Important: The previous additive and logistic EuroSCORE models are out of date. A new model has been prepared from fresh data and is launched at the 2011 EACTS meeting in Lisbon. The model is called EuroSCORE II - this online calculator has been updated to use this new model. If you need to calculate the older "additive" or "logistic" EuroSCORE please visit the old calculator by clicking here.

Notes about euroSCORE II

[1]    Age - in completed years. Some of the weighting for age is now incorporated into the renal impairment risk factor, so it is important that all risk factors are entered to give reliable risk estimations
- see note [2]. Of over 20,000 patients in the EuroSCORE database, only 21 patients were aged over 90 - therefore the risk model may not be accurate in these patients. Please exercise clinical discretion in interpreting the score. The oldest patient in the EuroSCORE database was 95 - EuroSCORE II is not validated in patients over this age.

[2]    Renal impairment - there are now 3 categories based on creatinine clearance calculated using Cockcroft-Gault formula. Unlike serum creatinine in the old EuroSCORE model, some of the weighting for age is directly incorporated into this factor, as age is a component of creatinine clearance. The 3 categories are:

Creatinine clearance (ml/min) =   (140-age (years))   x   weight (kg)   x   (0.85 if female)    /   [72 x serum creatinine (Ámol/l)]

    Weight (and creatinine) have not been directly included in the main EuroSCORE II calculator because they are not direct risk factors in the EuroSCORE II model, other than they contribute to creatinine clearance.

[3]    Extracardiac arteriopathy - one or more of the following

  • claudication
  • carotid occlusion  or >50% stenosis
  • amputation for arterial disease
  • previous or planned intervention on the abdominal aorta, limb arteries or carotids

[4]    Poor mobility - severe impairment of mobility secondary to musculoskeletal or neurological dysfunction

[5]    Chronic lung disease - long term use of bronchodilators or steroids for lung disease

[6]    Active endocarditis  - patient still on antibiotic treatment for endocarditis at time of surgery

[7]    Critical preoperative state   ventricular tachycardia or ventricular fibrillation or aborted sudden death, preoperative cardiac massage, preoperative ventilation before anaesthetic room, preoperative inotropes or IABP, preoperative acute renal failure (anuria or oliguria <10ml/hr)

[8]    CCS class 4 angina    angina at rest

[9]    Recent MI   myocardial infarction within 90 days

[10]  Pulmonary hypertension   systolic pulmonary artery pressure, now in 2 classes

  • moderate: PA systolic pressure (31-55 mm Hg)
  • severe: PA systolic pressure (>55mm Hg)

[11]    Urgency   now four classes:

[12]     Weight of the intervention - include major interventions on the heart such as

  • CABG
  • valve repair or replacement
  • replacement of part of the aorta
  • repair of a structural defect
  • maze procedure
  • resection of  a cardiac tumour
