Incidence of contrast-induced acute kidney injury associated with diagnostic or interventional coronary angiography.

Background: Contrast-induced acute kidney injury (CI-AKI) represents an important cause of hospital-acquired AKI. The aim of this study was to evaluate the incidence of CI-AKI after coronary angiography (CA) or percutaneous coronary intervention (PCI) and the role of patient-/procedure-related risk factors.

Methods: For 11 months, patients undergoing CA or PCI were prospectively evaluated for CI-AKI, and factors possibly affecting CI-AKI were analyzed.
