Digital Technologies and Artificial Intelligence in Cardiac Rehabilitation

PURPOSE: This review explores the role and impact of digital technology in cardiac rehabilitation (CR), assessing its potential to enhance patient outcomes and address barriers to CR delivery. REVIEW METHODS: A comprehensive literature search was conducted using curated search terms to target CR studies using digital technologies as an adjunct to in-person CR or as part of remote (ie, asynchronous) or virtual (ie, synchronous audiovisual communication) formats. The literature search focused on studies that evaluated the implementation and efficacy of using digital technologies within CR. SUMMARY: Digital technology offers significant opportunities to improve CR by providing flexible and scalable solutions that can overcome traditional barriers to CR such as accessibility and capacity constraints. Remote or virtual CR delivery that incorporates digital technologies improves CR adherence and achieves similar improvements in exercise capacity when compared to in-person CR. While the majority of studies have focused on exercise, digital technologies are increasingly used to deliver comprehensive CR solutions as part of remote and virtual CR programs. However, challenges and gaps in the literature remain, such as the impact of digital literacy and promoting equitable CR access, particularly in high-risk and vulnerable populations. Further research needs to focus on longer term outcomes to evaluate the safety, efficacy, and cost-effectiveness of digital CR interventions. The potential of digital health to transform CR and reduce the burden of cardiovascular disease is substantial and warrants further investigation.
