Clinical outcomes of patients undergoing percutaneous coronary intervention for ST-elevation type and no-ST-elevation type of acute myocardial infarction / 中华急诊医学杂志

ABSTRACT

Objective To evaluate the short-term and long-term outcomes of patients with ST-segment elevation myocardial infarction (STEMI) compared with those with non-STEMI after percutaneous coronary intervention (PCI). Method The DESIRE Ⅱ (Drug-Eluting Stent Impact on Revascularization Ⅱ) was a single-center registered retrospective study of coronary revascularization in our institution between July 2003 and September 2009.Data of demographics, clinical features and revascularization record of STEMI and non-STEMI patients from the DESIRE Ⅱ trial were analyzed. The patients were followed up in OPD or by telephone after discharge. MACCE (major adverse cardiocerebral events) including death, neo-myocardial infarction, stroke and revascularization were recorded. The clinical outcomes of patients of two types were evaluated. Results There were 6005 patients studied with a median follow-up of 566 days. A total of 1009 STEMI and non-STEMI patients were analyzed. The patients with non-STEMI ( n = 206) had higher prevalence of hypertension and history of higher frequency of myocardial infarction as well as revascularization compared with patients with STEMI ( n = 803). The patients with non-STEMI had higher ratio of treatment for multivessel disease (43.7% vs. 34.4%, P = 0.039). There were no significant differences in in-hospital mortality and long-term outcomes (one year survival rate 96% vs. 98%)between patients with STEMI and non-STEMI. The predictors of 1-year mortality were LVEF and blood creatine.Conclusions Despite different chnical features, patients with STEMI and non-STEMI after PCI had similar both short-term and long-term outcomes.
