Clinical trials

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) and reduced left ventricular ejection fraction (LVEF). The study hypothesizes that cardiac metabolic reprogramming, achieved through a controlled nutritional intervention involving an HFD, can enhance systolic function, myocardial energetics, and overall heart function in heart failure (HF) patients. Cofunded by the European Commission and national entities, the trial is spearheaded by a consortium of cardiovascular research centers across four countries: Spain, Italy, France, and Romania.

Prospective, randomized, multicenter, open-label clinical trial to evaluate the safety and efficacy of a 3-week ibuprofen tapering regimen compared to conventional analgesic treatment (acetaminophen) in patients with acute myocarditis and left ventricular ejection fraction ≥50%. The objective is to assess the reduction in late gadolinium enhancement on cardiac magnetic resonance imaging at 6-month follow-up.

Multinational, prospective, proof of concept phase II, double-blinded, sham-controlled, randomized clinical trial (RCT) to evaluate the efficacy and safety of Remote Ischaemic PreConditioning (RIPC) in Lymphoma patients receiving anthracyclines.
