摘要 目的探讨血压变异性(BPV)与左室肥厚(LVH)的相关性。方法对112例原发性高血压患者进行24 h动态血压监测和超声心动图检查,比较伴LVH和不伴LVH组患者24 h,日间,夜间的收缩压(SBP)和舒张压(DBP)标准差(SD)差异,采用Pearson相关系数和多因素回归系数评价左室重量指数(LVMI)与SD的相关性。结果伴LVH患者的24 h SBPSD、日间SBP-SD和夜间SBP-SD均高于不伴LVH患者(P<0.05),24 h DBP-SD、日间DBP-SD和夜间DBP-SD间均未发现有统计学差异(P>0.05);患者左室重量指数(LVMI)与24 h SBP-SD呈正相关(r=0.501,P<0.05),与24 DBP-SD无相关性(r=0.141,P>0.05);24 h SBP-SD、日间SBP-SD、夜间SBP-SD值与LVMI独立相关,回归系数分别为0.167,0.093,0.196。结论 LVH形成过程中,SBP变异性增加比DBP变异性更为重要,且以夜间BPV影响最大。
