Impact of hyperglycemia on myocardial ischemia–reperfusion susceptibility and ischemic preconditioning in hearts from rats with type 2 diabetes

Infarct size (%) at the end of 40 min of global ischemia and 120 min of reperfusion in diabetic (DM) Control, Non-DM Control, DM ischemic preconditioned (IPC) and Non-DM-IPC hearts. Perfusion glucose level were 11 mmol/L and 22 mmol/L. *p？<？0.05; **p？<？0.01. Mean？±？SE
