  • Title: Genetic Polymorphism of Matrix Metalloproteinase-9 and Susceptibility to Myocardial Infarction: A Meta-Analysis.
    Author: Feng B, Li H.
    Journal: Dis Markers; 2022; 2022():5507153. PubMed ID: 35075377.
    Abstract:
    OBJECTIVE: Current findings on the association between MMP-9 rs3918242 and susceptibility to myocardial infarction (MI) are inconsistent, and their definite relationship is discussed in this meta-analysis. METHODS: Eligible literatures reporting MMP-9 rs3918242 and susceptibility to MI were searched in PubMed, Cochrane Library, CNRI, and VIP using keywords such as "MMP-9", "matrix metallopeptidase-9" and "myocardial infarction", "acute myocardial infarction", "AMI", and "polymorphism". Data from eligible literatures were extracted for calculating OR and corresponding 95% CI using RevMan 5.3 and STATA12.0. RESULTS: Ten independent literatures reporting MMP-9 rs3918242 and susceptibility to MI were enrolled. Compared with subjects carrying CT&TT genotype of MMP-9 rs3918242, susceptibility to MI was lower in those carrying CC genotype (OR = 1.49, 95%CI = 1.19-1.86, P = 0.0004). Such a significance was observed in the overdominant (OR = 1.27, 95%CI = 1.14-1.41, P < 0.0001) and allele genetic models (OR = 1.43, 95%CI = 1.17-1.74, P = 0.0005) as well. This finding was also valid in the Asian population. CONCLUSIONS: Mutation on MMP-9 rs3918242 has a potential relevance with susceptibility to MI.
