Abstract：Objective To analyze the effect of different medical insnrance in Western Liaoning Province on the treatment and short-term prognosis of patients with acute ST segment elevation myocardial infarction (STEMI).Methods A total of 571 patients with STEMI were enrolled in two hospitals in Western Liaoning Province.The patients were divided into self-transport group and ambulance-transport group according to the transportation mode in admission.Clinical data,the onset of symptoms to the first medical contact time (Symptom-to-FMC,STF),intravenous thrombolysis,the proportion of PPCI,major adverse cardiovascular events(MACE) during hospitalization and secondary prevention of medication and the incidence rate of MACE 1 months after discharge were recorded in detail.Results Self-transport group 189 cases (33.1％),ambulance-transport group 382 case (66.9％).The STF time of ambulance-transport group was significantly shorter than that of self-transport group [(12.3±5.3)h vs.(10.2±4.9)h,P＜0.01].The proportion of thrombolysis in the ambulance-transport group was significantly higher than that in the self-transport group(15.3％ vs.7.9％,P=0.006).The proportion of emergency PCI in ambulance group was significantly higher than that in self-transport group (15.9％ vs.9.9％,P=0.040).There was no significant difference in adverse cardiovascular events between the two groups during the period of hospitalization (13.4％ vs.10.6％,P=0.345).The proportion of regular secondary prevention of medication 1 months after discharge significant higher in the ambulance-transport group(60.3％ vs.50.8％,P=0.032).The incidence of MACE was significantly higher in ambulance-transport group than that of ambulance-transport group 1 months after discharge (13.6％ vs.7.9％,P=0.047).Conclusion Emergency vehicle transport can reduce the ischemic time of STEMI patients,reduce the adverse cardiovascular events,and improve the prognosis.
