The outcome of coronary artery bypass grafting surgery among patients hospitalized with acute coronary syndrome: the Euro Heart Survey of acute coronary syndrome experience.
OBJECTIVE
To determine the frequency and outcomes of coronary artery bypass graft (CABG) surgery in patients with a wide spectrum of acute coronary syndromes (ACS).


RESULTS
We prospectively enrolled 10,484 ACS patients from 103 hospitals in 25 countries across Europe and the Mediterranean basin. Of the 10,204 patients with complete data, 460 (4.5%) underwent CABG while in hospital; 3.4% had ST elevation ACS, 5.4% had non-ST elevation ACS, and 4.4% had undetermined ECG ACS (p=0.001 for non-ST elevation ACS vs. others). In general, patients who underwent CABG were more likely to be males, to have diabetes mellitus, hyperlipidemia, a positive family history of premature coronary disease, and prior angina pectoris, but had less often prior heart failure. While in hospital, all CABG patients underwent coronary angiography and 15.2% also underwent percutaneous revascularization, as compared with 51.3 and 33.1% in the remaining patients, respectively. The in-hospital mortality was 3.7% for ACS patients who underwent CABG and 4.8% for non-CABG ACS patients (p=nonsignificant) with an adjusted odds ratio of in-hospital death for CABG patients of 1.00 (95% CI 0.59-1.61).


CONCLUSIONS
Approximately 4.5% of ACS patients underwent CABG during their initial hospitalization, with a greater likelihood among non-ST elevation ACS patients. Of the CABG patients, 15.2% also underwent percutaneous revascularization. The outcome of CABG patients was as good as non-CABG patients, indicating that CABG remains an effective and safe means to achieve revascularization among ACS patients in current clinical practice.
