Dynamics of left ventricular myocardial work in patients hospitalized for acute heart failure

. Left ventricular ejection fraction is the most commonly used measure describing pumping efficiency, but it is heavily dependent on loading conditions and therefore not well suited to study pathophysiologic changes. The novel concept of echocardiography-derived myocardial work (MyW) overcomes this disadvantage as it is based on left ventricular (LV) pressure-strain loops. We tracked the in-hospital changes of indices of MyW in patients admitted for acute heart failure (AHF) in relation to their recompensation status and explored the prognostic utility of MyW indices
