Abstract

Background: In hypertension, β-blockers have a high rate of nonadherence to treatment likely because of fatigue.

Methods: We evaluate daily physical activity and maximal exercise performance in 56 patients with hypertension (grades I-II), with and without β-blockers (bisoprolol 10 mg or atenolol 100 mg) added to standard treatment; 48 patients completed the study. Study tests were performed after 8 weeks of antihypertensive therapy without β blockers and after the following 8 weeks with β-blockers.

Results: No significant differences between β-blockers were observed. At office measurement, β-blockers decreased heart rate (HR) from 78 ± 9 to 62 ± 7 bpm (P < 0.01) and SBP from 133 ± 13 to 125 ± 12 mmHg (P < 0.01). No significant changes were observed for DBP. Conversely, at ambulatory pressure monitoring DBP but not SBP decreased with β-blockers (mean-24-h DBP 77 ± 8 vs. 74 ± 7 mmHg, P < 0.01). An overall reduction of daily activities and of estimated kilocalories consumption was observed as measured by a portable armband device. Of note, time with activity more than 3 METS was reduced by β-blockers from 148.1 (83-201) to 117.9 (82-189) min (P < 0.01). Cardiopulmonary exercise (CPE) showed a preserved exercise performance unaffected by β-blockers.

Conclusion: In hypertension, β-blocker treatment is associated to reduction of daily physical activity but not of maximal exercise performance.
