Although enhanced cGMP signaling can prevent hypertrophy, mechanisms underlying this cardioprotective effect are not well understood. In this study, we assessed the potential involvement of alterations in myocardial energy substrate metabolism, a parameter known to be determinant in the development of hypertrophy. We used mice overexpressing a constitutively active soluble guanylate cyclase in a cardiomyocyte-specific manner (GC+/0) and ex vivo heart perfusion at physiological workload with 13C-labeled substrates. Compared to controls, hearts from GC+/0 mice displayed a 38±9% lower contribution of exogenous fatty acids to acetyl-CoA formation, while that of carbohydrates remained unchanged despite a two-fold increase in glycolysis. The lowe...
