Abstract: Objective To analyze the influencing factors of antiplatelet drug clopidogrel resistance in patients with acute coronary syndrome, so as to help clinicians quickly identify patients who may be resistant to antiplatelet therapy. Methods This study included patients with acute coronary syndrome who received coronary intervention and on dual antiplatelet at Fuwai Hospital throughout 2013. According to the results of thromboelastography (the result recorded as ADP-induced platelet-fibrin clot strength, MAADP,) the selected patients were divided into resistance group (MAADP>47 mm) and non-resistance group (MAADP≤47 mm). Via clinical data, univariate and multivariate logistic regression analysis were used to screen out influencing factors independently related to clopidogrel treatment resistance. Results A total of 2 511 patients were enrolled in the study, among them 781(31.10%) patients had clopidogrel treatment resistance. After univariate and further multivariate logistic regression analysis, five clinical factors were screened to be independently associated with resistance to antiplatelet therapy, namely reduced renal function (OR=3.08, 95%CI:1.28-7.36); female (OR=2.86, 95%CI:2.26-3.61); diabetes mellitus (OR=1.61, 95%CI:1.33-1.95); elevated platelet count (OR=1.55, 95%CI:1.07-2.25) and proton pump inhibitor use (OR=1.25, 95%CI:1.02-1.54). Conclusion Reduced renal function, female, diabetes, elevated platelet count and the use of proton pump inhibitors are the independent influencing factors of antiplatelet drug clopidogrel resistance in patients with acute coronary syndrome, which need to be paid attention in the clinical treatment, thereby guiding individualized antiplatelet therapy.
