Digital Health, Wearable Technologies, and Artificial Intelligence in Cardiology

This chapter reviews the transformative impact of digital technologies on cardiovascular medicine, encompassing wearable biosensors, implantable remote monitoring systems, consumer-grade cardiac rhythm devices, and mobile health applications in the detection, management, and follow-up of cardiovascular conditions. It critically evaluates the clinical validation evidence for digital diagnostics, the regulatory landscape governing their adoption, and the challenges of data integration, algorithm transparency, and health equity. The chapter further examines artificial intelligence applications in risk prediction, clinical decision support, drug discovery, and the emerging vision of a continuously learning cardiovascular healthcare system.
