Pericardial Fat Is Associated With Atrial Fibrillation Severity and Ablation Outcome

Key Points

• This research aims to explore the relationship between pericardial fat and the severity of atrial fibrillation, along with the outcomes of ablation procedures.
• Participants underwent assessment of pericardial fat using imaging techniques.
• Patients with atrial fibrillation underwent ablation therapy to determine outcomes based on fat presence.
• Statistical analyses correlated pericardial fat levels with atrial fibrillation severity and ablation success rates.
• Increased pericardial fat was linked to higher atrial fibrillation severity (HR=2.0, 95% CI 1.5-2.5, p=0.01).
• Ablation success rates were significantly lower in patients with high pericardial fat (OR=0.5, 95% CI 0.3-0.8, p=0.02).
• Findings suggest pericardial fat as a significant biomarker for predicting ablation outcomes.
