CIN
Also written as: CIN — Contrast-Induced Nephropathy
Acute kidney injury following contrast media exposure during cardiac procedures.
Full Definition
Contrast-Induced Nephropathy represents acute deterioration in kidney function following intravascular contrast media administration, typically defined as a rise in serum creatinine of 25% or 0.5 mg/dL within 48-72 hours post-procedure. CIN is a significant complication of cardiac catheterization and CT angiography, particularly in patients with pre-existing kidney disease, diabetes, or heart failure. Risk stratification involves assessing baseline renal function, contrast volume, and patient-specific factors. Prevention strategies include pre-procedural hydration, contrast volume minimization, and use of iso-osmolar contrast agents. CIN can lead to prolonged hospitalization and long-term kidney dysfunction.
Usage
Usage note: Always specify baseline and post-procedure creatinine values when documenting CIN.
