• Patients with diabetes mellitus (DM) have advanced atherosclerosis compared with nondiabetics. Restenosis after intracoronary stent implantation occurs frequently in diabetic patients. Angiotensin II is an important growth factor for the development of neointimal hyperplasia after vascular injury. The aim of our study was to evaluate the relationships between angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and coronary artery disease (CAD) and stent restonosis in diabetic patients. One hundred and thirty consecutive patients with CAD and 47 consecutive patients (14 males, mean age, 58.0 ± 10.0) without CAD were enrolled in the study. All patients had type 2 (noninsulin dependent) DM. The patients with CAD underwent percutaneous transluminal coronary angioplasty (PTCA) and stenting. Ninety-four (59 males, mean age, 60.3 ± 9.8) underwent control coronary angiography at the end of the follow-up period (mean duration, 9.1 ± 2.9 months). ACE gene I/D genotyping was identified in all patients. No significant difference was found among patients with and without CAD with respect to ACE gene I/D polymorphism (P = 0.460). In the control coronary angiography, stent restenosis and new lesion development were comparable in each genotyping subgroup. However, a significant relationship was observed between restenosis and the use of ACE inhibitors (ACEI) in patients with D allele (ACEI ratio, 43.5% in the restenosis group and 56.5% in non-restenotic group, P < 0.05). We did not find any relationship between ACE gene I/D polymorphism and CAD and stent restenosis and new lesion development in diabetic patients. On the other hand, ACEI treatment may reduce stent restenosis in type 2 diabetic patients with D allele (DD or ID).
