[Estrogen receptors and vascular aging].

Area of Science:

• Cardiovascular Science
• Endocrinology
• Women's Health

Background:

• Cardiovascular disease (CVD) incidence is lower in premenopausal women but increases post-menopause.
• Estrogen's protective effects on the arterial endothelium are well-documented in preclinical studies.
• Past clinical trials yielded mixed results on estrogen's cardiovascular benefits in aging women.

Purpose of the Study:

• To review clinical and experimental data on estrogen's effects on cardiovascular disease (CVD).
• To focus on estrogen's impact on endothelial function and arterial protection during aging.
• To explore novel estrogen receptor (ER) mechanisms for optimizing hormone therapy in menopause.

Main Methods:

• Literature review of preclinical and clinical studies on estrogens and CVD.
• Analysis of estrogen receptor (ER) expression and signaling in arteries.
• Examination of recent research on ER alpha (ERa) mechanisms of action.

Main Results:

• Estrogens demonstrate protective effects on the arterial endothelium.
• Estrogen receptor (ER) abnormalities are observed in arteries with aging.
• Emerging evidence highlights ERa's role in arterial protection.

Conclusions:

• Estrogen therapy holds potential for improving cardiovascular health in menopausal women.
• Understanding ER signaling is crucial for developing effective hormone therapies.
• Optimizing hormone therapy based on ER mechanisms may mitigate CVD risk in aging women.
