目的:观察胸痛中心管理模式与急诊绿色通道对急性ST段抬高型心肌梗死(STEMI)患者院前救治率的影响。方法:回顾性选取2017年1月至2019年6月云南省急救中心收治的STEMI患者为研究对象，实施胸痛中心管理模式进行急救的522例为观察组，实施急诊绿色通道进行急救的326例为对照组，比较两组院前、院内急救相关指标、心功能(采用Killip分级法评估)、救治率、住院时间及并发症发生率。结果:观察组出诊反应时间(1.04±0.11)min、首份心电图完成时间(1.56±0.25)min、急救总时间(10.63±2.26)min明显少于对照组[(2.82±0.26)min、(5.99±1.06)min、(18.65±2.98)min]，差异有统计学意义(n P<0.05)；救治后观察组心功能分级明显优于对照组，观察组成功救治率(94.25%)明显高于对照组(42.02%)，住院时间[(6.09±1.02)d]明显短于对照组[(8.92±1.65)d]，并发症总发生率(13.01%)明显低于对照组(32.12%)，差异均有统计学意义(n P<0.05)。n 结论:相较于急诊绿色通道，胸痛中心管理模式不仅可缩短STEMI患者急救相关时间，且可提高患者救治成功率、降低并发症发生率并改善预后，有一定临床推广应用优势。“,”Objective:To observe the effect of chest pain center management model and emergency green channel on pre-hospital rescue rate of patients with acute ST-segment elevation myocardial infarction (STEMI).Methods:Patients with STEMI admitted in Yunnan Provincial Emergency Center between January 2017 and June 2019 were selected as the study subjects. 522 patients with STEMI sent by emergency center were included in the observation group (chest pain center management model of first-aid), while 326 patients with STEMI who came to the hospital by themselves were included in the control group (emergency green channel for first-aid). The pre-hospital and nosocomial first-aid related indexes, cardiac function (assessed by Killip grade), rescue rate, hospital stay and incidence of complications were compared between the two groups.Results:The response time of visit, time of initial electrocardiogram (ECG) completion and total time of first-aid in observation group [(1.04±0.11)min, (1.56±0.25)min, (10.63±2.26)min] were significantly shorter than those in control group [(2.82±0.26)min, (5.99±1.06)min, (18.65±2.98)min, n P<0.05]. The grade of cardiac function in observation group was significantly better than that in control group (n P<0.05). Compared with the control group, the observation group had higher successful rescue rate, shorter hospital stay , lower total incidence of complications [94.25% vs 42.02%, (6.09±1.02)d vs (8.92±1.65)d, 13.01% vs 32.12%,n P<0.05].n Conclusions:Compared with emergency green channel, chest pain center management model can not only shorten first-aid related time of STEMI patients, but also improve their successful rescue rate, reduce incidence of complications and improve prognosis.
