In contrast to previous reports, homozygosity for the Asp298 variant of the 894G>T polymorphism in the eNOS gene was not found to be associated with risk of AMI, extent of CAD and in-hospital mortality after AMI.
Recent reports have suggested that the Glu298Asp polymorphism in exon 7 of the endothelial nitric oxide synthase gene is associated with coronary spasm and acute myocardial infarction.
