Aim of the study was to investigate a new clinical medical system for treatment of hypertension with a clinical decision system,a smartphone patient app and a home blood pressure monitor.

Despite the extensive knowledge of the importance of treating and thus preventing complications of hypertension, the incidence of high blood pressure is increasing, and it is still the main cause of cardiovascular disease and premature death, partly due to deficiencies in preventive care and control of the disease in an aging world. Blood pressure values obtained by self-measurement at home (HBPM) have been shown to predict the cardiovascular prognosis equally well as or better than blood pressure values obtained in the clinic (CBPM) in several observational studies. Aim of the present study was to investigate a new clinical medical system for treatment of hypertension with a clinical decision system and a electronic health record, a patient app and a home blood pressure monitor. " The patient app and the doctor's record reflect each other and basically contain the same information. Doctors can treat their patients remotely and the patients are able to manage some health issues by themselves by using the applications. Some patients need the physical examination. We therefore included patients after a so-called triage step with medical questions.
