Acute Hyperglycemia Abolishes Ischemic Preconditioning by Inhibiting Akt Phosphorylation: Normalizing Blood Glucose before Ischemia Restores Ischemic Preconditioning
Figure 4
The cardioprotective effect of ischemic preconditioning disappears in HG mice, but can be recovered by normalizing blood glucose levels with insulin prior to ischemia.
