Abstract:
Objective To assess the prevalence and risk factors associated with clopidogrel resistance in patients with acute myocardial infarction after primary PCI(percutaneous coronary intervention). Methods Using a retrospective case?control study,210 patients with acute myocardial in?farction who underwent primary PCI in the first hospital affiliated to China Medical University between October 2013 and September 2014 were re?viewed. Patients were divided into the normal group and the resistance group according to the platelet aggregation rate(PAR),and the incidence of clopidogrel resistance was calculated and the correlation between age,gender,smoking,alcohol drinking,blood pressure,blood lipid,glycosylated hemoglobin,and the clopidogrel resistance were analyzed. Results The incidence of clopidogrel resistance in patients underwent primary PCI was 36.67%. Platelet aggregation rates were 62.62 ± 9.23%and 32.71 ± 11.77%respectively in two groups(P<0.001). Multivariate logistic regression analysis found that clopidogrel resistance was positively correlated to high level of glycosylated hemoglobin(P=0.037,OR 1.241,95%CI 1.013?1.519). Conclusion High level of glycosylated hemoglobin was the independent risk factor of clopidogrel resistance. The risk of clopidogrel resis?tance will significantly increase in these diabetic patients who cannot control blood sugar well.
