Anabolic Steroids May Weaken the HeartI had a chance earlier today to visit with the production crew from Mississippi Public Broadcasting. The authors noted that testosterone replacement therapy was often prescribed without an established diagnosis of low testosterone levels hypogonadism. The history of anabolic steroids dates to the mids when the chemical structure of the male sex atacks testosterone was elucidated. Soon afterward, xttacks synthesis anabolic steroids cause heart attacks testosterone was possible in anabolic steroids cause heart attacks laboratory. The group of medications that we call anabolic steroids are synthetic derivatives of testosterone.

The results have implications for athletes who take anabolic steroids to enhance performance, says principal investigator Carl Grunfeld, MD, PhD, chief of the metabolism and endocrine sections at the San Francisco VA Medical Center.
The researchers found that as expected, anabolic steroids lead to gains in both lean body mass and fat in men with HIV wasting. The randomized, double-blind trial among HIV-positive men was the largest study of its type on men with HIV-associated weight loss, according to the study authors. For the first 12 weeks of the trial, the men were randomly assigned to receive daily doses of either 20, 40, or 80 milligrams of the anabolic steroid oxandrolone or a placebo.
They were allowed to receive open-label oxandrolone for the second week period. Grunfeld says the adverse effects of the steroids were clear-cut within the first 12 weeks. This predisposes people to an increased risk of heart attack. Furthermore, we found grade III and grade IV liver toxicity in some men, which means a very significant risk of serious liver damage. These effects were not seen in men taking placebo, according to Grunfeld.
The researchers observed that in men with the most wasting, the 20 milligram dose was more effective than higher doses in promoting weight gain. Subjects who weighed more and were healthier - and were therefore more like athletes who use the drugs, observes Grunfeld - required higher doses to gain weight.
Based on observed changes in HDL and LDL, Grunfeld estimates that heart attack risk would be increased 58 percent among men taking 20 milligrams of oxandrolone per day, two-fold with a 40 milligram daily dose, and three-fold with 80 milligrams.
The ability to promote gains in both muscle and fat makes these drugs unique among the medications used for HIV wasting disease, notes Grunfeld.
He says that among patients with serious wasting illnesses, the benefits of immediate weight gain could still potentially outweigh the risks of longer-term heart and liver damage.
The more fat you have, the less muscle you burn. Grunfeld, who has no further plans to study steroids, says he would like to see the current study validated in two future studies by other investigators. Co-authors of the paper were Donald P. Kotler, MD, of St. The research was supported by a grant from Biotechnology General, Inc.
