Contrast-Induced Nephropathy Risk Score

Contrast-Induced Nephropathy Risk Score, Risk Score for Prediction of Contrast-Induced Nephropathy After Percutaneous Coronary Intervention

Risk calculation is based on outcomes from contrast exposure with Percutaneous Coronary Intervention (PCI)

Points 5: Congestive Heart Failure
1. NYHA Class III or IV or
2. Pulmonary Edema history
Points 5: Hypotension
1. Systolic Blood Pressure <80 mmHg for greater than one hour and
2. Required inotropic medication support or intra-aortic balloon pump
Points 5: Intra-Aortic Balloon Pump
Points 4: Age over 75 years old
Points 3: Anemia
1. Men: Baseline Hematocrit <39%
2. Women: Baseline Hematocrit <36%
Points 3: Diabetes Mellitus
Points ?: Contrast Media Volume
1. Assign 1 point for every 100 ml of Contrast Media administered
Points ?: Decreased GFR <60 ml/min/1.73m2
1. Assign 2 points for eGFR 40-60 ml/min/1.73m2
2. Assign 4 points for eGFR 20-40 ml/min/1.73m2 (or Creatinine Clearance >1.5 mg/dl)
3. Assign 6 points for eGFR 20-40 ml/min/1.73m2
