Risk factors of cardiac surgery-associated acute kidney injury: development and validation of a perioperative predictive nomogram.

The novel predictive nomogram achieved a good preoperative prediction of CSA-AKI within the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Though the model, the risk of an individual patient with "subclinical AKI" undergoing cardiac surgery could be determined earlier and such application was helpful for timely intervention in order to improve patient's prognosis.
