Previous studies by Hermsmeyer, et al demonstrated a reduction of coronary reactivity in response to sub-physiological levels of progesterone in non-atherogenic monkeys. In this study, the authors sought to determine if transdermal progesterone cream conferred coronary vascular protection in surgically menopausal pre-atherosclerotic rhesus monkeys. Compared with monkeys receiving placebo cream (n= 5), treated monkeys (n= 7) experienced reduced Lipoprotein (a) levels, and an attenuation of coronary vasoconstriction, which was artificially stimulated by intracoronary serotonin plus U46619. Coronary hyperreactivity is a component of coronary artery disease and was demonstrated in this study to be prevented in pre-atherosclerotic primates by progesterone cream treatment.
