An interactive web system with the help of your mobile phone can be an effective tool for better blood pressure control according to a new study. Test persons lowered their blood pressure and were better able to understand how their lifestyle affects their blood pressure and actively participated in followup discussions. These results were shown in a doctoral thesis at the University of Gothenburg. Well controlled blood pressure reduces the risk for cardio-vascular complications. In addition to taking daily medication persons with high blood pressure need to understand the sometime complicated connection between the blood pressure values and daily life.
