Cardiovascular response to dynamic treadmill exercise in patients with essential hypertension before and after therapy with atenolol or captopril.

Thirty eight patients with essential hypertension and 20 healthy volunteers were subjected to treadmill exercise test. The hypertensives were then controlled with atenolol or captopril by randomly forming two groups of 19 patients each, and treadmill evaluation was repeated. The resting rate-pressure product (RPP) and myocardial oxygen consumption (MVO2), as well as peak RPP and MVO2 and recovery time, were increased and exercise duration …
