咸宁地区胸痛救治单元建设对急性ST段抬高型心肌梗死患者救治时间及预后的影响OA

Objective To investigate the impact of the establishment of Chest Pain Care Units(CPCUs)in the Xianning region on treatment timelines and clinical outcomes for patients with acute ST-segment elevation myocardial infarction(STEMI)who were transferred and underwent primary percutaneous coronary intervention(PPCI).Methods A retrospective cohort study was conducted by compiling and analyzing data from the Chest Pain Center database at Xianning Central Hospital,covering patients diagnosed with STEMI and treated with PPCI between January 2021 and December 2023.Patients whose initial point of medical contact(first-contact hospital)was a CPCU and who subsequently underwent PPCI were assigned to the CPCU Group(n=280);conversely,patients admitted during the same period whose initial point of medical contact was a non-CPCU facility and who underwent PPCI were assigned to the Non-CPCU Group(n=160).The two groups were compared and analyzed regarding their baseline characteristics,symptom-to-first medical contact time(S2FMC),door-in-door-out time(DIDO),door-to-wire time(D2W),major intraoperative complications,length of hospital stay,hospitalization costs,and the inci-dence of major adverse cardiovascular events(MACE)within 12 months post-discharge.Results In the STEMI patients who received PPCI and were first admitted to the chest pain unit,the results were measured in S2FMC[109.00(60.50,214.00)min vs.136.00(62.75,338.75)min]and DIDO[60.50(45.25,76.75)min vs.82.50(64.00,115.00)min],D2W[49.00(37.25,62.00)min vs.68.00(55.00,83.00)min],hospitalization cost[3.08(2.69,3.54)ten thousand yuan vs.3.21(2.85,3.71)ten thousand yuan]and MACE prescription within 12 months after discharge The facial indexes were all lower than those of the non-chest pain unit group,and the difference was statisti-cally significant(all P＜0.05).Conclusion The construction of chest pain unit can effectively shorten the treatment time,reduce hospitali-zation costs,lower the incidence of cardiovascular adverse events within 12 months post-discharge,and improve the prognosis of patients.
