NOS3 and type 2 diabetes mellitus: We found a significant risk for AMI associated with the Asp298/Asp298 genotype compared to the wild type Glu298/Glu298 among patients with T2DM (HR 3.12 CI [1.49–6.56], p = 0.003) but no association between eNOS genotype and AMI in subjects without T2DM (HR 0.45 [0.18–1.11], p = 0.083).
