Epidemiology of Acute Renal Failure and Related Factors after Coronary Artery Bypass Surgery in Mazandaran Heart Center

Abstract

Background and purpose: Acute kidney failure is one of the major problems around the world. It increases the rate of morbidity and mortality, and also leads to increased hospitalization time and health care costs. This study aimed at investigating the prevalence of acute kidney failure following coronary artery bypass grafting (CABG). Materials and methods: In a descriptive study, 400 medical records of CABG cases in Mazandaran Herat Center (2013-2016) were studied using random sampling. Creatinine levels of 24 hours before and after the surgery were recorded in a checklist. Data were analyzed in SPSS V20 applying Logistic Regression Analysis. Results: The patients studied included 59% males and 41% females. The mean age of patients was 61±9.05 years. The prevalence of acute renal failure was 13.5% following CABG. Based on univariate regression, gender (OR = 5.71, P < 0.0001), smoking (OR = 3.497, P = 0.006), BMI (OR =3.023, P =0.034), and BUN level (OR =3.026, P = 0.009) were found to be significantly associated with acute renal injury. Conclusion: In this study, age, sex, smoking, BUN levels and BMI were associated with the incidence of acute kidney failure after CABG.
