This work is based on the results of a systematic scheme of investigation consisting of an exercise test on the bicycle ergometer with analysis of the ECG and of the pulmonary arterial pressure measured by cardiac micro-catheterisation, and of ventricular and coronary arteriography; 60 patients were investigated in this way after the third month following a myocardial infarction. After an anterior infarction, there is no significant correlation between the ECG changes and the coronary arteriogram. An elevation of the tracing is often (but not always) indicative of akinesia or dykinesia of the ventricle. After a posterior infarction, depression of the trace in leads which were initially normal indicates extension of the coronary lesions in 9 cases out of 10. It, is, however, possible for a tight stenosis on the anterior descending artery to exist with no changes on the ECG. A highly significant (p less than 0.001) and strong (r=0.83) correlation between an index of haemodynamic severity as defined by variations in the pulmonary arterial pressure on exercise and by the score on coronary arteriography, allows us to define certain indications for coronary arteriography and ventriculography after infarction.
这项工作基于一个系统的调查方案的结果，该方案包括在自行车测力计上进行运动测试，并分析心电图、通过心脏微导管测量的肺动脉压以及心室和冠状动脉造影；在心肌梗死后第三个月，对60例患者进行了这样的调查。在前壁心肌梗死后，心电图变化与冠状动脉造影之间无显著相关性。描记图升高通常（但不总是）提示心室运动减弱或运动障碍。后壁心肌梗死后，最初正常导联的描记图压低在10例中有9例提示冠状动脉病变扩展。然而，前降支动脉严重狭窄时心电图可能无变化。运动时肺动脉压变化所定义的血流动力学严重程度指数与冠状动脉造影评分之间存在高度显著（p<0.001）且很强的相关性（r=0.83），这使我们能够确定心肌梗死后冠状动脉造影和心室造影的某些指征。
