Ranucci 2018 ACEF II for cardiac surgery
Ranucci 2018 ACEF II for cardiac surgery: ACEF II = age/EF + 2.0 if serum creatinine > 2.0 mg/dL + 3.0 if emergency surgery + 0.2 × (hematocrit points below 36%). Hematocrit ≥ 36% contributes 0. Returns the published score only (4 decimals). Not original ACEF 2009, not a predicted-mortality percent, and not an operative clearance.
