Abstract: Objective To investigate the relationship between preoperative albumin level and postoperative acute kidney injury(AKI)following off-pump coronary artery bypass(OPCAB)surgery;to confirm albumin cut-off value associated with AKI. Method This was a retrospective cohort study. data from patients who accepted OPCAB surgery in last two years in our hospital and AKI was diagnosed according to KIDGO-AKI criteria. Results Generalized additive model and multivariable logistic regression analysis have shown that the higher preoperative albumin level is related with the lower the incidence of AKI after OPCAB surgery. By generalized additive model,multivariable logistic regression analysis and ROC curve,we confirmed the albumin cut-off value associated with AKI between 39~40 g/L. Conclusion For patients undergoing OPCAB surgery,the higher preoperative albumin level ,the lower the incidence of AKI. In order to reduce the incidence of AKI in OPCAB surgery patients,preoperative albumin level higher than 40 g/L should be maintained.
