BACKGROUND: Elderly patients with obstructive coronary disease are frequently a clinical dilemma, usually in need of management for multiple comorbidities. The present study aims at evaluating the short- and long-term survival of Brazilian octogenarians treated with coronary angioplasty. METHODS: A total of 246 consecutive patients aged > 80 years, treated with percutaneous coronary intervention in the Brazilian Public Health System comprise the study population. Baseline and procedural characteristics were collected prospectively. After discharge the occurrence of death was evaluated through the review of medical records and phone contact. RESULTS: Mean age was 83.7 ± 3.0 years (range 80 years to 94 years). The overall survival at 30 days, 1 year, and 2 years were 86.7%, 78.1% and 76.0%, respectively. Only acute infarction at admission and the presence of triple-vessel disease were identified as multivariate predictors of death (Infarction at admission: adjusted HR 1.76; 95%CI 1.08 - 2.87; p=0.02. Triple-vessel disease: adjusted HR 1.83; 95%CI 1.12 - 2.99; p=0.02). Patients without infarction at admission or triple-vessel disease reported an 85.7% survival rate after 2 years, while only 56.8% were alive after 2 years when both conditions were present. CONCLUSIONS: Octogenarians treated with coronary angioplasty report an overall high mortality rate, especially in the first year post-procedure. However, the subgroup of patients who are not high risk shows good survival rate along the first two years after the procedure.
