Need for Speed: The Importance of Physiological Strain Rates in Determining Myocardial Stiffness

open access: yesFrontiers in Physiology, 2021
The heart is viscoelastic, meaning its compliance is inversely proportional to the speed at which it stretches. During diastolic filling, the left ventricle rapidly expands at rates where viscoelastic forces impact ventricular compliance.

Inorganic phosphate accelerates cardiac myofilament relaxation in response to lengthening

open access: yesFrontiers 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 ...
