like the myopathic hearts the re-equilibrated acidotic hearts had high myocardial pyruvate concentrations , above normal ratios of phosphocreatine to creatine , and near normal oxygen consumption , developed pressure , dp/dt , and cyclic adenosine monophosphate concentrations when re-equilibrated with a medium containing pyruvate or ribose as substrate , although adenosine triphosphate and adenine nucleotide concentrations were severely depressed .
