Association of Epicardial Adipose Tissue With Bradyarrhythmias: A Matched Case-Control Study.

ABSTRACT:

Background

Epicardial adipose tissue (EAT) is implicated in exerting potential proarrhythmic effects. The relationship between EAT and tachyarrhythmias is well documented. However, the connection between EAT and bradyarrhythmias has not been comprehensively explored. This study aimed to investigate the association between EAT and bradyarrhythmias.

Methods

We retrospectively quantified the volume and density of EAT using chest computed tomography scans from patients with bradyarrhythmias and case-matched controls. Measurements were obtained through manual pericardial contour tracing with a standardized Hounsfield unit threshold of -200 to -50 Hounsfield units.

Results

A total of 652 patients were included, comprising 326 patients with bradyarrhythmias (age 74.00 [inter
