Therefore, inhibition of this enzyme, prevent link reaction, and there reduction in pyruvate utilization and therefore prevent the  commencements of Citric acid cycle, with consequent  reduction in glucose oxidation. as there is no  reaction of acetyl Co A (from link reaction from pyruvate )   with 4C oxaloacatate in the kreb Cycle to form Citrate in Kreb's cycle. Thus the heart  depends on fatty acid supply for energy.
