Cardiovascular disease and ovarian function.

摘要

PURPOSE OF REVIEW: Coronary heart disease (CHD) is the leading cause of death in the aging female population in the developed world. Ovarian endocrinology plays an important role in modulating a woman's CHD risk. We herein present an overview of our current understanding of CHD risk profile in the context of ovarian physiology and senescence. RECENT FINDINGS: Endogenous ovarian estrogen has long been recognized to offer cardiac benefit and vascular protection against atherosclerosis. Existing data, however, do not allow for an extrapolation of the recognized cardioprotective implications of the reproductive-age endogenous estrogenic milieu to the use of exogenous estrogen in postmenopausal women. Ongoing efforts are targeting the concept that when reintroduced proximate to onset of ovarian senescence, exogenous estrogen may retard the process of atherogenesis. Until this hypothesis is substantiated, cardioprotection must not be an indication for initiating hormone therapy in menopausal women. SUMMARY: Ovarian hormones modulate the processes of atherosclerosis and the mechanisms underlying CHD. The female reproductive hormones offer a cardioprotective milieu that is rapidly attenuated with the cessation of ovarian function (be it following natural menopause or after medical or surgical ovarian extirpation). The role of exogenous hormone therapy, and the nuances of timing and duration of exposure, are still being elucidated.
