About this study

Heart failure (HF) continues to be a leading cause of morbidity and mortality worldwide, despite advances in treatment. HF is often characterized by an altered metabolism in the heart, where glucose is favored over fatty acids as the primary energy substrate. This metabolic shift has been hypothesized to contribute to disease progression. Previous studies using animal models have demonstrated that restoring fatty acid metabolism through dietary intervention can reverse the adverse metabolic effects and improve heart function. A transgenic murine model with mitochondrial defects, for instance, exhibited improved cardiac function after an HFD intervention. These findings were reinforced by a translational pig model of non-ischemic DCM, where a high-fat diet significantly improved LVEF compared to a standard diet. Building upon these promising preclinical results, a small-scale human study showed that lipid infusion, rather than glucose, improved cardiac function in HF patients. However, the long-term benefits of a HFD in heart failure patients have yet to be thoroughly explored. The HF4HF trial aims to fill this gap by evaluating the effects of an HFD over a two-month period in patients with non-ischemic DCM and reduced LVEF. The "High Fat Diet for Heart Failure" (HF4HF) study is a proof-of-concept randomized controlled trial designed to investigate the efficacy of a high-fat diet (HFD) as a therapeutic intervention in patients with non-ischemic dilated cardiomyopathy (DCM) a…
