Rationale, Design, and Experiences from the Vanguard Phase of the Bariatric Surgery for the Reduction of Cardiovascular Events (BRAVE) Trial.

A large international trial is rigorously comparing weight-loss surgery to intensive medical care for people with obesity and heart disease, addressing a critical evidence gap.

BRAVE is an investigator-initiated, multicenter open-label RCT comparing sleeve gastrectomy/Roux-en-Y gastric bypass vs guideline-based medical management in adults with obesity plus established CVD, addressing a critical evidence gap where only observational data existed. The vanguard phase (200 participants across 17 centers in 4 countries) demonstrates feasibility and identifies practical implementation lessons before full-scale enrollment.

What the study was

Study design
Randomized controlled trial (design/vanguard report)
Population
Adults with obesity (BMI ≥35 or ≥30 with T2D/age>55) and high-risk CVD (prior MI, coronary intervention, HF, AF, cerebrovascular disease, or PAD); N=200 randomized at vanguard; 17 centers in Canada, Brazil, Italy, Spain
Sample size
200
Category
Prevention
Maturity
Potentially Practice-Changing
Journal
American Heart Journal

Why it surfaced

First large RCT design for bariatric surgery vs medical therapy in high-CVD-risk obesity; international multicenter; primary composite endpoint addresses major unmet evidence need; vanguard phase confirms feasibility.
