Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject with age of 18 to 65 years old (include 65), male or female;
  • Subject with essential hypertension who has an office BP of ≥150/90mmHg and \<180/110 mmHg (both SBP and DBP meet the criteria), and an average SBP of ≥ 135mmHg measured by 24-hour ABPM, after taking ≥ 2 antihypertensive medications for ≥ 4 weeks;
  • Subject with the resting heart rate ≥70bpm, if not taking beta-blockers (this criterion does not apply to those taking beta-blockers);
  • Subject with confirmed diagnosis of essential hypertension;
  • Subject with or without accessary renal arteries;
  • Subject who has signed the informed consent form, agrees to participate in this clinical trial, and is willing to comply with the required follow-ups per the trial protocol.

You may not qualify if:

  • Subject who is pregnant, nursing or planning to become pregnant during the study;
  • Subject with the shape and structure of unilateral or bilateral renal artery that are not suitable for ablation procedure (renal artery stenosis more than 50%, renal aneurysm, renal artery abnormality, renal artery diameter \<4mm or treatable segment length \<20mm);
  • Subject who has unilateral kidney or kidney transplant;
  • Subject with a history of renal artery interventional therapy or renal denervation;
  • Subject with any conditions that may affect the accuracy of blood pressure measurement: such as the diameter of the upper arm is too large relative to the cuff, arrhythmia;
  • Subject with secondary hypertension;
  • Subject with pseudo-hypertension;
  • Subject with orthostatic hypotension;
  • Subject with eGFR \<45mL/min/l.73m2;
  • Subject with average SBP is \< 135mmHg on 24-hour ABPM;
  • Subject with a history of hospitalization for hypertensive emergency within past one year;
  • Subject with type I diabetes mellitus;
  • Subject with primary pulmonary hypertension;
  • Subject with a history of bleeding diathesis and hematological disorders;
  • Subject with a history of embolism within past 6 months;
  • +20 more criteria
