Q: Question: Is long-term estrogen replacement therapy associated with improved exercise capacity in postmenopausal women without known coronary artery disease?
Answer: Estrogen replacement therapy is associated with increased exercise capacity as measured by MVO (2) and anaerobic threshold in postmenopausal women without coronary artery disease. This finding is consistent with the beneficial effect of short-term estrogen administration on improved endothelium-dependent and endothelium-independent vasodilation.
A:
yes
