摘要(Abstract):
目的探讨75岁以上老年ST段抬高型心肌梗死(STEMI)患者接受直接经皮冠状动脉介入治疗(PCI)后长期随访中发生死亡事件的危险因素。方法 2011年9月至2014年1月阜外医院共完成PCI 27 397例,完成急诊PCI 1644例,本研究采用回顾性研究方法,连续收集其中老年(年龄≥75岁)STEMI并行直接PCI的患者108例,并持续进行随访,分析患者资料,通过Cox比例风险模型分析死亡事件的独立危险因素。结果所有患者均行直接PCI,平均随访(51.17±17.75)个月。院内死亡5例(4.6%),术后30 d死亡7例(6.5%),随访期间死亡17例(15.7%)。1年死亡的独立危险因素包括女性(HR 5.482,95%CI 1.099~27.333,P=0.038)、心源性休克(HR 11.283,95%CI 2.841~44.805,P=0.001),而支架置入术(HR 0.173,95%CI 0.032~0.943,P=0.043)是死亡事件的保护性因素。长期随访显示,死亡的独立危险因素包括年龄(HR 1.146,95%CI 1.010~1.300,P=0.034)、心源性休克(HR 4.928,95%CI 1.718~14.130,P=0.003)。结论高龄、女性、心源性休克、未行支架置入术是75岁以上老年STEMI患者直接PCI术后发生死亡的危险因素。
