Preprocedural statin administration may reduce contrast-induced acute kidney injury (CI-AKI), but current evidence is controversial. Randomized controlled trials (RCTs) comparing preprocedural statin administration before coronary catheterization with standard strategies were searched in MEDLINE/PubMed, EMBASE, Scopus, Cochrane Library, Web of Science, and Science Direct databases. The outcome of interest was the incidence of postprocedural CI-AKI. Prespecified subgroup analyses were performed according to baseline glomerular filtration rate (GFR), statin type, and N-acetylcysteine use. Eight RCTs were included for a total of 4,984 patients. The incidence of CI-AKI was 3.91% in the statin group (n = 2,480) and 6.98% in the control group (n = 2,504). In the pooled analysis using a random-effects model, patients receiving statins had 46% lower relative risk (RR) of CI-AKI compared with the control group (RR 0.54, 95% confidence interval [CI] 0.38 to 0.78, p = 001). A moderate degree of non-significant heterogeneity was present (I-2 = 41.9%, chisquare = 12.500, p = 0.099, tau(2) = 0.100). In the subanalysis based on GFR, the pooled RR indicated a persistent benefit with statins in patients with GFR <60 ml/min (RR 0.67, 95% CI 0.45 to 1.00, p = 0.050) and a highly significant benefit in patients with GFR 60 ml/min (RR 0.40, 95% CI 0.27 to 0.61, p <0.0001). Stalin type and N-acetylcysteine or hydration did not significantly influence the results. In conclusion, preprocedural statin use leads to a significant reduction in the pooled RR of CI-AKI

Abstract
Preprocedural statin administration may reduce contrast-induced acute kidney injury (CI-AKI), but current evidence is controversial. Randomized controlled trials (RCTs) comparing preprocedural statin administration before coronary catheterization with standard strategies were searched in MEDLINE/PubMed, EMBASE, Scopus, Cochrane Library, Web of Science, and Science Direct databases. The outcome of interest was the incidence of postprocedural CI-AKI. Prespecified subgroup analyses were performed according to baseline glomerular filtration rate (GFR), statin type, and N-acetylcysteine use. Eight RCTs were included for a total of 4,984 patients. The incidence of CI-AKI was 3.91% in the statin group (n = 2,480) and 6.98% in the control group (n = 2,504). In the pooled analysis using a random-effects model, patients receiving statins had 46% lower relative risk (RR) of CI-AKI compared with the control group (RR 0.54, 95% confidence interval [CI] 0.38 to 0.78, p = 001). A moderate degree of non-significant heterogeneity was present (I-2 = 41.9%, chisquare = 12.500, p = 0.099, tau(2) = 0.100). In the subanalysis based on GFR, the pooled RR indicated a persistent benefit with statins in patients with GFR <60 ml/min (RR 0.67, 95% CI 0.45 to 1.00, p = 0.050) and a highly significant benefit in patients with GFR 60 ml/min (RR 0.40, 95% CI 0.27 to 0.61, p <0.0001).
