Figure 3 Values for myocardial fatty acid utilization (MFAU) and oxidation (MFAO) and myocardial glucose utilization (MGU) all corrected for myocardial oxygen consumption (MVO₂). Both MFAU/MVO₂ and MFAO/MVO₂ were lower in the older subjects compared with younger subjects. The MGU/MVO₂ did not differ between the groups. FFA = free fatty acids. *p < 0.005; **p < 0.004. Open bar = younger subjects; solid bar = older subjects.
