ABSTRACT
<p><b>OBJECTIVE</b>To investigate the association between acute coronary syndrome (ACS) and functional matrix metalloproteinase-9 polymorphism (C-1562-T).</p><p><b>METHODS</b>This study was conducted with a case-control design including 101 patients with angiographically documented ACS and 105 control subjects who were free from coronary artery disease and had normal angiograms. Genotype was determined by polymerase chain reaction-restriction fragment length polymorphism for the common C-1562-T functional promoter polymorphism of the MMP-9 gene.The relationship between the polymorphism in the MMP-9 gene and the severity of coronary arterial stenosis was analyzed.</p><p><b>RESULTS</b>The results of individual polymorphisms analysis showed that the frequency of C/T and T/T genotypes of the C-1562-T polymorphism (27.2%) in patients with ACS was significantly higher than that in those with a normal angiogram (13.34%).The frequencies of -1562T allele were 14.9% and 7.2% in ACS group and control group respectively (Chi2 = 5.617, P = 0.018). The frequencies of C/T and T/T genotypes of the C-1562-T polymorphism were not statistically different among ACS patients with normal and one,two,three or more significantly diseased vessels (Chi2 = 0.601, P = 0.896).</p><p><b>CONCLUSION</b>The present findings suggest that the genetic polymorphism in MMP-9 promoter (C-1562-T) is associated with the susceptibility to ACS in the Han population of China. And the C-1562-T polymorphism may not be useful as a predictor of the severity of coronary atherosclerosis.</p>
