Analysis for the Cause of Peri-procedural Myocardial Infarction and Risk Factors in Patients After Elective Percutaneous Coronary Intervention / 中国循环杂志

ABSTRACT

Objective: To assess the risk factors for peri-procedural myocardial infarction (PMI) occurrence in patients after percutaneous coronary intervention (PCI) based on the new standard of US Society for cardiovascular angiography and interventions (SCAI). Methods: According to SCAI standard, a total of 3371 relevant patients with 3516 elective PCI in our hospital were enrolled. The baseline clinical features, coronary angiography (CAG) findings and PCI procedural elements were retrospectively studied, the independent risk factors for PMI occurrence were identified by multivariate Logistic regression analysis. Results: There was 108/3516 (3.1%) PMI occurred in all patients. Multivariate Logistic regression analysis presented that age (OR=1.037, 95% CI 1.016-1.058), treating multi-vessel lesions (OR=1.697, 95% CI 1.095-2.629), treating at least 1 bifurcation lesion (OR=1.869, 95% CI 1.213-2.878) and the total length of lesion (OR=1.016, 95%CI 1.009-1.024) were the independent risk factors for PMI occurrence. Conclusions: Age, treating multi-vessel lesions, at least one bifurcation lesion and the total length of lesion were the independent risk factors for PMI occurrence in patients after elective PCI.
