Risks for coronary disease 2008

According to conventional thinking, there are identifiable risks for coronary disease and heart attack. These risk factors are:

* smoking
* high blood pressure
* high blood cholesterol and excessive saturated fat intake
* diabetes
* being overweight or obese
* physical inactivity

I'd agree with all the factors listed (though I would argue about the importance of high blood cholesterol and saturated fat; they are not as important as commonly made to be.)

Is the list complete?

From the unique perspectives gained in the Track Your Plaque program, I'd offer a significantly different list. Trying to stop or reduce coronary atherosclerotic plaque and heart scan scores makes you a whole lot smarter about what works and what doesn't work.

So, in addition to the risk factors listed above, I would add:

* Small LDL particles--Lots of small LDL particles is MORE important than high LDL.
* High blood pressure with exercise
* Excessive wheat intake and other processed carbohydrates--An issue of explosive importance today. Wheat creates large numbers of small LDL particles, among other adverse effects.
* Vitamin D deficiency--Among the most powerful risks I know of. It belongs at the top of the list.
* Vitamin K2 deficiency
* Low HDL cholesterol
* Blood sugar >100 mg/dl
* High triglycerides--While some argue about whether triglycerides are a risk that behaves independently of patterns like low HDL, they are neglecting the potent force of this risk. Sure, it occurs in tandem with low HDL (usually, though not always), but it is a factor that can leave you with risk even when HDL is raised to healthy levels.
* Lipoprotein(a)--It is eminently, positively crystal clear that lipoprotein(a) is a powerful risk for heart disease. The lack of a profitable treatment keeps it hidden in the shadows.
* Pessimism--Be happy, do better. Be a constantly angry, frustrated, complaining sourpuss and you are more likely to succumb to heart disease, cancer, or other undesirable fate.


These are the risk factors that we address through the Track Your Plaque program, a list that yields a far more powerful and comprehensive approach to control over coronary plaque/atherosclerosis, sufficient to achieve reversal in many (though not in all) instances.

I view the list of conventional risk factors as a "no brainer" list. Sure, smoking is a risk factor. But there are virtually no smokers in the Track Your Plaque program. If you smoke, you clearly don't care enough to engage in a high-intensity prevention program like this.

Saturated fat? Perhaps, but the battlefield of heart disease is riddled with the bodies of those who employed this as their sole strategy and failed catastrophically.

Diabetes, hypertension, and overweight all represent a continuum of risk; the solutions offered in the conventional scheme (i.e., low-fat diet, etc.) make these patterns worse, not better.

The conventional response to heart disease risk is trapped somewhere in 1973 and has not changed in over 30 years. Heart disease continues to be a growth industry for hospitals and the pharmaceutical and medical device industries. The "official" organizations continue to deliver an antiquated, outdated message.

If you want heart disease, follow the American Heart Association diet. If you want established heart disease to get worse, follow the American Heart Association diet. If you want diabetes or, if you already have diabetes or pre-diabetes, if you want it to worsen and develop organ damage (eyes, kidneys, nervous system, etc.), then follow the American Diabetes Association diet. USDA food pyramid? Loosen your belt!

The list of conventional risk factors for heart disease is woefully inadequate. If that is as far as your prevention program takes you, heart disease will not be controlled or prevented. At best, it might be slowed; at worst--and more likely--it might be accelerated.

Food sources of vitamin K2



Vitamin K2 is emerging as an exciting player in the control and possible regression of coronary atherosclerotic plaque. Only about 10% of dietary vitamin K intake is in the K2 form, the other 90% being the more common K1.

The ideal source of K2 is natto, the unpalatable, gooey, slimy mass of fermented soybeans that Japanese eat and has been held responsible for substantial decreases in osteoporosis and bone fractures of aging. Natto has an ammonia-like bouquet, in addition to its phlegmy consistency that makes it virtually inedible to anyone but native Japanese.

I say that the conversation on vitamin K2 is emerging because of a number of uncertainties: What form of vitamin K2 is best (so-called MK-4 vs. MK7 vs. MK-9, all of which vary in structure and duration of action in human blood)? What dose is required for bone benefits vs. other benefits outside of bone health? Why would humans have developed a need for a nutrient that is created through fermentation with only small quantities in meats and other non-fermented foods?

Much of the developing research on vit K2 is coming from the laboratories of Drs. Vermeer, Geleijnse, and Schurgers at the University of Maastricht in the Netherlands, along with several laboratories in Japan, the champions of K2.

MK-7 and MK-8,9,10 come from bacterial fermentation, whether in natto, cheese, or in your intestinal tract; MK-4 is naturally synthesized by animals from vitamin K1. While natto is the richest source of the MK-7 form, egg yolks and fermented cheeses are the richest sources of the MK-4 form.

Chicken contains about 8 mcg MK-4 per 3 1/2 oz serving; beef contains about 1 mcg. Egg yolks contain 31 mcg MK-4 per 3 1/2 oz serving (app. 6 raw yolks). Hard cheeses contain about 5 mcg MK-4 per 3 1/2 oz serving, about 70 mcg of MK-8,9; soft cheeses contain about 30% less. Natto contains about 1000 mcg of MK-7, 84 mcg MK-8, and no MK-4 per 3 1/2 oz serving.











Feta cheese

Thanks to the research efforts of the Dutch and Japanese groups, several phenomena surrounding vitamin K2 are clear, even well-established fact:

--Vitamin K2 supplementation (via frequent natto consumption or pharmaceutical doses of K2) substantially improves bone health. While K2 by itself exerts significant bone density/strength increasing properties in dozens of studies, when combined with other bone health-promoting agents (e.g., vitamin D3, prescription drugs like Fosamax and calcitonin), an exaggerated synergy of bone health-promoting effects develop.



--The MK-4 form of vitamin K2 is short-lived, lasting only 3-4 hours in the body. The MK-7 form, in contrast, the form in natto, lasts several days. MK-7 and MK-8-10 are extremely well absorbed, virtually complete.

--Bone health benefits have been shown for both the MK-7 and MK-4 forms.

--Coumadin (warfarin) blocks all forms of vitamin K.





Interestingly, farm-raised meats and eggs do not differ from factory farm-raised foods in K2 content. (But please do not regard this as an endorsement of factory farm foods.)

Another interesting fact: Since mammals synthesize a small quantity of Vit K2 forms from vitamin K1, then eating lots of green vegetables should provide substrate for some quantity of K2 conversion. However, work by Schurgers et al have shown that K1 absorption is poor, no more than 10%, but increases significantly when vegetables are eaten in the presence of oils. (Thus arguing that oils are meant to be part of the human diet. Does your olive oil or oil-based salad dressing represent fulfillment of some subconscious biologic imperative?)

If we believe the data of the Rotterdam Heart Study, then a threshold of 32.7 micrograms of K2 from cheese yields the reduction in cardiovascular events and aortic calcification.

It's all very, very interesting. My prediction is that abnormal (pathologic) calcium deposition will prove to be a basic process that parallels atherosclerotic plaque growth, and that manipulation of phenomena that impact on calcium depostion also impact on atherosclerotic plaque growth. Vitamins D3 and K2 provide potential potent means of at least partially normalizing these processes.

As the data matures, I am going to enjoy my gouda, Emmenthaler, Gruyere, and feta cheeses, along with a few egg yolks. I'm going to be certain to include healthy oils like olive and canola with my vegetables.

Track Your Plaque: Naughty or nice?



Among the many wonderful surprises we've had at Track Your Plaque this holiday season was a letter from Santa Claus himself!

It seems that Santa, like the rest of us, has been busy surfing the web for useful health information the last few months. He was struck with this curious discussion we've been having about "wheat belly" and all the unhealthy consequences of wheat products in our diet.

He writes:

"I wouldn't have believed it myself, except that my waist size has grown four inches in as many years. Sure, I'm known for my healthy girth, but now even Mrs. Claus calls me fat!

"I was open to new ideas when I came across this crazy discussion about eliminating wheat from your diet. So I said, "What have I got to lose?" Well, four weeks later and 12 lbs lighter, I'm convinced. Now comes the tough part: I've got to deliver all the toys and resist all those cookies the children put out for me. I wonder if wheat makes reindeer fat, too?

"Anyway, thanks to your program I'm back to my old weight again. Doc says my blood sugar and blood pressure are also back down to normal. Thanks, Track Your Plaque! (You'll find something extra special under the tree this year.)"

And so it goes. I'm tempted to put Santa's testimonial on our homepage, but I think that may be tooting our own horn a bit too much.

Have a wonderful holiday!

Vitamin D: Treatment for metabolic syndrome?

Metabolic syndrome is that increasingly common collection of low HDL cholesterol, high triglycerides, high blood sugar, and high pressure that now afflicts nearly 1 in 4 adults, rapidly gaining ground to 1 in 3. Beyond these surface factors, metabolic syndrome also creates small LDL particles, VLDL, intermediate-density lipoproteins (IDL), increased imperceptible inflammation measured as higher c-reactive protein, and greater blood clotting tendencies. Metabolic syndrome is usually, though not always, associated with a big tummy ("beer belly," though I call it "wheat belly").

In short, metabolic syndrome creates a metabolic mess that leads to dramatic increases in heart disease, vascular disease and stroke, and cancer. The medical community has been paying increasingly greater attention to this condition because of its booming prevalence and because of the big bucks invested in "education" by the manufacturers of the diabetes and pre-diabetes drugs, particularly makers of Actos and Avandia.

But here's a curious observation:

Replacement of vitamin D to healthy levels (we aim for 50-60 ng/ml, or 125-150 nmol/l) yields:

--Higher HDL
--Lower triglycerides
--Lower blood sugar
--Reduced c-reactive protein
--Reduced blood pressure
--Reduced small LDL
--Enhanced sensitivity to insulin

(Whether blood clotting and effects on IDL should be added to this list is uncertain.)

It's obvious: Vitamin D is proving to be a very important and powerful corrective influence on many of the facets of the metabolic syndrome. In fact, I would go as far as saying that, side by side, vitamin D yields nearly the same effect as prescription drugs Actos and Avandia--without the extravagant cost (nearly $200 per month), leg swelling, congestive heart failure and heightened heart attack risk (with Avandia), and average 8 lb weight gain. Of course, vitamin D also provides benefits beyond metabolic syndrome like facilitation of coronary plaque regression, increased bone density, reduced arthritis, and reduced risk of several cancers.

You'd think that agencies like the American Diabetes Association (ADA) would be all over vitamin D like white on rice. Yet they remain curiously quiet about the entire issue. (That should come as no surprise to anyone familiar with the behavior and politics of this organization, the same outfit that has widely propagated the ADA diet, a program that accelerates diabetes and its complications. In my view, the ADA is an embarassment.)



For a really great story and video on vitamin D that includes a terrific interview with vitamin D guru and Track Your Plaque friend, California psychiatrist Dr. John Cannell, go to What's the Real Story on Vitamin D?. While the video will yield little new to readers of The Heart Scan Blog or Track Your Plaque members, it just feels really good to see a well-made, high-class video production echoing many of the things we've been talking about these past two years.

Appetite stimulants

Ever have days when you just can't seem to get enough to eat, your stomach gnawing just a hour after a meal? We all get them, some more than others. Other days, you can be content with a few simple foods and hunger is subdued, temptation easy to control.

Why such contrasts on different days?

A major part of the reason can be the presence of appetite stimulants, factors that trigger appetite beyond rational control. The list of common appetite stimulants includes:

--Sleep deprivation--A very important factor. Lack of sleep drives tremendous appetite, and often for the wrong foods (processed carbohydrates). I personally have experienced my most shamefully indulgent days when sleep-deprived. The solution is obvious: Sleep. Another factor that is based purely on personal observation is that of waking mid-phase. In other words, waking up while you're still enjoying the deeper phases of sleep (e.g., phase 3,4, or REM). This can oddly disrupt your day and your impulse control. I usually try and time sleep to increments of 90 minutes to coincide with the average duration of the full cycle of sleep. For example, 7 1/2 hours is better than 8 hours, since the extra half hour puts your square into a deeper sleep cycle.

--Excessive caffeine--Caffeine stimulates stomach acid. This triggers the impulse to eat . . . and eat and eat.













Image courtesy Wikipedia

--Aspirin and other anti-inflammatory agents--If you take aspirin (as many of our Track Your Plaquers do), then beware of the gastritis that can develop. Like excessive caffeine, it also triggers the impulse to eat, likely a protective mechanism, since food sops up excess acid. I ask patients to take periodic breaks from aspirin, e.g., a week off every two or three months, to allow the stomach to heal. Alternatively, an occasional dose of acid-suppressing medication is a safe practice, e.g., Pepcid AC 10-20 mg; Prilosec 10-20 mg.

--Wheat-containing foods--Followers of The Heart Scan Blog know my feelings on this. Wheat is a potent appetite stimulant: Eat something containing wheat like a pretzel or whole wheat bagel, and you want more. You may want more immediately, or a little later when your blood sugar plunges after the wheat-driven insulin surge. Solution: Dump the wheat, one of the most unhealthy food groups around.

--Alcohol--Though perhaps not a direct appetite-stimulating effect, the loss of impulse-control with alcoholic drinks can lead to overindulgence, often in the worst foods. Just beware.

--Hanging around with heavy people. Remember peer pressure? It can be subliminal. People with poor eating habits provide the silent message that it's okay to yield to impulse, overeat, overindulge, and choose the wrong foods.

--Stress--Whether through cortisol stimulation or other means, stress triggers appetite in some people. If you experience this and must give in, reach for raw nuts or nuts, rather than wheat snacks or chips. The effect will be minimal, perhaps even beneficial, rather than the bloating, appetite-stimulating, fattening effect of crackers, chips, or pretzels. This may be the same phenomenon as taking prescription steroids like prednisone.

--Short dark days, long nights--In other words, winter. Though just an anecdotal observation, I am convinced that vitamin D supplementation is an effective antidote to this effect. The short, dark days just don't bother you as much, perhaps not at all, and there's no impulse for comfort foods.


How about appetite suppressants? In this list I would include 1) raw nuts--especially almonds, walnuts, pecans, and pistachios, the sort with a fibrous covering and rich in monounsaturates, 2) other sources of plentiful healthy oils, e.g, use more olive oil in your salad or add it to hummus for your veggie dip, 3) space-occupying fibers such as glucomannan, inulin (such as in Fiber Choice), and psyllium seed products. Counteracting the above appetite stimulants like sleep deprivation is, of course, important.

The coming wheat frenzy, otherwise known as the holidays, is an especially important time to be aware of these effects. Eat, drink, and be merry--but with rational impulse control not driven by subconscious appetite stimulants.

"Heart scans are experimental"

Let me warn you: This is a rant.

It is prompted by a 44-year old woman. She has a very serious lipoprotein disorder. Her family experiences heart attacks in their 40s and 50s. I asked for a heart scan. Her insurance companied denied it.

This is nothing new: heart scans, like mammograms, have not enjoyed reimbursement from most insurers despite the wealth of data and growing acceptance of this "mammogram" of the heart.

However, 10 minutes on the phone, and the "physician" (what well-meaning physician can do this kind of work for an insurance company is beyond me) advised me that, while CT heart scans for coronary calcium scoring are not covered, CT coronary angiograms are.

Now, I've been witnessing this trend ever since the big players in CT got involved in the game, namely Philips, Siemens, Toshiba, and GE. These are enormous companies with hundreds of billions of dollars in combined annual revenues. They, along with the lobbying power of cardiology organizations like the American College of Cardiology, have gotten behind CT coronary angiograms. This is most likely the explanation of why CT coronary angiograms have rather handily obtaining insurance reimbursement. Interestingly, the insurance company I was speaking to is known (notorious?) for very poor reimbursement practices.

A CT heart scan, when properly used, generates little revenue, a few hundred dollars to a scan center, barely enough to pay for a device that costs up to $2 million. However, CT coronary angiograms, in contrast, yield around $2000 per test. More importantly, they yield downstream revenues, since CT angiograms are performed as preludes to conventional heart catheterizations, angioplasty, stents, bypass surgery, etc. Now we're talking tens or hundreds of thousands of dollars revenue per test.

What puzzles me is that much of that increased cost comes out of the insurance company. Why would they support such tests if it exposes them to more costs? I'm not certain. It could be the greater pressures exerted by the big CT companies and powerful physician organizations. I seriously doubt that the insurance companies truly believe that heart scans for coronary calcium scoring are "experimental" while CT coronary angiograms are "proven." If all we did was compare the number of clinical studies that validate both tests, we'd find that the number of studies validating heart scans eclipses that of coronary angiograms several fold. Experimental? Hardly.

The smell of money by physicians eager to jump on the bandwagon of a new revenue-producing procedure is probably enough to have them lobby insurers successfully. In contrast, plain old heart scans just never garnered the kind of vigorous and vocal support, since nobody gets rich off of them.

If CT coronary angiograms are sufficiently revenue producing that my colleagues and the CT scanner manufacturers have managed to successfully lobby the health insurers, even one as financially "tight" as the one I spoke to today, well then I take that as testimony that money drives testing, as it does the behavior of hospitals, many of my colleagues, and can even force the hand of insurers.

When meat is not just meat


The edgy nutrition advocate, Mike Adams, over at NewsTarget.com came up with this scary photo tour of a processed meat product from Oscar Mayer: Mystery Meat Macrophotography: A NewsTarget PhotoTour by Mike Adams







Along with increasingly close-up photographs of this meat-product, Adams lists the ingredients in Oscar Mayer's Cotto Salami:


Beef hearts
Pork
Water
Corn syrup
Beef

Contains less than 2% of:
Salt
Sodium lactate
Flavor
Sodium phosphates
Sodium diacetate
Sodium erythorbate
Dextrose
Sodium nitrite
Soy lecithin
Potassium phosphate
Potassium chloride
Sugar


As I reconsider the role of saturated fat in diet, given the startlingly insightful discussion by Gary Taubes of Good Calories, Bad Calories, I am reminded that not all meat is meat, not all saturated fat sources are equal.

I am concerned in particular about sodium nitrite content, a color-fixer added to cured meats that caused a stir in the 1970s when data suggesting a carcinogenic effect surfaced. The public's effort to remove sodium nitrite from the food supply was vigorously opposed by the meat council and it remains in cured meats like sausage, hot dogs, and processed meats like Cotto Salami. A 2006 meta-analysis (combined analysis of studies) of 63 studies did indeed suggest that sodium nitrite was related to increased risk of gastric cancer. This argument is plausible from animal models of cancer risk, as 40 animal models have likewise suggested the same carcinogenic association.

Also, fructose? This is most likely added for sweetness. Recall that fructose heightens appetite and raises triglycerides substantially.

I personally have a natural aversion to meat. I don't like the taste, the look, smell, and the thought of what the animal went through to make it to the supermarket. But, considered from the cold, carnivorous viewpoint of the question, "Is meat okay to eat?", among the issues to consider is whether the meat has been cured or processed, and does that process include addition of sodium nitrite.

Cotto Salami and similar products are not, of course, what carnivorous humans in the wild ate. This is a processed, modified product created from factory farm animals raised in cramped conditions and fed corn and other cheap, available foods. It is not created from free-ranging animals wandering their pastures or pens, eating diets nature intended. This results in modified fat composition, not to mention hormones and antibiotics added. These are not listed on the ingredients. Wild meat does not contain fructose or color-fixers, either.

So don't mistake "meat" in your grocery store for meat. It might look and smell the same--until you look a little closer.

Don't lament no OTC mevacor

After Merck's third go at FDA approval for over-the-counter (OTC) status for its statin cholesterol drug, Mevacor (lovastatin), the FDA advisory board suggested that its request be denied. They expressed concern that too many people would not understand how the drugs would be used and that misuse would be common.

Similar sentiments were echoed by Dr. Sidney Wolfe, director of the Health Research Group at Public Citizen; the American Medical Association (though the AMA always fights anything that threatens to erode physician control over health); and the de facto spokesman for cardiologists, Dr. Steven Nissen of the Cleveland Clinic.

Although I am a supporter for tools and legislation that yield greater self-empowerment in health care to the public, there is no need to lament the failed OTC status for Mevacor. For one, Merck had no plans to reduce the price on its OTC preparation. For many people, this would have meant an increase in cost, since health insurers would surely not cover a non-prescription agent.

Second, OTC status sends the implicit message that cholesterol is the most common cause of heart disease; it is not. (Small LDL particles are the number one cause, a pattern only partially addressed by any statin drug and a pattern largely responsible for the failure of statin drugs to "cure" heart disease despite pharmaceutical manufacturer's attempts to increase doses to take up any slack in effect.)

Thirdly, you can achieve the same effect--no, a superior effect--by incorporating several simple strategies into your life. These strategies are superior to Mevacor because they do more than just reduce LDL cholesterol. You can achieve similar LDL-reducing effect to Mevacor, 20 mg, just by adding:

--2 tablespoons oat bran or ground flaxseed per day (choose flaxseed if you have sugar problems or small LDL; flaxseed contains no digestible sugars, only protein and fiber)
--Raw almonds or walnuts--at least a handful, though more is fine and will not make you fat. (It's nuts like party mixes, mixed nuts roasted in unhealthy oils, and honey-roasted nuts that make us fat, not raw.)
--Soy protein sources--probably the weakest effect of all foods listed, but a contributor that can be obtained in a variety of forms, such as tofu, soy protein powders, and soy milk.
--Other foods that reduce LDL include pectin sources (e.g., citrus rind), flavonoids (e.g., green tea); stanol esters found in butter substitute Benecol (recall that sterol-containing products like Take Control and the flood of new products on the market like HeartWise orange juice might have potential for allowing sterol esters to enter the blood, so I do NOT recommend them); and, of course, niacin.

Many of these strategies also reduce small LDL, raise HDL, reduce triglycerides, and reduce blood sugar, effects that go beyond that achieved with Mevacor. Of course, a combination strategy is not as easy as popping one pill a day, it's better for you.

I will certainly not shed any tears for Merck and its relentless efforts to gain a stronger foothold in the "transform conditions into diseases" marketing strategy, the same strategy that classifies shyness, toe fungus, and sadness into medical conditions necessitating medication. While I do generally support efforts to increase public access to strategies that increase their health care power, this one was not necessarily all good.

Damage control

Medical device manufacturer, Cordis, is launching a new marketing program to promote its Cypher drug-coated stent. You can view the details at www.CypherUSA.com , including the slick TV commercial that HeartHawk posted a blog about.

The campaign opens with:

When you open up your heart, you open up your life.

Lives hampered by angina. By shortness of breath. By restricted blood flow. These lives are changing. Because of a state-of-the-art advancement. One that can have a huge impact on arteries around your heart. The CYPHER® Stent. It can open up your arteries. Increase flow of blood and oxygen. And change your restricted life. To an active life worth living. Your new life is...

Life Wide Open


Direct-to-consumer drug advertising has been around for a few years. While it has increased awareness of drugs and the "conditions" they are supposed to treat, it has also highlighted the aggressive profit-motive of the drug industry. This is not health care for the needy and sick, but health care for profit.

So now we're beginning to see the emergence of direct-to-consumer (DTC) advertising for medical devices. There was also a brief, though unsuccessful, foray into DTC advertising for implantable defibrillators, of all things, by Medtronic a couple of years ago, also.

What is the purpose of Cordis' marketing effort? Is it to educate and inform the public who might unknowingly receive non-drug coated stents and be deprived of the restenosis-inhibiting advantage of a drug-coated device? Is it meant to right a systematic wrong, a failure of cardiologists to insert the technologically, biologically, and ethically superior coated stents?

I find that doubtful. A more likely motive is damage control. With some of the (both deserved and undeserved) negative press the drug-coated stents have received lately, Cordis, eager to protect their $20 billion (annual revenues, 2006) medical device franchise, came up with this DTC strategy. After viewing the smiling faces of people , elated because of their "wide open" arteries and lives, Cordis hopes to see people going to their doctors insisting on the stent that is "opening millions of lives," since, "when your arteries narrow, so does your life."

Cool, trendy, liberating. That's the message they wish to deliver. Cool music, beautiful people, flashy high-tech images. Who wouldn't want a Cypher stent?

Beyond damage control, it's a familiar marketing theme: You're slender, glamorous, and sexy if you drink Coke, you're a caring mother if you feed your children Jif peanut butter, you're health conscious and smart if you eat Total cereal . . . you're cool and know what you want from life if you insist on a Cypher stent.

I don't object to advertising. It's part of the capitalistic economic system. It drives awareness and grows businesses. I do get concerned when advertising is so slick and effective that the people who are not properly armed with information can be duped into thinking that they need something that they don't really need.

Or, for which there are powerful, viable alternatives. Even hear about "prevent the disease in the first place?"

Low expectations

The Framingham Risk Calculator is a standard method used by many physicians to predict risk for heart attack or death from heart disease over a 10-year period. Low-risk is defined as <10% risk of heart attack or cardiac death over 10 years; high-risk is defined as 20% or more over 10 years; intermediate-risk is in between.

Let's put it to the test:

Amy is a 53-year old businesswoman. She is 5 ft 4 inches, weighs 150 lbs. Her father had a heart attack in his early 50s followed by the usual list of hospital procedures including bypass surgery at age 60.

What is Amy's risk for heart attack or death from heart disease over the next 10 years? If we enter her data into the Framingham risk calculator, the following result is returned:

Information about your risk score:
Age: 53
Gender: female
Total Cholesterol: 198 mg/dL
HDL Cholesterol: 74 mg/dL
Smoker: No
Systolic Blood Pressure: 120 mm/Hg
On medication for HBP: No
Risk Score: 1% Means 1 of 100 people with this level of risk will have a heart attack in the next 10 years.


So, according to the Framingham calculation, Amy has <1% risk for heart attack or death from heart disease over the next 10 years. Most primary care physicians would, at most, prescribe a statin drug and talk about a reduction in saturated fat.

Thankfully, Amy didn't fall for that bit of conventional mis-information. She instead got a CT heart scan, principally because of her father's history. Her score: 117. At age 53, this put her into 90th percentile, in the worst 10% of scores for women in her age group (50-55). By heart scan criteria, her risk for heart attack is probably more like 4-5% per year, or approximately 40-50% over the next 10 years.

Let's do just a bit more math. If Amy hadn't known about her heart scan score and no preventive action was taken, the expected progression of her heart scan scores would likely be:

Start: 117
Year 1: 152
Year 2: 198
Year 3: 257
Year 4: 335
Year 5: 436
Year 6: 567
Year 7: 737
Year 8: 958
Year 9: 1245
Year 10: 1618

In fact, given Amy's starting heart scan score of 117, it is highly unlikely that she survives the next 10 years without heart attack or a fatal heart event. Yet the Framingham risk calculator puts Amy's risk at less than 1%. Could anything be more wrong?

The folly of the Framingham calculator was highlighted by a recent publication from the large Multi-Ethnic Study of Atherosclerosis (MESA), in which 3600 women (45-84 years), all of whom fell into the "low-risk" category by the Framingham calculator--just like Amy--were tracked over approximately 3 3/4 years. This study generated several observations:

1) 30% of the "low-risk" women had positive heart scan scores.
2) 5% of the "low-risk" women had scores of 300 or greater (very significant for a woman). 8.6% of these women experienced a cardiovascular event like heart attack or death over the period. Women with a heart scan score of 300 or greater had a 22-fold greater event risk compared to women with zero heart scan scores.
3) Women with heart scan scores of 1 to 299 had a cardiovascular event risk of approximately 5-fold greater risk over the period.


Across the U.S., 90% of women younger than 70 years old fall into the Framingham "low-risk" category. Yet this fiction is accepted as the prevailing standard, along with LDL and total cholesterol, for determination of risk in women and men.

In my view, using the Framingham risk calculator is a misguided, misleading path, one that will mis-classify a substantial number of women who could otherwise be spared from heart attack and catastrophe.

By the way, Amy is also the Track Your Plaque program record holder (by percentage drop), with a 63% drop in heart scan score over a 15 month period.
Look like Jimmy Stewart

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

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

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

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

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

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

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

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

    This is funny because as a 5'11" male I'm 165lbs and considered by some to be "emaciated" even though I have 10% body fat and quite a bit of muscle. I remember 45 years ago as a kid when my 6' tall father weighed 170lbs. Nobody ever called him skinny because he pretty much looked like all of his friends. He was considered normal at that time. I remember his weight at that time because he often boasted about it seeing as how he only weighed 125 lbs when he was drafted into the Navy.

    We have indeed forgotten what normal looks like.

    I think you're onto something with this 'standards' business. I'm down to 171 pounds (nearly 70 pounds!) since going on my diet. It hasn't been a FAST loss, but people who haven't seen me in a while are surprised and remark that I look like a 'stick'.

    Since when did 171 fall into the 'stick' range for a 5'4" woman? Maybe >30 BMI is thin for Kentucky.

    Note: I love Jimmy Stewart!

    Excellent post!  My question, then, is, where do we find a reliable place to find out what our desirable weight IS?  I'm not sure I trust the ones I have found on-line.  Can you recommend one?  Especially for folks over 50.  Thanks!

    "Unfortunately, many Americans have forgotten what normal looks like. Normal is certainly not a 190-lb, 5 ft 4 in woman, nor is it a 228 lb, 5 ft 11 inch man."

    So true.  Walking through the airport terminal on a visit from Asia immediately oriented me back to the US with the long chain of fast food franchises and big, waddling passengers.  A trip to Walmart to see morbidly obese people in motorized carts is a tourist attraction for Asians.  They can't believe it until they see it.

    Yes, this blog is definitely detrimental to my fat.

    For five months, I've swam, taken fish oil, cut out juice and bread from my fridge.  As a result I've lost 16 pounds, 12 beats per minute, and 3 off my blood pressure.

    I'm currently 29m 6'2 and at 184 lb, 48 bpm resting, and at 125 for blood pressure.

    It is truly scary to see how easy it is to lose weight once you know how bad certain foods are.  It is borderline addicting!

    I'm curious to see if I will hit an equilibrium or I will have to do something to stop the weight loss once I reach 175-180.

    This is so true, many of my friends think I'm extremely skinny, yet I'm at my optimal weight. My mom refuses to lose more weight,she says "people will say that I look old and sick"

    You hit the nail on the head. I too, as a 50-something year old male, was about 220 at 5'10" last year this time, and as I approached 185 mid-year, several folks asked, "Are you all right?" and "Did you intend to lose the weight?" Yet I still am not at an ideal weight for my height, and although I look slim in comparison, I still have abdominal fat that needs to go. I've also had people tell me, "You look too thin," and "Don't lose any more weight." We must recapture a sense of normal. However, during a recent visit to a Glen Ivy Spa in So. Cal. my wife and I marveled at how many grossly obese people there were sauntering around in swimsuits. We've definitely got a problem here. For me, I'd rather look like Jimmie Stewart or Jack Lalane or Art Devany, and I don't care what anyone else thinks about it!

    I had a friend say to me once, "you lost a lot of weight, are you sick 'r something?"

    I'm a 5' 9" 49 y.o. North American male and went from 192 lbs. to 168 lbs. in nine months.  This was a couple years ago. I lost most of it off my mid-section and face.  I have the incredible shrinking waist (now 30 inches.)

    I did this by simply eliminating grains, starches, and sugars.  I actually had to slightly increase my daily calorie intake (than when I weighed 192) because I too was concerned I might have been losing too much weight.

    When I share with family and friends why I look so lean, that it's from permanent grain, starch and sugar abstention, they always respond with "oh no, I can't do that"  or "how can you do that?"

    This is reassuring. I've been worrying because, since I started a heart healthy diet, I've gone from 183 lbs to 167 lbs, which is less than I weighed when I was 18 years old (170).

    Hi, Jeannie--

    There are a number of ways to determine ideal weight. BMI, though an imperfect concept, is a good starting place. Here's a BMI calculator: http://www.nhlbisupport.com/bmi/

    This gives me an idea for a future post: "What is ideal weight?"

    I won't even tell you what my Chinese in-laws think. Two English words my Chinese-speaking mother-in-law knows are "eat more." I always fend her of with with the retort "Che bao la."

    There's also the problem of finding clothes that fit. I'm a 5'11" male and weigh 152lbs. I've got a 32" waist, but when I try on 32" waist pants they fall off of me because they're really 34" (I believe this is called vanity sizing), so I look for the 30" waist pants and guess what? There are none!

    Maybe it's because I live in the South, but 30" waist pants are pretty much non-existent, and the ones that I do find are always too short.

    My wife used to think I was too skinny, but then she remembered all her Oriental friends back in California who are as skinny as I am. For them it's considered normal.

    I say revel in it!  I knew from past temporary weight loss that people would start to notice after I lost 30 pounds or so.  Since I needed to lose 70 to get to ideal weight, I also knew that those comments were nothing but signs of sucess.  We truly have adapted to a new normal in our perceptions.  The shock value does diminish over time though.  Now three years out from adopting a healthy diet (currently 6'3", 190 lbs.), I got all the comments along the way, but now people have adjusted to my new look (as have I).  Once in a while though, I see someone, usually business-related, that I haven't seen for a few years, and they're shocked.  I just enjoy it, and try to recruit them over from the dark side.

    The thing that I find interesting now is that, while I was losing people were interesting in why I was losing, and several adopted the low-carb/paleo approach with great success.  But now that I have reached an ideal weight, the memory of the previous me fades, and few see me as a potential source of healthy diet information.  I think some actually think I must be a bit of a freak for having done so well, and so there's nothing useful to be learned from me by non-freaks.

    I am another who lost weight when I dropped all grains and sugars and greatly limited high carb veges and fruits. The weight just melted away. I did not need to lose much and when I hit 20 lbs, the weight loss stopped. I have been at 120-125 for many months now. I am 5' 4". I never feel hungry eating the higher fat diet. Honestly, sometimes I do miss the junky food but not enough to eat it and jeopardize my health.

    I wonder if anyone has information on cornstarch and why it places right next to wheat as a 'food' to avoid?  I have seen a great deal of convincing argument with regard to wheat, but almost none with regard to cornstarch (other than for those who may need to closely watch blood glucose levels).  

    If anyone can lead me to more information on how it affects our organism, I would great appreciate it.

    Dr. Davis.  If you do a post on ideal weight, it might be helpful to include a discussion of muscle mass.  Many athletes are heavier than those of comparable ages in the general population, but have body fat levels that are extremely low.  There is a trade-off with weight loss and muscle loss, and I suppose a happy equilibrium at some leve.  Perhaps body fat level is a better gauge than absolute weight level, but hard to accuratley measure.  Thanks,

    I read an newspaper article about how parents in the UK didn't realise their children were obese. Yes, that's obese - not just overweight.

    We have lost sight of what it is to be of normal weight. I catch myself looking at people's sizes in old movies to remind myself of what "normal" should be.

    I really don't like the BMI indicator. First, there is no differentiation between males and females or body type. Fit males who have any kind of muscle tone or who may be big-boned will invariably have a BMI greater than 25. I'm very close even though I'm only 10% body fat.

    Instead, I think that a better measure is to ignore weight altogether and get your % body fat computed. Ideally it should be 14-17% for males and 21-24% for females.

    I too have difficulty finding pants that fit. I wear a 30" waist. Its tough to find anything smaller than a 38"-40" waist which is pretty sad.

    Based on the posts here on HeartScan and my brothers insistence Atkin's was his preferred effective weight control solution, I started eating meat again after 10 years of being a pescatarian. I put on 12 lbs in 3 months.  OK, I am not too keen on eating slabs of meat and may have gone overboard with sausage meat / chicken wings but I hope my next blood test will show an increase in HDL as a result of the added fat and lower wheat/grains

    BTW. I stopped my 20mgs crestor and got a base line several months back (too scary !). I have taken 20mgs and 40mgs crestor with the latter leading to some muscle pain but perfect LDL (60). HDL only went up with Niacin (31 to 45 )

    What I want is no more than 20mgs crestor (which gives me LDL circa 75 and I can tolerate well) and to elevate my HDL to 60 without having to eat raw cow.

    This site is a great resource. I would like to see Dr D square off against the celeb TV Dr Oz who pushes high grain diets and low saturated fat.

    I think some of the response to too skinny is because folks are faced with how 'not skinny' they are looking at those who are not.

    I'm a caucasian male, 6'2" and I've been healthily below 160.  I have a thin body.  I don't know if it's because my bones are smaller, or what, but this is normal for me.

    And, I feel for the thin folks in the south.  When we lived in TN for a few years, I had a heck of a time finding 32" waist pants.  Now that I'm back in CA, it's much easier.

    Jimmy Stewart was thought too skinny by Hollywood and the Army at the time.  When he was first signed to MGM they recognized that Stewart had an uncanny screen charisma and great star potential, but they considered him just so goofy looking that they didn't buy him having any male star sex appeal.  MGM wanted someone to compete with Tyrone Power, Clark Gable, Spencer Tracy and up and comers like Cary Grant (Grant would be a better example for you than Stewart).  Before MGM ever put Stewart in a movie they put him with one of the studio weight trainers, hoping to add some muscle to his physique.  The trainer had Stewart lifting weights and drinking a gallon of milk everyday.  After a month of this regimen Stewart had gained about three pounds, mostly of bloat.  MGM put him in a variety of bit parts but they figured he was basically useless to them so they loaned him out to Columbia for a pair of pictures, You Can't Take it with You and Mr. Smith Goes to Washington.  Stewart's star was made and he returned to MGM to make a slew of great films, Destry rides again, Philadelphia Story, & The shop Around the corner.  Stewart came from a very patriotic, midwestern family.  in 1940 Stewart basically quit his studio contract (after filming A Mortal Storm) and recognizing the world situation, he went to enlist in the Army with the idea of entering the Air Corps to train as a pilot.  He was rejected flat out because he did not weigh enough for the minimum standard to enlist.  And Stewart was 6' 3&3/4" he weighed next to nothing!  Since he was only a few lbs under, Stewart went back the next week, this time after waterloading himself.  he barely made it through the physical before bursting, but he was able to eek over that minimum weight standard by a single pound.  By the time Pearl Harbor hit, Stewart was a certified pilot and he spent most of the war continually flying bombing missions over Europe.

    Cary Grant on the other hand, would be a superb example. Grant began life as a circus tumbler, and he maintained his athleticism throughout his life.  His remarkable lack of aging until his final decade was due to his  eschewing alcohol and smoking in his private life, which was both very rare at the time and ironic considering the suave characters he played always drank and smoked.  He may also have been one of the oddball anti-sugar hollywood types (Gloria Swanson was one) that refused to eat anything with sugar in it.  But I'm not certain on that.
