Background: The overall utilization of cardiac rehabilitation (CR) is low despite its proven benefits in secondary prevention. Virtual reality (VR), a novel method of rehabilitation, may increase overall compliance. The purpose of this systematic review and meta-analysis is to synthesize evidence and report whether the addition of VR leads to an improvement in anxiety and functional capacity (FC) compared to standard CR. Methods: A comprehensive search strategy was used to search the online databases for the randomized controlled trials (RCTs) on VR-CR. Statistical analysis was performed using Stata SE version 17.0 (College Station, TX) and RevMan5. Results: A total of 747 study participants were part of 7 studies included in the meta-analysis. Three studies were part of the narrative synthesis. Anxiety showed significant improvement in VR-CR compared to standard CR (SMD −0.32, 95% CI −0.61, −0.03). There was no significant improvement in FC between VR-CR and the standard CR (SMD 0.077, 95% CI −1.24, 1.32). Conclusion: VR-CR significantly improved CR-related anxiety compared to standard CR. However, no significant improvement in FC was found in VR-CR compared to the standard CR. Further studies are needed to assess the impact of non-immersive and immersive VR on FC.
