Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

People who undergo coronary artery bypass grafting (CABG) or heart valve surgery may experience acute kidney injury (AKI) after their surgery. Current medical tests cannot identify AKI until approximately 48 hours after it occurs. This study will examine three new biomarkers in blood and urine that may provide a more effective and faster way of predicting AKI in people who undergo CABG or heart valve surgery.
