Active clinical trials for "Coronary Artery Disease"

The DTS.DE registry is an initiative for the collection of high quality process and historical data of implantations with the COMBO Dual Therapy Stent in Germany. DTS.DE was designed as a national, non- randomized, prospective, multicenter registry without a comparison group. The responsible Steering Committee is of the opinion that the Combo stent qualifies for further documentation of treatment results in the form of a German registry, based the CE certification of the COMBO Dual Therapy stent in 2013 and its clinical and scientific investigation in the context of the REMEDEE study program, as well as company independent externally initiated studies with the COMBO Dual Therapy Stent. It is expected that by mid- 2015, at least 1,000 patients will be enrolled and documented in the DTS.DE registry with the COMBO Dual Therapy Stent. A clinical follow-up is performed after 6 weeks and 12 months.

The number and function of circulating endothelial progenitor cells (EPCs) are inversely associated with coronary risk factors and atherosclerotic diseases such as coronary artery disease (CAD) and cardiovascular high risk. This double-blind, randomized, placebo-controlled trial to evaluate the effects of cilostazol on human early EPCs and endothelial function as well as the potential mechanisms of action in patients with CAD and cardiovascular high risk.

The hypothesis is that home based clinical rehabilitation (CR) is less expensive than hospital based CR with similar clinical effectiveness. The investigators will compare the results of two forms of CR on direct and indirect healthcare costs effectiveness on mortality, morbidity, modifiable risk factors control, functional capacity measured by exercise testing, health related quality of life and satisfaction rate cost/effectiveness analysis

Randomized trials have demonstrated an excellent safety and efficacy profile for the chromium everolimus-eluting stent. The platinum chromium everolimus-eluting sten (PtCr-EES) uses the identical antiproliferative agent and polymer but with a novel platinum chromium scaffold designed for enhanced deliverability, vessel conformability, side-branch access, radiopacity, radial strength, and fracture resistance. However, the efficacy of the PtCr-EES for complex coronary artery diseases subsets such as chronic total occlusion, bifurcation lesion, left main trunk disease, and small vessel diseases is still unknown.

The superiority of a percutaneous coronary intervention (PCI) by one stent over another in terms of clinical outcome is usually documented in large randomized controlled trials (RCT). Although generated from selected study populations these data form the basis for evidence based practice (EBP) in the entire population of patients considered for coronary intervention. An inherent limitation of this approach is that study populations differ significantly from all comers in terms of patient characteristics and prognosis undermining the foundation for extrapolation of trial results to all comers. Furthermore, other trials are based on a "one-fits-all" concept, while the benefits of an "individual-tailored" approach that might be superior, is not investigated. The Purpose of the current study is to Compare clinical outcome between several CE marked drug eluting stents Compare clinical outcome between several CE marked bare metal stents Compare clinical outcome in all comers with that of the selected study population of RCT's Evolve methods to compare clinical outcomes between the generalized "one-fits-all" versus the individualized or "individual-tailored" stent selection approaches The Method employed is All comer PCI registry - single centre Randomisation of all eligible patients within the registry to one of several study stent Quality assurance in non-randomized population within the registry by periodical alternating the institutional standard stent Continuous follow up of all patients included the registry by means of systematic event detection and classification by an independent safety and end point committee Assessment of effects on quality of life by heart and health questionnaires Outcome Measures Primary endpoints: Composite of cardiac death, acute myocardial infraction and target vessel revascularisation Stent thrombosis A specifically developed Treatment Failure Rate classification Secondary outcome measures include each of the above, target lesion revascularisation and total death analyzed in a hierarchical fashion at 2, 3, 4 and 5 years. Tertiary outcome measure is self reported quality of life based on health questionnaires on general health and cardiac symptoms. Power Calculations An event rate of 20% within 5 years, a relative difference of 25% (an absolute difference of 5%), P< 5%, Power > 80% => 900 patients in each of two treatment arms. Prespecified Analysis include The MACE rates between stent types The Stent thrombosis rates between stent types The Treatment failure rates between stent types The randomized population versus non-randomized population The individualized versus the generalized Population QOL between stent types

This study evaluates the safety and effectiveness of the Momo Cobalt Chromium stent system for the treatment of single de novo lesions in a native coronary artery. The stent is coated with diamond-like carbon to decrease the risk of acute and late stent thrombosis, to increase the resistance towards corrosion and to significantly improve endothelialisation through the inhibition of elution of metallic ions.

A single blind, multi-center, randomized study is preformed to compare NOYA CoCr biodegradable coating sirolimus-eluting stents with Firebird2 drug-eluting stents from MicroPort Medical (Shanghai) Co., Ltd. to evaluate the safety and efficacy of NOYA CoCr biodegradable coating sirolimus-eluting stents in treating coronary artery lesions.

To investigate the mid- and long-term effect of Enhanced External Counterpulsation combined with guideline-driven standard treatment on patients documented with and/or at high risk of coronary artery disease.

The study aims to assess the effectiveness of dual antiplatelet therapy, aspirin alone versus steeply discontinued clopidogrel plus aspirin in preventing clinical MACE events.Our subject is beyond a 12-month period patients receiving sirolimus drug-eluting stent implantation.

Sirolimus-eluting stent (SES) has been world-widely used in clinical practice in treating patients with coronary artery disease (CAD). The efficacy and safety of Excel SES (JW Medical, Shandong, China, MA) with biodegradable polymer has been proved by several clinical trials. Here the investigators design a prospective, multicenter, randomized clinical study in purpose of identifying the non-inferiority in the efficacy and safety in treating CAD patients by Firebird 2 SES (Microport, Shanghai) with durable polymer, comparing with Excel SES.
