Abstract
Background and objective: Retinal vein occlusion (RVO) and acute myocardial infarction (MI) are significant vascular events that impact patient health and mortality. Both conditions share common risk factors, such as hypertension, diabetes, and atherosclerosis. This study investigated the potential connection between RVO and MI, particularly among younger individuals, to improve preventive measures and management protocols.
Method: A systematic review and meta-analysis were conducted, adhering to the PRISMA and MOOSE guidelines. Multiple databases, including PubMed, Scopus, MEDLINE, ScienceDirect, and ClinicalTrials.gov, were exhaustively searched until August 24, 2024. Studies were selected based on their reports of the association between RVO and MI risk. Quality assessment was performed using the Newcastle-Ottawa Quality Assessment Scale, and data were pooled using a random-effects model with hazard ratios and 95% confidence intervals.
Result: Twelve studies comprising 371,817 participants were included. Meta-analysis revealed a pooled hazard ratio of 1.324 (95% CI, 1.238-1.415), indicating a significant association between RVO and increased MI risk (p = 0.0001). Subgroup analysis for central retinal vein occlusion (CRVO) showed a hazard ratio of 1.691 (95% confidence interval [CI] 1.142, 2.502, p = 0.009) with moderate heterogeneity (I2 = 36%), whereas branch retinal vein occlusion (BRVO) yielded a non-significant hazard ratio of 1.167 (95% CI 0.843, 2.106, p = 0.444; I2 = 33%). Publication bias was identified (Egger's test, p = 0.036) and addressed through trim-and-fill adjustment, maintaining statistical significance.
Conclusion: Our meta-analysis shows a strong association between CRVO and a 69.1% increased risk of MI, while BRVO shows no significant correlation. Overall, RVO is linked to a 32.4% elevated risk of MI. Despite slight publication bias, adjusted analyses confirm reliability, indicating that improved cardiovascular monitoring for RVO patients, especially those with CRVO, is essential to mitigate MI risk.
