Study design:

Cohort study 

研究目的:

明确肾阻力指数(RRI)与术后血清胱抑素 C(CysC)单独及联合应用时,对心脏手术相关急性肾损伤(CSA-AKI)的预测效能,计算各指标及联合指标的受试者工作特征曲线下面积(AUC)、灵敏度、特异度、阳性预测值与阴性预测值,确定最佳预测阈值。  

Objectives of Study:

To clarify the predictive efficacy of renal resistive index (RRI) and postoperative serum cystatin C (CysC) when used alone and in combination for cardiac surgery-associated acute kidney injury (CSA-AKI), calculate the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, positive predictive value, and negative predictive value for each individual index and the combined index, and determine the optimal predictive threshold.
