PURPOSE: To investigate the association of matrix metalloproteinase-9 (MMP-9) and paraoxonase 1 (PON1) 192 polymorphisms with susceptibility to coronary artery stenosis (CAS) and the number of diseased vessels in patients with CAS. METHODS: The study population comprised 302 unrelated Iranian individuals, including 145 patients with CAS and 157 control subjects. Genotypes for MMP-9 and PON1 192 polymorphisms were determined by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). RESULTS: In our study, distributions of the TT genotype of MMP-9 and the RR genotype of PON1 192 were significantly higher in patients compared with healthy control subjects (P<0.05). Subsequent analysis demonstrated that a significant difference existed in the male (TT+TC vs. CC and RR+QR vs. QQ, P<0.01) but not in the female. The associations of these polymorphisms with the severity of stenosis were also evaluated, which according to results distribution of MMP-9 and PON1 192 genotypes were not significantly different compared with the severity of stenosis (P>0.05). CONCLUSIONS: The observation indicates that the polymorphisms in the MMP-9 and PON1 192 genes potentially play a role in the manifestation of coronary atherosclerosis but does not have any effect on the number of diseased vessels in Iran.
