ACEF II Risk Score for Cardiac Surgery

CardiologyCardiac surgeryPerioperative riskBeta toolThis tool is in beta. It has undergone internal validation but still requires additional testing. Always confirm the data entered and the results obtained before clinical use. It should not be used as the sole basis for clinical decisions.
Adult use only; enter age >= 18 years.
years
Must be greater than 0 because LVEF is in the denominator of the score.
%
The renal term adds 2 points only when creatinine is strictly greater than 2.0 mg/dL.
mg/dL
The anemia term adds 0.2 x (36 - hematocrit) only when hematocrit is strictly below 36%.
%
Emergency surgeryUse Yes only when the case meets the source-defined emergency-surgery concept.

Clinical noticeEducational preoperative risk support only. Interpret the raw ACEF II score as supplemental context rather than a stand-alone operative decision.

Context and use

ACEF II = age / LVEF + 2 if creatinine > 2.0 mg/dL + 3 if emergency surgery + 0.2 x (36 - hematocrit) if hematocrit < 36%

The result is presented as a numeric ACEF II score, rounded to 2 decimal places.

Do not convert this score into a mortality percentage or low, intermediate, or high risk categories.
