Barostim-aktiveret Neurohormonel Intervention til Forbedring af Behandling af Hjertesvigt (BENEFIT-HF)

6. november 2026 opdateret af: CVRx, Inc.

Barostim-understøttet Neurohormonel Intervention til Forbedring af Behandling af Hjertesvigt (BENEFIT-HF)

The purpose of BENEFIT-HF is to demonstrate the safety and effectiveness of Baroreflex Activation Therapy (BAT) with the Barostim System in participants with heart failure, defined as NYHA Functional Class II or III, LVEF < 50% and NT-proBNP < 5,000 pg/mL despite being treated with Guideline-Directed Medical Therapies (medications and devices). It includes demonstration that treatment with the Barostim System, relative to usual care medical management, reduces the rate of all-cause mortality and Heart Failure Morbidity (Cardiac Transplant, Durable LVAD, or Worsening Heart Failure Events).

    • Unstable angina
    • Percutaneous coronary intervention (e.g. PTCA)
    • Cerebral vascular accident or transient ischemic attack
    • Cardiac arrest
    • Surgical cardiac intervention (e.g., CABG, cardiac ablation, valve replacement, CRT/ICD implantation, IPG battery replacements)
  9. Surgery planned to occur within 45 days of the Barostim implant procedure. This includes pacemaker or ICD implants or battery replacements.

  10. Enrolled and active in another clinical trial (e.g. device, pharmaceutical, or biological) unless approved by the CVRx Clinical Research department.

  11. Unable or unwilling to fulfill the Protocol medication compliance and follow-up requirements, for reasons including but not limited to an unresolved history of alcohol or substance abuse or psychiatric disorder. Participant is a member of a vulnerable population who, in the judgment of the investigator, is unable to give Informed Consent for reasons of incapacity, immaturity, adverse personal circumstances or lack of autonomy. This may include individuals with mental disability, persons in nursing homes, impoverished persons, persons in emergency situations, homeless persons, nomads, refugees, and those permanently incapable of giving informed consent.
