摘要 目的探讨应用二维超声斑点追踪成像评价左室旋转的临床意义。方法对27例肥厚型心肌病患者(HCMD组)、20例冠心病患者(CAD组)和43例对照者(对照组),采用GEVivid7Dimension超声心动图仪和GEEchoPac PC6.1.0数据分析系统,测量收缩末期左室基底部、中间部及心尖部的旋转角度(ROT)及旋转率(ROTR)。结果对照组的左室基底部与中间部的ROT为负值,心尖部的ROT为正值。HCMD组和CAD组的左室基底部ROT变化与对照组比较差异无统计学意义(P〉0.05),CAD组心尖部与中间部的ROT及ROTR变化与对照组比较差异均有统计学意义(P〈0.05或〈0.01)。结论二维超声斑点追踪成像是目前测量心脏旋转的最佳手段,ROT及ROTR的变化反映了心室运动的扭转,对评估心肌收缩功能具有重要的临床意义。
