It is evident that coronary artery disease (CAD) is closely associated with abnormal glucose and lipid metabolism. Notably, dysregulation of inflammatory pathways and immune system also contribute to CAD development. Recently, it has been suggested that visfatin, a proinflammatory adipocytokine, may be involved in several inflammatory and metabolic diseases. In this study, we evaluated the serum visfatin levels and its mRNA expression in peripheral blood mononuclear cells (PBMCs) from CAD patients compared with control subjects. We also studied the correlation between visfatin gene expression and serum levels with clinical and metabolic parameters. This study was conducted on 56 male patients with CAD confirmed by angiography and 30 healthy men as controls. CAD severity was determined based on the number of vessels. Study of gene expression in PBMCs was performed using real time-PCR, and serum levels of visfatin and 25-hydroxyvitamin D were measured by ELISA. We found that serum visfatin levels and its gene expression in PBMCs were increased in patients with CAD compared with the control group (p=0.027 and p=0.016, respectively). Also, visfatin gene expression was positively correlated with visfatin levels and both these variables had a strong positive correlation with the severity of CAD. It appears that elevated mRNA expression and circulating level of visfatin might be of relevance to the pathogenesis and severity of CAD. However, further studies are necessary to better clarify the associations between visfatin and CAD.
