Immersive virtual reality reduces depression, anxiety and stress in patients with cardiovascular diseases undergoing cardiac rehabilitation: A systematic review with meta-analysis.

BACKGROUND

Current literature suggests that immersive virtual reality (IVR) could be an efficacious therapeutic approach for patients with cardiovascular diseases (CVD) undergoing cardiac rehabilitation program (CRP). However, this has only been affirmed in individual studies and is yet to be confirmed by a systematic review.

OBJECTIVES

To determine the efficacy of IVR interventions on depression, anxiety, and stress symptoms in patients with CVD.

METHODS

A meta-analysis was performed in line with PRISMA guidelines following a literature search between inception and June 2024 in PubMed, SCOPUS, WOS, CINAHL and PEDro for retrieving randomized controlled trials (RCTs) that compared the efficacy of IVR versus conventional CRPs on depression, anxiety and stress in patients with CVD. The PEDro scale was used to evaluate the methodological quality of the studies. Pooled effects were calculated using the Cohen's standardized mean difference (SMD) and its 95% confidence interval (95% CI), or mean difference (MD) if studies used the same measure.

RESULTS

Eight RCTs, providing data from 510 patients with CVD (63.8±5.4 years, 60% men), were included. The methodological quality was moderate (M=5.1±1 points). A large rehabilitative effect of IVR was found for reducing depression (SMD=-0.54; 95% CI -0.77 to -0.31; p<0.001), anxiety (SMD=-0.43; 95% CI -0.74 to -0.12; p=0.006) and stress (MD=-14.96; 95% CI -20.1 to -9.8; p<0.001). The findings suggest that combine IVR and CRP is the most appropriate approach for reducing depression, anxiety and stress.

CONCLUSION

IVR, especially when combined with a traditional CRP, reduces depression, anxiety and stress in patients with CVD.
