Postoperative atrial fibrillation following cardiac surgery is associated with pre-existing inflammatory dysregulation in epicardial adipose tissue. Insights from transcriptomic analysis

Postoperative atrial fibrillation (POAF) is a common arrhythmia occurring in up to one third of patients after cardiac surgery. POAF is associated with poor outcome and long-term atrial fibrillation recurrence. Recent studies identified epicardial adipose tissue as a potential actor in atrial fibrillation pathophysiology. We aimed at investigating whether POAF was associated with a specific pre-operative phenotype in epicardial adipose tissue...
