I don't mean to beat this discussion to a pulp, but looking back over the comments posted on www.theHeart.org forum, I am so deeply impressed with Dr. William Blanchet's grasp of the issues, that I posted his articulate and knowledgeable comments again.

Here is one post in which Dr. Blanchet, in response to accusations of trying to profit from heart scans, provides a wonderful summary of the logic and evidence behind the use of heart scans as the basis for heart disease prevention.

Yes, I have seen a dramatic reduction in coronary events.

Of 6,000 active patients, 48% being Medicare age and over, I have seen 4 heart attacks over the last 3+ years. 2 in 85 year old diabetics undergoing cancer surgery, one in a 90 year old with known disease and one in a 69 year old with no risk factors, who was healthy, and had never benefited from a heart scan.

The problem with coronary disease is that we rely on risk factors. Khot et al in JAMA 2003 showed that of 87,000 men with heart attacks, 62% had 0 or 1 major risk factor prior to their MI. According to ATP-III, almost everyone with 0-1 risk factors is low risk and most do not qualify for preventive treatment. EBT calcium imaging could identify 98% of these individuals as being at risk before their heart attack and treatment could be initiated to prevent their MI.

Treating to NCEP cholesterol goals prevents 30-40% of heart attacks. Treating to a goal of coronary calcium stability prevents 90% of heart attacks. Where I went to school, a 40% was an F. Why are we defending this result instead of striving to improve upon it? I am not making this up, look at Raggi's study in Arteriosclerosis, Thrombosis, and Vascular Biology 2004;24:1272, or Budoff Am J Card.[I believe it's the study Dr. Blanchet was referring to.]

I strongly disagree with the assertion that the stress test is a great risk stratifier. Laukkanen et al JACC 2001 studied 1,769 asymptomatic men with stress tests. Although failing the stress test resulted in an increased risk of future heart attack, 83% of the total heart attacks over the next 10 years occurred in those men who passed the stress test. Falk E, Shah PK, Fuster V Circulation 1995;92:657-671 demonstrated that 86% of heart attacks occur in vessels with less than 70% as the maximum obstruction. A vast majority of
patients with less than 70% vessel obstruction will pass their stress test.

Regarding [the] question of owning or referring for EBT imaging, I would be amused if it were not insulting. The mistake that is often made is that EBT imaging is a wildly profitable technology. It is not nearly as profitable as nuclear stress imaging. Indeed there are few EBT centers in the country that are as profitable as any random cardiologist's stress lab.

How can we justify not screening asymptomatic patients? Most heart attacks occur in patients with no prior symptoms and according to Steve Nissen, 150,000 Americans die each year from their first symptom of heart disease. My daughter is at this moment visiting with a friend who lost her father a few years ago to his first symptom of heart disease when she was 8 years old. That is not OK! We screen asymptomatic women for breast cancer risk. Women are 8 times more likely to die from heart disease than breast cancer. We do mass screening for colon cancer and we are over 10 times more likely to die from heart attacks than colon cancer. An EBT heart scan costs 1/8th the cost of a colonoscopy.

So what say we drop the sarcasm and look at this technology objectively. Read the literature, not just the editorial comments. This really does provide incredibly valuable information that saves lives.

Yes, a 90% reduction in heart attacks in my patients compared to the care I could provide 5 years ago when I was doing a lot of stress testing and referring for revascularization. Much better statistics than expected national or regional norms. I welcome your scrutiny.

That's probably the best, most concise summary of why heart scanning makes sense that I've ever heard. And it comes from a primary care physician in the trenches. With just a few paragraphs, Dr. Blanchet, in my view, handily trumps the arguments of my colleagues arguing to maintain the status quo of cholesterol testing, stress tests, and hospital procedures.

Note:
Dr. Blanchett talks openly about his affiliation with an imaging center in Boulder, Colorado, Front Range Preventive Imaging. I'm no stranger to the accusations Dr. Blanchet receives about trying to profit from the heart scan phenomenon. Ironically, heart scanning loses money. It is a preventive test, not a therapeutic, hospital-based procedure. Free-standing heart scan centers that do little else (perhaps virtual colonoscopies) usually manage to pay their bills but make little profit. Hospitals that offer heart scans usually do so as a "loss-leader," i.e., an inexpensive test that brings you in the door in the hopes that you will require more testing.

Accusations of profiteering off heart scans are, to those in the know, ridiculous and baseless. On the contrary, heart scans are both cost-saving and life-saving.

There's a fascinating and vigorous debate going on at the Heart.org website among Dr. Melissa Shirley-Walton, the recently publicized proponent of "a cath lab on every corner": Dr. William Blanchet, a physician in northern Colorado; and a Track Your Plaque Member who calls himself John Q. Public.

John Q. has been trying to educate the docs about the Track Your Plaque program. Unfortunately, Dr. Shirley-Walton essentially pooh-poohs his comments, preferring to lament her heavy work load. In her last post, when she discovered that John Q. was not a physician, she threatened to block his posts and delete all prior posts.

However, Dr. Blanchet has emerged as a champion of heart scanning, intensive lipid management, and lipoproteins, much similar to our program. In fact, many of Dr. Blanchet's comments were so similar to mine that John Q. asked me if it was really me! (It is definitely not.)

Here's a sampling of some of the discussion going on now:

Dr. Blanchett started out the discussion by saying:

Stent Insanity
I have no trouble agreeing with the argument that we have initiated the widespread use of DES without adequate study regarding outcomes. Shame on us.

That said, we are ingoring the DATA that shows that most heart attacks occur as a result of non-obstructing plaque and all the talk about which stent to use ignors the majority of individuals at risk. In addition, for a decade we have known that stenting does not improve net outcomes anyway.

What ever happened to effective primary prevention? We discarded EBT calcium imaging like moldy cabbage without even looking at the outcomes DATA. With direction provided by EBT calcium imaging and effective primary prevention, I have been able to reduce myocardial infarction by 90% in my very large Internal Medicine practice. Through effectively identifying patients at risk and measuring success or failure of treatment with serial EBT, I have made the argument as to which stent to use moot. No symptomatic angina and rare infracts equals little need for any stent.

Is anybody listening? Certainly not the cardiologists whose wealth and fortunes are based on nuclaer imaging, angiography and stenting.

Dr. Shirley-Walton, skeptical of Dr. Blanchet's claim of >90% reduction of heart attacks using a prevention program starting with a heart scan:

To rely soley upon a calcium score will deprive you of a lot of information that could be otherwise helpful in the management of your patients.

Without seeming sarcastic, I must refute : "of 6,000 patients I've seen 4 heart attacks in 3 years". Although I certainly hope your statistics are accurate, I will suggest the following:

You've not seen all of the heart attacks since up to 30% of all heart attacks are clinically silent. So unless you are echo'ing or nuclear testing all of these patients in close followup, you aren't certain of your stats.

Secondly, in order to attribute this success to your therapy, you would have to have nearly 100% compliance. In the general population, compliance is often less than 50% with any regimen in any given year of treatment. If you can tell us how you've achieved this level of compliance, we could all take a lesson.

Dr. Blanchett, commenting on his use of heart scanning as a primary care physician:

CAC [coronary artery calcium] is an inexpensive and low radiation exam to identify who is at increased risk for heart attacks.

A study of 222 non-diabetic patients admitted with their first MI found 75% of them did not qualify for cholesterol modifying therapy prior to their initial MI (JACC 2003:41 1475-9). In another study of 87,000 men with heart attacks, 62% had 0 or 1 major risk factors (Khot, et al. JAMA. 2003). Almost all individuals with 0 or 1 risk factor are Framingham "Low risk" and therefore will not qualify for cholesterol lowering therapies. (JAMA. 2001;285:2486-2497)

Risk factors alone are not sufficient. In my practice, of the last 4 patients who have died from heart attacks, none qualified for preventive therapies by NCEP guidelines.

Studies have shown that CAC by EBT provides an independent and incremental predictor of heart attack risk. (1. Kondos et al, Circulation 2003;107:2571-2176, 2. Am Heart J 141. 378-382, 2001, 3. St Francis Heart Study Journal of the American College of Cardiology July, 2005) The old saw that CAC simply reflects risk factors and age is just wrong.

Although CT angiography shows great promise to reduce unnecessary conventional angiography and is helpful in emergency room chest pain evaluation, I do not see CT angiography as a screening study in asymptomatic individuals. 10 times more radiation than EBT calcium imaging plus the risk of IV dye exposure makes CT angiography inconsistent with the principles of a screening test. Taken in the context of a primary care physician's evaluation of heart attack risk, EBT calcium imaging has great value.

Coronary calcium changes management by: 1. Identifying those at risk who do not show up with standard risk stratification (St Francis Heart Study: Journal of the American College of Cardiology July, 2005). 2. Motivating patients to be compliant with therapies (Atherosclerosis 2006; 185:394-399). 3. By measuring serial calcium, we can see who is and who is not responding to our initial treatment so that we can further refine our therapeutic goals (Atherosclerosis, 2004;24:1272).

When used in the primary care preventive setting, CAC imaging is indeed of great incremental value. In my practice, in improves my outcomes so greatly that it compels Melissa Walton-Shirley to question my veracity.

Dr. Melissa Walton-Shirley:

Ahhhhhh.......the aroma of profit making, I thought I smelled it. [Accusing Dr. Blanchett of referring patients for heart scans for personal profit.]

I will tell you that I was a little hurt when I was called "a typical cardiologist with a butcher block mentality" after my primary pci piece for med-gen Med was reviewed by the track your placque [sic] folks.

Though, it's clear that they misunderstood and thought I was cathing for dollars, instead my intention was to "push" for primary PCI for AMI, it left me seething until the blessing of a busy schedule and a forgetful post menopausal brain took its toll.
None the less, an honest open discussion is always welcome here but I would appreciate it if everyone would just divulge their affiliations up front so that the context of their opinions could be better understood.

I also insist that the compliance described by you William B. is rather astounding and a bit unbelieveable, however if it's accurate, you are to be congratulated.

Dr. Blanchett, in response to Dr. Shirley-Walton's statement that she relies on stress testing:

I think that the threshold of comfort you get from stress test stratification is different than what I consider acceptable. It is hard for me to tell a bereaved spouse that the departed did everything I suggested and still died from a MI. Coronary calcium imaging provides me the tool that I need.

Are you aware that there are a number of studies that show a dramatic increase in risk of MI in individuals with an annualized increase in calcified plaque burden of >14%? I consider this to be a valuable measure of inadequacy of medical management. A stress test does not become positive until we have catastrophically failed in medical management. Consequently, even in the patient with “high risk” stratification, one can justify a calcium score to establish a baseline to measure adequacy of primary prevention. Calcium scores by EBT cost about 1/5th the cost of a nuclear stress test and subject the patient to 1/10th the radiation of nuclear imaging and provides more precise information.

Regarding John Q, I do not think that non-medical prospective should be excluded from this blog. I think we as physicians benefit from hearing how the non-physician public views medicine. I have become much better at what I do by listening to my patients and learning from them.

Dr. Blanchett continues:

I had a heart attack--and I don't know why!

25. October 2006 William Davis (0)

Kevin came to my office for another opinion.

A husband and father of two teenagers, Kevin had his first heart attack at age 39. Kevin received two stents to his right coronary artery. The entire process took place in a flurry with little explanation over 48 hours, start to finish.

He smoked a pack of cigarettes a day, but the only history of heart disease in his family was his father, who, also a smoker, had his heart disease uncovered in his late 70s.

His internist subsequently prescribed Zocor even though Kevin's LDL cholesterol was a relatively unimpressive 128 mg/dl.

Kevin subsequently asked his cardiologist, "Where did I get the heart disease from?"

"Cigarettes. And genetics. You can quit the first. There's nothing you can do about the second." End of explanation.

This left Kevin frightened and demoralized. If much of the cause of his heart disease couldn't be identified, why bother quitting smoking? Why not enjoy what time he had left?

Kevin was understandably shocked when I told him that genetic causes were 1)identifiable, 2)quantifiable, and 3) correctable.

Kevin's full lipoprotein analysis subsequently showed the most dire combination that commonly accounts for coronary disease in young people: Lp(a) with small LDL particles. This, along with smoking, fully accounted for this young father of two's heart disease.

Along with starting Kevin on a new program for correction of his patterns, I also persuaded him to get a heart scan. What usefulness is a heart scan after the fact? Plenty. Even though Kevin's right coronary was no longer "scorable" because the steel in the stent obscured our measurements, the two remaining unstented arteries would still yield a score. This provides a baseline for future comparison. Even after a stent, Kevin could "track his plaque".

Butter basics

24. October 2006 William Davis (3)

There’s lot of confusion about butter, margarines, and their substitutes. Butter/margarine substitutes that avoid the negative aspects and provide modest health benefits are available, but I find that people confuse what's what. So here’s a brief primer.

Butter--Avoid it. Plain and simple. Butter is a rich source of saturated fat. Of 11.5 grams total fat per tablespoon, 7.3 grams are saturated. It is not better than margarine, contrary to simple-minded reports from some media sources. Butter raises LDL cholesterol, raises blood pressure, and has been related to various cancers.

Margarine--Not better than butter, arguably worse. Some argue that the trans-fatty acids, or hydrogenated oils, used to solidify vegetable oils to make margarine solid are worse than butter. In addition to the ill-effects of butter, margarine reduces HDL and raises cancer risk, perhaps even more than saturated fats. Hydrogenation yields a very unnatural structure that modifies cellular behavior of the sort that may promote the appearance of cancer cells. More recently, however, some of the major manufacturers, like Blue Bonnet, have produced soft spread products without hydrogenation. These are reasonable substitutes when used sparingly.

Smart Balance--This is a product made with canola oil, a source of monounsaturates (the best oil source after omega-3s), but manufactured without hydrogenation and therefore has no trans-fats. It does have, in my view, a bit too much saturated fat (1.5 gm per tbsp. in the 37% Light Spread; 2.5 gm per tbsp in the 67% regular spread). This is a reasonable product to use in small quantities.

There is also a Smart Balance Omega PLUS product that contains added flaxseed oil and sterol esters. I do not recommend this product because of the sterol content (see below). I also object to the manufacturers who label their products “rich in omega-3s” when they mean linolenic acid (in flaxseed), which is converted to a trivial quantity of omega-3s. Linolenic acid may pose unique benefits of its own, but it should not be listed as an omega-3 source.

Benecol--This is a butter substitute that contains stanol esters, a substance that reduces total and LDL cholesterol. Two tablespoons a day reduces LDL around 20 mg/dl, more or less depending on your starting cholesterol.

There’s a light and regular spread. The light contains 20 calories less per tablespoon but somewhat less monounsaturates, but the same LDL-reducing stanol esters. The manufacturer does hydrogenate the oils, yielding 0.5 mg trans-fats per tablespoon--a small drawback.

Take Control--Similar to Benecol, but made with sterol esters. Take Control also reduces LDL cholesterol. However, data from several high-quality studies from Finland suggest that sterol esters may, in some people, be absorbed into the blood. This is potentially concerning. There is a rare disease called sitosterolemia that results in coronary disease in teenagers and young adults in their 20s from increased absorption of sterol esters. While you can’t acquire this genetic disease, some people have the capacity to absorb sterol esters from their intestines very efficiently. I find it very disturbing and I suggest that you stay away this product and other sterol-containing products like HeartWise orange juice and Smart Balance Omega PLUS until the issue is clarified and safety assured.

Brummel and Brown--A blend of vegetable oils (soybean and partially hydrogenated soybean) with calories and fats reduced by blending in yogurt. This is an okay product. The hydrogenation yields trans-fats below the FDA required declaration limit of 1.0 mg.

There’s also 1.0 mg each of saturated and monounsaturated fats. The calories are relatively low as a consequence of the added yogurt, only 45 calories per tablespoon. This makes the Brummel and Brown a reasonable choice.

Other products are making their way out to supermarkets. Look for the type of oil used. Canola, olive, and flaxseed are the best. Also look for trans-fats and saturated fat content; both should be low, preferably <1.0 mg per tablespoon, ideally none.

The best choice among the above products in my view is Benecol, though it’s also the most expensive. It will yield substantial drops in LDL cholesterol. All the products in our informal tastings taste a lot like butter, or at least as well as we can remember what butter tasted like! The key with all of these products is use in moderation, since they all provide between 45?80 calories per tablespoon.

Let Dr. Friedewald rest in peace

24. October 2006 William Davis (1)

In the 1960s, doctors struggled with the concept of cholesterol and its relationship to heart disease. It was becoming clear that higher levels of cholesterol were predictive of heart disease. It was also becoming clear that the low-density fraction of cholesterol, or LDL, was somewhat better than total cholesterol in predicting heart attack.

Cholesterol was easily measurable in the 1960s. LDL was not. So, Dr. Friedewald, a noted lipid researcher at the National Institutes of Health, proposed an easy method to calculate LDL cholesterol from total choleseterol, HDL, and triglycerides:

LDL cholesterol = Total cholesterol – HDL cholesterol – triglycerides/5

This simple manipulation would put LDL cholesterols into the hands of the practicing physician and the American public. Dr. Friedewald recognized that this calculation only represented an approximation of LDL cholesterol and that it was thrown off, sometimes substantially, by any abnormal rise in triglycerides or reduction in HDL. But it served its purpose at an age when most doctors hadn’t even heard of cholesterol and the public was still sold on whole milk and “farm-fresh” butter, and Chesterfields were the cigarette choice of most doctors.

The world has since changed. Most doctors have heard about cholesterol and, along with the public, have been drowned in drug company marketing for cholesterol-reducing drugs. Most people with some level of common sense and health awareness no longer use butter or whole milk, and no longer believe that the brand of cigarette you choose can be healthy. But we’re still using Dr. Friedewald’s original calculation for LDL cholesterol. When you get an LDL cholesterol from your clinic, doctor, or hospital, >99% of the time it is obtained using Dr. Friedewald’s calculation.

Is it because there’s nothing better available? No, it’s not. There’s two reasons why your neighborhood primary care physician or cardiologist is still using this dinosaur of testing called LDL:

1) The lag in science to practice is 20 years. Accept that most primary care doctors are 20 years behind the times on many issues, LDL cholesterol included.

2) Insurance companies vigorously discourage testing beyond conventional lipids. The array of objections we get from insurance companies is mind-boggling. It would be funny if human life and finances weren’t at stake. These “new” tests are “experimental”, “unproven”, not endorsed by standard guidelines, not approved by some internal committee, or simply “We don’t know what this test is” ?we’ve heard them all.

What are the tests that are superior to Dr. Friendewald’s calculated LDL? There are several, listed here in order of best to worst:

1) LDL particle number--the value generated by NMR lipoprotein testing. This is the gold standard, most reliable test available, and the one I recommend.

2) Apoprotein B--More widely available even from conventional laboratories in hospitals. Not as accurate as NMR LDL particle number, but a pretty good choice. Apo B is the principal protein in LDL, VLDL, and IDL particles, and so it’s a better reflector of risk from all of these lipoprotein fractions, not just LDL.

3) “Direct” LDL--This is LDL that is actually measured. Unfortunately, it ignores the issues of LDL size and has some other pitfalls, but it’s still better than calculated LDL

4) Non-HDL cholesterol--So-called because it incorporates all undesirable cholesterol-containing lipids except good HDL, thus “non-HDL”. This is another calculation, though better than LDL (because it sums up the risk from other apoprotein B-containing lipoproteins). Non-HDL is calculated from Total cholesterol – HDL. It’s therefore available from any standard lipid panel. It’s little used in everyday practice, however, because most people and their physicians find it confusing.

5) Friedewald calculated LDL--You can see that calculated LDL is last on a list of choices. Yet this is the measure that doctors use day in, day out. It’s the measure that drug companies base billions of dollars of revenue and profits on.

It’s an everyday occurrence in my office that calculated LDL is 89 mg/dl, but the real value is somewhere between 160 and 200 mg/dl. That’s a big difference. Imagine your realtor tells you your house’s estimated value is $200,000 and that’s what you sell it for to an eager buyer. After closing, you find out your house was really worth $300,000. You’d be upset. But that’s what you’re often getting with LDL cholesterol?a bum deal.

It’s part of the reason people will say, “My doctor said my cholesterol was fine and that no cause for my heart disease can be found. He said it was genetic.” In reality, they could have sky-high LDL cholesterol revealed by LDL particle number or apoprotein B.

Use LDL cholesterol in a pinch when you’ve got nothing else. It’s also helpful to gauge any treatment effect of diet, functional foods, drugs, etc. But it is a seriously flawed tool to diagnose your initial level of risk.

The key to losing weight

23. October 2006 William Davis (0)

I saw three people this past week, all of whom set off on an effort to lose substantial quantities of weight. And all seriously needed to.

All three started with at least 70 lbs. excess weight; all showed substantial weight-sensitive lipoprotein patterns like low HDL, small LDL, high triglycerides, VLDL, and pre-diabetic levels of blood sugar. They also all shared high blood pressure.

All three also had high heart scan scores. Kate’s score was just over 1200. Tom, a 58-year old real estate developer, had a score of nearly 600. Susan, the youngest of the three at 52, had a heart scan score of 377¾99th percentile at this age. Losing weight was an absolute requirement for their plaque control program. Because their lipoprotein abnormalities and pre-diabetic patterns were triggered by weight, weight loss would provide powerful correction. Each and every one of them would need to lose much of their excess weight¾at least 50 lbs¾if they hoped to halt the relentless progression of their heart scan scores.

All three of them returned after 6-8 weeks, and all had lost between 17-24 lbs: spectacular results.

There’s no secret to weight loss. Each of them achieved their weight loss in slightly different ways. But they also shared several critical ingredients in their weight-loss efforts:

1) All three dramatically slashed their intake of wheat flour-containing foods and other processed carbohydrates and did so consistently. All also avoided the usual high-fat, high caloric-density foods like butter, margarine, fried foods, greasy foods, nuts roasted in oil, etc. They concentrated on vegetables, salads, raw nuts, lean proteins (inc. turkey, chicken, fish, lean red meats, low-fat cottage cheese and yogurt).

2) They stopped using food as a reward or as a consolation tool.

3) Exercise for one hour a day at least 5 days a week. The exercise in 2 of 3 of these people was just walking. It wasn’t strenuous, it wasn’t expensive. The women both liked walking with friends or their spouse. Tom followed a more common male path of more strenuous work on his treadmill, elliptical, and biking at the fitness club. But they all did it religiously and missed rare sessions.

4) They refrained from any and all alcoholic beverages. Yes, there are some advantages to 1-2 glasses of wine per day, but it stalls weight loss efforts.

5) They didn’t allow themselves any major indiscretions. There were no binges, major pig-outs at weddings, barbecues, or all-you-can-eat buffets. They did allow themselves an occasional “treat” but did so in small portions.

That’s it. But for most people, that’s simply too much. Adhering to an effort to lose dramatic weight requires day-after-day consistency. Nobody can lose the equivalent of 70,000 calories (20 lbs.) just by skipping a meal, a 20-minute walk, skipping the mashed potatoes at dinner.

It can be done. You’ve just got to be consistent about it.

How can I get my lipoproteins tested?

20. October 2006 William Davis (0)

This question came up on our recent online chat session and comes up frequently in phone calls and e-mails.

If lipoprotein testing is the best way to uncover hidden causes of coronary heart disease, but your doctor is unable, unknowledgeable, or unwilling to help you, then what can you do?

There are several options:

1) Get the names of physicians who will obtain and interpret the test for you. Go to the websites for the three labs that actually perform the lipoprotein tests: www.liposcience.com (NMR); www.berkeleyheartlab.com (electropheresis or GGE); www.atherotech.com (VAP or centrifugation). None of them will provide you with the names of actual physicians. They will provide you with the name of a local representative who will know who the doctors in your area who are well-acquainted with their technology. I prefer this route to just having a representative identify a laboratory in your area where the blood sample can be drawn, because you will still need a physician to interpret the results¾this is crucial. The test is of no use to you unless someone interprets it intelligently and understands the range of treatment possibilities available. Don’t be persuaded by your doctor if he/she agrees to have the blood drawn but has never seen the test before. This will be a waste of your time. That’s like hoping the kid next door can fix your car just because he says he fixed his Mom’s car once. Interpretation of lipoproteins takes time, education, and experience.
2) Seek out a lipidologist. Lipidologists are the new breed of physician who has sought out additional training and certification in lipid and lipoprotein disorders. Sometimes they’re listed in the yellow pages, or you can search online in your area.
3) Contact us. I frankly don’t like doing this because I feel that I can only provide limited information through this method. I provide a written discussion of the implications and choices for treatment with the caveat to discuss them with your doctor, since I can’t provide medical advice without a formal medical relationship. We also charge $75 for the interpretation. But it’s a lot better than nothing.
4) Make do with basic testing. Basic lipids along with a lipoprotein(a), C-reactive protein, fibrinogen, and homocysteine would provide a reasonable facsimile of lipoprotein testing. You’ll still lack small LDL and postprandial (after-eating) information, but you can still do reasonably well if you try to achieve the Track Your Plaque targets of 60-60-60.

In 20 years, this will be a lot easier. But for now, you can still obtain reasonably good results choosing one of the above alternatives.

What do you think about those heart scans?

20. October 2006 William Davis (1)

52-year old Jerry came in for a stress test. He displayed the usual apprehension: fidgeting while he sat on the bed, examining his surroundings, asking lots of questions.

“Your doctor asked you have have a stress test?” I asked.

“All the males in my family have had heart attacks by age 56, so my doctor suggested I have a stress test,” Jerry explained.

Jerry went on to tell me that he had exercised vigorously this morning for 45 minutes without symptoms. He had, in fact, gone surfing just several weeks earlier and described how aerobically challenging it was keeping up with the 20 year olds. “But I did it!” he proudly declared.

As he neared the end of his brisk walk on the treadmill, Jerry asked, “What do you think about those heart scans?”

Jerry had asked his primary care physician the same question. His doctor had apparently told him that they were just a gimmick. “We’ll get you a real test.”

Of course, Jerry’s stress test proved entirely normal. The likelihood of an abnormal stress test with his history of vigorous exercise was <2%. I explained to Jerry that not getting heart scan would be a mistake. In fact, a heart scan was the only easily obtainable test that would uncover hidden heart disease. In truth, the stress test was a waste of time—and an unneeded exposure to radiation.

If Jerry’s heart scan score turned out to be zero, great! He was probably spared the genes from the other males in his family, and his risk of heart attack in the next decade was nearly zero.

If his heart scan turned out be 1000, then an urgent scramble to uncover the causes and correct them to create a truly effective prevention program would be crucial for his long term health. Or, perhaps his score lies somewhere in between, but Jerry would then know how far along he stood on his way to heart disease.

Don’t be a victim of the ignorance of your doctor. Despite all the attention heart scans have received, the majority of doctors remain miserably, inexcusably in the dark. I say inexcusable because CT heart scans can uncover the number one killer of Americans, the number one cause of all deaths in any primary care physician’s practices, and it’s laughably easy. How can a physician not advise patients on the value of heart scans?

If given a choice and you’re without symptoms, a heart scan is far and away the superior test.

Olive oil for gourmets

19. October 2006 William Davis (0)

"The finest extra-virgin olive oils should not be used as a medium for hot cooking, but rather as a condiment or a finisher on top of your favorite savory foods. They are expensive, but if stored properly they will last for up to a year..."

You all know that olive oil is among the preferred oils to use: rich in monounsaturates, low in saturates, high in polyphenols.

For a fascinating perspective for the olive oil gourmet, go to www.npr.org, the website for National Public Radio. (Scroll down to the article or enter olive oil into their site search.) Their article, "Like fine wines, fine olive oils boast subtle joys" provides an insightful discussion on squeezing maximum enjoyment out of this wonderful "functional food".

As we emerge from the mis-directed low-fat craze of the past 20 years, we're re-discovering the joys of healthy oils. You'll find some great thoughts here

Vitamin D must be oil-based

18. October 2006 William Davis (10)

As part of the Track Your Plaque coronary plaque reversal program, we advocate vitamin D supplementation. Vitamin D has been shown to reduce blood sugar and reduce pre-diabetic tendencies, reduce blood pressure (it's a renin antagonist, a blood pressure hormone), it's far more important for bone health than calcium, and it may help prevent colon cancer, prostate cancer, and multiple sclerosis.

And, oh yes, it may facilitate coronary plaque regression.

One lesson I've learned is that vitamin D MUST be taken as a oil-based capsule or gelcap. You'll recognize it as a transparent or translucent, sometimes opaque, capsule. The list of ingredients may say something like "cholecalciferol [vitamin D] in a base of soybean oil", indicating that the active ingredient is oil-based.

Oil-based vitamin D3 skyrockets blood levels of 25-OH-vitamin D3 in to the normal range reliably and easily.

Tablets are a different story. These are generally white powdery tablets. The rise in blood levels of vitamin D3 are minimal, sometimes none. Women will often say "I get vitamin D with my calcium tablets."

People taking this form almost always have blood levels of vitamin D that are low, as if they were taking nothing.
If you're going to take vitamin D, the oil-based tablets are the way to go. They're not necessarily any more expensive. We've had good experiences with the Nature's Life 2000 unit capsule, as well as preparations from Life Extension. We have had negative experiences with the preparations from GNC, Sam's Club, and Walgreen's, all tablets and non-oil-based.

When is LDL cholesterol NOT LDL cholesterol?

18. October 2006 William Davis (0)

Darlene had a high LDL cholesterol, at times as high as 200 mg/dl. Her primary care doctor first tried Mevacor, then Pravachol, then Zocor, then Lipitor. Every statin drug failed to reduce Darlene's LDL below 160 mg/dl, even when maximum doses were used. The higher doses also resulted in nearly intolerable muscle aches and weakness.

When we sent Darlene's blood sample off for lipoprotein analysis, a surprise came back: she had a high lipoprotein(a), or Lp(a). This explained a lot.

LDL cholesterol is not always just LDL cholesterol. One of the particles that can masquerade as LDL is Lp(a). Darlene's story is typical of many people who've had high cholesterol levels poorly responsive to the statin drugs. That's because their LDL conceals Lp(a), which does not respond to these agents. LDL cholesterol does drop some because there's also some real LDL mixed in.

A poor response to statin agents or to nutritional strategies to reduce LDL is a tip-off that Lp(a) may be hidden. The answer: just measure Lp(a)! If you and your doctor don't measure it, you won't know whether or not you have it. Rather than a statin drug, we put Darlen on niacin. Not only did her Lp(a) drop, but her LDL also plummeted.
