contrast-induced nephropathy
Also written as: CIN — Contrast-Induced Nephropathy
Acute kidney injury occurring after exposure to iodinated contrast media during cardiac procedures.
Full Definition
Contrast-induced nephropathy (CIN) is a form of acute kidney injury that develops following exposure to iodinated contrast agents used in cardiac catheterisation and intervention. It is typically defined as an increase in serum creatinine of 25% or 0.5 mg/dL within 48-72 hours of contrast exposure. Risk factors include pre-existing renal impairment, diabetes, advanced age, and dehydration. Prevention strategies include adequate hydration, minimising contrast volume, and considering alternative imaging modalities in high-risk patients.
Usage
Usage note: Hyphenate the full term. CIN is the preferred abbreviation. Some literature uses CA-AKI (contrast-associated acute kidney injury).
