• Subject who is participating in other drug or medical device clinical investigations

Other illness

• Subject with history of renal artery intervention (Percutaneous Transluminal Angioplasty \[PTA\] or stenting) or Renal Denervation (RDN)
• Subject with any conditions that may affect the accuracy of blood pressure (BP) measurement: such as the diameter of the upper arm is too large for the cuff, or arrhythmia, etc
• Subject with known secondary hypertension

• Subject with type I diabetes mellitus
• Subject with primary pulmonary hypertension
• Subject with history of bleeding diathesis and haematological disorders or coagulopathy

• Subject with a history of ventricular fibrillation or ventricular tachycardia
• Subject who is allergic to contrast agents and not responding to preventive medication
• Subject with acute or severe systemic infections
