Lessons from the 20-year statin experience

Readers of the Heart Scan Blog know that, while I recognize that statins are useful in a small segment of the population with genetically-determined disorders, they are wildly overused, misused, and abused. In my view, the majority of people taking statins have no business doing so and could, in fact, obtain superior results by following some of the strategies advocated in these pages.

Nonetheless, the 30-year long statin experience has taught us some important lessons. Statin drugs have enjoyed more "research" than any other class of drugs ever conceived. They have received more media attention and embraced by more physicians than any other class of drugs. Combine these social phenomena and I believe that several lessons can be learned:

Small LDL particles and increased HbA1c--An evil duo

Small LDL particles are triggered by consumption of carbohydrates. Eat more "healthy whole grains," for instance, and small LDL particles skyrocket.

Increased hemoglobin A1c, HbA1c, a reflection of the last 60-90 days' blood sugars, is likewise a reflection of carbohydrate consumption. The greater the carbohydrate consumption and/or carbohydrate intolerance, the greater the HbA1c. Most regard a HbA1c of 6.5% or greater diabetes; values of 5.7-6.4% pre-diabetes. However, note that any value of 5.0% or more signifies that the process of glycation is occurring at a faster than normal rate. Recall that endogenous glycation, i.e., glucose modification of proteins, ensues whenever blood sugars increase over the normal range of 90 mg/dl (equivalent to HbA1c of 4.7-5.0%). Glycation is the fundamental process that leads to cataracts, arthritis, and atherosclerosis.

Put the two together--increased quantity of small LDL particles along with HbA1c of 5.0% or higher--and you have a powerful formula for heart disease and coronary plaque growth. This is because small LDL particles are not just smaller; they also have a unique conformation that exposes a (lysine residue-bearing) portion of the apoprotein B molecule contained within that makes small LDL particles uniquely glycation-prone. Compared to large LDL particles, small LDL particles are 8-fold more prone to glycation.

So glycated small LDL particles are present when HbA1c is increased above 5.0%. Small, glycated LDL particles are poorly recognized by the liver receptor that ordinarily picks up and disposes LDL particles, unlike large LDL particles, meaning small LDL particles "live" much longer in the bloodstream, providing more opportunityt to do its evil handiwork. Curiously, small LDL particles are avidly taken up by inflammatory white blood cells that can live in the walls of arteries, where they are oxidized--"glycoxidized"--and add to coronary atherosclerotic plaque.

The key is therefore to tackle both small LDL particles and HbA1c.

Unforgiving small LDL particles

Small LDL particles are triggered by carbohydrates in the diet: Eat carbohydrates, small LDL particles go up. Cut carbohydrates, small LDL particles go down.

A typical scenario would be someone starts with, say, 2000 nmol/L small LDL (by NMR) because they've been drinking the national Kool Aid of eating more "healthy whole grains" and consuming somewhere around 200 grams carbohydrates per day, including the destructive amylopectin A of wheat. This person slashes wheat followed by limiting other carbohydrates and takes in, say, 40-50 grams per day. Small LDL: 200 nmol/L.

In other words, reducing carbohydrate exposure slashes the expression of small LDL particles, since carbohydrate deprivation disables the liver process of de novo lipogenesis that forms triglycerides. Abnormal or exaggerated postprandial (after-eating) lipoproteins that are packed with triglycerides are also reduced. Because triglycerides provide the first lipoprotein "domino" that cascades into the formation of small LDL particles, carbohydrate reduction results in marked reduction in small LDL particle formation.

So let's say you are doing great and you've slashed carbohydrates. Small LDL particles are now down to zero--no small LDL whatsoever. What LDL particles you have are the more benign large variety, say, 1200 nmol/L (LDL particle number), all large, none small. You are due for some more blood work on Thursday. On Tuesday, however, you have four crackers because, what the heck, you've been doing great, you've lost 43 pounds, and have been enjoying dramatic correction of your lipoprotein abnormalities.

Your next lipoprotein panel: LDL particle number 1800 nmol/L, small LDL 700 nmo/L--substantially worse, with a major uptick in small LDL.

That's how sensitive small LDL particles can be to carbohydrate intake. And the small LDL particles can last for up to several days, since small LDL particles are not just smaller in size, they also differ in conformation, making them unrecognizable by the normal liver receptor. The small LDL particles triggered by the 4 crackers therefore linger, outlasting the normal-conformation large LDL particles that are readily cleared by the liver.

This phenomenon is responsible for great confusion when following lipoprotein panels, since a 98% perfect diet can yield dismaying results just from a minor indulgence. But, buried in this simple observation is the notion that small LDL particles are also extremely unforgiving, being triggered by the smallest carbohydrate indulgence, lasting longer and wreaking their atherosclerotic plaque havoc.

I eliminated wheat . . . and I didn't lose weight!

Elimination of wheat is a wonderfully effective way to lose weight. Because saying goodbye to wheat means removing the gliadin protein of wheat, the protein degraded to brain-active exorphins that stimulate appetite, calorie consumption is reduced, on average, 400 calories per day. It also means eliminating this source of high blood sugar and high blood insulin and the 90-minutes cycles of highs and lows that cause a cyclic need to eat more at the inevitable low. It means that the high blood sugar and insulin phenomena that trigger accumulation of visceral fat are now turned off. It may possibly also mean that wheat lectins no longer block the leptin receptor, undoing leptin resistance and allowing weight loss to proceed. And weight loss usually results effortlessly and rapidly.

But not always. Why? Why are there people who, even after eliminating this appetite-stimulating, insulin-triggering, leptin-blocking food, still cannot lose weight? Or stall after an initial few pounds?

There are a list of reasons, but here are the biggies:

1) Too many carbohydrates--What if I eliminate wheat but replace those calories with gluten-free breads, muffins, and cookies? Then I've switched one glucose-insulin triggering food for another. This is among the reasons I condemn gluten-free foods made with rice starch, cornstarch, tapioca starch, and potato starch. Or perhaps there's too many potatoes, rices, and oats in your diet. While not as harmful as wheat, they still provoke phenomena that cause weight loss to stall. So cutting carbohydrates may become necessary, e.g., no more than 12-14 grams per meal.

2) Fructose--Fructose has become ubiquitous and has even assumed some healthy-appearing forms. "Organic agave nectar" is, by far, the worst, followed by maple syrup, honey, high-fructose corn syrup, sucrose,and fruit--yes, in that order. They are all sources of fructose that causes insulin resistance, visceral fat accumulation or persistency, prolongation of clearing postprandial (after-meal) lipoproteins that antagonize insulin, and glycation. Lose the fructose sources--as much of it as possible. (Fruit should be eaten in very small portions.) Watch for stealth sources like low-fat salad dressings--you shouldn't be limiting your fat anyway!

3) Thyroid dysfunction--A real biggie. Number one cause to consider for thyroid dysfunction: iodine deficiency. Yes, it's coming back in all its glory, just like the early 20th century before iodized salt made it to market shelves. Now, people are cutting back on iodized salt. Guess what's coming back? Iodine deficiency and even goiters. Yes, goiters, the disfiguring growths on the neck that you thought you'd only see in National Geographic pictures of malnourished native Africans. Number two: Exposure to factors that block the thyroid. This may include wheat, but certainly includes perchlorate residues (synthetic fertilizer residues) on produce, pesticides, herbicides, polyfluorooctanoic acid residues from non-stick cookware, polybrominated diphenyl ethers (flame retardants), and on and on. If you are iodine-deficient, it can even include goitrogenic iodine-blocking foods like broccoli, cauliflower, and soy. Thyroid status therefore needs to be assessed.

4) Cortisol--Not so much excess cortisol as disruptions of circadian rhythm. Cortisol should surge in the morning, part of the process to arouse you from sleep, then decline to lower levels in the evening to allow normal recuperative sleep. But this natural circadian cycling is lost in many people represented, for instance, as a flip-flopping of the pattern with low levels in the morning (with morning fatigue) and high levels at bedtime (with insomnia), which can result in stalled weight loss or weight gain. Cortisol status therefore needs to be assessed, best accomplished with salivary cortisol assessment.

5) Leptin resistance--People who are overweight develop an inappropriate resistance to the hormone, leptin, which can present difficulty in losing weight. This can be a substantial issue and is not always easy to overcome. It might mean assessing leptin levels or it might mean taking some steps to overcome leptin resistance.

Okay, that's a lot. Next: More on how to know when thyroid dysfunction is to blame.

Do the math: 41.7 pounds per year

Consumers of wheat take in, on average, 400 calories more per day. Conversely, people who eliminate wheat consume, on average, 400 calories less per day.

400 calories per day multiplied by 365 days per day equals 146,000 additional calories over the course of one year. 146,000 calories over a year equals 41.7 pounds gained per year. Over a decade, that's 417 pounds. Of course, few people actually gain this much weight over 10 years.

But this is the battle most people who follow conventional advice to "cut your fat and eat more healthy whole grains" are fighting, the constant struggle to subdue the appetite-increasing effects of the gliadin protein of wheat, pushing your appetite buttons to consume more . . . and more, and more, fighting to minimize the impact.

So, if you eat "healthy whole grains" and gain "only" 10 pounds this year, that's an incredible success, since it means that you have avoided gaining the additional 31.7 pounds that could have accumulated. It might mean having to skip meals despite your cravings, or exercising longer and harder, or sticking your finger down your throat.

400 additional calories per day times 365 days per year times 300,000,000 people in the U.S. alone . . . that's a lot of dough. Is this entire scenario an accident?

Or, of course, you could avoid the entire situation and kiss wheat goodbye . . . and lose 20, 30, or 130 pounds this year.

We got the drug industry we deserve

A biting commentary on just who is writing treatment guidelines for diabetes and cardiovascular disease was published in the British Medical Journal, summarized in theHeart.org's HeartWire here.

"About half the experts serving on the committees that wrote national clinical guidelines for diabetes and hyperlipidemia over the past decade had potential financial conflicts of interest (COI), and about 4% had conflicts that were not disclosed.

"Five of the guidelines did not include a declaration of the panel members' conflicts of interest, but 138 of the 288 panel members (48%) reported conflicts of interest at the time of the publication of the guideline. Eight reported more than one conflict. Of those who declared conflicts, 93% reported receiving honoraria, speaker's fees, and/or other kinds of payments or stock ownership from drug manufacturers with an interest in diabetes or hyperlipidemia, and 7% reported receiving only research funding. Six panelists who declared conflicts were chairs of their committee.

"Of the 73 panelists who had a chance to declare a conflict of interest but declared none, eight had undeclared COI that the researchers identified by searching other sources. Among the 77 panel members who did not have an opportunity to publicly declare COI in the guidelines documents, four were found to have COI.
"

The closing quote by Dr. Edwin Gale of the UK is priceless:
"Legislation will not change the situation, for the smart money is always one step ahead. What is needed is a change of culture in which serving two masters becomes as socially unacceptable as smoking a cigarette. Until then, the drug industry will continue to model its behavior on that of its consumers, and we will continue to get the drug industry we deserve."

It's like having Kellogg's tell us what to each for breakfast, or Toyota telling us what car to drive. The sway of the drug industry is huge. Even to this day, I observe colleagues kowtow to the sexy sales rep hawking her wares. But that's the least of it. Far worse, even the "experts" who we had trusted to have objectively reviewed the evidence to help the practitioner on Main Street appears to be little more than a hired lackey for Big Pharma, hoping for that extra few hundred thousand dollars.

Wheat "debate" on CBC

"Many Canadians plan warm buns, stuffing and pie for their Thanksgiving meals tonight. But I'll speak with a cardiologist who thinks we have no reason to be thankful for any food that contains wheat. William Davis says our daily bread is making us fat and sick."

That's the introduction to my recent interview and debate on CBC, the Canadian public radio system, aired on the Canadian Thanksgiving. Arguing the other side was Dr. Susan Whiting, an academic nutritionist. (I use the word "arguing" loosely, since she hardly argued the issues, certainly hadn't read the book, but was content to echo the conventional line that whole grains are healthy and cutting out a food group is unhealthy.)

I do have to give credit to the Canadian media, including the CBC, who have been hosting some rough-and-tumble discussions about the entire wheat question despite Canada being a world exporter of wheat. I recently participated in another debate with a PhD nutrition expert from Montreal who, in response to my assertion that the genetically-altered high-yield, semi-dwarf strains have changed the basic composition of wheat, argued that the creation of the 2-foot tall semi-dwarf strain was a convenience created so that farmers could see above their fields--no kidding. I stifled my laugh. (The semi-dwarf variants were actually created to compensate for the heavy seed head that develops with vigorous nitrate fertilization that buckles 4 1/2-foot tall wheat stalk, making harvesting and threshing impossible, a process farmers call "lodging." The 2-foot tall semi-dwarf thick, stocky stalk is strong enough to resist lodging.)

In short, debating the nutrition "experts" on this question has been tantamount to arguing with a school age child on the finer points of quantum physics. There has not yet been any real objection raised on the basic arguments against modern genetically-altered wheat. Modern semi-dwarf wheat is, and remains, an incredibly bad creation of the genetics laboratories of the 1970s. It has no business on the shelves of your grocery store nor on the cupboards in your home.

Carrot Cake

This is among my favorite recipes from the Wheat Belly book. I reproduce it here for those of you who read the Kindle or audio version and therefore didn't get the recipes.

I made this most recently this past weekend. It was gone very quickly, as even the 13-year old gobbled it up.

(I reduced the sour cream in this version from 8 to 6 oz to reduce cooking time. Also, note that anyone trying to avoid dairy can substitute more coconut milk, i.e., the thicker variety, in equivalent quantities.)

Why wheat makes you fat

How is it that a blueberry muffin or onion bagel can trigger weight gain? Why do people who exercise, soccer Moms, and other everyday people who cut their fat and eat more "healthy whole grains" get fatter and fatter? And why weight gain specifically in the abdomen, the deep visceral fat that I call a "wheat belly"?

There are several fairly straightforward ways that wheat in all its varied forms--whole wheat bread, white bread, multigrain bread, sprouted bread, sourdough bread, pasta, noodles, bagels, ciabatta, pizza, etc. etc.--lead to substantial weight gain:

High glucose and high insulin--This effect is not unique to wheat, but shared with other high-glycemic index foods (yes: whole wheat has a very high-glycemic index) like cornstarch and rice starch (yes, the stuff used to make gluten-free foods). The high-glycemic index means high blood glucose triggers high blood insulin. This occurs in 90- to 120-minute cycles. The high insulin that inevitably accompanies high blood sugar, over time and occurring repeatedly, induces insulin resistance in the tissues of the body. Insulin resistance causes fat accumulation, specifically in abdominal visceral fat, as well as diabetes and pre-diabetes. The more visceral fat you accumulate, the worse insulin resistance becomes; thus the vicious cycle ensues.

Cycles of satiety and hunger--The 90- to 120-minute glucose/insulin cycle is concluded with a precipitous drop in blood sugar. This is the foggy, irritable, hungry hypoglycemia that occurs 2 hours after your breakfast cereal or English muffin. The hypoglyemia is remedied with another dose of carbohydrate, starting the cycle over again . . . and again, and again, and again.

Gliadin proteins--The gliadin proteins unique to wheat, now increased in quantity and altered in amino acid structure from their non-genetically-altered predecessors, act as appetite stimulants. This is because gliadins are degraded to exorphins, morphine-like polypeptides that enter the brain. Exorphins can be blocked by opiate-blocking drugs like naltrexone. A drug company has filed an application with the FDA for a weight loss indication for naltrexone based on their clinical studies demonstrating 22 pounds weight loss after 6 months treatment. Overweight people given an opiate blocker reduce calorie intake 400 calories per day. But why? There's only one food that yields substantial quantities of opiate-like compounds in the bloodstream and brain: wheat gliadin.

Leptin resistance--Though the data are preliminary, the lectin in wheat, wheat germ agglutinin, has the potential to block the leptin receptor. Leptin resistance is increasingly looking like a fundamental reason why people struggle to lose weight. This might explain why eliminating, say, 500 calories of wheat consumption per day yields 3500 calories of weight loss.

And, as in many things wheat, the whole is greater than the sum of the parts. Despite all we know about this re-engineered thing called wheat, eliminating it yields health benefits, including weight loss, that seem to be larger than what you'd predict with knowledge of all its nasty little individual pieces.

Just who is "Real Facts 2000"?

This is an example of what seems to be developing over at Amazon.com, posted as a "book review":

The author has no credentials, no credibility, just a small cult of terribly misinformed followers. Don't be fooled by the high volume screech against wheat and grains. Allegations of "secret ingredients in wheat" to make you eat more, or comparisons to cigerettes. Seriously?! For over 8000 years wheat has sustained and grown human kind, oh and it tastes good when mixed with a little water and yeast. Every nutritionist and serious medical professional will tell you that bread is the most economical and safe source of essential nutrients. In fact, bread is handed out in natural disasters because it sustains life without food safety issues or requiring refrigeration. And now, suddenly it will kill you. Comical! This book is such a bone headed, misinformed way to just scare people into not eating.

As for secret ingredients, humm, apparently the author is ignorant of the food laws that regulate everything that goes into food and on food labels. Unlike some enforcement agencies, the FDA has some serious teeth behind its enforcement. As for frankenwheat, again seriously?! Wheat, due to its ubiquitous presence in the world is treated as sacrosant from any GMO research or development.

If you need real, science based information on healthy eating, check out [...] and leave this book and its cult in the compound.


If you recognize the wording and tone, you will readily recognize the footprints of the Wheat Lobby here. "Terribly misinformed followers"? . . . Hmmm. "Food laws"? I didn't realize that eating more "healthy whole grains" was a . . . law?

Make no mistake: There are people and organizations who have a heavy stake in your continued consumption of the equivalent of 300 loaves of bread per year. There are people and organizations (read: pharmaceutical industry) who have a big stake on the "payoff" of your continued consumption of "healthy whole grains."

This is not a book review; this is part of a concerted, organized campaign to discredit a message that needs to be heard.

Anybody from the media listening?

A new Track Your Plaque record: 63% reduction

Stress can booby-trap the best efforts at reducing your CT heart scan score.

But Amy, our newest Track Your Plaque record holder, defied the effects of an overwhelmingly life stress to drop her heart scan score from 117 to 43--an amazing 63% reduction.

Amy beat our previous record holder, Neal, who achieved a 51% reduction. Though Neal had dropped his score from 339 to 161, a drop of 178 and more than Amy's 74 point drop, on a percentage basis Amy holds the record.

I'm also especially gratified that a woman now holds our record. I'm uncertain why, but the ladies have been shy and the men remain the dominant and vocal participants in our program. Speak up, ladies!

Amy's complete story can be found in our latest Track Your Plaque Newsletter to be released later this week, as well as an upcoming feature on the www.cureality.com website. (We've got to toot our horn about successes like this!)

The Ornish diet made me fat

I got that kind of question today that tempts me to roll my eyes and say, "Not again!"

"If I want to reverse my heart scan score, should I do the Ornish diet?" You know, the one by Dr. Dean Ornish: Dr. Dean Ornish's Program for Reversal of Heart Disease.

I personally followed the Ornish program way back in the early 1990s. I reduced fat intake of all sorts to <10% of calories; eliminated all fish and meats, vegetable oils, and nuts; ate vegetables and fruits; and upped my reliance on whole grains. I used many of his recipes. I exercised by running 5 miles per day. (Far more than I do now!) I avoided sweets like candies and fruit juices.

What happened?

I gained 31 lbs, going from 155 to 186 lbs (I'm 5 ft 8 inches tall), my abdomen developed that loose, fleshy look, hanging over my beltline. My HDL plummeted to 28 mg/dl, triglycerides skyrocketed to 336 mg/dl, and I developed a severe small LDL pattern. I experienced a mental fogginess every afternoon. I felt tired and crabby much of the time. I sometimes struggled to suppress an irrational anger and frustration over the silliest things. I required huge amounts of coffee just to function day to day.

Hundreds of my patients suffered similar phenomena.

Few of us wear bell-bottomed jeans, tie-dyed t-shirts, or say "groovy". Rowan and Martin's Laugh-in is an "oldie", it's no longer cool to hold your index and middle fingers up in the "V" sign of peace. Even Ladybird Johnson has passed.

So should go the misadventures of the ultra low-fat diet, as articulated by Dr. Ornish. His day came and went. We learned from our mistakes. Now let's do something better.

Keep your eyes open for the New Track Your Plaque Diet.

Do lower heart scan scores grow faster?

If Mary's heart scan score increases from 2 to 4 in one year, it represents a 100% increase in score.

If Jane's heart scan score increases from 1002 to 1004 over the same period, it represents <1% increase, even though the true growth is the same: 2 points.

This quirk of arithmetic needs to be factored in whenever you and your doctor try to puzzle out the meaning of an increasing CT heart scan score. Lower numbers, particularly those <100, can grow at seemingly much faster rates if viewed by percent per year increase. If no effort is taken to stop the growth in your coronary plaque, then scores of 10, 20, 30, or the like can easily grow 50-100% per year.

In contrast, scores of 1000, 1500, and 2000 tend to grow at "slower" rates of 20% or so per year without corrective efforts, even though the absolute growth may be substantial. (Obviously, this bit of confusion can be best eliminated by reducing your heart scan score, but it doesn't always work out that way.)

If we were all adept at advanced math, we should probably rely on logarithmic measures of plaque increase, rather than percent increase. Or, you can just keep in mind that the rate of plaque growth must always be viewed in the context of the absolute score.

Mr. Salazar: Check your Lp(a)

Marathon star Alberto Salazar was just released from the hospital following a heart attack and a heart catheterization that led to a stent. The MSNBC version of the report can be viewed at http://www.msnbc.msn.com/id/19653682/.

At 48 years old and holder of several American records for marathon times, Salazar's story is eerily reminiscent of Jim Fixx, who died at age 52 after writing a bestselling book, The Complete Book of Running. Thankfully, Salazar's story has a happier ending.

Fixx died at a time when prevention of heart disease was quite primitive. Lipoprotein analysis was not broadly available to the public, CT heart scans had not yet been invented. Even statin drugs were just a gleam in the pharmaceutical industry's eye.

But not so with Salazar. This Cuban-born marathoner experienced his heart attack at at a time when enormously useful steps can be taken to 1) document the extent of disease with a CT heart scan (the presence of a stent just means that one artery can't be "scored"), and 2) identify the causes of his disease.

I suspect that the fact that yet another marathoner in the limelight will once again prompt the (likely non-sensical) conversation about long-distance running and the increased risk of heart disease. Unfortunately, I fear that the real cause will be left unidentfied and untreated: Lipoprotein(a), or Lp(a).

It's almost certain that Fixx had Lp(a), given the fact that his dad had a heart attack at age 35. Running simply postponed the untreated inevitable.

I hope Mr. Salazar is surrounded by doctors who have his true interests in mind (not just procedural excitement) and ask the crucial question: Why?

The answer is almost certain to be Lp(a).

Heart Scan Curiosities #8: Fat heart

Here's a curious incidental finding on a heart scan: an unusual fat accumulation around the heart.



The arrows point to an unusually large accumulation of fat tissue on either side of the heart. This man was mildly but not excessively overweight at 5 ft 10 inches and 201 lbs.

I know of no specific implications of this curiosity. It makes me wonder if he was very obese at one time and has since lost the weight.

Chocolate and blood pressure

A recent very detailed and clean study on the effects of a small serving of dark chocolate on blood pressure was just published in the Journal of the American Medical Association.

I was going to do a little Blogging on this interesting study but I read the Fanatic Cook's wonderfully insightful comments. I'd direct you to her discussion, instead: A small daily dose of dark chocalate lowers blood pressure at http://fanaticcook.blogspot.com/. I couldn't have said it any better.

By the way, the authors of the study had no financial ties to the chocolate or cocoa industry. Refreshing.

Does prevention save money?

Prevention and reversal of heart disease are undoubtedly preferable to the current crash and repair model currently followed by doctors and hospital, the model that has created an enormous medical device industry to support it.

But does it save money? This debate often boils down to a metric of "lives saved per $100,000". Thus, the statin drugs (of course) have been subjected to such analyses and have been shown to be "cost-effective."

But how does a powerful heart disease prevention and reversal program like Track Your Plaque compare to the current crash and repair procedural approach to heart disease? This is a very difficult analysis, one that is subject to enormous variation, depending on the population studied and the prevalence of disease, the local practice habits (e.g., in the northwest Cleveland suburb of Lorain, virtually everybody going to the hospital for any heart problem gets one or several heart catheterizations), and other factors.

There's also the difficulty of what should constitute a prevention program. Is it like that used in the COURAGE Trial of "optimal medical therapy" that included nitroglycerin, aspirin, a beta blocker, and statin drug (which we regard as a laughably silly approach), or one like Track Your Plaque in which we try to correct the causes of heart disease, not just palliate (BandAid) them? Costs vary. The "optimal medical therapy" is very costly due to its reliance on medications to treat symptoms. Our program is somewhat costly because of the reliance on a CT heart scan and lipoprotein analysis (though, in the long perspective, our costs are modest).

We asked this question and came up with a lengthy analysis. Bottom line: Following the Track Your Plaque program saves enormous sums of money. Because of the complexity of the analysis, which is theoretical and not a real-world test, we confined our analysis to men in the 40-59 year old age group. If this group alone were to subscribe to a intensive but rational program of prevention like Track Your Plaque, over $20 billion dollars per year would be saved.

If the analysis were extended to women of all ages and men older than 59, the numbers would balloon to many more tens of billions of dollars. Such a savings wouldn't cure the healthcare system's growing financial crisis, but it sure would be a big help. Sort of like converting to a hydrid car--you don't eliminate the need for gas, but you'll save a lot in fuel costs.

The Track Your Plaque approach makes sense because it is, bar none, the most powerful approach to gaining hold of heart disease risk available. But it also makes sense from a financial standpoint. Now, if we can only convince the hospitals, the $30 million annual salary device manufacturer CEO, and my procedure-crazy colleagues that this way makes more sense.

Watch for our analysis on an upcoming Track Your Plaque Special Report.

Where should fiber come from?

Ray had the usual protuberant belly overhanging his beltline of someone who was over-reliant on processed starches, particularly wheat.

After all, he ran a sandwich bakery. He sheepishly admitted that he ate the products of his own production line every day while at work, even bringing a few sandwiches home.

At 5 ft 10 inches, 201 lbs, he wasn't terribly overweight, but all the excess was in his beltline. He had the lipoproteins to match: HDL 38 mg/dl, triglycerides 180 mg/dl, 83% of all LDL particles were small, excess VLDL and IDL. Blood pressure: 140/88. Blood sugar: 112 mg/dl.

With a CT heart scan score of 698, Ray had some work to do.

Among the strategies we discussed was a need to dramatically reduce, perhaps eliminate, wheat products and other high-glycemic index foods.

"You've got to be kidding me!" Besides the inconsistency with his business, he was puzzled on what foods were edible for his pattern. We discussed how he could easily replace his reliance on wheat and breads with more vegetables, more fruits, more lean proteins, and more healthy oils.

"But I won't get any fiber!" he declared. That was why he tried to choose whole wheat bread for his sandwiches.

This is a common concern when we discuss how grains, particuarly wheat, need to be sharply reduced. In the most recent edition of his Paleo Diet Newsletter, Dr. Loren Cordain has laid out a wonderful graph that beautifully illustrates the issue:




(From The Paleo Diet Newsletter at http://www.thepaleodiet.com/newsletter/back_issues.shtml)


In other words, reducing or eliminating "fiber-rich" grains and replacing their calories dramatically increases fiber content of your diet.

For Ray, whose livelihood depends on promoting and perpetuating the use of wheat breads, it will be tough to keep him on the right track. My prediction: the results he will see will be substantial and it will become difficult to return to eating his own products.

There's no doubt that this concept can be economically disruptive for many people, including Ray. It's a tough situation we've created: a huge industrial complex based on growing grains and wheat, processing it into breakfast cereals, bagels, pretzels, crackers, and sandwiches. But it has also contributed to the epidemic of obesity and the patterns that people like Ray have.

But the startling fact remains: If replaced with vegetables and fruits, reducing grains increases the fiber content of your diet, and not jsut a little bit, but enormously. If green peppers and spinach had brand names like "Fiber One" and "Smart Start" along with flashy boxes, then maybe it would be an easier concept to grasp.

The Detection Gap

You've heard of the Generation Gap, the Income Gap, the Technology Gap, the Gender Gap, and the Achievement Gap.

How about the Detection Gap?

Haven't heard of it? That's the gap between coronary heart disease detected by conventional methods widely practiced in the community and the real prevalence of the disease.

The standard approach to coronary heart disease detection is a relatively simple formula. One of three things are sought:

1) Symptoms of heart disease like chest pain or breathlessness.
2) An abnormal EKG or abnormal stress test.
3) A catastrophe like heart attack or sudden cardiac death.

By this equation, the American Heart Association (AHA) estimates that 36% of American men and women have coronary disease.

However, we say the number is more like 48%. That's the number we arrive at when we ask: How many men and women have CT heart scan scores above zero?

The difference is the Detection Gap. Though only around 12%, it amounts to millions of people. The problem is that, by the conventional approach to detection of heart disease, you often don't know you have it until you're lying on a hospital gurney being wheeled off to a major procedure. Or your friends, family or neighbors find your body.

If heart disease is detected by a CT heart scan, it tends to be early, before catastrophe strikes. You can use tools like niacin, vitamin D, flaxseed, etc., all the components of the Track Your Plaque approach.

If heart disease is detected by waiting for the appearance of symptoms, then a stress test (usually nuclear) is followed by a heart catheterization, stents, bypass, etc. So there's more than a Detection Gap. There's also a difference in the sorts of therapies chosen. There's certainly a difference in cost.

In my view, there is no rational reason not to close the Detection Gap. While CT heart scan scores aren't perfect, they're damn close. The Detection Gap could be closed to around 2%. We'd also save billions of dollars.

Apoprotein B on VAP

We've just received an announcement that, if your Vertical Auto Profile lipoprotein test (Atherotech) is provided through the national Quest laboratories (a large national laboratory company), they will include an apoprotein B.

This represents an improvement over the previous "direct LDL," a measured LDL cholesterol. Recall that standard lipid panels obtained in hospitals and doctors' offices is a calculated LDL, based on the 40-some year old Friedewald calculation. In my view, the Friedewald calculated LDL is a dinosaur that is virtually useless and needs to be retired.

Direct, or measured, LDL is a slight improvement. It removes some of the inaccuracy introduced by the assumptions built into the calculated value.

Apoprotein B (also called apoprotein B100) is yet another improvement. Apo B's have been available for years, but was not provided on the VAP. The Atherotech people have done a good job of making VAP more broadly available through "drawing stations" and proponents like Life Extension. Adding an ApoB is a favorable development, since it incorporates the risk of other ApoB-containing particles, like VLDL, IDL, and Lp(a). Several studies like the Quebec Cardiovascular Study have shown that ApoB is a superior predictor of heart disease compared to calculated LDL.

I still believe that the gold standard for assessing risk from an LDL standpoint is the LDL particle number along with the other measures provided by the NMR assay (Liposcience). However, the addition of the ApoB to VAP adds greater confidence to the measures provided by this technique. Those of you who rely on the VAP assay provided by Quest for your Track Your Plaque program for control of CT heart scan scores therefore have access to this improved panel.
