    Attention COACH STUDY participants:

    The principal investigators of the study request that you use the official version of the modified score here.

    Mehran Score for Post-PCI Contrast Nephropathy

    Predicts risk of contrast-induced nephropathy (CIN) after percutaneous coronary intervention (PCI).

    INSTRUCTIONS

    Use variables at the time of PCI.

    When to Use
    Pearls/Pitfalls

    Use in patients undergoing PCI. Do not use in patients with pre-existing end-stage renal disease on dialysis or patients with contrast exposure within 1 week of the index procedure.

    In the original study, “contrast-induced nephropathy” was defined as an increase ≥0.5 mg/dL (or ≥25%) in pre-PCI serum creatinine at 48 hours post-PCI.
