EuroSCORE II, the gold standard for predicting mortality risk in cardiac surgery patients.
EuroSCORE II Calculator
Predicting Operative Mortality in Cardiac Surgery
The EuroSCORE II is a risk prediction model used to calculate the risk of death after cardiac surgery. It helps surgeons and patients make informed decisions and compare surgical performance across different centers.

EuroSCORE II Results
Interpretation
The EuroSCORE II predicts the risk of death after adult cardiac surgery. This patient has a low predicted mortality risk based on the provided parameters.
Key Risk Factors
- No significant risk factors identified
Clinical Implications
- Standard preoperative preparation is appropriate
- Proceed with surgery as planned with standard monitoring
- Inform patient of favorable risk profile
EuroSCORE II (European System for Cardiac Operative Risk Evaluation II) is a risk prediction model specifically designed to estimate in-hospital mortality for patients undergoing cardiac surgery. It is the updated version of the original logistic EuroSCORE, refined to improve predictive accuracy in contemporary cardiac surgical practice.
Purpose and Clinical Utility
- Risk Stratification: Quantifies individual patient’s surgical risk
- Informed Consent: Helps clinicians communicate risks to patients and families
- Surgical Decision-Making: Aids in selecting appropriate treatment strategies
- Quality Assurance: Allows comparison of surgical outcomes across institutions
- Resource Planning: Helps anticipate postoperative care needs
Key Components and Variables
EuroSCORE II incorporates 18 patient-specific and procedure-specific factors:
Patient-Related Factors
- Age (continuous variable)
- Gender
- Renal Impairment (creatinine level or dialysis)
- Extracardiac Arteriopathy (claudication, carotid disease, previous vascular surgery)
- Poor Mobility (severe impairment of mobility secondary to musculoskeletal or neurological dysfunction)
- Previous Cardiac Surgery
- Chronic Lung Disease (based on FEV1 or clinical assessment)
- Active Endocarditis (patient still under antibiotic treatment)
- Critical Preoperative State (includes: VT/VF, resuscitation, inotropes, IABP, ventilation, acute renal failure)
Cardiac-Related Factors
- NYHA Functional Class
- CCS Angina Grade 4
- Left Ventricular Function (LVEF)
- Recent Myocardial Infarction (<90 days)
- Pulmonary Hypertension (systolic PA pressure)
Operation-Related Factors
- Urgency of Surgery
- Weight of Procedure (isolated CABG, single non-CABG, multiple procedures)
- Surgery on Thoracic Aorta
- Other than Isolated CABG
Scoring System and Interpretation
| EuroSCORE II | Risk Category | Clinical Implications |
|---|---|---|
| < 2% | Low Risk | Standard preoperative preparation |
| 2-5% | Medium Risk | Careful optimization, enhanced monitoring |
| 5-10% | High Risk | Multidisciplinary discussion, advanced planning |
| > 10% | Very High Risk | Consider alternatives, extensive counseling |
Calculation Method
- Uses logistic regression equation with specific coefficients for each variable
- More accurate than original EuroSCORE, especially in high-risk patients
- Available as online calculators, mobile apps, and integrated into hospital systems
Advantages Over Original EuroSCORE
- Improved Calibration: Better predicts actual mortality rates
- Contemporary Data: Based on more recent patient populations (2010)
- Simplified Variables: Removed less relevant factors
- Better Discrimination: Enhanced ability to distinguish between risk levels
- Wider Applicability: Valid across different surgical centers and countries
Limitations
- Population-Specific: Derived primarily from European populations
- In-hospital Focus: Does not predict long-term outcomes
- Procedure Limitations: Mainly validated for common cardiac procedures
- Dynamic Factors: Does not account for rapidly changing clinical conditions
- Institutional Variation: Local factors and surgeon experience not incorporated
Clinical Applications
Preoperative Assessment
- Guides patient selection for surgery
- Helps determine surgical timing and urgency
- Assists in planning appropriate level of postoperative care
Surgical Planning
- Influences choice of procedure (e.g., CABG vs. complex procedures)
- Helps decide on need for mechanical circulatory support
- Guides discussion about alternative treatments (e.g., transcatheter options)
Quality Improvement
- Benchmarking surgical performance
- Identifying areas for process improvement
- Research and clinical trials patient selection
Comparison with Other Risk Scores
- STS Score: More complex, US-based, procedure-specific
- ACEF Score: Simpler (age, creatinine, ejection fraction)
- GRACE Score: For ACS patients, not surgical
Practical Implementation
- Routine Use: Recommended for all adult cardiac surgery patients
- Timing: Calculated during preoperative assessment
- Documentation: Should be included in surgical consent process
- Context: Used alongside clinical judgment, not as sole decision-maker
Future Directions
- Integration with frailty assessments
- Incorporation of novel biomarkers
- Machine learning approaches for enhanced prediction
- Procedure-specific refinements
Key Takeaways
EuroSCORE II remains the most widely used cardiac surgical risk model globally, providing a standardized, evidence-based approach to risk assessment that enhances patient safety, facilitates shared decision-making, and supports quality improvement in cardiac surgical care.
