THE INHIBITORY EFFECT OF ACETOACETATE ON MYOCARDIAL CONTRACTION
The Lancet, 1962Williamson and Krebs 1 and Hall 2 have recently reported that acetoacetate, when added to the perfusion medium of an isolated heart in concentrations as high as or higher than in cases of mild ketosis, is oxidised in preference to glucose. These workers, and also Ottaway and Sarkar,3 have shown that lactate accumulated in the perfusion fluid ...

Pathological contraction bands affecting myocardial cells are observed in many different human conditions and in different experimental models. Their morphology was defined long ago but we need to understand the pathogenesis and functional meaning. A distinction between different histological forms of contraction bands and their quantification in a ...

Tonic component of myocardial contraction
Cell Calcium, 2004Calcium transients and contractions of cardiac myocytes consist of phasic component, relaxing spontaneously independently of membrane voltage and of the tonic component (TC) relaxing only upon repolarization. Experimental data reviewed in this article suggest that most Ca(2+) activating TC is released from sarcoplasmic reticulum (SR) via the ryanodine ...

Myocardial Contraction and Long QT Syndrome
Trends in Cardiovascular Medicine, 2011The long QT syndrome is an inherited cardiac arrhythmic disease that has been regarded as a purely electrical disease. However, sporadic reports have indicated that myocardial contraction abnormalities are present in these patients. Novel echocardiographic techniques such as strain echocardiography have made it possible to further elucidate cardiac ...

Modeling Ischemia-Induced Dyssynchronous Myocardial Contraction
Anesthesia & Analgesia, 2006Left ventricular (LV) contraction dyssynchrony is not easily quantified. We previously described a model for quantifying LV dyssynchrony that referenced regional amplitude and phase angles to global LV systole using esmolol-induced regional dyskinesis.

Endothelial Modulation of Myocardial Contraction
Endothelium, 1994Both endocardial endothelium and coronary vascular endothelium in the heart influence myocardial contraction by releasing diffusible agents that affect the subjacent myocardium. This effect of cardiac endothelium can be demonstrated both in isolated tissue preparations as well as pump function in intact hearts both in vitro and in vivo. Agents released
