Abstract
We investigated a home-based intervention based on telecardiology in patients with chronic heart failure (CHF). Two hundred and thirty CHF patients, aged 59 years (SD 9), in stable condition and with optimized therapy were enrolled. The programme consisted of trans-telephonic follow-up and electrocardiogram (ECG) monitoring followed by visits from a paramedical and medical team. The patient could call the centre when required (tele-assistance), while the team could call the patient at pre-scheduled times (telemonitoring). During the first 12 months, there were 3767 calls (873 ad hoc and 2894 scheduled calls). There were 648 events, including 126 episodes of asymptomatic hypotension and 168 episodes which were not due to cardiological symptoms. No actions were taken by the nurse after 2417 calls (64%). A change in therapy was suggested after 418 calls, hospital admission in 62 patients, further investigations for 243 patients and a consultation with the general practitioner in 41 patients. A total of 2303 one-lead ECG recordings were received (10 per patient); 126 recordings (6%) were diagnosed as pathological in comparison with the baseline one. The one-lead ECG recording was used for titration of beta-blockers in 79 patients (mean dosage 38 mg vs 42 mg, P<0.01). Home telenursing could be an important application of telemedicine and single-lead ECG recording seems to offer additional benefit in comparison with telephone follow-up alone.
