From: New technique of local ischemic preconditioning induction without repetitive aortic cross-clamping in cardiac surgery

Time point Control (n = 30) Perfusion (n = 30) IP (n = 30)
Before surgery 0.004 ± 0.008 0.005 ± 0.011 0.010 ± 0.012
2 h after surgery 0.84 ± 0.79 1.61 ± 1.68 1.18 ± 0.77

12 h after surgery 1.52 ± 0.62 1.57 ± 0.89 1.56 ± 0.61
24 h after surgery 1.67 ± 1.03 1.92 ± 2.45 1.17 ± 0.56*
48 h after surgery 0.97 ± 0.61 1.32 ± 1.83 0.75 ± 0.42
