Key result
Heart failure is linked to ~37% higher 1-year readmission for recurrent AF post-ablation.
Why the study?
Previous studies examined post-ablation complications and hospitalizations for AF recurrence, but many used patient data from before 2015.
Cohort (n=9,189)
Yes
Effect estimate: OR 1.365 (95% CI 1.169-1.595)
p-value: p=<0.05
May support closer post-ablation monitoring in HF and women; leaves open need for prospective validation.
Atrial fibrillation (AF) is the most common cardiac arrhythmia and is increasing in prevalence due to an aging population. Although medications for rhythm and rate control remain the first-line treatment options for many patients, difficulties can include arrhythmia relapse and drug side effects. Catheter ablation or radiofrequency is an alternative treatment modality that can isolate where ectopic arrhythmic sites originate. Several previous studies have examined post-ablation complications and hospitalization rates for arrhythmia recurrence. However, many of these studies used patient data from before 2015. We examined the following data using recent records: pre-procedural patient characteristics, rates of post-procedural hospitalizations with documented recurrence of AF, and patient risk factors associated with these recurrences.

Shah et al. (2021) conducted a cohort in Atrial Fibrillation (n=9,189). Catheter ablation was evaluated on 365-day readmission for atrial fibrillation recurrence (Heart failure predictor) (OR 1.365, 95% CI 1.169-1.595, p=<0.05). At 365 days post-catheter ablation for atrial fibrillation, 14.83% of patients were readmitted with recurrent AF, with heart failure (OR 1.365) and female gender (OR 1.229) identified as significant predictors.
