Acute Kidney Injury Following Cardiac Surgery

Completed

• Conditions: Acute Kidney Injury

• Registration Number: NCT03102528
• Lead Sponsor: University of Giessen

Brief Summary

Acute kidney injury (AKI) occurs in approximately one-third of patients undergoing cardiac surgery (CS), and represents one of the most significant negative predictors of patient outcome in this population. The investigators sought to examine the risk factors associated with the development of AKI and renal recovery in patients undergoing cardiac surgery at San Bortolo Hospital, Italy 2014-2015.

Detailed Description

Acute kidney injury (AKI) occurs in approximately one-third of patients undergoing cardiac surgery (CS), and represents one of the most significant negative predictors of patient outcome in this population. The investigators sought to examine the risk factors associated with the development of AKI and renal recoveryin patients undergoing cardiac surgery at San Bortolo Hospital, Italy during November 2014 - October 2015.
