Left Atrial Epicardial Adiposity and Atrial Fibrillation

Left atrial epicardial adiposity and atrial fibrillation.

BACKGROUND Atrial fibrillation (AF) has been linked to inflammatory factors and obesity. Epicardial fat is a source of several inflammatory mediators related to the development of coronary artery disease. We hypothesized that periatrial fat may have a similar role in the development of AF. METHODS AND RESULTS Left atrium (LA) epicardial fat pad thickness was measured in consecutive cardiac CT...

Associations of Epicardial, Abdominal, and Overall Adiposity With Atrial Fibrillation.

BACKGROUND Although adiposity is increasingly recognized as a risk factor for atrial fibrillation (AF), the importance of epicardial fat compared with other adipose tissue depots remains uncertain. We sought to characterize and compare the associations of AF with epicardial fat and measures of abdominal and overall adiposity. METHODS AND RESULTS We conducted a meta-analysis of 63 observationa...

Epicardial Fat and Atrial Fibrillation: A Review.

Atrial fibrillation (AF) is a progressive disorder that increases with age. Obesity is an important risk factor for AF. Pericardial fat is an active adipose tissue in close proximity to the heart and has been shown to be a risk factor for structural as well as coronary artery disease independent of body mass index. Recent studies suggest a role of epicardial fat in atrial remodeling as well as ...

Congenital Left Atrial Bands with Atrial Fibrillation

Epicardial adipose tissue and atrial fibrillation.

Atrial fibrillation (AF) is the most frequent cardiac arrhythmia in clinical practice. AF is often associated with profound functional and structural alterations of the atrial myocardium that compose its substrate. Recently, a relationship between the thickness of epicardial adipose tissue (EAT) and the incidence and severity of AF has been reported. Adipose tissue is a biologically active orga...
