A total of 54 myocardial infarction survivors and 20 normal subjects were examined echo- and polycardiographically. The movement of left ventricular wall was studied within and outside the affected area. A hypokinetic zone was identified in all the patients after the posterior myocardial infarction. The measurement of posterior wall movement amplitude before expulsion is over improves the chances of echocardiographic identification of the hypokinetic zone in patients with lower localization of myocardial infarction. Apart from reduced amplitude and rate of contraction, and myocardial thinning, the hypokinetic zone reveals paradoxical myocardial thickening during the early diastole, and shorter duration of affected area relaxation, while intact myocardium relaxes early. It is suggested that disorders relaxation in myocardial infarction survivors precedes contraction disorders, with hypokinetic myocardium relaxing mostly passively, and intact myocardium relaxation being of a more active nature and independent of the filling phase.
对54名心肌梗死幸存者和20名正常受试者进行了超声心动图和多心电图检查。研究了梗死区域内外左心室壁的运动情况。所有下壁心肌梗死后的患者均发现有运动减弱区。在射血结束前测量后壁运动幅度，可提高超声心动图识别心肌梗死较低部位患者运动减弱区的几率。除了收缩幅度和速率降低以及心肌变薄外，运动减弱区在舒张早期显示出矛盾性心肌增厚，且梗死区域舒张持续时间较短，而正常心肌舒张较早。提示心肌梗死幸存者舒张功能障碍先于收缩功能障碍，运动减弱的心肌大多被动舒张，而正常心肌舒张更具主动性且与充盈期无关。
