| Abstract [eng] |
The endothelial cell damage/dysfunction is associated with increased expression of adhesion molecules, synthesis of proinflammatory, prothrombotic factors and abnormal modulation of vascular tone. A growing body of evidence suggests that endothelial dysfunction is associated with future cardiovascular events including cardiac death, myocardial infarction and the need for revascularization procedures. The aim of the study was to evaluate the impact of markers of endothelial damage as predictors of cardiovascular events after on-pump coronary artery bypass grafting surgery. We found that higher concentrations preoperatively of hs-CRP and sVCAM-1 were independent markers for higher risk of cardiovascular events after coronary artery bypass grafting surgery. Concentration of hs-CRP, sVCAM-1 and sICAM-1 increased significantly after on-pump coronary artery bypass grafting surgery compared to preoperative level. However correlation between the duration of aortic cross-clamp, cardiopulmonary bypass or surgery and markers of endothelial damage was not found. Correlation between postoperative concentration of hs-CRP, sVCAM-1 and sICAM-1 and risk for cardiovascular events after coronary artery bypass grafting surgery was not found. |
