One hundred six consecutive patients underwent elective or emergency
coronary artery bypass grafting (CABG) between January, 1974, and November,
1975. There were 90 men of an average age of 54 years and 16 women an
average of 64 years. Unstable angina (preinfarction angina, angina
decubitus, and crescendo angina) was present in 54 patients of this group
and eight were in congestive heart failure. Sixty-two of the 106 had
previously had myocardial infarctions and four had evolving infarctions.
There were four operative deaths (3.8%) and one early hospital death (less
than 30 days' hospitalization). Perioperative infarction occurred in five
of the survivors. Of the 197 grafts placed in the 101 survivors, 94% were
patent by angiography at 1 to 2 weeks (175 of 187 vein grafts and 10 of 10
left internal mammary grafts). At 1 to 2 years after CABG, 62% of the
survivors consented to repeat angiography at which time 94% of the grafts
were patent (101 of 108 vein grafts and seven of seven left internal
mammary grafts). Clinical follow-up of 81 of the 101 survivors at 1 year
found 99% of them to be asymptomatic or improved. Repeat clinical follow-up
of all survivors (99 of 101) at 3 to 4 years found 93.9% asymptomatic or
improved. Overall survival, including operative deaths, was 92.4% at 4
years.
