Filter by:The purpose of this study is to evaluate the safety and efficacy of K-604 for the treatment of atherosclerosis.
Rationale: Statins form a class of drugs that is widely prescribed for hypercholesterolaemia, specifically to reduce the risk on atherosclerosis by lowering LDL-cholesterol. Next to the effect for which the drug was originally developed, it became obvious that statins have several other beneficial effects. Such pleiotropic effects include the activation of ecto-5'-nucleotidase which can increase endogenous adenosine production (by dephosphorylation adenosine monophosphate into adenosine) and subsequently cause vasodilation. A recent study of Meijer et al (not yet published) showed that rosuvastatin significantly augments vasodilation after a brief period of ischemia (post occlusive reactive hyperaemia). However, it is not yet verified whether this increase in post occlusive reactive hyperaemia is truly caused by a rise of extracellular adenosine and subsequent adenosine receptor stimulation. In this study, the mechanism by which rosuvastatin augments post occlusive reactive hyperaemia will be investigated by blocking adenosine receptors with caffeine, a competitive A1 and A2 adenosine receptor antagonist. Caffeine is a substance that can be safely used in normal concentrations to block the adenosine receptor. Hypothesis: The augmenting effect of rosuvastatin on PORH is caused by an increase of extracellular adenosine formation and this effect can be diminished by blocking the adenosine receptor using caffeine. Objective: To study the influence of caffeine on post occlusive reactive hyperaemia before and after 7 days treatment with rosuvastatin. Study design: Open label cross-over design Study population: Healthy volunteers, 18-50 years of age Intervention: Eight volunteers will receive a 7 day treatment with rosuvastatin 20 mg daily before and after rosuvastatin treatment caffeine will be administrated intra-arterially. Main study parameters/endpoints: Forearm blood flow (FBF) will be measured as an indicator for post occlusive reactive hyperaemia (PORH).
The purpose of this study is to validate novel assays for serum biomarkers of lipid metabolism (PCSK9 and LDL receptor) and to obtain information about how these biomarkers differ in subjects with normal or high cholesterol levels
The purpose of this research is to determine the relationship between novel blood tests for heart function (including hormones and heart enzymes measured in the blood), and assess for kidney damage before and after angiography (cardiac catheterization). We hypothesize that these novel tests will enable us to predict possible complications of catheterization immediately after the procedure.
The primary purpose of this study is to evaluate the safety and tolerability of multiple oral doses of BMS-779788 in healthy subjects
To compare to different approaches in whole-body magnetic resonance angiography of patients suffering peripheral arterial disease. Our hypothesis is that use of a new protocol improves the diagnostic quality of the WB-MRA procedure.
Compile acute (30-day) clinical outcomes data and 9-month angiographic and intravascular ultrasound (IVUS) data for the PROMUS Elementâ„¢ Everolimus- Eluting Coronary Stent System in the treatment of patients with a single de novo atherosclerotic lesion
Randomized, control, open label, multicentre clinical study. The patient who are in accordance with subject inclusion and exclusion criteria will be randomized to A group: Routine treatment B group: Routine treatment+ Cilostazol; C group : Routine treatment + Probucol; D group: Routine treatment+ Cilostazol+ Probucol .
1. To evaluate the efficacy of Cilostazol and Probucol alone and in combination on atherosclerosis related biomarker 2. To evaluate the safety of Cilostazol and Probucol alone and in combination on atherosclerosis related biomarker
To see if restenosis rates of superficial femoral artery atherosclerosis with percutaneous techniques can be improved using paclitaxel.
