In the last years the development of home based e-health applications, which use information, telecommunication and videoconferencing technologies, is increased because of their characteristics that allow reducing hospitalization costs and managing and monitoring patient health in real time. However, the development of a home based e-health monitoring system requires the contribution of different expertise, from medicine to engineering, and technologies, from Electronics to Medical Informatics and Telemedicine. Here we illustrate a home based e-health project that has been developed with the cooperation of several different research groups of the Bioengineer Department of the "Politecnico di Milano". They provided and integrated all required knowledge and background, including Biomedical Electronics and Biosensors, Biosignal Processing, Medical Informatics and Telemedicine, and Information and Communication Technologies. The aim of the discussed work was to design and implement a Web application that enables different healthcare actors to insert and browse healthcare data, bio-signals, and biomedical images of patients enrolled in a program of cardiovascular risk prevention. Such application is intended to be part of a home monitoring system to be used during the home physical training program of cardiovascular risk patients.
