Mortality in isolated coronary artery bypass surgery in elderly patients. A retrospective analysis over 14 years

We aim to describe our experience in coronary artery bypass graft in elderly patients older than 80 years and assess the associated risk and predictors of mortality in this subgroup. From January 1999 to June 2013, 3097 patients underwent consecutive coronary artery bypass graft surgery. Patients aged over 80 years were identified. Multivariate survival analysis using Cox's regression model was performed. We identified 99 patients older than 80 years (80-group; mean age 82±3.5 years) and 2957 younger than 80 years (control group) (mean age 64.2±9.7 years). Additive EuroSCORE was 8.4±4.8 and 4.6±4.6 (P
