目的:评价早期TIMI评分对急诊室ST段抬高型心肌梗死(STEMI)患者30 d预后的预测价值。方法:使用前瞻性观察研究的方法,收集2012年3月17日至2013年8月14日在我院急诊室首诊的年龄≥18岁确诊的STEMI患者。记录患者临床资料,完成TIMI评分的计算,并对纳入的病例进行30天的随访。随访的内容为30天心血管不良事件。结果:本研究共收集了119例STEMI患者,平均年龄为65.8±13.3岁,男性患者占82.4%。患者30天的心血管不良事件的发生率为14.3%。TIMI评分对30天全因死亡有良好的预测价值,AUC分别是0.785,统计学Cutoff为>5时的敏感性为82.3%,特异性为59.8%,TIMI评分≤2分者的患者30天内没有发生死亡,其敏感性达到100%,特异性为21.57%。结论:TIMI评分能有效地预测急诊室STEMI患者30天的预后,Cutoff值可根据受试人群的情况进行调整。
PURPOSE: To evaluate the predictive value of early TIMI score on the 30-day prognosis of patients with ST-segment elevation myocardial infarction (STEMI) in emergency department. METHODS: A prospective observational study was performed to collect STEMI patients ≥18 years of age who were first diagnosed in our emergency department from March 17, 2012 to August 14, 2013. The clinical data were recorded and the TIMI score was calculated. The included cases were followed up for 30 days. Follow-up of 30 days of cardiovascular adverse events. Results: A total of 119 STEMI patients were collected in this study, with an average age of 65.8 ± 13.3 years and 82.4% of male patients. The 30-day incidence of cardiovascular adverse events in patients was 14.3%. The TIMI score had good predictive value for 30-day all-cause mortality with a AUC of 0.785, a statistically significant cutoff of> 5 at 82.3%, a specificity of 59.8%, and a TIMI score of ≤2 within 30 days In the event of death, the sensitivity is 100% and the specificity is 21.57%. Conclusion: The TIMI score can effectively predict the 30-day prognosis of STEMI patients in emergency room. The Cutoff value can be adjusted according to the test population.
