[Coronary artery bypass in octogenarians; how to reduce operative mortality and enhance long-term quality of life].
Octogenarians are at increased risk for perioperative morbidity and mortality after coronary artery bypass. This study is aimed to elucidate the suitable operative strategy and perioperative management. A retrospective analysis was conducted of 54 consecutive patients with 80-years of age or older, who underwent elective isolated coronary artery bypass between May 1999 and May 2008. Mean follow-up was 43.3 months and 96.3% complete. Operavive mortality was 3.7% and the incidence of stroke was 3.7%. The 7-year cardiac survival was 80.4% and the 7-year cardiac event free was 65.0%. The use of arterial graft to the right coronary artery was identified as independent predictor of late cardiac event. Neither total arterial revascularization nor bilateral internal thoracic artery grafting was a significant cardiac event factor. This retrospective study suggests a benefit of the less invasive strategy in terms of operative mortality and morbidity. Application of fast-track treatment in octogenarians appears to be an effective approach to reduce perioperative morbidity and enhance long-term quality of life.
