目的:探讨脑梗死发病的时间分布节律性。方法:选取2012年-2013年黑龙江省康复医院收治的40例脑梗塞患者为研究对象,根据患者发病的时间按小时、日和月份进行回顾性分析。结果:脑梗死发病具有日、周、年节律性规律。结论:应该高度重视脑梗塞发病时间分布的节律性,对其发病高峰段提前进行干预性治疗,从而有效降低发病率并减小梗死面积及降低病残率。 Objective: To investigate the rhythm of time distribution of cerebral infarction. Methods: Forty cerebral infarction patients who were treated in Heilongjiang Rehabilitation Hospital from 2012 to 2013 were selected as the research objects. The incidence of the disease was analyzed retrospectively by hour, day and month. Results: The incidence of cerebral infarction with day, week, year rhythms. Conclusion: It is necessary to attach great importance to the rhythm of the distribution of the time of onset of cerebral infarction and preliminarily carry out interventional treatment on the peak of its onset, thereby effectively reducing the incidence and reducing the infarct size and reducing the morbidity.
