Objective: to evaluate the possibilities and effect of telemedicine monitoring and management of patients with CHF (compared to patients with CHF without intensive telemedicine monitoring) on quality of life, prognosis and the presence of complications and hospitalisations.~Patients with a stable form of congestive heart failure will be gradually included in the study. Half of them will be defined by random selection to intervention group. Parameters, that can be measured at home will be periodically telemedical monitored. In according with at home monitored data, the own physician will be able to intervene with change of medical treatment in the case of non-physiological deviations in order to improve the health status as well as the prognosis of the patient with CHF.
