Epicardial adipose tissue and neural mechanisms of atrial fibrillation.

Echocardiographic Epicardial Adipose Tissue as a New Indicator of Cardiovascular Risk

Abstract Background and Purpose: Epicardial fat is the true visceral fat located around the heart, particularly around sub-epicardial coronary arteries that may locally interact and modulate the coronary arteries and myocardium through paracrine or vasocrine secretion of anti-inflammatory and proatherogenic cytokines. Most previous studies have used echocardiography and reported controversia...

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 ...

Epicardial adipose tissue and atrial fibrillation: The other side of the coin

Mathematical Modeling of Epicardial RF Ablation of Atrial Tissue with Overlying Epicardial Fat

The efficacy of treating atrial fibrillation by RF ablation on the epicardial surface is currently under question due to the presence of epicardial adipose tissue interposed between the ablation electrode and target site (atrial wall). The problem is probably caused by the electrical conductivity of the fat (0.02 S/m) being lower than that of the atrial tissue (0.4-0.6 S/m). Since our objective...

Comparison of Epicardial Adipose Tissue Fatty Acid Profile in Cardiovascular Disease Patients Diabetic and Non-Diabetic

ABSTRACT         Background and Objective: The relationship between diabetes mellitus and increased risk of cardiovascular diseases has been demonstrated. The aim of this study was to determine the fatty acid profile of epicardial adipose tissue in diabetic and non-diabetic patients with cardiovascular disease.       &nb...
