Background: Coronary artery bypass grafting (CABG)
reoperation is being performed with increasing frequency.
Objective: To determine the clinical outcome and the
long-term results of a second CABG.
1100-bed urban university-affiliated hospital.
Retrieval of data on selected parameters from medical records before
surgery and prospective follow-up afterwards.
methods: We studied the outcomes of 498 consecutive patients who
underwent CABG reoperation in our institution from January 1978 to
December 1989 and who were followed postoperatively. Their
perioperative mortality, morbidity, and long-term follow-up results
were re-evaluated. The end points of the study were December 1997, 15
years of follow-up, or the patient’s death.
The perioperative mortality rate was 3%. The cumulative survival rates
were 90.1%, 74%, and 63.4% at the 5-year, 10-year, and 15-year
follow-ups, respectively. The cardiac event-free survival rates were
91.5%, 83.4%, and 67.8% at the 5-year, 10-year, and 15-year
follow-ups, respectively. The risk factors adversely affecting
long-term survival were advanced age, hypertension, and a low left
ventricular ejection fraction (LVEF).
long-term results of cumulative survival and cardiac event-free
survival in patients who underwent CABG reoperation are good. Although
this reoperation is safe overall, advanced age, hypertension, and a
decreased LVEF significantly increase the surgical
