Why CABANA-HF?

Heart failure with preserved ejection fraction (HFpEF) and atrial fibrillation (AF) together affect approximately 1.2 million patients in the United States. These patients face a 25–60% event rate at five years, yet there are no completed randomized clinical trials evaluating AF ablation vs medical therapy in this high-risk population.

Modern Therapy

All participants receive contemporary guideline-directed medical therapy including SGLT2 inhibitors, MRAs, ARNI, and GLP1-RA alongside rhythm-control strategies.

Global Impact

With over 120 sites across 12 countries, CABANA-HF will generate evidence applicable to diverse patient populations worldwide.

Study Design

Two Randomized Arms

Patients are randomized 1:1 to one of two treatment strategies, both anchored in contemporary guideline-directed medical therapy for HFpEF.

Ablation + GDMT

Catheter ablation of atrial fibrillation combined with comprehensive guideline-directed medical therapy for HFpEF. The ablation strategy targets pulmonary vein isolation with additional lesion sets at the operator's discretion.

GDMT Alone

Optimized guideline-directed medical therapy for HFpEF with rate or rhythm control for atrial fibrillation per current ACC/AHA/ESC guidelines. Crossover to ablation is permitted after a prespecified period if clinically indicated.

Primary Endpoint

Composite of cardiovascular mortality or significant worsening heart failure events.
