Summary

The aim of this study was to apply the acute kidney injury criteria based on KDIGO classification in a population of patients undergoing cardiac surgery \[coronary artery bypass grafting (CABG) or cardiac valve surgery (CVS)\] and evaluate its impact as a predictor of 30-day mortality.

Detailed description

This was a single center study. We evaluated retrospectively patients from the Cardiac Surgery Intensive Care Unit in Hospital de Base, São José do Rio Preto Medical School, São Paulo, Brazil. Demographics, type of surgery, laboratory data and preoperative, perioperative, and postoperative information were retrieved from a prospectively collected database of 2878 patients older than 18 years undergoing isolated CABG (1786) or CVS (1092), from January 2003 to June 2013. After applying the exclusion criteria (51 patients with incomplete data and 23 patients with end-stage kidney disease) we analyzed 2804 patients in total, 1738 (62%) underwent CABG and 1066 (38%) underwent CVS.
