Abstract
BACKGROUND: Midterm effects of bariatric surgery on patients with obesity and hypertension remain uncertain. OBJECTIVE: To determine the 3-year effects of Roux-en-Y gastric bypass (RYGB) on blood pressure (BP) compared with medical therapy (MT) alone. DESIGN: Randomized clinical trial. (ClinicalTrials.gov: NCT01784848). SETTING: Investigator-initiated study at Heart Hospital (HCor), São Paulo, Brazil. PARTICIPANTS: were randomly assigned (1:1 ratio). INTERVENTION: RYGB plus MT or MT alone. MEASUREMENTS: The primary outcome was at least a 30% reduction in total number of antihypertensive medications while maintaining BP less than 140/90 mm Hg. Key secondary outcomes were number of antihypertensive medications, hypertension remission, and BP control according to current guidelines (<130/80 mm Hg). RESULTS: and 2 patients required reoperation. LIMITATION: Single-center, nonblinded trial. CONCLUSION: RYGB is an effective strategy for midterm BP control and hypertension remission, with fewer medications required in patients with hypertension and obesity.
