FIGURE 4:

Urinary NOx (nitrite + nitrate) excretion (A; sham n = 5, AI n = 5), cardiac NOx (B; sham n = 7, AI n = 7), as well as a representative western blot and quantification of cardiac eNOS (C; sham n = 7, AI n = 6) in the sham and AI animals. Systemic nitric oxide and cardiac nitric oxide production were significantly reduced in the AI animals relative to the sham animals. Values are mean ± SEM; eNOS, endothelial nitric oxide synthase; AI, 5/6 ablation–infarction animals; *P < 0.05 versus sham.
