Abstract | AIM:
Cardiopulmonary bypass is associated with a complex systemic inflammatory response and the extent of their increase has been correlated with the development of postoperative complications. Recent studies suggest that treatment with statins is associated with a significant and marked decrease in inflammation-associated variables such as cytokines. Therefore, we investigated the effects of preoperative simvastatin treatment on systemic inflammatory response and perioperative morbidity after cardiopulmonary bypass. METHODS: A prospective, randomized study, was designed. Forty-four subjects undergoing elective coronary artery bypass grafting who fulfilled the inclusion criteria were randomized to treatment with simvastatin (20 mg/day, group A, N. 22) or control (group B, N. 22) before surgery. Plasma levels of interleukins (IL-6, IL-8, TNF-alpha), and systemic inflammatory response score (SIRS) were measured during the surgical intervention and over the following 48 postoperative hours. Cytokine levels were measured by enzyme-linked assays from plasma samples obtained at specific time points pre- and post-operation. RESULTS: In both groups the serum levels of the proinflammatory cytokines (IL-6, IL-8, TNF-alpha), and leukocytes, and the SIRS score increased significantly over the baseline, though no significant differences were observed between the two groups. The preoperative and postoperative course did not differ between both groups. CONCLUSIONS:
