Nesfatin 1: a promising biomarker predicting successful reperfusion after coronary artery bypass surgery

Nesfatin-1 is an antiiflammatory, antiapoptotic, and anorexigenic peptide that has many roles in cardiomyocyte metabolism and viability. Inflammation plays an important role in the pathogenesis of atherosclerosis. In this study, we aimed to evaluate the alterations in serum nesfatin-1 levels of the patients undergoing coronary artery bypass operation due to atherosclerotic coronary artery disease.

The study included 49 patients (30 men, 19 women) undergoing coronary artery bypass surgery. Serum nesfatin-1 levels were measured from venous blood samples of the patients collected before and three months after the operation. The relationship of nesfatin-1 levels with accompanying conditions was also analyzed.

Nesfatin-1 levels at third month, postoperatively, were significantly higher than preoperative nesfatin-1 levels of the patients (41.94±13.90 pg/ml and 27.06±8.01pg/ml, respectively; p<0.001). Both preoperative and postoperative nesfatin-1 levels were negatively correlated with age (p<0.001). The postoperative increase in nesfatin-1 levels was significantly higher in diabetic patients than in nondiabetic patients (p<0.001).

This study revealed that serum nesfatin-1 levels increased significantly in patients undergoing coronary artery bypass operation. Nesfatin-1 level may have a role in assessing myocardial perfusion during the follow-up of these patients (Tab. 4, Fig. 4, Ref. 25).
