*Postmenopausal women with higher levels of male sex hormones levels have greater prevalence of coronary artery disease. (Embargoed until 4:45 p.m. Central Time (5:45 p.m. ET), Tuesday, November 15) The relationship between male sex hormones called androgens and atherosclerosis in women is poorly understood. Some studies have found an increased risk of coronary artery disease in women who have high levels of androgen, such as those who have polycystic ovary syndrome. Scientists with the Women's Ischemia Syndrome Evaluation (WISE) study analyzed blood hormone levels of 400 women (296 postmenopausal and 104 premenopausal) undergoing coronary angiography for suspected myocardial ischemia, a heart condition characterized by reduced blood flow. Hormones measured included estradiol, estrone, FSH, LH, free testosterone, sex-hormone binding globulin, androstenedione, and DHEA-S. Glucose and insulin were also measured. The investigators found that among postmenopausal women, higher levels of free testosterone and androstenedione are associated with greater coronary artery disease as sh
