Abstract:
Objective: To explore the application and affecting factors of clopidogrel loading therapy in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) in china in 2006 and 2011. Methods: Based on “China patient-centered evaluative assessment of cardiac events retrospective study of acute myocardial infarction”, we collected clinical information of STEMI patients with PCI in 2006, 2011 and analyzed clopidogrel loading therapy status in different years and different hospitals. According to clopidogrel doses, the patients were divided into 2 groups: Clopidogrel 300mg group, the patients received a single dose of clopidogrel ≥300mg while <450mg and Clopidogrel 600mg group, the patients received a single dose of clopidogrel ≥450mg while ≤600mg. The relevant factors affecting clopidogrel loading therapy status were identiifed by binary Logistic regression analysis. Results: A total of 2481 eligible patients were enrolled and their mean age was (60.9 ± 12.0) years including 21.4%female. From 2006 to 2011, the overall application of clopidogrel loading was (51.0% vs 47.4%), the ratio for patients in Clopidogrel 300mg group was (43.1% vs 39.2%), in Clopidogrel 600mg group was (7.8% vs 8.2%), allP>0.05. In 2006, the hospital median rate of clopidogerl application was 44.4% (IQR 21.8% to 69.0%) and in 2011, it was 48.1% (IQR 25.0% to 70.8%),P=0.940. Binary logistic regression analysis showed that the patients were admitted within 12 hours of onset, with primary PCI and treated in central region had the higher rates of clopidogrel loading therapy. Conclusion: Clopidogrel loading therapy was seriously inadequate in STEMI patients with PCI, variation was across hospitals and the status was similar between 2006 and 2011. Clopidogrel loading therapy should be improved.
