胸痛中心认证对急性ST段抬高型心肌梗死患者救治效率的影响

目的观察我院胸痛中心认证前后急性ST段抬高型心肌梗死(STEMI)救治关键指标的变化。方法采取回顾性非同期队列研究方式,以我院通过中国胸痛中心联盟正式认证时间为划分时间点,将2017年9月至2018年9月收治的STEMI患者为胸痛中心认证前组(206例),将2018年10月至2019年10月收治的STEMI患者为胸痛中心认证后组(284例)。比较胸痛中心认证前后STEMI患者院前救治、院内救治关键指标的变化以及住院期间死亡率、住院时间和住院费用的差异。结果胸痛中心认证后组心电图(ECG)远程传输比例[122(43.0%)比62(30.1%),P=0.008]和绕行急诊科或CCU比例[117(41.2%)比64(31.1%),P=0.022]与胸痛中心认证前组比较显著增加,首次医疗接触至完成首份ECG(FMC-to-ECG)[3(2,5)min比5(2,7)min,P<0.001]与胸痛中心认证前组比较显著缩短,差异均有统计学意义;两组患者发病至首次医疗接触(S-to-FMC)时间比较,差异无统计学意义(P=0.146)。胸痛中心认证后组ECG至确诊时间[(76.3±57.9)min比(92.0±65.8)min,P=0.040]较胸痛中心认证前组显著下降;胸痛中心认证后组进入医院大门至球囊扩张(D-to-B)时间[76.0(60.0,88.0)min比94.0(78.0,195.0)min,P<0.001]和首次医疗接触至球囊扩张(FMC-to-B)时间[(96.1±67.3)min比(112.4±84.0)min,P=0.022]均较胸痛中心认证前组显著下降,差异均有统计学意义。胸痛中心认证后组D-to-B时间<90 min达标率[201(70.8%)比119(57.8%),P=0.003]和FMC-to-B<120 min达标率[180(63.4%)比101(49.0%),P=0.002]均较胸痛中心认证前组显著增加,差异均有统计学意义。胸痛中心认证后组院内死亡率与胸痛中心认证前组比较,有下降趋势[11(3.9%)比10(4.9%),P=0.654],但差异无统计学意义。胸痛中心认证前后组患者住院时间和住院总费用比较,差异均无统计学意义(均P>0.05)。结论我院胸痛中心认证后较认证前显著缩短了STEMI救治时间,尤其是D-to-B时间,有助于提高胸痛中心STEMI患者的救治效率。

Eff ects of chest pain center certifi cation on the treatment of patients with acute ST-segment elevation myocardial infarction

Objective To compare the changes of treatment indexes of acute ST-segment elevation myocardial infarction after chest pain center certifi cation.Methods Analyze the datas of STEMI in chest pain center,and compare the changes of STEMI pre-hospital treatment,in-hospital treatment index,mortality,length of stay and hospitalization cost before and after chest pain center certifi cation.Results After chest pain center certifi cation,the ECG remote transmission ratio[62(30.1%)vs.122(43.0%),P=0.008]and bypass emergency department or CCU[64(31.1%)vs.117(41.2%),P=0.022]ratio increased significantly.The time of first ECG to diagnosis,D-to-B time and decreased signifi cantly,the pass rate of D-to-B<90 min and FMC-to-B<120 min increased signifi cantly,there was no statistically diff erences in mortality,length of stay,and cost of hospitalization.Conclusions Chest pain center certifi cation can shorten STEMI treatment time and improve STEMI treatment effi ciency.
