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

description | 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/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 (rs4986893) (P=0.005) between the 2 groups; however, there was no significant difference in allele frequencies of ABCB1 (rs1045642) (P=0.661) and PON1 (rs662) (P=0.690) between the 2 groups. The null allele in the CYP2C19 (rs4244285) [odds ratio (OR)=5.317, 95% confidence interval (CI) 1.542–26.428, P=0.001] and CYP2C19 (rs4986893) (OR=4.295, 95%CI 1.312–17.517, P=0.013) is one of the causes of CR in patients with ACS in China. CONCLUSIONS: The CYP2C19 polymorphism (rs4244285 and rs4986893) is the correlative factor of CR in patients with ACS in China. It was found that the null allele in the CYP2C19 polymorphism was related to the higher CR risk. According to the key role of CYP2C19 in the clopidogrel activation and the evaluated role of CYP2C19 in this study, further studies should be carried out to formulate therapeutic alternative methods for CR in patients with ACS. |
