A recent study of 121 clinical trials on cardiovascular disease by the National Heart, Lung and Blood Institute shows that men continue to be the focus for much of the research on heart disease. The study, which evaluates trials completed over a 33 year time period, indicates that women were just 38 percent of participants in mixed sex studies. Researchers concluded that much of the studies concentrated on heart disease problems known to affect men with more frequency, like coronary artery disease. In a series of six studies on congestive heart failure, a disease that affects women, females comprised only 26 percent of the total participants. The study displays that the federal governments’ 15-year push to enroll more women in heart studies has had minimal success, as women remain grossly underrepresented in heart disease research.
