5,000-Patient registry tests kidney nerve procedure for Tough-to-Treat high blood pressure
NCT ID NCT01534299
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This registry follows 5,000 people with high blood pressure who undergo a procedure called renal denervation. The procedure uses a catheter to deliver radiofrequency energy to nerves in the kidney arteries, which may help lower blood pressure. Participants are tracked for up to 5 years to see how safe and effective the procedure is in real-world settings.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Renal denervation procedure using a catheter that delivers radiofrequency energy to nerves in the kidney arteries
- What this could lead to
- If successful, this could confirm that renal denervation is a safe and effective long-term option for lowering blood pressure in patients with uncontrolled hypertension.
- What could go wrong
- This is an observational registry, not a randomized trial, so results may be influenced by patient selection and other factors. The procedure carries risks like artery damage or bleeding, and not all patients may respond.
