Filter by:This trial will compare the long term safety and effectiveness of the V Flex Plus PTX Drug Eluting coronary stent with conventional treatment for in-stent restenosis for coronary arteries.
ELUTES is a European multicenter, randomized, controlled, triple-blinded study designed to evaluate the ability of the Paclitaxel Eluting V-Flex Plus coronary stent to reduce restenosis in the coronary artery.
Assesses physician compliance with paper-based and electronic guidelines, reminders, and alerts for outpatient settings. Target areas for the reminders and alerts are disease management, medication management, and interpretation of abnormal test results.
The Transesophageal Echocardiography (TEE) Surgical Treatment of Ischemic Heart Failure (STICH) ancillary study will define the mechanism(s) of functional mitral regurgitation (MR) by TEE in patients with ischemic cardiomyopathy, and the impact of therapy (medical, coronary artery bypass grafting [CABG], or CABG plus surgical ventricular restoration [SVR]) on mechanism and severity of MR. Severity of the effect of functional MR on clinical outcomes will also be examined. The TEE STICH study will address four specific aims that will focus on defining the following: 1) the mechanism(s) of functional MR in ischemic cardiomyopathy; 2) the effect of therapy on the mechanism and severity of functional MR; 3) myocardial viability on functional MR and its response to treatment; and 4) the effect of MR on prognosis in ischemic cardiomyopathy.
After successful percutaneous coronary intervention (PCI) for acute ST-segment elevation myocardial infarction, 60 patients were randomly assigned to either a control group (n=30) that received optimum postinfarction medical treatment, or a bone-marrow-cell group (n=30) that received optimum medical treatment and intracoronary transfer of autologous bone-marrow cells 4·8 days (SD 1·3) after PCI. Primary endpoint was global left-ventricular ejection fraction (LVEF) change from baseline to 6 months’ follow-up, as determined by cardiac MRI. Image analyses were done by two investigators blinded for treatment assignment. Analysis was per protocol. Global LVEF at baseline (determined 3·5 days [SD 1·5] after PCI) was 51·3 (9·3%) in controls and 50·0 (10·0%) in the bone-marrow cell group (p=0·59). After 6 months, mean global LVEF had increased by 0·7 percentage points in the control group and 6·7 percentage points in the bone-marrow-cell group (P=0·0026). Transfer of bone-marrow cells enhanced left-ventricular systolic function primarily in myocardial segments adjacent to the infarcted area. Cell transfer did not increase the risk of adverse clinical events, in-stent restenosis, or proarrhythmic effects.
In the ASCET study, 1000 patients with documented coronary heart disease will be randomized to either continued treatment with aspirin 160 mg/d or change to clopidogrel 75mg/d. Clinical endpoints will be recorded for at least 2 years and related to the initial aspirin response, assessed by the PFA-100® method, to investigate whether aspirin non-responders have higher composite event rate than responders or whether Clopidogrel treatment in patients non-responsive to aspirin will reduce their risk of future clinical events. The clinical events are the composite of unstable angina, myocardial infarction, stroke or death.
The purpose of this study is to determine whether the intervention for newly diagnosed abnormal glucose tolerance after coronary stenting will improve the long-term clinical outcome.
The aim is to evaluate the effect of exercise training upon endothelial function in the mammary artery of patients who are scheduled for CABG, as well as study the functional properties of single cells isolated from a small biopsy of the left ventricle obtained during surgery.
The purpose of this study is to assess the equivalence in safety and efficacy of the Endeavor Drug Eluting Coronary Stent System when compared to the Taxus Paclitaxel-Eluting Coronary Stent System for the treatment of single de novo lesions in native coronary arteries with a reference vessel diameter (RVD) of 2.5-3.5 mm.
To demonstrate the equivalency in in-segment late lumen loss at 8 months between the Endeavor Drug Eluting Coronary Stent System coated with ABT-578 (10 micrograms/mm) and the Cypher Sirolimus-Eluting Coronary Stent System for the treatment of single de novo lesions in native coronary arteries 2.5-3.5 mm in diameter.
