Representative 22-week spectra of [2-13C]pyruvate metabolism in a sham and infarcted animal: in vivo 13C label incorporation into citrate, glutamate, and acetylcarnitine is decreased in the infarcted heart when compared with sham heart. This image is enlarged from the complete spectrum to highlight the glutamate, citrate, and acetylcarnitine peaks. Pyruvate hydrate, the nonmetabolic product of pyruvate, is used to provide scale.
