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

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 ...

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

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 ...

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.

A comprehensive and biophysically detailed computational model of the whole human heart electromechanics [PDF]
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 ...

Imaging the dynamics of cardiac fiber orientation in vivo using 3D Ultrasound Backscatter Tensor Imaging [PDF]
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 ...

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 ...
