    AimsOur aim was to compare, in a large unprotected left main coronary artery (ULMCA) all-comer registry, the long-term clinical outcome after percutaneous coronary intervention (PCI) with first-generation drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) in patients with acute coronary syndrome (ACS).Methods And ResultsOf a total of 2,775 patients enrolled in the Drug Eluting Stents for Left Main Coronary Artery Disease (DELTA) multicentre registry, 379 (13.7%) patients with ACS treated with PCI (n=272) or CABG (n=107) were analysed. Baseline demographics were considerably different in the two groups before propensity matching. No significant differences emerged for the composite endpoint of all-cause death, myocardial infarction (MI), and cerebrovascular accident (HR 1.11, 95% CI: 0.63-1.94; p=0.727), all-cause death (HR 1.26, 95% CI: 0.68-2.32; p=0.462), the composite endpoint of all-cause death and MI (HR 1.02, 95% CI: 0.56-1.84; p=0.956), and major adverse cardiac and cerebrovascular events (HR 0.82, 95% CI: 0.50-1.36; p=0.821). However, a higher incidence of target vessel revascularisation (HR 4.67, 95% CI: 1.33-16.47; p=0.008) was observed in the PCI compared with the CABG group, which was confirmed in the propensity score-matched analysis.ConclusionsIn the DELTA all-comer, multinational registry, PCI for ACS in ULMCA is associated with comparable clinical outcomes to those observed with CABG at long-term follow-up, despite the use of first-generation DES.
