Although quality assessment of coronary arterypatients can be done by 30 days risk-adjusted operative mortality, it is still insufficient to study the outcome after primary coronary artery bypassgraftsurgery (CABG). In our study, we attempted to determine the factors, which can help predict operative mortality before and after CABG.
METHODS:
The study population consisted of 1000 prospective patientswho underwent primary isolated CABG. Assessment was done by dividing the patients into two groups, i.e. non-survivors ( n= 12) and survivors ( n= 988). Data were analyzed using both univariate and multivariate models.
Our data suggest that operative mortality can be predicted prior to and after surgery considering factors such as LVEF, use of IABC, onset of ventricular arrhythmias and low CO.
