Sound waves target kidney fat to lower stubborn blood pressure
NCT ID NCT07232966
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether focused power ultrasound can safely lower blood pressure in people with resistant hypertension (high blood pressure that doesn't respond to three or more drugs). About 220 adults will receive either the ultrasound treatment or a sham procedure. The main goal is to see if the treatment reduces average 24-hour systolic blood pressure after 6 months, while also monitoring for side effects like heart attack or kidney problems.
