Changes in: A rate-pressure product (RPP); B peak rate of contraction (+dP/dt); C peak rate of relaxation (−dP/dt) and D left ventricular end-diastolic pressure (LVEDP) due to ischemia-reperfusion in control and postconditioned hearts from fed and fasted rats. Values are expressed as percentages of the respective basal values at the end of the 25-min equilibration period. Open symbols fed hearts. Filled symbols fasted hearts. Squares control hearts. Triangles postconditioned hearts. Values are mean ± SEM (n = 8) A, B, C: a, p < 0.01 versus control fed, b, p < 0.05 versus postconditioned fasted, c, p < 0.05 versus postconditioned fed, d, p < 0.01 versus postconditioned fasted, e, p < 0.01 versus postconditioned fed. D a, p < 0.05 versus control fasted, b, p < 0.05 versus postconditioned fed., c, p < 0.05 versus postconditioned fasted
