Comparison of baseline data, initial course, and management:: Losartan versus captopril following acute myocardial infarction (The OPTIMAAL trial)

The OPTIMAAL study was a multicenter, double-blind, randomized, parallel, trial in high-risk patients who were treated early after acute myocardial infarction that compared treatment with an angiotensin-converting enzyme inhibitor (captopril) and a selective angiotensin II antagonist (losartan) on survival and morbidity. A total of 5,477 patients with heart failure during the acute phase or with a new Q-wave anterior infarction or reinfarction were recruited. This study describes the baseline data and initial course of the cohort and compares these data and patient management across countries.
