Epicardial fat is the true visceral fat located around the heart, particularly around sub epicardial coronary arteries . Epicardial and intra-abdominal fat derive from brown adipose tissue within embryogenesis . Because of the close anatomical relationship to the heart, and the absence of fascial boundaries, epicardial adipose tissue (EAT) may locally interact and modulate the coronary arteries and myocardium through paracrine or vasocrine secretion of anti-inflammatory and proatherogenic cytokines . Therefore, it is meaningful to explore its connection with CAD.
