title: Effect of leisure-time physical activity on the prognosis of coronary artery bypass graft surgery.
abstract: OBJECTIVE
  The objective of this study was to evaluate the effect of leisure-time physical activity (LTPA) in the early outcome of coronary artery bypass graft surgery (CABG).
  
  
  METHODS
  This prospective cohort study analyzed 202 patients submitted to CABG. The patients were assigned to two groups, active or sedentary, according to the practice of LTPA in the preoperative period. The independent variable LTPA practiced by the patients in the previous year of the surgery was evaluated. The occurrence of the major adverse cardiac events as death, acute myocardial infarction, reoperation and the hospital stay after surgery were planned to be evaluated.
  
  
  RESULTS
  The mean age of patients was 62 +/- 10 years, and 134 (66%) were men. Sixty-six (33%) patients practiced LTPA and were classified as active, and 136 (67%) were sedentary. The active group showed 78% less probability (OR= 0.22; CI 95%: 0.09-0.51) to suffer a MACE P<0.001 and a reduction of 33% in length of hospital stay as compared for sedentary patients (HR= 0.67; IC 95%: 0.49 - 0.93). P= 0.018.
  
  
  CONCLUSIONS
  LTPA is an important predictor of major adverse cardiac events and hospital stay.
