Active clinical trials for "Coronary Artery Disease"

Compare completeness and modality of revascularization, operative and postoperative results and 1 year clinical outcomes in unselected high risk patients referred for primary coronary artery bypass surgery. Patients will be randomized to undergo off-pump coronary artery bypass graft (OPCAB) or coronary artery bypass graft with cardiopulmonary bypass (CPB/CAB).

Physicians tend to always use the lowest dose of statins to initiate therapy even in subjects who require large reductions in cholesterol. The study evaluates if selecting the starting dose based on baseline and target LDL-C cholesterol would provide better results (ie proportion of subjects resching target)

Coronary artery disease is the first cause of death related to atherothrombosis.

The 5-milligram (mg) dose of prasugrel in low body weight (LBW) patients with coronary artery disease produces a pharmacodynamic response within the same therapeutic range as 10-mg dose in higher body weight (HBW) patients.

Compared with bare metal stents (BMS), both paclitaxel-eluting stents (PES) and sirolimus-eluting stents (SES) significantly reduce angiographic restenosis and the need for repeat revascularization in coronary arteries across a broad range of patient and lesion types. However the increased risk of very late stent thrombosis represents a major concern for patients treated with both PES and SES. Optical coherence tomography (OCT), a new imaging technique based on the back reflection of near infrared light, enables real-time, full tomographic, in-vivo visualization of coronary vessel microstructure. Struts coverage and vessel response of drug eluting stent (DES) compared to BMS are the most immediate clinical applications of OCT. Thickness of coverage and strut apposition can be quantified at micron-scale level with a resolution 10-30 times higher than conventional intravascular ultrasound (IVUS). The objective of this study OCTEVEREST (Optical Coherence Tomography for EVERolimus Eluting STent) is to evaluate the long term struts coverage and vessel wall response (abnormal intraluminal defects, strut malapposition, vessel expansions) to the PROMUS™ Everolimus Eluting Stent compared to PROMUS ELEMENT™ Everolimus Eluting Stent implanted for the treatment of stenosis in native coronaries. To investigate the completeness of struts coverage as well as the proportion of malapposed struts and the neointima characteristics, high resolution (~ 10 µ axial) intracoronary Optical Coherence Tomography (OCT) and intravascular coronary ultrasound (IVUS) will be used.

Coronary artery bypass grafting (CABG) is a procedure that people with coronary artery disease (CAD) may undergo to increase blood flow to the heart. During a CABG procedure, people who have a leak in one of the valves in the heart-the mitral valve-may at the same time undergo a procedure that repairs the valve. This study will evaluate whether people with moderate mitral valve leakage would be better off undergoing CABG plus the mitral valve repair procedure or undergoing CABG alone.

The purpose of this study is to determine whether treatment of Rosuvastatin (CRESTOR™) or Simvastatin given as monotherapy or given in combination with Ezetimibe, will lower the Low Density Lipoprotein Cholesterol (LDL-C) in patients with Hypercholesterolaemia and Coronary Heart Disease (CHD) or a CHD Risk Equivalent, Atherosclerosis or a 10-year CHD Risk of >20%

The aim of the present study was to evaluate the usefulness of an algorithm based on hemodynamic parameters obtained by single transpulmonary thermodilution (STD) combined with continuous monitoring of central venous oxygen saturation (ScvO2) for perioperative management of patients undergoing OPCAB.

The aim of AUTAX study is to investigate the frequency of MACCE in patients with multivessel disease and multiple Taxus stent implantations in the "real world" stenting at 30 days, 6 and 12 months at 2 year follow-up. Because multivessel stenting using DES has been limited due to economic considerations, the secondary aim is to enhance experience in multivessel stenting with drug-eluting stents in order to improve short- and long-term outcomes of the patients with severe multiple coronary artery stenoses. The objectives of the study are: To determine the frequency of MACCE at 30-day, 6 and 12-month and at 2 year clinical follow-up after multivessel intervention with drug-eluting stents in a prospective patient cohort.. To determine the rate of in-stent restenosis, target lesion and target vessel revascularization (angiographic measures) 6 months in patients with multiple DESs in multiple lesions. To investigate the clinical and angiographic outcomes after implantation of multiple DESs in the subgroup of patients with accompanying diseases (diabetes mellitus, renal insufficiency) with known high restenosis and late complication rate. To evaluate potential cost burden in attempting a strategy of complete revascularization by multiple DES in patients with multivessel disease.

The purpose of the study is to determine the drug characteristics of Ticagrelor, and to determine if 4 weeks treatment will reduce the blood clotting.
