Lactate:pyruvate ratios in young and old Fisher 344 rat hearts

Group n Lactate/Pyruvate ratio
Young 12 16.8 ± 2.2
Young-ARI 9 6.8 ± 2.8#
Old 6 36.2 ± 8.8*
Old-ARI 5 7.2 ± 3.1#
Old-SDI 5 8.9 ± 4.4#

p<0.05 Old-ARI, Old-SDI vs Old, young-ARI vs Young. The lactate/pyruvate ratios were measured after perfusion for one hour under normoxic conditions.
