Figure 4.

Different measurements were performed in the systemic circulation. (A) Troponin was significantly higher in the closed chest group compared to open chest group. (B) Systemic leucocyte numbers were measured at baseline and different time-points during ischemia and reperfusion. (C) Systemic neutrophil numbers were measured at baseline and different time-points during ischemia and reperfusion. (D) Lipid peroxidation measured by malondialdehyde concentration in coronary sinus blood was not different between the open chest and closed chest group. TnI: troponin I; ng: nanogram; l: litre; ml: millilitre; nmol: nanomol; CC: closed chest; OC: open chest, *P < 0.05.
