Table 1 EuroScore (4)
From: Is age an independent determinant of mortality in cardiac surgery as suggested by the EuroSCORE?
Variable | Definition and Scoring | |
|---|---|---|
Patient-related factors | ||
Age (years) | Per 5 years or part thereof over 60 years | 1 |
Gender | Female | 1 |
Chronic pulmonary disease (COPD) | 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 | Surgery requiring opening of the pericardium | 3 |
Serum creatinine | Serum creatinine > 200 μmol/l preoperatively | 2 |
Active endocarditis | Patient still on antibiotic treatment for endocarditis at 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 anaesthetic room, preoperative inotropes or intra-aortic balloon pump, preoperative acute renal failure (anuria or oliguria <10 ml/h) | 3 |
Cardiac-related factors | ||
Unstable angina | Rest angina requiring intravenous nitrates until arrival in anaesthetic room | 2 |
Left ventricular dysfunction | Moderate or left ventricular ejection fraction 30–50% Poor or left ventricular ejection fraction <30% | 13 |
Recent myocardial infarction | Myocardial infarction within 90 days | 2 |
Pulmonary hypertension | Systolic pulmonary artery pressure >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 disorders of ascending, arch or descending aorta | 3 |
Postinfarction septal rupture | 4 | |
Score | Risk | Expected mortality (95% confidence limits) |
0–2 | Low | 1,27–1,29% |
3–5 | Medium | 2,90–2,94% |
≥ 6 | High | 10,93–11,54% |
