The WISH-trial is an open-label, parallel-group, randomized controlled trial. The effects of self-measuring of the blood pressure at home and the use of a pro-active web-based feedback system on the blood pressure, number of antihypertensive drugs used, and surrogate cardiovascular markers during a 12 month period will be investigated.

Arms Assigned Interventions
No Intervention: Control group.
Control group.
Experimental: Telecare, self monitoring, lifestyle counseling
Patients in the intervention group will measure their blood pressure with home blood pressure monitor which is linked to a secured website. Patients will measure as recommended in the European guidelines of hypertension. This includes 2 measurements in the morning and two times in the evening on 7 consecutive days every month. The measurements of the first day will be discarded. These measurements will be forwarded to the web-based system, which will be managed by the nurse practitioner and the research doctor. At least every month patients are contacted about the state of their condition. If needed, antihypertensive medication is added of adjusted by the nurse practitioner or research doctor under the supervision of one consultant physician. Tailored lifestyle advices are given every month.
Other: Telecare, selfmonitoring, lifestyl behaviour
Patients measure their own bloodpressure and the results are shown at a secured website after USB connection of the monitor to the computer. Patients receive medication adjustments and lifestyle advices via this secured website.
