Cardiac lactate release as estimated subtracting [3-¹³C]-L-lactate cardiac uptake to the natural substrate net balance in 5 N-AGT (gray line), 4 DCM-NGT (dotted black line), and 4 DCM-AGT (continuous black line) in the 3 phases of the study protocol: Rest, Pacing, and Recovery. The plotted values are mean ± SEM. The thin gray lines represent the SEM of the N-AGT group.
