Structure-based finite strain modelling of the human left ventricle in diastole [PDF]

International Journal for Numerical Methods in Biomedical Engineering, 2013
Finite strain analyses of the left ventricle provide important information on heart function and have the potential to provide insights into the biomechanics of myocardial contractility in health and disease. Systolic dysfunction is the most common cause

Titin Determines the Frank-Starling Relation in Early Diastole

Journal of General Physiology, 2003
Titin, a giant protein spanning half the sarcomere, is responsible for passive and restoring forces in cardiac myofilaments during sarcomere elongation and compression, respectively.

Evaluation of the intraventricular hemodynamics of patients with left ventricular dysfunction via vector flow mapping [PDF]

Frontiers in Cardiovascular Medicine
BackgroundVorticity, measured via new vector flow mapping (VFM), a quantitative marker of vortex dynamics, can reflect hemodynamic changes more sensitively, potentially offering complementary information to conventional echocardiographic indices of ...

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

Delineation and Analysis of Seismocardiographic Systole and Diastole Profiles [PDF]

IEEE Transactions on Instrumentation and Measurement, 2020
Precise estimation of fiducial points of a seismocardiogram (SCG) signal is a challenging problem for its clinical usage. Delineation techniques proposed in the existing literature do not estimate all the clinically significant points of an SCG signal ...

Modelling of fibre dispersion and its effects on cardiac mechanics from diastole to systole

Journal of Engineering Mathematics, 2021
Detailed fibre architecture plays a crucial role in myocardial mechanics both passively and actively. Strong interest has been attracted over decades in mathematical modelling of fibrous tissue (arterial wall, myocardium, etc.) by taking into account ...

Diastolic and Systolic Longitudinal Myocardial Velocities of Healthy Racing Pigeons (Columba livia f. domestica) Measured by Tissue Doppler Imaging

Veterinary Sciences, 2021
Tissue Doppler imaging (TDI) is a noninvasive sonographic method of acquiring and quantifying myocardial velocities. This technique is used in human and small animal medicine to diagnose cardiac diseases.

The impact of cardiac loading on a novel metric of left ventricular diastolic function in healthy middle‐aged adults: Systolic–diastolic coupling

Physiological Reports, 2021
Aims Left ventricular (LV) restoring forces are primed by ventricular deformation during systole and contribute to cardiac relaxation and early diastolic suction.
