摘要： 目的 分析左心室乳头肌水平旋转角度与左室射血分数（LVEF）、左室短轴缩短率（FS）、MAM位移的相关性，探讨其在左室功能评价中的临床价值。 方法 研究对象89例，其中左室收缩功能减退（LVEF <50%）39例，左室收缩正常（LVEF >50%）50例。M型超声心动图测量左室短轴缩短率（FS）、MAM位移；Simpson’s法测量左室射血分数（LVEF）；二维灰阶超声心动图测量左室乳头肌水平旋转角度。 结果 89例研究对象心脏收缩时旋转角度为2.0～13.4度，平均旋转角度（7.73±3.76）度；左室收缩功能减退组较左室收缩正常组LVEF、FS、MAM位移、左室乳头肌水平旋转角度显著减小（P ＜0.001）；左室乳头肌水平旋转角度与LVEF、FS、MAM位移显著正相关（P＜0.001）。 结论 左室乳头肌水平旋转角度可作为评价左室整体收缩功能的一项指标。

Abstract: Objective To analyze the correlation between the torsion angle of left ventricular and LVEF、FS、MAM displacement, and probe the clinical value to evaluate left ventricular function. Methods 89 cases, including 50 patients with LVEF >50% and 39 patients with LVEF<50%, were selected in the study. FS and mitral MAM displacement were measured by M-mode echocardiography, LVEF was measured by Simpson’s, the torsion angle of left ventricular was measured by two-dimensional gray-scale echocardiography. Results All the torsion angles was between 2.0 degree and 13.4 degree, the mean torsion angle was 7.73±3.76 degree. LVEF、FS、MAM displacement and the torsion angle of left ventricular were obviously lower in group with LVEF<50% than that in normal contrast group (P<0.001). The torsion angle of left ventricular was correlated with LVEF、FS 、MAM displacement significantly（P <0.001）. Conclusions The torsion angle of left ventricular can be used to evaluate left ventricular general systolic function．
