We sought to determine whether preoperative statin treatment is more effective in reducing, after cardiac surgery with cardiopulmonary bypass, systemic inflammatory response and myocardial damage markers in patients who have elevated preoperative interleukin-6 levels than in patients who have normal preoperative interleukin-6 levels.

The study involved a prospective cohort of 164 patients who underwent coronary and valvular surgery with cardiopulmonary bypass. There were 2 study groups: group A (n = 60), patients with elevated preoperative interleukin-6 levels; and group B (n = 104), patients with normal preoperative interleukin-6 levels. Each group was subdivided according to whether patients were (group 1) or were not (group 2) treated preoperatively with statins. Accordingly, the subdivided study groups were A1 (n = 40), A2 (n = 20), B1 (n = 56), and B2 (n = 48). The plasma levels of proinflammatory interleukin-6 were measured 1, 6, 24, and >72 hours after surgery.

The baseline, operative, and postoperative morbidity and mortality characteristics were similar in all groups. Group A1 had significantly lower levels of interleukin-6 and troponin I than did group A2 at all postoperative time points. Group B1 had significantly lower levels of interleukin-6 than did group B2 postoperatively. There were no significant differences in troponin I levels between groups B1 and B2.

We conclude that, in patients with preoperative activation of the inflammatory system, preoperative treatment with statins is associated with lower postoperative interleukin-6 and troponin I levels after cardiac surgery with cardiopulmonary bypass.
