Brief Summary:
This trial is designed to establish invasive and non-invasive measures of arterial stiffness as potential predictors of treatment response to renal sympathetic denervation

Condition or disease Intervention/treatment Phase
Therapy Resistant Arterial Hypertension Device: Renal sympathetic denervation (RDN) Not Applicable

Detailed Description:
Regardless of the ongoing debate on the general effect of renal sympathetic denervation in therapy resistant hypertension, all trials published so far face the problem of a certain proportion of nonresponders to treatment. Previous data shows, that to some extent this might be attributable to arterial stiffening. Elevated invasive pulse wave velocity as an established marker for arterial stiffness has been found to be associated with nonresponse to renal denervation treatment in a smaller trial population. This trial attempts to assess the predictive value of different invasive and non-invasive markers for arterial stiffness in an adequately powered population.

Primary Outcome Measures :
  1. Predictive value of noninvasive and invasive measures of arterial stiffness (Pulse wave velocity and central pulse pressure assessed invasively, with a piezoelectric device and MRI-based) [ Time Frame: 3 Months ]
    AUC of ROCs for noninvasive and invasive measures of arterial stiffness in predicting response to renal denervation


Secondary Outcome Measures :
  1. Change in 24h ambulatory blood pressure [ Time Frame: 3 months, 6 months, 12 months ]
  2. Change in exercise blood pressure [ Time Frame: 3 months ]
  3. Predictive value of MRI-assessed aortic distensibility on Change in daytime ambulatory blood pressure [ Time Frame: 3 months, 6 months, 12 months ]
  4. Predictive value of MRI-assessed aortic distensibility on Change in 24 h ambulatory blood pressure [ Time Frame: 3 months, 6 months, 12 months ]
  5. Predictive value of MRI-assessed total arterial compliance on Change in daytime ambulatory blood pressure [ Time Frame: 3 months, 6 months, 12 months ]
  6. Predictive value of MRI-assessed total arterial compliance on Change in 24 h ambulatory blood pressure [ Time Frame: 3 months, 6 months, 12 months ]
  7. comparison of predictive value of invasive pulse wave velocity, invasive central pulse pressure, noninvasive pulse wave velocity, noninvasive central pulse pressure, aortic distensibility, total arterial compliance for Change in ambulatory blood pressure [ Time Frame: 3 months, 6 months, 12 months ]
