Inorganic phosphate accelerates cardiac myofilament relaxation in response to lengthening

Frontiers in Physiology, 2022
Myocardial relaxation in late systole is enhanced by increasing velocities of lengthening. Given that inorganic phosphate (Pi) can rebind to the force-producing myosin enzyme prior to MgADP release and hasten crossbridge detachment, we hypothesized that ...
