Active clinical trials for "Coronary Artery Disease"

The primary objective of this study is to assess whether adding modified-release dipyridamole to aspirin (Asasantin Retard) has measurable effects on markers of platelet function (for example, platelet aggregation) in patients with cardiovascular disease who are known to be resistant to aspirin alone

This trial was designed to examine the efficacy of a brief versus a standard prolonged (18 hours) infusion of eptifibatide in preventing troponin I release following successful coronary stenting.

The ABSORB EXTEND trial is to continue the assessment of the safety and performance of the ABSORB Bioresorbable Vascular Scaffold (BVS) System ABSORB BVS is currently in development at Abbott Vascular.

Surgery for blocked arteries in the heart (coronary artery bypass grafting) can be accomplished using veins from the leg sewn onto the heart to provide an alternate path for blood flow, i.e. 'bypassing' the blockages. These veins themselves can block over time. This may result in part simply from the trauma from the surgery, in other words, by removing the vein from the leg and then sewing it to the heart. Another mechanism may be the abnormal metabolic processes within the body responsible for the plaque build-up of the heart arteries in the first place - this may lead to the blockages of the veins used for bypass. In the present era of heart bypass surgery, this incidence of veins blocking remains high despite advances in blood thinners and cholesterol medications. This study is designed to determine whether two new interventions may potentially reduce the incidence of blockages in the veins used for heart bypass surgery. One is a surgical technique significantly reducing the trauma associated with removing the leg vein prior to use as a bypass graft onto the heart. The second intervention is the use of a nutritional supplement before and after surgery which is composed of fish oils. The study will recruit sufficient patients to provide strong and relevant conclusions regarding both study questions. It will be highly applicable also because it will include approximately 1,550 patients from approximately 50 hospitals across many countries. We believe these techniques will result in significantly less vein blockages in patients one year after heart bypass surgery.

To evaluate the clinical safety, efficacy, and pharmacokinetics (PK) of the Endeavor Resolute Zotorolimus Eluting Coronary Stent System for the treatment of single de novo lesions in native coronary arteries with a reference vessel diameter (RVD) between 2.5 and 3.5 mm in diameter.

Primary intracoronary stent placement after successfully crossing chronic total occlusions (CTO) decreases the high restenosis rate at long-term follow-up compared with conventional balloon angioplasty. Several studies have shown the efficacy of sirolimus-eluting stents in selected groups of patients. Whether sirolimus-eluting stents are superior to bare metal stents in CTO is unknown. In this prospective randomized trial, bare metal stent implantation will be compared with sirolimus-eluting stent implantation for the treatment of chronic total coronary occlusions. A total of 200 patients will be followed up for 6, 12, and 24 months with angiographic follow-up at 6 months. Quantitative coronary analysis will be performed by an independent core laboratory. The primary end point is the binary angiographic restenosis and reocclusion rate at 6 month follow-up.

The purpose of this study is to see if 40 mg of rosuvastatin taken daily will reduce the atherosclerosis (fatty deposits) in your arteries

The objectives of this study are: To show a reduction in the late thrombosis (LT) rate following percutaneous revascularization using current interventional techniques with new stent placement and intravascular radiation therapy (IRT) with a long-term antiplatelet regimen (12 months) compared to the stented patients on short-term antiplatelet regimen (2 months) from the IRT arm of GAMMA I Trial. To show equivalence in the LT rate following percutaneous revascularization using current interventional techniques without new stent placement and IRT with a long-term antiplatelet regimen (6 months) compared to non-stented patients on short term antiplatelet therapy (2 months or less) from a pooling of the IRT arms of the GAMMA I, SCRIPPS, and WRIST Trials.

The main objective of this study is to assess the safety and effectiveness of the CYPHER SELECT™ Sirolimus-eluting Coronary Stent in reducing angiographic in-stent late loss in de novo native coronary lesions as compared to the CYPHER ™ Sirolimus-eluting Coronary Stent.

The purpose of this study is to determine the effect of an antidepressive medication (Escitalopram), started preoperatively and given during 6 months, on 6-month and 1 year post-operative morbidity and mortality after coronary artery bypass grafting
