Study summary

The purpose of this study is to estimate the proportion of patients with "true" resistance among patients referred to the Medical Outpatient Department of the Charité - Universitätsmedizin Berlin with the diagnosis "resistant hypertension". Moreover, data on medication adherence will be collected based on therapeutic drug monitoring and on the answers to validated questionnaires. Finally, efficacy, safety and costs of renal sympathetic denervation will be compared to an intensified drug treatment in an exploratory way.

What researchers measure

Primary outcomes

  1. Estimation of the proportion of patients with "true" resistance among patients referred to the Medical Outpatient Department of the Charité - Universitätsmedizin Berlin with the diagnosis "resistant hypertension"

    Time frame: Week 6

Secondary outcomes

  1. Assessment of all costs of both treatments within one year.

    Time frame: During the whole course of the study (24 weeks) and for another 24 weeks after the end of the study

  2. Analysis of medication adherence at baseline, after fixed-dose triple combination treatment and in the end of the study via therapeutic drug monitoring, and correlation of these results with the questionnaire findings.

    Time frame: Baseline, week 6, end of study on week 24

  3. Explorative evaluation of the efficacy of renal sympathetic denervation compared to an intensified drug treatment based on ambulatory blood pressure and ambulatory blood pressure measurement over 24 hours.

    Time frame: Week 6 - week 24

  4. Assessment of adverse events in order to evaluate the safety of both treatments.

    Time frame: During the whole course of the study (24 weeks)
