PurposeStatins, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors have the potential to reduce acute kidney injury (AKI) after cardiac surgery through their pleiotropic properties. Here we studied the preventive effect of atorvastatin on AKI after valvular heart surgery.MethodsTwo-hundred statin-naïve patients were randomly allocated to receive either statin or placebo. Atorvastatin was administered orally to the statin group according to a dosage schedule (80 mg single dose on the evening prior to surgery; 40 mg on the morning of surgery; three further doses of 40 mg on the evenings of postoperative days 0, 1, and 2). AKI incidence was assessed during the first 48 postoperative hours on the basis of Acute Kidney Injury Network criteria.ResultsThe incidence of AKI was similar in the statin and control groups (21 vs. 26 %, respectively, p = 0.404). Biomarkers of renal injury including plasma neutrophil gelatinase-associated lipocalin and interleukin-18 were also similar between the groups. The statin group required significantly less norepinephrine and vasopressin during surgery, and fewer patients in the statin group required vasopressin. There were no significant differences in postoperative outcomes.ConclusionsAcute perioperative statin treatment was not associated with a lower incidence of AKI or improved clinical outcome in patients undergoing valvular heart surgery.
