    Formula

    ACEF II = (A / EF) + C + Em + Hct, where variables are as follows:

    Variable

    Notes

    A

    Age, years

    --

    EF

    Left ventricular ejection fraction, %

    On most recent assessment

    C

    Serum creatinine, 2 points if >2.0 mg/dL (177 µmol/L); 0 if ≤2.0 mg/dL

    Last recorded value before surgery

    Em

    Emergency surgery, 3 points if yes; 0 if no

    Emergency = operation required before the beginning of the next working day after decision to operate

    Hct

    0.2 x (36 - hematocrit); 0 if hematocrit ≥36%

    Last recorded value before surgery


    Facts & Figures

    Interpetation: 

    Predicted 30-day operative mortality = ex / (1 + ex)

    where x = -4.86 + 0.75 x ACEF II
