To predict risk of in-hospital mortality after major cardiac surgery.

The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II predicts risk of in-hospital mortality after major cardiac surgery using the formula: Predicted mortality = e^y / (1 + e^y), where y = -5.324537 + sum(beta_i*x_i), beta_i are factor-specific coefficients, x_i is 0 for absent factors, 1 for present factors, 1 for age ≤ 60 and increases by 1 for each year after 60 (x_i=2 for age 61, 3 for age 62 etc.). The factors used in EuroSCORE II are: Age Gender Renal impairment (creatinine clearance) Extracardiac arteriopathy Neurological or musculoskeletal dysfunction Previous cardiac surgery Pulmonary disease Active endocarditis Critical preoperative state Diabetes on insulin NYHA CCS angina class = 4 LV function Myocardial infarct in previous 4–91 days Pulmonary hypertension Urgent operation Weight of the intervention Thoracic aortic surgery

Use with caution for patients over 95 years as the EuroSCORE II is not validated in patients over this age.
