Abstract
The postmenopausal increase in the incidence of coronary artery disease implied a protective effect of estrogens. Nonrandomized, clinical and experimental studies have supported this notion. In the first randomized study (HERS 1998) no protective effect on prognosis of postmenopausal women with coronary artery disease was demonstrated. Also, in healthy postmenopausal women no beneficial effect of a hormone-replacement therapy on coronary events was shown (WHI-Study 2002, 2004). Therefore, hormone-replacement therapy is not recommended for prophylaxis of cardiovascular disease in healthy women or in women with documented coronary artery disease (Recommendation class I, evidence-level A). The continuation or the start of a hormone- replacement therapy is only justified for therapy of severe menopausal symptoms. Women should be informed that changes in lifestyle including not smoking, a heart healthy diet, and regular exercise are the most important measures to prevent cardiovascular diseases.
