In 1983 and 1984, coronary artery bypass grafting (CABG) was performed on
107 consecutive patients for postinfarction angina. In each instance, CABG
was done within 30 days of infarction. Sixty-three patients (59%) required
intravenous administration of nitroglycerin and/or the intraaortic balloon
pump (IABP) for relief of angina. Oral medications relieved angina in the
remaining 44 patients. Thirty-eight patients underwent CABG 7 days or less
after the infarction (Group 1), 25 received it between 8 and 15 days later
(Group 2), and 44 had CABG between 16 and 30 days later (Group 3). There
were 9 in-hospital deaths: 4 in Group 1, 2 in Group 2, and 3 in Group 3.
Thirteen patients needed the IABP for hemodynamic stability as well as
relief of angina. Even when the patient was stable hemodynamically, death
was more likely to occur among these 13 patients if CABG was conducted
within 7 days of infarction. Follow-up was 94% complete at 29.4 months.
Eighty-six percent of patients were asymptomatic or in New York Heart
Association Functional Class I, and 6% were in Class II. There were 2 late
deaths. CABG for angina can be accomplished within 30 days of an acute
infarction with good results. The exception to this rule is the patient in
whom shock develops after a myocardial infarction and who, despite
stabilization, receives CABG within 7 days of the infarction.
