contrast-induced nephropathy
Also written as: CIN — Contrast-Induced Nephropathy
Acute kidney injury following contrast media administration during cardiac imaging procedures, requiring monitoring and prevention strategies.
Full Definition
Contrast-induced nephropathy (CIN) is an acute deterioration in renal function occurring within 48-72 hours after intravascular contrast agent administration, defined as an increase in serum creatinine of ≥0.5 mg/dL or ≥25% from baseline. This complication is of particular concern in cardiac imaging and intervention due to the frequent use of iodinated contrast agents. Risk factors include pre-existing kidney disease, diabetes, dehydration, and advanced age. Prevention strategies include adequate hydration, use of low-osmolar contrast agents, and minimizing contrast volume.
Usage
Usage note: Document baseline renal function and contrast volume used; specify prevention measures employed.
