Estrogens and progestins in postmenopausal women: influence on lipid parameters and cardiovascular risk.
Postmenopausal women are 2-3 times more likely to have a heart attack than premenopausal women. According to the results of the Framingham study, angina is one of the main manifestations of coronary heart disease in women, whereas myocardial infarction and sudden death are more frequent in men. Cigarette smoking, high blood pressure and hypercholesterolemia are major risk factors for coronary heart disease in both men and women, while diabetes mellitus and hypo-high-density lipoproteinemia are more clearly associated with cardiovascular disease in women than in men. Endogenous and exogenous hormones may be a major determinant of the cardiovascular risk in women. Premenopausal women have a considerably lower incidence of coronary heart disease than postmenopausal women, and estrogen therapy is associated with a reduced risk in the latter. Part of this protective effect seems to be due to the influence of estrogen therapy on lipoprotein metabolism, i.e. a decrease in LDL cholesterol and an increase in HDL cholesterol. Progestins, to an extent which depends on their androgenic potency, have the opposite effects. A large study (the Postmenpausal Estrogen Progestin Intervention Trial) has been launched to test the effect of the estrogen-progestin combination on various cardiovascular risk factors.
