title: [Off-pump myocardial revascularization in the elderly: analysis of morbidity and mortality].
abstract: OBJECTIVE
  To analyze the in-hospital outcome of elderly patients aged 70 years and older who underwent off-pump coronary artery bypass graft surgery with an intraluminal shunt in urgent, emergent, and elective coronary revascularizations.
  
  
  METHODS
  From July 1989 to July 2005, we analyzed 87 patients ranging in age from 70 to 92 years. Of the 87 patients enrolled, 50 (57.5%) patients had unstable angina, with three (3.4%) acute myocardial infarction; thirty-one (35.6%) patients underwent urgent and emergent surgery; thirteen (14.9%) patients had myocardial infarction in less than 30 days, and 34 (39.1%) in more than 30 days.
  
  
  RESULTS
  The main postoperative complications were: atrial fibrillation (32.2%), heart failure (12.6%), pneumonia (10.3%), septicemia (3.4%), acute myocardial infarction (2.3%), mediastinitis (1.1%) transient ischemic attack (1.1%), and pneumothorax (1.1%). The mean extubation time was 18.50+/-19.09 hours, the length of stay in the intensive care unit was 2.92+/-2.03 days, and hospital length of stay was 10.55+/-7.16 days. Packed red cells were given to nine (10.34%) patients and none of them was operated due to bleeding. The in-hospital mortality was 4.6%.
  
  
  CONCLUSIONS
  In patients over 70 years-old, elective and non-elective off-pump coronary artery bypass grafting with intracoronary shunt showed to be safe and effective, associated with low rates of postoperative complications and mortality in relation to the studied population.
