PURPOSE: 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.
MATERIAL/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.
