How this service works
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.
Output
Returns a single ACEF II numeric score rounded to 4 decimal places, computed as: age/EF + 2.0 (if creatinine > 2.0 mg/dL) + 3.0 (if emergency surgery) + 0.2 × (hematocrit points below 36%, with ≥36% contributing 0). This is the published index value only — not a mortality percentage, not a clearance decision.
Example use cases
Preoperative risk stratification for elective surgery
“I need the ACEF II score for a 65-year-old patient going in for elective cardiac surgery — their EF is 35%, creatinine is 1.4 mg/dL, and hematocrit is 38%. It's not an emergency.”
Emergency CABG risk assessment with renal impairment
“Calculate the Ranucci 2018 ACEF II score for a 78-year-old emergency CABG patient with an ejection fraction of 25%, creatinine of 2.8 mg/dL, and hematocrit of 28%.”
Anemia and low EF risk scoring
“What's the ACEF II score for a 60-year-old patient with EF of 40%, creatinine of 1.1 mg/dL, hematocrit of 30%, and this is elective surgery?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/acef_iiWhen to prefer
Use this endpoint when you need the specific Ranucci 2018 ACEF II formulation for cardiac surgery risk scoring — not the original 2009 ACEF, not a predicted mortality percentage, and not a general operative clearance tool. Ideal for clinical decision-support agents building preoperative assessments that require a validated, published score with creatinine, hematocrit, and emergency-surgery adjustments.
Side effects
- Missing required parameters (age, ejection_fraction_percent, emergency_surgery, hematocrit_percent) returns an error
- Out-of-range values (e.g. age outside 18–120, EF outside 10–80, hematocrit outside 15–60) may be clamped or rejected
- Providing both creatinine_mg_dl and creatinine_umol_l simultaneously returns an error
- Invalid types (e.g. non-integer age) cause schema validation failure
- Payment failure (insufficient USDC balance or x402 issue) blocks the request
