Active clinical trials for "Coronary Artery Disease"

The duration of dual antiplatelet treatment (i.e. asprin and clopidogrel) after drug-eluting stent implantation is highly debated. This study will evaluate the value of extending such treatment up to 2 years after the procedure as compared to conventional treatment according to our national health institute guidelines (i.e. minimum 1 month after bare metal stent and 6 months after drug-eluting stent) on the composite endpoint of death, MI or stroke.

This study is being done to see if the blood pressure lowering effect of an approved drug nebivolol is comparable to that of another approved drug carvedilol for the treatment of hypertension in patients who have coronary artery disease.

The purpose of this study is to see how Ticagrelor, a new oral reversible anti-platelet medication, affects platelets. Anti-platelet agents are medications that block the formation of blood clots by preventing the clumping of platelets. Blood clots prevent us from bleeding, but when they form inside the arteries their formation is linked to a risk of medical problems such as heart attack and stroke. This study investigated the effect of Ticagrelor on inhibition of platelet aggregation compared with clopidogrel in patients previously identified as non-responsive to clopidogrel.

Patients with diabetes are more likely to develop furring of their coronary arteries and present with angina and heart attacks. Furthermore, after such an event, they have poorer outcomes (higher rates of death) and survivors are more likely to have recurring symptoms. Using a novel "clotting chamber" the investigators have shown that patients with diabetes are more likely to develop blood clots. This study will look at the role of different blood thinning medications in patients with diabetes. If successful, the investigators will provide evidence to conduct large clinical studies to look at the role of additional blood thinning medication in reducing heart attacks and strokes in patients with diabetes.

The objective of the study is to assess the safety and effectiveness of the Resolute Zotarolimus-Eluting Coronary Stent System for the treatment of de novo lesions in native coronary arteries with a reference vessel diameter (RVD) of 2.25 mm to 4.2 mm.

The purpose of this study is to evaluate two approaches to red blood cell transfusion in anemic patients with acute coronary syndrome.

Background: Retrospective analyses of long-term BASKET findings identified patients with large drug-eluting stents (DES) (>2.5mm Stents) as patients at risk for late cardiac death/nonfatal myocardial infarction. In view of new DES with absorbable polymers and new bare metal stents BMS) with thin struts and biocompatible polymers, BP-II will be launched to test their comparative clinical safety up to 12 years if treated with an aspirin/prasugrel combination, since prasugrel halved stent thrombosis rates compared to clopidogrel in a large ACS trial. The primary objective is to demonstrate non-inferiority of the Nobori DES stent compared to the Xience Prime DES stent on safety and e cacy in patients requiring stents >=3.0mm in diameter on the background of contemporary dual antiplatelet therapy (DAPT) with prasugrel and aspirin Set-up: Multicenter open-label randomized trial. Patient inclusion: Unselected series of patients in need of large (>3mm) stents only in native vessels irrespective of clinical indication. Patient exclusion: In-stent restenosis, Left-main disease, cardiogenic shock, planned surgery <12months, increased bleeding risk, no compliance expected, History of stroke or transient ischemic attack (TIA). Randomization: By centre using sealed envelopes 1:1:1: Nobori:Xience Prime:Prokinetik-stent.

This is a prospective, randomized study conducted in patients undergoing coronary revascularization procedures (PCI) through angioplasty. All patients who meet the eligibility criteria will be randomized to receive, before the procedure, an oral aspirin reload (325 mg) and to be re-evaluated at 60 minutes, 120 minutes, 6 hours, 48 hours, 5 and 30 day, 3 and 6 months.

The purpose of this study is to establish the safety and effectiveness of coronary stenting with the Zotarolimus-Eluting stent compared to the Sirolimus-Eluting stent in the treatment of de novo coronary stenosis in patients with diabetic patients.

This randomized study is a multi-center, randomized, study to compare the efficacy of biolimus A9-eluting stent (Nobori) vs. everolimus-eluting stent (Promus Element) for long coronary lesions.
