Notes about euroSCORE
 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 . 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.
 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:
* 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.
arteriopathy - one or more of the following
 Poor mobility - severe impairment of mobility secondary to musculoskeletal or neurological dysfunction
disease - long term use of bronchodilators or steroids for lung
 Active endocarditis - patient still on antibiotic treatment for endocarditis at time of surgery
 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)
 CCS class 4 angina angina at rest
 Recent MI myocardial infarction within 90 days
hypertension systolic pulmonary
artery pressure, now in 2 classes
now four classes:
 Weight of the intervention - include major interventions on the heart such as
