Effect of Renal Denervation in End Staged Renal Disease With Resistant Hypertension

Effects of Catheter Based Renal Sympathetic Denervation on Resistant Hypertension in End Stage Renal Disease in Korea

A. Hypertension is a major cardiovascular risk factor and numerous treatment strategies have been developed to treat hypertension properly and reduce cardiovascular risk.

B. However, there is a subgroup of hypertension which are resistant to treatment.

1. Resistant hypertension is associated to sympathetic hyperactivity
2. Renal sympathetic nerve is known to be associated with systemic sympathetic activity
3. According to research of recent years, catheter based renal sympathetic denervation is a safe and effective treatment modality to treat resistant hypertension C. Resistant hypertension is observed in end stage renal disease (ESRD) frequently.

D. Sympathetic hyperactivity is observed in ESRD patients E. Catheter based renal sympathetic denervation is expected to improve resistant hypertension in ESRD patients

F. The aim the present study is to evaluate the effects and safety of catheter based renal sympathetic denervation on resistant hypertension in ESRD

Inclusion Criteria:

• Patients who are under hemodialysis due to end stage renal disease
• Patients who have resistant hypertension with office SBP >160 mmHg)
• Patients who are or over 18 years old.
• Patients who submit informed consent

Exclusion Criteria:

• Known secondary hypertension patients

• Patients who have renal artery which is not adequate for renal denervation

  1. The main renal artery diameter < 4 mm, or renal artery length < 20 mm
  2. The renal arteries into which stable catheter insertion is difficulty and which have hemodynamically or anatomically significant stenosis
  3. The renal arteries who have undergone renal angioplasty

• Patients who have history of myocardial infarction, unstable angina, syncope cerebrovascular insufficiency or extensive atherosclerotic disease with intravascular thrombosis, or unstable plaque

• Type 1 Diabetes

• Patients who have scheduled percutaneous coronary intervention (PCI) or operation within 6 months

• Hemodynamically significant valvular heart disease in which blood pressure reduction may cause significant deterioration of patient's health.

• Primary pulmonary hypertension

• Patients who have the intracardiac defibrillator(ICD) or pacemaker which do not allow delivery of radiofrequency energy.

• Patients who require continuous oxygen supply or mechanical ventilation for treatment of obstructive sleep apnea

• Patients who have serious medical condition which can compromise the safety of the patients and the safety and integrity of the study.

• Patients who have unresolved drug issue, alcoholism

• Patients who lack ability to understand and follow the instruction the researcher

• Patient who cannot follow up
