ABSTRACT
Objective:
To explore the clinical characteristics of ST elevation and non-ST elevation acute myocardial infarction (AMI) related with left circumflex artery (LCX) occlusion.Methods:
Clinical data of 86 consecutively enrolled patients with LCX occlusion -related AMI undergoing percutaneous coronary intervention (PCI) were retrospectively analyzed. According to manifestations of electrocardiography, the patients were divided into ST elevation myocardial infarction (STEMI) group (n=32) and non STEMI (NSTEMI) group (n=54). Clinical features and prognosis were compared between two groups.Results:
Compared with NSTEMI group, there were significant increase in serum level of creatinine [(80±23) μmmol/L vs. (100±30) μmmol/L], in rates of intra-aortic balloon counterpulsation (IABP)support (3.7% vs. 18.8%), usage of invasive respiratory machine (1.9% vs. 15.6%), ischemic mitral reflux (13.0% vs. 40.6%), complete atrioventricular block (0 vs. 9.4%), proportion of left coronary artery dominant type (7.4% vs. 28.1%) and left ventricular end-diastolic diameter [LVEDd,(46±4)mm vs.(48±5)mm?]; And significant decrease in percentage of triple-vessel coronary disease (72.2% vs. 46.9%) in STEMI group, P0.05) between STEMI group and NSTEMI group.Conclusions:
Compared with patients with NSTEMI, patients with STEMI have poorer heart function in patients with left circumflex artery occlusion, which may be related to more left coronary dominance.
