Background: Angiopoietin-2 (Angpt2) is associated with the progression of coronary artery disease (CAD). This research aimed to investigate the possible association between single nucleotide polymorphisms (SNPs) of ANGPT2 and CAD.
Methods: This research was performed in a hospital from the eastern region of China. From February 2019 to June 2019, 222 patients with CAD were newly diagnosed and 403 healthy controls were confirmed by physical examinations. The distribution frequency of five SNPs of the ANGPT2 (rs11137037, rs2442598, rs12674822, rs1823375, and rs734701) in all participants was analyzed by real-time polymerase chain reaction (PCR) with SNP locus-specific probes.
Results: Our data showed that the participants with the TT genotype of rs2442598 were at reduced risk of CAD compared with wild-types (adjusted odds ratio [AOR] = 0.511, 95% CI: 0.283-0.923). The participants with the AC and AC+CC genotypes of rs11137037 were at greater risk of CAD compared to wild-types (AOR = 1.754, 95% CI: 1.140-2.699; AOR = 1.731, 95% CI: 1.165-2.573, respectively). In addition, carriers of the GG+TT genotypes of rs12674822, showed more significant high-density lipoprotein than those of GG genotype, in addition, carriers of the GG+TT genotypes of rs12674822, showed more significant high-density lipoprotein than those of GG genotype (P=0.037).
Conclusion: These findings, as well as analysis of the haplotype, clearly indicate that ANGPT2 SNPs were highly correlated with susceptibility to CAD among the Han Chinese population.
