根据发表在美国肾脏病学会杂志(JASN)最新一期的一项研究,尿液中蛋白质的水平可以帮助医生预测哪些急性心脏衰竭患者在住院期间有发展为肾损伤的风险。

在全球范围内急性心脏衰竭导致住院的首要原因。在急性失代偿性心脏衰竭(ADHF)患者中,会在患者以前的或现有的心脏问题症状加重时发生,由于心脏和肾脏之间的连接25%至51%发展为急性肾损伤(AKI)。不幸的是,没有可靠的临床标志物,来帮助临床医生预测哪些患者会有发展为AKI的高风险。

医学博士Xiaobing Yang和Fan Fan Hou(南方医科大学,广州,中国)和他们的同事进行了436例ADHF患者一项研究,验证新的标记,尿血管紧张素原(uAGT),用于预测患者发展为AKI的风险。uAGT在调节血压和肾健康中起重要作用。

该研究小组证明,入院时uAGT水平预测AKI风险具有相当的准确性。与最低四分位数相比,入院时uAGT最高四分位数与增加AKI的50倍风险有关系。患者在入院时uAGT水平也帮助医生预测患者再入院治疗或一年内的风险。

Hou博士说:“我们的结果提高了通过使用敏感和特异性标志物如uAGT的可能性,临床医生可以确定ADHF患者在入院第一天时尽早发现其发展为AKI的风险。如果得到证实,入院第一天的uAGT水平就可以提高临床医生评估ADHF患者发展为AKI的风险的能力,并预测其1年的预后,这反过来将帮助临床医师为患者在住院期间和出院后规划和启动最合适的管理策略。”
