Key result
The interaction between systolic blood pressure and the ACE D allele was significantly associated with increased carotid intima-media thickness (p=0.005), whereas the ACE genotype alone was not.

Does the interaction between ACE gene polymorphism and systolic blood pressure affect carotid intima-media thickness in patients with risk factors for atherosclerosis?
Effect estimate: F=7.915
p-value: p=0.005
The ACE gene D allele interacts with systolic blood pressure to augment carotid atherosclerosis, suggesting that high blood pressure is a genotype-specific risk factor for cardiovascular disease.
Kawamoto et al. (2002) conducted a cross-sectional in Carotid Atherosclerosis (n=184). Systolic blood pressure and ACE gene I/D polymorphism interaction vs. ACE II genotype was evaluated on Carotid intima-media thickness (IMT) (F=7.915, p=0.005). The interaction between systolic blood pressure and the ACE D allele was significantly associated with increased carotid intima-media thickness (p=0.005), whereas the ACE genotype alone was not.
