Abstract
The relevance of radical formation in disturbances of energy metabolism in the postischemic heart is not clear. This study provides the first evidence of a significant correlation between the amount of oxy-radicals trapped in the effluent of isolated hearts upon reperfusion and the decreased myocardial content of phosphocreatine and ATP. This suggests that the loss of high-energy compounds might contribute to oxy-radical production during reperfusion. The application of ESR spin trapping and of NMR technique to the same heart is a new approach to investigate the pathobiochemical relevance of free radicals for the heart muscle.Keywords
