Abstract
Background
Current genetic association studies have reported conflicting results regarding the association between miRNA polymorphisms and myocardial infarction (MI) risk
Methods
Relevant studies were retrieved from the PubMed, EMBASE, ISI Web of Science, and Scopus databases. Eligible studies determining the association between miRNA polymorphisms and MI susceptibility were included and a meta-analysis was performed to quantify the associations between miRNA polymorphisms and MI risk.
Results
A total of eight studies with 2507 MI patients and 3796 healthy controls were included, dealing with nine miRNA genes containing 11 different loci, including miR-149 (rs71428439 and rs2292832), miR-126 (rs4636297 and rs1140713), miR-146a (rs2910164), miR-218 (rs11134527), miR-196a2 (rs11614913), miR-499 (rs3746444), miR-27a (rs895819), miR-26a‑1 (rs7372209), and miR-100 (rs1834306). miR-146a rs2910164 and miR-499 rs3746444 were determined to have a significant association with MI susceptibility, a finding that was supported by the meta-analysis (rs2910164: GG/CC, odds ratio [OR]: 1.40, 95% confidence interval [95% CI]: 1.05–1.74, p < 0.001; rs3746444: AA + AG/GG, OR = 2.04, 95% CI: 1.37–2.70, p < 0.001). Limited or conflicting data were found for the relationship between the other miRNA polymorphisms (rs71428439, rs4636297, rs1140713, rs11134527, rs11614913, rs895819, rs7372209, rs1834306, rs2292832) and MI risk.
Conclusion
There was a significant association between rs2910164 and rs3746444 and MI susceptibility. Further studies are required to investigate the role of miRNA polymorphisms in MI risk.
