OBJECTIVE: Off-pump coronary artery bypass grafting (OPCAB) may reduce the inflammatory response associated with cardiopulmonary bypass (CPB) and contribute to minimizing postoperative complications. Heparin-coated circuits and poly2methoxyethylacrylate (PMEA)-coated circuits were developed to reduce such complications. We compared the postoperative inflammatory response with or without CPB. METHODS: Eighteen consecutive patients undergoing isolated coronary artery bypass grafting (CABG) were divided into three groups: OPCAB group (n=6), heparin-coated circuits group (n=6), PMEA-coated circuits group (n=6). The plasma concentrations of the following inflammatory markers were measured: cytokines [interleukin (IL-10)], polymorphonuclear elastase (PMNE), coagulofibrinolytic factor [thrombin-antithrombin III complex (TAT)], complement factor (C3a). RESULTS: At the end of CPB, IL-10 and TAT concentrations were significantly different among the three groups (OPCAB group < PMEA-coated group < heparin-coated group). The PMNE concentration was significantly lower in the OPCAB group and the heparin-coated group as compared to the PMEA-coated group both at the end of CPB and 4 hours after CPB. C3a concentration was significantly lower in the OPCAB group than in the CPB groups at the end of CPB. Clinical variables did not differ significantly among the three groups. CONCLUSION: Off-pump CABG is associated with a reduction in the inflammatory response when compared with on-pump CABG, using either PMEA-coated or heparin-coated circuits.
