BACKGROUND: Emergent coronary artery bypass grafting (CABG) remains a high-risk procedure in cardiac surgery. Therefore we performed this study to evaluate its current results. METHODS: From 2001 to 2007, fifty-seven patients with an acute coronary syndrome underwent an isolated CABG procedure emergently. Data were collected retrospectively from the patients' charts. RESULTS: The mean age of the patients, 45 males (79%) and 12 females (21%), was 64.5 ± 11.5 years. Operations were performed on 40 patients (70%) with cardiopulmonary bypass (CPB) and cardioplegic cardiac arrest and on 6 without CPB. Eleven patients (11%) underwent on-pump beating heart procedures (19%). The operating times (minutes) were duration of surgery 215.2 ± 64.2; duration of CPB 116.9 ± 51.5; and X-clamp time 57.3 ± 19.9. The mean number of grafts per patient was 2.95 ± 0.97. Postoperative durations of mechanical ventilation (hours), Intensive Care Unit stay (days), and normal ward stay (days) were 45.8 ± 75.3, 8.9 ± 23.1, and 9.6 ± 8.0, respectively. The total number of complications was 57, and postoperative confusion (29.8%), revision for bleeding (22.8%), and renal insufficiency (21%) occurred most frequently. Seven of the 57 patients died: 5 succumbed to multiorgan failures, 1 to cardiac decompensation, and 1 to bleeding complications. CONCLUSION: Emergent CABG is associated with an enhanced perioperative risk, and further developments are absolutely necessary to improve its results.
