“…While all studies of MMP-3 evaluated the 5A/ 6A promoter SNP, only two have evaluated other MMP-3 SNPs and in those the 5A/6A SNP was as good or better at risk stratification than the others. ( 22,23 ) Prior studies of MMP-3 have found increased risk associated with both the 5A ( 11,13,14,18,21,22 ) and the 6A ( 10,12,13,23,26,27 ) allele, or no association ( 19 ), but the phenotypes studied therein included MI ( 11,14,(21)(22)(23)27 ), CAD presence ( 23 ), CAD progression ( 10,12 ), coronary aneurysm ( 18 ), patient-reported symptoms and CAD history ( 19 ), cardiac events ( 13 ), and CAD score ( 14 ).…”
