  Purpose

In Germany nearly half of the population present elevated values of blood pressure, with - as a result of lifestyle factors and a growing average age - further increasing numbers.

Consequences of arterial hypertension may be cardiovascular diseases, cerebrovascular events, and renal insufficiency. Thus, hypertension therapy focuses on the reduction of these complications.

The aims of the 3A-registry are the characterization of outpatients with hypertension, their diagnostic procedures and medical treatment (esp. with renin inhibitors), therapy compliance and success, clinical events, and an assessment of overall guideline adherence in the treatment of these patients.

Patients fulfilling the relevant criteria are enrolled and followed up by their general practitioner or medical specialist.

Primary Outcome Measures:
  • Efficacy of Hypertension Treatment on Systolic Blood Pressure (SBP) [ Time Frame: baseline and 1 year ]
    Relative change of systolic office blood pressure since baseline, i.e. SBP at baseline minus SBP after 1 year, the difference divided by the baseline value, multiplied by 100

  • Efficacy of Hypertension Treatment on Diastolic Blood Pressure (DBP) [ Time Frame: Baseline and 1 year ]
    Relative change of diastolic office blood pressure since baseline, i.e. DBP at baseline minus DBP after 1 year, the difference divided by the baseline value, multiplied by 100

  • Efficacy of Hypertension Treatment on Systolic Blood Pressure (SBP) [ Time Frame: Baseline and 2 years ]
    Relative change of systolic office blood pressure since baseline, i.e. SBP at baseline minus SBP after 2 years, the difference divided by the baseline value, multiplied by 100

  • Efficacy of Hypertension Treatment on Diastolic Office Blood Pressure (DBP) [ Time Frame: Baseline and 2 years ]
    Relative change of diastolic office blood pressure since baseline, i.e. DBP at baseline minus DBP after 1 year, the difference divided by the baseline value, multiplied by 100

  • Efficacy of Hypertension Treatment on Systolic Blood Pressure (SBP) [ Time Frame: Baseline and 3 years ]
    Relative change of systolic office blood pressure since baseline, i.e. SBP at baseline minus SBP after 3 years, the difference divided by the baseline value, multiplied by 100

  • Efficacy of Hypertension Treatment on Diastolic Blood Pressure (DBP) [ Time Frame: Baseline and 3 years ]
    Relative change of diastolic office blood pressure since baseline, i.e. DBP at baseline minus DBP after 3 years, the difference divided by the baseline value, multiplied by 100


Secondary Outcome Measures:
  • Therapy Adherence Regarding Drug Treatment [ Time Frame: Baseline and 1 year ]
    Percentage of patients not having changed the therapy group after 1 year (DRI, ARB/ACE-I, or No-RAS-I, referring to their therapy at baseline)

  • Therapy Adherence Regarding Drug Treatment [ Time Frame: Baseline and 2 years ]
    Percentage of patients not having changed the therapy group after 2 years (DRI, ARB/ACE-I, or No-RAS-I, referring to their therapy at baseline)

  • Therapy Adherence Regarding Drug Treatment [ Time Frame: Baseline and 3 years ]
    Percentage of patients not having changed the therapy group after 3 years (DRI, ARB/ACE-I, or No-RAS-I, referring to their therapy at baseline)

  • Adverse Events [ Time Frame: 1 year follow up ]
    Percentage of participants that experienced at least one adverse event during the first year of observation period

  • Adverse Events [ Time Frame: 2 years follow up ]
    Percentage of participants that experienced at least one adverse event during the first two years of observation period

  • Adverse Events [ Time Frame: 3 years follow up ]
    Percentage of participants that experienced at least one adverse event during the three years of observation period

  • Therapeutic Success of Hypertension Treatment on Systolic Blood Pressure (SBP) as Measured by 24-hour Blood Pressure Measurement [ Time Frame: Baseline and 1 year ]
    Relative change of ambulatory, systolic 24h BP means since baseline, i.e. 24h SBP means at baseline minus corresponding means after 1 year, the differences divided by the baseline value, multiplied by 100. Mean SBP of a patient was calculated as the arithmetic mean of automatically recorded SBP values over a contiguous period of 24 h.

  • Therapeutic Success of Hypertension Treatment on Diastolic Blood Pressure (DBP) as Measured by 24-hour Blood Pressure Measurement [ Time Frame: Baseline and 1 year ]

Mean DBP of a patient was calculated as the arithmetic mean of automatically recorded DBP values over a contiguous period of 24 h.
