title: [Left ventricular function with effort in the coronary patient. Study of the correlations with the data on echocardiography, effort ECG, and the teleheart. 2].
abstract: Correlations were established, for 30 coronary patients, between the haemodynamic findings and those adduced from non-invasive techniques - electrocardiography, both at rest and on exercise, telethorax, and echocardiography. Left ventricular function in the coronary patient can be assessed, even before catheterisation, by means of: 1. The clinical findings: angina of effort, an uncomplicated infarct, and an infarct with sequelae each has its own peculiar haemodynamic pattern at rest and on exercise; 2. The ECG finding of an extensive anterior infarct implies a haemodynamic picture vastly different from that with a limited posterior infarction; 3. The appearance of an ischaemic shift in the ST segment on exercise implies an acute malfunctioning of the left ventricle; 4. On the echocardiogram, an end-diastolic volume greater than 150 ml/m2, an ejection fraction less than 0.50 and VCF greater than 0.8 c/s are always accompanied by disturbances in the haemodynamics. By contrast, the cardio-thoracic ratio, except in post-infarct cases complicated by left ventricular failure, gives no predictive indication of cardiac function. These various examinations should therefore be applied to the coronary patient as an index of cardiac function.
