Periprocedural effects of statins on the incidence of contrast-induced acute kidney injury: A systematic review and trial sequential analysis.

Contrast-induced acute kidney injury (CI-AKI) is a potential complication in coronary angiography (CAG) and percutaneous coronary interventions (PCI). Prior randomized controlled trials (RCTs) have suggested that statins may play a role in reducing rates of CI-AKI, however it is not clear how firm the current evidence is.
