Background: The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) trial was a non-inferiority trial that compared percutaneous coronary intervention (PCI) using first-generation paclitaxel-eluting stents with coronary artery bypass grafting (CABG) in patients with de-novo three-vessel and left main coronary artery disease, and reported results up to 5 years. We now report 10-year all-cause death results. Methods: The SYNTAX Extended Survival (SYNTAXES) study is an investigator-driven extension of follow-up of a multicentre, randomised controlled trial done in 85 hospitals across 18 North American and European countries. Patients with de-novo three-vessel and left main coronary artery disease were randomly assigned (1:1) to the PCI group or CABG group. Patients with a history of PCI or CABG, acute myocardial infarction, or an indication for concomitant cardiac surgery were excluded. The primary endpoint of the SYNTAXES study was 10-year all-cause death, which was assessed according to the intention-to-treat principle. Prespecified subgroup analyses were performed according to the presence or absence of left main coronary artery disease and diabetes, and according to coronary complexity defined by core laboratory SYNTAX score tertiles. This study is registered with ClinicalTrials.gov, NCT03417050. Findings: From March, 2005, to April, 2007, 1800 patients were randomly assigned to the PCI (n=903) or CABG (n=897) group. Vital status information at 10 years was complete for 841 (93%) patients in the PCI group and 848 (95%) patients in the CABG group. At 10 years, 244 (27%) patients had died after PCI and 211 (24%) after CABG (hazard ratio 1·17 [95% CI 0·97–1·41], p=0·092). Among patients with three-vessel disease, 151 (28%) of 546 had died after PCI versus 113 (21%) of 549 after CABG (hazard ratio 1·41 [95% CI 1·10–1·80]), and among patients with left main coronary artery disease, 93 (26%) of 357 had died after PCI versus 98 (28%) of 348 after CABG (0·90 [0·68–

Aims The purpose of the Euro Heart Survey Programme of the European Society of Cardiology is to evaluate to which extent clinical practice endorses existing guidelines as well as to identify differences in population profiles, patient management, and outcome across Europe. The current survey focuses on the invasive diagnosis and treatment of patients with established coronary artery disease (CAD). Methods and results Between November 2001 and March 2002, 7769 consecutive patients undergoing invasive evaluation at 130 hospitals (31 countries) were screened for the presence of one or more coronary stenosis >50% in diameter. Patient demographics and comorbidity, clinical presentation, invasive parameters, treatment options, and procedural techniques were prospectively entered in an electronic database (550 variables+29 per diseased coronary segment). Major adverse cardiac events (MACE) were evaluated at 30 days and 1 year. Out of 5619 patients with angiographically proven coronary stenosis (72% of screened population), 53% presented with stable angina while ST elevation myocardial infarction (STEMI) was the indication for coronary angiography in 16% and non-ST segment elevation myocardial infarction or unstable angina in 30%. Only medical therapy was continued in 21%, whereas mechanical revascularization was performed in the remainder [percutaneous coronary intervention (PCI) in 58% and coronary artery bypass grafting (CABG) in 21%]. Patients referred for PCI were younger, were more active, had a lower risk profile, and had less comorbid conditions. CABG was performed mostly in patients with left main lesions (21%), two- (25%), or three-vessel disease (67%) with 4.1 diseased segments, on average. Single-vessel PCI was performed in 82% of patients with either single- (45%), two- (33%), or three-vessel disease (21%). Stents were used in 75% of attempted lesions, with a large variation between sites. Direct PCI for STEMI was performed in 410 cases, representing 7% of the
