Clopidogrel and ASA dose before PCI

In this large trial of patients with acute coronary syndrome undergoing PCI, they were randomized to high or low dose ASA (325mg vs 81mg) and high or low clopidogrel (600mg, followed by 150mg for a week, then 75mg/day, versus 300mg, followed by 75mg/day). The high dose clopidogrel group had lower 30 day CV death/MI/stroke (3.9% vs 4.5%), but ASA dose did not affect the primary outcome. High dose clopidogrel did increase the risk of major bleeding (1.6% vs 1.1%) (abstract)
