Fig 1 Changes in myocardial tissue oxygen saturation (SO2). ∗p < 0.05 compared with group 1. (O = coronary occlusion; R = coronary reperfusion.) The Annals of Thoracic Surgery 2000 69, 1806-1810DOI: (10.1016/S0003-4975(00)01143-7)
Fig 2 Changes in myocardial tissue hemoglobin plus myoglobin (Hb) concentration. ∗p < 0.001 compared with group 1; †p < 0.05 compared with group 2; ‡p < 0.05 compared with groups 1 and 2. (O = coronary occlusion; R = coronary reperfusion.) The Annals of Thoracic Surgery 2000 69, 1806-1810DOI: (10.1016/S0003-4975(00)01143-7)
Fig 3 Serum troponin-T levels before coronary occlusion (pre) and after 3-hour reperfusion (post). ∗p < 0.05 compared with group 1; †p < 0.001 compared with group 1. Differences between postreperfusion troponin-T levels of groups 2 and 3 did not reach statistical significance. The Annals of Thoracic Surgery 2000 69, 1806-1810DOI: (10.1016/S0003-4975(00)01143-7)
