Dr. Bill Blanchet: A ray of sunshine

Another heated discussion is ongoing at The Heart.org, this one about Tim Russert's untimely death: Media mulls Russert's death as cardiologists weigh in

Although I posted a couple of brief comments there, I quickly lost patience with the tone of many of the other respondents. Should you choose to read the comments, you will see that many still cling to old notions like heart attack is inevitable, defibrillators should be more widely available, "vulnerable" plaques cannot be identified before heart attacks, etc.

I quickly lose patience with this sort of outdated rhetoric. However, our good friend, Dr. Bill Blanchet of Boulder, Colorado, has a far stronger stomach for this than I do.

Here, a sample of his wonderfully persuasive comments:


Heart disease cannot be stopped but we can certainly do better!

Goals we must achieve if we hope to solve the Rube Goldberg of coronary disease:

1. Find something more reliable than Framingham risk factors to determine who is at risk. Framingham risk factors are wrong more often than they are right. If you are comfortable treating 40% of the patients destined to have heart attacks, continue to rely on “traditional” risk factors only.

2. Treat to new standards beyond NCEP/ATP-III. These accepted standards prevent at best 40% of heart attacks in patients treated. This is unacceptable, and arguably why Tim is dead today! Why prevention protocols emphasize LDL and more or less ignore HDL, triglycerides and underemphasize blood pressure eludes me.

3. Motivate patients to participate in coronary prevention. Saying “you need to get exercise and lose weight” is not adequate motivation, it hasn't worked to date and probably won't work tomorrow. If you are satisfied saying it is "the patient's fault for not listening to me" so be it, that excuse doesn't work for me!

Currently “good results” consist of being able to convince 50% of patients at risk by traditional risk factors to participate in prevention and hopefully 30% will be treated to goal. Of those treated to goal, 60% of the heart attacks will still happen anyway. Mathematically we can hope to prevent <10% of heart attacks with this approach!

I have personally found a solution to this dilemma. It goes like this:

1. EBT-CAC [electron-beam tomography coronary artery calcium] is the most reliable predictor of coronary events period, the end! Anyone who disagrees has not objectively read the literature. The only test more predictive than the initial calcium score is the follow up score 12 to 36 months later. EBT predicted Tim Russert’s event 10 years before it happened; passing his stress test gave him inappropriate reassurance 2 months before he died. If only Tim had the benefit of a second EBT sometime over the last 10 years he and his doctor would have known that what they were doing was insufficient and improvements could have been made.

2. I treat to the standard of stable calcified plaque by EBT (<15% annualized progression, preferably <1% annualized progression). This correlates with a very low incidence of coronary events. Even the ACC/AHA 2007 position paper agrees with this. This is accomplished with aspirin, omega-3 fatty acids, diet, exercise, weight control, smoking cessation, treatment of sleep apnea, stress reduction, control of HDL, triglycerides and LDL cholesterol and excellent control of BP and insulin resistance plus the recent addition of vit D-3. Meeting an LDL goal of 70 is easy but prevents only a minority of events, treating to the goal of stable CAC by EBT is a challenge but when achieved, the reward is near elimination of heart attacks and ischemic strokes. This has indeed been my personal experience!

3. A picture of plaque in the coronary artery is a monumental motivator for patients to get on board to make things better. The demonstration of progression of that plaque despite our initial therapies gets all but a few suicidal patients interested in doing a better job. I think that similar motivational results can be had with carotid imaging; the difference is that CAC by EBT is clinically validated as being a much stronger predictor of events with progression and non-events with stability than any ultrasound test including IVUS.



Wow! I couldn't have said it better.

Sadly, I doubt even Dr. Blanchet's persuasive words will do much to convince my colleagues on this forum. And the cardiologists on this forum are likely among the more inquisitive and open-minded. The ones stuck in the cath lab day and night, or implanting defibrillators, are even less inclined to entertain such conversations.

While I admire Dr. Blanchet's energy for continuing to argue with my colleagues, the lesson I take is: Take charge of health yourself. If you wait for your doctor to do it for you, you could be in the same situation as poor Tim Russert. This is an age when your physician should facilitate your success, not prevent it or leave you wallowing in ignorance.

The Russert Protocol at work

Without a concerted effort at prevention, heart scan scores (coronary calcium scores) grow like weeds. The average rate of growth is 30% per year.

Keith is an illustrative case. At age 39, Keith's heart scan score was 29, in the 99th percentile due to his young age. (In other words, young people before age 40 have no business having plaque. If they do, it's bad.)

True to conventional practice, Keith's doctor prescribed a cholesterol drug (Zocor), asked him to take a baby aspirin, and prescribed a blood pressure medicine. He asked Keith to cut the fat in his diet. His doctor even exceeded conventional (ATP-III) LDL cholesterol treatment targets.

Keith, an intelligent and motivated businessman, happily complied with his doctor's instructions. Eighteen months later, a 2nd heart scan showed a score of 68, representing an increase of 135%, or 76% per year.

This is the very same approach that the late Mr. Tim Russert's doctors employed: treat (calculated) LDL cholesterol with a statin drug, treat high blood pressure, reduce saturated fat, take aspirin. It was a miserable failure in Keith, whose plaque continued to grow at a frightening rate of 76% per year. It was also an obvious failure in poor Tim Russert.

Further investigation in Keith uncovered:

--Severe small LDL--80% of all LDL was small (despite a favorable HDL of 58 mg/dl)
--Measured LDL particle number (NMR) showed that "true" LDL was actually about 60 mg/dl higher than suggested by the crude calculated LDL
--An after-eating (postprandial) disorder (IDL)
--A pre-diabetic blood sugar and insulin
--Severe vitamin D deficiency
--Very low testosterone

All these patterns were present despite the steps Keith and his doctor had instituted. It's no wonder his plaque was undergoing explosive growth.

The conventional approach to coronary disease prevention is inadequate, more often than not a mindless adherence to one-size-fits-all template crafted to a great degree by drug industry interests and "experts" who often stand at arm's length from real live patients.

Keith's "residual" abnormalities are all readily correctable. He has since made dramatic improvements in all parameters. Among the strategies used is a wheat- and cornstarch-free diet that resulted in 12 lbs lost within the first few weeks of effort.

If you are on the "Russert Protocol," have a serious conversation with your doctor about the continued advisability of remaining on this half-assed approach to heart disease. Or, consider finding another doctor.

Petition to the National Institutes of Health

A petition to the National Institutes of Health (NIH) is being circulated in response to the mis-statement made in an NIH-sponsored study, ACCORD.

The ACCORD Trial included over 10,000 type II diabetics and compared an intensive, multiple-medication group to achieve a target HbA1c of <6.0%, with a less intensively treated group with a target HbA1c of 7-7.9%. (HBA1c is a long-term measure of glucose, averaging approximately the last 3 months glucose levels.) To the lead investigators' surprise, the intensively treated group experienced more death and heart attack than the less intensive group. The conclusion suggested that intensive management of diabetes may not be a desirable endpoint and may result in greater risk for adverse events.

The petitioners argue that the problem was not with intensive glucose control per se, but the use of multiple side-effect-generating medications. Unfortunately, the ACCORD conclusions give the impression that loose control over blood sugar may be desirable.

The petition originates from the Nutrition and Metabolism Society, a non-profit organization seeking to promote carbohydrate restriction.


The petition reads:

National Institute of Health re: the ACCORD Diabetes Study: "Intensively targeting blood sugar to near-normal levels ... increases risk of death. "

This statement is untrue. This study lowered blood glucose levels only by aggressive drug treatment.

Preventative measures and proven non-drug treatments are being ignored by the NIH, ADA and many other governing agencies.

There is abundant scientific evidence proving a carbohydrate restricted diet can be as effective as drugs in lowering blood glucose levels safely. Many times diet is more effective than medication in controlling diabetes - all without side effects or increased risk of death.

I ask that the NIH publicly retract the above statement. It is misleading the public.

I also request that the NIH acknowledge the existing science and fund more research by the experts who have experience with carbohydrate restriction as a means of treatment for diabetes.

For more info, or to help people with diabetes, please e-mail info@nmsociety.org .

Thank you.




I added my comment:

In my preventive cardiology practice, I have been employing strict carbohydrate restriction in both diabetics and non-diabetics. This results in dramatic improvement in lipids and lipoprotein abnormalities, substantial weight loss, and improved insulin sensitivity. This experience has been entirely different from the heart disease-causing and diabetes-causing low-fat diets that I used for years.

I have a substantial number of diabetics who have been to reduce their reliance on prescription medication for diabetes or even eliminate them. In my experience, the power of carbohydrate-restricted diets is profound.

However, better clinical data to further validate this approach is needed, particularly as diabetes and pre-diabetes is surging in prevalence. I ask that more funding to further explore and validate this research be made available if we are to have greater success on a broader basis.

Wheat withdrawal

It happens in the hospital every so often: A clean-cut, law-abiding person is hospitalized for, say, pneumonia, kidney stones, knee surgery, etc.

Everything's fine until . . . they're running down the hospital hallway stark naked, screaming about snakes on the wall, accusing nurses of trying to kill him, all while yanking out IV's and monitor patches.

It's called alcohol withdrawal. Alcohol withdrawal can range from tremulousness and sweatiness, all the way to delirium tremens, the full-blown form that leads to disorientation, seizures, fever, even death. Withdrawal can also be associated with a number of chronically used agents, such as sedatives/sleeping pills, pain medication/opiates, among others.

How about wheat?

I wouldn't have believed it, but after witnessing this effect countless times, I am convinced there is such a phenomenon: Wheat withdrawal.

You'll recognize it in someone who previously ate bread and other wheat flour-containing products freely, then eliminates them. This is followed by extreme cravings, usually for bread, cookies, or cake; profound fatigue; shakiness; mental fogginess; blue moods. The syndrome can last for up to one week.

Then, bam! Sufferers of wheat withdrawal report mental clarity superior to their wheat-crazed days, improved energy, decreased appetite and cravings, heightened mood, and, of course, fantastic drops in weight.

Why would removal of wheat from the diet trigger a withdrawal phenomenon? I can only speculate, but I believe that at least part of this response is due to a physical conversion from a glycogen (sugar)-burning metabolism to that of a fatty acid (fat mobilizing) metabolism. People who lived in the up-and-down cycle of craving and eating wheat constantly fed the sugar furnace for years and are enzymatically impaired in fat burning; they've been growing fat stores. Eliminating wheat deprives the body of this easy source of glycogen, forcing it to mobilize fatty acids in the fatty tissues. Sluggish at first, people feel fatigue, mental fogginess, etc. Once the enzymatic capacity for fat mobilization revs up, then these feelings dissipate.

Could it also relate to the opioid sequences apparently present in wheat? I wasn't even aware of this fact until a reader of The Heart Scan Blog, Anne, left this comment:

Wheat protein contains a number of opiod peptides which can be released during digestion. Some of these are thought to affect the central and peripheral nervous systems.

When I gave up gluten, I felt much worse for a few days. This is a very common reaction in those who stop eating gluten cold turkey.


Dr. BG provides a fascinating commentary on the addictive/opioid aspect of wheat addictions in her Animal Pharm Blog.

Whatever the mechanism, I believe it is a real phenomenon. It can, at times, be so overwhelming that about 20% of people who try to eliminate wheat find they are simply unable to do it without being incapacitated. Of course, that might be a lesson in itself: If withdrawal is so profound, it hints that there must be something very peculiar going on in the first place.

The Big Squeeze

Some colleagues of mine brought this scary phenomenon to my attention last evening.

As insurance and Medicare reimbursement to doctors and hospitals fall (Medicare is enacting a series of substantial cuts, which will be followed by the private health insurers), you would expect the use of hospital procedures to drop. Makes sense, right? Less money paid per procedure, less incentive to do them.

Unfortunately, that's not how it's playing out in the real world. Your neighborhood interventional cardiologist or cardiothoracic surgeon is accustomed to a level of income and lifestyle. That lifestyle is now threatened by shrinking reimbursement. True to the Law of Unintended Consequences, rather than reducing use of procedures, diminishing procedural fees are prompting a good number of practitioners to do more.

In other words, if each heart catheterization pays less, why not do more of them, along with more stents, pacemakers, defibrillators, and the like? If four heart catheterizations per day pays less, why not do five to make up the difference?

Voila! Income protected. Of course, it comes at the cost of more work. But I will give one thing to my colleageus: They are a generally hard-working bunch who rarely balk at 12-16 hours days in the hospital.

How do you do more procedures? Easy. Just lower the bar on who to do a procedure on. Use more aggressive criteria for pacemaker implantation. Interpret the always-fuzzy nuclear stress tests weighed more towards abnormal. Use scare tactics: "You never know--that chest pain could be the last warning you're going to have!" Because the criteria for performing procedures is "soft" in the real world, it is easy to bend the criteria any way you want.

It's too early to measure the full impact of this unintended consequence of reduced reimbursement. But don't allow yourself to become a casualty in the reimbursement war. Remain vigilant. Recognize that, despite the fuzziness at the edges, there are still rational reasons for performing heart procedures. Always be armed with information and the right questions. Never submit unquestioningly or without satisfactory answers to your questions.

Tim Russert's heart scan score 210. . .in 1998

Despite the media blathering over how Mr. Russert's tragic death from heart attack could not have been predicted, it turns out that he had undergone a heart scan several years ago.

A New York Times article, A Search for Answers in Russert’s Death, reported:

Given the great strides that have been made in preventing and treating heart disease, what explains Tim Russert’s sudden death last week at 58 from a heart attack?

The answer, at least in part, is that although doctors knew that Mr. Russert, the longtime moderator of “Meet the Press” on NBC, had coronary artery disease and were treating him for it, they did not realize how severe the disease was because he did not have chest pain or other telltale symptoms that would have justified the kind of invasive tests needed to make a definitive diagnosis. In that sense, his case was sadly typical: more than 50 percent of all men who die of coronary heart disease have no previous symptoms, the American Heart Association says.

It is not clear whether Mr. Russert’s death could have been prevented. He was doing nearly all he could to lower his risk. He took blood pressure pills and a statin drug to control his cholesterol, he worked out every day on an exercise bike, and he was trying to lose weight, his doctors said on Monday. And still it was not enough.

“What is surprising,” Dr. Newman said, “is that the severity of the anatomical findings would not be predicted from his clinical situation, the absence of symptoms and his performing at a very high level of exercise.”


Buried deeper in this article, the fact that Mr. Russert had a heart scan score of 210 in 1998 is revealed.

That bit of information is damning. Readers of The Heart Scan Blog know that heart scan scores are expected to grow at a rate of 30% per year. This would put Mr. Russert's heart scan score at 2895 in 2008. But the two doctors providing care for Mr. Russert were advising the conventional treatments: prescribing cholesterol drugs, blood pressure medication, managing blood sugar, and doing periodic stress tests.

Conventional efforts usually slow the progression of heart scan scores to 14-24% per year. Let's assume the rate of increase was only 14% per year. That would put Mr. Russert's 2008 score at 779.

A simple calculation from known information in 1998 clearly, obviously, and inarguably predicted his death. Recall that heart scan scores of 1000 or greater are associated with annual--ANNUAL--risk for heart attack and death of 20-25% if no preventive action is taken. The meager prevention efforts taken by Mr. Russert's doctors did indeed reduce risk modestly, but it did not eliminate risk.

We know that growing plaque is active plaque. Active plaque means rupture-prone plaque. Rupture prone plaque means continuing risk for heart attack and death. Heart attack and death means the approach used in Mr. Russert was a miserable failure.

While the press blathers on about how heart disease is a tragedy, as Mr. Russert's doctors squirm under the fear of criticism, the answers have been right here all alone. It sometimes takes a reminder like Mr. Russert's tragic passing to remind us that tracking plaque is a enormously useful, potentially lifesaving approach to coronary heart disease.

Who needs to go next? Matt Lauer, Oprah, Jay Leno, some other media personality? Someone close to you? Can this all happen right beneath the nose of your doctor, even your cardiologist?

I don't need to remind readers of The Heart Scan Blog that heart disease is 1) measurable, 2) trackable, 3) predictable. Mr. Russert's future was clear as long ago as 1998. Every year that passed, his future became clearer and clearer, yet his doctors fumbled miserably.

Another failure of conventional cardiac care


Though Tim Russert was widely known and respected for his political commentary, he will likely be better remembered as an example of the gross shortcomings of the conventional approach to heart disease.

Let's face it:

Standard heart disease prevention efforts are a miserable failure.

A Track Your Plaque member brought this interview of Mr. Russert's doctor to my attention.

It appears that his doctor did all the correct conventional things. You know what became of it. In the eyes of the public and of any attorney, or even of my colleagues, no wrong was committed. The blame does not lie with Mr. Russert's hapless doctor. The blame lies on the system that endorses procedures, prescription medications, the blind adherence to dogma dictated by the pharmaceutical industry and FDA, along with a prevailing philosophy of preferring the management of catastrophes to preventing them. Dr. Newman's idea of a solution: Making an automatic defibrillator (AED) more widely available (!!!).

How long does this sort of idiocy have to go on? How many people have to die before the system uses the tools that are already available, tools that could have prevented this tragedy and many more like it?

If you and your doctor subscribe to the program that the unfortunate Mr. Russert was prescribed and the brainwashing, unthinking nonsense that his doctor follows, you are a fool. Shame on you. You therefore likely subscribe to the same variety of marketing BS that issues from food manufacturers about Cheerios, whole grains, and low-fat diets.

Get with the program. Sadly, Mr. Russert is not the first, he's not the last. The tragedies of conventional advice that line the pockets of drug and food manufacturers number in the millions. We're not talking about some obscure, rare disease. We're talking about the number one cause of death in both males and females nationwide.

I deeply wish this message could have reached Mr. Russert before his untimely death. We could all look forward to another Sunday morning with his usual incisive, unforgiving probing of the day's political figures.

Tribute to Tim Russert

The sudden passing of news giant, Tim Russert, yesterday of sudden cardiac death struck a blow to American consciousness.

Perhaps his hard-hitting interviewing style, while making guests squirm, made him seem invincible. But, of course, none of us is invincible. We are all vulnerable to this disease.

We should not allow Mr. Russert's tragic death to occur without taking some lessons. The media have already resorted to interviewing prominent doctors for their opinion.


Douglas Zipes, M.D., former President of the American College of Cardiology,was quoted in the media:

"An automated external defibrillator (AED) could have been a life-saver. AEDs should be as common as fire extinguishers."

This is typical sleight-of-hand, medicine-is-too-complex-for-the-public-to-understand sort of rhetoric that is surely to issue from the conventionally-thinking medical people and the press. Instead, let's cut the BS and learn the real lessons from Mr. Russert's needless death.

It is virtually certain that:

--Mr. Russert ruptured an existing coronary atherosclerotic plaque, prompting rhythm instability, or ventricular fibrillation.

--Making automatic external defibrillators (AED) available might have Band-Aided the ventricular fibrillation, but it would not have stopped the heart attack that triggered it.

--Though full details of Mr. Russert's health program have not been made available, it is quite likely that he was prescribed the usual half-witted and barely effective panoply of "prevention": aspirin, statin drug, anti-hypertensive medication. Readers of The Heart Scan Blog and members of Track Your Plaque know that this conventional approach is as effective as aspirin for a fractured hip.

--It is highly unlikely that all causes of Mr. Russert's heart disease had been identified--did he have small LDL (it's certain he did, given his body habitus of generous tummy), Lp(a), low HDL, pre-diabetic patterns, inflammatory abnormalities, vitamin D deficiency, etc.? You can be sure little or none of this had been addressed. Was he even taking simple fish oil that reduces the likelihood of sudden cardiac death by 45%?

--Far more could have been done to have prevented Mr. Russert's needless death. And I don't mean the idiocy of making AED's available in office buildings. I'm talking about preventing the rupture of atherosclerotic plaque in the first place.

Far more can be done to prevent future similar deaths among all of us.

Our jobs are to use the tragic death of Mr. Russert to help those around us learn that heart disease is identifiable and preventable. Though Mr. Russert did not stand for BS in his political commentary, he sadly probably received it in his health advice. Don't let this happen to you or those around you.

Why do skinny people get heart disease?

There's no doubt about it: The majority of people with heart disease are overweight. They may not be grotesquely overweight, just a few pounds over. But weight plays a crucial role in activating numerous factors that heighten risk for heart disease.

Excess weight reduces HDL cholesterol, raises triglycerides, increases small LDL (enormously), fans the fires of inflammatory responses (CRP, IL-6, TNF-alpha, etc.) raises blood pressure, increases resistance to insulin and raises blood sugar. Overweight people tend to be less physically active, may develop diseases of obesity like sleep apnea, and on and on. You've heard this all before.

But why do slender people develop heart disease? If we can't blame weight, what is to blame? By slender, I mean body mass index (BMI) of <25. (Yes, I know there are other ways, better ways, to gauge healthy weight. But, for simplicity, I'll use BMI.) Let's put aside the two obvious causes of heart disease, cigarette smoking and Type I diabetes. (I'd be shocked if any cigarette smokers read this blog.)

Slender people develop heart disease because:

1) They have lipoprotein(a)--The big, big neglected risk factor. In fact, the Lp(a) genotype is, in my casual observation, associated with a slender phenotype (genotypic expression). The prototypical example that makes headlines is the marathon runner--slender and superbly fit, but develops heart disease anyway. People wax on about the uncertainties of exercise and fitness when they hear about Jim Fixx and Alberto Salazar. But one factor would explain it all: Lp(a).

2) The murky category of the normal weight obesity. These people are generally recognizable by their flaccid tummies despite falling into a favorable BMI <25. Small LDL is the standout red flag in these people.

3) They were previously overweight but lost it.

4) They were former smokers.

5) Vitamin D deficiency--Deficiency of vitamin D is important for everyone's health. But there appears to be some people for whom it is the dominant risk. I believe that one of our great Track Your Plaque success stories, Neal, falls into this group. Some people who are vitamin D deficient develop colon cancer, others develop diabetes, others develop osteoporosis or multiple sclerosis, while others develop coronary heart disease and plaque. The likely reason for the varied expression is variation in vitamin D receptor genotypes (VDR genotypes).

6) The murkiest of all: Hypertension genotypic variants. This is a poorly sorted-out category, and one principally based on my observations along with scattered observations in such things as variations in the angiotensin converting enzyme genotypes. But I am convinced that there is a small percentage of slender people who show variation in some genetic type that predisposes to hypertension and heart disease. They also show a propensity towards enlargement of the thoracic aorta. This group is also among the most difficult to control in the Track Your Plaque approach, i.e., they have difficulty slowing or stopping the growth of heart scan scores. While blood pressure control in this group is important, it does not seem to remove the excess source of risk.

So, yes, being slender does put you into a lower risk for heart disease category. But it does not mean you are immune.

You can also be an overweight person who still harbors some of the features of the slender--you're an overweight slender person. The above list can still therefore apply.

Cardiology Confidential


Okay, so it's a shameless knockoff of chef Anthony Bourdain's titillating Kitchen Confidential.

But the confidences that I've heard whispered in the corridors of health involve something more provocative than how your food was prepared. Any service for humans performed by other humans is subject to the idiosyncrasies and weaknesses of human behavior. That's just life.

In healthcare for your heart, the consequences can be more profound than eating three day old fish on Monday's dinner menu.

Over my 15 years practicing cardiology in a variety of settings in three different cities, I've witnessed just about everything from shocking to sublime. Some of it speaks to the extraordinary commitment of people in healthcare, the unexpected courage people show in the midst of illness, the devotion of family in difficult times. It can also speak of mewling, sobbing carryings-on over the most minor conditions, the meanness that emerges when people are frightened, the vultures circling just waiting for Grandpa to kick the bucket and leave his will declaring the spoils.

For the most part, my cardiology colleagues are a hard-working bunch committed to . . . Uh oh. I was going to say "Saving lives, preserving health." But that's not true. Once upon a time, it was true for many of my colleagues, often revealed over $2-a-pitcher beer-softened, "we're going to save people" conversations in medical school. Ahhh, medical school. I remember walking along the street alongside my medical school in St. Louis, bursting with pride and a sense of purpose.

But, for many of us, something sours our purpose through the years. Maybe it's the smell of money, maybe it's the series of distasteful experiences that show that healthcare providers are, in the midst of health crises, the innocent recipients of anger, frustration, disappointment.

Whatever the genesis, the stage is set for an imperfect scenario that pits healthcare provider against patient in a less-than-perfect system.

This would read as a mindless rant if it wasn't based on such pervasive and pravalent truths, tales of the flawed deliverers of healthcare driven by motives less lofty than "saving people."

Take Dr. S, a doctor who performs a large number of procedures on patients. I'm told he is very capable. He manages an extraordinary amount of heart work--in between jail time for wife beating and Medicare fraud.

Or Dr. C, well-known in the region for his procedural talents, also. Usually acerbic and freely-swearing, he opens up engagingly when drinking--which is most of the time. Paradoxically, as is true for some serious drinkers, he works more effectively while intoxicated.

Or Dr. ST, who proudly admitted to me one evening over dinner that he has accepted 6-figure payments from medical device companies on a number of occasions to use their products.

Or the manic ups and downs of Dr. J, who refers just about every patient he sees for emergency bypass surgery when in his down phase, mangles coronary arteries in daring angioplasties during his up phase.

How about 310-lb Dr. P, who hounds her patients about indulgent lifestyles? That would be excusable as innocent lack of self-insight if it weren't for her propensity to use heart procedures on patients as punishment. "I have no choice but to take you to the hospital."

Dr. M. manages to maintain the appearance of straight-and-narrow during the day, all the way to attending church twice a week with his children. His daytime persona effectively covers up his frequent visits to prostitutes.


We are ALL flawed. My colleagues are no different. But some circumstances cultivate the flaws, fertilize corruptibility, reward it. Such has become the state of affairs in healthcare for heart disease. Why? Is it the excessive potential for money-making that existed until recently? Is there something about the save-the-day mentality of heart disease that attracts imperfect personalities looking for the adrenaline-charged thrill but morphs over time into near-psychopathic lives?

It's not the end of the world. The fact that my colleagues' behavior has reached such extravagant lows signals a bottom: things are about to change.

In the meantime, let me tell you a few more secrets . . .

Are there any alternatives to niacin?

In the Track Your Plaque program, we tend to rely a great deal on niacin. When used properly, 90-95% of people will do just fine and achieve their lipid and lipoprotein goals with the help of niacin, along with their other efforts.

Unfortunately, around 5% of people simply can't take niacin without intolerable "hot flush" effects, or occasionally excessive skin sensitivity--itching, burning, etc.

Why does this happen? These 5% tend to be "rapid metabolizers" of niacin, i.e. they convert niacin (nicotinic acid, or vitamin B3) into a metabolite called nicotinuric acid. Nicotinuric acid is the compound responsible for the skin flush. Most people can slow or reduce the effects of nicotinuric acid by:

--Taking niacin with dinner, so that food slow tablet dissolution.

--Taking with plenty of water. Two 8-12 oz glasses usually eliminates the flush entirely in most people.

--Taking with an uncoated 325 mg tablet of aspirin in the first few weeks or months. Eventually, you will need to revert back to a better stomach tolerated dose of 81 mg, preferably enteric coated. But a full 325 mg uncoated can really help in the beginning, or when you have any niacin dose increases, e.g., 500 mg to 1000 mg.

But even with these very effective strategies, some people still struggle. That's when the question arises: Are there any alternatives to niacin?

Well, it depends on why niacin is being used. If you and your doctor are using niacin for:

Raising HDL--Then weight loss to your ideal weight; reduction of processed carbohydrates, especially wheat products; avoidance of hydrogenated ("trans") fats; a glass or two of red wine per day; dark chocolates (make sure first ingredient is chocolate or cocoa, not sugar), 40 gm per day; fish oil; exercise; other prescription agents (fibrates like Tricor; TZD agents for diabetes; cilostazol (Pletal)). Niacin is by far the most effective agent of all, but, if you're intolerant, raising HDL is still possible through a multi-faceted effort.

Reduction of small LDL--The list of effective strategies is the same as for raising HDL, but add raw almonds (1/4-1/2 cup per day), oat bran and other beta-glucan rich foods like oatmeal. Reduction of processed carbohydrates is especially important to reduce small LDL.

Reduction of Lipoprotein(a)--This is a tricky one. For men, testosterone and DHEA are effective alternatives; for women, estrogen and perhaps DHEA. Hormonal preparations of testosterone and estrogen are stricly prescription; DHEA is OTC. I have not seen the outsized benefits on lipoprotein(a) claimed by Rath et al by using high-dose vitamin C, lysine, and profile, unfortunately. We are clearly in need of better alternatives to treat this difficult and high-risk disorder.

Reduction of triglycerides/VLDL/IDL--I lump these three together since they all respond together. If you're niacin intolerant, maximixing your fish oil can be crucial for reduction of these patterns using doses above the usual starting 4000 mg per day (providing 1200 mg EPA+DHA). Reduction of processed carbohydrates, eimination of processed foods that contain high-fructose corn syrup, and weight loss to ideal weight are also very effective. "Soft" strategies with modest effects include green tea (>6 cups per day) or theaflavin 600-900 mg/day; raw nuts like almonds, walnuts, and pecans; exercise; soy protein.

Reduction of LDL--Lots of alternatives here including oat bran (3 tbsp per day), ground flaxseed (3 tbsp per day), soy protein (25 grams per day), Benecol butter substitute (for stanol esters), soluble fibers like pectin, psyllium, glucomannan; raw nuts like almonds, walnuts, and pecans.

In future, should torcetrapib become available (by prescription), this will add to our available tools for these areas when niacin can't be used. Until now, the alternatives to niacin depend on what you and your doctor are trying to achieve. In the vast majority of cases, HDL, small LDL, triglyceride, etc. goals for heart scan score control can be achieved, even when niacin is not well tolerated.

Is flaxseed oil a substitute for fish oil?


This question comes up so frequently that it's worth going over.

Flaxseed oil is a wonderful oil rich in linolenic acid, which may provide health benefits all by itself. Some authorities have speculated that the substantial reduction in heart attack seen in the Lyon Heart Study, the study that demonstrated the healthy power of the Mediterranean diet, is due to linolenic acid.

Flaxseed oil is also rich in monounsaturates and low in saturates, both desirable qualities. Of course, I'm talking here about flaxseed oil, to be distinguished from flaxseed , which are the intact seeds. The seeds themselves also contain the same oils, but contain other components, specifically lignan, a plant fiber with suspected health benefits like reduction in cancer risk.

Despite all flaxseed oil's wonderful properties, it is definitely not a substitute for fish oil. Why do we use fish oil for our coronary plaque control program (trying to reduce your heart scan score)? Several reasons. Fish oil:

--Dramatically reduces triglycerides, usually by 50% or more.
--Dramatically reduces specific lipoprotein classes like VLDL
--Dramatatically reduces, often eliminates, abnormal postprandial (after-eating) lipoprotein patterns, like IDL (intermediate-density lipoprotein)
--Has been conclusively shown to reduce risk of heart attack and death from heart attack (GISSI Prevenzione Trial).
--Has been shwon to reduce risk of stroke.
--Modifies blood clotting parameters, particularly a 20% reduction in fibrinogen.

Flaxseed oil, or linolenic acid concentrate for that matter, do not accomplish any of these effects, all crucial if you are to gain control over your coronary plaque.

Flaxseed oil and flaxseed remain wonderful nutritional agents for their own reasons. But they will not substitute for fish oil in your program. Only fish oil--the real thing--does the job.

If you have coronary artery disease . . . do you know why?

This conversation is aimed primarily at non-followers of the Track Your Plaque program, because if you were a follower, you’d already know the answer!

I saw a woman in the hospital today. She’d just survived her second heart attack one week earlier. At 51 years old, she was understandably shaken, perhaps terrified. She felt that her future was uncertain and, in fact, had discussed with her husband what he should do to prepare for a future without her.

One week earlier, she’d received three stents that successfully aborted her heart attack. But, as is always the case, the modest delays of ambulance transport, the emergency room preliminaries, then of mobilizing an available cardiologist and catheterization laboratory team, totaled nearly two hours before her stent procedure. Inevitably, a moderate amount of damage had been done to her heart.

Her first “event” had been very similar: very little warning, then 911 and the flurry of activity. Both times, the cardiologists (two different physicians) complimented the patient on her prompt action. Both also called her heart attacks “close calls”.

She defied the odds with two near-death events. So, when I met her a week after her last heart attack, I asked an obvious question: “Has anyone told you why you’re having these heart attacks?”

She looked completely puzzled at first. She then said, “No, not really. I just assumed it was genetic. My mother went through the same thing when she was my age. But she didn’t get as far as I have, since they didn’t have these procedures back then.”

To me, this seems inexcusable: This woman had experienced two brushes with death and no doctor had established a cause. Could this woman’s belief be true, that it’s just genetic?

While there are, indeed, genetic causes for heart disease, the vast majority of these genetic causes are 1) identifiable, and 2) correctable. Genetic does not necessarily mean hopeless. It just means that the usual equation of heart disease risk management (heart disease = LDL cholesterol = need for Lipitor) has limited value. It would be like giving penicillin to people for any and all infections. It will work occasionally, but it will fail miserably in a great many cases. Treating LDL cholesterol with statin drugs is just like that.

Perhaps this woman has lipoprotein(a), a serious genetic trait that predicts heart disease at a young age and is largely unaffected by statin drugs. Or, she may have a severe excess of small LDL, only partially suppressed by statins. If she has the combined pattern of lipoprotein(a) and small LDL, that means she has two statin-unresponsive and significant genetic traits. But they respond to niacin, specific nutritional strategies, and several other agents.

The message: If you have coronary disease, you need to insist on knowing why. “It’s genetic” is not an acceptable answer. “There’s no proof of any heart disease causes beyond cholesterol” is also nonsense. “Everyone gets heart disease, or “hardening of the arteries”, eventually. You just got it a little before everyone else” is also patently ridiculous.

Identifying the causes of your coronary disease (or coronary plaque if you’ve had a CT heart scan) is the first step in developing a program of treatment that provides you with control over this disease.

Have you tried inulin yet?

If you haven't yet tried it to facilitate weight loss, it's really worth giving the new inulin-containing product, Fiber Choice "Weight Management", a try.

Recall (from a prior Heart Scan Blog) that inulin is a vegetable-based fiber found in celery, green peppers, etc. that, when exposed to water, expands to many times original volume. This simple phenomenon yields satiety--a feeling of fullness.


The manufacturer of the product has also added green tea, which has been shown in two small clinical studies to enhance weight loss, though by a different route.

We've been advising patients to chew two of the strawberry flavored tablets one hour before every meal (or with breakfast if you eat immediately in the morning). You'll be satisfied with less food and you'll experience less intense food cravings.

Though no one so far has achieved a huge drop in weight, it does seem to enhance a slow, gradual weight loss larger than achieved by diet and exercise alone. And it's very safe and inexpensive. If you give it a try to help you lose weight, let us know what kind of results you've obtained.

More on Vitamin D

If you haven't done so already, you should subscribe to Dr. John Cannell's free newsletter on vitamin D issues. His newest issue is available at:

http://www.vitamindcouncil.com/newsletter/2006-aug.shtml

A sign-up to subscribe is available on the same page.

I continue to be shocked and amazed at the prevalence and magnitude of vitamin D deficiency in the people I see every day. It's been a beautiful summer with very little rain. Most days have been in the 70-80 degree range--very comfortable to be outdoors in the sun and getting skin expoxure to activate vitamin D in the skin.

Yet, in the vast majority of people I see, summer blood levels of vitamin D are virtually indistinguishable from winter levels. Both hover around the 30 ng/ml range. Summer levels in Wisconsin people seem to be no more than 10 ng/ml higher than winter levels. This remains true even in people who spend a lot of their day outdoors gardening, walking, etc. wearing shorts and a short-sleeved shirt, i.e. with plenty of skin surface area exposed.

I'm at a loss to explain precisely why. Yes, it is Wisconsin. But a direct sun overhead, 75 degree day should be providing plenty of sun. My suspicious is that a combination of factors are at work: people are not spending as much time outdoors as they claim; they often seek shade; use sunscreen; and they're overweight. (Excess weight decreases vitamin D blood levels dramatically, yet another reason not to get fat!)

Read more about vitamin D by checking out Dr. Cannell's insightful comments on the unfolding vitamin D story. He holds nothing back.

Why not just get "perfect" lipids and call it a day?

What if you achieved the Track Your Plaque lipid targets: LDL cholesterol 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl?

After all, these are pretty stringent standards. Compared to national guidelines (the ATP-III Guidelines of the National Cholesterol Educational Panel), the Track Your Plaque 60-60-60 goals are laughably ambitious. There's a lot of wisdom hidden in those numbers. The triglyceride level of 60, for instance, is a level at which triglycerides become essentially unavailable for formation of triglyceride-containing lipoprotein particles such as small LDL and VLDL.

If you get to the 60-60-60 target, isn't that good enough? What if you just held your values there and went about your business? Will coronary plaque stop growing and will your CT heart scan score stop increasing?

Sometimes it will. But, unfortunately, many times it will not. The experience generated through clinical trials bear this out. Studies like the St. Francis Heart Study and the BELLES Trial both showed that just reducing LDL cholesterol is insufficient to stop plaque growth. Beyond the Track Your Plaque experience, there's no clinical trial experience that shows whether the 60-60-60 approach does any better.

In our experience, achieving 60-60-60 is indeed better than just reducing LDL. That makes sense. Just raising HDL from the average of 42 mg/dl for a male, 52 mg/dl for a woman adds advantage. Compound this with triglyceride reduction from the plaque-creating equation, and you've doubled success.

But there's even more. What if you had hidden patterns not revealed by conventional lipids? How about lipoprotein(a)? Small LDL? Postprandial (after-eating) abnormalities? Hypertensive effects (more common than you think)!

In 2006, stopping the increase in your heart scan score is, for most of us, not just a matter of taking Lipitor or its equivalent and sitting back. For nearly all of us, stopping the progression of your score is a multi-faceted effort.

Hospitals: Then and Now

It's 1920. The hospital in your city is a facility run by nuns or the church. It's a place for the very ill, often without hope of meaningful treatment, but nonetheless a place where surgeries take place, babies are born, the injured and chronically ill can find care. No one has health insurance and there's no Medicare. Everyone pays what they can. The hospital is accustomed to doling out plenty of care without compensation. For that reason, they welcome donations and sometimes will build new additions or other facilities in honor of a major donor.

Volunteeers are common, since the wards are understaffed and generally suffering from a shortage of trained nurses and personnel associated with the church. Drugs, such as they are, are often prepared from basic ingredients in the hospital pharmacy. Product representatives hawking medicines and devices are virtually unheard of.

Though their therapeutic tools are limited, the physicians are a proud group, dedicating their careers to healing. The majority of the medical staff volunteer large portions of their time to care for the poor who come to the hospital with very advanced stages of disease: metastatic tumors, advanced heart failure, debilitating strokes, overwhelming septicemia, etc.

Hospitals are usually governed by a board of clergy and physicians who make decisions on how to apply their limited resources and continually seek charitable donations.


Fast forward to present day: Hospitals are high-tech, professional facilities with lots of skilled people, complicated equipment,and capable of complex procedures. While they still house people with advanced illnesses, the floors are also filled with people with much earlier phases of disease. In general, they do a good job, with quality issues scrutinized by a number of official agencies to police practices, incidence of hospital-related infections, medication errors, care protocols, etc.

The hospital of 2006 is a more more effective place than the hospital of 1920. But its aims and operations are different, also. Though some churches are still involved in hospitals, more and more are owned by publicly-traded companies that answer to shareholders--shareholders who want share value to increase. Though donations are still sought, much of the revenues are obtained by concentrating on profitable, large-ticket procedures. More procedures are often generated by advertising.

Because they operate to generate profits, several hospitals in a single city or region compete with one another. The 21st century has therefore witnessed the phenomenon of hospital-owned physicians: more and more practicing physicians are employees of their hospital. That way, the physician brings all his patients and procedures to his hospital, not to a competitor. The top of the funnel is the primary care physician, who tends to see all disease when it first occurs. The primary care physician then sends the patient to the specialist, who is obliged (by contract) to perform his/her procedure in the hsopital paying their salary.




Representatives from companies manufacturing and selling expensive hospital equipment and drugs are everywhere, falling over themselves to gain attention of the physicians using their equipment and the hospital buyers who make purchasing decisions. Millions of dollars can be transacted with just one sale.

The number of volunteers has dwindled. The poor and uninsured are commonly diverted elsewhere, often to a government-funded, and often second-rate, institution. Hospitals measure success by comparing annual revenues and numbers of major procedures.

The hospital of 2006 is a vastly different place than 1920. If you're expecting charitable treatment, compassion, and selfless care, you're in the wrong century. In 2006, the hospital is a business. You don't expect charitable treatment at Wal-Mart or from your car dealer. Don't expect it from your hospital. They are businesses and you are a customer. Recognize this fact, lose the nostalgia for the hospitals of yesterday, and a lot more will become clear to you.

The dreaded small LDL particle

Brian is a 59-year old landscape architect whose starting CT heart scan score was 276.

Brian's food choices at the start were deplorable: a pound of sausage per week, sometimes more; butter on anything and everything; up to two pounds of cheese per week; hot dogs; etc. His lipoproteins were accordingly just as miserable: low HDL, high triglycerides, excessive (postprandial, or after-eating) IDL. Small LDL was a particularly stand-out pattern, with 95% of all LDL particles in the small category.

Brian made a dramatic turnaround in lifestyle and corrected all of his patterns--except for small LDL. After one year, small LDL still occupied 95% of all LDL particles, even though the quantity of LDL had been reduced. In order to help convince Brian that correction of his small LDL was going to be necessary to achieve control oover coronary plaque, I suggested that he undergo another heart scan. His score: 435, or a 57% increase.

Each day that passes, I gain more and more respect for small LDL as a cause for coronary plaque growth. Conventional thought among lipid experts is that small LDL should no longer be a factor if total LDL (e.g., LDL particle number) is reduced. But our experience suggests otherwise: when small LDL persists, we tend to see continued, sometimes frightening, plaque growth.

I therefore asked Brian to intensify his efforts: additional weight loss off his somewhat prominent abdomen (since visceral fat increases small LDL), further reduce wheat products and processed carbohydrates, increase niacin (to 1500 mg per day), and use more raw almonds and oat bran.

Don't let small LDL get the best of you. It is a nasty, sometimes persistent abnormality that has impressive effects on plaque growth.

Winning Through Intimidation

Do you remember the book, Winning Through Intimidation by author Robert J. Ringer?



In his 1984 bestseller, author Ringer details how to succeed in business by overwhelming clients and competition by appearing hugely successful and powerful. Rather than a business card, he'd hand out an elegant book to represent himself. He'd show up in a limousine to a meeting, even when he could barely afford it. He used these tactics, even when he was a small-fry, in commercial real estate and built a successful business following such techniques.

This reminds me a lot of what happens in conventional medical practice: The large and successful hospitals, filled with trained staff and technology, exude legitimacy and success. How can they possibly be wrong? Such overwhelming know-how and multiple levels of expertise mustbe right!

Let's be grateful that we do have access to such high-tech, capable care. Unfortunately, just as Mr. Ringer used deceptive practices to appear something he wasn't, this is also true in hospitals. Not all physicians have your best interests in mind. Their principal concern is how profitable your care can be for them--can you be persuaded to have your stent, bypass, etc.. After all, look around you: Aren't all this equipment and personnel impressive? Aren't you intimidated?

The patient that most recently drove home this issue for me recently was a smart and capable executive who came in for consultation. He had been told by his internist that a surgery (to replace his aorta, a HUGE procedure) was probably necessary. In my view, it was not--his process was simply not that far progressed. The risks for danger over the next several years was virtually nil. Unfortunately, this man, now confused and worried, sought an opinion from the chief of thoracic surgery (in the usual white coat and with professorial demeanor, I'm sure) in a major metropolitan hospital (in Chicago), who promptly rushed him off to the operating room.

The pathology report, cleverly not mentioned in any other of the hospital documentation, showed what I had suspected: this man had mild disease that wasn't even close to requiring surgery. But, with all that technology, $100,000 or so of costs, chief of surgery who looked the part, etc.--they must be right!

Robert Ringer's concepts only ring too true for hospitals and some of the unscrupulous physicians in practice. Don't allow yourself to be intimidated.

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.

To track small LDL, track blood sugar

Here's a trick I learned after years of fussing over people's small LDL.

To gain better control over small LDL, follow blood sugars (blood glucose).

When you think about it, all the foods that trigger increases in blood sugar also trigger small LDL. Carbohydrates, in general, are the most potent triggers of small LDL. The most offensive among the carbohydrates: foods made with wheat. After wheat, there's foods made with cornstarch, sucrose (table sugar), and the broad categories of "other" carbohydrates, such as oats, barley, quinoa, sorghum, bulghur, etc.

Assessing small LDL requires a full lipoprotein assessment in which small LDL particles are measured (NMR, VAP, GGE). Not the easiest thing to do in the comfort of your kitchen.

However, you can easily and now cheaply check your blood sugar. Because blood sugar parallels small LDL, checking blood sugar can provide insight into how you respond to various foods and know whether glucose/small LDL have been triggered.

Here's how I suggest patients to do it:

1) Purchase an inexpensive blood glucose monitor at a discounter like Walmart or Walgreen's. You can buy them now for about $10. They're even sometimes free with promotional offers. You will also need to purchase lancets and test strips.

2) With a meal in question, check a blood sugar just prior to the meal, then again 60 minutes after finishing the meal. Say, for example, your pre-meal blood sugar is 102 mg/dl. You eat your meal, check it 60 minutes after finishing. Ideally, the postprandial (after-meal) blood sugar is no more than 102 mg/dl, i.e., no higher than pre-meal.

Perhaps you're skeptical that oatmeal in skim milk with walnuts and raisins will do any damage. So you perform this routine with your breakfast. Blood sugar beforehand: 100 mg/dl. Blood sugar 1 hour post: 163 mg/dl--Uh oh, not good for you. And small LDL will be triggered.

This approach is not perfect. It will not, for example, identify "stealth" triggers of blood sugar and small LDL like pasta, for the same reasons that pasta has a misleadingly low glycemic index: sugars are released slowly and not fully evident with the one-hour blood sugar.

Nonetheless, for most foods and meals, tracking your one-hour postprandial blood sugar can provide important insight into your individual susceptibility to sugar and small LDL-triggering effects.

C-reactive protein: Fiction from the drug industry?

C-reactive protein (CRP) is the liver product of inflammatory responses anywhere in the body. If there's an inflamed left knee, CRP will be increased. If viral bronchitis is making you cough, then CRP will be increased.

The argument put forward by the drug industry is that, because CRP indicates underlying inflammation, very low-grade levels that can be measured in the absence of overt inflammation like the sore knee or bronchitis is associated with increased risk for cardiovascular events. There are now many studies that conclusively demonstrate that, the higher the CRP, the greater the cardiovascular risk.

Naturally, any marker of risk is followed by the inevitable study: Do statin drugs reduce the excess cardiovascular risk of excessive CRP?

And, yes, indeed they do. My statin-crazed colleagues rave about the so-called "pleiotropic," or non-lipid, effects of statins. CRP reduction and the reduction of risk associated with CRP result with statin treatment.

But is life really statin vs. placebo, as most statin trials are constructed? Are there strategies that can outdo statins like Crestor for reduction of CRP?

Watch your fish oil labels

A quick quiz:

How much omega-3 fatty acids, EPA + DHA, are in each capsule of fish oil with the composition shown on the label below:





If you said 1340 mg (894 mg + 446 mg), sorry, but you're wrong. There are 670 mg EPA + DHA per capsule.

Did you notice that the composition, or "Supplement Facts," lists the contents of two capsules? Rather than the usual one capsule contents, this product label lists two capsules.

I don't know why some manufacturers or distributors do this. However, I have seen many people tripped up by this kind of labeling, taking half the omega-3 fatty acids they thought they were taking. This can be important when you are trying to obtain a specific dose of EPA + DHA to reduce triglycerides, reduce Lp(a), control abnormal heart rhythms, reduce bipolar mood swings, or other important effects.

I liken this to pulling up to a gas station where the sign says gasoline for $1.25. Wow! Can't beat that! You then find out that it's really $1.25 for a half-gallon, or $2.50 a gallon.

In truth, the labeling is accurate; it's just very easy to not notice the two capsule composition.

Why do I need a prescription for Olava?

Imagine this:





What is OLAVA?

Olava is prescription olive oil. It is the purest, highest concentration of olive oil available.




Why Do I Need a Prescription for OLAVA?

Studies show that olive oil contains essential fatty acids, "good" fats that:
