| English abstract | Background: Coronary artery bypass grafting (CABG) is the treatment of choice for a broad spectrum of patients with coronary disease. Aim: To describe global survival and factors associated with lower long-term survival in patients operated with isolated CABG. Material and Methods: Analysis of a cohort of patients who underwent CABG between January 2006 and December 2008 at a public hospital. The database and operation records of 1.003 cardiac surgeries were reviewed. Of these, an isolated CABG was performed in 658 patients aged 62 ± 9 years including 516 male (78%). Survival data were obtained from the Chilean Civil Registry Office and a complete ten-year follow up was accomplished. Survival was analyzed with Kaplan-Meier method with log-rank test and Cox regression. Results: Operative mortality occurred in 13 patients (2%). Survival at 1, 3, 5 and 10 years was 97, 94, 91 and 76%, respectively. One, 3, 5 and 10-year free of cardiovascular death survival was 98, 97, 95 y 89%, respectively. Factors associated with long-term survival were chronic kidney disease in hemodialysis (Hazard ratio (HR) 7.9; 95% confidence intervals (CI) 4.6-13.6), chronic obstructive pulmonary disease (HR 2.3; 95% CI 1.4-3.7), chronic arterial occlusive disease (HR 2.2; 95% CI 1.4-3.4) and diabetes mellitus (HR 1.9; 95% CI 1.4-2.6). According to EuroSCORE, 10-year survival was 86, 75 and 62% (p < 0.01) in low, medium and high-risk patients, respectively. Conclusions: These patients had a 10-year survival comparable to large international series. Groups associated with lower 10-year survival were identified |
