摘要(Abstract)：
目的:观察阻塞性睡眠呼吸暂停低通气综合征(OSAHS)对脑梗死后遗症患者心率变异及血压昼夜节律的影响。方法:脑梗死后遗症患者128例,根据是否伴有OSAHS分为:单纯脑梗组66例,合并OSAHS组62例,另选择同期健康体检者60例作为正常对照组。监测并比较3组昼夜血压值和"非杓形"血压患者的比例,心率变异的时域指标及频域指标,血氧饱和度及睡眠呼吸紊乱指数(AHI)。结果:合并OSAHS组患者的昼夜血压值、"非杓形"血压患者的比例、心率变异的时域指标及频域指标及AHI均高于其他2组(P<0.05),夜间最低血氧饱和度和夜间平均血氧饱和度均低于其他2组(P<0.05);单纯脑梗组的昼夜血压值、"非杓形"血压患者的比例及AHI高于正常对照组(P<0.05),夜间最低血氧饱和度和夜间平均血氧饱和度均低于正常对照组(P<0.05)。结论:脑梗死后遗症合并OSAHS患者的血压昼夜节律呈非杓型,心率变异增强,夜间血氧水平下降,AHI明显增加。
