8-isoprostane, 6.03 ± 0.87 vs. 8.49 ± 0.52 µmol, p < 0.05 for nitrite/nitrate, and 0.44 ± 0.03 vs. 0.59 ± 0.04, p < 0.05 for oxidized/reduced glutathione ratio), nuclear factor kappa B activity (0.37 ± 0.09 vs. 0.60 ± 0.11, p < 0.05) and apoptosis rate (0.98 ± 0.28 vs. 1.63 ± 0.16, p < 0.05). Moreover, it improved left ventricular developed pressure (72.46 ± 8.16 vs. 52.01 ± 11.32 mm Hg, p < 0.05) and coronary flow (14.08 ± 1.09 vs. 11.75 ± 1.43 mL/ /min × g, p < 0.05). Conclusions: These beneficial cardioprotective observations suggest that treatment with resveratrol can potentially delay or attenuate the progression of diabetes-related cardiac complications.
