Abstract：Objective To investigate the impact of the chest pain center"city-wide model"on treatment ef-ficiency and clinical outcomes in patients with acute ST-segment elevation myocardial infarction(STEMI).Meth-ods A retrospective cohort study was conducted using data from STEMI patients admitted to Longyan First Hospi-tal between January 2021 and December 2023.Patients were divided into three groups based on the implementation phase of the"city-wide model":Group A(pre-establishment phase,n=325),Group B(early establishment phase,n=322),and Group C(mature phase,n=340).Efficiency metrics,including door-in-door-out time(DIDO),first med-ical contact-to-wire time(FMC2W),door-to-wire time(D2W),and catheterization laboratory activation time,were compared among the groups.Additionally,the rates of emergency department and CCU bypass,reperfusion,in-hos-pital mortality,and complications(heart failure,bleeding,reinfarction)were analyzed.Results Compared with Groups A and B,Group C showed significant reductions in DIDO,FMC2W,D2W,and catheterization laboratory activation time(P＜0.05).The rates of emergency department and CCU bypass,FMC2W compliance,D2W com-pliance,and reperfusion were significantly higher in Group C(P＜0.05).Moreover,Group C had significant-ly lower in-hospital mortality and complication rates(P＜0.05).Conclusion The chest pain center"city-wide model"effectively optimizes the STEMI treatment process,significantly shortens in-hospital reperfusion time,improves treatment efficiency,and is associated with reduced mortality and complication rates.It is worthy of broader implementation.
