The battle for natural hormones

18. April 2007 William Davis (0)

The battle for preservation of availability of compounded natural hormones goes on.

It started with pharmaceutical manufacturer, Wyeth, who petitioned the FDA to disallow the mixing of pharmaceuticals, especially natural human hormones, by specially trained pharmacists at what are called "compounding pharmacies." These are pharmacies that have special equipment and where trained pharmacists can mix up specific preparations for dispensing. These are available by prescription.

For instance, I have been prescribing natural human testosterone and progesterone for nearly 10 years. I have found service to be excellent, with lots of learning materials provided to patients by the pharmacy. The pharmacists I've spoken to have been courteous and knowledgeable. Compounded hormones are also shockingly less expensive. While a testosterone patch from a pharmaceutical company costs around $4.00 per day, the same quantity of testosterone cream formulated by a compouding pharmacy costs around $0.50 per day--87.5% less.

Wyeth hides behind a smoke screen of concern over quality. But the price differences tells the entire story: they want to eliminate the inexpensive competition and hold us all hostage to the far more expensive, often inferior products that they produce. They'd sooner force a woman to use horse-derived Premarin than to allow her access to human estrogens and progesterone.

To me, this is an outrageous affront to our freedom of choice, both as consumers as well as a physician. If you feel as strongly as I do about opposing the unfair and bullying ways of Wyeth Pharmaceuticals and the FDA, the P2C2 association of compounding pharmacists makes writing a letter to your Senator easy by going to

Lipitor and memory

17. April 2007 William Davis (2)

At first, I was skeptical. A book from a nutty author and physician named Duane Graveline kept on coming up in conversations with patients. His book, Lipitor: Thief of Memory , details his personal experience with dramatic changes in memory and thought while taking Lipitor.

Now this is a drug that I've seen used thousands of times. But I've now seen about a dozen people who have had distinct struggles with memory and clarity of thinking while taking Lipitor. Most took doses of 40 mg per day or more, though an occasional person takes as little as 10 mg. The association seems to be undeniable, since it improves after two weeks off the drug, recurs when resumed. Just today, I saw two people where this effect may be an issue.

Curiously, I've not seen it with any other statin agent. Unfortunately, uncovering any scientific data on the issue is a hopeless quest. Either it's very uncommon or, worse, the data has been suppressed.

Any way, I believe that Dr. Graveline was right: Lipitor, in a small number of people, does indeed seem to exert real detrimental effects on the mind.

If you take Lipitor, should you stop it in fear of long-term effects on your mental capacity? I think it's premature to toss the drug out based on this relatively uncommon relationship. This particular effect is likely to be idiosyncratic, i.e., peculiar to an occasional person but does not seem to apply to the majority, probably by some quirk of metabolism or penetrability of the barrier between the blood and nervous system tissue.

If, however, you feel that your thinking and memory have deteriorated on the drug, please speak to your doctor.

EKG's and heart disease

16. April 2007 William Davis (6)

How helpful are EKG's for detecting hidden heart disease?

I pose this question because several patients asked this question just this week. It's also a frequent point of confusion and misperception.

Your EKG is nothing more than an expression of the surface electrical activity emitted by heart muscle activity. Multiple (12) leads are attached to the body simply to provide various "views" of this electical activity. EKG, or sometimes "ECG", is short for "electrocardiogram".

What modifies this surface electrical activity? Anything that modifies the electrical activity within the heart itself, or interferes with the detection of the activity. An old heart attack modifies the patterns of electrical conduction in the heart and that can change your EKG. An ongoing heart heart attack likewise. High blood pressure commonly creates changes in the EKG, as does lung disease. A bellyache can change your EKG, as can a stroke. (These non-heart-related phenomena probably are often due to changes in autonomic, or "automatic," nervous system activity.) The heart generates electrical activity in a predictable sequence that generates the heart beat, or "rhythm". EKG's are useful for monitoring heart rhythm, also.

Does having plaque in your coronary arteries have any effect on the EKG? None whatsoever, unless plaque rupture caused heart attack or is about to cause heart attack. So, you can have a horrendous CT heart scan score of, say, 3000, yet maintain a perfectly normal EKG, as long as the heart muscle is normal.

Then why bother with these iffy tests? They are indeed useful to diagnose the cause of active symptoms. For instance, go to the ER with chest pain and an EKG could show changes suggesting that the chest pain is a heart attack. EKG's are also useful for future comparison. Any change in EKG can suggest certain things, like new heart rhythm disturbances unrelated to coronary plaque.

Think of your EKG as just like buying a used car. Say I'm trying to sell you my 1999 Buick Century. It looks pretty good from the outside and I tell you that it has 70,000 miles and runs well. You ask to open the hood, look in the interior and take it out for a drive. I tell you no, you can't do that.

Would you buy the car? Of course you wouldn't. You were permitted only a very superficial examination of the car. You have no idea what's going on inside. Just because the paint job looks brand new doesn't mean the engine and transmission are good.

The same with your EKG: It's a superficial look at one aspect of this used car called your heart. If the EKG is normal, that's good, just like a good exterior on the Buick. But you cannot assume that the heart is otherwise normal.

View the EKG as a simple, superficial test that can only provide minimal reassurance, no matter how often you have it done.

A new Track Your Plaque record

14. April 2007 William Davis (0)

Neal, a 40-year old school principal, and his young wife were terrified on learning of his CT heart scan score of 339, a concerningly high score for any age, particularly age 40.

To make matters worse, all of Neal's plaque was located in the critical left mainstem coronary artery, the shared stem of two of the three coronary arteries. A heart attack in this location is instantly fatal.

So, it was especially gratifying that Neal has set the Track Your Plaque record for largest magnitude of plaque reversal: 51% in his first year.

Studies that show a reduction in heart attack make the news. They talk about 1, 2, up to 6% regression, all achieved with high doses of statin drugs. Yet we are seeing huge, extraordinary quantities of heart disease reversal that haven't yet made headlines, amounts that far exceed those featured in the news. We should be encouraged by experiences like Neal's.

Watch for the upcoming Track Your Plaque newsletter for more details on Neal's story--how he came to the program, how he accomplished this huge effect, and why his experience was such a success.

The Plavix Scam

12. April 2007 William Davis (3)

Periodically, I'll see a flurry of TV ads for Plavix. It comes with a polished computer-animated cartoon that shows how platelets clump and form a blood clot, causing heart attack.

Imagine there's a pile of oil-soaked rags in a corner of your garage. I come by and tell you to get a good fire extinguisher to keep next to the rag pile in case they spontaneously ignite.

Does that make sense to you?

Wouldn't it be better to get rid of the oily rags and forget about the fire extinguisher?

Plavix is the fire extinguisher. The oil rags are your coronary plaque. The solution is to gain control over plaque behavior. Unfortunately, the TV ads (intentionally, I suspect) give the impression that blood clots just form out of the blue for no reason. Of course that's not true. It requires active, growing, inflamed atheroslcerotic plaque that ruptures, uncovering the "angry" and platelet-adhering material underneath the thin covering or endothelial lining.

Urging everybody to take Plavix is absurd. The TV ads urge many people who have no business taking the drug to take it. There are, without a doubt, groups of people who are better off taking Plavix and aspirin: people who are in the midst of heart attack, people who have unstable plaque, people with recent stents or bypass. Perhaps people at high risk for plaque rupture, e.g., extensive coronary plaque that has continued to grow.

These tactics are consistent with the experiences I've had with the sales representatives from the company (when I used to actually talk to sales reps; my office is now barred from them). The reps very aggressively would urge me to consider having everyone take Plavix. No kidding.

For us, i.e., for people who just have a heart scan score but interested in engaging in a powerful program of prevention and reversal, Plavix rarely provides any advantage. The answer is, just like our oily rag analogy, control the plaque, not put out the fire.

Lipoprotein(a) and small LDL

11. April 2007 William Davis (0)

You won't find a lot of scientific validation for this, but it is my firm impression that small LDL, by some crazy means, has the capacity to "turn on" or "turn off" lipoprotein(a), Lp(a).

Recall that Lp(a) is a specific genetic trait, passed to us (if you have it) by mother or father. It falsely elevates LDL cholesterol and escalates heart disease risk more than just about any other known abnormality.

A frequent hint that Lp(a) might be present is a comment I hear often from patients: "My doctor said statin cholesterol drugs don't work for me. I tried them all and my cholesterol won't go down." Or, the result was substantially less than expected. That's because, when Lp(a) is lurking in your cholesterol value, it is unaffected by the statins.

It's been my in-the-trenches observation that, the more fully expressed the small LDL pattern becomes, the worse the Lp(a) behaves. In other words, if small LDL is suppressed effectively, Lp(a) doesn't seem to carry the same dangers as in someone who has plenty of small LDL. I don't know why this is. (I expect that the answer will come from someone like Dr. Marcovina at Stanford, who is at the forefront of Lp(a) structural research. Lp(a) is a complex molecule with several components. How and why it interacts with other particles remains a mystery.)

There are a little bit of data to confirm this. The Quebec Cardiovascular Study has presented some data to this effect, that the combination of small LDL particles and Lp(a) are a particularly lethal combination. We are trying to correlate our data from a CT heart score perspective to discern any statistical relationships.

This raises a very important therapeutic issue if you have Lp(a): the worst thing you can do if you have Lp(a) is become overweight. Excess abdominal fat is a huge trigger to create small LDL particles. Even though being overweight itself has no effect on the measured level of Lp(a), it activates small LDL which, in turn, throws gasoline on the Lp(a) fire.

If you have Lp(a), stay skinny.

Optimal medical therapy

9. April 2007 William Davis (6)

I was re-reading some of the details behind the recently announced COURAGE Trial comparing angioplasty/stent in 1100 people compared to "optimal" medical therapy in another 1100. You'll recall that no difference was found.

In particular, over approximately 5 years, 20% of participants in each group died, experienced heart attacks, or strokes. Of those treated with "timal" medical therapy, 32% ended up getting a procedure like stents or bypass anyway due to deteriorating symptoms.

What is "optimal" medical therapy? I bring this up again because the study investigators in COURAGE, as well as in similar trials, say this with a straight face. Optimal medical therapy means aspirin and/or Plavix (the anti-platelet, aspiri>My Particles are Bigger than Your Particles
Why consuming plenty of "healthy whole grains" is the path to heart disease and heart attack and why saying goodbye to them is among the most powerful strategies around for reduction or elimination of risk.

Hello, Intestine: It's Me, Wheat
No discussion of wheat is complete without talking about how celiac disease and other common intestinal ailments, like acid reflux and irritable bowel syndrome, fit into the broader concept of wheat elimination.

Good fat, bad fat

27. August 2011 William Davis (11)

No, this is not a discussion of monounsaturated versus hydroxgenated fat. This is about the relatively benign fat that accumulates on your hips, rear end, or arms--the "good"--versus the deep visceral fat that encircles your intestines, kidneys, liver, pancreas, and heart--the "bad."

And I'm not talking about what looks good or bad. We've all seen the unsightly flabby upper arms of an overweight woman or the cellulite on her bulging thighs. It might look awful but, metabolically speaking, it is benign.

It's that muffin top, love handle, or wheat belly that encircles the waist, a marker for underlying deep visceral fat, that:

--Increases release of inflammatory mediators/markers like tumor necrosis factor, leptin, interleukins, and c-reactive protein
--Is itself inflamed. When examined under a microscope, visceral fat is riddled with inflammatory white blood cells.
--Stops producing the protective hormone, adiponectin.
--Traffics in fatty acids that enter the bloodstream, resulting in greater resistance to insulin, fat deposition in the liver (fatty liver), and increases blood levels of triglycerides
--Predicts greater cardiovascular risk. A flood of recent studies (here's one) has demonstrated that larger quantities of pericardial fat (i.e., visceral fat encircling the heart, visible on a CT scan or echocardiogram) are associated with increased likelihood of coronary disease and cardiovascular risk.

You can even have excessive quantities of bad visceral fat without much in the way of fat elsewhere. You know the body shape: skinny face, skinny arms, skinny legs . . . protuberant, flaccid belly, the so-called "skinny obese" person.

Nobody knows why fat in visceral stores is so much more evil and disease-related than, say, wheat on your backside. While you may struggle to pull your spreading backside into your jeans, it's waist girth that is the problem. You need to lose it.

You could take vitamin D or . . .

26. August 2011 William Davis (53)

You could take vitamin D and achieve a desirable blood level of 25-hydroxy vitamin D (I aim for 60-70 ng/ml), or you could:

--Take Actos to mimic the enhanced insulin sensitivity generated by vitamin D
--Take lisinopril to mimic the angiotensin-converting enzyme blocking, antihypertensive effect of vitamin D
--Take Fosamax or Boniva to mimic the bone density-increasing effect of vitamin D
--Take Celexa or other SSRI antidepressants to mimic the mood-elevating and winter "blues"-relieving effect of vitamin D
---Take Niaspan to mimic the HDL-increasing, small LDL-reducing effect of vitamin D
--Take naproxen to mimic the pain-relieving effect of vitamin D

So, given a choice, what do most doctors choose? Of course, they choose from the menu as presented by the sexy sales representative sitting in the office waiting room. These medications, of course, are among the top sellers in the drug world, taken by millions of Americans and not just one at a time, but several per person.

The Food and Nutrition Board of the Institute of Medicine, the panel of volunteers charged with drafting a Recommended Daily Allowance for vitamin D, says that you are already getting enough vitamin D, so don't bother taking any supplements and continue to wear your sunscreen. Wonder whose side they're on?

I continue to be impressed that many of the conditions that plague modern people are little more than deficiencies peculiar to modern life, such as vitamin D deficiency, or the result of the excesses of modern life, such as consumption of sucrose, fructose, corn, and "healthy whole grains."

I take 8000 units of gelcap vitamin D and haven't felt better.

More lipoproteins zero!

26. August 2011 William Davis (18)

A few posts back, I talked about how more people are showing us zero lipoprotein(a) and zero small LDL. That was about 4 weeks ago. By then, I had seen 3 people with zero values on both.

Well, it's now up to 9 people: 9 people who have achieved zero lipoprotein(a) and zero small LDL. These are people who started with typical lipoprotein(a) values of 150-300 nmol/L and small LDL values of 1000-2000 nmol/L, both substantial.

I still don't know how many people or what percentage can expect to show such extravagant results. But the sharp increase over a relatively brief period of time is extremely encouraging!

Diet: One size does NOT fit all

24. August 2011 William Davis (33)

Heart Scan Blog reader, Frustrated, posted this comment:

Dr. Davis,
I have spent the last 5 months eating a diet that completely eliminated all wheat products. It was very low carb, and consisted of relatively high protein (eggs, grass fed beef, grass fed raw cheese, oily fish, chicken), good level of olive oil, walnuts, fish oil (3 mg per day), raw vegetables, little bit of fruit. So I had good amount of monounsaturated fat as well as saturated fat from eggs and grass fed products.

My recent NMR showed:
LDL-p. 2,800
Small LDL particle 1700
Small HDL particle 20
HDL-C 40
LDL-C 114
Trigs. 224
Total chol 208

So I was disappointed. Where have I gone wrong? No wheat and sky-high LDL-p and 1700 small LDL particles.

This is indeed unusual. I see this perhaps 5 or 6 times over a year's time, while thousands of other people show the usual expected respone. I don't have Frustrated's lipoprotein panel prior to starting the diet, but I'll bet the starting panel was similar to this "after" panel.

The overwhelming majority of people who follow a diet like the one described--no wheat, limited carbohydrate, grass fed beef, fish, chicken, vegetables, limited fruit--obtain extravagant reductions in small LDL, increased HDL, and reduced triglycerides. So why did Frustrated end up with such disappointing results, values that potentially provide for high risk for heart disease?

There are several possibilities:

1) He/she is in the midst of substantial weight loss. When labs are drawn in the midst of weight loss, stored energy is being mobilized into the blood stream. This energy is mobilized as fatty acids and triglycerides which, upon entering the blood stream, cause increased triglycerides, reduced HDL, chaotic or unpredictable small LDL patterns, and increased blood sugar sufficient to be in the diabetic or pre-diabetic range. This all subsides and settles down to better values around 2 months after weight loss has plateaued.

2) Apo E4--If Frustrated has one or two apo E4 genes, then increased dietary fat will serve to exaggerate measures like small LDL despite the reduction in carbohydrates, LDL particle number, and triglycerides. This is a tough situation, since small LDL particles and high triglycerides signal carbohydrate sensitivity, while apo E4 makes this person, in effect, unable to deal with fats and dietary cholesterol. It gives me the creeps to talk about reducing fat intake, but this becomes necessary along with carbohydrate restriction, else statin drugs will come to the "rescue."

3) Apo E2 + Apo E4--It's possible that an apo E2 is present along with apo E4. Apo E2 makes this person extremely carbohydrate-sensitive and diabetes-prone with awful postprandial (after-meal) persistence of dietary byproducts, alongside the hyperabsorption of fats and dietary cholesterol from apo E4. This is a genuine nutritional rock and a hard place.

4) Other variants--There are probably a dozen or more other genetic variants, thankfully rare, such as apo B and apo C2 variants, that are not generally available for us to measure that could influence Frustrated's response.

5) The low-carb diet is not truly low-carb--Frustrated sounds like a pretty sharp cookie. But it's not uncommon for someone to overlook a substantial source of carbohydrate exposure that triggers these patterns. Fruit is a very common tripping point, since people generally regard unlimited fruit as a healthy thing. This does not seem to be Frustrated's problem. Others indulge in quinoa, sweet potatoes, millet or other carbohydrate sources that look and sound healthy but, in sufficient quantities, can still trigger this pattern.

6) Other--Hypothyroidism, kidney disease, nephrotic syndrome, hypercortisolism and some other relatively rare conditions are worth considering if none of the above apply.

Anyway, that's the list I use when this peculiar situation arises. If obvious weight loss is not the culprit, the next step is apo E testing. However, the wrong response is to reject the low-carbohydrate notion altogether and just limit fat, since this typically leads to uncontrolled small LDL, high triglycerides, and diabetes. It can often mean limiting carbohydrates while also limiting fats. Just as with the combination of apo E4 with Lipoprotein(a), I lump many of these patterns into the emerging world of genetic incompatibilities, genetic traits that code for incompatible metabolic phenomena.
