摘　　要：目的:探讨急性中风病例死亡时间的昼夜节律变化特点和规律。方法:回顾性分析180例急性中风死亡患者死亡时间,利用圆形分布的统计方法计算出死亡高峰时刻和24 h内95%的死亡时间集中时间段。结果:急性中风患者严格统计学意义上的死亡高峰时间是不存在的(P>0.10),相对的死亡高峰时刻为清晨07:24;出血性脑血管病患者死亡高峰时刻为清晨07:48;缺血性脑血管病患者的死亡高峰时刻为清晨05:43。结论:脑血管病患者死亡时间有一定的昼夜节律分布特点,清晨通常为死亡的高峰时段,工作中应加强夜间和凌晨患者的管理和监测,对减少病死率有积极意义。Objective：To investigate the circadian variation rhythm of time of death in patients with acute stroke. Methods： The time of death of 180 eases with acute stroke was analyzed by circular statistical analysis. The peak time of death and the period of 95% deaths in 24 hours daily were calculated. Results.. There was no significant difference on the peak time of death （P〉0.10）, the relative peak time of death was at 07：24; the peak time of hemorrhagic stroke death was at 07：48; and the peak time of ischemic stroke death was at 05 ： 43. Conclusion ： There is a certain circadian variation rhythm of time of acute stroke death, and the peak time is always in the early morning, indicating that it is important to manage and monitor acute stroke patients at midnight and early morning, which may result in the decrease of mortality of acute stroke.
