Determinant factors of renal failure after coronary artery bypass grafting with on-pump technique.

Objective: The aim of the present study was to investigate the determinant factors of acute renal failure (ARF) after isolated on-pump coronary artery bypass grafting (CABG).

Subjects And Methods: This was a retrospective study of 13,315 adult patients who underwent isolated CABG with cardiopulmonary bypass (CPB) in Tehran Heart Center from May 2002 to May 2007. The exclusion criteria were age <18, concomitant cardiac and/or noncardiac surgical operations, history of renal failure before surgery, and chronic renal failure requiring dialysis.
