原发性高血压合并冠心病患者脂蛋白(a)的变化

目的 探讨原发性高血压(EH)合并冠心病患者血清脂蛋白(a)[Lp(a)]水平的变化及其临床意义.方法 选择老年EH患者159例,根据冠状动脉造影结果分为单纯EH组73例和合并冠心病组86例,检测其空腹血糖、肌酐、总胆固醇、甘油三酯、LP(a)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C),计算体重指数.结果 与单纯EH组相比,Lp(a)水平在EH合并冠心病组明显增高[(0.34±0.12)、(0.48±0.18)mmol/L,t=-11.367,P＜0.05],在EH合并冠心病组中随冠状动脉病变程度的加重Lp(a)水平呈增高趋势[单支、双支、多支及弥漫病变组分别为(0.34±0.14)、(0.46±0.15)、(0.66±0.12)mmol/L,F=31.842,P=0.012].结论 EH患者Lp(a)水平与冠心病的发生及其严重程度相关.Lp(a)作为冠心病的危险因素,可以预测冠状动脉病变的严重程度.

Abstract：

Objective To study the changes of lipoprotein(a)[LP(a)] in patients with essential hypertension(EH) and coronary heart disease(CHD).Methods One hundred and fifty-nine EH older patients were recruited in the study.Eighty-six elderly patients were diagnosed as EH combined with CHD,and 73 patients were diagnosed as simple EH.All patients were tested for the fasting blood glucose(FBG),creatinine(Cr),total cholesterol(TC),triglyceride(TG),HDL-C,LDL-C,LP(a),and the body mass index(BMI) was calculated.Results Plasma Lp(a) increased(0.48±0.18)mmol/L in the EH combined with CHD patients,which were significantly higher than the increasing of(0.34±0.12) mmol/L in the simple EH patients(t=-11.367,P＜0.05).The level of plasma Lp(a) increased with the severity of the stenosis of the coronary artery(Lp(a):(0.37±0.14) mmol/L in single arterial branch stenoses,(0.46±0.15)mmol/L in double arterial branch stenoses,(0.66±0.12)mmol/L in triangle arterial branch stenoses,F=31.842,P=0.012).Conclusion The Lp(a) concentration in patients with EH are correlated with the occurrence and severity of coronary heart disease.As a risk of coronary heart disease,Lp(a) can predict the severity of coronary artery stenosis.
