慢性顽固性失眠合并高血压的血压特点分析

Characteristic of the blood pressure circadian rhythms on the patients suffered chronic insomnia and hypertension

目的探讨慢性失眠合并高血压患者血压变化特点。方法选择慢性失眠合并高血压患者60例,根据使用降压药数量分为3组,无失眠及高血压正常人20例为对照组进行多导睡眠监测、24h动态血压监测,观察各组睡眠及血压变化情况。结果与对照组相比,慢性失眠合并高血压组患者总睡眠时间缩短(P<0.01),睡眠效率下降(P<0.01),睡眠潜伏期延长(P<0.01),觉醒时间增加(P<0.01),3组患者白昼血压与夜间血压差值变小,血压失去昼夜节律,大部分呈非杓形。结论慢性失眠合并高血压患者血压控制差,血压丧失昼夜节律,大部分呈非杓形。

Objective To analyze the blood pressure circadian rhythms of the patients suffered insomnia and hypertension. Methods 60 patients were divided into three groups according medicine,and 20 normals as control group. All participants were underwent polysomnography recording and ambulatory blood pressure monitoring to evaluate the changes of sleep and blood pressure. Results Patient＇s total sleep time decrease （P〈0.01） ,sleep efficiency descended （P〈0.01） ,sleep latency increased （P〈0.01）, wake after sleep onset enhanced （P〈0. 01）, patient＇s blood pressure disappeared day-night circadian rhythms. Conclusion The blood pressure on the patients suffered chronic insomnia and hypertension don＇t be control well. Their blood pressure circadian rhythms appear non-dipper blood pressure.
