The plasma levels of myocardial troponin (cTnT) for the four groups of animals at the four time points: t
1, 30 min after stabilization; t
2, immediately before the start of coronary artery occlusion; t
3, 60 min after the start of coronary artery occlusion; and t
4, 120 min after the start of reperfusion. Data are mean±SD of 8 rats per group. *
