Investigation and Validation of a Study Project on Digital Therapy Management of Patients With Arterial Hypertension

Inclusion Criteria: * ≥ 18 years of age * Existing diagnosis of arterial hypertension according to ICD-10 I10.- to I13.-, i.e. presence of the disease is recorded at the time of inclusion in the study. * Blood pressure at the time of inclusion is ≥130 mmHg systolic (24h mean) at 24h blood pressure measurement or, alternatively, at-home blood pressure measurement at ≥135 mmHg systolic (mean of 7 days). In case of the presence of a 24-h blood pressure measurement, this value is decisive compared to the at-home measurement. * Possession and use of a smartphone that allows the installation and use of "iATROS", whereby "use" implies that the patient possesses the physical and mental abilities to use and apply the iATROS app Exclusion Criteria: * Lack of capacity to consent * \< 18 years of age * No use of a smartphone * Lack of the physical and mental abilities necessary to use the iATROS app, or generally to use so-called "apps" on a smartphone or tablet. * Tumor disease associated with a reduced life expectancy of less than 1 year * Immunosuppression * Advanced dementia * Any other disease associated with a reduced life expectancy of less than 1 year * Any disease/condition that limits participation in the program * Pregnant or breastfeeding patients * A secondary hypertension known to the patient (by history) * Blood pressure at inclusion is \>170mmHg systolic on 24h blood pressure measurement (24h mean) or, alternatively, the at-home blood pressure measurement is \>175mmHg …
