Heart failure is a chronic disease associated with an increasing risk of morbidity, disability, repeated hospitalizations and mortality. Telemedicine could promptly identify signs of worsening cardiac disease in order to improve elderly patients' home care and quality of life by reducing the need of hospital admissions and sanitary costs. The investigators present a randomized, parallel-group trial to test the ability of a multiparametric remote monitoring system, in addition to standard care, to promptly identify worsening of heart failure and prevent hospital admission and mortality.
