This article refers to ‘Effects of an outpatient intervention comprising nurse-led non-invasive assessments, telemedicine support and remote cardiologists’ decisions in patients with heart failure (AMULET study): a randomised controlled trial’ by P. Krzesi´nski et al. , published in this issue on pages 565–577. When considering telemedicine in heart failure (HF), we have in mind remote patient monitoring with a daily transfer of vital parameters from patient’s home to caregivers. The main purpose of this approach is the prevention of HF hospitalizations due to early detection of a cardiac decompensation and an immediate response. The concept of home telemonitoring was investigated in several randomized controlled trials (RCTs) using different invasive and non-invasive devices. The results of these RCTs are inconsistent ( Table 1 ). AMULET was a multicentre, prospective, randomized, open-label, controlled, parallel group trial investigating the efficacy of a telecare model based on nurse-led outpatient service at so-called ‘ambulatory care points’ (ACPs). 1 0 The study was per-formed in nine sites in Poland between March 20 1 8 and October 2020. The basic concept of the AMULET telecare model is a nurse-led HF outpatient service combined with telemedical support by a cardiologist. The nurses assessed HF signs and symptoms during seven outpatient visits during 1 2months of follow-up at the ACP. During these visits, additional vital parameters – heart rate, blood pressure, thoracic fluid content, body mass and total body water –
