The ANTHEM-HFpEF 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 with preserved and mid-range ejection fraction.

Congestive Heart Failure Device: Vagus Nerve Stimulation (VNS)

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: Autonomic Neural Regulation Therapy to Enhance Myocardial Function in Heart Failure With Preserved Ejection Fraction (ANTHEM-HFpEF) Study

Estimated Enrollment: 50
Study Start Date: August 2014
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Experimental: Therapy

Right Cervical Vagus Nerve Stimulation (VNS)

Device: Vagus Nerve Stimulation (VNS)

Electrical Stimulation of the Vagus Nerve

Heart failure patients will be enrolled and implanted with a cervical VNS system on the right side. After a 2-week post-implantation recovery period and a 10-week stimulation titration period, continuous periodic stimulation will be performed for 12 months, with data collection at 3, 6, 9, and 12 months.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Patients with symptomatic heart failure, New York Heart Association (NYHA) class II/III with preserved and mid-range EF (≥40%).
