Heart scan curiosities 1 27. November 2006 William Davis (3) Heart scans often reveal more than coronary plaque. From time to time, I'll show some curious findings that people have displayed during routine heart scans. This 65-year old man had a relatively low heart scan score of 73, but showed an impressive quantity of calcification of his pericardium, the usually soft-tissue sack that encases the heart. The calcified pericardium is the white arcs that surround the heart in the center of the image. Thankfully, because he's without any symptoms of breathlessness, excessive fatigue, or leg swelling, he won't need to have it surgically corrected. When the pericardium becomes rigid and encircles the heart, it can literally squeeze the heart, a condition called "constrictive pericarditis". The surgery is pretty awful. This man's calcified pericardium likely resulted from one or more viral infections over his lifetime.
Annual physical 26. November 2006 William Davis (0) A judge who lives in my neighborhood was found dead in his bed this week from a heart attack. He was 49 years old. His teenage kids found him and performed CPR, but he was cold and long-gone by then. A close friend of the judge told me that he'd passed an annual physical just weeks before. This sort of tragedy shouldn't happen. It is easily--easily NY Times Jane Brody misses the mark Toggle navigation Home Blog Home Archive Join Now Log in s to niacin, only to observe Lp(a) levels slowly drift back up to the starting level over a period of 2-3 years. In other words, if starting Lp(a) is 200 nmol/l (approximately 80 mg/dl), drops to 70 nmol/l on niacin. Then, over 2-3 years of treatment, it drifts back to 200 nmol/l. Very frustrating. Somehow, your body's Lp(a) manufacturing mechanism circumvents the niacin, sort of like antibiotic resistance (without the bacteria, of course).My response to this, though untested, is to have people take an occasional "niacin vacation". I don't mean take a trip to the Bahamas while on niacin. I mean take 2 weeks off from niacin every three months or so. My hope is that the occasional vacation from niacin will allow the body to continue to respond and suppress "resistance". When resuming niacin, you may have to escalate the dose gradually to avoid re-provoking the "flush".The same "resistance" seems to develop to testosterone in males: an initial drop followed by a gradual increase. Curiously, I've not seen this in females with estrogens, which seems to generate a durable Lp(a) suppressing effect. For this reason, an occasional testosterone "vacation" might also be considered. So far, I've advised several people to try this. The long-term success or failure, however, is uncertain. I know of no other solutions, however. If you have Lp(a) and are on long-term niacin, you should consider talking about this issue with your physician. Like many aspects of Lp(a), while fascinating in its complexity, much remains uncertain. Stay tuned. When LDL is more than meets the eye 18. November 2006 William Davis (0) Jerry wanted to know what to do with his LDL cholesterol of 112 mg/dl. "My doctor said that it's not high but it could be better."So I asked him what the other numbers on his lipid panel showed. He pulled out the results:LDL cholesterol 112 mg/dlHDL 32 mg/dlTriglycerides 159 mg/dlI pointed out to Jerry that, given the low HDL and high triglycerides, his calculated LDL of 112 was likely inaccurate. In fact, if measured, LDL was probably more like 140-180 mg/dl. LDL particles were also virtually guaranteed to be small, since low HDL and small LDL usually go hand-in-hand (though small LDL can still occur with a good HDL). So Jerry's LDL is really much higher than it appears. To prove it, Jerry will require an additional test, preferably one in which LDL is measured, such as LDL particle number (NMR), apoprotein B, or "direct" LDL. It's really quite simple. Jerry likely has a high number of LDL particles that are too small. This pattern confers a three- to six-fold increased risk for heart disease. Treatment requires more than just reducing LDL. Small LDL--an important component of this pattern, responds, for instance, to a reduction in processed carbohydrates like wheat products (breads, breakfast cereals, pretzels, etc.), NOT to a low-fat diet. Weight loss to ideal weight, especially loss of abdominal fat, will yield huge improvements in these numbers. Niacin may be a necessary component of Jerry's treatment program, since it increases LDL size and raises HDL. For more discussion on measures superior to LDL cholesterol, see my upcoming editorial, Let Dr. Friedewald Lie in Peace (an expansion of a previous Heart Scan Blog). It will be posted on the Cardiologist on Call column on the Track Your Plaque website within the next week.) Oil-based vitamin D 14. November 2006 William Davis (2) As time passes, I gain greater and greater respect for the power of restoring vitamin D blood levels to normal, i.e. 50-70 ng/ml. Just yesterday, I saw several people with blood levels of <10 ng/ml--severe deficiency. Vitamin D deficiency this severe poses long-term risk for osteoporosis, arthritis, colon cancer, prostate cancer, inflammatory diseases, diabetes, and heart disease. Vitamin D appears to make coronary plaque reversal--reduction of your heart scan score--easier and faster. But it is important that you take the right kind of vitamin D. Several of the people I saw yesterday with vitamin D levels of somebody living in total darkness were taking vitamin D, but they were taking tablets. Tablets are the wrong form. Powder-based tablets, in my experience, yield little or no rise in blood levels. Some preparations generate a small rise but the dose required is huge. If you're going to take vitamin D, take a preparation that yields genuine and substantial rises in blood levels. This requires an oil-based capsule. I commonly see blood levels of 25-OH-vitamin D3 rise from, say, 10 ng/dl to 60 ng/ml when oil-based capsules are taken.The most common dose I prescribe to patients is 2000 units per day to females, 3000-4000 units per day to males in non-sun exposed months. Ideally, your dose is adjusted to blood levels.The Vitamin Shoppe preparation pictured here is one I've used successfully and generates bona fide rises in blood levels. And it costs around $5. Just be sure the preparation you buy is oil-based. For rapid success, try the "fast" track 14. November 2006 William Davis (1) Have you tried fasting?Before your eyes glaze over, let me tell you what I mean. I don't mean a water-only fast for two weeks while you drool over all the temptations around you and you feel sorry for yourself. I also don't mean the juice fasts that some people use that turn into fruit juice fasts of pure sugar. Here's another way to do it. Usually, 48 hours of doing this will yield several benefits:--Weight loss of 1 lb. You will likely experience an even greater weight loss of 2-4 lbs, but much of this will be water loss. --If you're like me and share a heightened sensitivity to sugars and carbohydrates (like wheat), you may find out just how awful you feel when you eat certain foods. Many people tell me they feel absolutely wonderful when they fast--clearer thinking, increased energy, improved mood. Not the constant gnawing urge to eat they expected. --After your fast is over, you look back and realize just what large portions of food you were eating. You'll be content with smaller quantities--and enjoy it more. The "fast" I've used successfully includes two foods:1) Vegetable juices--that you either juice yourself or purchase. V8 or its equivalent works pretty well. Though purchased V8 is not the best, it's better than nothing and does work reasonably well. If you juice your own vegetable juices, watch out for the diarrhea if you're unaccustomed to vegetable juices. Four 8 oz glasses per day works well. 2) Soy milk--for a source of protein and modest quantity of sugar and fat. I like the Light Silk Soymilk (Vanilla) which contains 80 calories, 2 g fat (0.5 g monounsaturated), 7 g sugar, 6 g protein per 8 oz glass. Four 8 oz glasses of soymilk also work well. In my neighborhood, 8th Continent is another good choice.Sip both of these throughout the day. Of course, drink water in unrestricted amounts. What can you expect in your coronary plaque control/heart scan score reversal program? When the fast is over, a rise in HDL, reduction in small LDL, reduction in triglycerides, reduction in blood sugar and insulin, and a smaller tummy. This strategy can be useful to kick-start weight loss efforts or as a periodic way to maintain control over weight and lipid/lipoprotein patterns.
