Epicardial adipose tissue features as a biomarker and therapeutic target in coronary artery disease
Abstract This study aimed to examine the interplay between epicardial adipose tissue (EAT) features, macrophage polarization, and the cytokines Resistin and Apelin in the context of coronary artery disease (CAD). Using a case-control design with 21 CAD and 20 non-CAD individuals, the study collected...

| Summary: | Abstract This study aimed to examine the interplay between epicardial adipose tissue (EAT) features, macrophage polarization, and the cytokines Resistin and Apelin in the context of coronary artery disease (CAD). Using a case-control design with 21 CAD and 20 non-CAD individuals, the study collected demographic data, cardiovascular risk factors, and medical histories. Metabolic risk factors were assessed through laboratory tests, and CAD presence was confirmed by imaging studies. Detailed measurements of epicardial adipose characteristics were obtained through CT scans. Blood samples were analyzed for Resistin and Apelin levels, and tissue samples from EAT for macrophage polarization. The results revealed no significant differences in EAT volume and density between CAD and non-CAD groups, but the CAD group exhibited a significantly higher Calcium score. Apelin and Resistin mRNA expression levels in the right ventricular epicardial and atrioventricular fat tissue showed significantly lower Apelin and higher Resistin levels in CAD patients. CD206 expression levels in EAT were substantially lower in the CAD group, while CD11c expression levels were significantly higher. The CAD group exhibited a significantly higher CD11c/CD206 ratio in adipose tissue macrophages. This investigation highlights the significance of molecular characteristics of EAT in CAD development. While no significant differences were found in EAT volume and density, lower Apelin and higher Resistin mRNA expression in CAD patients’ right ventricular fat tissue were observed. Changes in macrophage polarization markers, lower CD206 and higher CD11c, along with a higher CD11c/CD206 ratio in the macrophages of CAD patients have been shown in two investigated regions of EAT. |
