The influence of coronary and myocardial lesions, defining the severity of the coronary artery disease on effort tolerance was studied in 51 patients. The appearances of the coronary arteriography and ventriculography were compared with the parameters of exercise tolerance: electrocardiographic changes, maximal charge (Cw), total work (TW), maximal systolic arterial pressure (SAP), maximal heart rate, percentage of the theoretical maximal heart rate, double product, exercise capacity index (CEI). The results showed that exercise tolerance (Cw, TW, ECI) and the exercise SAP are mainly affected by the myocardial lesions: patients with very reduced left ventricular ejection fractions and double or triple artery disease have very low indices: average Cw of 60 watts, TW less than 20,000 joules, ECI approximately 50. The SAP only rises slightly. On the other hand, patients with normal or subnormal ejection fractions have much higher indices whatever the state of their coronary arteries; Cw over 80 watts, TW over 30,000 joules, ECI over 80. In addition, major left ventricular dysfunction is associated with ST segment elevation during exercise.
