[Contrast-induced nephropathy: An update]

Abstract

Contrast-induced nephropathy (CIN) is common in hospitalized patients. Its occurrence is associated with an increased hospitalization stay and cost, morbidity and mortality. Thus, preventives strategies remain a major issue. Patients that are referred for cardiac catheterization are among the most vulnerable to develop CIN due to their comorbidities. Moreover, in some cases, such preventives measures cannot be introduced due to emergent clinical settings. After a summary regarding the properties of iodinated contrast medium, the aim of this work was to review the definition, pathophysiology, diagnosis and preventive strategies related to CIN.
