What this trial studies

This study investigates the effects of a single low dose of whole heart external beam radiotherapy (EBRT) on patients with advanced refractory heart failure. The treatment involves administering 5 Gray of EBRT to assess its efficacy in improving left ventricular ejection fraction (LVEF) by at least 5%. The study will also evaluate safety, overall survival, hospital admissions, late toxicity, quality of life, and other heart function indicators. Participants must have stable heart failure and meet specific eligibility criteria.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with advanced refractory heart failure and a left ventricular ejection fraction of 35% or less.

Not a fit: Patients who are eligible for heart transplantation or have had previous radiotherapy involving the heart may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced heart failure who have not responded to conventional therapies.

How similar studies have performed: Preliminary data suggests potential benefits, but this approach is relatively novel and has not been extensively tested in similar studies.
