0454: Prognosis impact of ventricular dysfunction in patients with acute coronary syndrome undergoing surgical revascularization

Background Patients with non-ST elevation acute coronary syndrome complicated by left ventricular dysfunction are a poor prognosis. The aims of our study were to describe the use of surgical revascularization in these high risk patients and to assess the impact of left ventricular dysfunction on long term outcomes. Methods Between 1996 and 2008, we performed elective, isolated, primary CABG in 206 consecutive patients with LVEF≤0.40 complicating acute coronary syndrome. The case group was compared with a group of controls randomly selected (2:1) among the patients who underwent the procedure during this period. Results The analysis of in-hospital course showed a significantly greater all-cause mortality (14.1% vs 7.3%, p Conclusion Surgical revascularization in patients with left ventricular dysfunction complicating acute coronary syndrome is associated with a very high risk of subsequent adverse outcomes and continuing efforts to improve care for these high risk patients are particularly important in terms of diagnosis, revascularization strategy and secondary prevention
