Hospitalisation for acute decompensated heart failure (ADHF) leads to physical and physiological deconditioning. Cardiac (tele)rehabilitation (CTR) is essential to improve quality of life (QoL), physical functional capacity and reduce the risk for (re)hospitalisation in patients with CHF. The purpose of this interim analysis was to evaluate the eff...

Aims Telemonitoring strategies in heart failure (HF) patients are often based on manual readings of multiple parameters by the healthcare professional (HCP). In order to improve early prediction of decompensated HF, and to reduce the workload for both the HCP and the patient, there is a need for multiparameter predictive models. These models should...

Population aging is arguably one of the most serious challenges facing human society. It is not only a severe crisis in the developed world but also a rigorous threat to emerging economies. Therefore, vigorous measures need to be taken to mitigate the impact of aging society. This chapter proposes a procedure model as the foundation to systematical...
