NCT01459900

Brief Summary

The purpose of this double blind, randomized and sham controlled study is to determine whether renal denervation in terms of catheter based ablation in the renal arteries is effective in lowering blood pressure in patients with treatment resistant hypertension. The blood pressure lowering effect will be evaluated by 24 hours ambulatory blood pressure measurement at baseline and after 1, 3 and 6 months of follow up. Secondary end point evaluation concerns hemodynamic measures using echocardiography, applanation tonometry and forearm plethysmography.

Outcome Measures

Primary Outcomes (1)

  • daytime systolic blood pressure assessed by 24 hours ambulatory BP measurement

    Changes in mean daytime systolic BP after 3 months is compared between groups. Also the proportion of responders versus nonresponders after 3 months is compared between groups, responders being defined as A) a minimum decrease in daytime systolic BP of 10 mmHg analysis together with and unchanged/increased number of antihypertensive drugs, or B) a decrease in daytime systolic BP of 0-10 mmHg together with a reduced number of antihypertensive drugs.

    3 months follow up

Secondary Outcomes (5)

  • ambulatory 24 hours BP measurements

    1, 3 and 6 months

  • Echocardiography

    6 months

  • Biomarkers

    1 months

  • Applanation tonometry

    6 months

  • forearm plethysmography

    6 months

Study Arms (2)

Renal artery ablation

ACTIVE COMPARATOR

By femoral access, coronary and renal angiography are performed. The patient will be sedated. In case of vessel anatomy allowing renal ablation, the patient will be randomized in the card. lab. In case of randomization to active treatment, renal artery ablation will be carried out straight away.

Procedure: Renal artery ablation

Sham

SHAM COMPARATOR

By femoral access, coronary and renal angiography are performed. The patient will be sedated. In case of vessel anatomy allowing renal ablation, the patient will be randomized in the card. lab. In case of randomization to sham procedure, no renal artery ablation are performed.

Procedure: Renal angiography

Interventions

Catheter based renal denervation by applying low power radiofrequency to the renal artery using the Ardian Medtronic Simplicity Catheter, introduced by femoral artery access.

Renal artery ablation

Renal angiography by femoral access.
