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.

A comparative study of embedded and anesthetized zebrafish in vivo on myocardiac calcium oscillation and heart muscle contraction

Frontiers in Pharmacology, 2010
The zebrafish (Danio rerio) has been used as a model for studying vertebrate development in the cardiovascular system. In order to monitor heart contraction and cytosolic calcium oscillations, fish were either embedded in methylcellulose or anesthetized

Stunned myocardium [PDF]

Vojnosanitetski Pregled, 2005
Background. Stunned myocardium is a state of delayed recovery of regional contractility after a transient period of ischemia followed by reperfusion. Case report.

Effects of Rosuvastatin and Pitavastatin on Ischemia-Induced Myocardial Stunning in Dogs

Journal of Pharmacological Sciences, 2008
Incomplete recovery of myocardial contraction after reperfusion following brief ischemia is called the “stunning phenomenon” in an animal experiment.

Vigorous Vascular Contraction Mimicking Myocardial Bridge Resulting from Digoxin Treatment in an Elderly Patient

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.

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 ...

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 ...

Myocardial contraction-relaxation coupling

American Journal of Physiology-Heart and Circulatory Physiology, 2010
Since the pioneering work of Henry Pickering Bowditch in the late 1800s to early 1900s, cardiac muscle contraction has remained an intensely studied topic for several reasons. The heart is located centrally in our body, and its pumping motion demands the attention of the observer.

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.
