尿微量蛋白和 BNP 联合诊断心肾综合征的意义

Diagnostic Significance of Microalbuminuria Combined BNP for Cardiorenal Syndrome

目的：探讨尿微量蛋白和脑钠肽（BNP）联合诊断心肾综合征的意义。方法2011年8月-2014年2月选择在北京市西城区展览路医院住院诊治的心肾综合征患者45例作为观察组，选择同期在该院进行体检的健康人45例作为对照组，两组都进行了超声检查与尿液、血液学指标检测，同时对临床资料进行调查。结果观察组的主动脉根部内径、左房内径和室间隔厚度都明显高于对照组（P ＜0.05），而两组的右室内径与左心室射血分数对比差异无统计学意义。观察组的尿素氮、肌酐、脑钠肽与尿微量蛋白含量都明显高于对照组（P ＜0.05）。logistic 多元回归分析显示导致心肾综合征发生的主要独立危险因素包括脑钠肽、尿微量蛋白、主动脉根部内径与尿素氮等（P ＜0.05）。结论尿微量蛋白和 BNP 联合诊断心肾综合征有很好的诊断价值，能有效判断疾病状况，也是心肾综合征发生的独立危险因素。

Objective To investigate the diagnostic significance of microalbuminuria combined BNP for cardiorenal syndrome. Methods Selected 45 patients with cardiorenal syndrome from August 2011 to February 2014 in the Exhibition Road, Xicheng District hospital in Beijing as the observation group,choose the 45 cases of healthy people at same period in the Ex-hibition Road,Xicheng District hospital in Beijing as the control group,two groups were carried out ultrasound and urine,he-matological tested,while the clinical data were investigated.Results The aortic root diameter,left atrial diameter and septal thickness of the observation group were significantly higher （P 〈0.05）,while the right ventricular diameter and left ventric-ular ejection fraction compared in the two groups were no significant difference.The urea nitrogen,creatinine,brain natri-uretic peptide and microalbuminuria contents in the observation group were significantly higher （P 〈0.05）.Multivariate lo-gistic regression analysis showed that the main independent risk factors for cardiorenal syndrome included brain natriuretic peptide,microalbuminuria,aortic root diameter and blood urea nitrogen （P 〈0.05）.Conclusion The diagnosis of microalbu-minuria combined BNP for cardiorenal syndrome has better diagnostic value that can effectively determine the disease status, and there were independent risk factors for cardiorenal syndrome.
