Abstract:
Objective To explore the predictive factors of side branch occlusion in patients with ST-segment elevation myocardial infarction by coronary angiography. Methods A total of 1223 patients with acute ST segment elevation myocardial infarction undergoing primary percutaneous coronary intervention were consecutively enrolled in Fuwai hospital from January 2014 to December 2015. According to the coronary angiography there were 256 patients with bifurcation in the culprit lesions. Demographic data, past medical history and coronary angiography characteristics were collected in all patients. Results Among the 256 patients, there were 33 patients with branch occlusion and 223 patients without branch occlusion. Multivariate analysis demonstrated that severe stenosis of side branch ostium odds ratio 1.06, 95% confi dence interval 1.03-1.09,P < 0.001) and thrombus in side branch ostium (odds ratio 5.43, 95% confidence interval 1.23-23.93, P=0.025) were independent risk factors for predicting branch occlusion. Conclusions Side branch occlusion in culprit lesions of patients with ST-segment elevation myocardial infarction is related to the severity of branch ostium stenosis and thrombosis in branch ostium.
