| 摘 要： | 目的:探讨组织运动二尖瓣环位移自动追踪技术(TMAD)在评价急性心肌梗死(AMI)患者左心室整体收缩功能中的临床应用价值。方法:选取AMI患者29例为AMI组,年龄匹配的健康志愿者31例为对照组,采用Philips IE33彩色超声诊断仪,行常规超声心动图检查,应用双平面Simpson法测量左心室舒张末容积、左心室收缩末容积和左心室射血分数(LVEF)。存储心尖四腔、三腔和两腔连续3～5个心动周期二维动态图像,用Qlab 7.0软件进行脱机分析,测量二尖瓣环6个位点收缩期最大位移(Ds)、瓣环连线中点最大位移(D-mid)和左心室长轴缩短率(FSL),分别计算其均值,并与简化双平面Simpson测量的LVEF做相关分析。结果:①与对照组相比,AMI组二尖瓣环6个位点Ds、D-mid、FSL及其均值显著降低,均差异有统计学意义(均P<0.001);②2组Ds均值、D-mid均值及FSL均值与LVEF均具有相关性(AMI组r分别为0.787、0.776和0.779,P<0.001;对照组r分别为0.662、0.706和0.759,P<0.001);③重复性检验:AMI组Ds均值、D-mid均值及FSL均值观察者内...
