Heart function in the Langendorff preparation. Adult and aged isolated rat hearts were challenged with increasing concentrations of isoproterenol. Contractility was evaluated as developed pressure, dP/dtmax and lusitropy as dP/dtmin. Aged hearts were treated with NOX inhibitors apocynin (100 µmol/L) or VAS2870 (20 µmol/L). N = 5 hearts each group. Values are presented as mean ± standard error; n = 5. * p < 0.05, ** p < 0.01 and *** p < 0.001 vs. corresponding control.
