You may have seen one of the many advertisements geared toward men asking if they suffer from "low T" — low testosterone levels that, according to the ads, can result in lost sex drive, diminished energy and moodiness. The answer, they suggest, may be as simple as applying testosterone through a gel or patch.
Now, a new joint study by UCLA, the National Institutes of Health and Consolidated Research Inc., has shown there is a twofold increase in the risk of a heart attack shortly after beginning testosterone therapy among men under 65 who have a history of heart disease. Further, the study confirmed earlier studies that found a twofold increase in heart attack risk shortly after treatment began in men older than 65.
"The extensive and rapidly increasing use of testosterone treatment and the evidence of risk of heart attack underscore the urgency of further large studies of the risks and the benefits of this treatment," Greenland said. "Patients and their physicians should discuss the risk of heart attacks when considering testosterone therapy."
Other authors on the study included William D. Finkle (first author), Gregory K. Ridgeway, John L. Adams and Melissa A. Frasco, of Consolidated Research Inc., and Michael B. Cook, Joseph F. Fraumeni Jr. and Robert N. Hoover, of the NIH. Funding for the study was provided by the NIH.
