Overview

To compare the antihypertensive effect of renal denervation with the Paradise™ system with that of a sham procedure in hypertensive patients receiving two antihypertensive drugs at the time of consent, and treated with a duo combination antihypertensive pill.

Eligibility

Inclusion Criteria :

• Patients who have received antihypertensive treatment with two antihypertensive drugs (ARB/ACE inhibitor and Ca channel antagonist, either as a single agent or as a combination) for at least 4 weeks prior to obtaining consent, with no change in the type or dosage.
• Patients with a mean seated office blood pressure of between 140 mmHg and 180 mmHg systolic and between 90 mmHg and 110 mmHg diastolic at screening visit.
• Patients with a mean 24-hour ABPM (ambulatory blood pressure measurement) of between 130 mmHg and 170 mmHg systolic and between 80 mmHg and 105 mmHg diastolic at baseline visit

Exclusion Criteria

• Lacks appropriate renal artery anatomy for renal denervation
• Secondary hypertension other than sleep apnea
• Type 1 diabetes mellitus or uncontrolled Type 2 diabetes
• Any history of cerebrovascular event or severe cardiovascular event, within 6 months prior to consent
• Repeated hospitalization for hypertensive crisis (twice or more) within 12 months prior to obtaining consent, or any hospitalization for hypertensive crisis within 3 months prior to obtaining consent
• Patients prescribed to drugs that have antihypertensive effects for other chronic diseases, and the investigator considers that discontinuation of these drugs may pose a serious risk to health
• Patients who are taking drugs known to affect blood pressure and the investigator judges that it is not possible to discontinue these drugs during the study period
