FlashPoint Renal Denervation Under Columbus 3D Mapping System Guidance for Treating Hypertension

This trial is a prospective, multi-center, randomized controlled clinical study to verify the safety and efficacy of the renal artery radiofrequency ablation system under the guidance of the three-dimensional cardiac electrophysiological mapping system in the application of renal denervation of essential hypertension，designed to include drug-control research and sham-control resarch. Provide the basis for product registration and marketing and clinical application. Drug-control research include 65 subiects (5 are subjects trained and taught by the experimental group leader unit center, 40 subjects are randomly to the renal artery ablation with durg treatment group, 20 subjects to the drug treatment group). Sham-control research include 180 subjects, will be randomly assigned according to 2:1 (120 subjects in the renal artery ablation with drug treatment group and 60 subjects in the sham procedure with drug treatment group). Patients will be followed for blood pressure measurement and antihypertensive medication at 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, and 12 months after the procedure. Patients' urine samples will be collected for drug testing (LC-MS/MS) to determine their medication compliance in an independent laboratory.
