Abstract
Despite significant advancements in the past decades in the understanding of and targeted treatments for heart failure (HF), it remains a deadly disease with a high risk of hospitalizations and reduced cardiorespiratory fitness, ultimately leading to reduced quality of life (QoL). Notably, patients admitted to the hospital for acute decompensated HF present with minimal therapeutic options. Lifestyle interventions, such as diet, have shown promising data in improving HF-related outcomes; however, very little is known about their role in decompensated patients admitted for acute HF.
