Echocardiography was conducted in patients who had suffered from myocardial infarction (47 were examined in the subacute period of myocardial infarction and 23 in more remote periods) with signs of mitral insufficiency and 31 patients with no signs of mitral insufficiency (they were examined in the subacute period of myocardial infarction). It was found that after myocardial infarction the contractility of the heart muscle is diminished to a greater extent in patients with signs of mitral insufficiency than in the others. In patients with mitral insufficiency symptoms of circulatory insufficiency were revealed more frequently. The mechanisms of the development of mitral insufficiency in patients with myocardial infarction are discussed.
对患有心肌梗死且有二尖瓣关闭不全体征的患者（47例在心肌梗死亚急性期接受检查，23例在更晚期接受检查）以及31例无二尖瓣关闭不全体征的患者（在心肌梗死亚急性期接受检查）进行了超声心动图检查。结果发现，心肌梗死后，有二尖瓣关闭不全体征的患者心肌收缩力下降的程度比其他患者更大。有二尖瓣关闭不全的患者循环功能不全症状出现得更频繁。文中讨论了心肌梗死患者二尖瓣关闭不全的发生机制。
