Résumé

<p><b>OBJECTIVE</b>To investigate the association of angiotensin-converting enzyme 2 (ACE2) gene polymorphisms and coronary artery disease (CAD) in patients with type 2 diabetes mellitus (T2DM).</p><p><b>METHODS</b>This study involved 121 patients with T2DM and 94 with diabetic macroangiopathy. The polymorphisms of G8790A in ACE2 gene was analyzed using PCR-restriction fragment length polymorphism analysis in these patients, and the clinical, biochemical and echocardiographic data were also analyzed.</p><p><b>RESULTS</b>No obvious difference was found in the genotyping data between the two groups. Among the male patients with diabetic macroangiopathy, the interventricular septal end-diastolic thickness (IVSTd) were significantly greater in patients of GG genotypes of ACE2 gene G8790A than in those of AA genotypes (P<0.01), and the left ventricular mass (LVMI) and urine protein were also significantly higher in GG genotypes (P<0.05). No similar results were found the uncomplicated diabetic group or the female diabetic patients with CAD.</p><p><b>CONCLUSION</b>The ACE2 gene G8790A polymorphism plays a role in the pathogenesis of CAD in patients with type 2 diabetes, suggesting that ACE2 genotyping is helpful to screen the susceptible patients.</p>
