title: Serum adiponectin and markers of endothelial dysfunction in stable angina pectoris patients undergoing coronary artery bypass grafting (CABG).
abstract: OBJECTIVE
  It has been established that endothelial dysfunction (ED) occurs after coronary artery bypass grafting (CABG). The aim of the study was to assess whether adiponectin may act as a novel marker of ED and its potential relations with new markers of ED: novel cell adhesion molecule CD146, a natural anti-thrombin glycoprotein - thrombomodulin (TM) and the well-established ED marker - Von Willebrand factor (VWF) in coronary artery disease (CAD) patients undergoing CABG.
  
  
  METHODS
  45 CAD patients undergoing elective CABG were included in the study.
  
  
  RESULTS
  In the study group the concentration of adiponectin and CD146 before the surgery were significantly lower than in the control group - 6.06 μg/ml ± 3.06 vs. 19.0 μg/ml ± 6.4 and 303.2 ng/ml ± 28.7 vs. 328.1 ng/ml ± 22.6 (p<0.05). Significant increase of adiponectin and CD146 concentration 3 months after CABG vs. before the surgery was found. Adiponectin concentration 3 months after CABG correlated with VWF, TM, CD146, and a number of grafts. CD146 before and 3 months after CABG correlated significantly with adiponectin, VWF activity as well as the statins therapy after the surgery.
  
  
  CONCLUSIONS
  In CAD patients undergoing CABG new markers of endothelial cell dysfunction as adiponectin and CD146 are significantly lower compared to healthy volunteers. Significant increase in adiponectin and CD146 concentration 3 months after CABG vs. before the surgery was found. However adiponectin concentrations 3 months after CABG were still significantly lower compared to healthy individuals, whereas CD146 concentration returned to the values comparable to the control.
