Comparing clinical outcomes for a twelve-month trial of zotarolimus- and everolimus-eluting stents in patients with coronary artery disease: data from the THCRIC registry.

Objectives: New-generation coronary stents including zotarolimus- and everolimus-eluting stents (ZES and EES) have been shown to decrease the risk of restenosis. The purpose of this study was to compare the safety and efficacy of ZES and EES over a 12-month clinical follow up, in routine clinical practice.

Methods: This is an observational study in which 1029 consecutive patients treated with ZES (n = 669) or EES (n = 360) were enrolled.

One-year clinical outcomes of ultra long apollo polymer-based Paclitaxel-eluting stents in patients with complex, long coronary artery lesions.

Background: For all the wealth of research comparing the efficacy of the different types of the drug-eluting stent (DES) such as sirolimus-, paclitaxel-, and zotarolimus-eluting stents, there is still a dearth of data on the different brands of each DES type. We aimed to investigate the one-year clinical outcomes, including major adverse cardiac events (MACE), of the use of the ultra long Apollo paclitaxel-eluting stent in patients with long atherosclerotic coronary artery lesions.

Methods: According to a retrospective review of the Tehran Heart Center Registry of Interventional Cardiology, a single-center nonrandomized computerized data registry in which all adult patients who undergo single or multi-vessel percutaneous coronary intervention (PCI) are enrolled without any specific exclusion criteria, the mixed use of long Apollo paclitaxel-eluting stents and other types of the DES as well as myocardial infarction within forty-eight hours prior to the procedure was excluded.

Percutaneous treatment of spontaneous left main coronary artery dissection extending to the left anterior descending and circumflex arteries possibly triggered by thrombolytic therapy.

Spontaneous coronary artery dissection is a rare cause of myocardial infarction and the role of thrombolytic therapy in this setting is not known. A case of acute ST elevation myocardial infarction is presented, with initial positive response to thrombolytic therapy and subsequent marked worsening of ST elevation due to extensive dissection, possibly triggered by thrombolytic therapy, which was successfully treated with percutaneous coronary intervention.
