The age, creatinine, and ejection fraction (ACEF) II Risk Score for cardiac surgery: updated but still parsimonious
Authors' conclusion
The ACEF II allows the inclusion of emergency patients and, through a re-modulation of the coefficients and the inclusion of anaemia, appears more adequate to the present cardiac surgery scenario.
Study context
- Population
- Consecutive cardiac surgery patients; development at one institution, validation at a different institutiondevelopment 7011
- Comparison
- ACEF II vs ACEF vs EuroSCORE II
- Outcome
- Operative mortality (in hospital or 30 days after surgery)
Methodological detailsexternal validation, multivariable logistic regression
- External validation
- Multivariable logistic regression
