Usefulness of Wearable Devices for Monitoring Motor Activity in Patients with Early Myocardial Infarction

Abstract

Objective: The rising incidence of myocardial infarction (MI) in individuals under 50 years underscores an urgent need for innovative rehabilitation strategies that extend beyond hospital care, empowering young patients to reclaim active lives through sustained physical activity and remote monitoring. Wearable health technologies hold transformative potential here, as studies demonstrate their ability to boost exercise capacity, daily steps, and reduce rehospitalizations in post-MI recovery. This study thus assesses the clinical value of wearable devices in remotely tracking motor activity among young adults during early MI rehabilitation. Methods: Using the SiDLY Care Pro wristband, continuous non-invasive measurements of heart rate, oxygen saturation, and physical activity were collected from 62 of 80 post-MI patients (<50 years) over seven days, alongside validated questionnaires (IPAQ, SF-36, DASS-21). Time-series clustering and principal component analysis characterized heart rate dynamics and activity patterns. Most participants showed sedentary behaviour (2,000–4,000 steps/day), though self-reported health and psychological well-being were satisfactory. Results: The device provided reliable, clinically meaningful data, particularly when linked to clinician feedback. Participants expressed interest in using such technologies, especially if supported by reimbursement and professional guidance. Despite limitations—short monitoring, small heterogeneous samples, and accuracy constraints—the findings suggest wearable systems can enhance remote monitoring, patient engagement, and early intervention in post-MI care. Broader studies and supportive policies are recommended. Conclusion: Overall, integrating wearable technologies with professional oversight and patient participation may substantially improve recovery and outcomes for young MI survivors.
