Abstract
Home-based cardiac rehabilitation (HBCR) is expected to address the low participation rate in cardiac rehabilitation; however, it is not covered by insurance in Japan, and the optimal method for monitoring a patient's condition during exercise has not been determined. Patients hospitalized for heart failure often deteriorate soon after discharge and require appropriate disease monitoring. In this report, we describe cases in which real-time monitoring of exercise intensity, electrocardiography, and video chat during HBCR was useful in the management of heart failure. Furthermore, the use of HBCR enabled frequent disease monitoring, even during the coronavirus disease 2019 pandemic, and timely medicine adjustment. LEARNING OBJECTIVE: Clinicians cannot perform radiography, blood tests, or physical examinations at home during home-based cardiac rehabilitation (HBCR). Therefore, it is particularly important to reconsider the appropriate monitoring indicators for HBCR and apply them to disease management. Our cases suggest that real-time monitoring of the following three indicators is useful for disease management using HBCR: (1) exercise intensity, (2) electrocardiography, and (3) shortness of breath.
