Effect of changes in contractility on the index of myocardial performance in the dysfunctional left ventricle

Cardiovascular Ultrasound, 2006
Background The index of myocardial performance has prognostic power in patients with cardiomyopathy and following myocardial infarction. As the index of myocardial performance has been shown to be preload and afterload dependent, the effect of altering ...

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.

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 ...

Segmentation of Myocardial Boundaries in Tagged Cardiac MRI Using Active Contours: A Gradient-Based Approach Integrating Texture Analysis [PDF]

, 2009
The noninvasive assessment of cardiac function is of first importance for the diagnosis of cardiovascular diseases. Among all medical scanners only a few enables radiologists to evaluate the local cardiac motion. Tagged cardiac MRI is one of them.

STUDIES ON MYOCARDIAL CONTRACTION

The Keio Journal of Medicine, 1969
The relations between the right ventricular contraction and the local myo-cardial shortening measured by means of the transcatheter method were dis-cussed. The local tension-velocity-length relationships were also shown.The authors wish to express their sincere gratitude to Prof. H. Sasamoto for his generous guidance and instruction in this study.

Human cardiomyocyte calcium handling and transverse tubules in mid-stage of post-myocardial-infarction heart failure [PDF]

, 2018
Aims: Cellular processes in the heart rely mainly on studies from experimental animal models or explanted hearts from patients with terminal end-stage heart failure (HF).

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 ...

A pseudo active kinematic constraint for a biological living soft tissue: an effect of the collagen network [PDF]

, 2008
Recent studies in mammalian hearts show that left ventricular wall thickening is an important mechanism for systolic ejection and that during contraction the cardiac muscle develops significant stresses in the muscular cross-fiber direction. We suggested
