NY Times Jane Brody misses the mark



NY Times' health columnist, Jane Brody, recently wrote a bit of fluff for her paper:

"CT Scans of the Heart Come With Trade-Offs


In her report, she says:

Coronary CT scans are being sold directly to the public, and they have found a market in health-conscious people who can afford them. But screening exams can have downsides. They can cause needless worry, and they sometimes reveal other potential conditions that require invasive procedures like biopsies to diagnose.

I soon learned that among the strongest proponents of CT scans of coronary arteries were physicians with financial ties to drug companies that make statins and others connected to imaging centers that would profit directly from widespread CT screenings.



She then goes on to discuss how the Framingham scoring calculation can tell you whether or not you are at low-, intermediate-, or high-risk for heart disease. She therefore concludes that heart scans are therefore irrelevant for the majority of people. She then proceeds to take a statin agent.

This sort of nonsense continues to get published, despite the clear lack of real "digging" for the truth. She clearly fell for the conventional arguments that continue to mis-guide the majority of people, myths like:

--the Framingham scoring system is reliable--Reliable it is NOT; it is susceptible to substantial "misclassification" bias, meaning people who appear low risk can actually be high risk, and people at high risk can actually be low risk. Among the latest studies that question the scoring system is Family history of premature coronary heart disease and coronary artery calcification: Multi-Ethnic Study of Atherosclerosis (MESA). This study pointed out how the Framingham scoring system, which leaves out family history, can cause people classified as low risk to actually have substantial heart scan scores. This is crucial. A heart scan gets beyond the uncertainties and shows with >95% certainty whether or not hidden coronary atherosclerotic plaque is present.

--"Coronary risk" is a dynammic phenomenon, subject to changes in a person's life. What if, for instance, a person smoked for 20 years, quit 10 years ago, lost 30 lbs, dropped their blood pressure as a result of the weight loss, then relied on the Framingham Risk Calculator to determine risk. They would likely be classified as low- risk, since risk factors now appear favorable. This person could easily have a heart scan score of 500, or 700, or 1000, levels that carry a cardiovascular event risk of 5-25% per year, hardly low-risk, because much of their risk accumulated earlier in life and is no longer revealed by an assessment of risk factors.

--There are sources of risk that have nothing to do with Framingham, such as lipoprotein(a), which is often revealed by family history; the presence of small LDL, which co-varies with HDL and triglycerides, but can behave independently also; and, my favorite, deficiency of vitamin D. This would explain part of the 60-70% of people who are typically mis-classified by Framingham.


Where did Ms. Brody get the idea that proponents of heart scans had ties to drug companies? I think she's barking up the wrong tree on that one. Of course, she ends up on a statin drug. For my part, I am a critic of statin drugs. Yes, they play a role, but they are miserably misused and abused by practicing physicians, based on the endless onslaught of drug company-sponsored trials that have served to distort their usefulness.

If I were Ms. Brody, I would be quaking in my shoes, not knowing what my true risk for heart disease was, relying on the--at best--30% reduction in heart attack risk of Lipitor or other statin drug. Ms. Brody: You are not cured, you're simply wearing a superficial Band-Aid. If you want to know your true risk for heart attack, and you want a precise value that you can track over time, the answer is simple: Reject the conventional notion and get a heart scan.

"There must be a mistake"

Neal is our current male record holder for greatest reduction in heart scan score. (Yes, the ladies have the lead!)

You may remember that this 40-year old man reduced his heart scan score from 339 to 161--a 51% drop. If you haven't yet read his story, go to

http://www.cureality.com/library/fl_07-001nealt51.asp


Neal reminded me of the experience he had when he underwent his second heart scan. Both scans had been performed at the same scanning center. At this center, the radiologists provide the added service of sitting down with people and actually going over the images and results.

After the scan, the radiologist pulled up the result from Neal's first scan for comparison. "There must be a mistake! This score is lower. Scores never drop."

The radiologist was apparently stumped, unable to provide an explanation. However, Neal then proceeded to tell the radiologist that we had warned Neal that this could happen and that he might even be told that it was due to error of some sort. This yielded a puzzled look on the radiologist but no further comment.

Of course it's not a mistake. It's something we achieve on purpose. Curiously, I still get comments that this is impossible, heart scan scores never drop, etc. Of course, those of you following this conversation know this is completely untrue. Heart scan scores DO drop, and sometimes drop enormous amounts, as it did for Neal.

I would have liked the radiologist to have had the lightbulb of understanding go off in his head when he realized that a reduction in heart scan score is a cause for celebration. Unfortunately, this radiologist's reaction is all too common: disbelief, confusion, dismissal.

Heart disease reversal is simply not in the realm of understanding of most doctors, radiologists and cardiologists alike. By conventional thought, if you have it, it just gets worse. "Maybe some high-dose Lipitor might help."

Ironically, when they see it right in front of their eyes, plain as day on the computer screen, they don't understand what has happened. It's Greek to them.

Should this happen to you, don't be surprised. Just bite your tongue, because you know better.

Jimmy Moore Interview: Is saturated fat the villain we thought?

Enter "weight loss" or "low carb" in your web search and you can't help but stumble across the prolific and widely-connected Jimmy Moore.

On his Blog, Livin' la Vida Lo Carb , Jimmy conducts a wide-ranging and informative discussion of the benefits of a low carbohydrate diet, a la Atkins. Though his initial claim to fame was the 180 lbs he lost in his first year of dieting on this approach, Jimmy has extended the conversation and built a considerable community of like-minded individuals, all of whom are participating in this grand "experiment."

Anybody who looks at lipoproteins and associated factors in health will quickly come to the conclusion that processed carbohydrates are the culprits in much of heart disease, diabetes, and heart disease. But I have had a hard time dismissing the ill-effects of saturated fat. After all, we've all been taught--drilled--with the idea that saturated fats cause LDL cholesterol to go higher, cause arterial constriction, growth of atherosclerotic plaque, inflammation, even cancer.

But there does indeed seem to be a growing sentinment that this long-held dogma may not be true. So I went to the ever-entertaining and informative Jimmy Moore, an able spokesman for these concepts.




TYP: It's certainly impossible to argue with the success you had in weight loss and the health you've regained on your program.

I think that the approach we use in diet in the Track Your Plaque program and the nutrition approach you advocate overlap to a great extent. We both emphasize plenty of vegetables, fruits, healthy oils, nuts, etc. The major point of difference seems to lie in saturated fat: We say restrict it, you say don't restrict it. Could you elaborate?





JM: Thank you for inviting me to your blog today, Dr. Davis. I have nothing but deep respect and admiration for the work you are doing to help educate others about how to keep their heart health in tip-top shape. Keep fighting the good fight, my friend.

While we do agree on probably 99% of the basic tenets of what I describe as
"livin' la vida low-carb," the issue of saturated fat to me is one where we
indeed do not. It's not a deal breaker regarding my support for what you do
just as I'm sure you would say the same regarding your backing of what I do. If
we all agreed on everything, then what a boring world this would be!

My thinking on saturated fat has evolved since I started eating this way nearly
four years ago. Like most people, I was terrified to eat ANY fat at all because
of the abject fear that people like Dr. Dean Ornish and other so-called health
"experts" instilled in me about how dangerously unhealthy it is to consume it.
This fat phobia is arguably the single biggest contributor to the ongoing
obesity crisis our world faces today.

With that said, you and I both know fat consumption is a part of a healthy
lifestyle. There are just too many benefits to the body that come from the
consumption of fats and even saturated fats such as coconut oil, butter, lard,
nuts, seeds, and animal fat when it is combined with a restricted carbohydrate
intake.

An intriguing study was presented at a scientific conference in November 2006 by two highly-respected researchers--Dr. Stephen Phinney from the University of California at Davis and Dr. Jeff Volek from the University of Connecticut--who conducted a side-by-side comparison of the amount of saturated fat in the blood of people on a low-carb diet with those following those highly-touted low-fat diets. What they found was the low-carb study participants had "significantly less" saturated fat in their blood than the low-fatties did.

Here are the actual numbers from the study:

- LOW-FAT/HIGH-CARB DIETERS: lowered saturated fat by 24%
- LOW-CARB/HIGH-FAT DIETERS: lowered saturated fat by 57%
- Eating 3X the saturated fat cut the amount in the blood in half

In an interview I conducted at my blog with Dr. Volek last year (here's the
link: http://livinlavidalocarb.blogspot.com/2006/09/volek-high-carb-low-fat-diet-useless-to.html),
he said the conventional wisdom regarding fat, especially saturate fat, is dead
wrong while the significance of carbs is all but ignored by those who claim to
understand the metabolic response mechanism.

Here's what Dr. Volek said in my interview:

"Eating fat does not make you fat, storing fat makes you fat. And carbohydrates play a major role in storing fat. So the level of dietary carbohydrate is really the most important factor to control because it dictates what happens to fat. Carbs are dominant and fat is passive. When carbohydrates are low, fat tends to be burned, and when carbohydrates are high dietary fat tends to be stored. The same holds true for the atherogenic effects of saturated fat. The body handles saturated fat better when carbohydrates are low."

Long-time low-carb practitioner and current President of the American Society of Bariatric Physicians (ASBP) Dr. Mary C. Vernon from Lawrence, Kansas confirms the findings of Dr. Volek and Dr. Phinney in a succinct recap of what their research showed.

Here's what she said:

"Eating fat (whatever kind) does not make you fat. It does not increase blood
stream saturated fat. Eating carbs does make you fat. Eating carbs does put
saturated fat in your blood stream."

To me, as a simple layperson with no medical background, it's all a matter of who you believe. Do we continue to buy into the low-fat propaganda machine and assume that what they are telling us about saturated fat is true? Or do we instead start paying closer attention to the latest research that is coming out about saturated fat that doesn't exactly line up with the edicts of the last three decades? The choice for me is a simple one.

And if you haven't read the brand new Gary Taubes book entitled GOOD CALORIES, BAD CALORIES yet, then it is REQUIRED reading to arm yourself with the research studies about fat. After you read that book, it will be almost impossible for ANYONE to believe fat, including saturated fat, is unhealthy.



TYP: In our program, we advocate a wheat-free approach for many people, because of the addictive potential of wheat products, as well as the flagrant creation of the small LDL pattern that wheat products create, thereby adding to atherosclerotic plaque growth. However, many people express a concern over a lack of fiber in their diets if they eliminate whole wheat bread, pasta, Fiber One, Raisin Bran cereal, etc.

Have you encountered any phenomena of low-fiber on your approach?

JM: What an excellent question and I even wrote a humorous blog post about the importance of fiber intake called "Allow Your Bowel To Shake, Rattle, And Roll" (http://livinlavidalocarb.blogspot.com/2006/06/allow-your-bowel-to-shake-rattle-and.html).

Fiber consumption is another one of those issues that not everyone who advocates
a controlled-carb approach agrees is necessary. I'm on the side that it IS a healthy part of your diet and should be consumed in high enough quantities to keep you regular...something many people think is impossible on a low-carb diet.
Not true! I take a fiber supplement like FiberCon, eat plenty of high-fiber vegetables, drink lots of water, and even consume high-fiber, low-carb products that help me maintain high levels of fiber in my diet (see my favorite ones in this post: http://livinlavidalocarb.blogspot.com/2007/04/there-are-plenty-of-low-carb-fiber.html).

As for consuming the highly-touted "healthy whole grain" cereals that you
mentioned, what a travesty that would be for people trying to manage their
weight and health. While the cereal manufacturers have had a heyday in their
marketing efforts promoting their whole grain content, it's all just a big fat
ruse on the public trying to convince them that these cereals are somehow healthy for their bodies. Sure, they're better than the sugary cereals, but all those grains are metabolized as sugar inside the body, so you might as well be eating Lucky Charms and Fruit Loops!

Many of these "healthy" cereals contain as many carbohydrates in a single bowl
without the milk as I would eat in an entire day. Raisin Bran, for example, which used to be my favorite cereal before my low-carb lifestye, has a whopping 47 grams of carbohydrates. Needless to say, I don't touch that with a ten-foot pole nowadays because I would surely gain weight and get back on the blood sugar rollercoaster ride that I was on prior to beginning the Atkins diet on January 1, 2004. Plus, all those carbs just make you hungrier sooner, so it's better just to eat some delicious eggs cooked in butter, a couple of slices of sausage, and tomato slices to start your day off right. You'll get enough fiber in your body the rest of your day.



TYP: 180 lbs of weight loss in your first year is absolutely astounding.

I take it that you've continued this trend and have lost more weight since your early success. What role did exercise play during your first year and subsequently?
How are your food choices today different from that first year?

JM: Yes, that weight loss was indeed one of the greatest accomplishments I have ever experienced in my life. It was a hard-fought battle that even included a 10-week period where I was stalled with no weight loss. But I knew my chosen diet was the right one for me because I felt better than I ever had on a diet, was never hungry because I ate every 2-3 hours, and could see myself doing this for the rest of my life. So far, so good!

It has been close to four years since I began this journey and I am indeed continuing this pathway to better health. My low weight in 2004 was 230 pounds and I currently weigh 225 pounds. As long as I keep my carbs reduced, I am able to maintain my weight right where it is. I've had minor fluctuations in both directions where I got down to as low as 215 pounds at one point (but didn't feel good at that weight) and as high as 252 pounds (when I was allowing myself one too many high-carb foods here and there).

There's a balance that people need to find for themselves and it's different for
all of us. I am one of the unlucky people who has to keep his carbohydrate
intake below 50g daily or I gain. It's just a fact of life that I've come to
grips with and realize is a necessity in order to manage my weight for the rest
of my life. But I wouldn't have it any other way!

Exercise was indeed a part of my low-carb weight loss success in 2004 as I
forced myself to do cardio every single day as a commitment to this journey. In
hindsight, that was probably not the best thing for me to do since the body has
a rather peculiar way of telling you it needs to wiggle and move spontaneously
on its own rather than forcing the issue. But I consider the exercise I did to
be such an integral part of my success that I dedicated an entire chapter of my
book to the subject.

Today, my daily cardio routine is out the window and I choose instead to engage
in activities outside the gym that let me burn calories and have some fun in the
process. I regularly play volleyball, basketball, and referee flag football at
my church which all give me quite a workout. I'm very physically active and fit
on my 6'3" body and just enjoy burning off all this excess energy that I have
been given since losing nearly have my weight! I do want to get into a little
more organized resistance training routine soon to try to shape and tone some
areas of my body that still show signs of that 410-pound man I used to be
(although the loose, hanging skin in my abdomen and inner thighs isn't going to
get any better with exercise since the elasticity has been ruined from being
stretched out so far). Here is a link to some posts and pictures I have written
about this subject:
http://lowcarblinks.blogspot.com/2007/04/theme-based-low-carb-links-loose-skin.html

As for my food choices today compared to my weight loss year in 2004, they
haven't really changed a whole lot. This was a lifestyle change in every sense
of the phrase and I've learned to implement this way of eating into a permanent
and healthy diet that I can and will gladly live with forever and ever amen. I
probably eat more berries, melons, and nuts today than I did then, but otherwise
it's the identical diet.



TYP: I'm sure that you are as impressed as I am that much of the wisdom in healthy eating doesn't always come from doctors or clinical studies, but from the collective wisdom that emerges from this national experiment (inadvertent, for the most part) in eating. Your Livin' La Vida Low-Carb is, in my view, a perfect example of the sort of wisdom that is helping all of us understand what happened to our health over the last 20 years.

Does the approach you advocate today differ in any substantial way from the diet as originally articulated by Dr. Atkins?

JM: Actually, my personal diet is precisely based on the teaching of the late great Dr. Robert C. Atkins in his classic bestseller DR. ATKINS' NEW DIET REVOLUTION (DANDR) book. But most people are surprised when they learn I do not necessarily advocate the Atkins diet as the nutritional approach for everyone.

Nope, I sure don't!

Instead, my philosophy is simple: Find the diet plan that will work for YOU, read and research everything you can about that chosen plan, follow that plan exactly as prescribed by the author of that book, and then KEEP doing that plan for the rest of your life. If you do that, then there's no reason why you can't succeed just like I did.

Anyone interested in doing the low-carb lifestyle and needs help finding which
plan is right for them, let me HIGHLY encourage you to pick up a copy of Dr. Jonny Bowden's LIVING THE LOW-CARB LIFE (read my review: http://livinlavidalocarb.blogspot.com/2005/05/must-have-book-for-everybody-doing-low.html).
It's the perfect overview of low-carb living with a comparison and recap of the
major plans.

THANK YOU again for allowing me to share my story with you and your readers, Dr.
Davis!

TYP: And thanks to you, Jimmy!

Mammogram of the heart

Some people have called CT heart scans the "mammogram of the heart." The analogy contains a lot of wisdom.

First of all, both--mammograms and CT heart scans--are screening tests, one for cancer, of course, the other for coronary atherosclerotic plaque. Both are performed in specific age groups, mammograms in women 40 years and over (generally), heart scans in women 50 years and over (generally).


















Mammograms: Left, normal; right, a small mass. (Courtesy Nat'l Institutes of Health and Wikipedia.)



Both are also meant to be repeated periodically when normal as a surveillance process.

Both use low quantities of radiation of about 0.3-0.4 mSv (the most real-life measure of total body exposure), a modest quantity of radiation.

Both are good for their purposes, though not perfect. Can a mammogram performed properly miss a small cancerous mass? Sure it can, but it's still unusual. Can a CT heart scan miss the non-calcified plaque prone to rupture? Sure it can, but this is also unlikely (<5% probability).

Given the exorbitant costs of medical tests, both are quite inexpensive. On the flip side, they are both also quite unprofitable for the centers providing the tests. Unfortunately, this means that mammography centers and heart scan centers come and go because of the difficulties of the profit-side of these services.

Both tests initially struggled to gain acceptance among the medical community. In 1960, for instance, mammograms were performed on standard x-ray devices, the same as that used to perform chest x-rays--low precision, high radiation back then. In 1969, dedicated mammography devices made the scene. However, it took over 10 years for even these new dedicated devices to become widely used. Use of mammograms has gradually increased over the ensuing 20 years. In other words, 47 years have passed since the introduction of mammography.

CT heart scans, of course, have had a shorter history of approximately 20 years, since engineer, Dr. Douglas Boyd, first invented the "ultra-fast" EBT devices, the first devices with sufficient scanning speed to scan the heart and coronary arteries.

One interesting difference between the two: In a woman between the age of 50 and 60, the likelihood of detecting cancer is 1 in 237. The likelihood of detecting coronary atherosclerotic plaque? About 1 in 4. Coronary disease eventually kills 1 in 3 females, hugely overshadowing breast cancer in frequency.


Progress on both fronts, one in cancer detection, the other in atherosclerotic coronary plaque detection. But still lots more progress to go.

Dr. Susie Rockway on conjugated linoleic acid (CLA)

I’m fascinated by the perspectives that nutritionists (free-thinking ones, at least), food scientists, and biochemists bring on nutrition and nutritional supplements.

A few months ago, I met a fascinating nutritionist/biochemist named Susie Rockway, PhD. Dr. Rockway brings a world of experience in the world of nutritional supplements, clinical trials with supplements, and their development. She has special expertise in conjugated linoleic acid (CLA), having been among the scientists who initially developed CLA as a supplement. We are also exploring CLA as a possible addition to the Track Your Plaque program and wanted to get Dr. Rockway’s perspectives.

So I asked Dr. Rockway if she’d answer a few questions for us.






TYP: Dr. Rockway, we understand that you are particularly excited about the prospects of CLA for FAT loss and perhaps for regression of atherosclerosis. Can you tell us about the origins of your interest in CLA and why you're so enthusiastic?

Dr. Rockway: I have been fascinated with this unique fatty acid since the early 1990’s when CLA was first being discussed as nature’s most potent anti-carcinogen. I was then working in the granting/funding section of the National Dairy Council and saw this molecule as truly one of the future functional fats that would likely benefit people (next to omega-3’s!)

I think the benefits of CLA have just begun to be investigated—animal studies are extraordinary for showing fat reduction, lean mass (muscle) increases, immune enhancements, blood glucose normalization, anti-inflammatory properties and plaque reduction!

Human data to date is very encouraging for fat reduction. As a nutritionist seeing the massive increase in abdominal fat (stomach fat) in the world population and the direct relationship to cardiovascular disease, I see CLA as a great supplement to take to help this. Of course eating lots of vegetables, fruit, lean protein and whole grain products is also a must for maximizing good health.

I am studying the impact of CLA in reducing muscle loss in aging women—a condition known as sarcopenia. As we lose muscle with age, we lose strength, falls increase, we become frailer, and eventually many of us lose our independence. Along with the muscle atrophy, most people gain fat—never a good thing! So, if CLA can reduce fat and increase muscle, our bodies are more likely to withstand the hurdles that life throws at us much more efficiently.

So, how can you not be excited about this very bioactive molecule?




TYP: What are your specific areas of interest in nutrition and health?

Dr. Rockway: I strive to understand the role of bioactive molecules that can be taken to improve the aging process and enhance health.

As a trained nutritional biochemist, we tend to look at cell metabolism in a very ideal sense: what we learned in our biochemistry texts years ago where all substrates, proteins, enzymes, etc. are made exactly when we need them, where all cells behave as they should.

Unfortunately, little research has been devoted to understanding the changes in metabolism as we age. Do we still produce everything as efficiently as when we were 20? I suspect not. So, I think we need a little help, and supplements are a key to getting there.

Two nutrients that I think are emerging as “super nutrients” are the fatty acids found in fish oil (EPA and DHA) and vitamin D. Where we know these two nutrients are essential for life, we are seeing that they play a huge role in the QUALITY of life. Mood, depression, PMS, wound healing, bone growth, atherosclerosis, and arthritis are clinical areas where we see a direct benefit with doses of omega-3 and Vitamin D that are probably much greater than the RDA. Our current requirements for nutrients are really based on fixing deficiencies and not maximizing health, and maximizing health is where I’m at.

Thus, I am very interested molecules like CLA as mentioned above, and other bioactive ingredients such as plant derived ingredients (phytochemicals) called flavonoids that may well help explain why people who have diets high in fruits and vegetables are less likely to have certain cancers and heart disease. Reducing oxidative stress through foods that provide these active molecules (think colored fruits and veggies) is a new and exciting area of research.



TYP:The big "diet experiment" in America has clearly steered people in the wrong direction, usually by 50 or more pounds. As a scientist in nutrition, what are your thoughts?

Dr. Rockway: The American Heart Association was keen 20 years ago to promote the low-fat diet for all Americans as the key way to reduce cholesterol levels and decrease chance of heart disease, the number one killer of men and women. However, I must admit the nutritional community bought into this one, too. Unfortunately, the general public took this message to reduce percent fat in their diet (and they did a bit), but increased overall calories instead—and a large portion of the increased calories was from simple carbohydrates. I’m convinced that this in itself has been part of the huge rise in obesity…we simply eat more food and it’s not the healthy kind of food either.

When you increase sugar intake beyond what you burn off, you will store some of it as glycogen in the liver and muscles, but you will convert most of the excess into fat—and that we can store very efficiently! The fat that is made in the liver is sent to the blood as VLDL’s which are the precursor to the class of lipids called low density lipoproteins (LDL) that are the “lethal” type of cholesterol circulating in our blood.

So, Americans now have to listen to a new message that they need to eat more fruits and vegetables in hopes they will cut down on fast foods—tending to be high in fat (saturated particularly), low in fiber and low in nutrients and other high calorie dense foods. We nutritionists have our work cut out for us, that’s for sure.



TYP: We are especially excited that nutritionists are assuming a leading role in shining light on the confusion in diet and nutrition that has characterized the last 40 years. Do you have a sense for the emerging important issues for the next 10 years?

Dr. Rockway: Certainly, the scientists in the nutritional field are well aware of the problems facing this nation—it’s in fixing them that we fall short!

We aren’t very well coordinated to get a single message out, nor do we all agree on what that message should be. I feel that people need to eat healthy MOST OF THE TIME, exercise all of the time, and take supplements that have clear evidence of benefit. Lots of my colleagues would not concur with supplement use. Our bodies were designed to move a lot and eat a lot…we just do the latter now and are paying the price!

One emerging and very exciting area that we have to teach Americans is that all fat is not bad. The different types of fat—omega-6 vs. omega-3, are where we need to focus our education.

Decreasing the corn oil we pour on everything needs to go out the window! Consume olive oil and eat fish or take fish oil supplements—we simply have tons and tons of research showing the benefits of reducing the ratio of omega-6 to omega-3. Did you know that cattle that are grass fed actually have less omega-6 in their tissues and more CLA? But most cattle are fed corn-based diets, so we have perturbed their natural selection of food and their fat composition.

See, it all comes back to CLA!


TYP: Thanks, Susie!

Which is better?

If you have the common pattern of high LDL particle number (NMR) with small LDL--a pattern highly related to coronary plaque--which is better:




Lipitor or a combination of fish oil, vitamin D, and elimination of wheat?


Lipitor quite effectively reduces LDL particle number, usually on the order of 40% or so. Effect on LDL particle size: None. Side-effects: plenty, including muscle aches (inevitable in my experience, not the ridiculous 2% they claim) and occasionally mental effects such as impaired short-term memory.

Lipitor does seem to exert a modest effect on reduction of C-reactive protein, around 30%. It also reduces cardiovascular events by 30%.



A combination of fish oil, vitamin D, and elimination of wheat:

Reduces LDL particle number commonly by a similar 40% (though variable, depending on body weight). There is substantial improvement in LDL particle size, a large drop in C-reactive protein, often >50%, a 30% or more reduction in cardiovacular events.



On this combination, however, you also:

--Lose weight, often substantially.

--Improve bone health, esp. osteoporosis and arthritis.

--Reduce cancer risk from the vit D supplementation.

--Reduce risk of stroke.

--Reduce postprandial (after-eating) abnormalities like intermediate-density lipoprotein.

--Reduce winter blues.

--Experience more energy.

--Obtain increased clarity of thought (from elimination of wheat).

--Reduce blood pressure.


Oh, and there's no muscle aches.

Heart health for stupid people

I'm kidding.

What I'm referring to is the incredibly lame information I come across that passes as "heart health" on the internet, magazines, and other media. Just to keep abreast of what is being said, I subscribe to multiple newsletters and magazines and I witness the sorts of advice offered to the reading public.

A recent long-winded article on a popular website listed the "exciting" strategies available for a healthy heart:

Eat healthy--by eating a "balanced" diet low in saturated fat

Don't smoke

Exercise

Don't ignore chest pain symptoms or breathlessness

Know your numbers! meaning your cholesterol numbers. "If your cholesterol is high, you may need to speak to your doctor about medication to reduce it."


Surely they must all believe we're stupid. Otherwise, why would they repeat the same obvious information over and over again? Quit smoking? Gee, you think so?

How about some real heart healthy advice:

Get a heart scan--since we have to accept that cholesterol values are a miserable failure in detecting hidden heart disease. So is waiting for symptoms to appear.

If you have any measure of coronary plaque, ask your doctor to assess lipoproteins, not lipids (cholesterol).

Take fish oil for omega-3 fatty acids--At a dose of 1000 mg or more of EPA + DHA, heart attack risk is reduced by at least 28%.

Eliminate wheat and other processed carbohydrates --Small LDL has emerged as the number one cause of coronary plaque, not high cholesterol from saturated fat.

Get vitamin D assessed--The effects are huge--HUGE. There's already a study in a kidney disease population that showed a substantial reduction in mortality with vitamin D supplementation. More data are coming, including our own.


That's a start--truly effective, practical heart healthy strategies that go way beyond the conventional bland advice.

Money, money, money, money

I've been asked the question numerous times:

Why aren't heart scans more popular?

First, let me qualify by saying that heart scan have indeed grown in popularity over the past decade. I think the real question is:

Given the enormous usefulness of CT heart scanning to detect hidden, asymptomatic coronary atherosclerotic plaque, why haven't they more readily been incorporated into conventional medical practice?

That's easy: There's no money in it.


Say, for instance, your doctor orders a heart scan and somehow receives a $1000 for the test. Scan centers would be scanning 100 people a day, falling over themselves to do scans.

This would be similar to a heart catheterization. Order a catheterization, do 30 minutes of work, and get $1000. Or, order a nuclear stress test. Depending on how its done and where, $1800-4000 is paid by the insurer.

Order a CT heart scan and how much is paid to the doctor? Usually nothing. At most, a nominal fee might be paid if the doctor reads the scan.

With heart scans, there simply is no big payoff.

We learned the implications of this situation 10 years ago when I was trying to help my friend, Steve Burlingame, the owner of Milwaukee Heart Scan. (I am NOT and NEVER WAS an owner.) Steve was trying to let everybody know about this great new $2 million dollar heart scan device in the Milwaukee area.

The first few years were tough for Steve: Carrying the substantial expense of this device while doctors essentially gave the technology the cold shoulder. It simply did not fit into the financial equation. Why change the way things were, particularly when there was virtually no financial reason to do so? To counter this, Milwaukee Heart Scan followed the model many other scan centers have followed and marketed directly to the public.

I see this as yet another example of why people need to take control of health care away from doctors and hospitals, the current controllers of the system who are providing a disservice to the public they are supposed to be serving. These institutions, for the most part, serve their self-serving financial interests, not your health interests. It's the same equation that drives food manufacturers to make more and more processed carbohydrate foods that they sell for substantial markups, not green peppers and cucumbers that make little money.

I regard heart scans as among the greatest self-empowering tools in health ever conceived. It was that way in 1997; it remains that way in 2007.

The many faces of LDL

Ginnie came in for an opinion about her heart scan score of 393. At age 57, this put her in the 99th percentile, a high score.

As usual, we did a lipoprotein analysis by NMR (Liposcience). Some numbers:

LDL cholesterol: 96 mg/dl
This value puts Ginnie's LDL in the most favorable 25% in the country.


LDL particle number: 2140 nmol/l
This value is in the worst 25% of the country and is the equivalent of an LDL cholesterol of 214 mg/dl (take off the zero).

In addition, over 90% of Ginnie's LDL particles fell into the small class.

Had we run some other values, how would they have turned out? These are my estimates (since we didn't actually run them in Ginnie), but having run side-by-side numbers in past, reasonable estimates would have put:

Apoprotein B somewhere in the 120 to 140 mg/dl range

Direct LDL 100-130 mg/dl range.


In other words, conventional calculated LDL is the least reliable of all the ways of examining low-density lipoprotein.

It can also go the other way: High calculated LDL, low LDL particle number or ApoB or direct LDL. And, indeed, these other measures have proven superior in their ability to predict "events" like heart attack over conventional calculated LDL.

Unfortunately, relying on conventional LDL is like a broken speedometer on your car. You really can't gauge accurately how fast you're going; sometimes you could be way off. While insurance companies and many physicians still continue to balk at this argument, the data have already been generated that show that lipoprotein analysis (my bias is NMR) is not just superior, but enormously superior for accuracy and event prediction.

In addition, lipoprotein analysis has proven a crucial tool that accounts for our extraordinary success in reducing and controlling CT heart scan scores in the Track Your Plaque program. I doubt that we could have achieved the same level of success using conventional lipids.

I'm also aware of the logistical difficulties obtaining lipoprotein testing in a world enthusiastically supportive of hospital procedures and smugly ignorant of superior prevention tools like lipoprotein analysis. I've learned just how difficult it can be in our Track Your Plaque Member Forum; I've also learned about some strategies for obtaining these tests that I hadn't been aware of, thanks to the resourcefulness of our Members.

We will be working on some solutions in the coming months.

What does "Success" mean in the Track Your Plaque program?

Say you begin with a CT heart scan score of 400.

You correct your lipoprotein pattterns, take fish oil, correct 25-OH-vitamin D3 to 50 ng/ml, correct your other hidden patterns, follow a diet suited to your patterns.

One year later, you get another heart scan. What score would constitute "success"?

With all of our recent talk about record-setting reductions in heart scan scores, is it really necessary to drop your score that much to succeed?

For instance, is our latest record-setting 63% drop in score better than "only" a 10% drop in score? Both represent reversal of coronary plaque. Both signify huge reductions in risk for plaque rupture, or heart attack.

You can read about how we view the various forms of success in the program by reading our latest Track Your Plaque Special Report, Winning Your Personal War with Heart Disease: The Track Your Plaque 5 Stages of Success.

We are making the Report available to everyone. Just go to the www.cureality.com homepage.
Letter from the insurance company

Letter from the insurance company

Claudia got this letter from her health insurance company:

Dear Ms. ------,

Based on a recent review of your cholesterol panel of January 12, 2011, we feel that you should strongly consider speaking to your doctor about cholesterol treatment.

Reducing cholesterol values to healthy levels has been shown to reduce heart attack risk . . .


Okay. So the health insurer wants Claudia to take a cholesterol drug in the hopes that it will reduce their exposure to the costs for her future heart catheterization, angioplasty and stent, or bypass surgery. This is understandable, given the extraordinary costs of such hospital services, typically running from $40,000 for a several hour-long outpatient catheterization procedure, to as much as $200,000 for a several day long stay for coronary bypass surgery.

So what's the problem?

Here are Claudia's most recent lipid values:

LDL cholesterol 196 mg/dl
HDL 88 mg/dl
Triglycerides 37 mg/dl
Total cholesterol 291 mg/dl

By the criteria followed by her health insurer, both total and LDL cholesterol are much too high. Note, of course, that LDL cholesterol was a calculated value, not measured.

Here are Claudia's lipoproteins, drawn simultaneously with her lipids:

LDL particle number 898 nmol/L
Small LDL particle number less than 90 nmol/L (Values less than 90 are not reported by Liposcience)

LDL particle number is, by far and away, the best measure of LDL particles, an actual count of particles, rather than a guesstimate of LDL particles gauged by measuring cholesterol in the low-density fraction of lipoproteins (i.e., LDL cholesterol). It is also measured and is highly reproducible.

To convert LDL particle number in nmol/L to an LDL cholesterol-like value in mg/dl, divide by ten (or just drop the last digit).

Claudia's measured LDL is therefore 89 mg/dl--54% lower than the crude calculated LDL suggests.

This is because virtually all of Claudia's LDL particles are large, with little or no small. This situation throws off the crude assumptions built into the LDL calculation, making it appear that she has very high LDL cholesterol.

Do you think that Big Pharma advertises this phenomenon?

    Dr. Davis,

    I think total cholesterol should be 290, perhaps, and not 29?

    I have started using the lipoprofile in my practice.  Patients with relatively normal lipid profiles are startled with the results.  Getting them to make any changes is another thing, but I will keep trying.

    I live in the UK under the National Health Service but I also  have private medical insurance. I know that neither my private medical insurance company, nor the NHS itself, know my cholesterol numbers - they are known only to the lab, my doctors and me. How is it that patient information, which should be confidential, is given to insurance companies ? I find that a very worrisome aspect of this.

    I find it kind of strange how obsessed american doctors are with cholesterol levels, in my country (Iceland) this is not such a big deal.

    It's almost as if the doctors in America are going out of their way to find something wrong with their patient so that they can treat it.

    For example high cholesterol, thyroid disorders. I pretty much never hear people talk about those things here.

    Some insurance companies routinely require physical examinations before they will write life insurance and are happy to find any reason not to write the insurance. Could this have been a life insurance company?

    What do you think is the best line of defense for the patient? My husband has similar calculated LDL - 181, the rest of numbers are excellent and he is in a very good health at 50 years old. Blood pressure is excellent(115/65), pulse is 45 at rest, fasting BS is 76. Our doctor admits it, but recommends Lipitor anyway. Our health insurance is about to be changed and it makes me worry about perspective pressure from insurance people on my husband to take that Lipitor.

    How does an individual give honest answers on health questionaires when applying for new or additional life or health insurance?  If they ask my PCP they would be told that I am low risk for heart attack.   If they look at my CT scan score they would see that I am in the 90th percentile - high risk.
    These are hypothetical questions at this point but my inclination would be to base my answer on my PCP's opinion rather than my calcium score, in part because medical insurance does not cover CT scans (apparently because they don't consider them to be a reliable predictor of risk) and in part because I have taken steps to significantly reduce my risk.

    Let's name names!  I have coverage by United Health Care through an employer.  I have gotten several letters in the past couple of years telling me I NEED this test, or that that test, to maintain my good health!  [However, never anything about the value of lipoprofile testing!]

    I consider this an abhorrent practice, an invasion of my privacy, and totally reject their "advice".  Advice should be coming from my doctor, and in fact it is.  I don't need their nurse "case manager" nor this advocacy for excessive testing.

    There's nothing like a letter from an insurance company to raise blood pressure!

    It is very disturbing to me that 1) her health insurance has access to her medical records and 2) that a for-profit organization is getting involved in her healthcare. Having moved from Australia about five years ago, everything about American health care disturbs me. I trust no one; they all seem to be desiring a profit and therefore paperwork is their main concern, not patient care, health, or longevity.

    My last test showed calculate LDL at 208, however the one from three months ago was "directly measured lipid" and showed 263 LDL direct, so might the calculated version be wrong in either direction?  I have pattern A and am FH.

    I'm for naming names too!  I have Aetna health insurance through my employer. I don't get letters from them, but I get emails. Just today, I told my email program to automatically delete any further emails from the "Simple Steps to a Healthier Life" program. Plus whenever I sign into the online portal, I get nagged to have all kinds of tests, fill out questionnaires, and join health improvement programs.  I got so tired of the demand that I "fill out a health assessment questionnaire" I finally gave in, hoping it would be removed from the page. It just opened a new can of worms: now I have a half dozen new "suggestions" on my "to do list". Bah humbug!

    I'm of the "live and let live" school.  Why go looking for trouble?  As long as I'm not having symptoms, I feel no need to undergo all of these tests.

    Thank God my doctor is beginning to understand that I'm not going to be taking any of those Pharma-pushed poisons just because my lab results don't meet someone's criteria. Once again, I say Bah humbug!

    Ah, United. I have Oxford/United. '
    Several years ago, when everyone at Oxford (and patients) worked toward a noble goal of "salary" for their CEO of 1.6 Billion a year, they sent me several letters suggesting that I have basic check up. I followed their suggestion. Then, I started to receive letters ... refusing to pay - 100% refusal. Each time, I had to call and ask nicely and politely: "Are you nuts?" They paid.

    Though I am not in the habit of defending health insurers, I have found that they tend to provide a benign "you should speak to your doctor about . . ." kind of approach.

    I often wonder, however, if at some point they start to be more coercive. Something like: "You should strongly consider a cholesterol-reducing drug. We anticipate that your premiums may be higher if you do not."

    That would be scary.

    Ah, I should have continued.
    In a way, Oxford achieved their goal. What they paid was minimal, but they avoided bigger cost at that time.
    They scared me to death - if they don't pay for what they send to ( with letters firmly printed) which is basic, stated officially in some book as my right, they probably won't pay for anything else. I neglected all symptoms and asked for medical attention when I really didn't have any choice (and in a slightly new climate)
    I was diagnosed with two quite serious conditions - neither curable, but one was preventable and the other was at this time preventable to a degree. I mean the condition would be one only (the result of "bad" accumulation +genes?), less serious and correctable.

    An insurance company has a tremendous incentive to reduce its costs and hence a great incentive to find out the truth. If they are not, it means that something is fishy. Why are insurers not commissioning their own studies? Are they not allowed to? Is it the regulators who are holding them back? Or are they actually stupid?

    I have not had any insurers say they know what a patient's lipid numbers are, but they can pretty well tell from claims data what tests have been done, and what medications are prescribed.

    We get faxes all the time recommending that meds be changed or weaned or made as needed rather than routine.  Yes, I know Mrs. Jones has been on an ulcer medicine for 6 months, and we should try to wean it.  What they don't know is that she won't change her diet and lose some weight, so maybe her symptoms would stop, and her symptoms get horribly worse without her ulcer medication.

    Dr. Davis,

    Based on Claudia's numbers, I guess I should expect a letter from my insurance company and a prescription from my doc for a statin. I won't fill the scrip.

    I'm 65, slim, eat VLC, and haven't been afraid of  saturated fat. But I just got my labs and TC was 476, HDL 146, Triglycerides 79 (I'd had wine with dinner--they're usually in the 30s), and LDL 314!!!

    How worried should I be about these numbers?

  • susan

    3/21/2011 1:57:39 AM |

    Hey Dr. Davis,

    At my last visit, my doctor mentioned my lipid numbers; but even he had to admit that my LDL (157) and TC (234) had improved (from 177 and 255), and the rest of my labs were all WNL. I generally eat low carb -- other than my recent indulgence in mini PB cups -- so I suspect that, as you indicated, the actual numbers are better than the official calculated numbers.

    My doc didn’t try to prescribe any meds this time. But at other visits he’s tried to guilt me into following the accepted guidelines by telling me his “performance score” is determined by how well he adheres to those guidelines, including prescribing all the meds and tests recommended by the so-called experts for a patient of my age with my lab results.

    I also fear that things are changing in this regard – and not for the better. Our government has now decided that we all must have insurance or pay a fine. If I refuse to follow the recommended guidelines, either my insurance company or my doctor, or both, may “fire” me. The truth is, I really don’t give a fig which entity it is (doctor, insurance company, or government panel) that tries to hector me into following guidelines promulgated by “experts” who believe in the lipid hypothesis. I simply choose to believe that I’m in charge of my body and that I get to determine whether to take a recommended med or have a recommended test.

    As for insurance companies getting lab results, I don’t know whether the doctor’s office or Quest Labs has been feeding my results to my insurance company, but when I look at my online health info on the insurance company’s web site, all my lab results are listed. And I’m sure the company is basing at least some of its many recommendations on those results.

    I must admit, having the results online makes it easy for me to keep track of them; but given the ease with which records can be hacked, I fear for my health privacy. And I resent the big brother attitude of the insurance company. I'm a well-informed, healthy adult. Treat me like one.

    I spent the weekend reading your older posts about LDL. I guess I need to get a test done to determine my LDL particle number before my doc and I have a discussion. Thanks for posting that info in such detail on your blog.
