Abstract

The effects of mental, static and dynamic stresses on physiologic parameters before and after β-blocker (n = 24) and angiotensin-converting enzyme inhibitor (n = 29) treatment were examined. Mental stress induced similar elevation in systolic and diastolic blood pressures (BPs) with and without β-blocker treatment. During angiotensin-converting enzyme inhibitor treatment, the change in systolic BP was significantly greater (p < 0.05). Heart rate response was attenuated by β blockers and unchanged by the angiotensin-converting enzyme inhibitor. Skin temperature and galvanic skin resistance significantly decreased (p < 0.05) with mental stress. Beta blockers did not change the response pattern, whereas the angiotensin-converting enzyme inhibitor attenuated the stress-induced reduction of both skin temperature and galvanic skin response. After handgrip exercise, increases in systolic and diastolic BPs and heart rate were similar before and after β-blocker treatment, whereas the angiotensin-converting enzyme inhibitor induced small but significantly fewer (p < 0.05) changes in diastolic BP and heart rate. Treadmill exercise induced similar changes in systolic and diastolic BPs with both treatments compared with no treatment. The angiotensin-converting enzyme inhibitor appears to provide additional protection to that seen with β blockers during mental and static stressors by blunted changes in skin temperature and galvanic skin resistance.
