The probability of in-hospital mortality after coronary artery bypass graft (CABG) surgery can be predicted based on clinical and physiologic measurements.
Parameters:
(1) age in years
(2) gender
(3) body surface area in square meters
(4) Charlson comorbidity score (J Chron Dis. 1987; 40: 373-383)
(5) history of prior CABG operation
(6) ejection fraction score
(7) left ventricular end diastolic pressure (LVEDP)
(8) priority at surgery
