Key result
Early rhythm control via ablation may reduce mortality and HF hospitalization in concurrent AF and HF.
Why the study?
AF and CHF frequently coexist with worse prognosis than either condition alone, forming a self-reinforcing cycle where the optimal management strategy remains an active question.
Does early rhythm control reduce mortality and heart-failure hospitalisation in patients with coexisting atrial fibrillation and congestive heart failure?
Does early rhythm control reduce mortality and heart-failure hospitalisation in patients with coexisting atrial fibrillation and congestive heart failure?
This review argues that early rhythm control, particularly via catheter ablation, is superior to rate control for improving outcomes in patients with concurrent atrial fibrillation and heart failure.
Advocates early rhythm control in AF with HF; challenges negative AFFIRM/AF-CHF drug findings while reinforcing 2023 Class 1 guideline.
Atrial fibrillation (AF) and congestive heart failure (CHF) frequently coexist, and their combination carries a worse prognosis than either condition alone. This thesis argues that AF and CHF form a single, self-reinforcing pathophysiological cycle in which each disease provokes and worsens the other, so the optimal strategy is not to tolerate the arrhythmia through rate control but to interrupt the cycle early through rhythm control — principally catheter ablation — on a foundation of guideline-directed medical therapy, anticoagulation, and risk-factor modification. Early drug trials (AFFIRM, AF-CHF) showed no benefit from pharmacological rhythm control, but the CASTLE-AF and CASTLE-HTx trials later demonstrated that catheter ablation reduces mortality and heart-failure hospitalisation in patients with reduced ejection fraction — evidence now reflected in the 2023 ACC/AHA/ACCP/HRS Class 1 recommendation. Interrupting the cycle early, rather than managing its consequences late, is the most promising path to better outcomes.

Н.В. et al. (2026) conducted a review in Atrial fibrillation and congestive heart failure. Early rhythm control (principally catheter ablation) vs. Rate control was evaluated. Early rhythm control, principally catheter ablation, is argued to reduce mortality and heart-failure hospitalization in patients with coexisting atrial fibrillation and heart failure.
