摘　　要：目的 探讨血清脂蛋白水平与冠心病患者冠状动脉病变的关系.方法 冠状动脉造影患者323例,分为冠心病组和正常对照组,其中根据冠状动脉病变狭窄程度分为轻度、中度、重度狭窄组,根据冠状动脉病变范围分为单支病变组、双支病变组和多支病变组.分别测定其血清脂蛋白、总胆固醇、低密度脂蛋白、甘油三酯水平.结果 冠心病组血清脂蛋白、总胆固醇、低密度脂蛋白、甘油三酯水平明显高于正常对照组.其中血清脂蛋白、总胆固醇和低密度脂蛋白水平与冠状动脉病变呈正相关;双支及多支病变组明显高于对照组和单支病变组(P<0.01),中度狭窄和重度狭窄组明显高于对照组和轻度病变组(P<0.01).结论 血清脂蛋白、总胆固醇和低密度脂蛋白能够反映冠状动脉的病变情况,其水平随冠状动脉病变范围及病变程度的加重而升高,可作为预测冠状动脉病变的一个因素.Objective To investigate the possible relationship between the serum LP(a) and coronary artery changes in patients with coronary heart disease (CHD). Methods Coronary angiography (CAG) was performed in 323 patients. The patients were divided into CHD group and control group. The serum levels of lipids were measured. According to the coronary number of stenosis, CHD group was further divided into 1-vessel group, 2-vessel group and 3-vessel group according to the degree of coronary lesion, CHD group was further divided into light stenosis group, moderate stenosis group and severe stenosis group. Results The levels of total cholesterol (TC),LP(a),LDL-C and triglyceride (TG) in CHD patients were significant higher than those in the control group. The serum levels of TC,LP(a) and LDL-C were significantly related to CHD (P<0.01).The serum levels of TC,LP(a) and LDL-C were higher in the 2-vessel group and 3-vessel group than that in the control group and 1-vessel group (P<0.01).The serum levels of TC,LP(a) and LDL-C were higher in the moderate stenosis group, severe stenosis group than that in the control group and light stenosis group(P<0.01). Conclusions The increasing of TC, LP(a) and LDL-C are associated with the stenosis degrees and lesion degrees of coronary artery in patients with CHD which indicated that TC,LP(a) and LDL-C have clinical significance for evaluating the change of degree of coronary artery lesion.
