Acute Coronary Syndrome Does Not Have a Negative Impact on Outcomes after Coronary Artery Bypass Grafting in Patients with Left Main Disease

Purpose: Early and long-term outcomes of coronary artery bypass grafting (CABG) in patients with left main disease (LMD) with acute coronary syndrome (ACS) have never been assessed.Methods: Between September 2004 and April 2012, 459 patients with LMD underwent first-time isolated CABG. Of those, 191 patients had ACS and 268 did not. Early and late postoperative outcomes were compared between two groups.Results: Patients in the LMD+ACS group were older and more likely to be female. Left ventricular ejection fraction was lower in the LMD+ACS group. In both groups, bilateral internal thoracic artery grafts were used in over 90% of patients and off-pump technique in over 95%. Operative death rate was not significantly different between the groups (LMD+ACS: 2.1% vs. LMD–ACS: 0.4%). Log-rank test revealed that the actuarial survival rate (79.2 ± 3.7% vs. 81.5 ± 3.5%) and freedom from major adverse cardiac and cerebrovascular events (MACCE) (69.2 ± 4.2% vs. 67.0 ± 4.1%) were similar between groups at 7 years. Multivariate analyses demonstrated that ACS was not identified as an independent predictor of operative death, late mortality, and late MACCE.Conclusion: ACS did not have a negative impact on early and late outcomes of CABG in patients with LMD.
