A recent publication by Lopes et al (2021) in JAMA suggests that the addition of a structured aerobic exercise intervention to optimal medical therapy improves blood pressure control in resistant hypertension.
The Exercise Training in the Treatment of Resistant Hypertension (EnRicH) trial is a prospective, 2-center, single-blinded randomised trial that was performed in Portugal from March 2017 to December 2019. 60 participants, aged 40-75 years, with a diagnosis of resistant hypertension were enrolled. They were then randomly assigned in a 1:1 ratio to a 12-week moderate-intensity aerobic exercise training program, or ‘usual care’ control group. The primary efficacy measure was a 24-hour ambulatory systolic blood pressure change from baseline.53 patients completed the study (26 in exercise group, 27 in control group). In the exercise group, 24-hour ambulatory systolic BP was reduced by 7.1 mm Hg (95% CI, −12.8 to −1.4; P = .02). Clinic systolic BP (−10.0 mm Hg; 95% CI, −17.6 to −2.5; P = .01) and cardiorespiratory fitness (5.05 mL/kg per minute of oxygen consumption; 95% CI, 3.5 to 6.6; P < .001) also improved in the exercise group compared with the control group.
‘These findings provide clinicians with evidence to embrace moderate-intensity aerobic exercise as a standard coadjutant therapy targeting this patient population.’ The authors state.
