CPB: Cardiopulmonary bypass, IL: Interleukin; Mon1, CD14++CD16− monocytes; Mon2, CD14++CD16+ monocytes; Mon3, CD14−CD16+ monocytes.

Days of Hospitalization: Overall time of stay in hospital; Fluid balance: post-OP – Fluid balance ad admission at the ICU (measured since arriving at the operation theater), day 1 and day 4: fluid balance within the last 24 hours.
