摘要:

目的 研究PON1-Q192R基因多态性与冠心病患者冠状动脉病变严重程度的关联性,并分析冠状动脉狭窄程度的影响因素。 方法 纳入2024年1—12月在江苏省苏北人民医院明确诊断为冠心病的患者为研究对象,采用PCR-焦磷酸测序法检测患者PON1-Q192R基因型。比较不同基因型患者基线资料,根据Gensini评分系统将患者冠状动脉病变严重程度分为轻度狭窄组(< 20分)、中度狭窄组(20 ~ 39分)、重度狭窄组(≥ 40分),观察PON1-Q192R基因多态性与Gensini评分的相关性,比较不同基因型在冠心病患者中冠状动脉狭窄分组间的分布特点。采用单因素和多因素logistic回归分析,探究冠状动脉狭窄程度的相关影响因素。 结果 Gensini评分中位值显示,AG、AA基因型显著高于GG基因型患者(P<0.05); AG&AA基因型重度狭窄患者比例显著高于GG基因型(P < 0.05);PON1-Q192R等位基因G/A在不同冠状动脉狭窄程度间的分布比较差异有统计学意义(P < 0.05)。多因素logistic回归分析结果显示,AG基因型(OR = 1.973,95%CI:1.078~3.610,P = 0.027)、AA基因型(OR = 3.127,95%CI:1.245~7.853,P = 0.015)、高血压(OR = 2.234,95%CI:1.233~4.046,P=0.008)、糖尿病(OR = 2.043,95%CI:1.064~3.920,P = 0.032)、LDL-C升高(OR = 1.608,95%CI:1.157~2.234,P = 0.005)是冠状动脉狭窄程度加重的危险因素。 结论 PON1-Q192R基因多态性与冠心病患者冠状动脉狭窄程度风险升高显著相关。PON1-Q192R基因多态性可作为预测冠心病患者冠状动脉狭窄程度的重要指标。

Abstract:

Objective To evaluate the association between the PON1-Q192R gene polymorphism and the severity of atherosclerotic lesions in coronary arteries among patients with coronary heart disease,and to analyze the influencing factors of the degree of coronary artery stenosis. Methods Patients diagnosed with coronary heart disease at Northern Jiangsu People's Hospital between January 2024 and December 2024 were enrolled in this study. The PON1-Q192R genotype was detected using PCR-based pyrosequencing. Compare the baseline data of patients with distinct genotypes. Patients were categorized into groups based on the severity of coronary atherosclerosis according to the Gensini score system:mild stenosis group(< 20 points),moderate stenosis group(20 - 39 points),and severe stenosis group(≥ 40 points).The study examined the correlation between the PON1-Q192R gene polymorphism and Gensini scores,and compared the distribution characteristics of different genotypes across coronary artery stenosis groups in patients with coronary heart disease. Univariate and multivariate logistic regression analyses were employed to investigate the associated factors influencing the degree of coronary artery stenosis. Results The median Gensini score showed that patients with the AG and AA genotypes were significantly higher than those with the GG genotype(P < 0.05).The proportion of patients with severe stenosis in the AG and AA genotypes was significantly higher than that in the GG genotype(P < 0.05).Comparing the distribution of the PON1-Q192R G/A alleles across different degrees of coronary artery stenosis also showed statistically significant differences(P < 0.05).Multivariate logistic regression analysis revealed that the AG genotype(OR = 1.973,95%CI:1.078 - 3.610,P = 0.027),AA genotype(OR = 3.127,95%CI:1.245 - 7.853,P = 0.015),hypertension(OR = 2.234,95%CI:1.233-4.046,P = 0.008),diabetes mellitus (OR = 2.043,95%CI:1.064 - 3.920,P = 0.032),and elevated LDL-C(OR = 1.608,95%CI:1.157 - 2.234,P = 0.005)were identified as risk factors for increased coronary artery stenosis severity. Conclusions The PON1-Q192R gene polymorphism is significantly associated with an increased risk of coronary artery stenosis severity in patients with coronary heart disease. The PON1-Q192R gene polymorphism can serve as an important indicator for predicting the severity of coronary artery stenosis in patients with coronary heart disease.
