Abstract

Background: Cardiovascular diseases (CVDs) are the most common and the first cause of death worldwide. While some studies have investigated the association of the Adenosine Deaminase (ADA) gene with CDVs, its roles on in-stent restenosis (ISR) has not been studied. Methods and results: In this study, we investigated the role of ADA gene variants in both genetic and haplotype models on the risk of ISR. 91 samples were included in this study. The subjects were divided into two groups regarding having or not-having ISR (n = 40 ISR+ and n = 51 ISR−). The genotyping for G22A (rs73598374) and A4223C (rs452159) polymorphisms was performed using PCR–RFLP method. Statistical analysis was performed by SPSS v. 20 and Haploview 4.2 softwares. The basic demographic conditions in ISR groups were statistically similar. There was a significant association between A allele of rs452159 ISR groups after adjustment (allelic model: P value = 0.028, OR(95%CI) = 0.366(0.149–0.899)), while rs73598374 polymorphism shows no significant association with ISR. In haplotype analysis, the GA (G:rs73598374/A:rs452159) haplotype decreased the risk of ISR (P value = 00.025, OR(95%CI) = 0.382(0.161–0.907)). Conclusions: This study suggests that A allele of ADA rs452159 polymorphism and GA (G:rs73598374/A:rs452159) haplotype may be related to decreased risk of ISR in CAD patients receiving drug-eluting stent and offers more observational studies on ADA variants in other populations to generate a potential haplotype panel for ISR risk assessment. © 2021, The Author(s), under exclusive licence to Springer Nature B.V.
