Carotid Ultrasound and Blood Serum Uric Acid in the Diagnosis of Coronary Heart Disease

【摘要】 目的 探讨血尿酸水平、颈动脉斑块与冠心病之间的关系。 方法 收集2006年1月-2009年12月拟诊为冠心病的住院患者280例,冠状动脉造影检查冠状动脉狭窄程度gt;50%的194例为冠心病组,冠状动脉无狭窄或狭窄程度lt;50%的86例为对照组;冠心病组又分为单支、双支、多支病变亚组。分别测定冠心病组与对照组颈总动脉与颈动脉分叉处内膜中层厚度(IMT)、等级评分、Crouse积分、血尿酸浓度。结果 与对照组相比,冠心病组颈总动脉与颈动脉分叉处IMT、等级评分、Crouse积分、血尿酸浓度均高于对照组,差异有统计学意义。在冠心病组,随病变分支的增多,颈动脉超声检查指标与血尿酸随之升高(Plt;0.05或0.01)。 结论 颈动脉IMT、等级评分、Crouse积分、血尿酸浓度与冠心病相关,是冠心病的独立危险因素。【Abstract】 Objective To investigate the relationships between serum uric acid levels, carotid artery plaque and coronary heart disease (CHD). Methods 194 patients with CHD and 86 nonCHD patients were selected through coronary angiography in patients with essential hypertension. CHD group was divided into three subgroups including a single branch, doublebranch and multivessel disease. Intimamedia thickness (IMT) of carotid artery and carotid bifurcation, grade score, Crouse score, serum uric acid concentrations were detected in patients with coronary heart disease and control group. Results IMT of carotid artery and carotid bifurcation, grade score,crouse score, serum uric acid concentrations were higher in CHD group than that in control group, and the difference was statistically significant. In the CHD group, ultrasound parameters of carotid artery and serum uric acid increased with the increase in branch lesions (Plt;005 or 001). Conclusions Carotid IMT, grade score, Crouse score, serum uric acid concentration relate to coronary heart disease, which is an independent risk factor for coronary heart disease, respectively.
