血清尿酸含量与冠心病的相关性研究

目的：研究血清尿酸（SUA）含量与冠状动脉病变程度的关系。方法：选择2006年10月~2008年10月在我科住院并行冠状动脉造影的患者205例。根据冠状动脉造影结果分为CHD组154例和非CHD组51例,比较两组间有关指标的差别。根据SUA水平CHD组又被分为高尿酸组（96例）和正常尿酸组（58例）两个亚组,分析SUA水平与冠脉病变程度的关系。根据CHD病变血管支数分为单支、双支、多支病变三个亚组,比较三亚组间SUA水平。结果：（1）CHD组患者的SUA水平明显高于非CHD组（486.94±162.96）μmol/L∶（305.69±99.58）μmol/L,P〈0.05];（2）高尿酸血症的检出率为54.1%,其中CHD组的尿酸异常率为62.34%（96/154）,明显高于非CHD组的尿酸异常率29.41%（15/51）,P〈0.05];（3）SUA水平与性别有关,与收缩压、甘油三酯（TG）呈正相关,与高密度脂蛋白（HDL）呈负相关,r分别为0.339,0.244,0.156,-0.102,P〈0.05;（4）单支、双支、多支病变三个亚组的SUA水平分别为（387.07±100.14）μmol/L,（474.43±133.62）μmol/L,（581.30±180.21）μmol/L。SUA水平随着冠脉病变血管支数的增加而明显升高,P均〈0.01。三亚组的冠脉狭窄积分分别为（6.93±4.48）分,（16.54±11.13）分,（33.67±17.85）分,两两比较有显著差异（P均〈0.01）;（5）Logistic回归分析显示,年龄、SUA、低HDL为CHD的危险因素,OR值分别为1.102,1.012,0.397。结论：（1）血尿酸水平与性别有关,与收缩压和甘油三酯呈正相关,与高密度脂蛋白呈负相关;（2）血尿酸水平随着冠状动脉病变程度的加重而逐渐增加,是反映冠心病严重程度的一种重要生化指标;（3）在冠心病的防治中,除控制传统危险因素外,对高尿酸血症也不容忽视。

Relationship between serum concentration of uric acid and coronary heart disease

Objective:To study the relationship between level of serum uric acid(SUA) and coronary artery disease.Methods:A total of 205 cases received coronary angiography and hospitalized in our department from October 2006 to October 2008 were collected.According to the results of coronary angiography,the patients were divided into CHD group(n=154) and non-CHD group(n=51) and correlated indexes were compared between the two groups.According to level of SUA,CHD group was divided into two subgroups: high SUA group(n=9...
