摘要
目的 探讨老年高血压病患者静息心率 (restingheartrate ,RHR)与靶器官损害的关系。方法 入选老年高血压病患者 2 0 6例 ,按收缩压 (SBP)水平分为三组 :SBP <16 0mmHg(1mmHg =0 133kPa) ,16 0mmHg≤SBP <180mmHg ,SBP≥ 180mmHg。在以上每一组中 ,又按RHR水平分为 :RHR1组 ,<6 5次 /min ;RHR2组 ,6 5次 /min≤RHR <6 9次 /min ;RHR3组 ,70次 /min≤RHR <74次 /min ;RHR4组 :75次 /min≤RHR <79次 /min ;RHR5组 ,RHR≥ 80次 /min。对入选患者做以下检查 :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)RHR5组的尿微量白蛋白定量和左心室质量指数均高于RHR1~RHR4各组 (P <0 0 5或P <0 0 1)。RHR5组或RHR4组的颈动脉内膜厚度和颈动脉内径大于RHR1和RHR2组 ;而左室射血分数和肌酐清除率小于RHR1和RHR2组 (P <0 0 5或P <0 0 1)。(2 )RHR与颈动脉内膜厚度、颈动脉内径、左心室质量指数、尿微量白蛋白定量呈正相关 (r分别为 0 312、0 2 89、0 6 30、0 5 76 P <0 .0 1) ,而与左室射血分数、肌酐清除率呈负相关 (r分别为 - 0 5 6 3、- 0 5 10 ,P <0 .0 1)。结论 RHR的增加是老年高血压病患者靶器官损害的重要危险因素。
