Abstract

Expanding on the modern lexicon of Heart Failure (HF), the novel mechano-energetic concept of myocardial fatigue describes a transiently energy-depleted myocardium with impaired contractility and relaxation in the face of adverse haemodynamic load. It encompasses established concepts of ventricular-arterial decoupling, deranged cardiac energetics and impaired myocardial efficiency, offering an alternative explanation for functional causes of HF.
