Journal of Medicine in Scientific Research, 2022 Background Prolonged myocardial contraction and QT interval duration may be found in ischemic viable myocardium, yet it is unclear if noninvasive examination of regional nonhomogeneous myocardial mechanics and QT duration may detect patients with ...

Will the real ventricular architecture please stand up? [PDF]
, 2017 Ventricular twisting, essential for cardiac function, is attributed to the contraction of myocardial helical fibers. The exact relationship between ventricular anatomy and function remains to be determined, but one commonly used explanatory model is the ...

Cell-free cryopreserved biological agents for cardiac protection in autoimmune myocarditis: A morphofunctional animal model study [PDF]
Scripta MedicaBackground/Aim: Autoimmune myocarditis (AIM) is a condition characterised by inflammation of the heart muscle, which can lead to heart failure. The development of effective treatments is crucial for improving cardiac function and recovery.

Analytical method to measure three-dimensional strain patterns in the left ventricle from single slice displacement data [PDF]
, 2010 Background: Displacement encoded Cardiovascular MR (CMR) can provide high spatial resolution measurements of three-dimensional (3D) Lagrangian displacement. Spatial gradients of the Lagrangian displacement field are used to measure regional myocardial

A comprehensive and biophysically detailed computational model of the whole human heart electromechanics [PDF]
, 2022 While ventricular electromechanics is extensively studied, four-chamber heart models have only been addressed recently; most of these works however neglect atrial contraction. Indeed, as atria are characterized by a complex physiology influenced by the ventricular function, developing computational models able to capture the physiological atrial ...

International Journal of Gerontology, 2016 Myocardial bridge is defined as the intramyocardial course of a segment of a coronary artery. Digoxin increases the force of myocardial contraction, which augments the compression of the vessel.

Imaging the dynamics of cardiac fiber orientation in vivo using 3D Ultrasound Backscatter Tensor Imaging [PDF]
Scientific Reports, 2017, 7 (1), pp.830, 2023 The assessment of myocardial fiber disarray is of major interest for the study of the progression of myocardial disease. However, time-resolved imaging of the myocardial structure remains unavailable in clinical practice. In this study, we introduce 3D Backscatter Tensor Imaging (3D-BTI), an entirely novel ultrasound-based imaging technique that can ...

Mechanisms of exercise-induced improvements in the contractile apparatus of the mammalian myocardium [PDF]
, 2010 One of the main outcomes of aerobic endurance exercise training is the improved maximal oxygen uptake, and this is pivotal to the improved work capacity that follows the exercise training.
