Patients with persistent atrial fibrillation and metabolic comorbidities have an altered inflammatory state of atrial epicardial adipose tissue, which is linked to CT-attenuation

Patients with persistent versus paroxysmal AF exhibited increased EAT neutrophils, which is reflected by CT-EAT-attenuation. Those with AF recurrence, hypertension and diabetes had adipocyte hypertrophy which may imply a common mechanism underlying these conditions.
