Predicts 30-day mortality after elective or emergency cardiac surgery.
ACEF II = (A / EF) + C + Em + Hct, where variables are as follows:

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 |
Interpetation:
Predicted 30-day operative mortality = ex / (1 + ex)
where x = -4.86 + 0.75 x ACEF II
