About this study
To evaluate subclinical atherosclerotic disease in menopausal women.
Read the detailed description
BACKGROUND:
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.
DESIGN NARRATIVE:
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 electron beam computed tomography [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. The study is conducted jointly by Dr. Lynda Powell (R01HL65581) at Rush-Presbyterian-St. Luke's Medical Center in Chicago and Dr. Kim Tyrrell (R01HL65591) at the University of Pittsburgh.

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2014; AzTrials last refreshed its copy on 7 Nov 2026.
