目的:基于多因子降维法(GMDR)分析亚甲基四氢叶酸还原酶(MTHFR)C677T 基因多态性-Hcy交互作用对高血压合并冠心病的影响。方法:选取 2021 年 3 月至 2022 年 10 月我院收治的150 例高血压患者作为研究对象,根据冠脉造影结果分为单纯高血压组(n=51)、高血压合并冠心病组(n=99),比较两组一般资料、Hcy水平、MTHFR C677T 基因多态性分布,采用 Logistic 回归方程分析高血压合并冠心病影响因素,采用 GMDR 分析 MTHFR C677T 基因多态性与 Hcy 交互作用。结果:两组MTHFR C677T基因型频率实测值与理论值比较差异无统计学意义(P>0。05);高血压病程、Hcy、LDL-C、MTHFR C677T基因型-TT及等位基因T是高血压合并冠心病影响因素(P<0。05);GMDR结果显示,MTHFR C677T基因型-TT与Hcy交互模型为高血压合并冠心病风险的最优模型,其交叉检验一致性为10/10,检验准确度为 75。00%,符合检验值为 0。011。结论:MTHFR C677T 基因多态性、Hcy 交互作用可能增加冠心病发生风险,临床应动态监测上述指标变化情况,及时采取有效治疗措施,减少冠心病发生。
Analysis of the Impact of MTHFR C677T Gene Polymorphism-Hcy Interaction on Hypertension Complicated with Coronary Heart Disease Using Multifactor Dimensionality Reduction
Objective:To analyze the effect of methylene tetrahydrofolate reductase(MTHFR)C677T gene polymorphism-Hcy interaction on hypertension combined with coronary heart disease based on multifactor dimension reduction(GMDR).Methods:A total of 150 hypertensive patients admitted to our hospital from March 2021 to October 2022 were selected as the study subjects.Based on coronary angiography results,they were divided into the isolated hypertension group(n= 51)and the hypertension complicated with coronary heart disease group(n=99).General information,Hcy levels,and MTHFR C677T gene polymorphism distri-bution were compared between the two groups.Logistic regression analysis was used to identify factors influen-cing hypertension complicated with coronary heart disease,and GMDR was employed to analyze the interaction between MTHFR C677T gene polymorphism and Hcy.Results:There was no statistically significant difference between the observed and theoretical values of MTHFR C677T genotypic frequencies in the two groups(P>0.05).The duration of hypertension,Hcy,LDL-C,MTHFR C677T genotypes(TT),and the T allele were i-dentified as influencing factors for hypertension complicated with coronary heart disease(P<0.05).GMDR results showed that the TT genotype of MTHFR C677T in interaction with Hcy formed the optimal model for the risk of hypertension complicated with coronary heart disease.The cross-validation consistency was 10/10,the testing accuracy was 75.00%,and the sign test P-value was 0.011.Conclusion:MTHFR C677T gene poly-morphism and the interaction with Hcy may increase the risk of coronary heart disease.Clinicians should dy-namically monitor changes in these indicators and take effective treatment measures promptly to reduce the oc-currence of coronary heart disease.
