Filter by:An open-label, prospective, single-arm study is designed to evaluate safety, clinical and technical efficacy of the CorPath 200 System in delivery and manipulation of the coronary guide wires and balloon/stent systems for use in robotically-assisted, percutaneous coronary intervention (PCI) procedures.
The purpose of this study is to compare coronary endothelium function in patients with a zotarolimus-eluting versus a sirolimus-eluting or a everolimus-eluting stents with optical coherence tomography, vasoconstriction in response to acetylcholine, and coronary biomarker level.
The use of coronary angiography to investigate patients at risk of coronary artery narrowings has become universal. In most cases, this investigation leads to a successful treatment plan with revascularisation recommended where appropriate. However in a substantial number of patients, the images taken of the coronary arteries can lead to diagnostic uncertainty. Increasingly, doctors are using devices called pressure wires to clarify the significance of coronary artery narrowings in order to tailor patient treatment on an individual basis. The Radi pressure wire is well recognised as a reliable tool in assessing whether a narrowing is significant in functional terms, that is, does it significantly restrict blood flow to the heart muscle.It consists of a fine wire that is fed into individual major coronary arteries to measure pressure within the vessel itself. In conjunction with the images taken of the arteries, it is very useful in deciding how best to treat patients. This study enrolls volunteers who are being investigated for stable cardiac-sounding chest pain and are undergoing a coronary angiogram. It will investigate whether the extra information gained from pressure wire assessment will change patients' treatment plan.
The purpose of this study is to evaluate the safety and effectiveness of the peripheral IV continuous infusion without the insertion of central venous vascular access method in the achievement of steady-state maximal coronary hyperemia compared with the central IV continuous infusion method.
The purpose of this study is to evaluate the effect of high dose clopidogrel as the antiplatelet therapy on inhibition of platelet aggregation in Japanese patients scheduled for percutaneous coronary intervention due to ischemic heart disease.
EDUCATE is a prospective, multi-center study designed to collect real-world safety and clinical outcomes in subjects receiving one or more Endeavor Zotarolimus-Eluting Stents and either clopidogrel and aspirin or prasugrel and aspirin as part of a dual antiplatelet therapy (DAPT) drug regimen.
The aim of this prospective, randomized study is to compare the efficacy and safety of biodegradable polymer based limus-eluting stents (BPDES) with permanent polymer based everolimus eluting stents (PPDES).
The purpose of this study is to assess the effects of Ezetimibe on coronary plaque volume in patients with acute coronary syndrome.
The investigators evaluated predictive values of myocardial fatty acid metabolism and insulin resistance for cardiac death of hemodialysis patients with normal coronary arteries.
This study is designed to characterize the early effects of ApoA-I synthesis with RVX000222 on coronary atherosclerotic disease when administered to patients with coronary artery disease and have a low HDL-C level, as assessed by Intravascular Ultrasound (IVUS) in addition to standard background therapy.
