N2 - Although great progress has been made in reducing renarrowing of the lumen after stenting of coronary arteries, a considerable number of patients develop recurrent in-stent stenosis. Several studies suggest that neointimal proliferation is the crucial pathophysiological process underlying restenosis after stenting. The renin-angiotensin-aldosterone system (RAS) has been implicated in the development of neointimal hyperplasia. We tested the hypothesis that polymorphisms of the RAS genes are associated with recurrent in-stent restenosis (ISR). Coronary stent implantation was performed in 272 patients with clinical symptoms or objective signs of ischemia. At follow-up angiography 6 months after stenting, 81 patients (29.8%) revealed in-stent restenosis. These patients underwent balloon angioplasty and were scheduled for a further 6 months of follow up. One year after initial stenting of the coronary artery, 39 patients displayed no significant angiographic ISR, whereas 42 patients developed recurrent in-stent restenosis (RISR). The survey of specific functional polymorphisms of the RAS, namely the angiotensin-I converting enzyme (ACE) D/I, the angiotensinogen (AGT) T174M and M235T, and A1166C of the angiotensin-II receptor 1 (AGTR1), revealed that the incidence RISR in the high-risk cohort was not associated with any of the polymorphisms examined in this study.
