A special "anoxia test" was developed with isolated guinea pig atria to test influences on the anoxic energy balance. Adenine, ribose, nicotinic acid or nicotinamide added as precursors to nutrition solutions inhibit the loss of cardiac adenine and pyridine nucleotides during anoxia and improve the energy balance under aerobic and anaerobic conditions in the myocardium.
