Abstract

Endovascular ultrasound renal denervation (uRDN) reduced blood pressure (BP) compared to sham at 2 months in patients with resistant hypertension in the multicenter, blinded, randomized, sham-controlled RADIANCE-HTN TRIO trial. This analysis evaluates longer-term outcomes of patients randomized to uRDN. Patients with resistant hypertension to a 3-drug combination pill were randomized to uRDN (n = 69) or sham (n = 67). From 2-5 months, patients followed a standardized anti-hypertensive medication (AHM) titration protocol. At 6 months, patients were unblinded and received AHM per standard of care. In the uRDN group, 71% (49/69) completed 36-month follow-up. Screening office BP was 159/103 on 3.9 AHM. Baseline office BP on the single-pill combination was 153/99 mmHg. At 36 months, office BP changed by -14.5 ± 26.1/-9.0 ± 14.8 mmHg from screening (p < 0.001 for both) and -8.0 ± 24.5/-5.0 ± 14.6 mmHg from baseline (p = 0.007; p = 0.022) on 3.7 AHM. The efficacy of uRDN was durable to 36 months in patients with resistant hypertension with no safety concerns.

Summary

Endovascular ultrasound renal denervation (uRDN) reduced blood pressure (BP) compared to sham at 2 months in patients with resistant hypertension in the multicenter, blinded, randomized, sham-controlled RADIANCE-HTN TRIO trial.

Why This Matters for Hirudotherapy

Adds to the evidence base on hirudin-class anticoagulants and leech-derived therapeutic agents.
