Some benefit from antioxidant vitamins on the risk of cardiovascular disease

About 23% or 62 million Americans have some form of cardiovascular disease (CVD; eg, heart disease, stroke, atherosclerosis, coronary heart disease, angina, coronary artery disease, high blood pressure, or heart failure).

The Women’s Antioxidant Cardiovascular Study concluded, “There were no overall effects of ascorbic acid [vitamin C], vitamin E, or beta carotene on cardiovascular events among women at high risk for CVD.”

But read on to see those who did benefit. Continue reading Some benefit from antioxidant vitamins on the risk of cardiovascular disease →

Experts respond to the negative AHRQ report on meditation

The report by the University of Alberta Evidence-based Practice Center (UAEPC) after reviewing the published literature on meditation practices for health were published here and discussed here.

The authors found so many flaws in the design of the studies that “conclusions on the effects of meditation practices in healthcare cannot be drawn based on the available evidence.” The report was funded by the NIH Agency for Healthcare Research and Quality (AHRQ).

Cognitive behavioral therapy used to improve treatment of sleep apnea

Sleep apnea occurs when people fail to breath while sleeping. Untreated, it can cause high blood pressure and other cardiovascular disease, memory problems, weight gain, impotency, and headaches.

Continuous positive pressure breathing (CPAP) is effective treatment. But it’s uncomfortable to use (photo).

Now, a study shows that cognitive behavioral therapy (CBT) improves acceptance of CPAP. Continue reading Cognitive behavioral therapy used to improve treatment of sleep apnea →

Transplant patients are cautioned about taking Schisandra

Schisandra sphenanthera (Nan Wu Wei Zi, lemon-wood) is “commonly used in Chinese herbalism, where it is considered to be one of the 50 fundamental herbs.” I found no clinical study in humans to support the many claims for this Chinese herbal medicine.

Now, there’s a report of a drug interaction with tacrolimus (Prograf) — a drug used to suppress the immune system in order to prevent organ rejection of liver, kidney, or heart transplants. Continue reading Transplant patients are cautioned about taking Schisandra →

TM for patients with CHF

Transcendental Meditation is a frequent source of heated debate. Just check out the entry on Wikipedia. It’s a positive read except that much of it is contested. Such is the risk of the “free encyclopedia.” Robert Todd Carroll has a more skeptical view of TM.

Anyway, with that in mind, here’s a study of the effectiveness of transcendental meditation on functional capacity and quality of life of African Americans with congestive heart failure.

Measuring the effect of folic acid on homocysteine and the risk of heart disease

High blood levels of the amino acid called homocysteine are thought to increase the risk for heart disease by damaging the lining of blood vessels and increasing blood clotting.

Despite this, the American Heart Association doesn’t recommend widespread use of folic acid to lower homocysteine blood levels.

Does this make sense?

Here’s the latest information.
