ACE gene and CAD

ACE gene and CAD

ACE gene and CAD: Patients with a homozygous deletional form of the ACE gene (dd) have increased circulating ACE level and hence are more likely to develop myocardial infarction [1].

Myocardial levels of ACE (angiotensin converting enzyme) are higher in patients with the dd gene [2].

Quinapril prevents restenosis after stenting in patients with ACE D allele [3]. Higher minimal luminal diameter (MLD) lower diameter stenosis (22.9 vs 37.1 %, p < 0.05) was noted in patients with the D allele although there was no difference in those with the II genotype.

Intravascular ultrasound (IVUS) documented the prevention of loss of MLD in patients with the D allele compared to those with the II genotype. It was concluded that attenuation of lumen loss of the implantation of a coronary stent was better in those with D allele of the ACE gene [3].
