摘要：

目的探讨老年原发性高血压(EH)患者静息心率(RHR)与靶器官损害的关系。方法入选老年EH患者206例,按RHR水平分为RHR1组<70次/min(56例),RHR2组70次≤RHR<80次/min(84例),RHR3组RHR≥80次(66例)三组。对人选患者做以下检查心电图、超声心动图、颈动脉超声、肌酐清除率以及尿微量白蛋白。结果(1)RHR2组和RHR3组的颈动脉内膜厚度(IMT)、颈动脉内径(CAD)、左心室重量指数(LVMI)以及尿微量白蛋白定量(MAU)均高于RHR1组(P<0.01),而左室射血分数(LVEF)、肌酐清除率小于RHR1组(P<0.01)。(2)RHR与IMT、CAD、LVMI、MAU呈正相关(r分别为0.312、0.289、0.630、0.576,P<0.01),而与LVEF、肌酐清除率呈负相关(r分别为-0.563、-0.510,P<0.01)。(3)非条件Logistic回归分析显示,RHR、收缩压(SBP)、舒张压(DBP)、脉压(PP)对高血压性心脏病、冠心病、心力衰竭、脑血管意外和肾功能损害有不同程度的影响(P<0.05或P<0.01),其中SBP和RHR的作用更大。结论RHR可能是老年EH患者靶器官损害的独立危险因素。
