abstract

  • 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 decreased significantly in uncontrolled hypertensives (p less than 0.001). Control of hypertension resulted in significant improvement of exercise performance in both the groups. Atenolol, when compared to captopril, resulted in better exercise conditioning with considerable lowering of resting and peak RPP and MVO2 (p less than 0.001), though the difference in exercise duration, maximum work load and recovery time were not significant (p greater than 0.05). Thus, where myocardial oxygen consumption is an important consideration while treating hypertension, atenolol offers a better choice.
