摘　　要：目的 探讨原发性高血压患者血压晨峰与血压变异性、心率变异性的相关性。方法 回顾性分析原发性高血压患者123例,行24小时动态血压及动态心电图检查。将其分为晨峰组(MBPS)80例和非晨峰组(NMBPS)43例,对比两组血压变异性及心率变异性等指标,分析血压晨峰与血压变异性及心率变异性的相关性。结果 晨峰组的24小时SSD、dSSD、峰心率显著高于非晨峰组,差异有统计学意义(p<0.05)。MBPS与24hSSD、dSSD、峰心率呈正相关。晨峰组SDNN、SDANN高于非晨峰组,晨峰组r MSSD、PNN50低于非晨峰组。结论 高血压患者晨峰现象与血压变异性、心率变异性有相关性。Objective To study the relation morning blood pressure surge and blood pressure variability and heart rate variability in 123 patients with essential hypertension. Methods One hundred and three patients with hypertension had 24 h ambulatory blood pressure monitoring and 24 h ambulatory dynamic electrocardiogram.According to the results of morning blood pressure surge, 80 patients are selected into the morning blood pressure surge group(MBPS group). Forty-three patients are selected into the morning blood pressure surge normal group(NMBPS group). Blood pressure variability and heart rate variability are compared between the two groups. The correlation between morning blood pressure surge and blood pressure variability and heart rate variability are analyzed. Results Pearson correlation analysis showed that indexes in blood pressure variability as 24 hSSD, dSSD,HR in MBPS are higher than NMBPS have the statistical significance. Indexes in Heart rate variability as SDNN,SDANN, r MSSD, PNN50 in MBPS are higher than NMBPS have the statistical significance. MBPS have positive correlation with 24 hSSD, SSD, and HR. Conclusions Morning blood pressure surge is related with blood pressure variability and heart rate variability.
