Abstract

In order to investigate the energetic status of the aged heart during ischemia and reperfusion we perfused female Wistar rats 6, 12 and 24 month old. The hearts were subjected to 15 min of global total ischemia plus 30 min of reperfusion. NMR spectra were collected during the entire experimental period to have the in vivo monitoring of the changes in intracellular pH and intracellular ATP, PCr and Pi contents. In the first 8 min of ischemia the fall of pH was similar in the 3 groups of rats, while at the end of the ischemic period the young rat hearts showed an intracellular pH significantly lower than aged rat hearts. At the end of reperfusion, ATP and PCr contents appeared significantly higher in the adult and aged hearts as compared to the young. The Pi content, on the contrary, was significantly lower in aged than young rat hearts. We suggest that the hearts of adult and aged animals, at the end of reperfusion, showed larger energetic recovery, in our experimental conditions of brief ischemia, than young hearts.
