We reviewed 223 cases of isolated coronary
artery bypass grafting (CABG) during the past 6 years, and used the EuroSCORE
to assess the differences in clinical outcomes between off-pump CABG (OPCAB)
and on-pump CABG (conventional CABG: CCABG). After March 2000, our first
choice has been OPCAB, with CCABG selected only for cases with unstable
hemodynamics. The total of 223 isolated CABG cases consisted of 129 OPCAB
and 94 CCABG, but after March 2000, 94 OPCAB and 42 CCABG were performed.
Mean EusoSCORE was 5.8 for OPCAB and 4.1 for CCABG, and corresponding
expected survival rates were 7.20% and 5.04%. The 3 cases of hospital
death (mortality, 1.3%) all belonged to the earlier CCABG groups and
were not related to cardiac death. After March 2000, no hospital deaths
occurred in either group. Midterm results showed 5 deaths, but these
were not related to cardiac death, either. There were no significant
differences between the 2 groups in terms of hospital complications other
than long mechanical ventilation time, which was markedly longer only for
the OPCAB groups (p＜0.01). Mean number of grafts was significantly high
for patients in the CCABG groups (OPCAB 2.1 vs. CCABG 2.8; p＜0.05).
We have therefore been using OPCAB for high-risk cases, and midterm
results of our CABG patients were satisfactory.
