BACKGROUND: It has been suggested that off-pump coronary artery bypass grafting (CABG) surgery reduces myocardial ischemia-reperfusion injury, postoperative systemic inflammatory response, and oxidative stress. The aim of this study was to measure serum malondialdehyde (MDA), high-sensitivity C-reactive protein (hs-CRP), M30, and M65 levels and to investigate the relationship between M30 levels and oxidative stress and inflammation in patients undergoing on-and off-pump CABG surgery. METHODS:Fifty patients were randomly assigned to on-pump or off-pump CABG surgery (25 patients off-pump and 25 on-pump CABG surgery), and blood samples were collected prior to surgery, and 30 minutes, 60 minutes, 6 hours, and 24 hours after CABG surgery. RESULTS: Compared to the on-pump group, serum MDA levels at 30 minutes, 60 minutes, 6 hours, and 24 hours after the CABG surgery were significantly lower in the off-pump group (P=.001, P=.001, P=.001, and P=.001, respectively). Serum M30 levels were found to be elevated in both groups, returning to baseline at 24 hours. When compared to baseline, the hs-CRP level reached its peak at 24 hours at 13.28±5.32 mg/dL in the on-pump group, and 15.44±4.02 mg/dL in the off-pump group. CONCLUSION: CABG surgery is associated with an increase in inflammatory markers and serum M30 levels, indicating epithelial/endothelial apoptosis in the early period.
