AIM: The purpose of this study was to assess associations between distinct patterns of circulating estradiol (E2) and follicle-stimulating hormone (FSH) over the menopause transition (MT) and subclinical measures of atherosclerosis after menopause. METHODS AND RESULTS: Four temporal patterns of E2 decline (Low: low before and after final menstrual period (FMP); Medium: medium before and high after FMP; High-early decline: high prior to FMP and early decline thereafter; High-late decline: high prior to FMP and late decline thereafter) and three of FSH rise (Low, Medium, High) over 9.6 years across FMP were identified and linked to carotid intima-media-thickness (IMT), adventitial diameter (AD), and presence of carotid plaque (cPlaque) measured after menopause at the 12th annual visit (visit 12). Participants were 856 women (age at visit 12 = 59.5 ± 2.7 years) from the Study of Women's Health Across the Nation (SWAN), who never reported a stroke or a heart attack. In models adjusted for visit 12 or baseline cardiovascular disease (CVD) risk factors, odds of having any cPlaque were ∼43% lower among women with the High-early decline E2 trajectory compared to women with the Low E2 trajectory. In contrast, women with the Medium E2 trajectory had significantly higher IMT than those with the Low E2 trajectory adjusting for visit 12 CVD risk factors. Interestingly, adjusting for baseline CVD risk factors attenuated this association. The Low FSH group had lower IMT than the Medium and High FSH groups (p ≤ 0.05) in all models. CONCLUSION: During MT, women are subjected to hormonal alterations that could potentially increase their risk of developing CVD after menopause.
