摘要
目的分析急性脑卒中发病的时间。方法统计2675例急性脑卒中患者（脑梗死组1925例,脑出血组750例）的发病时间,从0∶00开始,按每2h为1时段进行分组,对各时段病例数进行分析。结果脑卒中患者发病时间分布与血压24h昼夜节律相似呈双峰曲线,（1）脑梗死组发病时间分布第1峰在6∶00-10∶00,第2峰在18∶00-22∶00,且第1峰值明显高于第2峰值（P〈0.01）;（2）脑出血组发病时段分布与脑梗死组相似,但第2峰值明显高于第1峰值（P〈0.05）。结论脑卒中发病时间与昼夜血压生理节律变化有一定关系,6∶00-10∶00和18∶00-22∶00为高峰时段。
Objective To analysis the time of acute cerebral stroke occurrence. Methods The occurrence time of 2675 patients with cerebral infarction （ 1925 cases, CI group） and intraeerebral hemorrhage （ 750 cases, ICH group） were statisticed by 1 time unit per 2 h from 0： 00. Results There was a time-curve with double peaks of stroke occurrence,like as circadian rhythms of blood pressure in 24 h. （1） In CI group, the first peak was 6：00 - 10： 00, the second peak was 18：00 -22： 00. The value of the first peak was higher than that of the second （P 〈 0. 01 ）. （2） The time-curve of ICH group was similar to CI group,but the value of second peak was higher than that of the first （ P 〈 0：05 ）. Conclusions There is correlation between the occurrence time of stroke and circadian rhythms of blood pressure. The peak times of stroke occurrence are 6：00 - 10：00 and 18：00 -22： 00.
