A, Influence of age on preischemic and postischemic responses to 5-HT and to l-NMMA. Each bar represents the mean of six hearts ± SEM. Between each age group, p < 0.05, and p < 0.05 between preischemic (hatched bars) and postischemic (black bars) values in each age group. B, Influence of age on postischemic recovery of coronary response to 5-HT (hatched bars) and to l-NMMA (black bars). Each bar represents the mean of six hearts ± SEM. Between each age group, p < 0.05, except between groups 1 and 4 (p < 0.02). CF, Coronary flow.

A. Effect of age on preischemic and postischemic coronary responses to GTN. Each bar represents the mean of six hearts ± SEM. Between each age group, p was not significant, and p was also not significant between preischemic (hatched bar) and postischemic (black bar) values in each age group. B, Effect of age on postischemic recovery of coronary response to GTN. Between each age group, p was not significant. CF, Coronary flow.
