Patients with the heterozygote rs7069102 CG genotype tended to undergo anterior myocardial infarction (71.4%) more frequently than other myocardial infarction types (61.5%) (p=0.068, nearly significant) without differences in SIRT1 and endothelial nitric oxide synthase expression between both groups. Here, NOS3 is linked to myocardial infarction.
