ObjectivesThe purpose of our study was to investigate the utility of the SYNTAX (Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery) score in aiding patient selection for percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in a large contemporary registry of patients undergoing revascularization of left main coronary artery.BackgroundThe SYNTAX score has been developed as a combination of several validated angiographic classifications aiming to grade the coronary lesions with respect to their functional impact, location, and complexity.MethodsBetween March 2002 and December 2008, 819 patients with left main coronary artery disease underwent revascularization in 2 Italian centers. We compared clinical outcomes of PCI versus CABG in patients with SYNTAX score < or =34 and patients with SYNTAX score >34.ResultsThe rates of 2-year mortality were similar between CABG and PCI in the group of patients with SYNTAX score < or =34 (6.2% vs. 8.1%, p = 0.461). Among patients with SYNTAX score >34, those treated with CABG had lower rates of mortality (8.5% vs. 32.7%, p < 0.001) than those treated with PCI. After statistical adjustment, revascularization by PCI resulted in a similar risk of death compared with CABG in patients with SYNTAX score < or =34 (hazard ratio: 0.81, 95% confidence interval: 0.33 to 1.99, p = 0.64) and in a significantly higher risk in patients with SYNTAX score >34 (hazard ratio: 2.54, 95% confidence interval: 1.09 to 5.92, p = 0.031).ConclusionsA SYNTAX score threshold of 34 may usefully identify a cohort of patients with left main disease who benefit most from surgical revascularization in terms of mortality.
