  Purpose

The purpose of this double-blind, randomized and sham controlled study is to investigate the blood pressure lowering effect of renal denervation by catheter based ablation in the renal arteries in patients with milder forms of treatment resistant hypertension. The effect on blood pressure will be evaluated by 24-hour ambulatory blood pressure measurements at baseline and after 3 and 6 months of follow up. Secondary endpoint evaluation comprises hemodynamic assessment by applanation tonometry and the cold pressor response.

Primary Outcome Measures:
  • Change from baseline in daytime systolic blood pressure (24-hour ambulatory blood pressure measurement) [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline in blood pressure (clinic and 24-hour ambulatory blood pressure measurement) [ Time Frame: 3 and 6 months ] [ Designated as safety issue: No ]
  • Change from baseline in central blood pressure, augmentation index and pulse wave velocity [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Change from baseline in cold pressor response [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Change from baseline in intensity of medical antihypertensive therapy [ Time Frame: 1, 3 and 6 months ] [ Designated as safety issue: No ]
  • Blood pressure (clinic measurement) [ Time Frame: 1, 3 and 6 months ] [ Designated as safety issue: Yes ]
  • Renal function (eGFR and electrolytes) [ Time Frame: 1, 3 and 6 months ] [ Designated as safety issue: Yes ]

Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Renal denervation by ablation of the renal arteries
By femoral access, renal angiography is performed. The patient will be sedated. In case of acceptable renal artery anatomy allowing renal ablation, the patient will be randomized in the cath. lab. If randomized to active treatment, renal artery ablation will be carried out straight away.
Procedure: Ablation of the renal arteries
Catheter-based renal denervation by applying low power radiofrequency to the renal artery using the EnligHTN Catheter, introduced by femoral artery access.
Sham Comparator: Control
By femoral access, renal angiography is performed. The patient will be sedated. In case of acceptable renal artery anatomy allowing renal ablation, the patient will be randomized in the cath. lab. If randomized to sham treatment, the procedure stops.
Procedure: Renal angiography
Renal angiography by femoral access
