Abstract:Objective To investigate the relationship between single nucleotide polymorphism of TET2 gene (rs2454206, rs12498609) and susceptibility to acute myocardial infarction.Methods We prospectively selected 150 patients with acute myocardial infarction admitted to our hospital as the case group from January 2022 to December 2022, and 150 healthy people admitted for physical examination in the same period as the control group. We compared the general data and blood lipid related indicators between the two groups, and determined the genotypes of rs2454206 and rs12498609 of TET2 gene by polymerase chain reaction (PCR). Logistic regression analysis was used to analyze the risk factors of acute myocardial infarction.Results There were significant differences in genotype frequency and allele frequency at rs2454206 and rs12498609 of TET2 gene between the two groups (P < 0.05). The results of univariate and multivariate logistic regression showed that Hypertension [O^R = 2.022 (95% CI: 1.202, 3.401) ], TC [O^R = 3.045 (95% CI: 2.146, 4.320) ], TG [O^R = 4.052 (95% CI: 2.405, 6.826) ], LDL-C [O^R = 3.022 (95% CI: 1.889, 4.834) ] level, TET2 gene rs2454206 locus AA genotype [O^R = 4.697 (95% CI: 2.675, 8.249) ], rs12498609 locus CC genotype [O^R = 2.147 (95% CI: 1.215, 3.795) ] were risk factors affecting the occurrence of acute myocardial infarction (P < 0.05), HDL-C level [O^R = 0.057 (95% CI: 0.015, 0.216) ] was a protective factor affecting the occurrence of acute myocardial infarction (P < 0.05).Conclusion The occurrence of acute myocardial infarction is affected by many factors. The AA genotype at rs2454206 and CC genotype at rs12498609 of TET2 gene may be related to the increased susceptibility to acute myocardial infarction.
