Key result
Higher total epicardial fat tissue volume was associated with atrial fibrillation recurrence after ablation (SMD 1.017; 95% CI 0.748-1.286).
Why the study?
Although an association between epicardial fat tissue and AF is established, whether EFT is associated with post-ablation AF recurrence remains unclear.
Is epicardial fat tissue associated with atrial fibrillation recurrence after ablation?
Meta-Analysis
Is epicardial fat tissue associated with atrial fibrillation recurrence after ablation?
Standardized Mean Difference: 1.017 (95% CI 0.748–1.286)
Increased total and left atrial epicardial fat tissue volumes, as well as thickness, are significantly associated with a higher risk of atrial fibrillation recurrence following ablation.
No takes yet. Share an insight, caveat, or question.
May refine pre-ablation AF recurrence risk stratification; extends observational evidence via pooled quantification.
Shamloo et al. (2019) conducted a meta-analysis in Atrial fibrillation recurrence after ablation. Epicardial fat tissue (EFT) vs. Patients without AF recurrence was evaluated on Total EFT volume difference between patients with and without AF recurrence (SMD 1.017, 95% CI 0.748-1.286). Higher total epicardial fat tissue volume was associated with atrial fibrillation recurrence after ablation (SMD 1.017; 95% CI 0.748-1.286).
