Overview
Brief Summary
The aim of this study is to assess whether renal denervation (RD) added to usual care compared to usual care alone reduces blood pressure (BP) as determined with ambulatory BP monitoring (ABPM) after 6 months in subjects with an average day-time systolic BP of at least 135 mmHg as determined with use of ABPM, despite use of three or more BP lowering agents or with documented intolerance or contraindication for to 2 or more of the 4 major classes of antihypertensive drugs (ACEi/ARB, calcium channel blockers, betablockers and diuretics) obstructing use of 3 antihypertensives
Further aims are to assess the effect of renal denervation on the use of BP lowering agents, to explore the effect of renal denervation in strata of estimated glomerular filtration rate (eGFR) (eGFR 20-60 mL/min per 1.73m2 and eGFR>60 mL/min per 1.73m2) and according to baseline office BP.
Randomization will be stratified by hospital and eGFR and will be at a 2:1 ratio.

Eligibility Criteria
Inclusion Criteria
- •Individual has a mean day-time SBP ≥ 135 mmHg, as determined with the use of ABPM, while using 3 or more antihypertensive agents for at least 3 months prior to inclusion or with documented intolerance to 2 or more of the 4 major classes antihypertensive drugs ( ACE/ARB, Calcium channel blocker, Beta Blocker, Diuretic) and no possibility to take 3 anti-hypertensive drugs.
- •Individual is ≥18 years of age.
Exclusion Criteria
