Postmenopausal estrogen therapy is associated with a reduced risk of coronary heart disease in prospective observational studies.

If you are postmenopausal, this study suggests that estrogen therapy might lower your risk of heart disease. However, this is an observational study, so other factors might be involved. Consult your doctor to weigh the benefits against potential risks like breast cancer or blood clots, as individual health profiles vary significantly.
