摘要：

目的 :利用左室质量比值 (%PLM )将左室重构分为左室质量适宜 (aLVM )、左室质量过高 (iLVM )和左室质量不足 ,观察并比较aLVM和iLVM的心脏结构和功能特点。方法 :对 187例原发性高血压 (EH)患者进行超声心动图检查 ,测量其心脏结构和功能。结果 :aLVM、iLVM和左室质量不足的分布分别占 4 8.1%、4 8.7%和 3.2 %。与aLVM相比 ,iLVM的主动脉根部内径、左房内径、左室质量和相对室壁厚度更高 (P <0 .0 5 ) ;心排血量、心搏量、左室射血分数、左室短轴缩短率和舒张早期充盈峰速度E峰 /舒张晚期充盈峰速度A峰比值更低 (P <0 .0 5 ) ;总外周血管阻力更高 (P <0 .0 5 )。结论 :与aLVM相比 ,iLVM的心脏结构和功能特点提示它是左室重构发展的进一步阶段。
