Primary Outcome Measures:
  • Left ventricular end-systolic dimension (LVESD) [ Time Frame: 6-months post-implant ] [ Designated as safety issue: No ]
    Echocardiography LVESD

  • All-cause mortality [ Time Frame: 18-months post-implant ] [ Designated as safety issue: Yes ]
    All-cause mortality

Secondary Outcome Measures:
  • Left ventricular remodeling [ Time Frame: 6-months post-implant ] [ Designated as safety issue: No ]
    Echocardiography parameters of left ventricular structure and function (e.g., LVEF, LVESV and LVEDV, LVEDD)

  • Functional capacity [ Time Frame: 6-months post-implant ] [ Designated as safety issue: No ]
    Assessment of functional capacity (e.g., peak VO2, anaerobic threshold)

  • Quality of Life [ Time Frame: 6-months post-implant ] [ Designated as safety issue: No ]
    Assessments of patient reported quality of life (i.e., MLWHFQ and SF-36)

  • Heart failure status [ Time Frame: 6-months post-implant ] [ Designated as safety issue: No ]
    Assessment of heart failure status (i.e., NYHA Class)

Estimated Enrollment: 250
Study Start Date: June 2011
Estimated Study Completion Date: January 2018
Estimated Primary Completion Date: May 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Therapy 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.
No Intervention: Control
Control group will be implanted with study system, but will receive no therapy until 6-month cross-over.

Detailed Description:

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.
