Abstract
Abstract only Acute kidney injury (AKI) after endovascular aortic repair (EVAR) occurs in 20% of patients and is an independent predictor of death. Higher preoperative high-density lipoprotein (HDL) cholesterol concentration before revascularization of chronic limb ischemia is associated with a lower risk of AKI. Further, preoperative statin use has been shown to be associated with a decreased risk of AKI after EVAR. We hypothesized that both preoperative statin use and higher preoperative HDL are associated with a lower risk of AKI in patients undergoing EVAR. Charts from adult patients that underwent EVAR were selected using the ICD codes (n=251). Each chart was reviewed for demographic and medical information, preoperative and postoperative serum creatinine concentrations, and preoperative HDL concentration. One hundred and three patients had available statin medication, serum creatinine, and HDL concentrations. The associations between statin dose, HDL concentration and maximum serum creatinine change from baseline in the first 48 postoperative hours was assessed using multivariable linear regression models, adjusted for AKI risk factors. Preoperative HDL concentration was not correlated with preoperative statin dose (Pearson’s R=0.0515, p=0.57). Higher preoperative statin doses (atorvastatin equivalents) and higher preoperative HDL concentrations were associated with lower serum creatinine rise (p=0.042 and 0.002 respectively, Figure). When both preoperative statin dose and preoperative HDL concentration were included in the model, both variables lost significance, suggesting HDL may mediate the relationship between preoperative statin dose and postoperative AKI. Higher preoperative HDL concentrations and statin doses were associated with less postoperative AKI. Future work involves identifying the biological mechanism underlying these associations as a first step towards developing new therapies to prevent AKI following EVAR.
