Detaljeret beskrivelse
Interventional study
Allocation: Randomised Endpoint Classification: Safety / Efficacy Study Intervention Model: Parallel Assignment Masking: Double blind (Subject / CHF team). The interventional operator, will have no role in care of the patient following randomisation.
Primary Purpose: Treatment
Chronic Systolic Heart Failure
Device: Renal denervation (Symplicity Catheter System) Symplicity Catheter System
-Intervention: Device: Renal denervation (Symplicity Catheter System)
Patients are randomised in the cath lab to receive either renal denervation or sham procedure.
Experimental arm: Renal Denervation Control arm: No renal denervation (sham procedure)
In both arms, aftercare is provided by clinicians who are blinded to the randomised allocation arm. Subjects will have been recruited on stable heart failure therapy, and the intention is to maintain this therapy steady during followup.
