The role of myocardial mechanical and QTc dispersion in detecting significant coronary artery disease

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 ...

SERCA2a ameliorates cardiomyocyte T-tubule remodeling via the calpain/JPH2 pathway to improve cardiac function in myocardial ischemia/reperfusion mice

Scientific Reports, 2021
Transverse-tubules (T-tubules) play pivotal roles in Ca2+-induced, Ca2+ release and excitation–contraction coupling in cardiomyocytes. The purpose of this study was to uncover mechanisms where sarco/endoplasmic reticulum Ca2+ ATPase (SERCA2a) improved ...

Intravenous Transplantation of an Ischemic-specific Peptide-TPP-mitochondrial Compound Alleviates Myocardial Ischemic Reperfusion Injury

ACS Nano, 2023
It is known that mitochondrial dysfunction is a critical factor involved in myocardial ischemia–reperfusion injury. Mitochondrial transplantation has been suggested as an effective therapeutic strategy to protect against myocardial ischemia–reperfusion ...

Lipofundin® MCT/LCT 20% increase left ventricular systolic pressure in an rat heart model via increase of intracellular calcium level [PDF]

Korean Journal of Anesthesiology, 2016
BackgroundLipid emulsions have been used to treat various drug toxicities and for total parenteral nutrition therapy. Their usefulness has also been confirmed in patients with local anesthetic-induced cardiac toxicity.

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
