Heart failure poses a large burden on patients and healthcare, largely because heart failure patients have low fitness and require frequent hospitalisation for close monitoring. In CardiacCare@Home, researchers work together with patients, doctors, industry, and others to develop technology for home-based monitoring of cardiac function and rehabilitation. This approach facilitates early detection of worsening of cardiac function, which allows doctors to rapidly alter treatment and prevent hospitalisation. Moreover, home-based rehabilitation will improve patients’ fitness levels. Technological innovations will facilitate a new care path that improves patients’ quality of life and lower socio-economic costs, and lower burden for hospital staff.
