摘　　要：目的:探讨血浆同型半胱氨酸(Hcy)与冠心病相关性及与冠心病传统危险因素的关系研究。方法:120例行冠状动脉造影的患者,根据冠状动脉造影结果分为冠心病组(至少1支冠状动脉狭窄≥50%,n=70)及对照组(冠状动脉造影正常,n=50),测定两组血浆Hcy水平、血脂、射血分数等,以Gensini评分评价冠状动脉病变程度,应用Pearson单因素分析Hcy与冠心病患者血脂、心功能及冠状动脉病变程度的关系,应用Logistic多因素分析冠心病发生的危险因素。结果:冠心病患者体质量指数(BMI)、吸烟比例、高血压比例、血浆Hcy、低密度脂蛋白(LDL-C)均高于对照组(P<0.05),高密度脂蛋白(HDL-C)水平和左心室射血分数(LVEF)低于对照组(P<0.05);经Pearson单因素分析Hcy与冠脉病变Gensini评分和LDL-C呈正相关,与HDL-C、LVEF呈负相关(P<0.05);经Logistic多因素分析显示,高血压史、Hcy以及LDL-C是影响冠心病的独立危险因素,而HDL-C则是冠心病的保护因素。结论:Hcy与冠状动脉病变程度呈正相关,Hcy与高血压史及LDL-C水平都是冠心病的独立危险因素。Objective：To investigate correlation between homocysteine（ HCY）and coronary heart disease and traditional risk factors of coronary heart disease. Methods：120 cases of patients with rou-tine coronary angiography,coronary heart disease by coronary angiography were divided into coronary heart disease group（ at least one coronary artery stenosis ≥50%,n=70 ）and control group（ normal coronary arteries,n =50 ）;testing plasma HCY levels,blood lipids,heart function level of both groups,evaluating severity of coronary artery disease by Gensini,applying of Pearson univariate analy-sis to analyze the relationship between HCY and coronary heart disease blood lipids,cardiac function and severity of coronary artery disease,applying Logistic multivariate analysis of risk factors for coro-nary heart disease. Results：Coronary heart disease patients′body weight（ BMI）,the proportion of smoking history,history of hypertension,plasma HCY,low-density lipoprotein（ LDL-C）were higher than control group（ P〈0 . 05 ）,high density lipoprotein（ HDL-C ）,proportion of left ventricular ejec-tion fraction（LVEF）were lower than control group（P 〈0. 05）. Single factor analysis by pearson showed that Hcy were positively correlated with coronary pathological Gensini score and LDL-C and negatively correlated with HDL-C and LVEF. After Logistic multivariate analysis,history of hyperten-sion,HCY,HDL-C level was an independent risk factor for coronary heart disease,while HDL-C is the independent risk factor to influence coronary disease. Conclusion：history of hypertension,HCY, LDL-C in patients with coronary heart disease and severity of coronary artery disease are closely related are independent risk factors for coronary heart disease.
