healthy glucose regulation, either.

I banned prepared cold cereals from our house. If my 9 yr old son gets cereal at all at home, it's whole groats (not even rolled or steel cut because those aren't truly "whole grain" anymore), soaked overnight in some water and a tsp of plain yogurt (soaking neutralizes phytates and reduces cooking time), then cooked about 8-10 minutes (water added as necessary). Sometimes I add a bit of quinoa or almond meal prior to soaking to boost the protein content a bit. I garnish with a pat of butter, some heavy cream, and a dusting of cinnamon. If I'm feeling *really* indulgent, I drizzle about 1 tsp of Grade B maple syrup on top (Grade B is stronger in flavor and so less can be used). I don't eat this cereal myself, and truthfully, I'd rather my son not, either, but he sometimes wants cereal. It's the least damaging compromise I can come up with that we can both live with.



I have also seen diabetic effects from Cheerios: rises in blood sugar, exagerration of small LDL, drops in HDL, rises in triglycerides. Yes, it may reduce LDL a small quantity, but so what?

The Cheerios "heart healthy" claim is based on a piece of research apparently performed by Dr. Donald Hunninghake at the University of Minnesota and reported in 1998:

A study conducted at the University of Minnesota Heart Disease Prevention Clinic and published as "Cholesterol-Lowering Benefits of a Whole Grain Oat Ready-to-Eat Cereal" in the May issue of the Nutrition in Clinical Care journal in 1998, showed that people can lower their blood cholesterol by an average of 3.8% over six weeks by enjoying 3 cups of cold cereal made with 100% whole grain oats everyday as part of the meals and snacks in a healthy lower-fat diet.

(Unfortunately, I could not locate the actual publication. It doesn't mean it doesn't exist; I just couldn't locate it. Perhaps it's in a small journal not entered into the online publication database.)

The purported effects of Cheerios should not be confused with that of actual, intact oat bran, as suggested by studies such as those of Brenda Davy et al, High-fiber oat cereal compared with wheat cereal consumption favorably alters LDL-cholesterol subclass and particle numbers in middle-aged and older men, in which significant reductions in LDL particle number and small LDL (NMR) were obtained. (This study was also supported by Quaker Oats.) Several studies have shown that oat bran does indeed reduce LDL cholesterol, sometimes as much as 30-50 mg/dl. Cheerios can not even come close to this.

If Cheerios were nothing more than finely pulverized oats, then perhaps it wouldn't be so bad. But add corn starch and sugar, and you have ingredients that have potential to distort LDL particle size and yield blood sugar-escalating effects like those described by Anna.

The gravity of perpetuating these myths is brought home by a testimonial posted on the website for Cheerios:

“I had unexpected open heart surgery a year ago. As I adopted heart health habits during my recovery, I realized that I should have been eating the Cheerios cereal I carried around in a plastic baggie so many years for my kids!”

The IF Life: Intermittent fasting

There's a wonderful blog called The IF Life: Intermittent Fasting and Instant Freedom. It is written by personal trainer (and apparently former corporate bigshot), Mike O'Donnell.

Mike has a great take on brief, intermittent fasting that I found helpful and I believe you will also.






Intermitent Fasting 101: How to Start, Part I

The biggest question people have is how to effectively use IF (intermittent fasting) to achieve their goals and maximum results. These results and goals can vary by each person with fat loss, muscle gain, better health, improved performance in your sport of choice and more. With that comes the individuality of what is a person’s insulin resistance, current body composition (bodyfat%), daily lifestyle, eating habits, macronutrient ratios (carbs/protein/fat), type of exercise program, frequency and volume of training, recovery demands, and so forth. You are unlikely to find 2 people with the same set of parameters and same exact responses to an IF protocol. What does this mean? Well just that we need to start with a basic IF program, and then learn how to monitor results and adjust as we go. Even down the road things will change as you will improve health, lower insulin resistance and maybe change performance and recovery needs. So nothing is ever just one set way. Life is dynamic (always changing and evolving) and so should be the way we see our own journey for health and fitness.

What is IF?

For those that may not be familiar to the term, intermittent fasting is just taking times of fast (no food) and working them into your lifestyle. This can be either daily or a couple times a week (will get into that more below). Benefits include improving insulin resistance (which you will hear alot about as being the #1 key marker in so many health factors including weight loss, muscle gain, performance, recovery, anti-ageing and disease prevention) and giving the body a chance to do some internal cleaning (or housework), which can lead to improved immune function and overall health. If you want to see studies of all the benefits of IF/CR, please the resources page.


How do I begin to IF?

Is there only one set way in which to do IF? No. I could easily come up with 10 different IF protocols based on 10 people’s individual’s needs, lifestyle, exercise, goal, macronutrient ratios, and so forth. We will keep it simple and give the 2 most frequent and basic options.

Daily Fasting: Typically done every day and only giving the person a smaller eating window in which to get their calories. (for example, a 18hr daily fast would mean someone would only eat every day between the hours of Noon and 6pm). You will see varying times from 15-19 hours for daily fasting.
Fasting 1-3x a week: This could also be called alternate day fasting/calorie restriction (for those doing it every other day). This is just fasting of usually longer periods 18-24 hours but only 1-3x a week. Many variations to play with here.
“But which one is better and how to I do it now if I want…….”. Whoa, slow down. I know many have questions but let’s still try to keep this simple for now and expand into more specifics later. So far many people have experimented with both types of IF and have seen great results. But you also have to take into account all the other variables such as what is the person eating in that window? Is is junk food? Is it low carb? How many times a week are they doing it? Are they overweight and wanting just fat loss? Are they lower bodyfat but looking for improved performance and health? How many times a week are they exercising? What kind are they doing and what intensity? The list can go on and on, but let’s start to analyze the 2 types of IF and let you decide which one best suits your lifestyle.

Daily Fasting (15-19 hours):

The Advantages are:

--simple eating strategies for every day
--even people that may not eat 100% clean foods can see weight loss due to the smaller window and lower calorie total per day


The Disadvantages are:

--Can possibly lower metabolism if calories are too low for too long (not what you want if your #1 goal is weight loss)
--Not getting enough food in the smaller window may also lead to muscle loss for more active people (not good)
Fasting 1-3x a week:


The advantages are:

--Allows a person to make sure they are getting enough calories on the non-fasting days, and then just keeps to a simple small feed window (if any) on the IF days.
--Simple thinking for people who do not have experience in how to eat clean to eat one day, and then eat in a smaller window the following day (alternate day fasting/CR). This can achieve fat loss for people who are mostly overweight and may not be too active. (of course don’t get me wrong, that eating healthy is our main goal but this can be a good step for some people to start their weight loss jounrey and learn how to make better choices as they go)


Disadvantages:

--Doesn’t force a person to make better choices with their food (as one could probably eat junk one day, and then fast the next and still lose weight). Not something we want long term because this is not going to improve your other health markers (diseases prevention, insulin resistance) like a good IF program on healthy foods.


Again I can’t say it enough, as there are so many variables to play with in an IF program. Some people may say “well it didn’t work for me” or “I didn’t gain any muscle”. Well unless I know everything about what you do for exercise daily, your total calories, when you eat and your macronutrient ratios (protein/carbs/fats), I can’t even begin to help. IF is a simple tool to start with, but you have to take full responsibility for your own health and progress and learn when it is not working and when to change things up! Like I said, if it is NOT working then stop IF and rethink your attack plan (or get a professional to coach you on it).

So to sum up, here are some examples of what you can play with:

Daily Fasting of 15-19 hours. I would highly suggest that if you do this make sure you are recovering from your exercise and start only Mon-Fri and give yourself the weekends to eat all day (hopefully with healthy choices of course)


Fast 1-2x a week to start if you have never done any fasting or do not know how to eat healthy and control your macronutrients. Start with 1-2 days a week with fasts of 18-20 hours (I wouldn’t start with 24 hr fasts to begin as most people can not handle the hunger cravings and in turn will just end up eating all the wrong foods when they do eat) and say eat only from say 1pm-6pm for example. Drink lots of water (add lemon, your liver will appreciate it! and it will help with the hunger). For example, fast Wed and Sun (or whatever days fit into your schedule)

Or you can do a mixed approach and fast every other day for a small eating window. For example eat all day Mon, only 12-6pm on Tues, all day Wed, 12-6pm on Thurs, etc. Start with bigger eating windows and make them smaller as you get used to fasting. This approach may work for people who have alot of weight to lose and can not (I should really say “will not” as everything is a choice!) eat 100% healthy for the moment. This approach may not work for more advanced people who have a high activity level unless you are getting a ton of health calories in that fasting window.
“So What Do I Eat on the Fasting Days?”

That’s the best part, you should be able to eat unlimited healthy foods (healthy proteins, fats, veggies, fruit, nuts…see Paleo Diet in the resources page). If you are eating more processed foods, breads and other high calorie intakes then you may have to monitor and control portions. Please know this is NOT about chronic calorie restriction or starving yourself. When I do weeks of eating 1-7pm, I am eating a ton of protein and veggies (complex carbs pwo also). I am hardly starving myself. I am not taking in 4000 cal a day however, so my daily average of say 2200-2500 cal is still low compared to the alternative. If you want to lose weight of course you will need a calorie deficit to pull the “stored energy” out of fat cells. That is the advantage to eating “Paleo”, you can’t over eat on protein, healthy fats, fruits (in moderation) and veggies. If you are making bad choices or starving yourself on IF, you may lose the effectiveness or slow progress. All goes back to the fact that if it is not working, then change something up! (there is always something that can be changed…and food choices is the #1 place to start!) I don’t count calories, and by eating natural foods that have been around for 100s of years….I don’t need to! (eating healthy natural foods will not only help you lose weight but also improve your health and lower your risks of diseases….so eating for health should always be the #1 goal in any program)

Hopefully this will give a good overview while trying to keep it simple. Remember it’s your journey to take, measure progress and adjust things that are not working. Start with one approach, and modify it. Who knows, your approach may change every couple months and that is ok. Life is always changing and so should your approach to health and fitness (as the body always responds better to change than sticking with the same eating/exercise approach for a long period of time).

Warfarin is scary stuff

Gilbert is a 58-year old high school science teacher.

When I first met Gil, he'd been having bouts of atrial fibrillation and had required various medications to suppress recurrences of the rhythm. However, because his rhythm proved somewhat difficult to control, his electrophysiologist (heart rhythm specialist) prescribed warfarin to reduce the risk of stroke. With atrial fibrillation, because of blood stagnation (in the left atrial appendage) in the heart, there is a stroke risk of approximately 8% per year. Warfarin reduces this risk substantially, to about 2%.

I met Gil because he had a cholesterol disorder. In my practice, the first step in gauging the implications of a lipid or lipoprotein disorder is to obtain a heart scan. If the heart scan score is zero, great. It means that we have plenty of time to treat the disorder since risk for cardiovascular events is near zero also; it means less intensive efforts less intensive efforts are necessary. But if the heart scan score is, say, 1200, then an aggressive approach in short order is required, since the risk for heart attack may as high as 20-25% per year, even in the absence of symptoms.

Gil's heart scan score: 787--high and posing a risk for heart attack of about 5-10% per year without preventive efforts. Gil did indeed prove to have a complex lipoprotein disorder, as well as high blood pressure, vitamin D deficiency, and several other potential contributors to coronary plaque.

Gil did just about everything right: He exercised, followed the recommended diet, achieved better than the Track Your Plaque 60-60-60, lost 18 lbs of abdominal fat.

Gil's rhythm stabilized for several months, only to have atrial fibrillation break through again. So Gil's electrophysiologist re-prescribed warfarin.

18 months later, Gil's 2nd heart scan score: 1410--a near doubling. Unsettling to Gil and to us, to say the least.

How can this happen in the face of perfect lipids/lipoproteins, correction of hidden causes like lipoprotein(a) and inflammation, along with a vigorous lifestyle effort?

I fear that the culprit might be warfarin.

Warfarin, better known by its brand name, Coumadin, may have some effects that intersect with the Track Your Plaque mission of reducing coronary plaque.

It is no secret that, beyond the obvious risk of bleeding from blood thinning, warfarin also may:

--Accelerate aortic valve calcification
--Accelerate calcification of the framework of the mitral valve (the mitral "anulus")
--Accelerate osteoporosis
--Induce an artificial situation of vitamins K1 and K2 deficiency.

The vitamin K1 deficiency is the route by which blood thinning is achieved. However, the K2 deficiency may have undesirable consequences, among which are the above list of various pathologic calcifications.

I therefore wonder if warfarin dramatically accelerated the coronary calcium that we track to gauge the progression of coronary atherosclerosis. One experience is hardly sufficient reason to sound the alarm. It is also difficult to pinpoint the cause of the explosive growth in Gil's coronary calcium specifically on warfarin.

That all said, I am quite certain it was the warfarin.

Unfortunately, some people are unavoidably committed to warfarin, such as those with specific genetic blood clotting disorders, prosthetic valves, prior deep vein thromboses and pulmonary emboli, etc.--serious reasons. Until an alternative emerges, warfarin remains a necessity for some people. (No, nattokinase is NOT an alternative, at least not one that would permit survival.)

My personal policy is that warfarin be used only when absolutely necessary and the gains markedly outweight the risks--including that of possible accelerated calcification of multiple sites.

Whether we will be able to get Gil off warfarin and potentially gain control over his coronary disease/plaque/calcium remains to be seen. I sure hope so.
