Perirenal Adipose Tissue Modification Therapy for Resistant Hypertension
China220 participantsStarted 2025-11-20
Plain-language summary
The goal of this clinical trial is to investigate if focused power ultrasound (FPU) targeted perirenal adipose tissue modification therapy would be effective and safe in treating resistant hypertension. The primary outcome of the study is the difference in the reduction of 24h mean systolic blood pressure between treatment and sham procedure groups 6 months after treatment. The secondary outcomes include the reduction of clinic blood pressure 1, 3, and 6 months after treatment, the reduction of 24h mean blood pressure 1, 3, and 6 months after treatment, and the drug burden of antihypertensive treatment. The safety evaluation includes the incidence of all-cause death, cardiovascular events (stroke and myocardial infarction), renal failure, and other adverse events.
