Abstract

The clinical characteristics, perioperative complications and medium term outcome were analysed for patients undergoing emergency coronary artery bypass surgery (CABG) following failed coronary angioplasty (PTCA). Seven hundred and twenty PTCAs were performed from June 1981 to June 1989, of which 30 (4.2%) resulted in CABG within four hours of PTCA. The perioperative course and follow-up were compared to 30 patients undergoing elective CABG, matched retrospectively for age, sex, month of operation and number of grafts. The emergency group had a tendency to more post operative bleeding, but no increased incidence of early reoperation for bleeding, and had a high incidence of periprocedural Q wave infarction (20% vs 3%, p less than 0.05). The emergency group had shorter bypass time and decreased use of the internal mammary artery (7% vs 50%, p less than 0.05). There was one in-hospital death in the emergency group. At medium term follow-up (3.4 +/- 2.4 years, range two months to eight years) there was one late death in each group, and seven patients in each group had return of angina or congestive heart failure. Twenty-one patients in the emergency group and 22 patients in the elective group were asymptomatic on no cardiac medications. We conclude that patients with failed PTCA requiring emergency CABG are more likely than an elective group to have post operative bleeding but no increased risk of early reoperation, and have a higher incidence of perioperative Q wave infarction.(ABSTRACT TRUNCATED AT 250 WORDS)
