摘要
目的探讨老年高血压患者家庭自测血压变异性（BPV）与心率变异性的相关性。方法2011年10月～2013年4月，对172例老年高血压患者进行7d家庭自测血压以及24h动态一心电图监测。根据家庭自测BPV三分位分为低变异性组56例、中变异性纽62例和高变异性组54例。结果与低变异性组比较，中变异性组和高变异性组24h连续正常R—R间期的标准差（SDNN）、连续正常R—R间期均值的标准差（SDANN）、相邻正常RR间期的差值均方根（rMSSD）及低频明显降低（P〈0．05）；与中变异性组比较，高变异性组sDNN、SDANN、rMSSD及低频明显降低（P〈0．05）。多元线性逐步回归分析显示，家庭收缩压变异性与SDNN、SDANN、rMSSD和低频呈负相关（P〈0．05），与极低频呈正相关（P〈0．05）；家庭舒张变异性与吸烟呈正相关（P〈0．05），与SDNN呈负相关（P〈0．05）。结论老年高血压患者BPV与24h心率变异性密切相关。
Objective To study the relation between blood pressure variability （BPV） and heart rate variability （HRV） measured by elderly hypertensive patients themselves at home. Methods One hundred and seventy two elderly hypertensive patients,who measured their blood pressure themselves for 7 consecutive days at home and underwent 24 h ECG monitoring from October 2011 to April 2013 ,were divided into low BPV group （n=56）,moderate BPV group （n=62）,and high BPV group （n=54）. Results The SDNN,SDANN,rMSSD and low frequency were signifi- cantly lower in moderate and high BPV groups than in low BPV group （P〈0.05） and in high BPV group than in moderate BPV group （P〈0.05）. Correlation and regression analysis showed that the systolic BPV at home was negatively related with the SDNN, SDANN, rMSSD and low frequency while the diastolic BPV at home was positively related with smoking and negatively related with SDNN （P〈0.05）. Conclusion The BPV is closely related with the 24 h HRV in eld- erly hypertensive patients at home.
