Hormone replacement therapy use is associated with a lower occurrence of carotid atherosclerotic plaques but not with intima-media thickness progression among postmenopausal women. The vascular aging (EVA) study.

Abstract : BACKGROUND: Information on the impact of hormone replacement therapy (HRT) on carotid atherosclerosis is limited. Moreover, transdermal estrogens have not been investigated. METHODS: We examined association of HRT use with ultrasonographically assessed carotid atherosclerotic plaque occurrence and mean common carotid artery intima-media thickness (CCA-IMT) progression. Within the Vascular Aging (EVA) Study, a community-based cohort, 815 postmenopausal women aged 59-71 have been followed during 4 years. Among these women, 166 had already used HRT. RESULTS: Women who had ever used HRT experienced a lower occurrence of plaques (8.6 versus 19.1%, P=0.003). After adjustment for the main cardiovascular risk factors, odds-ratio for plaque occurrence was 0.41 (95% confidence interval 0.21-0.78, P=0.01) among ever users of HRT compared with never users. When transdermal route of estrogen administration was used, adjusted odds-ratio was 0.66 (95% confidence interval 0.47-0.99, P=0.04). The progression of IMT, which was measured at a plaque-free site and adjusted on initial levels of CCA-IMT did not differ between ever and never users of HRT. It was 0.011 mm per year among ever users and 0.012 mm per year among never users (P=0.61). CONCLUSION: These data suggest that HRT use may prevent the development of atherosclerotic plaques in postmenopausal women, especially when estrogens are administered by transdermal route.
