Coronary Artery Bypass Grafting in Patients Aged 80 Years or Older / 日本心臓血管外科学会雑誌

ABSTRACT

Coronary artery bypass grafting (CABG) in elderly patients has been increasing in recent years. Between June 1981, and February 2004, 32 patients aged 80 years or older (mean 81.8) underwent CABG in our hospital. Twenty one patients (67%) were in New York Heart Association class III or IV. Incidence of emergency surgery in the elderly (17 of 32, 53%) was significantly (<i>p</i><0.0001) higher than that in younger patients (131 of 969, 13.5%). Total hospital deaths were 19% (6 of 32, emergency procedures 5, elective 1). The hospital deaths in patients with an ejection fraction (EF) of 45% or more (5 of 12, 42%) were significantly (<i>p</i><0.05) higher than those in patients with an EF of more than 45% (1 of 20, 5%). The main features of CABG in octogenarians was the high rate of emergency surgery and high mortality. Thus CABG in octogenarians should be performed early, before the cardiac function deteriorates, in order that treatment not be denied because of age alone.
