The hazard ratio associated with the high-risk genotype (a homozygote of high risk for ACS or a heterozygote) was: HR = 2.2 (1.15-4.2) for the rs10757278 polymorphism, HR = 2.7 (95% CI 1.3-5.4) for the rs4977574 one and HR = 2.3 (1.2-4.5) for the rs1333049 one (Cox proportional hazards model).
The rs1333049, rs10757278 and rs4977574 are single nucleotide polymorphisms (SNPs) of chromosome 9p21 locus that are associated with prevalence of acute coronary syndromes (ACS).
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.
