Renal Sympathetic Denervation From the Adventitia on Resistant Hypertension（RSDARH）

March 11, 2020 updated by: Henan Institute of Cardiovascular Epidemiology

Efficacy and Safety of Renal Sympathetic Denervation From the Adventitia on Resistant Hypertension.

As one of the most common chronic diseases,The adult prevalence of hypertension is approximately 26.4% at present and will rise to 29.2% by 2025.Renal sympathetic denervation from the intima of renal artery has emerged as a potential treatment for resistant hypertension. However, renal sympathetic nerve are mainly located in the adventitia,and there is no report on renal sympathetic denervation from the adventitia of renal artery.This study is a multicenter,randomized,single-blind study,and aimed to observe the safety and efficacy of radiofrequency ablation of the renal artery from the adventitia on the basis of laparoscopic techniques for patients with resistant hypertension.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
