Blood samples were withdrawn prior to surgery (T1) and then 4 hours (T2), 24 hours (T3), and 36 hours (T4) after CPB. Plasma levels of interleukin (IL)-6, IL-10, creatine kinase isoenzyme MB (CK-MB), cardiac troponin-t (cTnT), and blood glucose as well as neutrophil counts were measured at each sampling time. <br /><strong>Results</strong>: A comparison of patients between both groups revealed significantly high levels of IL-6 in the control group at T2, T3, and T4 with respect to T1 (T2: P &lt; .001; T3: <br />P &lt; .001; T4: P &lt; .001). IL-10 levels were significantly higher in the study group at T2 compared with the control group <br />(P = .007). CK-MB levels were significantly lower in the study group than in the control group at T4 (P = .001). The increase of cTnT was higher in the control group at T3 and T4 compared with the study group (T3: P = .002; T4: P = .001).<br /><strong>Conclusions</strong>: This study demonstrates that methylprednisolone is effective for ensuring better myocardial protection during cardiac surgery by suppressing the inflammatory response via decreasing the levels of IL-6 and by increasing anti-inflammatory activity through IL-10.<br /><br />}, number={4}, journal={The Heart Surgery Forum}, author={Demir, Tolga and Ergenoglu, Mehmet Umit and Demir, Hale Bolgi and Tanrikulu, Nursen and Sahin, Mazlum and Gok, Emre and Korkut, Kubilay and Demirsoy, Ergun}, year={2015}, month={Aug.}, pages={E171-E177} }
