The relationship was examined between the severity of heart failure, the degree of asynergy and exercise tolerance in 40 males under 60 years with postinfarction cardiosclerosis. Fifteen healthy males were matched for as a control. Echocardiography was performed before and after bicycle ergometer exercise test, allowing the patients to be divided into 4 groups: Groups 1 and 2 without an ischemic response in the absence or presence of akinesia or dyskinesia, respectively; Groups 3 and 4 with an ischemic response in the absence or presence of akinesia or dyskinesia, respectively. The lowest exercise tolerance was observed in Group 4. Echographic findings showed that the overall left ventricular contractility was diminished in all the patients; there was no noticeable quantitative difference in the values between the groups. No differences were found in segmental ejection fractions. The combination of ischemic response to exercise tolerance and akinesia-dyskinesia asynergy indicates a more severe disease of the coronary bed and myocardium.
对40名60岁以下患有心肌梗死后心硬化的男性患者，研究了心力衰竭严重程度、运动不协调程度与运动耐力之间的关系。选取15名健康男性作为对照进行匹配。在自行车测力计运动试验前后进行超声心动图检查，将患者分为4组：第1组和第2组分别在无运动不能或运动障碍时无缺血反应；第3组和第4组分别在无运动不能或运动障碍时有缺血反应。第4组的运动耐力最低。超声心动图结果显示，所有患者的左心室整体收缩力均降低；各组之间的值无明显定量差异。节段射血分数无差异。运动耐力的缺血反应与运动不能 - 运动障碍性运动不协调相结合，表明冠状动脉床和心肌疾病更严重。
