Filter by:To evaluate the short-term and mid-term safety and efficacy of the Catania coronary stent for the treatment of up to two de novo lesions in native coronary arteries.
The use of DES have not diminished the need of improved treatment strategies , especially the treatment of bifurcation lesions still leave much to be clarified. Particularly, for bifurcation lesions where stenting the main branch could result in an obstruction of a vital side branch, many reports have been about using 2 drug-eluting stents. Resulting in less than favorable, target lesion revascularization (TLR) rates, with 10-15% for main branch and 11-40% for side branch. In Japan, the PERFECT multi-center registry evaluated outcomes of single stenting plus kissing balloon technique after Directional Coronary Atherectomy (DCA) removal of tissue plaques. TLR rates for both main branch and side branch were a satisfactory 1.3%. However, the DCA technique is mainly suitable for proximal coronary artery lesions, and takes skilled operators. For the treatment of relatively distal bifurcation lesions, where first POBA is performed, then the lesion is stented, followed by kissing balloon technique to fully expand the side branch, is considered a viable treatment. The Toyohashi Heart Center outcomes from August 2004 for this single stent and kissing ballooning technique, using the sirolimus-eluting stent on bifurcation lesions, achieved a satisfactory 5.2% TLR for both main and side branches, suggesting that using two stents may not be necessarily the ideal treatment. The paclitaxel-eluting stent is expected to become available in Japan from June 2007. This stent's cells can be expanded to a maximum of 3.5mm, which should provide a larger lumen access for side-branch treatment. As such, we developed this study to compare the outcomes of paclitaxel-eluting and sirolimus-eluting stents in bifurcation lesions that require side branch dilatation using the kissing ballooning technique.
Evaluate the impact of systematic nursing orientations in the reduction of predicted cardiovascular risk in patients with coronary artery disease during four nursing visits for a 1-year period and compare to a group of patients submitted to conventional treatment.
Major sporting events may have adverse cardiovascular effects in subjects with coronary heart disease. We also hypothesized that the adverse cardiovascular effects of sporting events are a result of psychobiological processes including stress-induced hemodynamic changes, autonomic dysfunction and parasympathetic withdrawal, and inflammatory and prothrombotic responses, all of which may in turn promote myocardial ischemia.
The purpose of the study is to evaluate the safety and efficacy of dosing with mipomersen for 26 weeks in treating severely hypercholesterolemic patients who are on a maximally tolerated lipid-lowering regimen and who are not on apheresis.
The purpose of this study is to establish the optimal strategy for side branch stenting in coronary bifurcation lesion.
The primary objective is to document the acute and mid-term safety and overall clinical performance of the Endeavor(TM) Zotarolimus Eluting Coronary stent system in a "real world" Chinese patient population requiring stent implantation. To assess the event rate in patient subgroups with specific clinical indications and/or vessel or lesion characteristics.
Chronic total coronary occlusions (CTO) have an especially high risk of angiographic restenosis, and need for new revascularization procedures. Drug-eluting coronary stents (DES) have demonstrated to significantly reduce the risk of restenosis and new revascularization procedures in comparison with bare-metal stents. Most data on the efficacy of DES come from the sirolimus-eluting coronary stent Cypher (Cordis corp.), and paclitaxel-eluting coronary stent Taxus (Boston Sci.), and the Cypher stent is the only DES that has been randomly tested in CTO. Among second-generation DES, everolimus-eluting stent (EES) has shown excellent angiographic and clinical results, but this DES has not been studied in unfavourable scenario (such as CTO). The aim of the CIBELES trial is to demonstrate the hypothesis that EES are equally effective in comparison with sirolimus-eluting stents in the treatment of CTO, in terms of angiographic efficacy considered as in-stent late lumen loss.
Randomized Study To evaluate the safety and effectiveness of the Elixir Medical DESyne Novolimus-Eluting Coronary Stent System with Durable Polymer through the assessment of clinical, angiographic and IVUS endpoints as compared to the concurrently enrolled Medtronic Zotarolimus-Eluting Coronary Stent System in a randomized, single blind study of up to 200 male and female patients. In a Continued Access Registry of up to 100 patients receiving the DESyne Stent clinical-only endpoints will be evaluated. To evaluate the safety and effectiveness of the Elixir Novolimus-Eluting Coronary Stent System with bioabsorbable polymer as compared to the Medtronic Endeavor Zotarolimus-Eluting Coronary Stent System control through clinical and angiographic endpoints.
Heart attacks are usually caused by a blood clot blocking an artery supplying blood to the heart. Current treatments are designed at relieving this blockage as quickly as possible to minimise damage to the heart muscle. However in restoring the supply of blood local damage known as "ischaemia-reperfusion injury" may occur. The aim of this study is to assess how clot forming and clot dissolving pathways are affected during this process, and examine the role of a natural inflammatory hormone, bradykinin. This will help us to understand the mechanism by which ischaemia-reperfusion injury may occur and to devise new treatments for heart attacks.
