ACE I/D polymorphism in different etiologies of ischemic stroke

Objectives –  Data concerning an association between angiotensin‐converting enzyme ( ACE ) gene insertion/deletion (I/D) polymorphism and ischemic stroke (IS) remain inconsistent. Results of some studies suggest that DD genotype may be a risk factor for small vessel disease (SVD) stroke. Here, we investigated whether this polymorphism is associated with IS of different etiologies in a Polish population. Subjects and methods –  Ischemic stroke etiology was established according to the TOAST criteria. We studied 92 stroke patients with large vessel disease and their 184 matched controls; 96 stroke patients with SVD and 192 controls; 180 patients with cardioembolic stroke (CE) and 180 controls. ACE I/D polymorphism was determined using the polymerase chain reaction method. Results –  The distribution of ACE genotypes and alleles was essentially the same in all analyzed IS subtypes and their matched controls. Conclusions –  We failed to find an association between ACE polymorphism and etiological subtypes of IS in a Polish population.
