Why the study?
The study aimed to evaluate the reliability of cardiac CT EAT volume measurements using adjusted thresholds and analyze the relationship of EAT distribution and volume with clinical presentation in AF patients compared to healthy controls.
This study aims to evaluate the reliability of cardiac CT for measuring epicardial adipose tissue and its association with atrial fibrillation compared to healthy controls.

CT-based EAT quantification feasible in AF; leaves open its clinical or prognostic utility.
he association between the presence of atrial fibrillation (AF) and an increased epicardial adipose tissue (EAT) volume has been established, linking a certain amount of probable and possible pathophysiologic mechanisms that could contribute to promoting arrhythmogenesis. In the present study, we aimed to assess the reliability of EAT volume measurements on cardiac CT with adjusted thresholds for fat detection and analyze the association of EAT distribution and volume with the clinical presentation in AF patients in comparison with healthy individuals. Materials and methods. 45 consecutive AF patients (mean age 55.2 10.3 years, mean AF duration 49.0 38.4 months) with different AF patterns scheduled for an initial ablation for AF and 15 healthy individuals (mean age 36.2 12.6 years) without a history or symptoms of cardiovascular diseases were included. The total, as well as periatrial EAT volumes, were obtained on cardiac CT datasets with adjusted thresholds for fat detection.
