    Abstract:
    OBJECTIVES: In this study, we investigated the association between matrix metalloproteinase-1 (MMP-1) G-1607GG, MMP-12 A-82G and MMP-12 A1082G genotypes and haplotypes and the prognosis of coronary artery disease (CAD). METHODS: A total of 129 Tunisian patients with CAD were followed prospectively for a median of 2.5 years. Genotypes were determined by a PCR-based restriction fragment length polymorphism. Two endpoints were considered: restenosis and incidence of clinical vascular events (restenosis, myocardial infarction, stroke, cardiac death). RESULTS: Genotypes of MMP-1 G-1607GG, MMP-12 A-82G and MMP-12 A1082G were not associated with the incidence of restenosis or clinical events. Analysis of haplotypes consisting of alleles of MMP-1 G-1607GG and MMP-12 A1082G showed that the rate of clinical events was significantly higher in patients carrying the GG-A haplotype than those with other haplotypes (0.637 vs. 0.424, respectively, odds ratio=1.45; 95% confidence interval=1.04-2.04; P<0.05; P adjusted for multiple risk factors). However, after Bonferroni correction for multiple comparisons, this difference did not reach statistical significance (P=0.093), showing that there was a tendency for the association between the GG-A haplotype and future clinical events in patients with CAD. CONCLUSION: These findings showed a trend of the GG-A haplotype of MMP-1 G-1607GG/MMP-12 A1082G towards the prediction of future clinical events in patients with CAD and suggested a possible importance of these loci in the prediction of the prognosis of CAD. Studies with large sample size are warranted to better investigate this association, as MMP genotyping could aid in identifying patients who are likely to have unfavourable prognosis.
