Active clinical trials for "Coronary Artery Disease"

How does PET myocardial perfusion imaging involving CT angiography and measurement of coronary flow reserve affect patient care.

The purpose of this study is to determine whether exposure to diesel exhaust (air pollution) has a functional impact on patients with stable angina pectoris.

The aim of this study is to evaluate the different performance of arterial and venous graft with intra-aortic balloon pump support following coronary artery bypass.

The objective of this study is to evaluate effectiveness and safety of everolimus-eluting stents (XIENCE, Abbott) in the "real world" daily practice as compared with first-generation drug-eluting stents (sirolimus-eluting stents).

This study is a multicenter, open label, prospective, single arm trial Single arm group; following angiography, eligible patients with unprotected LMCA stenosis >50% by visual estimation, which is equally treatable by the both treatment strategy (EES stenting or CABG), will be treated with EES

The objective of this study is to evaluate effectiveness and safety of Nobori stent in the "real world" daily practice as compared with first-generation drug-eluting stents (sirolimus- or paclitaxel-eluting stents).

Stents are devices utilized to treat cholesterol blockages of the coronary (heart) arteries. The introduction of drug-eluting (coated) stents into clinical practice is regarded as a revolutionary breaktrhough, as it has reduced the incidence of re-narrowing of the arteries after percutaneous coronary interventions are performed. There has been, however, concerns of increased risk for clot formation in the heart arteries of patients treated with drug-eluting stents. Therefore, in order to lower the risk of clot formation, it is recommended that patients receiving these types of stents, be treated with dual antiplatelet therapy (blood thinning medication) for one year. The effect of this strategy, however, on clot formation and bleeding complications when utilizing "newer generation" stents, such as the Xience: Everolimus-eluting Stent, have not been well described. Therefore, the aim of this registry study is to evaluate the risk of adverse cardiovascular events, including mortality, non-fatal myocardial infarction, stent thrombosis, hemorrhagic stroke, and severe bleeding in relation to the timing and discontinuation of dual antiplatelet therapy in patients treated with Xience drug-eluting stents, and compare it to patients that do not discontinue dual antiplatelet therapy.

The effects of race/ethnicity on platelet function and response to antiplatelet agents will be assessed using healthy participants and coronary heart disease patients from at least 5 racial/ethnic groups.

This is a Scripps pilot study on the effect of high clopidogrel maintenance dosing and its relationship to cytochrome P450 2C19 polymorphism status [STSI/CTSA].

Prospective, multicenter, randomized (two-arm 1:1), non-inferiority clinical evaluation comparing 2 regimes of dual antiplatelet therapy (DAPT) with aspirin + clopidogrel following percutaneous coronary intervention (PCI) with Endeavor Zotarolimus eluting stent (ZES) to evaluate the impact of different regimes of DAPT on clinical outcomes in minimally selected patients from the "real-world" clinical practice receiving the Endeavor ZES for the treatment of coronary artery lesions. Patients undergoing percutaneous treatment with the Endeavor ZES will be randomized in a 1:1 ratio to 2 regimens of DAPT including oral clopidogrel 75mg/day for 3 months versus 12 months.
