The effect of exercise on left ventricular ejection time in patients with hypertension or angina pectoris.

Using the method and regression equation of Lewis and associates, the present study confirms their findings in normal men up to the age of 65 years. Despite the significantly higher myocardial oxygen consumption, as measured by the double product, the hypertensive patients responded in a similar fashion. The patients with angina pectoris, however, showed a significantly prolonged post-exercise ejection time.
