Renal nerve stimulation for patients with uncontrolled hypertension undergoing renal denervation

National Tawan University Hospital

PHASE4 · National Taiwan University Hospital · NCT05421767

This study is testing if adding renal nerve stimulation can help lower blood pressure in people with hard-to-control hypertension who are also getting renal denervation.

What this trial studies

This study investigates the effects of renal nerve stimulation (RNS) on blood pressure changes in patients with uncontrolled hypertension who are undergoing renal denervation (RDN). It aims to determine if a specific cutoff value of RNS-induced systolic blood pressure change can serve as a useful clinical endpoint for RDN therapy. The study will assess the hypothesis that intense RDN can enhance the effectiveness of the procedure. By evaluating the relationship between RNS and blood pressure response, the research seeks to improve treatment outcomes for resistant hypertension.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 20-80 with uncontrolled hypertension and a glomerular filtration rate above 45 mL/min.

Not a fit: Patients with unsuitable renal artery anatomy or untreated secondary hypertension may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to better management of resistant hypertension, improving patient outcomes and quality of life.

How similar studies have performed: Previous studies have shown promising results with renal denervation techniques, indicating potential success for this novel approach.
