Brief Summary:
The ANTHEM-HF Study is designed to demonstrate the safety and efficacy of vagus nerve stimulation (VNS) with the Cyberonics VNS Therapy System for the treatment of subjects with symptomatic heart failure.

Condition or disease Intervention/treatment Phase
Congestive Heart Failure Device: Vagus Nerve Stimulation (VNS) Phase 1 Phase 2

Detailed Description:
Heart failure patients will be enrolled and randomized to cervical VNS implantation on either the left side or right side. After a 2-week post-implantation recovery period and a 10-week stimulation titration period, continuous periodic stimulation will be performed for 6 months, with data collection at 3 months and 6 months.
