Myocardial Acceleration During Isovolumic Contraction [PDF]

Circulation, 2005
Background— Acceleration of the mitral ring during isovolumic contraction has been proposed as a load-independent index of global left ventricular (LV) contractility. This study investigates whether myocardial isovolumic acceleration (IVA) reflects regional contractility.

Transmural Myocardial Mechanics During Isovolumic Contraction

JACC: Cardiovascular Imaging, 2009
We sought to resolve the 3-dimensional transmural heterogeneity in myocardial mechanics observed during the isovolumic contraction (IC) phase.Although myocardial deformation during IC is expected to be little, recent tissue Doppler imaging studies suggest dynamic myocardial motions during this phase with biphasic longitudinal tissue velocities in left ...

Speckle-tracking echocardiography combined with imaging mass spectrometry assesses region-dependent alterations [PDF]

, 2020
Left ventricular (LV) contraction is characterized by shortening and thickening of longitudinal and circumferential fibres. To date, it is poorly understood how LV deformation is altered in the pathogenesis of streptozotocin (STZ)-induced type 1 diabetes

The impact of myocardial compressibility on organ-level simulations of the normal and infarcted heart

Scientific Reports, 2021
Myocardial infarction (MI) rapidly impairs cardiac contractile function and instigates maladaptive remodeling leading to heart failure. Patient-specific models are a maturing technology for developing and determining therapeutic modalities for MI that ...

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.

Cell-free cryopreserved biological agents for cardiac protection in autoimmune myocarditis: A morphofunctional animal model study [PDF]

Scripta Medica
Background/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.
