...ALCOHOL. One or two drinks a day seem to cut by one-third the risk of developing clogged arteries in the legs--a pain-ful, sometimes dangerous condition that tends to afflict the elderly. Alcohol probably helps legs the same way it helps the heart--by raising good hdl cholesterol...
...developed premature heart disease--a result comparable to that for men with total cholesterol counts in the danger zone of 240 mg/dL. Blood tests revealed one important reason: as long as the subjects had high levels of Lp(a), it didn't matter if they had normal levels of HDL, the so-called good cholesterol, and LDL, the so-called bad cholesterol...
...including the famous Nurses Health Study that followed 120,000 nurses for more than 10 years, have found that postmenopausal women on estrogen have about half the incidence of heart disease of those who don't take hormones. HRT seems to improve a woman's ratio of good cholesterol (HDL) to bad cholesterol (LDL) and also maintains the pliability of the blood vessels, lessening the risk of blockage...
Similarly, researchers studying estrogen and heart disease see the greatest benefits in long-term use. Estrogen helps keep levels of LDL cholesterol low and HDL cholesterol high, which is one reason pre-menopausal women have a much lower rate of heart disease than their male peers. Without HRT, a woman's risk of a heart attack rises to match that of men within 15 years of menopause. Estrogen also acts directly on blood vessels, causing them to dilate slightly so that blood flow improves, says Dr. Roger Blumenthal of Johns Hopkins Hospital. But these benefits disappear as soon...
NOTHING IS EVER SIMPLE WHEN IT COMES TO THE heart. First the big worry was a high cholesterol level. Then, it was discovered, cholesterol comes in two varieties, and the real question was whether one had more of the good type, HDL, rather than the bad kind, LDL. Now it appears that HDL itself contains a mix of both good and bad elements. What may really count in the development of heart disease, according to scientists at a meeting of the American Heart Association, is the amount of the HDL component, LpA-I. The more of this protective protein...
