Preoperative profiles, postoperative complications, and the early and late
results in 32 patients 80 yrs of age and older (elderly group) who underwen
t coronary artery bypass grafting were compared with those in patients unde
r 80 yrs of age (control group). In the elderly group, the prevalence of pa
tients with preoperative creatinine clearance (Ccr.) < 50 1/day (34.4%), un
stable angina pectoris (78.1 %) and left main trunk disease (40.1 %) was si
gnificantly higher than those in the control group. The incidences of arrhy
thmia and intensive care unit(ICU) syndrome were also significantly higher
in the elderly group than in the control group, however, there was no death
due to these complications. In the elderly group. one patient (3.1 %) died
in the hospital due to low cardiac output syndrome (LOS), while three pati
ents (2.4 %) of the control group died in the hospital. As for the long-ter
m results, the 5-yr survival rates for the elderly group and the control gr
oup were 82.6 % and 85.2 %. respectively, and the effectiveness of surgery
was remarkable, with improved postoperative activity in 96.9 % of the elder
ly group. These findings indicate that although the elderly patients have h
igher risks by undergoing surgery and have a disadvantage in the rate of po
stoperative complications, the postoperative improvement in activity and su
rvival rate can be similar to those in the younger patients. (C) 2001 The I
