摘 要: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。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 ) mmot/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.
