EuroSCORE II calculator

Clinical inputs

• Age (years)Accepted range: 18 to 100
• Sex
• Renal function
• Extracardiac arteriopathy (claudication, carotid occlusion/>50% stenosis, prior/planned aortic or peripheral arterial intervention)
• Poor mobility (severe impairment of mobility affecting day-to-day function)
• Previous cardiac surgery requiring pericardial opening
• Chronic pulmonary dysfunction (long-term bronchodilator/steroid use for lung disease)
• Active endocarditis
• Critical preoperative state (e.g. VT/VF or aborted SCD, preop cardiac massage, preop ventilation, preop inotropes/IABP, preop acute renal failure)
• Diabetes on insulin
• NYHA class
• CCS class 4 angina (angina at rest)
• LV ejection fraction
• Recent myocardial infarction (≤90 days before surgery)
• Pulmonary hypertension
• Urgency of operation
• Weight of the intervention
• Surgery on thoracic aorta

Nashef SAM, Sharples LD, Vernersson E, Lazam S, Kunst G, Milojevic M, et al. EuroSCORE II. DOI: 10.1093/ejcts/ezs043. PMID: 22378703. Scope: Full EuroSCORE II logistic regression model: p = 1/(1+e^-L), L = -5.324537 + 0.0285181*(1 if age<=60 else age-59) + sum of published coefficients for sex, renal function, extracardiac arteriopathy, poor mobility, previous cardiac surgery, chronic pulmonary dysfunction, active endocarditis, critical preoperative state, insulin-dependent diabetes, NYHA class, CCS class 4 angina, LV ejection fraction, recent MI, pulmonary hypertension, urgency, weight of intervention, and thoracic aortic surgery (Table 6 of the cited source); outputs predicted operative mortality (%). Coefficients cross-checked against the EuroSCORE Study Group's own published formula page (euroscore.org) and an independent third-party reproduction of Table 6; no published worked numeric example (specific inputs with a stated resulting percentage) was found to validate end-to-end, so this should be spot-checked against the official euroscore.org calculator before clinical reliance.
