Abstract
Abstract Objectives Coronary artery disease (CAD) is a pathological condition resulting from atherosclerosis in the coronary arteries. IL17A has been shown to recruit and activate macrophages in atherosclerotic lesions, thereby participating in plaque destabilization. Currently, whether OLR1 and IL17A variants are involved in the pathogenesis of CAD is unclear. This case-control study aimed to investigate their roles in CAD etiology and prognosis. Methods In this study, 100 severe CAD patients who had undergone the coronary artery bypass graft surgery and 100 healthy controls were genotyped for OLR1 rs11053646, IL17A rs3819025, and rs8193037 variants via RT-PCR. Results The patients with OLR1 rs11053646 CG + GG genotype demonstrated a higher frequency of multi-vessel stenosis (18%) than single- (11.10%) or double-vessel (13.30%) stenosis (p=0.77). Additionally, although not statistically significant, this group of patients had 6.280 times more CAD risk than CC genotype carriers (p=0.089). Furthermore, logistic regression analysis revealed significant associations between the three variants and the risk factors for CAD development, namely waist circumference (p=0.002), body mass index (p=0.013), fasting glucose level (p=0.006), and triglyceride levels (p=0.035). Conclusions OLR1 rs11053646, IL17A rs3819025, and rs8193037 variants do not increase the risk for CAD development. However, this conclusion should be confirmed with a larger cohort.
