Advanced or End-stage Heart Failure

The RADIATE-HF study is a prospective, interventional, single-center, open-label, non-randomized study conducted at the Rennes University Hospital. The goal of this proof-of-concept trial is to demonstrate that low-dose cardiac radiation therapy (5 Gy) improves left ventricular function by more than 5% in the medium term in patients with advanced or end-stage heart failure. The primary endpoint is the difference between the baseline value and the 6-month value of the FEVG as assessed by cardiac MRI. The study includes a single group of 20 patients receiving the intervention (cardiac radiation). The study is being conducted at a single investigator site.
