From Cath Lab to Cloud: A Scoping Review on Telehealth and Remote Monitoring in Post-PCI Patient

Background : Percutaneous coronary intervention (PCI) is a cornerstone treatment for patients with coronary artery disease, but optimal recovery requires comprehensive secondary prevention strategies. Despite strong guideline recommendations, participation in conventional cardiac rehabilitation (CR) remains low due to logistical, socioeconomic, and accessibility barriers. The growing integration of telehealth, mobile health (mHealth), and remote monitoring technologies offers new opportunities to improve post-PCI care delivery, adherence, and outcomes. Objective : This scoping review aimed to map and synthesize existing research on the use of telehealth and remote monitoring interventions for patients following PCI, with a focus on implementation strategies, clinical outcomes, and patient engagement. Methods : Following the Joanna Briggs Institute (JBI) scoping review methodology, we conducted a structured search of PubMed and Google Scholar for English-language, peer-reviewed original research articles published between January 2020 and April 2025. Eligible studies involved human patients post-PCI and evaluated telehealth, telemedicine, or remote monitoring interventions. Review articles, protocols, non-English papers, and studies unrelated to PCI or telehealth were excluded. Screening and data extraction were independently performed by multiple reviewers. Results : From 191 initially identified records, 12 studies met the inclusion criteria. Interventions included mHealth applications, hybrid CR programs, wearable devices, structured teleconsultations, and remote disease management platforms. Reported outcomes included improvements in CR participation, medication adherence, physical activity, quality of life, and psychological well-being. Several studies demonstrated noninferiority of home-based or hybrid CR to traditional center-based models. Platforms incorporating interactive education, live coaching, or biometric feedback were particularly effective in sustaining patient engagement. However, heterogeneity in study design, short-term follow-up, and limited reporting of hard clinical endpoints remain common limitations. Conclusion : Telehealth and remote monitoring interventions show strong potential to enhance post-PCI care by addressing barriers to traditional rehabilitation and enabling personalized, accessible follow-up. Although findings are promising, future research should focus on long-term outcomes, scalability, and cost-effectiveness to inform broader integration into cardiovascular care models.
