During 1972 to 1974, 686 men aged 27 to 67 years, admitted to thirteen
Veterans Administration Hospitals with stable angina, resting or exercise
electrocardiographic abnormalities, "graftable" arteries, and abnormal left
ventricular function (80 percent) were randomly assigned to surgery (332)
or medical (354) treatment. There was no significant difference in
clinical, angiographic, and ventriculographic characteristics. The over-all
operative mortality rate (30 days) was 5.8 percent, 5 percent in the 95
percent who had saphenous vein aorta- coronary bypass alone. Eighty-nine
percent of the 79 percent recatheterized at 1 year had at least one patent
graft. Longevity for patients with one, two, and three vessel disease who
were treated surgically was comparable to that previously described, but
did not differ from that of the medically treated groups. Survival in the
over- all surgical group was 86 percent at 4 years as compared to 83
percent in the medical group, which in these "operative candidates" is
better than usually cited. This difference was eliminated when the 90
patients (13 percent) with left main disease, whose longevity was
significantly improved (p = 0.005) by the operation, were excluded. Despite
this exclusion, a slight trend in favor of surgery was still discernible in
the largest subgroup, those having triple vessel disease with an abnormal
left ventricle.
