Body mass index, acute atrial fibrillation termination, and long-term recurrence after catheter ablation for persistent atrial fibrillation: insights from a large contemporary cohort

Listen to this summary

The authors aimed to investigate the relationship between body mass index (BMI) and both the acute termination of atrial fibrillation (AF) and the long-term recurrence of atrial arrhythmia following catheter ablation for persistent AF. They found that higher BMI was associated with lower rates of acute AF termination and increased risks of long-term recurrence, suggesting that BMI could be a valuable marker for preprocedural risk assessment in patients undergoing this treatment.
