Arms Assigned Interventions
No Intervention: UC
Usual HF guideline-base care
Experimental: TM
Telemonitoring group plus usual guideline-based HF care
Other: Telemonitoring
Participants in the intervention group are instructed to make a daily toll-free call to an automated telemonitoring system being provided by Pharos Innovations® (Chicago, IL) for 6 months.On each call patients hear a pre-recorded voice that goes through a series of questions about symptoms and the patient's daily weight. Information from the telemonitoring system is automatically downloaded to a secure Internet site for review by clinicians at each practice site.
