BACKGROUND: Chromosome 9p21 single nucleotide polymorphisms (SNPs) have been shown to be associated with coronary heart disease in multiple studies. The aim of the present study was to identify whether these SNPs are associated with recurrent myocardial infarction (MI), revascularization, or death in acute coronary syndrome (ACS) patients or in those undergoing coronary artery bypass grafting (CABG).
METHODS AND RESULTS: TexGen registry participants with ACS (n=2,067) or CABG (n=1,176) were evaluated, to assess whether 9p21 SNPs (rs1333049, rs2383206, rs10757278, rs10757274) were associated with recurrent MI (primary outcome), recurrent revascularization, or death (secondary outcomes) at approximately 3.2 years of follow-up. Carriers of risk allele (C) for rs1333049 presented at an earlier age (62 vs. 63.5 years in non-carriers, P=0.0004) with more extensive disease (number of vessels with significant stenosis: 1.9 vs. 1.7 in non-carriers, P=0.001) in the ACS group. In adjusted models, the C allele was not associated with recurrent MI (hazard ratio [HR], 1.01; 95% confidence interval [CI]: 0.74-1.38), recurrent revascularization (HR, 0.98; 95%CI: 0.78-1.23), or death (HR, 0.91; 95%CI: 0.69-1.18) in the ACS or CABG groups (recurrent MI: HR, 0.64; 95%CI: 0.40-1.05; recurrent revascularization: HR, 0.98; 95%CI: 0.61-1.55; death: HR, 0.89; 95%CI: 0.61-1.30). Results were similar for the other 3 SNPs.
CONCLUSIONS: 9p21 SNPs were not associated with recurrent MI, revascularization, or mortality after ACS or CABG. Individuals with the rs1333049 C allele, however, may present with earlier and more extensive disease.
