Brief Summary:
To evaluate the utility of plasma cystatin C(pCysC) as a predictive and diagnostic marker of acute kidney injury(AKI) in patients undergone cardiopulmonary bypass surgery.

Condition or disease
Acute Kidney Injury

Detailed Description:
This is a prospective AKI observational study in patients undergone cardiopulmonary bypass surgery. pCysC and plasma creatine will be measured at entry to ICU.AKI was defined as 50% increase in plasma creatine above baseline.The predictive and diagnostic performance of pCysC will be assessed from area under receiver operator characteristic curve(AUC) and odds ratio(OR).

Study Type : Observational
Estimated Enrollment : 100 participants
Observational Model: Case Control
Time Perspective: Prospective
Official Title: Use of Cystatin C in Predicting AKI in Patients Undergone Cardiopulmonary Bypass Surgery
Study Start Date : April 2011
Estimated Primary Completion Date : May 2013
Estimated Study Completion Date : May 2013

AKI group
patients with AKI after cardiopulmonary bypass surgery
non-AKI group
patients without AKI during study period
