Effect of acute ischemic preconditioning on postischemic recovery of left ventricular diastolic pressure (LVDP) (A), duration of ventricular tachycardia (VT) (B) and size of infarction (C) in Langendorff-perfused rat hearts subjected to 30 min of global ischemia and 2 h reperfusion. C Nonpreconditioned normotensive and hypertensive controls; PC Preconditioned hearts. Data presented as means ± SEM of eight to 10 hearts per group. *P<0.05 versus normotensive rats; †P<0.05 versus respective nonpreconditioned control rats
