Epicardial adipose tissue (EAT) is a risk factor for cardiovascular diseases. Glucagon-like peptide 1 analogs (GLP-1A) may have beneficial cardiovascular effects and reduce EAT, possibly throughout targeting GLP-1 receptor (GLP-1R). Nevertheless, the role of EAT GLP-1R, GLP-2R and their interplay with EAT genes involved in adipogenesis and fatty acid (FA) metabolism are unknown. We analyzed whether EAT transcriptome is related to GLP-1R/GLP-2R gene expression, and GLP-1/GLP-2 plasma levels in coronary artery disease patients (CAD).

EAT was collected from 17 CAD patients undergoing CABG for microarray analysis of GLP-1R, GLP-2R and genes involved in FA metabolism and adipogenesis. EAT thickness was measured by echocardiography. GLP-1 and GLP-2 levels were quantified by ELISA in CAD and healthy subjects (CTR).

EAT GLP-1R was directly correlated …
