Platelet-dependent Thrombosis: a Placebo-controlled Trial of Antiplatelet Therapy (Clopidogrel)...
Type 2 Diabetes MellitusCoronary Artery DiseasePatients 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.
Research on Nicorandil Treatment of Patients Diagnosed as CHD (Coronary Heart Disease) With Stable...
Stable AnginaCoronary DiseaseThis study of 402 cases of stable angina subjects who were diagnosed as Coronary Heart Disease (CHD) is a randomized, blank controlled, multi-center clinical study. Subjects who are taking standard treatment with stable symptoms will receive a 24-hour ambulatory electrocardiogram (ECG) (Holter) examination. They will be randomly divided into two groups. The nicorandil group will receive nicorandil 5 milligram (mg) (3 times a day = tid) on top of the standard treatment for 12 weeks, while the control group will stay on standard treatment. Nitrates and beta blockers need to be maintained on a stable dose. Other drugs that do not affect the primary endpoint may be adjusted per investigators decision.
Evaluation of the Safety and Effectiveness of the CorPath 200 System in Percutaneous Coronary Interventions...
Coronary Artery DiseaseCoronary Disease6 moreThe objective of this study is to evaluate the safety and effectiveness of the clinical and technical performance of the CorPath® 200 System in the delivery and manipulation of coronary guidewires and stent/balloon systems for use in percutaneous coronary interventions (PCI).
Exercise Training Adherence After Cardiac Rehabilitation in Coronary Heart Disease Patients
Coronary DiseaseIt is known that organized cardiac rehabilitation is effective in improving exercise capacity in coronary heart disease patients. Less is known about the long-term results after cardiac rehabilitation. Earlier studies have shown that many patients quit exercising when no longer attending formal rehabilitation. The investigators wish to investigate the effect of a maintenance program after ending a rehabilitation program, and to compare this to usual care. The investigators hypothesis is that the maintenance program will result in higher exercise capacity and more physical activity compared to usual care.
Aspirin Reload Before Percutaneous Coronary Intervention: Reperfusion Indexes Evaluation.
Coronary ArteriosclerosisThis 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.
Effect of Probucol and/or Cilostazol on Mean IMT in Patients With Coronary Heart dIsease
HyperlipidemiasThe purpose of this study is to evaluate the additional effect of probucol or concomitant administration of cilostazol and probucol on mean carotid artery intima-media thickness (mean IMT) at year 1, 2, and 3.
P E P C A D II, The Paclitaxel-Eluting PTCA-Balloon Catheter in Coronary Artery Disease to Treat...
In-Stent RestenosisThe aim of the study is to assess the safety and efficacy of the Paclitaxel-eluting PTCA-balloon in the treatment of in-stent restenoses in native coronary arteries with reference diameters between 2.5 mm and 3.5 mm and ≤ 22 mm in length for procedural success and preservation of vessel patency in comparison to the Paclitaxel-eluting Taxus™ stent.
A Long Term Extension of Study NC19453 Evaluating Safety and Efficacy of RO4607381
Coronary Heart DiseaseThis 2 arm study will assess the long term safety and efficacy of RO4607381 in patients with coronary heart disease or a coronary heart disease (CHD) risk equivalent who have completed study NC19453. Patients eligible to participate in the extension study will continue on the treatment they were originally assigned to ie RO4607381 (900mg po) or placebo daily, with concomitant daily atorvastatin (10 to 80mg po). The anticipated time on study treatment is 6 months post study NC19453, and the target sample size is approximately 100 individuals.
TAXUS PERSEUS Small Vessel
Coronary Artery DiseaseThe purpose of the TAXUS PERSEUS Small Vessel trial is to evaluate the safety and efficacy of the next-generation Boston Scientific TAXUS paclitaxel-eluting coronary stent system (TAXUS® ElementTM) for the treatment of de novo atherosclerotic lesions of up to 20 mm in length in native coronary arteries of ≥ 2.25 mm to < 2.75 mm diameter.
Effects of Atorvastatin Versus Pravastatin on Platelet Inhibition by Clopidogrel
Ischemic Heart DiseaseAcute Coronary SyndromesClopidogrel and statins are frequently coadministered in patients with ischemic heart diseases. Recent reports suggested that clopidogrel's effectiveness in inhibiting adenosine diphosphate (ADP)-induced platelets aggregation is attenuated by co-administration of certain statins. The objective of the present study is to define which kind of statins might interfere with the antiaggregation property of clopidogrel in patients with acute coronary Syndrome after percutaneous coronary intervention (PCI). In this prospective randomized study, all patients in test group will receive clopidogrel plus atorvastatin, and all patients in control group will receive clopidogrel plus pravastatin. All patients will be followed up for one year. The primary endpoints include death, non fatal AMI, urgent revascularization. The secondary endpoints include hemorrhage events and subacute thrombosis events at 1 year.
