Key result

Aggressive modification of multiple risk factors is recommended to reduce AF recurrence after catheter ablation.

Why the study?

Catheter ablation is increasingly used for rhythm control in atrial fibrillation, but post-procedure recurrence remains high.

Does periablation risk-factor modification reduce recurrent atrial fibrillation in patients with atrial fibrillation undergoing catheter ablation?

Structured PICO

Does periablation risk-factor modification reduce recurrent atrial fibrillation in patients with atrial fibrillation undergoing catheter ablation?

P

Population

Patients with atrial fibrillation undergoing catheter ablation

I

Intervention

Periablation risk-factor modification (including management of hypertension, diabetes, obesity, obstructive sleep apnea, MASLD, smoking, alcohol consumption, and physical inactivity)

O

Outcome

Recurrent atrial fibrillation after catheter ablation

Comprehensive periprocedural risk-factor modification, including weight loss, CPAP for OSA, and glycemic/blood pressure control, is recommended to reduce the high recurrence rate of atrial fibrillation after catheter ablation.

Limitations

Evidence specifically in patients with atrial fibrillation undergoing catheter ablation is scarce
Many cited studies are observational or retrospective, subject to selection bias
Lack of randomized controlled trials for several risk factor interventions in the periablation setting

Implication

Supports multifactorial risk-factor modification to curb post-ablation AF recurrence; leaves open definitive evidence from randomized trials.

Abstract

More and more patients with atrial fibrillation are undergoing catheter ablation as a rhythm-control strategy, but the recurrence rate after the procedure is high. A wide array of risk factors contribute to the pathogenesis of atrial fibrillation, including hypertension, diabetes mellitus, dyslipidemia, obesity, obstructive sleep apnea, metabolic dysfunction-associated steatotic liver disease (MASLD), smoking, alcohol consumption, and physical inactivity. This review summarizes the emerging evidence for periablation risk-factor modification to optimize postablation outcomes.

Cite This Study

Hartnett et al. (2025) conducted a review in Atrial fibrillation. Risk-factor modification (weight loss, CPAP, glycemic and blood pressure control) vs. Usual care or no risk-factor modification was evaluated on Recurrent atrial fibrillation after catheter ablation. Simultaneous aggressive modification of multiple risk factors, including obesity, sleep apnea, and diabetes, is recommended to reduce the high recurrence rate of atrial fibrillation after ablation.
