Statin stupid

If we followed the lead of the pharmaceutical industry and my cardiology colleagues, we would all subscribe to the "statins for all" philosophy. There is now $2 billion of clinical "research" to back up this "evidence-based" practice.

I do not endorse this "statins for all" philosophy. I believe it is a product of the raw profiteering of the pharmaceutical industry, who are adept at recruiting physicians to their cause.

But lost in the confusion of tainted studies and over-the-top media saturation is the fact that there are small groups of people who likely do obtain benefit from statin drugs. They would certainly benefit from better informed scrutiny of their lipoprotein and metabolic abnormalities. But treatment may involve statins.

This is entirely distinct from the "statins for all" argument, the simpleminded rule that primary care physicians and cardiologist are told to follow.

Groups who may indeed benefit from statin therapy include:

Homozygous or heterozygous familial hypercholesterolemia--Lacking a receptor for LDL particles, LDL piles up to very high levels in these people. LDLs of 300+ are common and lead to heart disease and stroke at relatively young ages.

Combined mixed hyperlipidemia--Among the one or more genetic defects underlying this condition involves excessive production of apoprotein B and VLDL particles. This leads to high risk for heart disease.

People unable to follow a diet to correct their lipid disorder--I have 80+-year old patients, for instance, who say, "I've eaten this way for 82 years. I'm not going to change now!" In the absence of diet and other efforts (e.g., omega-3 fatty acids from fish oil), drugs may be the answer.

In other words, of the $27 billion annual bill for statin drugs, perhaps a tiny fraction is truly necessary. The majority of people taking statin drugs would not really need them if they had the real answers. But don't let that confuse us: There are some people who do indeed benefit.

Butter and insulin

In a previous post, Atkins Diet: Common Errors, I commented on butter's unusual ability to provoke insulin responses. I offer this as a possible reason why, after a period of effective weight loss on a low-carbohydrate program, inclusion of some foods, such as butter, will trigger weight gain or stall weight loss efforts.

This develops because of butter's insulin-triggering effect, doubling or tripling insulin responses (postprandial area-under-the-curve). If insulin is triggered, fat gain follows.

Here's one such study documenting this effect: Distinctive postprandial modulation of ß cell function and insulin sensitivity by dietary fats: monounsaturated compared with saturated fatty acids

López et al 2008


From Lopez et al 2008. Mean (± SD) plasma glucose, insulin, triglyceride, and free fatty acid (FFA) concentrations during glucose and triglyceride tolerance test meal (GTTTM) with no fat (control), enriched in monounsaturated fatty acids (MUFAs) from refined olive oil (ROO meal), with added butter, with a mixture of vegetable and fish oils (VEFO) or with high-palmitic sunflower oil (HPSO). N = 14.

The postprandial (after-eating) area-under-the-curve is substantially greater when butter is included in the mixed composition meal. This effect is not unique to butter, but is shared by most other dairy products.

Fat, in general, does not make you fat. But butter makes you fat.

Vitamin D as a cardiovascular risk factor gains ground

If you were reading The Heart Scan Blog back in 2007, or read my Life Extension article on vitamin D deficiency as a cardiovascular risk factor, you already knew that vitamin D deficiency is rampant and adds to cardiovascular risk.

Results of a study from the Intermountain Medical Center Heart Institute in Utah bolster the concept that vitamin D deficiency is a cardiovascular risk factor, vitamin D normalization/supplementation reduces cardiovascular risk.

Science Daily reported:

For the first study, researchers followed two groups of patients for an average of one year each. In the first study group, over 9,400 patients, mostly female, reported low initial vitamin D levels, and had at least one follow up exam during that time period. Researchers found that 47 percent of the patients who increased their levels of vitamin D between the two visits showed a reduced risk for cardiovascular disease.


In the second study, researchers placed over 31,000 patients into three categories based on their levels of vitamin D. The patients in each category who increased their vitamin D levels to 43 nanograms per milliliter of blood or higher had lower rates of death, diabetes, cardiovascular disease, myocardial infarction, heart failure, high blood pressure, depression, and kidney failure. Currently, a level of 30 nanograms per milliliter is considered "normal."


Over the past 4 years, people in our program have been enjoying the extravagant benefits of vitamin D restoration. Cardiovascular benefits are becoming better documented and the bone health, cancer-preventing, insulin-normalizing, mood-adjusting, and anti-inflammatory effects likewise.

Atkins Diet: Common errors

No doubt: The diet approach advocated by the late Dr. Robert Atkins was a heck of a lot closer to an ideal diet than the knuckleheaded advice emitting from the USDA, American Heart Association, American Diabetes Association, and the Surgeon General's office.

But having just spent a week with Atkins low-carbers, here are some common errors that I see many make, errors that I believe have long-term health consequences, including impairment of weight loss.

Excessive consumption of animal products--Non-restriction of fat often leads to over-reliance on animal products. Higher intakes of red meats (heme proteins?) have been strongly associated with increased risk for colon and other gastrointestinal tract cancers. It is not a fat issue; it is an animal product issue. We should consume less meat, more vegetables and other plant-sourced foods.

Consumption of cured meats--Cured, processed meats, such as sausage, hot dogs, salami, bologna, and bacon, have a color fixative called sodium nitrite, an additive that has been confidently linked to gastrointestinal cancers. Risk is likely dose-dependent: The more you ingest, the greater the long-term risk.

Overconsumption of dairy products--Dairy products, especially milk, yogurt, cottage cheese, and butter, are potent insulinotropic foods, i.e., foods that trigger insulin release. There can be up to a tripling of insulin (area-under-the-curve) levels. This is not good in a world populated with tired, overworked pancreases, exhausted from a lifetime of high-carbohydrate eating.

Too many calories--While I agree that "a calorie is a calorie" and "calories in, calories out" are faulty concepts, I have anecdotally observed that long-time low-carbers often trend towards unlimited consumption of food, a phenomenon that seems to result in weight gain, especially in the sedentary. I wonder if this is a reflection of the insulinotropic action of dairy products and other proteins, compounded by the poor insulin responsiveness that develops with lack of physical activity. Factor into this conversation that lower calorie intake extends life, probably substantially (Sirt-2 activation and related phenomena, a la resveratrol). If lower calorie intake extends life, unlimited calorie intake likely shortens life.

Please don't hear this as low-carb bashing--it is not. It is a call to improve diets and not stumble into common traps that can impair heart health, weight loss, and longevity.

Fat Head: Tom Naughton's manifesto for low-carb eating

I just got back from Jimmy Moore's low-carb cruise to the Bahamas.

Among the many interesting people I met on the cruise was the creator of the documentary film, Fat Head, Tom Naughton.

Tom brings both creative insights into low-carbohydrate eating as well as humor. Low-carb eating can be a pretty contentious issue, but Tom made it fun. He will make you laugh about many of the odd notions we have about diet.

Among the best parts of Fat Head is Tom's portrayal of the effects of carbohydrates on insulin and fat metabolism:






Fat Head joins the ranks of films like Food, Inc, that make nutrition information entertaining. For anyone interested in a unvarnished look at diet, weight loss, along with a few laughs along the way, Tom Naughton's Fat Head is worth viewing.

Oatmeal: Good or bad?


You've heard it before: oatmeal reduces cholesterol. Oatmeal producers have obtained permission from the FDA to use a cholesterol-reducing claim. The American Heart Association provides a (paid) endorsement of Quaker Oats.

I've lost count of the times I've asked someone whether they ate a healthy breakfast and the answer was "Sure. I had oatmeal."

Is this true? Is oatmeal heart healthy because it reduces LDL cholesterol?

I don't think so. Try this: Have a serving of slow-cooked (e.g., steel-cut, Irish, etc.) oatmeal. Most people will consume oatmeal with skim or 1% milk and some dried or fresh fruit. Wait an hour, then check your blood sugar.

If you are not diabetic and have a fasting blood sugar in the "normal" range (<100 mg/dl), you will typically have a 1-hour blood glucose of 150-180 mg/dl--very high. If you have mildly increased fasting blood sugars between 100 and 126 mg/dl, postprandial (after-eating) blood sugars will easily exceed 180 mg/dl. If you have diabetes, hold onto your hat because, even if you take medications, blood sugar one hour after oatmeal will usually be between 200 and 300 mg/dl.

This is because oatmeal is converted rapidly to sugar, and a lot of it. Even if you were to repeat the experiment with no dried or fresh fruit, you will still witness high blood sugars in these ranges. Do like some people and pile on the raisins, dried cranberries, or brown sugar, and you will see blood sugars go even higher.

Blood sugars this high, experienced repetitively, will damage the delicate insulin-producing beta cells of your pancreas (glucose toxicity). It also glycates proteins of the eyes and vascular walls. The blood glucose effects of oatmeal really don't differ much from a large Snickers bar or bowl of jelly beans.

If you are like most people, you too will show high blood sugars after oatmeal. It's easy to find out . . . check your postprandial blood sugar.

In past, I recommended oat products, specifically oat bran, to reduce LDL, especially small LDL. I've changed my mind: I now no longer recommend any oat product due to its blood sugar-increasing effects.

Better choices: eggs, ground flaxseed as a hot cereal, cheese (the one dairy product that does not excessively trigger insulin), raw nuts, salads, leftovers from last evening's dinner.

Mustard: Super health food?

Could mustard--yes, the yellow condiment you smear on hot dogs--be a super heart healthy food in disguise?

Consider that mustard contains:

Vinegar

Turmeric

No appreciable sugar


The vinegar slows gastric emptying, resulting in slower absorption of any carbohydrates and a reduced glucose area-under-the-curve. Of the little fats contained (about 3 grams per 1/4 cup), most are desirable monounsaturates. Mustards are relatively rich in selenium, with 20 mcg per 1/4 cup, helpful for protection against cancer and thyroid disease, and magnesium, 31 mg per 1/4 cup.

Turmeric is added to most mustards. One of the constituents of turmeric, curcumin, the substance that confers the bright yellow color, has been a focus of interest for its anti-inflammatory effects. Curcumin has been documented to reduce activity of the inflammatory enzymes cyclooxygenase-2 (COX-2), lipoxygenase, and reduce activity of inflammatory signal molecules, tumor necrosis factor-alpha (TNF-a), interleukin (IL)-1,2,6,8, and 12, and monocyte chemoattractant protein (MCP). Curcumin also has been shown to reduce LDL oxidation, a potentially important step in atherosclerotic plaque formation. Turmeric is used as a tea by Okinawans. (Hmmmm . . . )

Turmeric content of mustard can vary, of course. Likewise, sugar content. Look for mustards that are not sweetened, so avoid honey mustard in particular. Look for hot, brown, horseradish, Dijon, etc. If there is a downside to mustard, it's sodium content, though the 709 mg per 1/4 cup should only be a problem for those who are sodium-sensitive (African Americans, in particular).

So perhaps mustard isn't exactly a super health food. But it may have some bona fide health effects and should be used generously especially if you are concerned about blood sugar and inflammatory phenomena.

Exercise and blood sugar

There is no doubt that exercise yields benefits across a spectrum of health: reduced blood pressure,  reduced inflammation, reduced blood coagulation, better weight control, stronger bones, less depression, reduced risk for heart attack.

Exercise also influences blood sugar. Diabetics understand this best: Exercise reduces blood sugar 20, 30, 50 or more milligrams. A starting blood sugar, for instance, of 160 mg/dl can be reduced to 80 mg/dl by jogging or riding a bicycle. (I recently had brunch at an Indian restaurant with my family. Blood sugar one-hour postprandial: 134 mg/dl. I was sleepy and foggy. I got on my stationary bike and pedalled at a moderate clip for 60 minutes. Blood sugar: 90 mg/dl.)

Could the reduction of blood sugar with exercise be THE reason that exercise and physical activity provide such substantial benefits?

Think about it. Reduced blood sugar:

1) Reduces risk for future cardiovascular events.
2) Reduces glycation of proteins, i.e., reduced glucose binding to proteins like the ones in artery walls and the lenses of your eyes.
3) Reduces blood coagulation
4) Reduces endothelial dysfunction (abnormal artery constriction that leads to atherosclerosis)

This might explain why it doesn't require high levels of aerobic activity to derive benefit from exercise, since even modest efforts (e.g., a 15-minute walk after eating) reduce blood sugar substantially.

The incredible 33-year, 18,000-participant Whitehall study tells us that a postprandial (after-eating) blood sugar of an impossibly-difficult 83 mg/dl is required to erase the excess cardiovascular risk of blood sugar. Could this simply be telling us that physical activity or exercise is required to suppress blood sugars to these low levels?

It makes me wonder if an index of the adequacy of exercise is your post-exercise blood glucose.

Is health the absence of disease?

It sounds like a word game, but is health the absence of disease?

In other words, if you're not sick, you must be well. If you don't have cancer, heart disease (overtly, that is, like angina and heart attack), the flu, diarrhea, fevers, pain someplace . . . well then, you must be well.

Of course, most of us would disagree. You can be quite unhealthy yet have no overt, explicit disease. Yet this is the philosophy followed in conventional medicine when it comes to many aspects of health.

With regards to heart disease, if you have no chest pain or breathlessness, you don't have heart disease. "Oh, all right, we'll perform a stress test to be sure." Track Your Plaque followers, as well as former President Bill Clinton, recognize the enormous pitfalls of this approach: It fails to identify the vast majority of hidden heart disease. In heart disease, the apparent lack of overt, sympatomatic "disease" does NOT equal the true absence of disease, even life-threatening.

How about nutritional supplements? Vitamin D is a perfect example. Blood levels of vitamin D of 10 ng/ml--profound deficiency--are common, yet people feel fine. Beneath the surface, blood sugar rises because of poor insulin response, hidden inflammatory responses are magnified, HDL is lower and triglycerides are higher, coronary plaque grows at an accelerated rate, colon cancer activity is heightened . . . Though you feel fine.

Can an abnormal "endothelial response" be present while you feel fine? You bet it can. This refers to the abnormal constrictive behavior of arteries that is present in many people who have hidden coronary plaque or risk for coronary plaque, but is entirely beneath consciousness.

How about a triglyceride level of 200 mg/dl, fatally high from the Track Your Plaque experience? (We aim for <60 mg/dl.) This is typical in people who follow the diets endorsed by agencies like the American Heart Association and the American Diabetes Association, organizations too eager to keep the money flowing from corporate sponsors and thereby offer us their advice based more on politics and less on health. Triglyceride levels of 200 mg/dl cause no symptoms.


At so many levels, the absence of disease is NOT the same as health. Health is something that is expressed by, yes, feeling good, but it's also measured by so many other factors hidden beneath the surface. An annual physical is one lame effort to address this aspect of "health." But it needs to go farther, much farther.

Heart scan, lipoprotein testing, vitamin D blood level--those are the basic requirements to go beyond the shortsighted practice of the conventional approach in the world of heart disease.

Cuckoo for Cocoa Puffs





Take a look at the list of ingredients in Cocoa Puffs: corn, sugar, corn syrup--all high glycemic index foods.

In other words, Cocoa Puffs is the physiologic equivalent of pure table sugar. Sure, it comes packaged with this wacky bird and the back of the box usually has fun games and offers. There's also the clever, fast-paced TV commercials to remind you of how fun Cocoa Puffs can be.


What is the actual consequence of a breakfast of a food like Cocoa Puffs in a cup of skim milk? That's easy: A big surge in insulin and blood sugar (from the corn and sugar), a drop in HDL cholesterol, surge in triglycerides (from the sugar and sugar-equivalents), increase in small LDL. Beyond this, you raise blood pressure and experience an insatiable increase in appetite. Then you get fat.

Obviously, none of this is desirable. Then why does the American Heart Association allow its Heart CheckMark endorsement on the package?

The Heart Association is trapped in 1982. Low-fat was in, saturated fat was the sole enemy of heart disease.

In 1982, the evils of small LDL, for instance, were unappreciated. LDL cholesterol was LDL cholesterol--all of it was bad and saturated fats seem to raise LDL. But the story has evolved enormously since then: LDL is not all the same. Small LDL is among the principal culprits in heart disease, the same small LDL hugely magnified by Cocoa Puffs and other similar products that fill 70% of supermarket shelves.

The American Heart Association needs to get with the times. The conversation on healthy diets has progressed considerably. Yet garbage foods that wreak havoc on health like Cocoa Puffs continue to be endorsed by an organization that still carries substantial clout with the American consumer.

My advice: Until they change their tune, anything that carries the endorsement of the American Heart Association should be eliminated from your diet.

Further validation of the Track Your Plaque 60:60:60 targets

The latest analysis of the data from Treat to New Targets (TNT) Trial shows that higher HDL cholesterol values are associated with reduced risk of heart attack, even in those with low LDL cholesterol values.

This counters the argument that some have made that, if a person takes a statin drug, raising HDL adds no additional benefit.

In the 9770-participant trial (randomized, double-blind), participants were given atorvastatin (Lipitor®) 10 mg or 80 mg per day. The study was sponsored by Pfizer, the manufacturer of Lipitor®. All participants were survivors of heart attacks, significant coronary disease by heart catheterization, or had previously undergone coronary angioplasty, stent placement, or bypass surgery—a high-risk group.

At the third month of enrollment, lipid (cholesterol panel) values were obtained and used as the basis for analysis. Participants on 80 mg atorvastatin achieved an average LDL cholesterol (Friedewald) of 77 mg/dl; participants taking 10 mg achieved a level of 101 mg/dl. Using these values, 8.7% of participants taking the higher dose of drug experienced an event, compared to 10.9% on the lower dose (which the investigators called a 22% relative reduction).

However, when the groups were re-analyzed by HDL cholesterol levels, higher HDLs remained predictive of less heart attack and other events, with the group having the highest HDL of =55 mg/dl experiencing 25% less events. Most interestingly, this effect was upheld even in participants with very low LDL cholesterols of <70 mg/dl.

I'm always a bit leery of drug company-sponsored studies, especially ones in which virtually all the participants tolerated a drug like Lipitor 80 mg, a dose in my experience that is very poorly tolerated for more than a few months. (Muscle aches are, in my experience, inevitable. I do not even recommend this dose.) In other words, the data are, in that respect, too good to believe.

Anyway, despite my reservations about these big money studies, there was nothing to gain from the HDL observation. (Of course, at one time, there would have been, given Pfizer's efforts to commercialize the now-kaput torcetrapib, scrapped because of excess mortality in phase II trials.)

Thankfully, there's other data that likewise suggest that the higher the HDL, the better. Yet more validation for the Track Your Plaque lipid targets of LDL 60 mg/dl, triglycerides 60 mg/dl or less, HDL 60 mg/dl or greater.

My sister called today . . .

My younger sister, aged 48 years (sorry, sis), called this morning.

"I'm going to my doctor today. What labs should I tell him to draw?" she asked.

"Why do you have to tell him? Can't you just ask him what he thinks should be drawn?"

"No," she said. "He just draws what I tell him to."


Maybe my sister is bossier than most. But I've heard this from many patients, as well. They go to their primary care physician and end up requesting this or that test. Sometimes their doctor complies. Often, they resist and refuse to do so.

I've heard many complaints from patients about doctors refusing to order even fairly benign tests like a vitamin D blood level or lipoproteins, even a C-reactive protein.

The number of these sorts of complaints seems to be growing. Ten years ago, it rarely happened. Today, I hear this nearly every day.

I think it is symptomatic of the growing discontent we all have with the status quo in healthcare. We are all expected to submit to the paternalistic, what-can-you-possibly-know mentality that still rules the day in medical offices. Only 40-50 years ago, if you wanted to look at a medical book, you'd have to ask the librarian for special permission so that they could make sure you weren't just a pervert trying to look at naked bodies. Today, every manner of medical and health information can be found online. Quite a contrast.

We are entering a new age, one in which people are far better informed, have surfed the internet and read media reports on health topics, have been exposed to drug company advertising, and know a fair amount about nutritional supplements. I think the system needs to change to accommodate this rapidly growing hyper-knowledgeable society.

In past, when a health problem turned up, you'd turn to your doctor first. I predict that,in the next few years, we will use the doctor as a place of last resort, the person we turn to when all else has failed, after you've exhausted your information sources.

I hope that the Track Your Plaque process will become one of the engines of change, an information resource that provides empowering tools that don't replace your doctor, but provide many information tools that are superior and may minimize your reliance on a health care provider.

Failure to diagnose

I picked up a hospital publication today. Featured prominently on the cover was a glossy photo of an attorney and his wife, both smiling.

The headline: "Atorney grateful for the lifesaving work of the ______ Hospital."

The story detailed the near-tragic story of how this 59-year old man was exercising at his local gym, only to lose consciousness after stepping off one of the exercise machines. Bystanders--hospital employees, as luck would have it--checked the man's pulse: none. They performed CPR. Ambulance called, blah blah blah.

Severe coronary disease discovered, extensive atherosclerotic plaque in all three coronary arteries, a 12-inch chest incision later and he and his wife are eternally grateful for the fine work done at X hospital. And so they should be for a job well done.

But wait a minute. After the urgent hospital dust settled, did anyone ask the one crucial question: Why wasn't this man's far-advanced heart disease identified? Why did he have to die and be resuscitated before his disease was recognized?

If this man was an indigent, homeless alcoholic . . . well, perhaps it would be no surprise. Health is neglected in this population. But a successful attorney?

Detecting hidden coronary atherosclerotic plaque simply isn't that tough. In Milwaukee, $199 would have diagnosed his disease unequivocally.

Unfortunately, we still have to set off drumrolls and crash cymbals to even begin to get the attention of the practicing physicians around us who continue to fail to diagnose hidden coronary disease. I wouldn't be at all surprised to hear if this man had a $4000 nuclear stress recently that was normal. Why would a nuclear stress test be normal? Easy: Wrong test.

The hidden message: The failure to diagnose paid somebody and some hospital over $100,000. So, why bother detecting disease before the payoff?

The profit motive in all this is all too obvious. The only other explanation is the enormous, repetitive, and systematic stupidity of the conventional approach to heart disease detection. You have the solution, at least for you and the people around you, in a CT heart scan and in the Track Your Plaque program.

Interview with world heart scan authority, Dr. John Rumberger












Dr. John Rumberger has, from its start, been a good friend of the Track Your Plaque program.

We are very proud to have his friendship. Dr. Rumberger is not only a world-renowned scientist in the world of cardiac imaging and heart scanning, but also a humanitarian and gentleman. From the very first day I met Dr. Rumberger many years ago, when he answered my many silly and naive questions about heart scans, I came to appreciate his deep and genuine interest in improving the world of heart disease detection.

I tracked Dr. Rumberger down from his busy schedule, now on a new project at the Princeton Longevity Center in Princeton, New Jersey.




TYP: Dr. Rumberger, we understand that your career has taken a new direction. Can you tell us about your current project?

Dr. Rumberger: I have not really taken a new direction, but further expanded on my opportunities.

I remain Medical Director of PrevaHealth Wellness Diagnostic Center (formerly Healthwise) in Columbus, Ohio. At that center, we see patients referred by their doctors for further refinement in cardiac risk stratification using heart and body scanning. However, by only doing scans alone there are limited opportunities for me to react in a meaningful way with the individual patients and thus I miss opportunities to do direct one-on-one teaching.

Currently, I spend most of my time in Princeton, NJ as Director of Cardiac Imaging for the Princeton Longevity Center. At the PLC, we perform comprehensive medical examinations along with screening CT scans, blood work, fitness and diet consultation to affect a more thorough one-on-one experience. Each patient then receives a comprehensive de-briefing.

In addition, since I have been involved with cardiac CT for now nearly 24 years, the PLC also affords me an opportunity to develop a CT coronary angiography training program for cardiologists and radiologists (www.cardiaccta.us). Together, these new efforts are merely an extension of my interests in prevention, patient care, and teaching.



TYP: Based on your book, The Way Diet, we understand that you advocate gravitating away from processed foods and incorporating more nuts, monounsaturated oils, lean proteins like fish, and a reduction in processed carbohydrates. You’ve also been a proponent of the Mediterranean diet that demonstrated a dramatic reduction in cardiovascular events in the Lyon Heart Study.

Has your philosophy or practice regarding nutritional strategies evolved or changed in any way since your book was published?

Dr. Rumberger: No, the strategies put forward in The Way Diet have, if anything, been reinforced by further and further research in selecting foods that are naturally high in anti-oxidants with lean sources of protein and reduced intake of processed sugar-containing preparations. The book, however, is what I call a ‘philosophy’ book which looks at three major aspects: proper diet, adequate exercise, and stress management. I also include some recipes which follow the dietary plans, but are done using ingredients that are commonly found in the average home.



TYP: We regard you as the source of much of the wisdom in heart scanning as the basis for early heart disease detection. Much of the original and subsequent scientific data, in fact, bears your name. Can you touch on some of the new directions your research has taken over the past couple of years?

Dr. Rumberger: We have come a long way from the beginning and there is a long way to go to get this incorporated into routine preventive care in the United States.

The most recent research has provided not so much more information as continuing to reinforce the old research. As I always say: if your research continues to show the same thing, then maybe there is a clear pattern here! The biggest challenge is getting this message into the mainstream and also trying to get cardiologists (and internists and, in fact, the general public) away from ‘stenosis’ detection to define the real cause of heart attacks (plaque) and into ‘plaque detection.’ This is where basic heart scanning has the greatest potential to reduce the expanding burden of heart disease.

You may be aware of our SHAPE initiave in which an international group of cardiologists and scientists have advocated getting a heart scan FIRST and then, if abnormal, checking your cholesterol values; rather than using cholesterol (which is valuable, but highly variable in predictive power) to determine who needs medications or further testing. The heart scan can define the current level of plaque and THEN you can determine what to do about it. [See the Track Your Plaque report on the release of the Shape Guidelines at SHAPE Guidelines]



TYP: We understand that you are performing CT coronary angiography in your center. What are your thoughts on the role of CTA in 1) screening for coronary disease, and 2) its role in the diagnostic process?

Dr. Rumberger: CT coronary angiography (CTA) is an incredible method to really define the extent of disease, beyond just coronary calcium. Its role is most appropriate in ruling OUT a significant ‘stenosis’ while really defining the absence or presence (and thus ‘how much’) of plaque. It is the ultimate ‘plaque detector’. CTA is best used in patients who have some symptoms, but in whom the clinician feels may NOT have clear cardiac chest pain. By risk-stratifying using CTA, we also gain information about heart size, heart function, whether there is prior heart damage, as well as other important information. This then becomes a very universal means to risk-stratifying individuals.



TYP: Thanks for your wonderful insights, Dr. Rumberger! We look forward to hearing about your future projects and research directions.

Summer in Wisconsin

It's been a glorious summer in Wisconsin.

For weeks straight, we've enjoyed bright, sunny days with temperatures in the 70s and 80s. Even now, in late September, our windows are wide open and the days are warm and sunny. Yesterday, it was 84 degrees. Yes, it did rain for a stretch of about 10 days in August, but for the most part it has been a wonderfully sunny summer.

So it struck Andy as a big surprise when we checked his 25-OH-vitamin D3 blood level: 15 ng/ml--severe deficiency.

"I don't get it. I'm outside almost every day. Look at me! How do you think I got this tan?"

Indeed, Andy sported a nice dark tan over exposed areas.

In fact, Andy was among the dozen or so people this month with deficiencies of this magnitude.

Deficiency is not the exception; it is the rule. Of course, if Andy's blood level is at the level of severe deficiency in September, he will only trend lower over the next few weeks and months. He would likely have shown vitamin D blood levels of <10 ng/ml by January--profound deficiency.

With deficiency of this severity, Andy has been exposing himself to risk for prostate and colon cancer, diabetes and metabolic syndrome, low HDL, higher triglycerides, higher blood sugars, higher C-reactive protein, osteoporosis, arthritis . . .

Correcting the deficiency is easy. But, as you can see, getting sun is not always the answer. Even with an active, outdoor lifestyle and a tan, Andy still remained significantly deficient. Oral replacement with vitamin D3, or cholecalciferol, is an absolute necessity.

Wacky statin effects

In general, I try to exhaust possibilities before resorting to the statin drugs. But we still do use them, both in general practice and the Track Your Plaque program.

There are indeed a number of ways to reduce, minimize, or eliminate the need for these drugs. For instance, if your LDL is 150 mg/dl but comprised of 90% small particles, then a reduction in wheat and other high-glycemic index foods, weight loss, fish oil, and niacin can yield big drops in LDL.

But sometimes we need them. Say LDL is 225 mg/dl and is a mix of large and small. Exercise, weight loss, niacin, oat bran, ground flaxseed, Benecol, etc. and LDL: 198 mg/dl. Alright, that's when statins may be unavoidable. There's also many people who are not as motivated as all of us trying to reverse heart disease. Some just want the easy way out. Statins do indeed provide that option in some people.

So in truth, we end up using these drugs fairly regularly. How common are muscle aches and fatigue? In my experience, they are universal . If taken long enough, or if high doses are used, muscle complaints are inevitable. Most of the time, thankfully, they're modest and often relieved with a change in drug or with coenzyme Q10 supplementation.












But there's more to statin side effects than muscle aches. Among the wacky effects that I have witnessed with statin drugs:

--Insomnia-especially with simvastatin (Zocor and Vytorin). Insomnia can be quite severe, in fact, with difficulty sleeping more than 3-4 hours a night.

--Bone aches--I don't know why this happens, unless it's somehow related to muscle aches. I've seen this with all the statins, but more commonly with Crestor.

--Memory impairment--a la Dr. Duane Graveline's wacky book, Lipitor: Thief of Memory. I've seen this with Lipitor, though it's uncommon, and less commonly with simvastatin (Zocor, Vytorin).

--Diarrhea--More common with Zetia and Vytorin (which contains Zetia), because of the inhibition of bile acid reabsorption.

--Migraine headaches--This I certainly do not understand, but the cause-effect relationship is undoubtedly true in an occasional person.

--Low libido--In men more than women, though it may be more due to men being more willing to admit to it.

--Increased appetite--Rare, though I've seen dramatic instances.

--Tinnitus--Ringing in the ears. I've only seen it with Lipitor and Zocor.


In their defense (and in general I am no defender of the drug manufacturers), most people do fine with statin drugs, though the majority do eventually require coenzyme Q10 in my experience. By the way, coenzyme Q10 can be an indispensable aid to help tolerate statin agents.

I'd love to hear about your wacky experiences.

Track Your Plaque goes global

I don't use this space to toot my horn (at least I don't too often), but we were looking at the listings of our viewers and members. I was surprised to learn that we now have Track Your Plaque followers in 15 different countries around the world!

We have members from Europe including England, Ireland, Switzerland, Belgium, and the Czech Republic. We have members from as far away as South Africa, Australia, India, Singapore, Thailand, and China.

I see the entire Track Your Plaque process as a grand experiment. Never before in history has a system of health been delivered via a communication medium like the web. The internet provides more interactivity than television, it's more fluid than a book, it's more dynamic and evolves more rapidly than a face-to-face interaction. While we cannot be hands-on over the internet, we can still deliver all the crucial information and, hopefully, the knowledge on how to get it done.



Track Your Plaque is part of an even grander experiment: The movement to shift control over health away from the medical system, doctors, and hospitals and back to individuals. When you think about it, the idea that "health" (more acurately sickness) should be managed by people and institutions (e.g., hospitals and insurance companies) outside of the individual is a 20th century concept. I predict that this notion will also become a relic of the 20th century.

Someday, we will look back and laugh at the folly of the 20th century style of paternalistic health care. Perhaps it was a necessary step in the sequence to transform health to a better system that returns control to the individual. But it's clearly time for a change.

Track Your Plaque is an example of the extraordinary power that can be taken by a lone individual with only minimal assistance of a health care provider. I see Track Your Plaque members who understand heart disease (at least the coronary disease aspect) far better than 95% of my cardiology colleagues, 100% of my internal medicine and family practice colleagues. Physicians maintain a role, but their role has shrunk and receded. They should be facilitators of success in health, educators, a resource to turn to when we need help. It's not that way today. It will be in 50 years.

But, right now, we can get started on this wonderfully self-empowering--liberating-- movement by participating in this global experiment known as Track Your Plaque, the program with the goofy name that has the potential to usurp and unravel this enormous institutionalized system of health care the world has created.

Go to your corners

There's a heated debate being waged on the Heart Hawk Blog

Dr. Melissa Walton-Shirley authored an editorial entitled It Should Be the Right of All Americans to Have Primary Percutaneous-Based Intervention for Acute Coronary Syndrome .

Heart Hawk's response:

Dr. Walton-Shirley feels the best use of time, talent, and money is to build more cath labs and train more people in how to use them so that IF you have a heart attack, you stand a better chance of being pulled back from the brink of death. Unfortunately, you have to first let people get so sick that they are about to die. My position is to use those same resources to prevent such disasters from happening in the first place. Take your pick. You cannot spend the money twice.

I am no stranger to "direct angioplasty," meaning performing immediate coronary angioplasty (with stenting) for heart attack. Since 1990, I have personally performed hundreds, perhaps over a thousand of these procedures, particularly when I was younger and my practice was procedurally-focused. But, after a few years, I quickly recognized the futility of this approach. Yes, you might have aborted a heart attack ,perhaps even saved a life at the brink of death. But wouldn't it have been better to have prevented the entire episode in the first place?

In my mind, putting a cath lab on every corner, as Dr. Walton-Shirley suggests, is like having a fire truck on every street to prevent a house from burning down. It's an enormously expensive proposition that provides no incentive to prevent fires. Why not spend the money on preventing the fires?

Expanding access to cath lab procedures is putting the fox in the henhouse. Procedures yield money--big money--for hospitals and cardiologists. Guess what happens when you build facilities that exceed the need? Yes--the number of procedures grows, whether or not they were needed.

In my view, Dr. Shirley-Walton's opinions are symptomatic of the profit-driven, procedurally-focused quick-fixes that divert money that would be far better spent on effective dissemination of preventive practices.

Calcium reflects total plaque





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

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

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

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

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

Don't mistake marketing for truth

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

For instance:

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

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

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

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

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


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

Tattered Red Dress

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


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

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



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

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

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

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

Panic in the streets

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

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

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

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

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

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

Heart scan curiosities 1

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

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



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

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

Annual physical

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

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

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

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

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

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

A curious case of regression

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

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

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

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

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

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

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

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

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

Fortune teller

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

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

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

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


Let's take three typical examples:

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

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

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

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

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

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

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

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

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

Heart scan score drops like a stone

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

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

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

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

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

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

How's that for an early Christmas gift?

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

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

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

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

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

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

For additional comments on progesterone, read the Track Your Plaque interview with women's hormone expert, Dr. Nisha Jackson, Females, hormones, and weight control:
