title: Outcomes after coronary artery bypass in aged patients.
abstract: OBJECTIVE
  Analyze the octogenarians patients submitted to the surgical myocardium revascularization (CABG) with and without extracorporeal comparing the clinical outcomes and its survival curves.
  
  
  METHODS
  Observational study of the cohort type involving 396 octogenarians submitted to the CABG between 01/01/ 2000 and 01/01/2007. Elaboration of an itinerary for collection of data of the handbooks containing 36 variables. Comparison between groups using t test for independent samples, chisquare and survival curves using Kaplan Meier.
  
  
  RESULTS
  We analyzed 290 patients that possessed appropriate information. The first group G1, of the patients operated without extracorporeal, was constituted of 111 patients and the second group G2, of the operated ones with extracorporeal was constituted of 179 patients. The univariate analyzes had presented statistics significance for the variables: cardiac insufficiency functional class preoperative (P=0.000), tobacco smoking (P=0.050), number of performed grafts (P=0.050), graft type (P=0,000), associates procedures (P=0.000), preoperative use of intra-aortic balloon (P=0.000), hospital mortality (P=0.000) and type of death (P=0.020). In the postoperative outcomes stroke (P=0,036), re-internment for angina (P=0,038). The analyze of the survival curves presented statistic difference (P=0,009).
  
  
  CONCLUSIONS
  Hospital mortality and stroke were bigger in the G2 In the long time the patients of the G1 had respectively presented greater number of re-internments for angina and the late mortality was larger in G2 for the largest prevalence of cardiac deaths.
