Subclinical atherosclerosis will be evaluated in 728 women (305 African American, 423 Caucasian) enrolled in the Pittsburgh and Chicago sites of the Study of Women's Health Across the Nation (SWAN), a multicenter study characterizing the biological and psychosocial antecedents and sequellae of menopause. The extent to which diminishing ovarian function affects vascular function and accelerates the development of atherosclerosis in the coronary arteries, aorta and carotid arteries will be evaluated. Serial measures of coronary and aortic calcification (by EBCT), carotid atherosclerosis, endothelial function and aortic stiffening will be performed two years apart. The prevalence and progression of subclinical atherosclerosis will be evaluated in relation to serial measures of ovarian function, psychosocial and behavioral factors, markers of clotting and inflammation as well as traditional cardiovascular risk factors, all collected in SWAN. Decreased ovarian function and premenopausal obesity are likely the primary determinants of early coronary atherosclerosis as measured by calcification on EBCT. Aortic calcification occurs earlier than coronary calcification, may predict coronary calcification, and is expected to be the best marker of risk associated with traditional factors in these younger women. Preliminary data indicate that changes in coronary and aortic calcification can be observed over short periods of time in these women. A period of diminishing estrogen levels is the optimum time to observe changes in endothelial function which likely precede measurable atherosclerosis and thus may be the earliest markers for disease potential. Vascular stiffness, a marker for the biologic aging of the vascular system, is highly correlated with measures of insulin sensitivity which is altered in women at mid-life in conjunction with increases in central adiposity. Racial differences in disease prevalence and the relative importance of certain risk factors are likely. The investigators state that in summary, this application will allow a detailed elucidation of how diminishing ovarian function affects cardiovascular disease, which can only be done within the context of a careful prospective study of the menopausal transition such as SWAN.
