Popis: Objectives: Adipose tissue produces a number of adipokines that have metabolic effect. Visfatin is a recently discovered adipokine whose concentration in plasma increases in obesity. It is also a proinflammatory mediator that promotes atherosclerosis and plays a role in plaque destabilization. The aim of this study was to evaluate an assay for the determination of visfatin in human plasma and to investigate its clinical relevance as a marker of acute coronary syndrome (ACS) in a young population (Men under 45 y, Women under 55 y). Design and Methods. We clinically tested a sandwich ELISA assay in young individuals with acute myocardial infarction (n=36) vs. a control group (n=21). The control sample was a healthy proband without inflammation, hepatic or renal injury and under 55 years of age. Results: Visfatin in plasma was able to differentiate the control group from young patients with acute myocardial infarction (5 vs. 27 ng/L). Visfatin in the plasma of acute myocardial infarction (AMI) probands, correlated in individuals with acute coronary syndrome was related to plasma glucose (r=0.47; P=0.01), type 2 diabetes mellitus (r=0.65; P=0.01), plasma creatinine concentration (r=0.3, P=0.02), hsCRP (r=0.29; P=0.03), BMI values (r=0.18; P=0.04), triglycerides (r=0.5; P=0.01) and NT-proBNP (r=0.21; P=0.04). In healthy subjects, these relations were not found. ROC analysis: visfatin cut-off concentration was 20 ng/L with a sensitivity of 84% and a specificity of 90%. The area under the curve (AUC) of cTNI was 0.96, the AUC of visfatin was 0.96. Thus, there was no difference. Conclusion: We conclude that visfatin in serum may be a new independent potential marker of AMI.
