The right ventricular ejection fraction was determined in 58 patients with simultaneous right and left ventricular myocardial infarction and in 77 patients with only left ventricular myocardial infarction. The results were analysed in four groups of patients (patients with anterior, anterior and right ventricular, posterior, posterior and right ventricular myocardial infarction). Furthermore, the relation between left and right ventricular ejection fraction, stress capacity and heart volume was investigated. There was no influence of the age and gender of patients on the observed values of right and left ventricular ejection fraction. In younger patients, after myocardial infarction, the heart volume was found to be less and the stress capacity to be higher then in elderly patients. The right ventricular ejection fraction was normal in patients with "poor" left ventricular infarction, and it was decreased in patients with right ventricular myocardial infarction. The right ventricular ejection fraction did not influence the stress capacity and the heart volume of the patients. The left ventricular ejection fraction found to be less in anterior, compared to posterior myocardial infarction. This difference was independent on the presence of right ventricular infarction. The authors consider the decreased right ventricular ejection fraction as a valuable indicator of the abnormal contractility of the right ventricle even at the time of the rehabilitation after myocardial infarction.
对58例同时发生右心室和左心室心肌梗死的患者以及77例仅发生左心室心肌梗死的患者测定了右心室射血分数。结果在四组患者（前壁、前壁合并右心室、后壁、后壁合并右心室心肌梗死患者）中进行了分析。此外，还研究了左、右心室射血分数、应激能力和心脏容积之间的关系。患者的年龄和性别对右心室和左心室射血分数的观测值没有影响。在年轻患者中，心肌梗死后心脏容积比老年患者小，应激能力比老年患者高。“严重”左心室梗死患者的右心室射血分数正常，而右心室心肌梗死患者的右心室射血分数降低。右心室射血分数不影响患者的应激能力和心脏容积。与后壁心肌梗死相比，前壁心肌梗死患者的左心室射血分数较低。这种差异与右心室梗死的存在无关。作者认为，即使在心肌梗死后康复期，右心室射血分数降低也是右心室收缩功能异常的一个有价值指标。
