The aim of this study was to evaluate the clinical impact resistance thienopyridines through genetic analysis of CYP2C19 receptor. The primary endpoint was a combination of mortality, myocardial infarction, stent thrombosis in the resistance group (few responders) versus non-resistant (responders) to the thienopyridines. 1445 patients were included of which 22% were considered few responders. There was no difference in the primary endpoint between responders and nonresponders (3% for both groups, P = .83).
