摘要 目的 探讨实时三维超声心动图(RT-3DE)评价冠心病室壁运动幅度及舒张功能的临床意义。方法 选取2013年2月~2014年2月就诊的冠心病患者80例作为观察组,按照冠状动脉狭窄程度分为亚组A(50%〈狭窄≤70%)和亚组B(狭窄〉70%)。选取同期健康体检者80例作为对照组。所有纳入对象行RT-3DE检查,计算狭窄动脉对应区域室壁运动的平均位移和平均充盈率,分析两者与动脉狭窄程度的关系。结果 观察组整体室壁平均位移和平均充盈率均明显低于对照组,亚组B各狭窄血管对应节段室壁平均位移和平均充盈率均明显低于亚组A(P〈0.05);经Pearson相关性分析:狭窄血管支配区域室壁平均位移与平均充盈度呈正相关(r=0.673,P〈0.05),两者与血管狭窄程度呈负相关(r=-0.742、-0.728,P〈0.05)。结论 冠心病患者狭窄动脉支配区域室壁的运动幅度和舒张功能均较正常人明显降低,且二者与动脉狭窄的程度呈负相关;RT-3DE为检查心脏功能病变程度提供了一种较为准确且简便、无创的检查手段。
