The Positive Inotropic Effect of Pyruvate Involves an Increase in Myofilament Calcium Sensitivity

Pyruvate is a metabolic fuel that is a potent inotropic agent. Despite its unique inotropic and antioxidant properties, the molecular mechanism of its inotropic mechanism is still largely unknown. To examine the inotropic effect of pyruvate in parallel with intracellular calcium handling under near physiological conditions, we measured pH, myofilament… CONTINUE READING
