Abstract：Objective To investigate the influence factors of prehospital delay of acute ST-segment elevation myocardial infarction(STEMI) in poor areas of northern Liaoning Province.Methods Totally 635 cases of acute STEMI in 7 county hospitals in poor areas of northern Liaoning Province were included in this study,and the patients were divided into 3 groups according to the symptom onset to first medical contact time(S2T):S2T ＜ 3 h group,S2T 3-12 h group and S2T ＞ 12 h group.Demographic and clinical features,environmental factors,behavioral factors and in-hospital adverse cardiovascular events were analyzed.Results There were 125 cases(19.7％) in S2T ＜3 h group,120 cases(18.9％) in S2T 3-12 h group and 390 cases(61.4％) in S2T ＞ 12 h group.Mean S2T[(2.7 ± 1.2),(10.9 ±2.6),(24.3 ±6.4)h] and mean age[(56 ±6),(59 ±6),(64 ± 9) years] had significant differences among 3 groups (all P ＜ 0.01).Incidences of patients having health insurance,below primary school education,typical symptoms,awareness of the heart disease,concerns of hospitalization expenses,not calling 120 and nocturnal infarction attack had significant differences among 3 groups(P ＜0.05).Multivariate logistic regression analysis showed that age≥65 years,education degree below primary school,atypical symptoms,concerns of hospitalization cost and not calling 120 were independent predictors of prehospital treatment delay (all P ＜ 0.05).The incidence rate of adverse cardiovascular events in the patients in S2T ＜ 3 h group was significantly lower than that in S2T 3-12 h group and S2T ＞ 12 h group (all P ＜ 0.05).Conclusions There is an extremely high prevalence of prehospital delay of acute STEMI in poor areas of northern Liaoning due to the lack of awareness of first aid for acute myocardial infarction.It is urgent to improve the emergency rescue ability and optimize the three-classdiagnosis and treatment process.
