Asthma is associated with higher recurrence rates of atrial fibrillation after catheter ablation
Authors' conclusion
Patients with AF and asthma, particularly those with severe asthma, were more likely than patients with AF but without asthma to have AF recurrence after ablation. Patients with AF and severe asthma were also more likely to have severe left atrial enlargement, a known predictor of recurrence after ablation.

Predictors of recurrence (multivariate)
- Persistent AF and beta-blocker use associated with recurrence
Safety
- Asthma patients not more likely to experience adverse outcomes
