Table 1 EuroSCORE: risk factors, definitions and scores [16]

From: Clinical review: Practical recommendations on the management of perioperative heart failure in cardiac surgery

  Definition Score
Patient-related factors   
   Age Per 5 years or part thereof over 60 years 1
   Sex Female 1
   Chronic pulmonary disease Long-term use of bronchodilators or steroids for lung disease 1
   Extracardiac arteriopathy Any one or more of the following: claudication, carotid occlusion or >50% stenosis, previous or planned intervention on the abdominal aorta, limb arteries or carotids 2
   Neurological dysfunction Disease severely affecting ambulation or day-to-day functioning 2
   Previous cardiac surgery Requiring opening of the pericardium 3
   Serum creatinine >200 μmol/l preoperatively 2
   Active endocarditis Patient still under antibiotic treatment for endocarditis at the time of surgery 3
   Critical preoperative state Any one or more of the following: ventricular tachycardia or fibrillation or aborted sudden death, preoperative cardiac massage, preoperative ventilation before arrival in the anaesthetic room, preoperative inotropic support, intraaortic balloon counterpulsation or preoperative acute renal failure (anuria or oliguria <10 ml/h) 3
Cardiac-related factors   
   Unstable angina Rest angina requiring intravenous nitrates until arrival in the anaesthetic room 2
   LV dysfunction Moderate or LVEF 30 to 50% 1
  Poor or LVEF <30 3
   Recent myocardial infarct <90 days 2
   Pulmonary hypertension Systolic PAP >60 mmHg 2
Operation-related factors   
   Emergency Carried out on referral before the beginning of the next working day 2
   Other than isolated CABG Major cardiac procedure other than or in addition to CABG 2
   Surgery on thoracic aorta For disorder of ascending, arch or descending aorta 3
   Postinfarct septal rupture   4
  1. Application of scoring system: 0-2 (low risk); 3-5 (medium risk); 6 plus (high risk). CABG, coronary artery bypass graft; LV, left ventricular; LVEF, left ventricular ejection fraction; PAP, pulmonary arterial pressure.
