Fructose-1,6-diphosphate (FDP), hemodynamics and heart metabolism: preliminary experimental studies.

Fructose-1,6-diphosphate (FDP) has been reported to exert beneficial effects on several cardiac functions. We studied the effects of FDP on the biochemical and dynamic functions of the heart in anesthetized dogs. Significant effects of FDP were noted mostly as related to pyruvate and lactate metabolism. The results seem to indicate that FDP may improve heart metabolism, and coronary function in restricted animals.
