Mitigating contrast-induced acute kidney injury associated with cardiac catheterization.

Contrast-induced nephropathy, also referred to as contrast-induced acute kidney injury (CIAKI), is among the most common causes of AKI, especially in patients with underlying chronic kidney disease. In addition to the increased cost engendered by the development of CIAKI, several studies have suggested the occurrence of AKI after cardiac procedures is associated with an increase in both morbidity and mortality. This increase in morbidity and mortality occurs after both intravenous and intra-arterial studies. This review focuses on relevant proposed pathophysiological mechanisms, risk factors, and current prophylactic strategies, which may reduce the incidence of CIAKI during cardiac angiographic imaging studies.
