We compared the efficacy and safety of drug-eluting stents with that of bare-metal stents in patients who experienced acute ST-segment-elevation myocardial infarction (STEMI) and underwent primary percutaneous coronary intervention. To do this, we performed a meta-analysis of 13 randomized controlled trials in which drug-eluting stents were compared with bare-metal stents in STEMI patients. The...
Drug-eluting stents reduce the occurrence of in-stent restenosis and the need for subsequent target vessel revascularization compared with bare-metal stents. However, the safety of drug-eluting stents has been called into question because of an apparent increase in late stent thrombosis, a frequently fatal event. A substantial body of research has focused on determining the magnitude of these c...
In-stent restenosis is the major drawback of percutaneous coronary interventions, occurring in 10-40% of the patients. Recently, new stents have emerged which are loaded with anti-inflammatory, anti-migratory, anti-proliferative or pro-healing drugs. These drugs are supposed to inhibit inflammation and neointimal growth and subsequently in-stent restenosis. In this review article the results of...
BACKGROUND Data on clinical outcomes among patients treated with the zotarolimus-eluting Endeavor™ stent versus the sirolimus-eluting Cypher™ stent favor the sirolimus-eluting stent. However, a separate comparison of clinical outcome among patients treated for multiple lesions with these stents is lacking. We performed this comparison within the SORT OUT III trial data set. METHODS Among 2332...
The safety and efficacy of coronary stents, utilized for treatment of ischemic heart disease, have been evaluated extensively. In comparison with bare-metal stents, first-generation drug-eluting stents more than halved the need for target lesion revascularization, but long-term safety has been questioned, as the first-generation drug-eluting stents seem to be associated with a small, but increa...
OBJECTIVES We designed a randomized trial exploiting optical coherence tomography (OCT) to assess coverage and apposition of overlapping bare-metal stents (BMS) and drug-eluting stents (DES) in human coronary arteries. BACKGROUND Overlapping DES impair healing in animals. Optical coherence tomography allows accurate in vivo assessment of stent strut coverage and apposition. METHODS Seventy-...
OBJECTIVES This study sought to evaluate the associations between homeostatic indexes of insulin resistance (HOMA-IR) and post-procedural myocardial injury and clinical outcome after a percutaneous coronary intervention (PCI) with a drug-eluting stent. BACKGROUND Insulin resistance increases the risk of cardiovascular events. However, the association between insulin resistance and clinical ou...
First generation drug-eluting stents have considerably reduced in-stent restenosis and broadened the applications of percutaneous coronary interventions for the treatment of coronary artery disease. The polymer is an integral part of drug-eluting stents in that, it controls the release of an antiproliferative drug. The main safety concern of first generation drug-eluting stents with permanent p...
BACKGROUND Several studies have compared the treatment effects of coronary stenting and coronary-artery bypass grafting (CABG). However, there are limited data regarding the long-term outcomes of these two interventions for patients with unprotected left main coronary artery disease. METHODS We evaluated 1102 patients with unprotected left main coronary artery disease who underwent stent impl...
BACKGROUND Drug-eluting stents improved the outcome after percutaneous coronary intervention (PCI), however, there may be significant differences in their safety and efficacy. AIM To compare the in-hospital and mid-term clinical outcomes of stenting with sirolimus-eluting stents (SES) versus paclitaxel-eluting stents (PES) for the treatment of coronary artery lesions in our routine practice. ...
