Hormone Replacement Therapy and Cardiovascular Health in Postmenopausal Women

Area of Science:

• Cardiovascular Biology
• Endocrinology
• Sex Differences in Medicine

Background:

• Cardiovascular disease (CVD) prevalence differs by sex, with men and postmenopausal women at higher risk than premenopausal women.
• Sex hormones, particularly estrogen (E2), exert protective cardiovascular effects through genomic and non-genomic actions on vascular cells.
• Menopausal hormone therapy (MHT) investigations for CVD have yielded inconsistent results, influenced by numerous factors.

Purpose of the Study:

• To explore the complex role of sex hormones in cardiovascular function and disease.
• To investigate the variable outcomes of menopausal hormone therapy (MHT) in cardiovascular health.
• To highlight the need for gender-specific approaches in managing cardiovascular disease.

Main Methods:

• Review of existing literature on sex hormones, estrogen receptors (ERs), and cardiovascular effects.
• Analysis of factors influencing MHT efficacy and outcomes.
• Examination of sex hormone influences in diverse populations, including athletes and transgender individuals.

Main Results:

• Estrogen (E2) demonstrates protective cardiovascular effects via interactions with estrogen receptors (ERs).
• MHT efficacy in CVD is complicated by preparation, ER status, menopausal stage, and hormonal milieu.
• Sex hormones influence cardiovascular health across various populations and therapeutic contexts.

Conclusions:

• Sex hormones play a critical role in cardiovascular health and disease development.
• Further research into sex hormone and receptor interactions is vital for understanding sex differences in vascular signaling.
• Tailored, gender-specific strategies are needed for effective cardiovascular disease management, particularly for postmenopausal women.
