Abstract Objective To promote standardized treatment of acute ST segment elevation myocardial infarction (STEMI) by retrospectively analyzing treatment and short- and long- term prognosis of patients with STELMI. Methods 190 patients with STEMI were enrol ed and divided into immediate reperfusion group(n=45) and delayed reperfusion group (n=111) based on whether received effective immediate reperfusion therapy. The time from symptom onset to admission, transfer rate and time, the percentage of emergency PCI, in- hospital mortality and incidence of heart failure, echocardiographic results within 1 week and 1 year later after myocardial infarction were surveyed. Results The median time from symptom onset to admission was 5 hours, the transfer rate was 61.1%, the transfer time was 1 hour to the first level hospital and 3 hours to the second level hospital, the percentage of emergency PCI was 21.6%, the ratio of intravenous thrombolysis was 5.8%, the in- hospital mortality was 6.3%, the incidence of the heart failure was 40%. Left ventricular ejection fraction, left ventricular end diastolic diameter and systolic diameter were similar between immediate and delayed reperfusion groups within 1 week, but the later two parameters were significantly less in immediate reperfusion group than in delayed reperfusion group after one year(al P<0.05). Conclusion The treatment conditions of STEMI in Ningbo region is unsatisfactory, with higher in- hospital mortality and heart failure incidence, which should be improved strongly.
