摘要 目的:分析超声心动图评价肺动脉高压患者左心功能的价值。方法:收集2012年2月至2014年8月诊断为肺动脉高压的患者120例作为为观察组;对照组为同期心功能正常的健康者120例。测定并比较两组舒张早期最大流速/舒张晚期最大流速比值、E峰下降时间、左心室等容舒张时间及左心室舒张末期容积、左心室收缩末期容积、左室射血分数。结果:(1)观察组舒张早期最大流速/舒张晚期最大流速比值低于对照组,E峰下降时间、左心室等容舒张时间长于对照组(P<0.05);(2)观察组左心室舒张末期容积、左心室收缩末期容积值低于对照组(P<0.05),观察组和对照组左室射血分数值差异无统计学意义(P>0.05)。结论:本次研究认为肺动脉高压患者左心收缩及舒张功能存在不同程度减弱。
