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.
摘要
在射血分数保留的心力衰竭中，尽管收缩期射血分数正常，但仍存在显著的左心室舒张功能异常。本文将探讨这是否符合能量守恒定律，即热力学第一定律。
