BACKGROUND: The aim of this study was to investigate early and long-term outcomes of patients with acute coronary syndrome preoperatively requiring intraaortic balloon pump support who underwent emergency off-pump coronary artery bypass graft surgery.
METHODS: One hundred and fifteen patients on preoperative intraaortic balloon pump receiving emergency off-pump coronary artery bypass graft surgery over an 11-year period were evaluated. The median age was 71 years (range, 33 to 87). Acute myocardial infarction and unstable angina were present in 54 patients (47.0%) and 61 patients (53.0%), respectively. Left main disease and triple-vessel disease without left main involvement were present in 74 patients (64.3%) and 33 patients (28.7%), respectively.
RESULTS: There were 3 perioperative deaths. Complete surgical revascularization was accomplished in 82 patients (71.3%), and in situ internal thoracic artery graft was used in 96 (83.5%). Late survival, freedom from major adverse cardiac and cerebrovascular events, and freedom from repeat revascularization rates at 5 years were 83.3%, 73.5%, and 84.2%, respectively. The Cox multivariate prognostic predictors of total mortality were preoperative renal impairment (hazard ratio [HR] 7.90; 95% confidence interval [CI]: 3.06 to 20.4) and low ejection fraction (HR 0.94, 95% CI: 0.88 to 0.99). The multivariate risk predictors of major adverse cardiac and cerebrovascular events were preoperative renal impairment (HR 2.68, 95% CI: 1.00 to 7.19) and peripheral vascular disease (HR 2.81, 95% CI: 1.05 to 7.51), and complete revascularization was protective (HR 0.39, 95% CI: 0.19 to 0.81). The multivariate risk factor of repeat revascularization was previous percutaneous coronary intervention (HR 3.26, 95% CI: 1.14 to 9.33), and complete surgical revascularization was also protective (HR 0.30, 95% CI: 0.11 to 0.85).
CONCLUSIONS: Off-pump coronary artery bypass graft surgery is a feasible option for patients requiring preoperative intraaortic balloon pump support.
