AIMS: To provide a quantitative analysis of eHealth-supported interventions on health outcomes in cardiovascular rehabilitation (CR) maintenance (phase III) in patients with coronary artery disease (CAD) and to identify effective behavioral change techniques (BCTs).; METHODS: A systematic review was conducted (PubMed, CINAHL, MEDLINE, Web of Science) to summarize and synthesize the effects of eHealth in phase III maintenance on health outcomes including physical activity (PA) and exercise capacity, quality of life (QoL), mental health, self-efficacy, clinical variables, and events/rehospitalization. A meta-analysis following the Cochrane Collaboration guidelines using Review Manager (RevMan5.4) was performed. Analyses were conducted differentiating between short-term (≤6 months) and medium/long-term effects (>6 months). BCTs were defined based on the described intervention and coded according to the BCT handbook.; RESULTS: Fourteen eligible studies (1,497 patients) were included. eHealth significantly promoted PA (SMD=0.35; 95%CI 0.02--0.70; p=0.04) and exercise capacity after 6 months (SMD=0.29; 95%CI 0.05-0.52; p=0.02) compared to usual care. QoL was higher with eHealth compared to care as usual (SMD=0.17; 95%CI 0.02-0.32; p=0.02). Systolic blood pressure decreased after 6 months with eHealth compared to care as usual (SMD=-0.20; 95%CI -0.40-0,00; p=0.046). There was substantial heterogeneity in the adapted BCTs and type of intervention. Mapping of BCTs revealed that self-monitoring of behavior and/or goal setting, as well as feedback on behavior were most frequently included.; CONCLUSION: eHealth in phase III CR is effective in stimulating PA and improving exercise capacity in patients with CAD, while increasing QoL and decreasing systolic blood pressure. Currently, data of eHealth effects on morbidity, mortality, and clinical outcomes are scarce and should be investigated in future studies. PROSPERO, CRD42020203578. © The Author(s) 2023.
