Evaluating heart failure treatment options for patients over 70 to prevent sudden cardiac death
Official title: Cardioverter DefIbriIlator PlacEMent for priMary Prevention of Sudden cArdiac Death in Patients Older Than 70 Years: A Randomized Controlled Trial
Run by Assistance Publique - Hôpitaux de Paris · NCT05373940 · Data updated 2026-11-12
This study is testing whether adding an implantable defibrillator to standard heart failure treatment can help people over 70 live longer and avoid sudden cardiac death.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients aged 70 and older with heart failure and a left ventricular ejection fraction of 35% or less.
✕Probably not a fit
Patients with advanced comorbidities or those who have recently experienced significant cardiac events may not benefit from this study.

What this trial studies
This study aims to determine if optimal heart failure therapy alone is as effective as combining it with an implantable cardioverter defibrillator (ICD) for preventing sudden cardiac death in patients aged 70 and older. It is a randomized, open-label, multicenter trial involving 730 participants over four years, with a follow-up period of 48 months. The study will compare overall survival rates between two groups: one receiving optimal therapy alone and the other receiving optimal therapy plus ICD implantation.
Why it matters
Potential benefit: If successful, this study could provide evidence to guide treatment decisions for elderly patients, potentially reducing unnecessary ICD implantations and associated complications.
How similar studies have gone: While there is limited data specifically for elderly patients, similar studies in younger populations have shown the effectiveness of ICDs, making this approach somewhat novel for the elderly demographic.

Show full inclusion / exclusion criteria
Inclusion Criteria: * ≥70 years old, * Left ventricular ejection fraction ≤ 35%, assessed by echocardiography, single-photon emission computed tomography and radionuclide ventriculography and/or cardiac magnetic resonance (CMR) (assessed at inclusion or within the 6 weeks prior to inclusion). * NYHA class II or III * Heart failure HFOT ≥ 3 months (Possible exceptions : possibility of including patients who do not tolerate the maximum dose or who do not tolerate all four therapeutic classes, as well as the possibility of not waiting for three months when one of the classes is discontinued or when dosage adjustments are made due to poor tolerance ...) * Providing informed consent * Affiliated to a French Health Insurance system. Exclusion Criteria: * Enrolled in or planning to enroll in a conflicting interventional trial (trial evaluating the interest of ICD or modifying HFOT outside the last ESC Guidelines) * Prior unstable sustained ventricular arrhythmia requiring external cardioversion * Myocardial infarction within the 40 days * Coronary artery intervention (catheter or surgical) within 90 days * History of syncope in the previous 6 months * Advanced cerebrovascular disease (cerebrovascular disease with functional repercussions or effect on the patient's autonomy) * Cognitive impairment leading to the incapacity of consent * Any disease other than cardiac disease (e.g. cancer, uremia, liver failure), associated with a likelihood of survival less than 1 year. * Patient under tutorship, curatorship, or legal safeguard * Persons deprived of their liberty by judicial or administrative decision (prisoner)
