Renal Sympathetic Denervation and Insulin Sensitivity (RENSYMPIS Study) (RENSYMPIS)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified February 2013 by The Hospital District of Satakunta.
Recruitment status was:  Recruiting

Hypertension is a major risk factor for stroke and cardiovascular mortality. Catheter- based renal denervation causes substantial and sustained blood- pressure reduction in patients with resistant hypertension.

The purpose of RENSYMPIS is to study the effects of renal denervation on:

  1. Cardiovascular function
  2. Metabolic factors
  3. Inflammatory and endocrine factors
  4. Coagulation
  5. Sleep

Condition Intervention
Resistant Hypertension Procedure: Renal Denervation

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Further study details as provided by The Hospital District of Satakunta:
