非正常工作时间急诊经皮冠状动脉介入术对急性心肌梗死预后的影响

目的探讨行急诊经皮冠状动脉介入术（PCI）的时间与急性心肌梗死（STEMI）患者预后的关系。方法将585例STEMI患者根据急诊PCI时间分组，回顾性对比分析其临床特征及短期预后情况。结果与正常工作时间组比较，非正常工作时间组患者高血压病史者、吸烟者比例以及年龄、白细胞计数（WBC）、超敏C-反应蛋白（hs—CRP）、B型脑钠肽前体（NI-pro-BNP）较正常工作时间组更低，住院期间心脏合并事件发生率更低（P均〈0．05）。结论非正常工作时间内接受急诊PCI治疗STEMI者病情相对较轻，住院期间合并心血管事件发生率更低。

Objective We investigated to evaluate the relationship between emergency percutaneous coronary intervention （ PCI ） timing （ off-hour versus regular-hour ） and in-hospital outcome in patients with ST-segment elevation myocardial infarction （ STEMI ） in area of Suzhou. Methods 585 patients with STEMI treated by emergency PCI were divided into ＂off-hour group＂ and ＂regular-hour group＂ according to time of interventions. We retrospectively analyzed the differences between the two groups by baseline characteristics, angiography characteristics, treatments and in-hospital combined cardiac events. Results Less patients of off-hour group had hypertension and smoking history, and with lower levels of age, white blood cell （ WBC ） count, high-sensitivity C-reactive protein （ hsCRP ） and N-terminal-proB-type natriuretic peptide （ NT-pro-BNP ） than those of regular-hour group （ 〈0.05 ） . Off-hour group had less in-hospital combined cardiac events than regular-hour group （ P〈0.05 ） .Conclusion Patients with STEMI receiving emergency PCI during off-hour are with better condition and had less in-hospital combined cardiac events.
