Abstract

Digital health technologies have enhanced cardiac rehabilitation by enabling remote monitoring, personalized feedback and increased patient engagement. This retrospective study analyzed four years of medical records from patients using digital platforms, wearables and teleconsultations. Those using digital tools showed higher adherence, better functional gains and improved risk factor control than those in traditional care. Remote monitoring allowed for earlier detection of clinical changes and timely treatment adjustments, reducing hospital readmissions. Data highlight digital health’s potential to expand access and improve long-term outcomes in cardiac care.
