Neural Cardiac Therapy for Heart Failure Study (NECTAR-HF)
Neural Cardiac Therapy for Heart Failure Study
The NECTAR-HF feasibility trial is designed to evaluate the application of right vagal nerve stimulation in heart failure patients with a New York Heart Association Class III, an ejection fraction equal to or less than 35 %, and a narrow QRS duration equal to or less than 130 ms.
The objectives of this study are to assess the impact of right vagal nerve stimulation on left ventricular remodeling, functional capacity, quality of life, and other measures in heart failure patients over a 6-month period. In addition, the study will assess the safety of the NECTAR-HF study system over an 18-month period.
Phase 2
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
  • Heart Failure
  • Congestive Heart Failure
Device: Vagal Nerve Stimulation
Patients randomized to therapy arm with receive right vagal nerve stimulation. Patients randomized to control arm will not receive right vagal nerve stimulation for the first 6-months post-implant, after which they will also receive therapy.
  • Experimental: Therapy
    Intervention: Device: Vagal Nerve Stimulation
  • No Intervention: Control
    Control group will be implanted with study system, but will receive no therapy until 6-month cross-over.
