Association of CYP2C19 Polymorphism with Clopidogrel Resistance in Patients with Acute Coronary Syndrome in China.

ABSTRACT: BACKGROUND The relationship between clopidogrel-resistance (CR) and polymorphism located in genes encoding clopidogrel metabolism-related enzymes has not been fully explored. Thus far, few studies on CR-associated polymorphism have been conducted in the Chinese population. The purpose of this study was to identify CYP2C19 polymorphism associated with CR in patients with acute coronary syndrome in China. MATERIAL AND METHODS There were 125 patients with acute coronary syndromes (ACS) selected for this study. Of these, 27 patients (21.6%) showed CR (less than 10% reduction in platelet accumulation rate), while the remaining 98 patients (78.4%) were non-clopidogrel-resistant (NCR). RESULTS There were significant differences in the allele frequencies of CYP2C19 (rs4244285) (P=0.03) and CYP2C19
