Telemonitoring tools have become essential in today’s healthcare, representing fundamental resources for chronic disease home management supporting early detection of clinical worsening with great reduction of hospitalization costs. Therefore the investigation of the patient compliance is a key enabling point. We aim to assess how patients with chronic coronary syndromes evaluate a telemonitoring device meant for ongoing health monitoring. Twenty-six patients used the device for a week and subsequently filled out a well-designed questionnaire. The survey questions were about the device’s ease of use, satisfaction levels, perceived effectiveness, and its influence on the patients’ healthcare experiences. This study emphasizes the significance of focusing on patient needs in telemedicine and the importance of addressing these concerns to improve telehealth interventions.
