Abstract
In heart failure with preserved ejection fraction, significant left ventricular diastolic abnormalities are present, despite a normal systolic ejection fraction. This article will consider whether this is consistent with the law of conservation of energy, also know as the first law of thermodynamics.
Core Tip: The term heart failure with preserved ejection fraction may be misleading, and not consistent with the first law of thermodynamics.
