Abstract

Background: Acute kidney injury (AKI) is a complex syndrome defined as rapid decrease in glomerular filtration rate and therefore, retention of metabolic waste substances. The risk of AKI in candidates for coronary artery bypass graft (CABG) surgery usually is highlighted. The main objective of this study was to determine the AKI prevalence after CABG surgery.Methods: This observational study was performed on 1534 patients undergoing CABG surgery in Sina cardiac surgery center, Isfahan, Iran during 2006 till 2010. The information of patients was collected from hospital data sheet and recorded in a questionnaire. AKI was determined by laboratory data.Findings: 76.4% of the patients were men. The patients were 60.8 ± 8.9 years old with the average body mass index (BMI) of 27.0 ± 4.3 kg/m2. The prevalence of AKI was 49.1%. In overall, the hospital mortality rate was 2.7% and 0.7% of patients were assigned for dialysis.Conclusion: Our results indicated that the prevalence of AKI was considerably high. Special attention and hospital take cares are needed to reduce this prevalence.
