Active clinical trials for "Coronary Artery Disease"

Until today it was not possible to reliably assess the function of a new bypass, i.e., to measure myocardial perfusion. Measuring intramyocardial blood flow directly after revascularisation would greatly improve the assessment of graft function. With transthoracic contrast echocardiography, myocardial perfusion can be reliably assessed, as it has been shown in numerous studies. In the first part of the study the investigators will clarify methodological aspects of contrast echocardiography. In the second part they will analyze the validity of contrast TEE in the operating room.

The purpose of this study is to compare levels of clot formation (platelet aggregation), markers of heart muscle damage, and inflammation in two groups undergoing percutaneous coronary stent implantation. The first group will be on a regimen of high-dose clopidogrel used in combination with bivalirudin plus eptifibatide, and the second group will be on a regimen of high-dose clopidogrel with bivalirudin alone. Clinical outcomes will be determined up to one year after enrollment.

The MyoCell™ implantation using the MyoCath™ delivery catheter system may have the potential to add a new dimension to the management of post-infarct deterioration of cardiac function in subjects with congestive heart failure. Based on pre-clinical studies, implantation of autologous skeletal myoblasts may lead to replacement of non-functioning myocardial scar with functioning muscle and improvement in myocardial performance. Preliminary data in human subjects suggest skeletal myoblast implantation at the time of CABG may lead to the same effects. In principal, myoblast implantation by catheter delivery may offer the same therapeutic benefit. The present clinical study is to be conducted primarily to evaluate the safety of MyoCell™ implantation using the MyoCath™ delivery system and secondarily to evaluate the effect on regional myocardial function post treatment.

The investigators hypothesize that reducing the duration of clopidogrel therapy from 6 months to 6 weeks after DES implantation is associated with improved clinical outcomes in patients on ASA and an oral anticoagulant.

Prospective, multi-center, randomized, controlled (patients as their own control) trial on an external mesh device (eSVS™, Kips Bay Medical) supporting saphenous vein grafts for coronary bypass graft surgery in patients with multi-vessel coronary heart disease.

The "one-stop" hybrid coronary revascularization combines minimally invasive direct coronary artery bypass (MIDCAB) and PCI to be performed in the hybrid operating suite, an enhanced operating room equipped with radiographic capability. This study is to compare 1-year clinical outcomes of "one-stop" hybrid coronary revascularization with off-pump coronary artery bypass (OPCAB) in selected patients with multivessel coronary artery disease.

The aim of this study is to evaluate if the intracoronary infusion of autologous bone-marrow derived CD133+ endothelial precursor cells is able to promote neovascularization and to improve myocardial perfusion and contractility in patients with refractory coronary heart disease, characterized by poor response to standard coronary interventions, severe impairment of the quality of life, and poor prognosis.

The purpose of this prospective, non-randomized, single-arm feasibility study is to evaluate safety and feasibility of the iCoapsys System in patients with functional mitral valve insufficiency caused by annular dilation and/or papillary muscle displacement.

The purpose of this study is to evaluate the safety and efficacy of the eucaLimus Sirolimus Eluting stent system in patients with de novo coronary lesions.

Compared with conventional treatment of the coronary heart disease,the aim of the research is to find out if the addition of Yangxinshi pills on the basis of conventional treatment can improve exercise tolerance of patients with coronary heart disease, improve quality of life or restore social function and mental health
