Multicenter Study Clinical TrialSafety and effectiveness of the Endeavor zotarolimus-eluting stent in real-world clinical practice: 12-month data from the E-Five registry.
The E-Five registry was designed to evaluate the safety and effectiveness of the Endeavor zotarolimus-eluting stent (ZES) (Medtronic CardioVascular, Santa Rosa, California) for the treatment of coronary artery stenosis across a wide range of patients treated in real-world clinical practice settings. ⋯ This large, international multicenter registry provides important information regarding the long-term safety and efficacy of the Endeavor ZES across standard and extended-use patients in the real-world setting. Rates of MACE and measures of safety including cardiac death, myocardial infarction, and stent thrombosis were low and consistent with pooled results of clinical trials. (E-Five Registry: A World-Wide Registry With The Endeavor Zotarolimus Eluting Coronary Stent [eFive Registry]; NCT00623441).

Randomized Controlled Trial Multicenter Study Comparative StudyClinical and angiographic outcomes in diabetics from the ENDEAVOR IV trial: randomized comparison of zotarolimus- and paclitaxel-eluting stents in patients with coronary artery disease.
The aim of this study was to examine outcomes related to the use of the Endeavor zotarolimus-eluting stent (ZES) (Medtronic CardioVascular, Santa Rosa, California) compared with the TAXUS paclitaxel-eluting stent (PES) (Boston Scientific Corp., Natick, Massachusetts) in the 477 patients with diabetes mellitus (DM) enrolled in the randomized ENDEAVOR IV (Randomized Comparison of Zotarolimus- and Paclitaxel-Eluting Stents in Patients with Coronary Artery Disease) trial. ⋯ One-year clinical outcomes were similar among DM patients treated with ZES and PES in the ENDEAVOR IV trial. These findings parallel the overall trial results, which demonstrated similar efficacy and safety of ZES and PES for single de novo coronary lesions.

Randomized Controlled Trial Multicenter Study Comparative StudyRandomized comparison of primary percutaneous coronary intervention with combined proximal embolic protection and thrombus aspiration versus primary percutaneous coronary intervention alone in ST-segment elevation myocardial infarction: the PREPARE (PRoximal Embolic Protection in Acute myocardial infarction and Resolution of ST-Elevation) study.
The purpose of this study was to evaluate the effectiveness of combined proximal embolic protection with thrombus aspiration (Proxis Embolic Protection System [St. Jude Medical, St. Paul, Minnesota]) in ST-segment elevation myocardial infarction patients. ⋯ There was no significant difference in complete STR at 60 min in this proof-of-concept study. However, we observed a significant difference in immediate complete STR in Proxis-treated patients, better STR at later time points, and a reduction of electrocardiogram injury current over time, compared with control patients. The results suggest that primary PCI with the Proxis system may lead to better immediate microvascular flow in ST-segment elevation myocardial infarction patients. (The PREPARE Study; ISRCTN71104460).

Multicenter Study Clinical Trial2-year results of the AUTAX (Austrian Multivessel TAXUS-Stent) registry beyond the SYNTAX (synergy between percutaneous coronary intervention with TAXUS and cardiac surgery) study.
The multicenter AUTAX (Austrian Multivessel TAXUS-Stent) registry investigated the 2-year clinical/angiographic outcomes of patients with multivessel coronary artery disease after implantation of TAXUS Express stents (Boston Scientific, Natick, Massachusetts), in a "real-world" setting. ⋯ With the aim of complete revascularization, TAXUS stent implantations can be safe for patients with multivessel disease. The AUTAX registry including patients with post-PCI lesions provides additional information to the SYNTAX (Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery) study. (Austrian Multivessel TAXUS-Stent Registry; NCT00738686).

Multicenter Study Comparative StudyUsefulness of SYNTAX score to select patients with left main coronary artery disease to be treated with coronary artery bypass graft.
The 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. ⋯ A 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.
