Brief summary

The purpose of the study is to determine whether hormone replacement therapy in post menopausal women with coronary artery disease prevents future heart attacks or death from coronary heart disease.

Detailed description

A randomized, blinded trial in post menopausal women with cornaornary artery disease to test the hypothesis, among 2340 women who have a uterus, that those randomized to receive estrogen-progestin replacement therapy (Premanrin .625 mg daily plus medroxygrprogesterone acetate 2.5 mg daily) have the same frequency on new CHD events (myocardial infarction and CHD death) as those randomized to placebo.

Interventions
