[Current perspectives in telemonitoring and devices in chronic heart failure patients: lights and shadows]

The complexity of an integrated approach, mandatory for chronic diseases such as heart failure, might be simplified by the availability of new technologies for remote data transmission at relatively low costs. Home telemonitoring for complex patients opens new perspectives for the safe discharge of chronically severe patients and intensive surveillance for unstable subjects, and shows potential benefits on patients' quality of life and cost containment. Systematic reviews and meta-analyses document a 30-35% decrease in mortality and a 15-20% reduction in hospital admissions. Critical issues remain the presence of health facilities and professionals both in hospital and in the community adequately prepared for patient management through the telemonitoring tool, the selection of patients who may benefit most from it, and financial reimbursement of remote monitoring. The main indication to telemonitoring is the patient at high risk of short-term hemodynamic deterioration, but psychosocial issues should also be considered. New perspectives for tailored management of heart failure patients come from the recent availability of implantable devices able to record hemodynamic parameters. Current evidence is, however, insufficient to affirm their reliability, efficacy, cost-effectiveness, and management changes that may derive from their use.
