Resumen:
Several studies have demonstrated that matrix metalloproteinases (MMPs) play a major role in atherosclerotic plaque disruption and lead to myocardial infarction (MI). We investigated the association between the MMP1 -1607 1G/2G (rs1799750), MMP3 -1612 5A/6A (rs3025058), and MMP9 -1562 C/T (rs3918242) polymorphisms and the risk of developing MI in a Mexican mestizo cohort. The genotype analysis was performed using the restriction fragment length polymorphism-polymerase chain reaction technique in a group of 236 patients with a history of MI and 285 healthy controls. Similar distributions of rs1799750 and rs3025058 were observed in both groups; however, the MMP9 rs3918242 T allele and the CT genotype were associated with the risk of developing MI (OR = 2.32, pC = 0.02 and OR = 2.40, pC = 0.02, respectively). Multiple logistic analysis was performed between MI patients and controls to estimate the risk, and after adjusting for identified risk factors, the CT + TT genotypes of MMP9 rs3918242 were found to be significantly associated with increased risk of developing MI than those with the CC genotype (OR = 2.88, P < 0.01). In summary, our results reveal that the rs3918242 polymorphism of the MMP9 gene plays a major role in the risk of developing MI. © FUNPEC-RP.
