Calculus of the cardiologist

I call this the "calculus of the cardiologist":

Heart procedures = big money

More procedures = more big money

You do the math. If you do more procedures, you get more money.
What if your patients don't need more procedures? That's easy. You lower the bar on reasons to do procedures. You scare the pants off people and lead them to think that all heart disease or questions about heart disease are potentially life-threatening. You could even appear to be doing the patient a big favor. "My Lord! This is potentially dangerous. We need to perform a procedure without delay!"

There are incentives beyond direct cash payment. A patient of mine today showed me a memo to employees in his company that showed why certain hospitals are targeted for care. The criteria for choosing centers was based on number of procedures performed. In other words, the more procedures performed at a hospital, the more procedures will be directed there. Of course, this makes sense at some level. More procedures can also mean greater skill.

But have we lost sight of the fact that the mission is not more procedures and more money, but to get rid of a disease? If the intensity of effort devoted to heart procedures were re-directed to early detection, prevention, and reversal of disease, we'd have half the hospitals we now have. We'd also chop a huge chunk out of the national healthcare budget.

Lipoprotein(a) treatment alternatives

A question from a reader:


Two years ago, my doctor recommended a comprehensive lipid screening because both of my parents had heart disease. My only blood component way out of line was LP (a) [lipoprotein(a)]. It was 130. According to the lab that conducted the screening, Berkeley Heart Lab, a level above 30 should be cause for concern. I was stunned that mine was more than quadruple the danger level.

I began taking two grams [2000 mg] of niacin a day in addition to the Lipitor I was already taking. The next reading, a few months later, was 87. Over a period of about 18 months, I had a total of four readings from Berkley Heart Lab. My LP (a) fluctuated in the 80-130 range – still way above normal. My doctor said there was little else I could do to control it.

That doctor has since retired. I now see another doctor who uses a different lab. My first LP (a) reading with him a few months ago was 17, which is normal. I am still taking the same amount of niacin and Lipitor and I can’t think of anything that would account for the huge discrepancy. I’m going to have another test again soon.

Is one of the labs giving erroneous readings? If so, how can I tell which? If Berkeley Heart Lab is correct, is there anything I can do about my increased coronary risk due to high LP (a)?

Tom D.

Tom's frustration on the variation of Lp(a) is due to the fact that laboratories run the Lp(a) test by several different techniques and will generate tremendous variation in values. The key is to stick to the same measure over and over from the same lab, else you'll be terribly confused and frustrated. Tom essentially should ignore the value obtained that was unexpectedly low.

Another issue: Lp(a) is a turtle. It responds very slowly. In fact, we rarely check it more than once or twice a year. Check it too soon after a treatment change and it won't fully reflect the effect. You've got to wait at least several months before re-checking.

How about treatment alternatives? They are:

--More niacin. Not my favorite choice, since niacin >2000 mg per day begins to generate more side-effects, but it is a choice. You can go to 4000-5000 per day, but only with your doctor's supervision due to liver effects.

--Testosterone for males. We use topical testosterone from Women's International Pharmacy in Madison, Wisconson. Prescription patches like Testim are also effective.

--Estrogen for females. This is less "clean" than testosterone, introducing questions about endometrial and breast cancer risk, but it is a choice.

--DHEA--A small effect but every little bit can help. We use 25-50 mg per day, depending on blood levels and only if you're 45 years old or older.

--l-carnitine--In my experience, a small effect. It requires 2000 mg per day, which is expensive. Sometimes, an expected large effect develops, so it's worth a try if it fits in your budget.

--Fibrates--These are the drugs Tricor and Lopid. I don't like these agents very much because I think they're weak, including the effect on Lp(a) reduction. But they are choices for you and your doctor.

Lastly, you can simply be guided by your heart scan score. For example, if Tom's initial heart scan score is 200, and he continues his current program and one year later his score is 300, then alternative treatments are worth considering. But what if Tom's score is 189--he's regressed his coronary plaque. Then, who cares what his Lp(a) is?

Another issue to keep in mind is that, in the presence of Lp(a), keeping LDL to very low numbers (e.g., 60 mg/dl) may added value in preventing coronary plaque growth.

Trapped in a low-fat world

If you would like to...

--Reduce (good) HDL

--Raise triglycerides, sometimes by hundreds of points

--Raise blood sugar into the pre-diabetic range

--Raise blood pressure

--Accelerate coronary plaque growth

then go on a low-fat diet like the one promoted by long-time super low-fat advocate, Dr. Dean Ornish. Every day I have to educate patients that a low-fat diet as advocated by Dr. Ornish is a destructive, counter-productive process that makes coronary plaque grow and increases your heart scan score.

If you want to gain control over coronary plaque, do not follow the Ornish program or anything resembling it. The Ornish program is a dead end.

Instead, the crucial components of a healthy diet for plaque control are:

--Low saturated and hydrogenated fat, but not low all fats.

--High monounsaturated and omega-3 fats

--Low glycemic index (i.e., slow sugar release)

--High fiber

That simple. An excellent program to put these limits to practical use is the South Beach Diet. Or, follow the more detailed guidelines on the Track Your Plaque website (open content section).

Blame the niacin

Despite the fact that niacin is:

1) A vitamin--vitamin B3

2) One of the oldest cholesterol-reducing agents around with a long-standing track record of effectiveness and safety

3) Available as a prescription drug as well as a variety of "nutritional supplements"

most physicians remains shockingly unaware of its benefits, effects, and side-effects. Most, in fact, are either ignorant or frightened of advising their patients on niacin use. As a result, I commonly have to tell my patients to resume the niacin that their primary care physician has (wrongly) stopped because of itchy feet, grumpiness, groin rash, urinary tract infections, nightmares, diarrhea, hair loss, runny nose, etc. All of these are REAL reasons doctors have advised patients to stop niacin (though none were actually due to niacin).

Is niacin really that troublesome? No, it's not. In fact, if used properly, it's among the most effective and safe tools available for correction of low HDL, small LDL and other triglyceride-containing lipoproteins, lipoprotein(a), and dramatic reduction of heart attack risk. If added to a statin agent, the heart attack risk reduction can approach 90%.

Statins are just too easy for doctors to prescribe. Niacin, on the other hand, requires a good 15-20 minutes to describe how to use it. It could generate an occasional phone call from a patient who struggles with the annoying but largely harmless and temporary "hot-flush" feeling, a lot like a hot blush. Given a choice, most doctors would simply choose not to be bothered. For this reason, I'll commonly see many, many people with uncorrected low HDLs and other patterns.

Have a serious discussion and press for confident answers if you find your doctor reflexively telling you that the wart on your thumb should be blamed on niacin.

Here are the steps we advise that really make taking niacin easy and tolerable:

1) Take with dinner.

2) Take with 2 extra glasses of water. If you experience the hot-flush later on, drink an additional 2 8-12 oz glasses of water i.e., a total of 16-24 oz). Extra hydration is extremely effective for blocking the hot-flush.

3) Take a 325 mg, uncoated aspirin. This is only necessary in the beginning or with any increase in dose, rarely chronically for any length of time.


This is not to say that there aren't occasional people who are truly and genuinely intolerant to niacin. It does happen. But those people are a small minority, less than 5% of people in my experience. Niacin is far more effective and safe than most physicians would have you believe.

Eat fish three times a day

Patients commonly ask, "Why can't I get vitamin D from food? I drink milk and eat fish."

They're absolutely right: both vitamin D and some oily fish contain vitamin D. However, it's a matter of quantity. An 8 oz. glass of milk contains 100 units of vitamin D (at least it's supposed to; this is not always true). A serving of oily fish like salmon or herring may contain up to 400 units. Thus, if you ate fish three times a day like the Eskimos or the Inuit, you might obtain sufficient vitamin D to prevent the broad and alarming spectrum of phenomena associated with deficiency.

I suspect that most people don't want to eat fish three times a day, nor drink the 20 to 50 glasses of milk per day that would be required to obtain a truly healthy quantity of vitamin D.

The vocal and outspoken Dr. John Cannell of the Vitamin D Council (www.vitamindcouncil.com) has written eloquently on the potential relationship between influenza and vitamin D deficiency. He and his co-authors on a recently published paper point out that the peculiar and unexplained seasonality of influenza corresponds to vitamin D levels. Read his eloquent discussion in Medical News Today at http://www.medicalnewstoday.com/medicalnews.php?newsid=51913.

In the article, Dr. Cannell explains:

"The vitamin D steroid hormone system has always had its origins in the skin, not in the mouth. Until quite recently, when dermatologists and governments began warning us about the dangers of sunlight, humans made enormous quantities of vitamin D where humans have always made it, where naked skin meets the ultraviolet B radiation of sunlight.
We just cannot get adequate amounts of vitamin D from our diet. If we don't expose ourselves to ultraviolet light, we must get vitamin D from dietary supplements...Today, most humans only make about a thousand units of vitamin D a day from sun exposure; many people, such as the elderly or African Americans, make much less than that. How much did humans normally make? A single, twenty-minute, full body exposure to summer sun will trigger the delivery of 20,000 units of vitamin D into the circulation of most people within 48 hours. Twenty thousand units, that's the single most important fact about vitamin D. Compare that to the 100 units you get from a glass of milk, or the several hundred daily units the U.S. government recommend as “Adequate Intake.” It's what we call an “order of magnitude” difference.

"Humans evolved naked in sub-equatorial Africa, where the sun shines directly overhead much of the year and where our species must have obtained tens of thousands of units of vitamin D every day, in spite of our skin developing heavy melanin concentrations (racial pigmentation) for protecting the deeper layers of the skin. Even after humans migrated to temperate latitudes, where our skin rapidly lightened to allow for more rapid vitamin D production, humans worked outdoors. However, in the last three hundred years, we began to work indoors; in the last one hundred years, we began to travel inside cars; in the last several decades, we began to lather on sunblock and consciously avoid sunlight. All of these things lower vitamin D blood levels. The inescapable conclusion is that vitamin D levels in modern humans are not just low - they are aberrantly low."


Like Dr. Cannell, I am absolutely convinced that vitamin D deficiency plays an important role in a number of illnesses, including coronary disease. The more we mind our patients/participants vitamin D status (blood levels of 25-OH-vitamin D3), the more easily we gain control over LDL cholesterol, pre-diabetic patterns, blood pressure, blood sugar, and coronary plaque. In fact, I am becoming rapidly convinced that vitamin D deficiency is an extremely important coronary risk factor.

Because I live in Wisconsin (bbrrrrr!) where seeing the sun is a cause for celebration and sun exposure is possible three months a year, I take 6000 units per day vitamin D. This is the amount necessary to raise my blood levels into the true, physiologic range of 50-70 ng/ml. My wife takes 2000 units per day, and each of my kids takes 1000 units per day, though I believe that my 14-year old son (my size now) should take more. We'll judge by blood levels.

If there is a little-known secret to reducing heart scan scores, vitamin D is that "secret".

What if I had a cure for coronary disease?

If I had a cure for coronary disease, what would it look like? What would constitute cure? Would you recognize it if I showed it to you?

In the strictest sense, "cure" means an absolute elimination of any sign of coronary plaque, as well as elimination of any and all dangers associated with coronary disease. It would also mean elimination of the factors that created coronary atherosclerotic plaque in the first place.

In a more practical sense, you could argue that "cure" means a reduction of the amount of material that constitute coronary disease along with a dramatic reduction of the associated risks (i.e., heart attack).

You might call this second, more lax definition "regression" or "reversal".

Is "cure" in the strictest sense possible? No, not to my knowledge in 2006. Yes, there are many (kooks) who claim this is possible, but there's no objective evidence of this occurring.

Regression, or reversal, however, is indeed possible. In fact, I've seen it countless times following the participants in the Track Your Plaque program. If your heart scan score goes from 1000 (a bad score with high risk for heart attack) to 750, you've experienced a large reduction in the amount of atherosclerotic plaque that is behind coronary disease. You've also reduced your risk of an "event" like heart attack to near zero (provided you remain on the program that achieved regression in the first place).

Unfortunately, with present technology regression or reversal does not mean that the original causes of coornary plaque are eliminated. They're just controlled. Fish oil, for example, powerfully reduces triglyceride-containing lipoproteins that trigger coronary plaque growth. But if you stop fish oil, the evil lipoproteins come right back and start injuring your coronaries, causing more plaque growth.

The Track Your Plaque program is the closest thing I know of to a "cure" for coronary disease, that is, "cure" in the sense of regression or reversal. Perhaps in future we'll have a "cure" in the strict sense. Until now, this program is the best there is.

Alternatives to fish oil capsules

Occasionally, someone will be unable to take fish oil due to the large capsule size, excessive fishy belching, or stomach upset. The easiest solution is usually just to try a different brand, e.g., Sam's Club (Makers' Mark brand) enteric-coated.

However, sometimes liquid fish oil preparations may be preferred. Here'a list of products we've used successfully. All cost more than plain old fish oil capsules, but fish oil is so crucial to your heart scan/coronary plaque control efforts, that it really pays to search out alternatives.



Liquid fish oil alternatives to capsules:

Liquid fish oil--e.g., Carlson's liquid fish oil. Most liquid fish oil comes flavored either lemon or orange.



Frutol--A very clever re-formulation of fish oil that makes it water-soluble and non-oily. The Pharmax company has put their fish oil into a fruit flavored base that tastes pretty good and is not too expensive.
Go to www.pharmaxllx.com for more information. Unfortunately, I do not believe it's available in stores.





Coromega--another non-oily preparation, though available in some health food stores. Coromega comes in little single-serving foil dispensers. It tastes kind of fruity (though I personally like the Frutol better for taste and consistency). It's kind of pricey ($1.40 per day for two packets).



Regardless of what preparation you choose, you can determine the dose needed by adding up the EPA+DHA content. For the basic prevention effect, the starting dose for the Track Your Plaque program, you need a total of 1200 mg per day of EPA+DHA. Higher doses, e.g., 1800-2400 mg per day, may be required for correction of high triglyceres or postprandial (after-eating) abnormalities.

Ignoring your heart scan is medical negligence

I continue to be dumbfounded that many doctors continue to pooh-pooh or ignore CT heart scans when people get them.

I can't count the number of people I've seen or talked to through the Track Your Plaque program who've been told to ignore their heart scan scores. The most extreme example was a man whose physician told him his heart scan score of nearly 4000 was nothing to worry about!


A real-life story of a retired public defense attorney whose heart scan score of 1200 was ignored, followed two years later by sudden unstable heart symptoms and urgent bypass prompted us to write this fictitious lawsuit. Though it's not real, it could easily become real. To our knowledge, no single act of ignorance about heart scans has yet prompted such a lawsuit, but it's bound to happen given the number of scans being performed every year and the continued stubbornness of many physicians to acknowledge their importance.



Major Malpractice Class Action Lawsuit Looms for Doctors Who Ignore Heart Scan Tests

It's been several years since new medical discoveries have debunked old theories regarding heart disease and heart attack and have verified the efficacy of CT heart scans for detecting both early and advanced heart disease. Doctors who fail to keep apprised of these finding or refuse to change their practice for financial reasons put themselves at risk for becoming defendants in a major malpractice class action lawsuit. The plaintiffs will be a growing class of persons who were debilitated by avoidable heart attacks and heart procedures and the heirs and estates of those who have died.
Milwaukee , WI (PRWEB) November 29, 2005 -- This press release outlines a template for a potential class action lawsuit that may be on the horizon for the medical industry. The class of plaintiffs for this theoretical action remains latent but is growing on a daily basis. However, it requires only one such plaintiff to find an attorney who recognizes the scale and magnitude of the potential damages and move forward on a contingency basis. In real terms, this class could include 80% of those who had a heart attack, underwent a heart procedure, or subsequently died. According to the latest American Heart Association statistics, this number is estimated to be a least 865,000 persons and the entire class could easily be 10 times that number. Using a conservative estimate of $500,000 in damages per class member, the total damages could exceed $400 billion.

The plaintiffs, defendants, third parties, and facts surrounding the following moot complaint represent an actual incident. The names, specific health information, and dates have been changed to protect potential litigants.

Plaintiff, through his attorneys, brings this action on behalf of himself and all others similarly situated, and on personal knowledge as to himself and his activities, and on information and belief as to all other matters, based on investigation conducted by counsel, hereby alleges as follows:

NATURE OF THE ACTION

1.Plaintiff brings this class action on behalf of himself and all other persons who suffered physical damages or mental distress as a result of receiving a medical diagnosis indicating they had no identifiable heart disease, elevated risk for heat attack, or who were prescribed medications not suited to treat their heart disease once detected.

2.Substantial and irrefutable medical evidence has established that cardiac stress testing is an ineffective method for detecting heart disease of the type that is the root cause in over 90% of all heart attacks and other complications of heart disease that result in death or debilitating injury. A readily available and well-publicized test known as “CT heart scanning” is capable of detecting virtually all heart disease of this nature. It has also been established that simple cholesterol testing often fails to detect persons like likely to develop serious heart disease and prevents them from receiving common treatments capable of reducing or eliminating the source of their undetected heart disease. Readily available blood testing techniques exist that are capable of detecting non-cholesterol related sources of heart disease.

3.The medical community has made significant investments in outdated methods of detecting and treating heart disease. They rely on the revenue streams generated by providing these treatments to persons whose heart disease has progressed to the stage that intervention is required to prevent death or debilitation. Any change in diagnostic or treatment methods resulting in the prevention of heart disease would require substantial investments in new technologies and would severely reduce the market for current treatments. Plaintiffs believe this is a motivating factor in the neglect and willful suppression of readily available technology capable of detecting and preventing heart disease and represents gross medical malpractice.

SUBSTANTIVE ALLEGATIONS

On January 23, 1999, Plaintiff underwent a CT Heart Scan which was interpreted by a cardiologist at the ABC Scan Center . Plaintiff received a report from the Scan Center cardiologist indicating that his “calcium score” placed him in the top 1% for heart attack risk among men in his age group. The report also included the comment “Patient has a high risk of having at least one major stenosis (50% or greater blockage) in his Left Anterior Descending (LAD) artery and is urged to consult with a physician regarding this finding.”

On March 3, 1999 Plaintiff presented Defendant with the results of the January 23, 1999 CT Heart Scan. Defendant told Plaintiff to disregard the CT Heart Scan Results and ordered a physical including a stress test and cholesterol blood test.

On April 1, 2005, Plaintiff had a heart attack and a subsequent coronary angiography that confirmed multiple obstructive coronary plaques in his LAD. Plaintiff received an emergency balloon angioplasty to relieve his acute condition. Substantial damage to plaintiff's heart was incurred before emergency angioplasty could be instituted.

On April 3, 2005, per Defendant's recommendation, Plaintiff underwent open heart surgery to insert three bypasses in his LAD to resolve substantial obstructive heart disease, the same artery identified as having likely obstructive heart disease over 5 years earlier via CT heart scan.

On July 7, 2005, Plaintiff independently obtained additional blood testing not ordered by Plaintiff and was found to have several additional blood abnormalities not discovered by Defendant that are known to contribute to the development of heart disease and were readily treatable using lifestyle changes, nutritional supplements, and prescription drugs.

As early as September, 1996, the American Heart Association (AHA) issued a “Scientific Statement” to health professionals acknowledging the strong link between heart attacks and high calcium scores in asymptomatic patients. Extensive studies and references have confirmed the ineffectiveness of stress testing to reveal early heart disease in asymptomatic patients.

Plaintiff alleges that Defendant failed to utilize readily available medical tests and protocols to identify, aggressively treat, and potentially delay, halt, or reverse advanced heart disease that later resulted in extensive physical and emotional trauma to the Defendant.

PRAYER FOR RELIEF

WHEREFORE, Plaintiff herein demands judgment:

A. Declaring this action to be a proper class action maintainable pursuant to Rule 23 of the Federal Rules of Civil Procedure and declaring Plaintiff to be a proper Class representative;

B. Awarding damages against each defendant, joint and severally, and in favor of Plaintiff and all other members of the Class, in an amount determined to have been sustained by them, awarding money damages as appropriate, plus pre-judgment interest;

C. Awarding Plaintiff and the Class the costs and other disbursements of this suit, including without limitation, reasonable fees for attorneys, accountants, experts; and

JURY DEMAND

Plaintiff hereby demands a trial by jury.

Light the fuse of heart disease

Father Bob, despite his calling as a priest and counselor, led a stressful life. His average day was packed tightly with commitments: counseling members of his congregation, visiting the hospital, more official priest and church duties.

At age 53, his heart scan score of 799 came as a complete surprise. Even more of a surprise, his stress test was dramatically abnormal showing poor flow in the front of his heart at a level of exercise that wouldn't challenge most 75 year olds. His blood pressure with exericse: 230/100. Bob was shocked.

A few stents to the LDL later, Bob was trying to turn a new leaf on lifestyle. His life prior to the diagnosis of heart disease was driven by convenience. Because his day was so filled with commitments, he simply grabbed what he could from hospital cafeterias, fast foods, etc.

But after his procedure, Bob committed to choosing healthier foods, walk every day, and resist the food temptations presented by convenience.

However, temptation defeated him twice in the first few weeks after his stents. On the first occasion, Bob gave into eating a cheeseburger. On the second, Bob was at a fish fry (this is Wisconsin, after all) and ate a large serving of deep-fried fish.

On both occasions, Bob started feeling awful within minutes after eating: foggy, bloated, gassy, and fatigued. He took his blood pressure after each incident: 210/90, even though his blood pressure had more recently been trending down towards 130/80.

What happened? Grotesquely unhealthy foods like the deep-fried fish and cheeseburger provoke an abnormal constrictive process body wide. Some call this "endothelial dysfunction". Regardless, it is a graphic and frightening demonstration of the power of these sorts of unhealthy foods to wreak immediate and dangerous effects. Father Bob's response was more exagerrated than most, but it happens to all of us.

Eat badly and your body will pay the price. Even that occasional hot chocolate sundae or Egg McMuffin will yield cumulative injury, among which will be a rise in your heart scan score.

"I don't know what I'm doing here"

Jim came to the office at the prompting of his wife.

At age 52, Jim was semi-retired, having to work only a few hours a week to maintain his business. He'd had a high cholesterol identified about 10 years earlier and had been taking one or another statin drug ever since.

However, Jim's wife was a pretty savvy girl and understood the inadequacies of the conventional approach to heart disease prevention. Nonetheless, when Jim came in, he declared, "I feel great. I don't know what I'm doing here!"

I persuaded Jim to undergo a heart scan. His score: 2211, in the 99th percentile (the worst 1% for men in his age group). However, it was worse than that. Any score above 1000 carries a heart attack risk of 25% per year unless prevention issues are fully addressed.

Indeed, Jim proved to have far more than a high LDL cholesterol. Among the patterns uncovered with his lipoprotein analysis were small LDL, the postprandial (after-eating) abnormality of intermediate-density lipoprotein (IDL), and high triglycerides and VLDL. All would require correction if Jim is to hope to gain control of his extensive coronary plaque.

The message: Trying to discern risk for heart disease from cholesterol is complete folly. This man was going to die or have an urgent major heart procedure within the next year or two, all while taking his statin drug.

Discard the silly notion that cholesterol tells you everything you need to know about heart attack risk. It does not. It helps a little but leaves vast voids in risk determination. Fill those gaps with a heart scan, plain and simple.

Family lessons

Lou was recovering from his 3rd bypass operation. This third go-round left him weaker, slower, less quick on the rebound. In fact, he was lucky to have survived.

At 71 years old, Lou went a good 15 years since his second bypass, another 10 years prior to his first bypass at age 46.

In the days immediately following Lou's bypass, I had a chance to talk to his son, who stayed at his Dad's bedside while Lou struggled through post-op recovery.

"Did your Dad tell you about why this has happened, what caused his heart disease?" I asked.

"Sort of. He just said I should get checked," Lou's son, Aaron, replied.

"Did he mention the lipoprotein(a) pattern he has?"

"No. He never mentioned anything like that. He just said to get checked."

That's how it gets played out more often than not: Mom or Dad has a heart attack, stents, or (3rd) bypass, the children are told to get checked. Getting "checked" assumes that the doctor knows what to check for.

In Lou's case, the reason why he was in the hospital getting his 3rd (and final) bypass was lipoprotein(a), along with genetically-determined small LDL particles, low HDL, a postprandial (after-eating) disorder, hypertension, and borderline diabetes, not to mention vitamin D deficiency, omega-3 fatty acid deficiency, and marginal thyroid function. (Lou, a retired city employee, had showed only marginal interest in correcting these patterns. While he accepted medications, he proved unwilling to engage in the diet and nutritional supplement strategies required to correct his patterns.)

So Lou's 3rd bypass operation provided a moment of reflection for Aaron to ask: "Could I share the fate of my Dad?" With Lou's combination of genetic patterns, there was at least a 75% likelihood that he did. Sadly, going to his doctor would likely yield little more than a cholesterol panel, a question about smoking, and a prescription for Lipitor.

Just getting "checked" would be, more than likely, a recipe for disaster for Aaron: heart disease in his 40s or 50s. That's why you need to take control over this sad state of affairs and ask--no, insist--that an effort be made to determine whether you might share your parents' fate.

Look like Jimmy Stewart


"This diet works great," Don declared. "But I think I've lost too much weight."

At 67 years old and 5 ft. 11 inches, Don began the program weighing 228 lbs (BMI 31.9). Because of high triglycerides, high blood sugar, high c-reactive protein, and excessive small LDL, I instructed Don to eliminate all wheat products from his diet, along with cornstarch and sweets. His intake of lean meats, eggs, vegetables, oils, raw nuts, etc. was unlimited.

Don now weighed 194 lbs, down 34 lbs over 6 months (BMI 27.1). Triglycerides, blood sugar, blood pressure, and well-being had improved dramatically; small LDL, however, had dropped only 30%--still room for improvement.

"My friends say I'm too skinny. They ask if I have cancer!"

I've heard this many times: Someone loses weight in a relatively short period of time and friends and family tell you you're too skinny. "It must be cancer. Nobody loses weight like that."

Unfortunately, many Americans have forgotten what normal looks like. Normal is certainly not a 190-lb, 5 ft 4 in woman, nor is it a 228 lb, 5 ft 11 inch man. But Americans have put on so much weight that the prevailing view of what constitutes "normal" weight has been revised upward. Normal is closer to what we see in old movies from the 1940s and '50s with people like Jimmy Stewart and Donna Reed. That's what we are supposed to look like.

So Don actually remains mildly overweight but is judged as "too skinny," or even cancer-ridden, by friends and family.

Ignore such comments. As you lose pounds and approach a truly desirable weight, realize that you are returning to the normal state, not the vision of "normal" now held by most Americans.

Getting vitamin D right

Vitamin D is, without a doubt, the most incredible "vitamin"/prohormone/neurosteroid I have ever encountered. Frankly, I don't know how we got anything accomplished in health pre-D.

Unfortunately, people I meet rarely take their vitamin D in a way that accomplishes full restoration of vitamin D blood levels. It really isn't that tough.

Here's a list of common tripping points with vitamin D:

"I take vitamin D: 1000 units a day."
This is probably the most common mistake I see: Taking a dose that is unlikely to yield a desirable blood level. (We use 60-70 ng/ml of 25-hydroxy vitamin D as our target.) Most men and women require 6000 units per day to achieve this level. There is substantial individual variation, however, with an occasional person needing much more, a rare person requiring as little as 1000 units.


"I bought some vitamin D on sale. They were white tablets."
Time and again, patients in my office who initially have had successful vitamin D replacement, despite being reminded that only oil-based forms should be taken, switch to tablets. While they initially showed a 25-hydroxy vitamin D blood level, for instance, of 67 ng/ml on 8000 units per day with an oil-based capsule, they switch to a tablet form and the next blood level is 25 ng/ml. In other words, tablets are very poorly or erratically absorbed.

I have had people use tablets successfully, however, by taking their vitamin D tablets with a teaspoon of oil, e.g., olive oil. Oil is necessary for full absorption.


"I'm going to Florida. I'll stop my vitamin D because I'm going to lay in the sun."
Wrong. 90% of adults over 40 years old have lost the majority of their ability to activate vitamin D in the skin. A typical response might be an increase in blood level from 25 to 35 ng/ml--a 10 ng increase with a dark brown tan.

There is an occasional person who, with sun exposure, increases blood levels substantially. This can occur in both fair-skinned and dark-skinned people, though I've never seen it happen in an African-American person. The occasional person who maintains the ability to convert vitamin D with sun exposure, or young people, should seasonally adjust their vitamin D dose, e.g., 6000 units winter, 3000 units summer, or some other regimen that maintains desirable blood levels. You can see that monitoring blood levels (we check levels every 6 months for the first 2 years) is crucial: You cannot know what your vitamin D needs are unless you assess 25-hydroxy vitamin D levels.


"I drink plenty of milk. I don't think I need to take vitamin D."
Oh, boy. This is so wrong on so many levels.

First of all, no adult should be drinking plenty of cow's milk. (A discussion for another day.) Second of all, cow's milk averages 70 units of vitamin D, often the D2 form (ergocalciferol), per 8 oz. Even if the FDA-mandated 100 units per day were present, an average adult dose of 6000 units would require 60 glasses of milk per day. Can you say "diarrhea"?

Likewise, other food sources of vitamin D, such as fish (300-400 units per serving) and egg yolks (20 units per yolk), are inadequate. This makes sense: Humans are not meant to obtain vitamin D from food, but from sun exposure over a large body surface area. And this is a phenomenon that is meant to occur only in the youthful, ensuring that nature takes its course and us older folks get old and make way for the young (i.e., unless we intervene by taking vitamin D supplements).


"My doctor said that my vitamin D blood level was fine. It was 32 ng/ml."

Let's face it: By necessity, your overworked primary care physician, who manages gout, hip arthritis, migraine headaches, stomach aches, prostate enlargement, H1N1, depression, etc., is an amateur at nearly everything, expert in nothing. Nobody can do it all and get it right. Likewise vitamin D. The uncertain primary care physician will simply follow the dictates of the laboratory form that specifies "30-100 ng/ml" as the "normal" or "reference range." Unfortunately, the laboratory often quotes population distributions of a lab measure, not an ideal or desirable level.

To illustrate the folly of population distributions of a measure, imagine you and I want to know what women weigh. We go to a local mall and weigh several thousand women. We tally up the results and find that women weigh 172 lbs +/- 25 lbs (the mean +/- 2 standard deviations). (That's true, by the way.) Is that desirable? Of course it isn't. Population average or population distribution does not necessarily mean ideal or desirable.


"My husband's doctor said he should take 4000 units per day. So I just take the same dose."
That would be fine if all adults required the same dose. However, individual needs can vary enormously. A dose that is grossly insufficient for one person may be excessive for another. Once again, vitamin D dose needs can be individualized by assessing 25-hydroxy vitamin levels in the blood.


"I don't need to take vitamin D. I already take fish oil."
I suspect this mistaken belief occurs either because people confuse fish oil with cod liver oil, which does contain some vitamin D. (Cod liver oil is not the best source of vitamin D, mostly because of the vitamin A content; also a discussion for another time), or because they've heard that eating fish provides vitamin D. However, fish oil capsules do not contain vitamin D unless it is added, in which case it should be prominently and explicitly stated on the label.


"I don't have to take vitamin D. It's summer."

For most people I know, if it's a bright, sunny July day, where are they likely to be? In an office, store, or home--NOT lying in the sun with a large body surface area exposed. Also, most people expose no more than 5-10% of surface area in public. I doubt you cut the grass in a bathing suit. Because of modern indoor lifestyles and fashion, the majority of adults need vitamin D supplementation year-round.


I advise everyone that gelcap vitamin D is preferable. Some, though not all, liquid drop forms have also worked. Take a dose that yields desirable blood levels. And blood levels of 25-hydroxy vitamin D are ideally checked every 6 months: in summer and in winter to provide feedback on how much sun activation of D you obtain.

If your doctor is unwilling or unable to perform vitamin D testing, fingerstick vitamin D test kits can be obtained from Track Your Plaque.

Jimmy Moore's thyroid adventure

My friend, Jimmy Moore of Living La Vida Low Carb, describes his thyroid experience here.

As Jimmy points out, he was looking for a way to jump-start a 50-lb weight loss. In my experience, low thyroid hormone levels ("hypothyroidism") are an exceptionally common cause for weight gain. Correcting even marginal hypothyroidism can facilitate weight loss, often resulting in 10 or more pounds of weight loss within the first month.

Unfortunately, Jimmy's thyroid hormone panel proved normal: TSH 1.3, thyroid hormones free T3 and free T4 in the mid- to upper-half of the reference range.

I say "unfortunately" because it is really an easy, inexpensive, and benign solution for losing weight. (I don't, of course, wish that Jimmy or anyone else develops a thyroid condition. But it really can provide gratifying weight loss results when thyroid function is low.) Jimmy might consider taking his oral temperature first thing in the morning as another means of assessing the adequacy of thyroid function.

Perhaps you will be luckier than Jimmy and have thyroid dysfunction that can be corrected and jump-start your weight loss program. Fingerstick thyroid test kits like the one Jimmy used are available here from Track Your Plaque.

What's that in your mouth?




Fat = triglycerides

In other words, eat fat, whether it's saturated, hydrogenated, polyunsaturated, or monounsaturated, and blood levels of triglycerides will go up over the next 6 hours. This remains true if there are carbohydrates in the meal, or if there are NO carbohydrates in the meal. It also remains true if you chronically consume fats.

While fats are the primary determinant of postprandial (after-eating) triglycerides, carbohydrates are the primary determinant of fasting triglycerides.

So, if your triglycerides are high on a fasting cholesterol (lipid) panel, it's most likely because you overconsume carbohydrates.

De Novo Lipo-what?

Humans have limited capacity to store carbohydrates. Beyond the glucose and glycogen in our blood and tissues, we have relatively little carbohydrate to draw from in time of energy need. That's why long-distance runners and triathletes have to carry sugar sources to keep blood sugar from plummeting.

Fat, of course, is different. We have virtually unlimited capacity to store energy as fat.

Because we have limited carbohydrate storage capacity, what can the body do with the excessive quantities of carbohydrates that Americans ingest? What becomes of a bagel for breakfast, wheat crackers for snacks, a whole wheat sandwich for lunch, pretzels, and whole wheat pasta that many people eat every day, not to mention the chips, soft drinks, and juices?

Excess carbohydrates are diverted to an interesting metabolic pathway called de novo lipogenesis (DNL). This refers to the liver's ability to make triglycerides from excessive carbohydrates in the diet. Triglycerides are packaged for release into the blood as VLDL. VLDL, in turn, interacts with other lipoproteins, creating small LDL particles, reduced HDL and smaller, less protective HDL. High VLDL will be measured on a standard cholesterol panel as higher triglycerides.

A University of California (Berkeley, San Francisco) group has done much of the work describing DNL.

A diet weighed towards carbohydrates, especially if 50% or greater calories are carbohydrate, is sufficient to provoke plenty of DNL, even in slender people. DNL is a big part of the reason why low-fat (and, thereby, high-carbohydrate) diets result in higher triglycerides. DNL really gets turned on many-fold if the carbohydrates are "simple," rather than "complex."

Overweight people, however, can demonstrate five-fold greater DNL even with lesser quantities of carbohydrate intake (e.g., 40% fat, 46% carbohydrate, 14% protein):





From Schwarz et al 2003. Mean (± SEM) fractional de novo lipogenesis in lean normoinsulinemic (NI), obese NI, and obese hyperinsulinemic (HI) subjects after 5 d of consuming a high-fat, low-carbohydrate diet and in different lean NI and obese HI subjects after 5 d of consuming a low-fat, high-carbohydrate diet. Values with different superscript letters are significantly different.


Excessive carbohydrates, a la standard low-fat diets, are good for nobody. The concept of de novo lipogenesis fills in a theoretical hole that now explains why people who eat carbohydrates have higher triglycerides, VLDL, and, eventually, insulin resistance and diabetes.

Gretchen's postprandial diet experiment II

I previously posted Gretchen's postprandial diet experiment, in which she consumed a low-fat diet for a day, followed by a low-carbohydrate diet for a day. Grethen monitored blood glucose and triglycerides with fingerstick checks. (Blood glucose can be checked on any widely available glucose monitor; triglycerides can be monitored with the Cardiochek device.)

Let's now discuss what happened.

On the low-carb, high-fat day, there was an initial surge in triglycerides to 250 mg/dl late morning, followed by a secondary peak several hours following dinner. Because fat is mostly triglycerides, Gretchen's high-fat (sausage, bacon, butter, whole-fat yogurt) breakfast provided a large quantity of triglycerides that needed to be absorbed. This generally occurs over approximately 6 hours, varying depending on body weight, how accustomed you are to fat, activity level during the day, the kind of fat in the meal. The high content of saturated fat in Gretchen's high-fat breakfast likely caused the somewhat slower drop in triglycerides over approximately 7 1/2 hours.

As Gretchen herself had noted, triglycerides the following day were lower, a typical low-carb response. Blood sugar throughout showed only minor variation, with only small postprandial increases.

Thus, Gretchen experienced what we'd expect with a low-carb, high-fat diet: an initial high surge in triglycerides, followed by a decline in fasting levels, while blood sugar shows a normal contour.







Now, the more confusing low-fat experience:



Blood glucose makes a striking peak at 200 mg/dl after the low-fat breakfast of pasta and rice, in contrast to the low-carb breakfast. Triglycerides behaved very differently from the low-carb experiment: While there was no initial postprandial surge, there was a late surge developing 6-24 hours later. The late surge continued into the next day, with fasting levels the following morning (210 mg/dl) exceeding the starting triglyceride level (60 mg/dl).

The one potentially confusing aspect of all this is Gretchen's late rise in triglycerides on the low-fat diet. This phenomenon is due to something called de novo lipogenesis, or the liver's conversion of carbohydrates to triglycerides that occurs when an excessive carbohydrate load comes through diet. Because the human body cannot store anything beyond a minor quantity of carbohydrates (as glucose and glycogen), carbohydrates are converted to fats.

Another factor causing the late triglyceride increase is insulin resistance, given the high blood sugar response. When insulin resistance is present, the activity of the enzyme, lipoprotein lipase, is reduced. Less lipoprotein lipase activity allows slower VLDL degradation, allowing VLDL (and thereby triglycerides contained in VLDL) to "stack up" in the blood. Thus, the higher triglycerides late after eating and into the next morning.

One issue to be aware of: Acute responses can differ from chronic responses. In other words, had Gretchen had the luxury (and time and money) to conduct the experiment over, say, 4 weeks, rather than a single day, there would be somewhat different responses. The best data on this come from Dr. Jeff Volek of the University of Connecticut, in which 4 weeks of low-carbohydrate eating modify fasting and postprandial responses over time.

Several conclusions can be made from Gretchen's experience:

1) Low-carb, high-fat acutely generates extravagant postprandial triglyceride responses.
2) Low-fat causes a late triglyceride surge and higher fasting triglycerides.
3) Low-fat leads to high blood sugars and, by implication, diabetes.


Both the low-carb and the low-fat responses are undesirable, both leading to increased risk for heart disease. Which is worse? I believe that low-fat is more destructive, since it leads over time to both high triglycerides and diabetes, while low-carb/high-fat only leads to postprandial triglyceride surges, at least acutely.

How to best balance the responses to reduce risk for heart disease? That's a discussion for future.


Again, my thanks to Gretchen and the substantial amount of effort that went into generating these numbers. More of Gretchens' own writing can be found on her blogs:

A wheat-free 2010

A Heart Scan Blog reader sent this fascinating description of his wheat-free adventure.

Whenever I discuss this notion of going wheat-free and the incredible health effects that develop, I invariably receive comments or emails saying something like "I eat wheat and feel fine. That can't be true." The problem is that not everybody needs to go wheat-free. 20-30% of people can include wheat in their diet and suffer little more than weight gain, some not at all.

But stories like Michael's (below) are commonplace in my experience. I've had many patients who, at first, refused to believe that wheat exposure might be the underlying cause for health struggles. But they finally give it a try and find that rashes, arthritis, acid reflux, irritable bowel symptoms, mood swings, anger, etc. are miraculously improved or gone.

Anyway, hear what Michael has to tell us:


Dr. Davis,

I want to thank you. I was browsing the web a while back and happened to stumble upon your blog post about wheat belly. The first thing that caught my attention was that I thought you had somehow gotten a photograph of me. The young man you posted an image of looked exactly like me. So I read what you had to say. After reading, I thought "Four weeks isn’t so bad. I think I can handle this."

It has now been nine weeks and all I can say is that I am completely amazed. Let me say first that twice in the past twenty years I have been tested for allergies. The first time I was tested I showed a slight reaction to Timothy Grass, but not enough to cause me any problems. The second testing I did not show a reaction to anything. So, I have always assumed that my chronic sinus problem were due to sensitivities to environmental pollutions. Now I am not so sure. I would like to list for you everything that has happened to me since I eliminated wheat from my diet.

1. I have lost a total of 12 pounds in the last 9 weeks.
2. I have lost 1 ¼ inches of belly fat
3. I have lost a tremendous amount of fat from my neck.
4. My entire life I have had problems with oily hair. I could wash my hair and three hours later I looked as if I hadn’t washed in a week. Now my hair stays clean and soft for two to three days without shampoo.
5. My hair was always flat and stringy. Now it has lots of body.
6. I used to have thick layers of dry skin on my scalp. It would come loose in chunks as large as a fingernail. That dry scalp is gone.
7. I used to have dry flaky skin that seemed to secrete oil. That no longer happens. My skin is now soft and smooth.
8. I have lived with bad acne for at least 35 years. Now it is hard to find a pimple on my body.
9. I have always had to fight dehydration. That is no longer a problem.
10. I used to drink two large cups of coffee every morning just to be able to function. I now have enough energy that I have eliminated caffeine from my diet.
11. I sleep more soundly than ever before and my dreams are clear and vivid.
12. My thought processes are more active and clear than they have ever been.
13. My chronic sinus issue is now a thing of the past.
14. I used to have problems with getting the “shakes” if I had gone more than a couple of hours without eating. It was as if I was suffering from low blood sugar. I would even be afraid that I would pass out. Now all I feel is hunger. I can go all day without eating and never feel in danger of losing consciousness.


Today is Thursday. This past Monday my wife and I were eating out and I ordered a burger without a bun. What I didn’t realize was that the burger would arrive covered in onion rings. I knocked the mountain of onion rings onto the plate but there were still a couple that were embedded in the cheese. I decided, what the hell, a couple of onion rings shouldn’t make that much of a difference. I will not make that mistake again anytime soon. Within 30 minutes I felt like there was a steel spike going through my left eye socket. I don’t remember ever being in that much pain. My sinuses were exploding. This morning, as I write this, I still feel the vestiges of that pain. Just enough that I know it is there. But after two and a half days, I am at least able to function again.

I owe you a debt of gratitude. You may have just saved my life. In the very least you have given me the means to improve my life in ways that I never thought possible.

Thank you so much,
Michael B.



Now, if wheat exposure can do that in Michael, what damage can it do in other people?

Personally, I previously experienced many of the same symptoms that Michael suffered, all gone with wheat elimination.

My advice: If you have any inkling that you might have a wheat sensitivity, make a New Year's resolution to stay wheat-free for 4 weeks and see whether you can feel any difference. Not everybody will, but many will be telling us about the dramatic health turnarounds they experienced.

Lipoprotein lipase and you

Lipoprotein lipase can make the difference between having heart disease and not having it. Having sky-high triglycerides or normal triglycerides. It can mean dinner hanging around for over 12 hours in the bloodstream, rather than the usual 4-6 hours.

If you take niacin, you must exercise

We use a lot of niacin in the Track Your Plaque program.

Niacin:

--Increases HDL and shifts HDL towards the large, protective fraction

--Reduces small LDL--In fact, niacin is the best treatment we have to reduce small LDL after wheat elimination and carbohydrate reduction.

--Reduces fasting and postprandial (after-eating) triglycerides

--Reduces heart attack risk by 20-28%--even as a sole agent.


But . . . niacin also triggers higher blood sugar because it partially blocks the effects of insulin (insulin "resistance").

While the net effect of niacin remains positive, the provocation of insulin resistance is not such a good thing. Can it be minimized or eliminated?

Yes, through exercise. Here's one interesting observation in obese (BMI 34.0), sedentary men given placebo, exercise, niacin (1500 mg Niaspan, once per day), or niacin + exercise:





From Plaisance et al 2008.

Blood was drawn following a high-fat meal challenge. (Yes, a high-fat challenge, not a carbohydrate challenge. In this study, there were only 17 grams carbohydrates in the test meal, but 100 grams fat. More on this in future.) Exercise consisted of walking for 50 minutes at a moderate pace one hour prior to the meal challenge.

You can see from the graph that exercise partially corrected the increased insulin level provoked by niacin.

Judging from this and other studies, exercise can help minimize the insulin-blocking effects of niacin. It doesn't take much, just moderate exercise for at least 30 minutes.

Adequate sleep can also help, since sleep deprivation is a potent trigger for insulin resistance, only worsened in the presence of niacin. Vitamin D supplementation to achieve desirable blood levels (which I define as 60-70 ng/ml) is also an effective means to minimize this effect.
