Can I stop my Coumadin?

Here I go again.

While I will try to keep this blog on topic, i.e., coronary heart disease prevention and reversal using nutritional and other natural strategies, I believe that a "critical mass" of frequently asked, though off topic, questions keep cropping up.

One such question revolves around Coumadin, or warfarin.

Somehow, my Nattokinase scam blog post draws traffic about Coumadin. I tried to make the point that a conventional blood thinning agent like Coumadin that undoubtedly has undesirable side-effects cannot be replaced by an agent that has an uncertain track record. In the case of nattokinase, no track record.

To illustrate how far wrong the "nattokinase as replacement for Coumadin" idea can go, here is a question from Anna:


I came across your blog while perusing.

I am a bit bummed because I have been on Coumadin (warfarin) for around 22 years since I was 6 years old. I have a mechanical heart valve (St. Jude's), as I have heart-related issues, including hypertrophic obstructive cardiomyopathy.

Well, it is just that the warfarin seems to interact with nearly everything. I feel like I can not get the nutrients my body requires. I desire to consume more raw foods and vegan foods, though I do not want anything to damage my heart valve or risk a stroke/heart attack or internal bleeding.

I have been underweight the majority of my life, malnourished , currently am still somewhat underweight, though enjoying food again, as I had what mimicked Crohn's Disease for several years (horrendous pain), from which I am in remission now. I was diagnosed with osteoporosis, which may or may not be caused from consuming warfarin.

Is it possible to get off of warfarin and effectively keep my blood thinned ? I currently take 1.5 mg to 2 mg dosage. Does the warfarin destroy Vitamin K and if so does that mean while on warfarin I never get the Vitamin K nutrients even if I did consume foods with it in it?

Thank you
Anna


No, sorry, Anna. Stopping Coumadin with your unique issues, i.e., a prosthetic mechanical heart valve (likely mitral, judging by your history of hypertrophic obstructive cardiomyopathy, in which the patterns of blood flow ejected from the heart disrupt the natural mitral valve function) and cardiomyopathy, can be fatal. Without blood thinning, the mechanical heart valve can trigger blood clot formation, since it is a foreign object implanted into the bloodstream.

There are no natural alternatives available with track records confident enough to bet your life on. Aspirin nor Plavix are blood thinners, but platelet inhibitors. These two agents, while they work for other forms of arterial (but not venous) blood clot inhibition, will not work for your unique situation.

Likewise, a purported oral lytic agent like nattokinase should not be substituted for Coumadin. Even if there was plausible science behind it, you should demand substantial evidence that it provides at least blood thinning equivalent to Coumadin. Should a blood clot, even a small one, form in or around the prosthetic valve, the valve can stop working within seconds. This can lead to death within minutes.

I believe it would be foolhardy to bet your life based on the marketing--let me repeat: MARKETING--of a "nutritional supplement" by supplement manufacturers eager to make a buck.

Nor are there any other nutritional supplements that can safely replace the Coumadin. I wish that were NOT true, as I am no stranger to the long-term dangers of Coumadin and I am a big believer, in general, in nutritional supplements. I am a BIGGER believer, however, in the truth. Weighing the options available to us today, there really is no rational choice but to remain on Coumadin.

By the way, I tell my patients to eat a substantial amount of green vegetables while they take Coumadin. I know that conventional advice is to reduce or eliminate green vegetables due to their content of Coumadin-antagonizing vitamin K. I think this is wrong, also. Green vegetables are the best foods on earth. They reduce risk for cancer, diabetes, bone disease, and coronary heart disease.

To obtain the benefits of green vegetables without mucking up your blood thinning (your "protime" or International Normalized Ratio, INR), I advise my patients who take Coumadin to eat green vegetables--but do so every day in relatively consistent quantities, so that the protime or INR is not disrupted and remains reasonably constant. It may mean that your total dose of Coumadin may be somewhat higher, e.g., 3 or 4 mg instead of 2 mg, but the dose is immaterial outside of blood thinning. That way, you obtain all the wonderful health benefits of green vegetables while maintaining fairly consistent blood thinning/protime/INR. Coumadin does not block all the health benefits of vegetables, only those related to vitamins K1 and K2.

With regards to protecting yourself from the osteoporosis promoting effects of Coumadin, I would be sure to follow a program of natural bone health, such as the one I discussed in Homegrown osteoporosis prevention and reversal. You will have to be extra careful, however, with the vitamin K2. Ideally, you have a doctor knowledgeable about vitamin K2 who can assist you in managing K2 intake while on Coumadin. This is something you can definitely NOT manage on your own. (I am a big believer in self-managed care, but this is way beyond the limit.)

Lastly, it is my belief that anyone with an inflammatory bowel condition, such as Crohn's disease or ulcerative colitis, should absolutely, positively, and meticulously AVOID WHEAT and all other gluten sources (such as rye, barley, and oats). Even if you test negative for celiac markers (e.g., anti-gliadin antibodies, emdomysium and transglutaminase antibodies), the enhanced intestinal permeability will allow wheat proteins, such as gluten, to gain ready entry into the bloodstream. Not to mention that wheat should have no place in the human diet anyway, in my view.

Homegrown osteoporosis prevention and reversal

I don't like to stray too far off course from discussions of heart disease and related issues in this blog. But the question of bone health comes up so often that I thought I'd discuss the strategies available to everybody to stop, even reverse, osteoporosis.

Coronary atherosclerotic plaque and bone health are intimately interwoven. People who have coronary plaque usually have osteoporosis; people who have osteoporosis usually have coronary plaque. (The association is strongest in females.) The worse the osteoporosis, the greater the quantity of coronary plaque, and vice versa. The two seemingly unconnected conditions share common causes and thereby respond to similar treatments.

Incredibly, rarely will your doctor tell you about these strategies. Your doctor orders a bone density test, the value shows osteopenia or osteoporosis, and a drug like Fosamax or Boniva is prescribed. As many people are learning, drugs like this can be associated with severe side-effects, such as jaw necrosis (death of the jaw bone), a dangerous and disfiguring condition that leads to loss of teeth and disfigurement, followed by reconstructive surgery of the jaw and face. These are not trivial effects.

Note that drugs are approved by the FDA based on assessment of efficacy and safety, NOT proven equivalence or superiority to natural treatments.

In order of importance (greatest to least), here are strategies that I believe are important to regain or maintain bone health. Indeed, I have seen many women increase bone density using these strategies . . . without drugs of any sort.

1) Vitamin D restoration--Vitamin D is the most important control factor over bone calcium metabolism, as well as parathyroid function. As readers of this blog already know, gelcap forms of vitamin D work best, aiming for a 25-hydroxy vitamin level of 60-70 ng/ml. This usually requires 6000 units per day, though there is great individual variation in need.

2) Vitamin K2--If you lived in Japan, you would be prescribed vitamin K2. While it's odd that K2 is a "drug" in Japan, it means that it enjoys the validation required for approval through their FDA-equivalent. Prescription K2 (as MK-4 or menatetranone) at doses of 15,000-45,000 mcg per day (15-45 mg), improves bone architecture, even when administered by itself. However, K2 works best when part of a broader program of bone health. I advise 1000 mcg per day, preferably a mixture of the short-acting MK-4 and long-acting MK-7. (Emerging data measuring bone resorption markers suggest that lower doses may work nearly as well as the high-dose prescription.)

3) Magnesium--I generally advise supplementation with the well-absorbed forms, magnesium glycinate (400 mg twice per day) or magnesium malate (1200 mg twice per day). Because they are well-absorbed, they are least likely to lead to diarrhea (as magnesium oxide commonly does).

4) Alkaline potassium salts--Potassium as the bicarbonate or the citrate, i.e., alkalinizing forms, are wonderfully effective for preservation or reversal of bone density. Because potassium in large doses is potentially fatal, over-the-counter supplements contain only 99 mg potassium per capsule. I have patients take two capsules twice per day, provided kidney function is normal and there is no history of high potassium.

5) An alkalinizing diet--Animal products are acidic, vegetables and fruits are alkaline. Put them together and you should obtain a slightly net alkaline body pH that preserves bone health. Throw grains like wheat, carbonated soft drinks, or other acids into the mix and you shift the pH balance towards net acid. This powerfully erodes bone. Therefore, avoid grains and never consume carbonated soft drinks. (Readers of this blog know that "healthy, whole grains" should be included in the list of Scams of the Century, along with Bernie Madoff and mortgage-backed securities.)

6) Strength training--Bone density follows muscle mass. Restoring youthful muscle mass with strength training can increase bone density over time. The time and energy needs are modest, e.g., 20 minutes twice per week.

Note that calcium may or may not be on the list. If on the list at all, it is dead last. When vitamin D has been restored, intestinal absorption of calcium is as much as quadrupled. The era of force-feeding high-doses of calcium are long-gone. In fact, calcium supplementation in the age of vitamin D can lead to abnormal high calcium blood levels and increased heart attack risk.

These are benign and easily incorporated strategies. They are also inexpensive. I challenge any drug to match or exceed the benefits of this combination of strategies. Keep in mind that strategies like vitamin D restoration provide an extensive panel of health benefits that range far beyond bone health, an effect definitely NOT shared by prescription drugs.

Your enlarged aorta

The thoracic aorta lives happily within the chest.

The aorta is the main artery of the body that emerges from the heart, located just under the sternum. It is the "tree trunk" from which all the major arteries branch off to the rest of the body: the arms, brain, abdominal organs, pelvis, and legs. The aorta receives the high-pressure blood ejected directly out of the heart muscle.

However, there are evil forces in the body that work to weaken the aorta. When the aorta is weakened, it enlarges. Enlarged aortas also tend to grow atherosclerotic plaque. Plaque in the aorta poses long-term risk for stroke and and mini-strokes ("transient ischemic attacks," or TIAs), due to fragmentation.

There are many enlarged aortas in this world. I see at least several every week. It is fairly common, particularly in people with high blood pressure and cholesterol abnormalities, as well as those who are overweight. Smokers get it really bad.

Conventional thinking is that, once an aorta enlarges, it will inevitably continue to enlarge at the average rate of 2.0 mm per year (resulting in 1.0 cm enlargement over 5 years). For this reason, conventional discussions on the topic of thoracic aortic aneurysms all say something like "Enlarged aortas should be monitored yearly. Surgical replacement should proceed when the aorta reaches a diameter of 5.5 cm."

This is because an aortic diameter of 5.5 cm is associated with much greater likelihood that the aorta will rupture (fatal within minutes) or the internal lining will tear, a "dissection." The surgery is a major undertaking that involves opening the chest and usually replacing the aortic valve and inserting a synthetic aorta. The procedure is high-risk, especially if any branch arteries are involved.

So putting a stop to any further aortic enlargement is a worthwhile goal. Unfortunately, conventional thought is that there is nothing you can do to stop the inevitable growth of the thoracic aorta.

Nonsense. There are a number of efforts you can make to halt further increase in aortic diameter. (My experience in this is anecdotal and unpublished, but now numbers several hundred patients.)

There are two categories of factors that cause the aorta to increase in diameter:

1) Internal pressure--Think of blood pressure as the internal inflating pressure on this "balloon." Keeping the "inflating pressure," i.e., blood pressure, low exerts substantial effect on slowing growth of aortic diameter. I aim for normal BP or lowish BP (less than 130/80, preferably 100/70).

2) Factors that weaken the aortic wall--Processes like inflammation, glycation, lipoprotein deposition, and nutritional deficiencies will serve to weaken the supportive tissue of the aorta. For that reason, correction of lipoprotein abnormalities (e.g., small LDL and lipoprotein(a)), reductions in carbohydrate intake and thereby blood glucose/glycation, and "normalization" of vitamin D, vitamin C supplementation (for collagen crosslinking), and omega-3 fatty acids all play a role.

To push even farther, there may be additional advantage to following strategies that impair the production and activity of a crucial enzyme that lives within the aortic wall: matrix metalloproteinase, or MMP. MMP degrades the collagen and other supportive tissues within the aorta, weakening it and permitting expansion. Blocking MMP may prove to be among the most powerful new strategies to halt aortic expansion.

Compounds that have potential MMP-inhibiting effects include:
--Vitamin D--A substantial effect
--Resveratrol--One of the polyphenols from red wine
--Doxycycline--This old antibiotic often used for acne treatment has, in preliminary studies, shown important MMP-blocking effects and slowed aortic expansion.

Anyway, there you have it. A bit complicated, but a "recipe" that has failed me only rarely.

Extreme carbohydrate intolerance

Here's an interesting example of what you might call "extreme carbohydrate intolerance."

May is a 44-year woman who has now had her 7th stent placed in her coronary arteries. She lives on a diet dominated by breads, breakfast cereals, muffins, rice, corn products, along with some real foods.

Her conventional lipid panel and other lab values:

Total cholesterol 346 mg/dl
Triglycerides: 877 mg/dl
HDL cholesterol: 22 mg/dl
LDL cholesterol: incalculable
(Recall that LDL cholesterol is usually a calculated, not a measured value. The excessively high triglycerides make the standard calculation invalid--more invalid than usual.)

Fasting blood glucose: 210 mg/dl
HbA1c (a reflection of previous 60-90 days average glucose): 7.2% (desirable 4.5% or less)
ALT (a "liver enzyme"): 438 (about five-fold normal)


At 5 ft even and 138 lbs (BMI 27.0), May appears small. But the modest excess weight is all concentrated in her abdomen, i.e., in visceral fat.

By lipoprotein analysis via NMR (Liposcience), May's LDL particle number was 2912 nmol/L, or what I would call a "true" LDL of 291 mg/dl. (Drop the last digit.) Of the 2912 nmol/L LDL particles, 2678 nmol/L, or 92%, were small.

The bad news: This pattern of extremely high triglycerides, extremely high LDL particle number, low HDL, predominant small LDL, and diabetes poses high-risk for heart disease--no surprise. It earned her 7 stents so far. (Unfortunately, she has made no effort whatsoever to correct these patterns, despite repeated advice to do so.)

The good news: This collection is wonderfully responsive to diet. LDL particle number, small LDL, triglycerides, blood glucose, and HbA1c drop dramatically, while HDL increases. Heart disease will at least slow, if not stop.

It's amazing how far off human metabolism can go while indulging in carbohydrates, particularly a genetically carbohydrate-intolerance person. (Actually, I wouldn't be surprised if May's diet, as bad as it seems to you and me, still fits within the dictates of the USDA food pyramid.) The crucial step in diet to correct this smorgasbord of disaster is elimination of carbohydrates, especially that from wheat, cornstarch, and sugars.

What's for breakfast? Egg bake

Heart Scan Blog reader and dietitian, Lisa Grudzielanek, provided this recipe in response to the post, What's for breakfast?

Lisa, by the way, is one of the rare dietitians who understands that organizations like the American Dietetic Association have made themselves irrelevant. She therefore advocates diet principles that work, not just echoing the idiocy that emanates from such organizations, often driven by economics more than science. Lisa works in the Milwaukee area and has proven a useful resource person for my patients who have required extra coaching in the Track Your Plaque diet principles.

Egg Bake
My favorite breakfast is what I call an "egg bake." Others may refer to it as a "quiche."

Take a variety of fresh vegetables. This time of year is great for farmers' markets.

I typically use fresh chopped organic spinach, bell peppers, red & white onions, scallions, broccoli, mushrooms, cherry tomatoes halved and, if desired, meat (nitrite-free ham or leftover chicken breasts).

1) Chop veggies and place in casserole dish.
2) Add meat and handful of cheese of your choice.
3) Scramble 8 eggs & little bit of milk & pepper.
4) Add to casserole dish and mix/coat veggies with egg mixture.
5) Put in oven at 450 degress for 30 minutes.

Yummy, ready to eat breakfast that is so easy for the work week.

What's for breakfast?

If you eliminate wheat from breakfast and otherwise adhere to a low-carbohydrate dietary approach, what is there to eat for breakfast?

If you take out English muffins, bagels, all breakfast cereals, pancakes, waffles, and toast, what's left to eat?

Actually, there's plenty left to eat. It just may not look like the traditional American notion of "breakfast." (The traditional idea of breakfast was is, in part, due to the legacy of Dr. John Harvey Kellogg, who, in the latter part of the 19th century, ran a sanitarium in Battle Creek Michigan. He and his brother, Will Keith Kellogg, discovered the idea of turning grains into flakes, the birth of the breakfast cereal. Subscribe to the idea of breakfast cereal for breakfast and you subscribe to the ideas of a man who would administer four enemas for you today to cure your cancer or rheumatism.)

Here are a few ideas. By no means is this meant to be a comprehensive list, just a starting point for a few new breakfast food ideas.

--Eggs--Of course, eat the yolk. Eat three yolks. Scrambled, "fried," (not really deep-fried, of course), hard-boiled, poached, as an omelette. Add pesto, olive oil, vegetables, mushrooms, salsa.

--Ground flaxseed--As a hot cereal with your choice of water, milk (not my favorite because of insulin effects; the fat is immaterial), full-fat soy milk (yeah, yeah, I know), unsweetened almond milk. Add walnuts, blueberries, etc. Ground flaxseed is the only grain I know of that contains no digestible carbohydrates.

--Lunch and dinner--Yes, if you cannot have breakfast foods for breakfast, then have lunch and dinner, meaning incorporating foods you ordinarily regard as lunch and dinner foods into your day's first meal. This means salads, leftover chicken from last night, soup, raw vegetables dipped in hummus or guacamole, stir fry, etc.

--Cheese--For something quick, grab a chunk of gouda or emmentaler along with a handful of raw almonds, walnuts, or pecans. Because of the excess acidity of cheese (along with meats, among the most acidifying of foods), I usually try to include something like a raw pepper or avocado, foods that are net alkaline.

--Avocados--Cut in half, scoop out contents. They're quick and delicious, when available.

I hesitate to mention it, but I sometimes will have tofu, cubed and flavored with whatever is available--soy sauce, miso, pickled vegetables. My mother was Japanese, so I'm comfortable with this, though many people are not.

Anyway, that's a partial list that nonetheless can get you started on a wheat-free, low-carb breakfast.

If you are just starting out, you will notice a number of fundamental changes. You may first experience the characteristic "withdrawal" effect: mental fog and fatigue that lasts about a week. Energy then picks up, often substantially. This is followed by gradually reduced appetite: You will be far less hungry. You will require less food, less often, since appetite will be driven by physiologic need, not the appetite-stimulating properties of wheat (and cornstarch, high-fructose cornsyrup and sucrose).

By the way, do not skip breakfast unless it's part of an occasional fasting effort. Skip breakfast, wind down metabolism, get fat. I am impressed at how consistent skipping breakfast backfires in those who think that it helps you control weight.

I also welcome any suggestions on what you eat as part of your wheat-free, low-carb breakfast. (Thanks for the great suggestions on the last blog post, Anna.)

Wheat hip

You've heard of wheat belly. How about wheat hip?

Recall that the innocent appearing wheat belly is actually a hotbed of inflammatory activity beneath the surface. The visceral fat of the wheat belly, i.e., fat kidneys, fat liver, fat intestines, fat pancreas, produces abnormal inflammatory signals, such as various interleukins, tumor necrosis factor, and leptin. These are the inflammatory signals that create insulin resistance and diabetes, heart disease, hypertension, and cancer.

These same inflammatory mediators are able to enter the joint spaces, such as those in your hips, knees, and hands. This leads to osteoarthritis, the exceptionally common form of arthritis that affects 1 in 7 Americans. In particular, the level of leptin in joints mirrors that in blood, a phenomenon that has been associated with joint destruction.

The previously widely-held notion that arthritis is simply a wear-and-tear phenomenon due to the mechanical stress of excess weight is proving to be an oversimplification. Arthritis is also part of the carbohydrate-driven, weight-increasing, inflammatory condition of insulin resistance or metabolic syndrome.

Throw into this cytokine storm the fact that glycation, i.e., glucose modification of proteins, also causes cartilage destruction. The cells of human cartilage lack the ability to divide, so the cartilage cells you had at age 18 are the cartilage cells that you will hopefully still have at age 80. However, high blood sugars (glucose) glycate the proteins in cartilage. (Wheat raises blood glucose higher than almost all other foods, higher than a Milky Way bar, higher than a Snickers bar.) The process is irreversible and cumulative. Because cartilage has next to no capacity for repair or regeneration, it becomes brittle. Over years, it essentially crumbles, leading to the "bone on bone" that prompts conversations about total hip and total knee replacement.

So that ciabatta or blueberry muffin in your mouth takes you a step or two closer to joint destruction via heightened inflammation arising from the visceral fat of the wheat belly, worsened by glycation of high blood sugars after carbohydrate consumption.

My solution: Lose the ciabatta.

Men's lingerie is on the second floor

Consume wheat products, like poppyseed muffins, raisin bagels, and whole grain bread, and you trigger the 90- to 120-minute glucose-insulin cycle.

Blood glucose goes way up (more than almost any other known food), triggering insulin release from the pancreas. Glucose enters cells as a result, blood glucose plummets. You get hungry, shaky, and crabby, reach for another wheat or other sugar-generating food to start the roller coaster ride all over again.

Repetitive insulin triggering grows this thing I call a "wheat belly," the protuberant, hang-over-the-belt fat you see everywhere nowadays. Wheat belly fat is really visceral fat. Visceral fat means you have fat kidneys, fat intestines, fat pancreas, and fat liver, all causing the belly to protrude in the familiar way we've all come to recognize.

Visceral fat is special fat. Unlike the fat in the backside, thighs, or arms, visceral fat triggers inflammatory responses that are evident in such measures as tumor necrosis factor, interleukins, and leptin, as well as drops in the protective hormone, adiponectin.

Visceral fat also, oddly, triggers estrogen release. Estrogen triggers growth of breast tissue. That's why females with wheat bellies have up to four-fold (400%) greater likelihood of breast cancer.

Men also experience excess estrogen from the visceral fat wheat belly, causing "man boobs." This B-cup phenomenon means that inflammation is raging beneath the surface, all due to this thing you're wearing around your waist.

I wasn't aware until recently that male breast reduction surgery is a booming business growing at double-digit rates. So are special clothes to help men conceal their expansive breasts.

Perhaps the USDA is in cahoots with Playtex.

10,000 units of vitamin D

Joanne started with a 25-hydroxy vitamin D level of 23 ng/ml--severe deficiency.

What made this starting value even worse was that it was drawn in August after a moderately sunny summer spent outdoors. (Last summer, not this summer.) It therefore represented her high for the year, since vitamin D levels trend lower as fall and winter set in. This suggests that her winter level was likely in the teens or even single digits. In addition, note that, at age 43, Joanne has lost much of her ability to activate vitamin D in the skin.

So I advised that she take 6000 units of an oil-based gelcap per day, a dose likely to generate the desired blood level, which I believe is 60-70 ng/ml.

Four months later, her 25-hydroxy vitamin D level: 39.9 ng/ml--still too low. So I advised her to increase her dose to 10,000 units per day. Several months later, her 25-hydroxy vitamin D level: 63.8 ng/ml--perfect.

However, on hearing that she was taking 10,000 units vitamin D per day, Joanne's primary care physician was shocked: "What? Stop that immediately! You're taking a toxic dose!" So Joanne called me to find out if this was true.

No, of course it's not true. It's not the dose that's toxic, but the blood level it generates. Although it varies, vitamin D toxicity, as evidenced by increased blood calcium levels, generally does not even begin to get underway until at least 120-130 ng/ml, perhaps higher. Rarely, a dose of 2000 units per day will generate a level this high. In others, it may require 24,000 or more units per day to generate such a high level.

So it's not the dose that's toxic, but the blood level of 25-hydroxy vitamin D it generates.

Provided you and/or your doctor are monitoring 25-hydroxy vitamin D blood levels, the dose is immaterial. It's the blood level you're interested in.
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.

    and when she refuses to do as ordered, her insurance company will find out about that, and will then terminate her coverage. Anybody want to make a bet? So much for privilege and confidentiality in the ole US of A.

    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!

    Thanks for catching that, Teresa.

    It is indeed an eye-opener, isn't it?

    Anne and Kris--

    Fascinating non-American perspectives.

    Insurance companies have incredible info on us. I'm always surprised more is not made of this issue.

    Remember: The more they know, the better they are at denying coverage.

    Dr. Davis,

    I didn't want to put this here (not sure if I could post it elsewhere) , but I thought you would find this interesting if you haven't seen it yet.

    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?

    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.

    Just this past week, my insurance company (Aetna), which has paying for my test strips for the past year and a half, sent me a letter suggesting that I might have diabetes, and should talk to my doctor.

    Hi Dr. Davis,

    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.
