Echocardiography was conducted on 22 patients with macrofocal myocardial infarction in the first 24 hours of the disease and in the three months following. Zones of asynergy of myocardial contraction were found in all patients. Segmental diminution of myocardial contraction was combined with hyperkinesia of areas of the intact heart muscle. Disturbance in regional myocardial contraction was attended with a decrease in functional capacity of the left ventricle. The left ventricular dysfunction in myocardial infarction is to a greater extent determined by the size and character of the asynergy rather than by the localization of infarction. In the period of recovery normalization of contraction was noted in the hypokinetic zones and to a lesser extent in the zones of akinesia. Zones of paradoxical movements of the wall which had developed in the acute period remained 3 months after the onset of the disease.
对22例大面积心肌梗死患者在发病后的头24小时内及随后的三个月内进行了超声心动图检查。所有患者均发现心肌收缩不同步区域。心肌收缩节段性减弱与完整心肌区域的运动亢进同时存在。局部心肌收缩紊乱伴有左心室功能能力下降。心肌梗死时的左心室功能障碍在很大程度上取决于不同步的大小和特征，而非梗死的部位。在恢复期间，运动减弱区域的收缩恢复正常，运动不能区域的恢复程度较小。急性期出现的室壁矛盾运动区域在发病3个月后依然存在。
