脑卒中发病周期节律研究

Study on Circular Rhythm of Stroke

目的探讨脑卒中发病规律 ,为高危人群防治提供科学依据。方法对住院的 3930例脑卒中病人进行发病时间、卒中类型、发病部位、血压及气温变化的观察 ,每月底及年底进行统计 ,结题前进行总计及分析 ,寻找脑卒中发病的日、年周期规律。结果脑梗死年发病高峰为夏秋季 (5～ 10月 ) ,日发病 2个高峰为～ 8:0 0、～ 16 :0 0 ,且与血压昼夜节律相关。脑出血年发病 3个高峰分别为 1～ 2月、5～ 6月、9～ 10月 ;日发病 3个高峰分别为～ 8:0 0、～16 :0 0、～ 2 0 :0 0 ;蛛网膜下腔出血年发病高峰位于 6、10、11月 ,日发病高峰位于～ 14 :0 0、～ 16 :0 0。结论脑卒中发病有年和时辰周期规律 ,在峰时前实施干预措施可望有效降低脑卒中发病率。

Objective To explore the circular rhythm of stroke. Methods 3 930 patients with stroke were analyzed. The onset time, type, location, blood pressure and the relationship between stroke and weather were observed to study the circular rhythm of stroke. Results Summer and autumn (May to October) were the peak seasons of stroke in a year; 6:00 am to 8:00 am and 14:00 to 16:00 were two peak time in daytime, which were related with the blood pressure rhythm. Three peaks of intracerebral hemorrhage in a year were at January to February, May to June and September to October. The peaks of subarachnoid hemorrhage in a year were at June, October and November. Conclusion Stroke has a circular rhythm in daytime and in a year. Intervention strategy can reduce stroke rate.
