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 ...

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.

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.
