After years of studying cardiovascular diseases (CVD) in men due to their higher incidence compared to women, attention is now being paid to female CVD and their pathophysiology. Even though premenopausal women have a lower incidence of CVD, this disparity progressively diminishes after menopause, highlighting the key role of sex hormones. Many preclinical and fundamental studies have demonstrated protective effects of estrogens on arterial endothelium, suggesting that hormone therapy could improve cardiovascular health in menopausal women. However, disappointing outcomes from a major clinical trial two decades ago questioned the cardiovascular protection by estrogens with age. In this review, we will summarize the main clinical and experimental studies reporting the effects of estrogens on CVD, with a focus on their impact on endothelial function. Then, we will present abnormalities in the expression and signaling of estrogen receptors (ERs) in the arteries, and the contribution of conventional estrogens to arterial protection during aging. Finally, we will examine how recent advances in the mechanisms of action of ERa could help to optimize hormone therapy for menopause.
