     [摘要] 目的应用组织多普勒成像(TDI)技术测定冠心病病人左心室长轴功能，并探讨其临床应用价值。方法选择在我院接受治疗的冠心病病人48例，应用TDI技术获得二尖瓣环沿左心室长轴的运动频谱，测量收缩期心肌峰值运动速度(SM)、收缩期位移(DS)及收缩前期时间(PCTM)，舒张早期心肌峰值运动速度(EM)，心房收缩期心肌峰值运动速度(AM)，计算EM/AM比值及左心室射血分数(EF)。结果冠心病组与正常对照组比较，SM和DS显著减小(t=2.78、9.61，P<0.01)；PCTM显著增加(t=2.49，P<0.05)；EM显著减小(t=5.45，P<0.01)；EM/AM比值显著减小(t=4.94，P<0.01)；冠心病病人SM和DS与EF、EM呈明显正相关(r=0.58~0.72，P<0.01)。结论冠心病病人存在左心室长轴功能受损，TDI技术为准确评价左心室长轴功能提供了一条新途径。

    [ABSTRACT]ObjectiveTo measure the left ventricular longaxis function in patients with coronary artery disease and to investigate its clinical significance. MethodsThe longaxis function parameters were measured with tissue Doppler imaging (TDI) in 48 patients with coronary artery disease in mitral annulus level, including peak systolic velocity (SM) and excursion (DS), the time interval from ECG Q wave to SM (PCTM), early diastolic peak velocity (EM), late diastolic peak velocity (AM) and EM/ AM. ResultsCompared with the control group, SM and DS decreased (t=2.78 ......
