急性ST段抬高心肌梗死患者院内死亡发生率的相关因素分析:冠心病介入治疗数据库资料
Analysis of the factor in death rate in hospital of patients with ST-segment elevation myocardial infarction: An analysis of data from Cardiovascular Intervention Procedures Database
【摘要】 目的探讨急性ST段抬高心肌梗死(STEMI)患者发病到血管开通时间与院内死亡发生率的关系。方法分析军队心血管疾病介入诊疗直报系统数据,其中包括冠心病介入治疗资料。研究终点为院内死亡发生率,通过患者年龄及心梗部位进行分层,探讨这两个因素对患者院内死亡发生率的影响。结果全军92家医院行急诊介入治疗的8878例STEMI患者入选本研究。根据从发病到罪犯血管开通的时间将患者分为3组:开通时间≤3h(n=2999)、开通时间3~6h(n=2369)及开通时间>6h(n=3510)。3组患者的院内死亡发生率分别为2.5%、2.9%和3.0%(P=0.405)。其中非前壁心肌梗死且年龄<50岁的患者,若发病3h内接受介入治疗,院内死亡发生率为0.5%;若患者为前壁心肌梗死且年龄>70岁,超过6h才接受介入治疗,则院内死亡发生率可高达7.4%,两者比较差异有统计学意义(P<0.001)。结论 STEMI患者院内死亡发生率与罪犯血管开通时间相关,老年及前壁心梗患者是院内死亡的高危人群。
【Abstract】 Objective To explore the relationship between symptom-onset-to-balloon time and in-hospital mortality in patients with ST elevation myocardial infarction(STEMI). Methods Since October 2010, all cardiovascular intervention procedures in military hospitals were registered online, including coronary interventions. Data in this study were originated from this registry database. Primary endpoint was in-hospital mortality, and it was stratified by age and infarction location to explore the effects of these factors on the mortality rate. Results 8878 STEMI patients from 92 military medical centers were enrolled in this study. These patients were divided into 3 groups by the length of onset-to-vessel opening time: interval ≤3h(n=2999), interval between 3 and 6h(n=2369), and interval >6h(n=3510). The in-hospital mortality rate in those groups was 2.5%, 2.9% and 3.0%, respectively(P=0.405). In interval ≤3h group, mortality rate in young(<50 years) patients with non-anterior MI was 0.5%, while mortality rate in old(>70 years) patients with anterior MI was as high as 7.4%(P<0.001). Conclusions In-hospital mortality rate in STEMI patients is related to onset-to-vessel opening time. Patients with old age or anterior MI are a high-risk cohort.
