Insights
Catheter ablation (CA) significantly improves survival and reduces hospitalizations for patients with atrial fibrillation (AF) and heart failure with reduced ejection fraction (HFrEF). CA also enhances cardiac function, offering a disease-modifying therapy option.
Area of Science:
- Cardiology
- Electrophysiology
- Heart Failure Research
Background:
- Atrial fibrillation (AF) is prevalent in patients with heart failure with reduced ejection fraction (HFrEF).
- The optimal management strategy for AF in HFrEF remains a critical clinical question.
Purpose of the Study:
- To evaluate the comparative effectiveness of catheter ablation (CA) versus medical therapy for AF in HFrEF patients.
- To assess the impact on mortality, heart failure hospitalizations, and left ventricular ejection fraction (LVEF).
Main Methods:
- Systematic review and meta-analysis of 11 randomized controlled trials and derived studies.
- Searched PubMed, Embase, and Cochrane Library up to December 2025.
- Assessed risk of bias using Cochrane RoB 2.0 and certainty with GRADE.
Main Results:
- CA significantly reduced all-cause mortality (RR=0.61) and HF hospitalizations (RR=0.68).
- LVEF improved by a mean of 6.4% in the CA group.
- AF recurrence and quality of life outcomes favored CA.
Conclusions:
- Catheter ablation is a safe and effective therapy for HFrEF patients with AF.
- CA improves survival, reduces hospitalizations, and enhances cardiac function in this population.
- Supports CA as a disease-modifying treatment strategy for AF in HFrEF.
Abstract:
The aim is to evaluate the impact of catheter ablation (CA) versus medical therapy for atrial fibrillation (AF) in patients with heart failure with reduced ejection fraction (HFrEF), focusing on mortality, heart failure (HF) hospitalizations, and left ventricular ejection fraction (LVEF). We conducted a systematic review and meta-analysis of 11 randomized controlled trials and randomized controlled trial-derived studies comparing CA with medical therapy for AF patients with HFrEF. Databases including PubMed, Embase, and Cochrane Library were searched up to December 2025. Outcomes included all-cause mortality, HF hospitalizations, change in LVEF, AF recurrence, and quality of life. Risk of bias was assessed using the Cochrane RoB 2.0 tool, and GRADE (Grading of Recommendations Assessment, Development, and Evaluation) was used to evaluate certainty. A total of 11 studies comprising over 2100 patients were included. CA significantly reduced all-cause mortality [risk ratio = 0.61, 95% confidence interval (CI): 0.45-0.83] and HF hospitalizations (risk ratio = 0.68, 95% CI: 0.50-0.91). LVEF improved by a mean of 6.4% (95% CI: 4.2-8.7) in the ablation group. AF recurrence and quality of life also favored CA. Sensitivity analyses confirmed the robustness of findings. In patients with HFrEF and AF, CA significantly improves survival, reduces HF hospitalizations, and enhances cardiac function, supporting its role as a disease-modifying therapy.
