OBJECTIVE The incidence of coronary stent thrombosis has reduced with improved techniques and drugs. Nevertheless, clinical trials may not reflect real world practice due to the selective inclusion criteria, regional variations and more complex patients treated in day-to-day practice. We examined the frequency, predisposing factors and outcome of stent thrombosis in unselected patients undergoi...
INTRODUCTION AND OBJECTIVES Percutaneous coronary intervention is recommended in patients with unprotected left main stenosis non suitable for coronary artery bypass graft. Long-term follow-up of those patients remains uncertain. METHODS All patients with de novo unprotected left main stenosis treated with stent implantation were consecutively enrolled. Percutaneous coronary intervention was ...
Percutaneous coronary intervention with intracoronary stenting is the most widely performed procedure for the treatment of symptomatic coronary disease (1). Although drug-eluting stents (DES) have minimized the major limitation of bare-metal stents (BMS), i.e., restenosis, stent thrombosis has emerged as an important late complication of this technology. The primary pathologic substrate underly...
OBJECTIVES Novel stents loaded with an integrin-binding cyclic Arg-Gly-Asp peptide (cRGD) were analyzed for their potential to limit coronary neointima formation and to accelerate endothelialization by attracting endothelial progenitor cells (EPCs). BACKGROUND Re-endothelialization is important for healing after arterial injury. METHODS Effects of cRGD on EPC number, recruitment in flow, an...
This meta-analysis combined the results of randomized clinical trials to compare the efficacy of drug-eluting stents with that of bare metal stents in percutaneous coronary interventions to ascertain which revascularization strategy is most safe and effective. The literature identified 13 published studies, and 8 were included in the main meta-analysis, thus allowing a meta-analysis on 3,860 pa...
BACKGROUND Acute thrombogenicity and re-endothelialization represent clinically relevant end points pertaining to the safety of coronary stents, which have not been compared among biodegradable polymer-based drug-eluting metallic stents and fully bioabsorbable scaffolds to date. METHODS AND RESULTS We investigated comparative outcomes with respect to acute thrombogenicity and re-endothelializ...

The efficacy of drug-eluting stents measured as the late loss, percentage neointimal volume, restenosis, target lesion revascularization and major cardiac events is significantly better than that of bare metal stents. The incidence of thrombosis and aneurysms is similar. Although there is a slight increase in late apposition, this is not followed by an increase in cardiac events. Despite the ar...
