Active clinical trials for "Coronary Artery Disease"

The purpose of this study is to evaluate the safety and performance of the CYPHER SELECT™+ Sirolimus-eluting Stent (SES) in Asian diabetic patients.

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

The purpose of the study is to assess the safety and efficacy of hybrid revascularization in comparison with coronary artery bypass grafting among patients with multivessel coronary artery disease.

All patients who have received GENOUS stent implantation at Queen Mary Hospital for treatment of ischemic heart disease are eligible for this study. Those with clinical indications to undergo restudy coronary angiogram or staged procedure PCI will be primarily recruited into this study. Optical coherence tomography (OCT) will be performed early after stent implantation to evaluate vascular healing response and neointimal coverage.

Diabetes mellitus (DM) is an important risk factor in the development of cardiovascular disease, and people with type 2 diabetes have a two- to four-fold increased risk for cardiovascular morbidity and mortality. Physical activity is a well established therapeutic modality for type 2 diabetes. In patients with coronary artery disease (CAD), several clinical trials have shown reduced mortality and reduced progression of atherosclerosis with lifestyle intervention including physical activity. But few studies have investigated the effect of physical training in patients suffering from both diseases. The aim of this study is to investigate the effect of one year of organized physical exercise in patients with both coronary heart disease and type 2 diabetes on glucometabolic state and progression of atherosclerosis. The project is a randomized, controlled, open study on physical exercise. 136 patients will be randomized at inclusion to a physical exercise group or a control group, the latter with "normal" follow-up and not discouraged form physical activity. The intervention period will be 12 months, and the physical training program will be developed and conducted in collaboration with Norwegian School of Sport Sciences. The inclusion of patients started summer 2010, the exercise program begins in September 2010 and the practical issues of the study is planned to end during spring 2012. The main hypothesis is that physical exercise improves the glucometabolic state and reduces progression of atherosclerosis in patients with coronary heart disease and type 2 diabetes, and secondary that physical exercise induces favourable changes in cardiovascular risk factors, use of medication, and co-morbidity associated with diabetes.

This study is being conducted to determine if smoking will influence the platelet aggregation inhibition ability of clopidogrel and prasugrel. It will also determine if smoking has any effect on the plasma concentrations of the active metabolite of prasugrel and the active and inactive metabolites of clopidogrel. The primary hypothesis is that smoking status will influence the antiplatelet effects and active metabolite concentrations of clopidogrel but will have no impact on prasugrel's antiplatelet effects or active metabolite concentrations.

The DESSOLVE I clinical trial is to assess the safety and performance of the sirolimus-eluting MiStent SES.

Comparison of the cardioprotective effects and safety of two cardioplegic solutions (solutions used during a cardiac arrest in the heart surgery) in patients undergoing cardiopulmonary bypass for coronary artery bypass surgery.

The purpose of this study is to examine the effectiveness of a Psychodynamic Motivation and Training Program (PMT) for the improvement of physical fitness in patients with stable coronary heart disease as compared to advice in exercise training or treatment as usual.

Coronary artery stents have improved the safety and efficacy of percutaneous coronary intervention for coronary artery disease. Drug-eluting stents have been shown to decrease neointimal hyperplasia and to reduce the rate of restenosis and target-lesion revascularization as compared to bare-metal stents. Drug-eluting stents consist of a metallic platform and a therapeutic substance that is usually released from a polymer matrix. A previous study utilizing a bioresorbable polymer has demonstrated a favorable safety and efficacy profile in a large-scale clinical trial as compared to a first-generation druf-eluting stent (LEADERS trial). The objective of the study is to compare the safety and efficacy of a sirolimus-eluting stent with a biodegradable polymer with an everolimus-eluting stent with a durable polymer in a prospective multicenter randomized controlled non-inferiority trial in patients undergoing percutaneous coronary intervention in routine clinical practice.
