血管紧张素转换酶基因多态性与冠心病危险因素的关系

目的 探讨血管紧张素转换酶（ＡＣＥ）基因多态性与冠心病危险因素的关系。方法 应用聚合酶链反应技术和遗传学方法，测定１５９名汉族正常人、１４８例冠心病患者的ＡＣＥ基因插入／缺失（Ｉ／Ｄ）多态性频率，并调查冠心病患者经内危险因素。结果①ＡＣＥ基因型分布与冠心病患者的年龄、性别、体重指数（ＢＭＩ）、收缩压、舒张压、总胆固醇（ＴＣ）、甘油三酯（ＴＧ）、低密度脂蛋白（ＬＤＬ）、高密度脂蛋白（ＨＤＬ）、ＨＤＬ

The relationship between angiotensin converting enzyme gene polymorphismand risk factors for coronary heart disease

OBJECTIVE: To explore the relationship between angiotensin converting enzyme (ACE) gene polymorphism and risk factors for coronary heart disease (CHD). METHODS: 148 patients with CHD and 159 unrelated healthy individuals were studied using polymerase chain reaction (PCR) and genetic methods. Risk factors of CHD were assessed by standard questionnaire, physical examination and blood tests. RESULTS: (1) There were no significant differences among genotypes in terms of years, sex, body mass index (BMI), systolic blood pressure, diastolic blood pressure, total cholesterol (TC), triglyceride (TG), low-density lipoprotein-cholesterol (LDL), high-density lipoprotein-cholesterol (HDL), HDL(2), HDL(3), apolipoprotein (Apo) AI, ApoB, and lipoprotein (a) [Lp (a)]. The prevalence rates of hyperlipidemia, hypertension (HT), cigarette smoking, diabetes mellitus (DM) and obesity were similar in the ACE genotypes (P > 0.05). (2) The DD genotype frequencies in low CHD risk groups, as defined by ApoB < 125 mg/dl and BMI
