Primary Outcome Measures:
  • Evaluate the Reduction in Left-ventricular End Systolic Volume Index (LVESVi) After 6 Months of Spinal Cord Stimulation (SCS) Therapy in the Treatment Arm Compared to the Control Arm. [ Time Frame: Baseline and 6 months ]

Secondary Outcome Measures:
  • Characterize the Change in proBNP Between the Treatment Arm and Control Arm Through 6 Months [ Time Frame: Baseline and 6 Months ]
  • Characterize the Change in Peak Oxygen Uptake Between the Treatment Arm and Control Arm Through 6 Months [ Time Frame: Baseline and 6 Months ]

Enrollment: 81
