Filter by:The well established importance of regular administration of antiplatelet drugs stands on firm grounds, as large meta-analyses have shown these therapies to significantly reduce the risk of death. Plavix® (clopidogrel) is widely used following coronary angioplasty, to reduce the risk of periprocedural thrombotic complications, for up to one year. As the current recommendations suggest clopidogrel use for no longer than one year, the drug is normally discontinued within that period. In the limited state of knowledge on antiplatelet drug withdrawal, an early sound of alarm has risen from early thromboembolic complications reported after the interruption of antiplatelet treatment used in prevention of ischemic vascular disease. Although little information is available, discontinuation of thienopyridines has been associated with increased thromboembolic complications, mainly acute stent thrombosis. These complications may signal a platelet sensitization effect to aggregating stimuli by antiplatelet drugs taken chronically. The current study aims to evaluate the impact of clopidogrel discontinuation on platelet function, in order to shed light on underlying mechanisms leading to increased risk of acute thrombo-occlusive events.
The aim of the study is to assess the safety and efficacy of a Paclitaxel-eluting PTCA-balloon in combination with bare-metal stenting for treatment of chronic total occlusions in native coronary arteries with reference diameters between 2.5 mm and 4.0 mm.
How does PET myocardial perfusion imaging involving CT angiography and measurement of coronary flow reserve affect patient care.
This study evaluated and optimized settings for, and evaluated the performance of, AI-700-enhanced echocardiographic imaging on several ultrasound imaging platforms, as well as collected additional safety data for AI-700 in healthy volunteers and stable cardiac patients.
Autologous stem cells may improve myocardial regeneration after intracoronary administration in patients with acute myocardial infarction. The primary hypothesis of this prospective, placebo-controlled, double-blind trial is that the increase of ejection fraction determined by magnetic resonance imaging between baseline and 6 months follow-up is superior in active treated patients compared to patients receiving placebo. The study includes an integrated pilot phase of 40 patients for evaluation of left ventricular ejection fraction determined by cardiac magnetic resonance imaging. Based on the data of this analysis the final sample size will be calculated. The primary endpoint is the improvement in left ventricular ejection fraction with an assumed 2.5% higher improvement in the cell treated population compared to the placebo treated group.
In an observational multi-centre study (HEROS), the effects of starting treatment with rosuvastatin were assessed, on low-density lipoprotein cholesterol (LDL-C) goal achievement, in patients with a dissimilar high-risk profile who had not been treated with cholesterol lowering drugs at least in the past three months. Also set-up costs of rosuvastatin treatment and proportional changes in LDL-C and high-density lipoprotein cholesterol (HDL-C) were studied.
Fifty patients will be enrolled into the study. The purpose of the study is to investigate the relevance of Hct levels in determining need for transfusion during operations employing bypass as well as to test the hypothesis that, while HCt levels may decrease during surgery , red blood cell mass and tissue oxygenation remain fairly constant.
This study will evaluate the potential of RO4607381 to reduce cardiovascular morbidity and mortality in stable coronary heart disease patients with recent Acute Coronary Syndrome (ACS) and evaluate the long term safety profile of the drug. Eligible patients in stable condition will be randomized to receive either RO4607381 600mg po or placebo po, daily, together with a background of standard medication for ACS (including aspirin, antihypertensives and statins). The anticipated time on study treatment is 2+ years, and the target sample size is 15,600 individuals.
The purpose of this study is to determine whether treatment with 40mg of Rosuvastatin for 8 weeks will reduce the number of episodes of myocardial ischaemia suffered in subjects with coronary artery disease.
This study will assess the safety, tolerability and efficacy of RO4607381 in patients with coronary heart disease (CHD) or CHD risk equivalents. Patients will be randomized to receive either RO4607381 600mg po daily or placebo po daily. Endothelial function will be measured by flow mediated dilatation and blood pressure monitoring will be assessed. The anticipated time on study treatment is up to 12 months, and the target sample size is up to 500 individuals.
