Prediction and Prevention of Acute Kidney Injury after Cardiac Surgery

Abstract EN

The incidence of acute kidney injury after cardiac surgery (CS-AKI) ranges from 33% to 94% and is associated with a high incidence of morbidity and mortality.

The etiology is suggested to be multifactorial and related to almost all aspects of perioperative management.

Numerous studies have reported the risk factors and risk scores and novel biomarkers of AKI have been investigated to facilitate the subclinical diagnosis of AKI.

Based on the known independent risk factors, many preventive interventions to reduce the risk of CS-AKI have been tested.

However, any single preventive intervention did not show a definite and persistent benefit to reduce the incidence of CS-AKI.

Goal-directed therapy has been considered to be a preventive strategy with a substantial level of efficacy.

Many pharmacologic agents were tested for any benefit to treat or prevent CS-AKI but the results were conflicting and evidences are still lacking.

The present review will summarize the current updated evidences about the risk factors and preventive strategies for CS-AKI.
