Zapping kidney nerves may tame both hypertension and anxiety
NCT ID NCT05438446
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This trial tests whether a procedure called renal denervation — which uses ultrasound to calm overactive nerves around the kidneys — can lower blood pressure and reduce anxiety in people with uncontrolled hypertension. Sixty adults aged 30 to 70 with high blood pressure and elevated anxiety scores will be randomly assigned to receive the procedure or standard care. Researchers will track changes in blood pressure, anxiety, stress, and quality of life over six months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a catheter-based procedure that uses ultrasound energy to ablate nerves around the kidney arteries
- What this could lead to
- If it works, this could offer a new way to treat both high blood pressure and anxiety without daily medication.
- What could go wrong
- This is a small, early-phase trial with only 60 participants. The procedure involves risks like artery damage, and it is unclear if the anxiety benefit will be lasting or meaningful.

Inclusion Criteria: * Consecutive patients aged 30-70 years with arterial hypertension diagnosed at least 3 months prior to the inclusion. * Office blood pressure (OBP) \>140/90mmHg and \<160/100 mmHg * Either no baseline hypertension treatment or hypertension treatment with one drug. The antihypertensive treatment will include a renin-angiotensin system (RAS) blocker \[either an angiotensin-converting enzyme inhibitor (ACEI) or an angiotensin receptor blocker (ARB)\] or a calcium channel blocker (CCB). * Unchanged antihypertensive therapy during the prior 8 weeks. * Patients with baseline anxiety subscore ≥ 8 according to the Hospital Anxiety and Depression Scale (HADS) Exclusion Criteria: * Patients with secondary arterial hypertension or under treatment with b-blockers, diuretics, mineralocorticoid receptors antagonists (MRAs) or a centrally acting alpha-adrenergic agonist. * Patients under treatment with antidepressants and/or anxiolytic drugs. * Patients with a glomerular filtration rate (eGFR)\] \<45 ml / min / 1.73 m2 calculated using the CKD-EPI formula15. * Patients with evidence of any of the following criteria on either renal artery side: * Main renal artery diameter \< 3.0 mm or \> 8 mm * Main renal treatable artery length \< 20 mm * Presence of renal artery stenosis of any origin ≥ 30% * Accessory arteries with diameter ≥ 2mm \<3.0 mm * Calcification in renal arteries at location where energy is to be delivered * A single functioning kidney * Prior renal denervation procedure * Presence of abnormal kidney tumors * Renal artery with aneurysm * Pre-existing renal stent or history of renal artery angioplasty * Pre-existing aortic stent or history of aortic aneurysm * Fibromuscular disease of the renal arteries * Iliac/femoral artery stenosis precluding insertion of the Paradise Catheter * Patients with a history of acute coronary syndrome or stroke during the previous six months or Scheduled coronary interventional therapy during the next six months. * Patients with permanent atrial fibrillation, chronic heart failure and NYHA functional status II-IV, Cancer under therapy (radiotherapy, chemotherapy, immunotherapy) * Patients with life expectancy \<1 year (at the time of inclusion). * Pregnant women or women who are planning to become pregnant. * Patients who do not provide written consent to participate in the study
