Long-term outcomes and risk analyses of coronary bypass for left main disease

Background:We retrospectively analyzed the long-term outcomes and risk predictors of conventional coronary artery bypass grafting routinely employed for patients with left main disease.Methods:From January 2000 through December 2009, conventional coronary artery bypass grafting was routinely employed in 193 consecutive patients with left main disease. Long-term analyses were performed, looking at the primary endpoint of major adverse cardiac and cerebrovascular events which included all-cause death, stroke, myocardial infarction, and repeat revascularization. We also analyzed the effects of variables on major adverse cardiac and cerebrovascular events at 9 years after the operation.Results:The overall 9-year rates of combined outcomes (death, stroke, myocardial infarction), repeat revascularization, and major adverse cardiac and cerebrovascular events were 20.2%, 8.9%, 27.7%, respectively. The SYNTAX score was demonstrated to be the only significant predictor of combined outcomes at 9 years (hazard ratio ...
