摘要 目的探讨急性心肌梗死(AMI)院前延迟(PHD)的影响因素及其对预后的影响。方法采用问卷调查、出院随访、查阅病历收集资料等方法,对332例AMI患者PHD影响因素及对预后的影响进行分析。结果患者延迟(PD)中位数时间为90min;PHD中位数时间为170min;PD占PHD的46.6%~64.5%;PHD越长,PD在PHD中所致的比例越大。多因素Logistic回归分析显示,梗死前心绞痛、服止痛药、不愿打扰别人、等症状消失、逐渐发病、年龄≥65岁、无医疗保险是PD的独立危险因素。以PD60min为界点,与晚决定组相比,早决定组患者发病至再灌注治疗延迟明显缩短;AMI患者PHD≤2h组,1年内无心血管事件发生;>2h组心血管事件发生率为27.03%,与前者比较有显著差异(P<0.05)。结论AMI患者延迟就医受多种因素影响,PD是影响PHD的主要因素,PD使AMI患者1年心血管事件发生率增高。缩短PHD,并及早实施再灌注治疗,对降低AMI患者病死率并改善远期预后至关重要。
