Clinical Trial Summary

This randomized, blinded, sham-control trial aims to evaluate the efficacy and safety of a novel focused power ultrasound mediated inferior perirenal adipose tissue modification therapy for essential hypertension.

Description:

The increase of visceral fat is closely related to the occurrence of hypertension, and it is one of the main independent risk factors of hypertension. Visceral fat has been recognized as an important endocrine organ, and a variety of factors secreted by visceral fat lead to an increased risk of cardiovascular disease. Peri-renal fat is a special type of visceral fat which is different from other type of visceral fat in histology, physiology, and functions. The positon of peri-renal fat is more stable than other visceral fat, which might be influenced by breath or body position changes.Studies have found that perirenal fat is an early predictor of ASCVD, and its accumulation is closely related to the occurrence and development of ASCVD. Therefore, the reduction or modification of visceral fat,especially peri-renal fat , has a sufficient scientific basis for the treatment of hypertension.

In our previous experiments, this novel focused power ultrasound can rapidly and efficiently promote the perirenal adipose tissue fibrosis and control the blood pressure in the model of swine. Moreover, the investigators performed a single arm, small sample study to investigate the feasibility of the novel focused power ultrasound to modify the inferior perirenal adipose tissue in human volunteers, showing that this kind of method was feasible and safe.

In this study, the investigators aim to further evaluate the efficacy and safety of a novel focused power ultrasound mediated inferior perirenal adipose tissue modification therapy for essential hypertension.

Intervention

Device:
• focused power ultrasound mediate inferior perirenal adipose tissue modification
This novel focused power ultrasound is an externally delivered, completely noninvasive focused therapeutic ultrasound device. It is capable of focusing the resulting ultrasound beam to a small "cigar"-shaped volume and monitoring the temperature of the target area, which leads to the rapid elevation of the peri-renal adipose tissue temperature and the destruction of target tissue eventually.
• sham-control group
participants will receive the sham control therapy(including peri-renal fat ultrasonic measurement and localization,focused ultrasound treatment parameters setting),however,without initiating the focused ultrasound equipment.
