Figure 1).

Effect of acute (one-week) streptozotocin-induced diabetes (D) and ischemic preconditioning (I-PC) in the nondiabetic myocardium on the size of myocardial infarction (IS) (A), number of premature ventricular complexes (PVC) (B), severity of ischemia-induced ventricular arrhythmias (C) and postischemic recovery of left ventricular developed pressure (LVDP) (D) in Langendorff-perfused rat hearts. IS is expressed as a percentage of the area at risk (AR). LVDP recovery is expressed as a percentage of preischemic values. Data are presented as mean ± SEM from 10 to 12 hearts per group. *P<0.05 versus nondiabetic control (C) group
