Evaluation of the incidence of acute kidney injury following coronary artery bypass graft surgery

Introduction: Coronary artery bypass grafting (CABG) is one of the most common surgical methods in patients with coronary artery disease, a well-known complication of which is renal injury after surgery. Here we try to understand the factors involved in the incidence of acute renal injury in our patients.Objective: The aim of this study was to evaluate the incidence and etiology of acute kidney injury (AKI) following CABG.Methods: This study was performed on ۱۸۱ patients undergoing CABG surgery. AKI was also recorded after registering demographic information and clinical indications. Chi-square, Mann-Whitney and independent t-tests were used for data comparison.Results: The findings of our study showed that AKI following CABG in our patients was ۳.۹% which had no significant relationship with age, sex, hypertension, diabetes, type of surgery, hypercholesterolemia, number of clogged arteries, smoking and length of surgery; however,blood, urea was found to be significantly higher preoperatively in patients with AKI. Conclusion: The results of our study revealed that AKI following CABG in the studied patients was ۳.۹%, which was not significantly related to age, sex, hypertension, diabetes, type of surgery, hypercholesterolemia, number of clogged vessels, smoking and the length of surgery. although, the urea was observed to be significantly higher in patients with AKI before surgery. Studies with larger sample sizes are recommended.
