A modified Holzapfel-Ogden law for a residually stressed finite strain model of the human left ventricle in diastole [PDF]
, 2013 In this work, we introduce a modified Holzapfel-Ogden hyperelastic constitutive model for ventricular myocardium that accounts for residual stresses, and we investigate the effects of residual stresses in diastole using a magnetic resonance imaging ...

Mean and Variability of Lipid Measurements and Risk for Development of Subclinical Left Ventricular Diastolic Dysfunction [PDF]
Diabetes & Metabolism Journal, 2022 Background Subclinical left ventricular diastolic dysfunction (LVDD) is an emerging consequence of increased insulin resistance, and dyslipidemia is one of the few correctable risk factors of LVDD. This study evaluated the role of mean and visit-to-visit

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

Numerical study of hemodynamics after stent implantation during the cardiac cycle
Journal of Mechanical Engineering and Sciences, 2021 The descending aortic aneurysm is one of the most catastrophic cardiovascular emergencies resulting in high mortality worldwide. Clinical observations have pointed out that stent implantation in the sick aorta should probably allow stabilization of the ...
