Materials and Method: This study enrolled 94 octogenerian patients who underwent early coronary artery bypass grafting after acute coronary syndrome between March 2005 and May 2015. The pre-operative and post-operative variables were assesed retrospectively.
Results: Mean age of the patients was 81.8±2.39 years; 53 patients (56.3%) were men and 41 (43.7%) were women. In-hospital mortality rate was 14.8% (14 patients). The factors related with mortality were pre-operative chronic obstructive pulmonary disease (p=0.009); elevated creatinine levels (p=0.004); decreased left ventricular ejection fraction (p=0.045) and use intra-aortic ballon pump support (p<0.001), as well as prolonged post-operative intensive care unit stay (p=0.010). The independent predictors of mortality were pre-operative elevated creatinine level and chronic obstructive pulmonary disease.
Conclusion: Although the mortality rate of coronary artery bypass grafting in octogenerians was higher than that of a younger population, it can be reduced if pre-operative kidney dysfunction and chronic obstructive pulmonary disease are treated with appropriate medications.
