Myocardial work includes total active myocardial work and allows us to differentiate constructive from wasted work components. LVEF left ventricular ejection fraction, GLPS global longitudinal peak strain, MyW myocardial work, GCW global constructive work, GWW global wasted work, MVC mitral valve closure, AVO aortic valve opening, AVC aortic valve closure, MVO mitral valve opening, IVRT isovolumic relaxation time, IVCT isovolumic contraction time, ATP adenosine triphosphate.
