Excessive Heart Procedures Makes New York Times Headline

18. August 2006 William Davis (0)

One example of flagrant cardiac procedure excess has made New York Times headlines:

Heart Procedure Is Off the Charts in an Ohio City
The number of angioplasties performed in Elyria is so high that Medicare is starting to ask questions.

(The full article can be accessed through the New York Times website at http://www.nytimes.com/2006/08/18/business/18stent.html?pagewanted=2&ei=5094&en=b81be5f43f98a99b&hp&ex=1155960000&partner=homepage)

Cardiologists in little Elyria, Ohio, about a 30-minute drive west of Cleveland, do more coronary angioplasties and insert more stents than any other location in the U.S.--four times more than the national average, three times more than the Cleveland average. They perform even more than the recently-indicted cardiologist in Louisiana, who performed twice the national average of procedures.

The Times article, part of a series about financial incentives in medical care, provides a responsible and incredibly balanced report on the situation in Elyria. I have to give them credit, because from the eyes of a colleague (myself), this looks like blatant and extreme profiteering: "cathing for dollars".

I find it outrageous that this group of cardiologists claims that they have some special insight into heart care that justifies this extraordinary reliance on heart procedures. There's bound to be variation in practice patterns, but this is so outside the norm that I believe criminal behavior will be exposed. In fact, I believe that even the "norm", or average, rate of procedures is also excessive.

This is symptomatic of the perverse equation in heart disease care. If there's money to be made in major heart procedures, who wants to bother with prevention? Programs like the Track Your Plaque program present real potential to stop coronary heart disease in its tracks for many, if not most, participants--but don't expect to hear about it from your cardiologist. Don't expect to hear about it from the increasingly hospital-employed primary care physician.

Hopefully, media exposure like that in the New York Times is just the beginning of a public re-analysis of not only what's wrong with medicine today, but recognition of the tremendous power in preventive strategies when everyone stops being so enamored with hospital-based procedures. CT-based heart scanning that ignites your heart disease prevention program is your way to dodge the mainstream obsession with procedures.

More on "Bio-identical hormones" and Wyeth Pharmaceuticals

18. August 2006 William Davis (0)

In October 2005, Wyeth petitioned the FDA, requesting that it completely ban the bioidentical alternatives that women have been using in ever-increasing numbers to achieve optimal hormone balance. With bioidentical replacement therapy clearly reducing its market share, Wyeth asked the FDA to outlaw all compounded bioidentical hormone formulations that compete with its own discredited drugs. If Wyeth is successful, then menopausal women will have no choice other than to take potentially life-threatening hormone drugs or to forgo hormone replacement therapy altogether, thus enduring the physically and emotionally debilitating effects of menopause-induced hormone depletion.

For more commentary on Wyeth Pharmaceutical's outrageous and brazen petition to the FDA to bar prescription "bio-identical" hormones, i.e., hormones that are identical to natural human forms, read Life Extension's article, Health Freedom Under Attack!
Drugmaker Seeks to Deny Access to Bioidentical Hormones

This well-researched article is in the August, 2006 issue of Life Extension Magazine. The article can also be accessed online at http://www.lef.org/magazine/mag2006/aug2006_cover_attack_01.htm

or go to www.lef.org and click on the August, 2006 issue.

The author, Dave Tuttle, details the baseless arguments raised by Wyeth, a pathetic and amazingly selfish act in the name of protecting profits for Premarin, their prescription agent. It's bad enough to be selling this worthless drug. It's even worse--criminal, in my mind--to try to stamp out our right to have a physician write a prescription for a pharmacy to mix up hormones identical to that humans produce, individualized to our needs.

If you are as angry about this as I am, please go to the Life Extension online reprint that provides access to the International Academy of Compounding Pharmacists website to send the FDA an e-mail describing your opinion, or go to www.iacprx.org.

How accurate is LDL cholesterol?

17. August 2006 William Davis (0)

Watch TV and you'd get the impression that the world revolves around LDL cholesterol: Commercials for Lipitor, Zetia, Vytorin, etc., all drugs to reduce cholesterol (total and LDL). Your doctor looks first and often only at LDL cholesterol.

If there's so much attention paid to LDL, how accurate is it? 100%? 90%? 80%?

Well, it varies widely. Occasionally, it's truly accurate, but most of the time it's miserably inaccurate . Every single day, I see people with LDL cholesterols that underestimates true (measured) LDL by 40%, 50%, and even over 100%. In other words, LDL cholesterol might be 120 mg/dl by the conventional method, but the genuine measured value might be 160 mg/dl, or even 240 mg/dl. It can be that far off--and it's not rare.

The converse can occasionally be true, though rarely in my experience: that conventional LDL overestimates true LDL. I saw someone in the office today like this, with a conventional LDL of 142 mg/dl but a true measured LDL of 115 mg/dl. I may see one or two more people like this the rest of this year.

Why is LDL so inaccurate? Several reasons:

--LDL in most labs is calculated, not measured. The "Friedewald calculation" derives LDL by substracting HDL and triglycerides (divided by 5) from total cholesterol. The higher triglycerides are, especially above 150 mg/dl, the more inaccurate the calculation becomes. As HDL drops below 50 mg/dl, this also introduces greater and greater inaccuracy.

--LDL particles vary in size. A more accurate representation and measure of LDL's dangers are therefore found in measures of LDL particle number , rather than a weight-based measure or calculation. LDL particle number can be measure as just that, LDL particle number (NMR), or as apoprotein B, the protein in LDL that occurs one apoB per LDL.

I liken conventionally calculated LDL cholesterol to a broken speedometer. You simply won't have an accurate measure of how fast you're going, though you may have a ballpark sense. But try telling that to the state patrol.

Or, as a cardiologist colleague said to me in a similar conversation about LDL: "Well, it's better than nothing!"

The lesson: If you're interested in plaque control, and control or reduction of heart scan score, you need a measured LDL, preferably LDL particle number by NMR or an apoprotein B. Another option is "direct" LDL.

Green tea: friend or faux?

15. August 2006 William Davis (0)

The www.HealthCastle.com website is a helpful website on healthy eating that sends out a free newsletter. The content is all produced by licensed dietitions and nutritionists. Although I don't agree with everything said on the site, there's still some good information.

I'm a fan of green tea. Although I believe the effects are relatively modest (weight reduction, cholesterol reduction, anti-oxidation, etc., with theaflavin and/or green tea as a beverage,) they alerted me to the fact that the Lipton Green Tea product is one you should steer clear of. Here are their comments:

"More like Soft drink than Green Tea!With 200 calories, 13 teaspoons of added sugar and a long list of artificial ingredients, Lipton Iced Green Tea is more like a bottle of soft drink than tea, in our opinion."

The Lipton website lists the ingredients:

Water, high fructose corn syrup, citric acid, green tea, sodium hexametaphosphate, ascorbic acid (to protect flavor), honey, natural flavors, phosphoric acid, sodium benzoate (preserves freshness), potassium sorbate (preserves freshness), calcium disodium edta (to protect flavor), caramel color, tallow 5, blue1.

An 8 oz serving yields 21 grams of sugar. If you drink the full 20 oz. bottle (not hard to do!), that yields 52.5 grams of sugar! You will also notice that the second ingredient listed after water is high fructose corn syrup. This ingredient, you may recall, causes triglycerides to skyrocket, causes an insatiable sweet tooth, and is a probable contributor to obesity and diabetes.

In their defense, the Lipton people do also offer a sugar-free alternative without the excessive sweeteners and empty calories.

Do the Lipton products offer the same kind of benefits from green tea catechins (flavonoids) offered by freshly brewed teas? This product has not been formally tested by an independent lab to my knowledge, though, in general, commercially prepared and bottled teas tend to have dramatically less catechin/flavonoid content compared to brewed. (The USDA website provides access to an extraordinary collection of flavonoid food content at their USDA Database for the Flavonoid Content of Selected Foods - 2003. You'll find it at http://www.ars.usda.gov/Services/docs.htm?docid=6231.)

I think the HealthCastle people got it right: Brew your own, making sure to steep for at least 3 minutes. Alternatively, a green tea or theaflavin supplement provides many of the benefits. (Theaflavin has been used in trials at doses of 375 to 900 mg per day.) An in-depth report on green tea will be coming in a future Special Report on the www.cureality.com Membership website.

The Track Your Plaque guide to getting grotesquely overweight

15. August 2006 William Davis (0)

If you'd like to gain huge quantities of weight, here's a number of helpful tips:

1) Follow the advice of food manufacturers and eat the products they label "healthy", or "heart healthy", or "part of a nutritious breakfast" etc., like Shredded Wheat cereal, pretzels ("a low-fat snack"!), low- or non-fat salad dressings.

2) Cut your morning calorie intake by skipping breakfast.

3) Hang around with other heavy people. They will confirm that it's okay to be overweight.

4) Call walking your dog "exercise".

5) Get a sedentary desk job. Use your swivel desk chair to scoot about whenever possible, rather than getting up to do things.

6) Say "I've worked hard all week long. Weekends are for relaxing, not for physical activities. I deserve a rest."

7) Eat foods without thinking about it: Eat chips while watching football, eat while on the phone, daydream over the sink.

8) Eat to provide comfort when stressed.

9) Eat foods that have sentimental value, whether or not they're good for you: Freshly-baked cakes that remind you of Mom, Pop Tarts that you used to carry in your lunchbox when you were a kid, hot dogs just like Dad would buy at the baseball stadium.

10) Cut back on sleep and generate insatiable starch cravings.

11) Stack your shelves at home with great variety. That way, you'll always have something to suit your mood.

12) Say to your spouse: "It's none of your damn business what I eat! I'm a grown man/woman!" Prove it by over-indulging in obviously unhealthy foods.

13) Tell yourself that you're just too busy to pay attention to food choices. Just grab whatever you can out of a convenience store or vending machine.

See, it's easy! And that just a start.

Of course, I don't really want you to do any of these things. But if you see yourself in any of the above, and you're struggling with weight, you should seriously rethink your approach.

Your heart scan is just a "false positive"

15. August 2006 William Davis (0)

I've seen this happen many times. Despite the great media exposure and the growing acceptance of my colleagues, heart scans still trigger wrong advice. I had another example in the office today.

Henry got a CT heart scan in 2004. His score: 574. In his mid-50s, this placed him in the 90th percentile, with a heart attack risk of 4% per year. Henry was advised to see a cardiologist.

The cardiologist advised Henry, "Oh, that's just a 'false positive'. It's not true. You don't have any heart disease. Sometimes calcium just accumulates on the outside of the arteries and gives you these misleading tests. I wish they'd stop doing them." He then proceeded to advise Henry that he needed a nuclear stress test every two years ($4000 each time, by the way). No attempt was made to question why his heart scan score was high, since the entire process was outright dismissed as nonsense.

I'm still shocked when I hear this, despite having heard these inane responses for the past decade. Of course, Henry's heart scan was not a false positive, it was a completely true positive. I'm grateful that nothing bad happened to Henry through two years of negligence, though his heart scan score is likely around 970, given the expected, untreated rate of increase of 30%.

The cardiologist did a grave disservice to Henry: He misled him due to his ignorance and lack of understanding. I wish Henry had asked the cardiologist whether he had read any of the thousands of studies now available validating CT heart scans. I doubt he's bothered to read more than the title. The cardiologist is lucky (as is Henry) that nothing bad happened in those two years.

Do false positives occur as the cardiologist suggested? They do, but they're very rare. There's a rare phenomenon of "medial calcification" that occurs in smokers and others, but it is quite unusual. >99% of the time, coronary calcium means you have coronary plaque--even if the doctor is too poorly informed to recognize it.

What's better than a heart scan?

13. August 2006 William Davis (0)

Do you know what's better than a heart scan?

Two heart scans. No other method can provide better feedback on the results of your program.

Say you've made efforts to correct high LDL; lost weight to raise HDL and reduce small LDL; added soluble fibers, nuts, and dramatically reduced wheat products; take fish oil, vitamin D, and follow a flavonoid-rich diet. Has it worked?

After a year or so of your program, that's when another heart scan can give you invaluable feedback on whether it's been successful. I tell my patients that it's relatively easy to correct lipid and lipoprotein abnormalities. The difficult part is to know when it's good enough. Is your LDL of 67 mg/dl and HDL of 50 mg/dl good enough? Another heart scan score is the best way I know of to find out.

Variation in plaque growth differs hugely from one person to another, even at equivalent lipoprotein values. Why? Lots of reasons. Humans are inconsistent day to day. Lipoproteins, being a snapshot in time and not a cumulative value, change somewhat from day to day. There's also the possibility of unmeasured, unrecognized factors that influence coronary plaque growth. We may not be smart enough to identify these hidden factors yet. But your heart scan score will incorporate the effects of these hidden factors.

Ideally, we aim for zero growth in plaque (no change in score) or a reduction. But, particularly in the first year, 10% or less plaque growth is still a good result that predicts much reduced risk of heart attack. More than 20% per year and your program needs more work--or else you know what's ahead.

Lipids are snapshots in time; heart scans are cumulative

12. August 2006 William Davis (0)

Let me paint a picture. It's fictional, though a very real portrait of how things truly happen in life.

Michael is an unsuspecting 40-year old man. He hasn't undergone any testing: no heart scan, no lipids or lipoproteins. But we have x-ray vision, and we can see what's going on inside of him. (We can't, of course, but we're just pretending.) Average build, average lifestyle habits, nothing extraordinary about him. His lipids/lipoproteins at age 40:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

At age 40, with this panel, his heart scan score is 100. That's high for a 40-year old male.

Fast forward 10 years. Michael is now 50 years old. Michael prides himself on the fact that, over the past 10 years, he's felt fine, hasn't gained a single pound, and remains as active at 50 as he did in 40. In other words, nothing has changed except that he's 10 years older. His lipids and lipoproteins:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

Some of you might correctly point out that just simple aging can cause some deterioration in lipids and lipoproteins, but we're going to ignore these relatively modest issues for now.)

Lipids and lipoproteins are, therefore, unchanged. Michael's heart scan score: 1380, or an approximate 30% annual increase in score. (Since Michael didn't know about his score, he took no corrective/preventive action.)

My point: If we were to make our judgment about Michael's heart disease risk by looking at lipids or lipoproteins, they would'nt tell us where he stood with regards to heart disease risk. His lipids and lipoproteins were, in fact, the same at age 50 as they were at age 40. That's because measures of risk like this are snapshots in time.

In contrast, the heart scan score reflects the cumulative effects of life and lipids/lipoproteins up until the day you got your scan.

Which measure do you think is a better gauge of heart attack risk? I think the answer's obvious.

11. August 2006 William Davis (0)

The recognition of the metabolic syndrome as a distinct collection of factors that raise heart disease risk has been a great step forward in helping us understand many of the causes behind heart disease.

Curiously, there's not complete agreement on precisely how to define metabolic syndrome. The American Heart Association and the National Heart, Lung, and Blood Institute issued a concensus statement in 2005 that "defined" metabolic syndrome as anyone having any 3 of the 5 following signs:

Waist size 40 inches or greater in men; 35 inches or greater in women

Triglycerides 150 mg/dL or greater (or treatment for high triglycerides)

HDL-C <40 mg/dL in men; <50 mg/dL in women (or treatment for reduced HDL-C)

Blood Pressure >130 mmHg systolic; or >85 mmHg diastolic (or drug treatment for hypertension)

Glucose (fasting) >100 mg/dL (or drug treatment for elevated glucose)

Using this definition, it has become clear that meeting these criteria triple your risk of heart attack.

But can you have the risk of metabolic syndrome even without meeting the criteria? What if your waste size (male) is, 36 inches, not the 40 inches required to meet that criterion; and your triglycerides are 160, but you meet none of the other requirements?

In our experience, you certainly can carry the same risk. Why? The crude criteria developed for the primary practitioner tries to employ pedestrian, everyday measures.

We see people every day who do not meet the criteria of the metabolic syndrome yet have hidden factors that still confer the same risk. This includes small LDL; a lack of healthy large HDL despite a normal total HDL; postprandial IDL; exercise-induced high blood pressure; and inflammation. These are all associated with the metabolic syndrome, too, but they are not part of the standard definition.

I take issue in particular with the waist requirement. This one measure has, in fact, gotten lots of press lately. Some people have even claimed that waist size is the only requirement necessary to diagnose metabolic syndrome.

Our experience is that features of the metabolic syndrome can occur at any waist size, though it increases in likelihood and severity the larger the waist size. I have seen hundreds of instances in which waist size was 32-38 inches in a male, far less than 35 inches in a female, yet small LDL is wildly out of control, IDL is sky high, and C-reactive protein is markedly increased. These people obtain substantial risk from these patterns, though they don't meet the standard definition.

To me, having to meet the waist requirement for recogition of metabolic syndrome is like finally accepting that you have breast cancer when you feel the two-inch mass in your breast--it's too late.

Recognize that the standard definition when you seen it is a crude tool meant for broad consumption. You and I can do far better.

What role DHEA?

9. August 2006 William Davis (2)

DHEA, the adrenal gland hormone, has suffered its share of ups and downs over the years.

Initially, DHEA was held up as the fountain of youth with hopes of turning back the clock 20 years. Such extravagant dreams have not held up. But DHEA can still be helpful for your program.

All of us had oodles of DHEA in our bodies when we were in our 20s and 30s. Gradually diminishing levels usually reach nearly blood levels of around zero by age 70.

In our heart disease prevention program, of course, we aim to stop or reduce your CT heart scan score. Does DHEA reduce your score? No, it most certainly does not. But it can be helpful for gaining control over some of the causes behind coronary plaque.

For instance, DHEA can:

--Help reduce abdominal fat and increase muscle mass (slightly)
--Provide more physical stamina.
--Boost mood.
--It may modestly reduce some of the phenomena associated with the metabolic syndrome (high blood pressure, high blood sugar, high insulin, low HDL, small LDL, etc.)

In my experience, people who feel better do better on their overall program. If you're always tired and run down and run out of steam by 3 pm, I won't see you riding your bicycle outdoors or at the aerobics class. But if you're bursting with energy until you put your head on the pillow, you're more inclined to walk, bike, dance, play with the kids, dance, take Tai Chi, etc.

Some downsides to DHEA: Some people experience aggression. Backing off on the dose usually relieves it. Also, sleeplessness. Taking your DHEA in the morning usually fixes it.

The dose is best tailored to your age and blood levels. People less than 40 years old should not take DHEA. The older you are, the higher the dose, though we rarely ever have to exceed 50 mg per day. If you've never had a blood level and your doctor refuses to obtain one, 25 mg per day is a reasonable dose (10-15 mg in women 40-50 years old). It's always best to discuss your supplement use, particularly agents like DHEA, with your doctor.

Boy, was I wrong!

1. August 2006 William Davis (0)

Around 10 years ago, I was talking to a balloon and stent manufacturer's representative, who was raving about some new device that was due for release to the market. Back then, the sky seemed the limit to cardiac device manufacturers, who were falling over themselves scrambling to design and market the next new device.

The angioplasty market then had ballooned (no pun intended) from nothing to a multi-billion dollar industry. Stents were just getting underway but clearly had potential for being at least as large.

But this was a time when preventive therapies were also beginning to get quite powerful. We had just gotten started doing CT heart scans and were excited about the possibilities, statin drugs were gaining evidence through clinical trials, and the power of many nutritional supplements was finally achieving validation. We were even learning the error of our prior low-fat ways.

So I broadly pronounced to the enthusiastic product representative, "In 10 years, balloons, angioplasty, and stents will occupy this little corner of cardiac care because prevention will have become so powerful. We won't talk about heart procedures. We'll talk about coronary plaque regression!"

I even advised the representative that he should consider a career change in anticipation of the coming wave of preventive strategies.

Was I ever wrong. Despite the power of heart disease prevention--which is indeed true--cardiac device and procedure technology has boomed, both in popularity as well as in revenue success. Device manufacturing and sales are hugely successful. Implanting devices into people is a hugely profitable enterprise.

Since my ill-timed comments to the salesman, Boston Scientific, a major manufacturer of stents and other cardiac devices, reported revenues of $6.2 billiondollars in 2005, a 12% increase over the prior year. Medtronic reported 2005 revenues of $11.3 billion, growing at 15% per year. Clearly, cardiac procedures are still quite popular--and profitable.

My timing was off, but not for long. The huge crest of change in preventive therapies is upon us. That's the premise behind the Track Your Plaque concept: heart disease prevention can't be found in a hospital, is not supported by cardiac device manufacturers, and is not being advocated by most cardiologists or primary care physicians. Yet the tools are getting better and better every day.

Those of you who succeed in halting or reducing your heart scan score are extremely unlikely to add to Boston Scientific's or Medtronic's revenues. Help me spread the word.

Don't forget how dangerous heart disease can be

29. July 2006 William Davis (0)

Sometimes it's easy to get smug when coronary plaque is a reversible process.

When you see people day in, day out, week in, week out, drop their heart scan scores, reversing what could be a dangerous disease, you can sometimes lose sight of just how dangerous coronary disease can be.

Whether I like it or not, I maintain a reasonably active role in hospitals out of necessity. I do need their services occasionally for people with advanced heart disease when I meet them (when regression is not the initial conversation for safety reasons), or valve disease is diagnosed, or someone shows up with congenital or heart muscle diseases. In other words, although we focus on coronary issues, there's more to heart disease than just coronary disease.

This unfortunate case just served to remind me how powerful coronary disease can be. Elizabeth, an active 67-year old, finally came to the hospital after suffering 6 months of chest pain and increasing breathlessness. She hated hospitals and hadn't seen a doctor in 30 years since she was successfully treated for cancer.

In those 30 years, she'd been quite active with family and a small business. But she also smoked 2 packs of cigarettes most of those years.

After she was admitted to the hospital, it became clear that Elizabeth had experienced one, if not several, heart attacks along the way. The entire front 2/3 of her heart was non-functional. If that wasn't bad enough, two of her heart valves were severely diseased and dysfunctional: Her aortic valve barely opened (aortic valve "stenosis", or stiffness) and the mitral valve leaked severely (mitral valve "insufficiency", or leakiness). All of this was confirmed with conventional testing in the hospital, including a heart catheterization.

Elizabeth ended up in emergency surgery--very unusual, by the way, for valve surgery of the sort she had--but died in the first few hours after her procedure. Her heart had simply been too damaged from her heart attacks, and the extraordinary stress of surgery that included two valves was too much. She died on the ventilator.

Coronary disease is a very serious matter. When I see cases like Elizabeth, it boosts my commitment to tell everyone that heart disease--when identified early enough--is a controllable, preventable, even reversible process. For poor Elizabeth, she was much too far down the path of severe, irreversible disease that control or reversal was simply not an option. She was in imminent danger of dying even upon arrival.

It's exciting yet sometimes frightening to know what you have in your hands: The means to control this monster called coronary disease. Use it wisely. But don't lose sight of what it can do it you permit it to grow, fester, and explode.

How many ways can you disguise sugar?

28. July 2006 William Davis (0)

I came across this shockingly silly report on AOL, who obtained their info courtesy Health Magazine:

The Best New Healthy Foods for Busy People
from Health

The foods on their list:

Kettle Brand Bakes Hickory Honey BBQ--the healthy claim is based on the lack of trans-fatty acids and low-fat.

Post Healthy Classics Raisin Bran Cereal Bars, Cranberry--Likewise, low-fat, sweet, and addictive means healthy to these people.

Amy’s Mediterranean Pizza With Cornmeal Crust --Please!!

Horizon Organic Colby Cheese Sticks --Because it's made by cattle without use of growth hormone or antibiotics, they declare this healthy. I guess we can ignore the saturated fat content and high total fat content.

100% Whole Grain Chips Ahoy! Cookies --You mean we can add the bran back to wheat products and make it healthy?!

This kind of mass-market marketing trickery leaves me incredulous. Don't believe it for a moment. This is typical of the food industry: Take one aspect of nutrition that is truly healthy, such as high-fiber, or low-fat, or organic. Then add undesirable, unhealthy ingredients. The current fad is to add lots of sugar and or sugar-equivalents (usually flour and other wheat products). Because there's one healthy ingredient, they'll call the end-product healthy, too.

If you want to see what health looks like if you indulge in "healthy" products like this, just look up and down the grocery aisles at your neighborhood grocery store. You're likely to see the results: Gross obesity, diabetes, and arthritis.

You won't, of course, see the huge acceleration of growth in coronary plaque, but it's there, ticking away.

To remind us what ideal body weight is: Watch an old movie!

26. July 2006 William Davis (0)

Jack was skeptical. At 273 lbs, 5 ft 11 inches, he felt that he was "just right".

"I feel fine. I don't see why you think I should lose weight," he declared. "In fact, when I lost 25 lbs a couple of years ago, everyone said I was too skinny!"

I showed Jack why: He had an HDL of 35 mg/dl, small LDL (over 90% of all LDL particles), an elevated blood sugar of 123 mg/dl (diabetes is officially 126 mg/dl or greater), high blood pressure, and increased inflammation (C-reactive protein). These were all manifestations that his body weight was too much for it to handle.

So I told Jack that we've all forgotten what ideal weight should look like. Our perception of "normal" has been so utterly and dramatically distorted by the appearance of our friends, family, co-workers, and other people around us that we've all lost a sense of what a desirable weight for health should be.

So I suggested to Jack that, if he wanted to rememember what ideal weight is and what people are supposed to look like, just watch old movies.

Old movies, like the 1942 production of Casablanca, or the 1952 production of Singin' in the Rain, show the body build that was prevalent in those days. Look at Humphrey Bogart or Gene Kelly--men with average builds, weighing 140-160 lbs--that's how humans were meant to look.

A report this morning on the Today Show showed the "after" photos of several people following bariatric (weight reduction) surgery. The "after" pictures, from the perspective of ideal weight and ideal health, remain hugely overweight.

We need to readjust our perceptions of weight. The average woman in the U.S. now weighs 172 lbs(!!!). Don't confuse average with desirable.

Diabetes is a choice you make

24. July 2006 William Davis (0)

Tim had heart disease identified as a young man. He had his first heart attack followed by a quadruple bypass surgery at age 38. Recurrent anginal chest pain and another small heart attack led to several stents over three procedures in the first four years after bypass.

Tim finally came to us, interested in improving his prevention program. You name it, he had it: small LDL, low HDL (28 mg/dl), lipoprotein(a), etc. The problem was that Tim was also clearly pre-diabetic. At 5 ft 10 inches, he weighed 272 lbs--easily 80 or more pounds overweight.

Tim was willing to make the medication and nutritional supplement changes to gain control over his seeminglly relentless disease. He even turned up his exercise program and lost 28 lbs in the beginning. But as time passed and no symptoms recurred, he became lax.

Tim regained all the weight he'd lost and some more. Now Tim was diabetic.

"I don't get it. I eat good foods that shouldn't raise my insulin. I almost never eat sweets."

I stressed to Tim that diabetes and pre-diabetes, while provoked acutely by sugar-equivalent foods (wheat products, breads, breakfast cereals, crackers, etc.), is caused chronically by excess weight. If Tim wants to regain control over his heart disease, he needed to lost the weight.

Unlike, say, leukemia, an unfortunate disease that has little to do with lifestyle choices, diabetes is a choice you make over 90% of the time. In other words, if you become diabetic (adult variety, not children's variety) as an adult, that's because you've chosen to follow that path. You've neglected physical activity, or indulged in too many calories or poor food choices, or simply allowed weight to balloon out of control.

But diabetes is also a path most people can choose not to take. And it is a painfully common choice: Nearly two-thirds of the adults in my office have patterns of pre-diabetes or diabetes when I first meet them.

Let me stress this: For the vast majority of adults, diabetes is a choice, not an inevitability.

I'll call the doctor when I feel bad!

24. July 2006 William Davis (0)

Max just had his heart scan. He sat down with the x-ray technologist at the work console while she pointed out the white areas in his coronary arteries that represented plaque.

"It looks like you're going to have a fairly high score," the technologist commented. "The final report will be available after one of our cardiologists reviews your images."

Max shrugged. "Well, I don't feel anything. I'm always running around with work, with my kids, stuff like that. That's better than any stress test. I guess I'll worry about it if it starts to bother me."

You'd be surprised how common this view remains: If it's not bothering you, then just forget about it. It's easy to do, since you have no symptoms, nothing to impair your physical activities. But what are the potential consequences of ignoring your heart scan? Here's a few:

--Prevention and plaque reversal efforts are most effective the earlier you start. From a heart scan score viewpoint, the lower your starting score, the easier it is to gain control over it. More people will succeed in reducing their score when the starting score is lower.

--The role of prevention of heart disease instantly crystallizes when you know your score. Your LDL cholesterol of 142 mg/dl or HDL of 41 mg/dl no longer seem like just numbers of borderline signficance. Instead, they become useful tools to gain control over plaque. They cast your numbers in a new and clear light.

--Knowing your heart scan score today gives you a basis for comparison in future. Your score of, say 250, today, can be 220 in one year. Without your preventive efforts, it will be 30% higher: 325. That's a big difference!

--Sudden death or heart attack--can occur in up to 35-40% of people with hidden heart disease--without warning.

Don't even bother getting a heart scan if you're going to ignore it. I've said it before and I'll say it again: A heart scan is the most important health test you can get--but only if you do something about it.

Coenzyme Q10 and statin drugs

23. July 2006 William Davis (0)

Although drug manufacturers claim that muscle side effects from statin drugs occurs in only around 2% or people or less, my experience is very different.

I see muscle weakness and achiness develop in the majority of people taking Lipitor, Crestor, Zocor, Vytorin, etc. I'd estimate that nearly 90% of people get these feelings sooner or later.

Thankfully, the majority of the time these feelings are annoyances and do not lead to any impairment. Full-blown muscle destruction is truly rare--I've seen it once in over 10 years and thousands of patients.

The higher the dose of statin drug and the longer you take it, the more likely you're going to have muscle aches.

I experienced a strange phemomenon myself today. I worked outdoors for about 4 hours, pulling weeds, digging in the dirt, spreading topsoil. (I have an area of overgrowth in the front yard.) Admittedly, I worked pretty hard and it was a warm, humid day.

I was sore, as you'd expect at age 49. But, much more than that, I was exhausted--my muscles ached and I had barely enough strength to get up the stairs.

Hoping for some relief, I took an extra dose of coenzyme Q10. I usually take 50-100 mg per day. Today, when I felt this overwhelming muscle fatigue, I took an additional 200 mg. Within 10 minutes, I felt a surge of energy. It was, in fact, a perceptible, quite dramatic feeling.

I am thoroughly convinced, through my own experiences on Lipitor (I have a high LDL particle number despite a healthy lifestyle, among other abnormalities), and the experiences of many other people, that coenzyme Q10 can be an extremely useful tool to minimize the muscle aches and weakness of the statin drugs.

If you do indeed need to take one of these agents, coenzyme Q10 is worth knowing about. Supplementing coenzyme Q10 has, for me, been a real lifesaver. For many people, LDL reduction is a crucial part of their heart scan score control program. In my experience, many of them would not be able to take the drug without eozyme Q10.

Blast your LDL with oat bran and almonds

21. July 2006 William Davis (1)

Nearly all of us can use an extra boost in reducing LDL cholesterol. We have a large number of people, in fact, who have reduced LDL into the Track Your Plaque range of 60 mg/dl or less without the use of statin cholesterol-reducing drugs.

Oat bran is among my favorite ways to reduce LDL. Three tablespoons per day is a really effective method to drop your LDL around 20 points. There's twice the beta glucan (soluble, or "viscous", fiber)in oat bran, as compared to the more popular oatmeal. Add oat bran to anything you can think of: yogurt, cottage cheese, vegetarian chili, oatmeal, top desserts with it, etc. Some people struggle to find oat bran in the grocery store. Most health food stores that sell bulk products will have oat bran, usually less than a $1 per pound. Many grocery stores will also have an oat bran hot cereal along with the Cream of Wheat and oatmeal. That's okay, provided the only ingredient is oat bran--no added sugars, etc.

Another dynamite method to reduce LDL 10-20 points is adding raw almonds to your daily food choices. One or two handfuls per day works great. We find it at Sam's Club for around $12.99 for a 3 lb. bag. The plentiful fibers and monounsaturates in almonds keep you full and satisified, take the edge off your sweet tooth, and even blunt the blood sugar rise caused by other foods.

Both these foods are also great ways to combat the metabolic syndrome. Since both fiber-rich oat bran and almonds slow the release of sugars into the blood, blood insulin level is also reduced. This results in a happy cascade of less small LDL, increased HDL, and a reduction in inflammation.

All these wonderful effects contribute to inching you closer to success: dropping your heart scan score.

Pre-diabetes with normal blood sugar

20. July 2006 William Davis (0)

We pay special attention to pre-diabetes, in all its varied manifestations, in the Track Your Plaque program. This is because these factors are potent instigators of coronary plaque growth.

Early in the Track Your Plaque program we ignored these measures. After all, this is a program for heart disease risk reduction, not for mangement of diabetes. But we saw explosive rates of plaque growth when pre-diabetic factors were not controlled--even when cholesterol and related factors were under excellent control.

It became increasingly clear that factors associated with pre-diabetes needed to be managed, as well. This includes small LDL, increased blood sugar, high blood pressure, increased inflammation (as CRP).

Many people, however, have normal blood sugars (100 mg/dl or less) with a high blood insulin level (>10 microunits/ml). (This blood test is available in most laboratories.) This means that they have early resistance to insulin. The pancreas, the source of insulin, responds to the body's unresponsiveness to insulin by increasing insulin production.

Increased blood insulin with normal blood sugar will drive production of higher triglycerides, a drop in HDL, creation of small LDL, and inflammation--and coronary plaque growth, as evidenced by increasing CT heart scan score.

Blood insulin levels can be very effectively dropped by weight loss; exercise; reduction of processed carbohydrates like breads, pretzels, and breakfast cereals; and increased raw nuts and oat products; and vitamin D replacement to normal levels. Drug manufacturers are desperately trying to make this a mandate for drug treatment (Actos, Avandia), but are encountering resistance, since most people without overt diabetes don't want to take diabetic medication (rightly so!).

You and your doctor should consider insulin as a factor to track, especially if you have small LDL, low HSL, or high triglycerides, or any of the other manifestations listed above.

Sometimes small LDL is the only abnormality

19. July 2006 William Davis (0)

Janet is a 58-year old schoolteacher. At 5 ft 3 inches and 104 lbs, she had barely an ounce of fat on her size-2 body. For years, Janet's primary care physician complimented her on her cholesterol numbers: LDL cholesterol values ranging from 100 to 130 mg/dl; HDL cholesterol of 50-53 mg/dl.

Yet she had coronary disease. Her heart scan score: 195.

Lipoprotein analysis uncovered a single cause: small LDL. 95% of all of Janet's LDL particles were in the small category. What was surprising was that this pattern occurred despite her slender build. Weight is a powerful influence on the small LDL pattern and the majority of people with it are overweight to some degree. But not Janet.

How did she get small LDL if she was already at or below her ideal weight? Genetics. Among the genetic patterns that can account for this pattern is a defect of an enzyme called cholesteryl-ester transfer protein, or CETP. This is the exact step, by the way, that is blocked by torcetrapib, the new agent slated for release sometime in future (The manufacturer, Pfizer, is apparently going to sell this agent only packaged in the same tablet as Lipitor. This has triggered an enormous amount of criticism against the company and they are, as a result discussing marketing torcetrapib separately.)

Also note that Janet had a severe excess of small LDL despite an HDL in the "favorable" range. (See my earlier conversation on this issue, The Myth of Small LDL at http://drprevention.blogspot.com/2006/06/myth-of-small-ldl.html.)

With Janet, weight loss to reduce small LDL was not an option. So we advised her to take fish oil, 4000 mg per day; niacin, 1000 mg per day; vitamin D, 2000 units per day; use abundant oat bran and raw almonds, both of which suppress small LDL. This regimen has--surprisingly--only partially suppressed her small LDL pattern by a repeat lipoprotein analysis we just performed. We're hoping this may do it, i.e., stop progression or reduce her heart scan score.

The lesson: Small LDL is a very potent pattern that can be responsible for heart disease, even if it occurs in isolation. And, contrary to conventional thinking, small LDL can occur as an independent abnormality, even when HDL is at favorable levels.

Are you a skinny fat person?

29. September 2006 William Davis (1)

AT 186 lbs. and 5 feet 10 inches, Doug did not regard himself as overweight. Sure, he had a little extra "love handles", a small bulge in the belly and a waist of 34 inches. But he was by no means fat, particularly compared to most of his friends, neighbors, and co-workers, many of whom were 50-100 lbs heavier.

But examine Doug's lipoprotein patterns and, if you didn't know what he looked like, you'd guess that he's at least 50 lbs or more overweight. His prominent patterns included low HDL, small LDL, high triglycerides, the after-eating IDL, and borderline high blood sugar of 116 mg/dl. His blood pressure usually ranged around 138/82.

In other words, Doug is among the 5-10% of people who have most of the features of the so-called "metabolic syndrome", but don't look the part. They usually (though not always) have a modest excess of visceral abdominal fat. While some people have to be 100 lbs overweight before they express these patterns, someone like Doug could do it with minimal excess weight, sometimes as little as 5-10 lbs.

Several specific genetic patterns can account for this exagerrated sensitivity to weight, but the solutions remain much the same. Heightened sensitivity to processed carbohydrates, particularly those containing wheat, is commonly present. A sharp reduction in processed carbohydrates like breads, breakfast cereals, and pretzels yields a huge benefit. Reduction in weight, of course, can also yield marked improvement in these patterns. This means that Doug should consider achieving his truly ideal weight of <175 lbs and become a truly skinny skinny person. Though his patterns might not be fully corrected, he will see substantial improvement across the board.

These patterns are also potent triggers for coronary plaque growth. Correction of low HDL, small LDL, etc. is crucial if you are to seize hold of your heart scan score.

Heart disease "reversal" gives health a bad name

28. September 2006 William Davis (0)

Put the search phrase "reverse heart disease" into your internet search engine, and you'll uncover an astonishing range of sites, all making extravagant promises.

The treatment programs offered range from the bizarre (colonic irrigation, magnetism, etc.), to centers using conventional approaches like statin drugs and low-fat diets, to sites that make lofty predictions with few unique tools (slash the fat and heart disease dissolves).

95% or more of the sites you turn up are clearly pandering to the unknowing, the unsophisticated, the hopeless, or other helpless niche groups. Homeopathic preparations, chelation, magnical combinations of herbals, you name it, you'll find it attached to claims for heart disease reversal.

I've seen people use many of these treatments. Is there any effect on the rate of increase of the heart scan score? Do they impact on the 30% per year expected rate of increase? Absolutely not.

Unfortunately, this gives anyone practicing truly effective methods to reverse coronary plaque a bad name. Just associating with this suspect group of "practitioners" can make us look bad--guilt by association.

Whenever someone claims to have the secret of heart disease reversal, I ask "Can you prove it?" Show me some evidence. It doesn't necessarily have to be $30 million drug company sponsored study, but some evidence of effectiveness should be available. The only thing we should take on faith is our religion, not our health care.

Our growing number of people who have, indeed, reversed their heart scan scores--reversed heart disease--to me is persuasive evidence of the value of the Track Your Plaque approach. Not foolproof, not 100%, but the best damned approach I'm aware of, by a long shot.

Trans fats to be banned

27. September 2006 William Davis (0)

Sometimes good may come from legislation.

The City of New York is contemplating a ban on trans-fat use by restaurants, bakeries, and other food establishments in preparation of their foods. (Trans-fats are also known as hydrogenated fats.)

At this point, I believe it's unclear, should this pass, what the response will be. If food preparers turn to butter, that's not much better. (Don't get fooled by the non-sensical argument of which is better, butter or margarine--they're both terrible.) Subtracting hydrogenated fats will no doubt cause major disruption of food preparation habits. It may even increase the cost of food slightly.

I believe that the true positive effect of this situation, however, will be the tremendously heightened awareness it will raise in the public, both in New York and elsewhere, on just how bad and pervasive trans-fats are. It may increase awareness that foods like donuts and pastries are not just about excessive quantities of sugars, but also trans-fat content.

If you're already a Track Your Plaque follower, you already know that the easiest way to dodge trans-fats in your diet is to minimize your use of processed foods--the cellophane-wrapped, pulverized, dried, just-add-water, microwavable and ready-to-eat foods that line supermarket shelves. Trans-fats are purely man-made. You won't find them--not a stitch--in green peppers, lettuce, olive oil, almonds. . .unprocessed foods. Watch for an in-depth report on trans-fats on the Track Your Plaque website in which we will detail the scientific evidence behind this movement, how to recognize when foods contain trans-fats, etc.

Back to basics!

27. September 2006 William Davis (0)

Harold is energetic and highly motivated. His heart scan score of 997 really threw him for a loop: his view of himself as a healthy, slender, 58-year old clearly needed revision.

So Harold set himself on a quest to find new ways to help him deal with his heart disease risk. He enrolled in the Track Your Plaque program. Unfortunately, he skimmed through the information but didn't really put much of it to use.

Instead, he wanted the "secret" information that other people didn't know about, "insider" information that couldn't be found in magazines, wasn't know by doctors.

He'd read that hawthorne was useful for opening coronary arteries, so he bought hawthorne at the health food store. He read that coenzyme Q10 was a little know way to strengthen the heart, so he added that. A Chinese doctor in town was advertising chelation therapy that "dissolved plaque". He subscribed to a once-a-week intravenous infusion at the doctor's holistic clinic of Eastern medicine. He'd heard that testosterone opened up arteries, so he purchased a preparation of chrysin, horny goat weed, yohimbine, and saw palmetto. He was suspicious of many conventional medicines, but he didn't want to ignore his LDL cholesterol of 172 mg/dl. So he added guggulipid and a combination cholesterol-reducing product that contained about 10 ingredients.

Harold pursued his quest, often adding new agents that came with promising stories. One year later, Harold eagerly got another heart scan, certain that his extraordinary efforts were sure to yield a dramatic drop in his heart scan score. The score: 1372, a 37% increase.

Harold was therefore several thousand dollars poorer and several steps closer to taking the plunge, allowing a potentially fatal disease to cut his life short.

The message: There's no need to re-invent the wheel. There are no top-secret ways to reverse atherosclerotic plaque.

Don't neglect the basics. You can't do calculus until you learn how to add, subtract, and divide. From a heart scan score reducing perspective, achieving 60-60-60 in basic lipids, normalizing blood pressure and blood sugar, identifying any hidden lipoprotein patterns like small LDL and Lp(a), losing weight to your ideal weight, taking fish oil, normalizing vitamin D blood levels to 50-70 ng/ml--these are the necessary prerequisites to achieve control over your coronary plaque and stop the increase in your heart scan score.

You don't need to waste your time with the rants of some supplement-hawker eager to sell you the next cure for heart disease. I'm often amazed at the number of people who do so yet have never even taken care of someone with heart disease. Would you allow someone to try and repair your car if they've never actually laid their hands on an engine before? Then why would you entrust such a person with your health?

The Track Your Plaque approach is not fool-proof, but it's the best there is by a long shot.

I don't care about hard plaque!

25. September 2006 William Davis (10)

I ran into a cardiology colleague this weekend. He was aware of my interest in CT heart scanning and plaque reversal.

Out of the blue, he declared "I don't care about hard plaque! I only care about soft plaque." He then proceeded to describe to me how everyone--EVERYONE--needs a CT coronary angiogram to identify "soft plaque".

Is there any truth to this view? Are we only identifying "hard plaques" by focusing on calcium and calcium scores on simple CT heart scans?

Several issues deserve clarification. First of all, CT heart scans don't identify hard plaque. They identify total plaque. Because calcium is a component of the majority of atherosclerotic plaque, comprising approximately 20% of its volume, a calcium "score" can be used to indirectly quantify total plaque, both "hard" and "soft".

Anyone cardiologist who performs a lot of the procedure, intracoronary ultrasound, knows that most human plaque is also not purely soft or hard, it is mixture of both. (I've been performing this procedure since 1995.) Quantifying only soft or only hard plaque is therefore only possible in theory, not in practice.

I believe my colleague does have a valid point in one regard, however. There is indeed a small percentage of people, probably around 5% of all people who have CT heart scans, who have scores of zero yet have a modest quantity of pure "soft" plaque. These people may be misled by having a zero score. How can these people benefit from better information?

Several ways. First, people like this tend to have very high LDL cholesterols, generally 180 mg/dl or greater. They may have a very worrisome family history, e.g., father with heart attack in his 30s or 40s. This small proportion of people with zero heart scan scores may benefit from receiving X-ray dye with their heart scan, i.e., a CT coronary angiogram. Keep in mind that we're assuming everyone is without symptoms, also. If symptoms are part of the picture, everything changes.

But should everybody get a CT coronary angiogram? I don't believe so. A CT coronary angiogram involves far more radiation exposure, greater expense (usually $1800 to $4000), and, with present day technology, does not yield quantitative (measurable) information that is useful for longitudinal use for repeated scans. You don't want to undergo yearly CT coronary angiograms, for instance.

Stay tuned for more on this issue. In the meantime, I continue to try and inform my colleagues about what is right, what is wrong, what is preferable for patient safety and yields truly empowering information, and try to impress on them that the practice of cardiology is not just about enriching their retirement accounts.

Try an experiment in a wheat-free diet

23. September 2006 William Davis (1)

Years back, I'd heard some people argue that wheat-based products were detrimental to health. At the time, I thought they were nuts. After all, wheat is the principal ingredient in a huge number of American staples like breakfast cereals and bread.

What changed my mind was the low-fat movement of the 1980s and 1990s. Proponents of low-fat diets claim that heart disease is caused by excess fat in the diet. A diet that is severely restricted in fat therefore might cure or reverse heart disease.

But low-fat diets evolve into high-carbohydrate diets. This nearly always means an over-reliance on wheat products. People will say to me "I had a healthy breakfast: shredded wheat cereal in skim milk and two slices of whole wheat toast." Yes, it is low-fat, but is it healthy?

Absolutely not. Followers of the Track Your Plaque program know that low-fat diets ignite the formation of small LDL particles (a VERY potent trigger of coronary plaque growth), drops HDL, raises triglycerides, causes resistance to insulin and thereby diabetes, raises blood pressure. They also make you fat, with preferential accumulation of abdominal visceral (intestinal lining) fat.

Look at people with gluten enteropathy, a marked intolerance to wheat products that results in violent bowel problems, arthritis, etc. if unrecognized. These people, if the diagnosis is made early, are strikingly slender and commonly unusually healthy otherwise. There's a message here.

If you need convincing, try an experiment. Eliminate--not reduce, but eliminate wheat products from your diet, whether or not the fancy label on the package says it's healthy, high in fiber, a "healthy low-fat snack", etc. This means no bread, pasta, crackers, cookies, breads, chips, breading on chicken, rolls, bagels, cakes, breakfast cereal...Whew!

You won't be hungry if you replace the lost calories with plentiful raw almonds, walnuts, pecans, sunflower and pumpkin seeds; more liberal use of healthy olive oil, canola oil and flaxseed oil; adding ground flaxseed and oat bran to yogurt, cottage cheese, etc.; and more lean proteins like lean beef, chicken, turkey, and fish.

I predict that, not only will you lose weight, sometimes dramatically, but you will feel better: more energy, more alertness, sleep better, less moody. Time and again, people who try this will tell me that the daytime grogginess they've suffered and lived with for years, and would treat with loads of caffeine, is suddenly gone. They cruise through their day with extra energy.

Success at this can yield great advantage for your heart scan score control and reversal efforts. It will give you greater control over small LDL and pre-diabetic patterns, in particular.

Bigger, faster plaque reversal

22. September 2006 William Davis (0)

Perhaps it's too early to tell whether it's true, but believe that we're seeing coronary plaque reversal--i.e., reduction of CT heart scan score--that is BIGGER and FASTER than ever before. We are now witnessing 20-30% reductions in score, even in the first year.

Early in our experience, I was thrilled with a slowing of plaque growth. Recall that coronary plaque grows at the rate of 30% per year. We would often seen slowing to 10-15% per year in the first year, then a levelling off to little or no increase in the 2nd or 3rd year. Regression, or reduction of score, was less common.

Now, with some further tweaking of our program, we are seeing these large magnitudes of coronary plaque reversal routinely. Not in everybody, of course. There are exceptions that mostly includes people who are less motivated and occasional people with more difficult to control lipoprotein patterns.

I believe that part, or perhaps most, of our recent success is from normalizing blood levels of 25-OH-vitamin D3 levels to 50-70 ng/ml. I'm unable to tell you why this occurs, but I am convinced that it has added huge advantage. Raising blood vitamin D levels to normal carries enormous implication: reduction of colon and prostate cancer risk, reduction of blood pressure, sensitization to insulin, prevention of arthritis and multiple sclerosis, and--I believe--control over coronary plaque calcification and growth.

Watch for a profile of one of our latest success stories, a physician who was experiencing 20% per year plaque growth three years in a row until he followed the Track Your Plaque approach and promptly experienced an 18% reduction in heart scan score.

I need to do more procedures!

22. September 2006 William Davis (0)

I sat next to a cardiology colleague of mine last evening at a dinner. He was lamenting the fact that, because of changes in hospital affiliations of his several-member cardiology group, he'd seen a drop in the volume of heart catheterizations he was performing.

"I'm used to doing 5 cases a day! Now I'm down to 3 or 4 a day." He went on to tell me how he's working to increase his volume. "I'm branching out into doing carotid stents and anything I can find in the legs." He also described how he was cultivating referring physicians to send him more procedural patients.

Now, this colleague, I believe, is a hard-working, conscientious physician. But his attitude reflects the perverse logic of many physicians: I need to do more procedures, not because it benefits patients, but because that's what I want to do--to be busy, make more money, acquire more experience, build my ego, etc.

Doing more procedures has nothing to do with an altruistic goal of doing more good for society. It is purely for selfish reasons. Beware of this shockingly common, pervasive attitude. There's a proper time and place for heart procedures, or any procedure, for that matter. But feeding your doctor's ambitions is not a good reason.

Fast food and quick plaques

20. September 2006 William Davis (0)

Such was the title of Dr. William Roberts' editorial back in 1987 discussing the health effects of fast foods.

If you need a graphic illustration of the extraordinarily damaging health effects of fast foods, take a look at trends in mainland China. A recent editorial in the American Journal of Cardiology written by Dr. Tsung Cheng of George Washington University makes several points:

--The popularity of fast food in China is booming, with Chinese now more likely than Americans to eat in a fast food restaurant. Each week, 41% of Chinese eat in a fast food restaurant at least once, compared to 35% in the U.S.

--Average total cholesterol levels have skyrocketed from 150 mg/dl in 1958 to 230 mg/dl in 2003.

--50% of Chinese with normal blood pressure in 1992 are now hypertensive.

--Hospitalization for heart disease rose from the 5th most common diagnosis to #1, now constituting nearly 50% of all hospital admissions.

McDonald's and KFC dominate the fast food landscape in China, but up and coming competitors are growing at exponential rates. A media conversation that will surely be reported in the near future is the boom in obesity and diabetes in China as these trends express themselves in weight gain, as it has in the U.S.

I hope you've all seen the entertaining but frightening documentary, Supersize Me chronicling the travails of 30-something Morgan Spurlock as he eats all his meals for one month at McDonald's restaurants in 20 cities. Though focusing on McDonald's, the movie is about a lot more than that. It paints a picture of how fast food as well as food manufacturers in general have changed--distorted--our eating habits.

If you haven't yet seen it, I would urge you to do so and watch it with the rest of the family. My kids (ages 8, 12, and 14) were shocked (and entertained) and they haven't set food in a fast food restaurant since.

But fish oil is too drastic!

20. September 2006 William Davis (0)

Ted is a 74-year old physician, still conducting a busy practice. He came to me because of some vague fatigue and breathlessness. He also got himself a CT heart scan. His score: 1277.

When he came to my office, he clearly became breathless with just minimal effort. A stress test confirmed an area of much reduced blood flow to the front of his heart muscle. A heart catheterization identified a severe blockage of 95% in the left anterior descending artery and a stent was inserted. This resulted in relief of Ted's symptoms.

When Ted returned to the office after his discharge from the hospital, I advised him that some major changes in his prevention program were overdue. "After all, Ted, you were lucky this time. You were provided some warning. It doesn't always work that way." So I advised Ted to make a number of changes in his diet (he was following an old-fashioned, and quite self-destructive, low-fat diet), have lipoproteins assessed to identify hidden causes of coronary plaque, and take fish oil.

"Fish oil? I don't think so. That's pretty drastic!" he exclaimed. He felt that all the nutrition he needed was contained in the food he ate. Even after several lipoprotein abnormalities were uncovered like small LDL and excessive after-eating (post-prandial) patterns, he still resisted any changes. "I'm going to just wait and see how I feel. But I will take aspirin."

Such is the state of mind of the older physician: procedures are okay, low-fat diets prevent heart disease, and the Beatles are touring America. But fish oil? No way!

Unfortunately, Ted's attitude encapsulates the attitudes of many of my medical colleagues who don't share the excuse of age. They still practice the woefully outdated ways of physicians like Ted, clinging to notions of "balanced diets", nitroglycerin representing a rational treatment for coronary disease, and adequate rest being curative for heart conditions.

The world is changing. We're entering an exciting age of self-empowerment. The ridiculous notions of health practiced in the last half of the 20th century are withering and dying. Poor Ted. He must view the current healthcare landscape as increasingly incomprehensible to a guy who started out delivering babies at home. Perhaps, in some respects his world was better. But, in coronary disease prevention, attitudes like this need to go the way of steam engines and racial segregation--good riddens!
