Low dose estrogens inhibit coronary artery atherosclerosis in postmenopausal monkeys

Low dose CEE (0.30 mg/woman/day equivalent) was effective in reducing coronary atherosclerosis and the magnitude of the protection was comparable to previously reported studies using doses equivalent to 0.625 mg/woman/day. This study provides an experimental basis for the assumption that low dose CEE may be as effective as the traditional dose in inhibiting coronary atherosclerosis progression in early postmenopausal subjects.
