Renal Denervation for Resistant Hypertension

Patient Selection and Recommendations

  • The European Society of Cardiology recommends Renal Denervation (RDN) as an adjunctive treatment option for patients with resistant hypertension who remain uncontrolled on a combination of three antihypertensive medications, including a diuretic, and have undergone a thorough risk-benefit discussion and multidisciplinary assessment 1, 2
  • RDN may be considered for patients with increased cardiovascular risk and uncontrolled hypertension on less than three medications, provided they have undergone a shared risk-benefit discussion and multidisciplinary assessment 3
  • The European Society of Cardiology does not recommend RDN as a first-line treatment for hypertension due to limited evidence on its safety and cardiovascular benefits 2, 3

Treatment Algorithm

  • The recommended treatment sequence for resistant hypertension includes:

Safety Considerations

  • RDN is not recommended for patients with moderate to severe renal impairment (eGFR <40 mL/min/1.73 m²) or secondary hypertension 2

Implementation Considerations

  • Suitable patients for RDN should have true resistant hypertension, defined as uncontrolled blood pressure on three antihypertensive medications, including a diuretic 1, 2
  • Before considering RDN, true treatment resistance should be confirmed, treatment adherence should be accurately assessed, and pseudo-resistance should be excluded 4
  • Factors contributing to treatment resistance, including secondary hypertension causes, should be identified 4
  • RDN should be performed in medium to high-volume centers to ensure procedural quality and safety 2, 3
  • Multidisciplinary assessment and shared risk-benefit discussion are required 2, 3
