We evaluated the effect and optimal dose of clopidogrel pretreatment in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention (PPCI). The study included 383 consecutive patients with ST-elevation myocardial infarction who had undergone PPCI and were prospectively followed up for a prespecified primary end point of recurrent acute coronary syndrome, stent thrombosis, congestive heart failure, and/or death at 30 days. Of these patients, 217 (57%) received clopidogrel loading before and 166 (43%) after PPCI. A similar number received low (300 mg) and high (600 mg) clopidogrel doses before and after PPCI. Clopidogrel loading before, compared with after, PPCI…
