BACKGROUND Increased thrombogenicity and smooth muscle cell proliferative response induced by the metal struts compromise the advantages of coronary stenting. The objective of this randomized, multicenter study was to assess whether a reduced strut thickness of coronary stents is associated with improved follow-up angiographic and clinical results. (More)
BACKGROUND Drug-eluting stents are highly effective in reducing the rate of in-stent restenosis. It is not known whether there are differences in the effectiveness of currently approved drug-eluting stents in the high-risk subgroup of patients with diabetes mellitus. METHODS We enrolled 250 patients with diabetes and coronary artery disease: 125 were(More)
CONTEXT In patients with de novo coronary lesions, drug-eluting stents have drastically reduced restenosis risk compared with bare metal stents and conventional balloon angioplasty. It is less clear whether drug-eluting stents are superior to conventional balloon angioplasty for the treatment of patients with in-stent restenosis. OBJECTIVES To assess if(More)
BACKGROUND The clinical benefit of coronary-artery stenting performed in conjunction with coronary angioplasty is limited by the risk of thrombotic occlusion of the stent as well as hemorrhagic and vascular complications of intensive anticoagulation. We compared antiplatelet therapy with conventional anticoagulant therapy with respect to clinical outcomes(More)
BACKGROUND Whether the glycoprotein IIb/IIIa inhibitor abciximab is beneficial in patients undergoing elective percutaneous coronary intervention after pretreatment with clopidogrel is unknown. METHODS We enrolled 2159 patients with coronary artery disease who underwent a percutaneous coronary intervention: 1079 patients were randomly assigned in a(More)
OBJECTIVES The objective of this study was to identify clinical, lesional and procedural factors that can predict restenosis after coronary stent placement. BACKGROUND Coronary stent placement reduces the restenosis rate compared with that after percutaneous transluminal coronary angioplasty (PTCA). However, restenosis remains an unresolved issue, and(More)
BACKGROUND Our rationale for this study was to analyze the risk for procedural failure of attempted stenting and the risk for major adverse cardiac events (MACE) after success and to develop a risk stratification protocol for successful procedures. METHODS AND RESULTS Stenting was attempted in 2894 procedures during the 5-year study period (success in(More)
BACKGROUND Intravenous glucose-insulin-potassium (GIK) may have a positive metabolic influence in patients with acute myocardial infarction (AMI) who receive reperfusion therapy. The objective of this randomized trial was to assess for the first time whether GIK improves myocardial salvage in patients with AMI. METHODS The Reevaluation of Intensified(More)
The objective of this randomized study was to assess whether direct stenting leads to less restenosis than does conventional stenting (CS) with predilation in clinical practice. We included 910 patients who were randomly assigned to undergo either direct stenting (DS; n = 456) or CS (n = 454). No significant difference was observed in the incidence of(More)
PURPOSE To investigate the prognostic value of elevated C-reactive protein levels in patients with stable angina who underwent coronary stenting. METHODS We followed a consecutive series of 1152 patients with stable angina who had undergone coronary stenting. We measured baseline C-reactive protein levels before stenting with a high-sensitivity assay; 651(More)
