Neointimal hyperplasia (NIH) has a central role in stenosis and thrombosis development, which represent the most frequent causes of vascular access failure. Polymorphism of different genes that have a significant role in endothelial function may have an impact on NIH development. Therefore, the aim of our study is to determine the effect of angiotensin-converting enzyme (ACE) I/D and matrix metalloproteinase-3 (MMP3) 5A/6A polymorphism on risk for developing vascular access failure in hemodialysis patients. The study included 200 patients on regular hemodialysis at Nephrology Department, University Medical Center Zvezdara. Retrospective analysis included a collection of general and vascular access data from medical records. Genetic analysis was performed by using polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFLP). Patients were divided into two groups: Group 1—patients who have never experienced vascular access failure and Group 2—patients who have at least one spontaneous vascular access failure. There was no difference in age, gender, hemodialysis vintage, main diagnosis, presence of hypertension, and diabetes mellitus between the two groups. There were no statist...
