摘要 目的观察肺动脉高压(PAH)对右心室收缩功能和收缩同步性的影响。方法选取PAH患者34例,其中轻度PAH者10例(轻度组),中重度者24例(中重度组)。另选择同期相匹配的30例临床及超声心动图检测正常者作为对照组。采用四腔心切面速度成像和应变成像测量室间隔(IVS)、右心室游离壁(RVW)两点及左心室游离壁(LVW)的达峰时间(TTP)并计算相互间的差值。测量右心室收缩末期面积(RVESA)、舒张末期面积(RVEDA)并计算面积变化率(RVFAC),测量等容收缩期加速度(IVA)及三尖瓣环处的收缩期峰值速度(Sm)。结果与对照组比较,组织速度及应变成像测量右心室收缩活动在中重度组明显延迟(P<0.01),而轻度组右心室心肌收缩活动亦出现明显延长(P<0.01),中重度组右心室心肌收缩活动延迟更为明显(P<0.05)。与对照组比较,中重度组RVESA、RVEDA均明显增大(P<0.01),RVFAC、IVA及Sm显著减低(P<0.05)。结论 PAH不仅导致右心室重构改变,降低右心室收缩功能,亦引起了右心室心肌收缩的不同步性,尤其是中重度PAH不同步性更为明显。
