Personalized defibrillator allocation for heart failure patients

Official title: Study of Personalized Allocation of Defibrillators in Non-ischemic Heart Failure (SPANISH-1)

Run by Consorcio Centro de Investigación Biomédica en Red (CIBER) · NCT06055504 · Data updated 2026-11-12

This study is testing if a personalized method for deciding who gets a heart defibrillator can help people with heart failure just as well as the usual method.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with a diagnosis of non-ischemic dilated cardiomyopathy and an LVEF of 35% or less.

Probably not a fit

Patients with a history of coronary artery disease or other specific heart conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates a personalized approach to implantable cardioverter defibrillator (ICD) allocation for patients with non-ischemic dilated cardiomyopathy and a left ventricular ejection fraction (LVEF) of 35% or less. Participants will be randomly assigned to either a control group receiving standard ICD implantation or an intervention group where ICD implantation is guided by genetic and cardiac magnetic resonance (CMR) findings. The goal is to determine if the personalized strategy is non-inferior in preventing sudden cardiac death compared to the standard approach.

Why it matters

Potential benefit: If successful, this study could lead to more tailored and effective prevention strategies for sudden cardiac death in heart failure patients.

How similar studies have gone: While personalized approaches in cardiology are gaining traction, this specific strategy is novel and has not been extensively tested in prior studies.
