摘要: 目的探讨慢性肾脏病伴高血压患者(HCKD)动态血压及心率变异性(HRV)的变化特点.方法随机选择56例HCKD患者,44例原发性高血压(EH)患者和43例正常对照组,同步监测动态血压和动态心电图,并对比分析其动态血压参数及HRV变化的特点.结果与EH组比较,HCKD组的动态血压参数平均24 hS-BP、平均24 hDBP、平均NSBP、平均NDBP高于EH组(P<0.05),HCKD组发生非杓型血压比例(89.28%)高于EH组(70.46%)(P<0.05),而HRV时域法指标:SDNN、SDANN、rMSSD、PNN50均低于EH组,差异有统计学意义(P<0.05).结论HCKD患者平均24 h及夜间血压增高、血压昼夜节律异常、HRV明显降低.Abstract: Objective To investigate the characteristics of changes of ambulatory blood pressure and heart rate variability(HRV)in patients with chronic kidney disease with hypertension(HCKD).Methods 56 patients with HCKD,44 patients with essential hypertension(EH)and 43 normal subjects were selected randomly,and their ambulatory blood pressure and dynamic electrocardiogram were simultaneously monitored to compare and analyze their ambulatory blood pressure parameter and the varied characteristics of HRV.Results Compar...
