Determining the Feasibility of Spinal Cord Neuromodulation for the Treatment of Chronic Heart Failure (Defeat-HF)

Lee Goldberg, MD


Why is this study being done?
The purpose of this study is to determine the feasibility of spinal cord stimulation (SCS) as a chronic therapy for systolic heart failure.

Who is eligible to participate in this study?
  • Left Ventricular Ejection Fraction (LVEF) of 35 percent or less
  • New York Heart Association (NYHA) functional Class III at time of screening
  • QRS duration less than 120 milliseconds (ms)
  • Left Ventricular End Diastolic Diameter (LVEDD) of 55 millimeters (mm) to 80 mm as determined by echocardiography within the past 6 months
  • Receiving stable optimal medical therapy for heart failure prior to enrollment
  • Serum creatinine less than or equal to 3.0 milligrams per deciliter (mg/dL)
  • 18 years of age or older
  • Willing and able to comply with study procedures
  • Expected lifespan greater than 12 months beyond study enrollment as assessed by physician
  • Interruption of thromboprophylaxis (e.g., heparin, LMWH, warfarin, aspirin, dabigatran, clopidogrel) would pose an unacceptable health risk (e.g., patient with an abnormal bleeding time), as determined by physician
  • Polyneuropathy
  • Requires diathermy including shortwave diathermy, microwave diathermy, or therapeutic ultrasound diathermy

  • Has chemotherapy-induced heart failure
  • Has reversible cardiomyopathy
  • Has severe mitral regurgitation (greater than 60 percent regurgitant fraction or greater than 0.3 centimeters squared (cm2) regurgitant orifice area)
  • Has diagnosed unstable angina pectoris
  • Has unstable coronary artery disease
  • Has a Cardiac Resynchronization Therapy (CRT) device implanted and is receiving CRT therapy
  • Has a non-Medtronic Implantable Cardioverter Defibrillator (ICD), pacemaker, or any non-transvenous defibrillation lead
