title: [Coronary artery bypass grafting in patients over 70 years old].
abstract: OBJECTIVE
  To retrospectively analyze the experiences, indications, technique, and results of coronary artery bypass grafting (CABG) in patients over 70 years old.
  
  
  METHODS
  Ninety-one patients received coronary artery bypass grafting from March 2004 to March 2008. Ages ranged from 70 to 83 years old, 22 patients over 75 years old. Conventional CABG (CCABG) in 72 patients, off-pump CABG (OPCAB) in 19 patients. Clinical data has no significant differences in two groups. The rate of using left internal mammary artery was 96.7%. The number of grafts in CCABG and OPCAB group were 2 to 5 (3.5 +/- 0.8) and 1 to 4 (2.9 +/- 0.7) respectively.
  
  
  RESULTS
  In-hospital death in 2 cases, both were from chronic obstructive pulmonary disease and pulmonary infection. Cerebral infarction in 1 case and pulmonary infection in 2 cases in CCABG group, but no significant difference between two groups, and no difference in intubation, ICU stay, respiratory failure, renal function failure. But number of grafts in CCABG was significantly more than that in OPCAB (P < 0.01). Postoperative follow-up was 3 to 36 months, 1 case with recurrent angina in OPCAB.
  
  
  CONCLUSIONS
  According to the characteristic of coronary artery disease in elderly, fully revascularization and improving myocardial blood supply, patients over 70 years old with CABG can obtain the same efficacy as younger patients. There were not significant difference between CCABG and OPCAB.
