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.
