Acetate suppresses myocardial contraction via the short-chain fatty acid receptor GPR43 [PDF]
Frontiers in Physiology, 2022 The heart has high energy requirements, with an estimated 40%–60% of myocardial ATP production derived from the oxidation of fatty acids under physiological conditions.

Speckle tracking echocardiography analyses of myocardial contraction efficiency predict response for cardiac resynchronization therapy [PDF]
Cardiovascular Ultrasound, 2018 Background In patients with left ventricular (LV) dysssynchrony, contraction that doesn’t fall into ejection period (LVEj) results in a waste of energy due to inappropriate contraction timing, which was now widely treated by cardiac resynchronization ...

Myocardial Contraction during the Diastolic Isovolumetric Period: Analysis of Longitudinal Strain by Means of Speckle Tracking Echocardiography [PDF]
Journal of Cardiovascular Development and Disease, 2018 Background: According to the ventricular myocardial band model, the diastolic isovolumetric period is a contraction phenomenon. Our objective was to employ speckle-tracking echocardiography (STE) to analyze myocardial deformation of the left ventricle ...

Regulation of myocardial contraction as revealed by intracellular Ca2+ measurements using aequorin [PDF]
Journal of Physiological SciencesOf the ions involved in myocardial function, Ca2+ is the most important. Ca2+ is crucial to the process that allows myocardium to repeatedly contract and relax in a well-organized fashion; it is the process called excitation–contraction coupling.

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.

Myocardial contraction fraction predicts mortality in the oldest old [PDF]
International Journal of Cardiology: Heart & Vasculature, 2022 Background: People over the age of 85 are the world's most rapidly growing age group. Ejection fraction (EF) may be limited prognostically in this population and myocardial contraction fraction (MCF) may be more accurate.

Conceptualizing myocardial contractility as an emergent property that characterizes myocardial contraction [PDF]
Frontiers in PhysiologyMyocardial contractility (MC) is a fundamental concept that is widely used to describe the cardiac muscles’ mechanical function, yet its definitions in textbooks and literature are vague, inconsistent, and often contradictory.

A simple phenomenological approach for myocardial contraction: formulation, parameter sensitivity study and applications in organ level simulations [PDF]
Mechanics of Soft Materials, 2021 Contraction in myocardial tissue is the result of a complex process through which chemical energy on the cellular level is converted into the mechanical energy needed to circulate blood throughout the body.
