前后循环脑梗死患者动态血压特点分析

目的:通过24h动态血压监测研究前后循环梗死患者的血压特点。方法:将150例合并高血压病的急性脑梗死患者分为前循环梗死组(69例)和后循环梗死组(81例),对其进行24h持续血压监测,对比两组患者血压水平和血压变异性的特点。结果:对两组患者血压基础水平的比较发现前循环梗死组血压高于后循环梗死组血压,但除平均收缩压(SBP)、夜间收缩压(nSBP)外其他指标无统计学差异(P>0.05);对血压变异性指标的对比发现后循环梗死组的血压变异性高于前循环梗死组,收缩压变异(SSD)、白昼收缩压变异(dSSD)、白昼舒张压变异(dDSD)、夜间收缩压变异(nSSD)差异有统计学意义(P<0.05)。结论:血压变异性增高可能是后循环脑梗死的重要因素之一。

Character of dynamic blood pressure of patients with cerebral infarction in anterior circulation and posterior circulation

Objective: To explore the character of dynamic blood pressure of patients with cerebral infarction in anterior circulation and posterior circulation.Methods:A total of 150 patients with acute cerebral infarction and high blood pressure were randomly divided into anterior circulation group(69 cases) and posterior circulation group(81 cases).The blood pressure was monitored continuous for 24 h,and compared between two groups.Results:The blood pressure was higher in anterior circulation group.There were significant differences only in SBP and nSBP.Patients in posterior circulation group had higher blood pressure variability,and there were significant differences in SSD,dSSD,dDSD and nSSD.Conclusions:Increased blood pressure variability maybe important factor of cerebral infarction in posterior circulation.
