血尿酸水平与冠状动脉病变及代谢综合征的关系

目的 探讨血尿酸水平变化与冠状动脉病变程度、代谢综合征及其相关组分的关系.方法 343例(男性223例,女性120例)接受冠状动脉造影检查的患者,应用冠脉狭窄指数(CSI)评价冠状动脉病变严重程度.结果 (1)女性血尿酸水平显著低于男性[(306.3±76.9对358.9±85.2)μmol/L,P＜0.01],而男女性代谢综合征及各组分的患病率未见明显差异.(2)女性≥3项代谢异常亚组血清尿酸水平显著高于1项代谢异常亚组(P＜0.01)及2项代谢异常亚组(P＜0.05),而男性尿酸水平与代谢异常数目无明显关系.(3)将男、女人群的尿酸值分为4分位数,女性位于上1/4位点者的CSI评分高于下1/4位点者[7.0(2.5～12.0)对2.0(0.0～6.0),P=0.025].女性多支病变组血尿酸水平明显高于无病变组[(327.0±81.9对284.9±78.6)μmol/L,P=0.033].(4)Logistic回归显示年龄(β=0.042,P=0.007)和血脂异常(β=0.836,P=0.037)为男性冠脉病变的独立危险因素,而女性人群中血压异常(β=1.127,P=0.039)及血脂异常(β=0.901,P=0.009)为影响冠脉病变的主要因素.结论 血尿酸水平较高的女性,代谢异常组分聚集较多,其冠状动脉病变程度较重,故尿酸水平可作为女性动脉粥样硬化的标志.

Abstract：

Objective To analyze the association of blood uric acid level with the severity of coronary artery stenotic changes, metabolic syndrome (MS), and its components. Methods A total of 343 individuals ( male 223,female 120) who underwent coronary angiography and had complete data on MS and serum uric acid were collected. The severity of coronary artery disease (CAD) was assessed by the coronary stenesis index (CSI). MS was diagnosed according to the Guideline on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults. Results (1)The mean uric acid level was significantly lower in women than in men [ ( 306.3±76.9 vs 358.9±85.2 ) μmol/L, P＜0.01 ]. The prevalence of MS and its components showed no difference between men and women. (2) The uric acid level in women with 3 components was higher than those with1( P＜0. 01 ) or 2 ( P＜0.05 ) components of metabolic disorders, but not in men. (3) Quartiles of concentration of uric acid were computed. Compared with those in the lowest quartile of uric acid, women in the highest quartile had higher CSI score [ 7.0 (2.5-12.0) vs 2. 0( 0.0-6.0), P= 0. 025 ]. Moreover, the uric acid level was higher in women with multivessel lesions than nonCAD patients [ (327.0±81.9 vs 284.9±78.6) μmol/L, P = 0.033 ]. However, no correlation was found between uric acid level and the severity of coronary artery lesion in men. (4) Logistic regression showed that age (β=0.042, P=0. 007) and dyslipidemia(β=0.836, P=0. 037 ) were the independent risk factors of CAD in men, and hypertension(β=1. 127, P=0.039) and dyslipidemia(β=0.901, P=0.009)in women. Conclusions In women with higher uric acid level, the clustering of metabolic abnormalities was increased, and the coronary artery lesion was more severe. High uric acid level might be a marker of CAD for women.
