Active clinical trials for "Myocardial Ischemia"

The clinical investigation is an international, prospective, multi-center, double-blind, randomized safety and efficacy trial. The purpose of this study is to evaluate the safety and effectiveness of the TAXUS(TM)Stent System with 1µg/mm2 (loaded drug/stent surface area) of paclitaxel incorporated into a moderate rate-release formulation of triblock copolymer carrier system in patients with a higher risk of target lesion revascularisation and restenosis.

The primary purpose of this study is to test the safety and the effects of using an investigational drug regimen; once daily ABT-335 (Investigational drug) administered in combination with once daily atorvastatin calcium, rosuvastatin calcium or simvastatin in patients with abnormal lipid levels in the blood.

The aim of this study is to investigate the effect of genistein administration on coronary arteries in humans. We will measure the size of a coronary artery and the speed and amount of blood flow in response after subjects have ingested Supro® drinks (a soy protein drink containing genistein).

The ultimate goal of a paclitaxel eluting stent system (TAXUS stent) is to prevent restenosis by blunting the initial response to stent implant injury and sustaining the arrested response until vascular healing has taken place. The purpose of the TAXUS IV-SR trial is to study the safety and efficacy of the TAXUS Stent under controlled trial circumstances used in the treatment of new coronary artery lesions (heart blockages) This clinical investigation will evaluate the safety and effectiveness of the TAXUS Stent with 1 ug/mm2 (loaded drug/stent surface area) of paclitaxel incorporated into a slow rate-release formulation of a triblock copolymer carrier system for treatment of new coronary artery lesions.

The purpose of this study is to determine whether the Ensure Medical Vascular Closure Device is more effective than standard manual compression at sealing the puncture made in the femoral artery following a cardiac or peripheral diagnostic or interventional procedure while maintaining the same level of safety.

This study was designed to assess the effects on coronary artery plaque using aggressive lipid-lowering therapy versus moderate lipid-lowering therapy. A substudy will examine the effect of these treatments on brachial artery vasoactivity.

The purpose of this study is to determine whether a particular substance involved in inflammation, called leukotrienes, is involved in causing heart disease to occur or to progress.

The purpose of the study is to determine whether BMS068645 is as effective as Adenosine SPECT at detecting blockages in heart arteries, and to determine if it will have fewer side effects

Regular exercise reduces the risk of heart problems, in part because it improves the work of the endothelium (the cells that line blood vessels). Exercise appears to release precursor cells from the bone marrow that will later become endothelial cells. A molecule called nitric oxide (NO) appears to be involved in this release. However, some heart patients do not improve their endothelial function despite regular exercise. The researchers believe that the heart disease in these patients may interfere with the normal relationship between exercise and endothelial function. This study is designed to test whether giving a patient nitroglycerin (which is converted to NO in the bloodstream) will increase the release of endothelial precursor cells from the bone marrow. If the study succeeds, it may lead to improved healing of arteries in heart disease patients. Adults may be eligible for this study if they have coronary artery disease and do not take nitroglycerin or nitroglycerin-like medication on a daily basis. Volunteers will be admitted to the Clinical Center on 2 separate nights at least 1 week apart. On the morning after each admission, volunteers will have blood drawn from an arm vein for laboratory tests, and then walk on a treadmill until fatigue or discomfort prevents further exercise, or until asked to stop. On one of their admissions, volunteers will receive 1 tablet of nitroglycerin under the tongue shortly before the treadmill test. Volunteers will be monitored by EKGs and blood pressure tests during the treadmill tests, and will have more blood drawn at about 15 minutes and 24 hours after each treadmill test. Researchers will examine the levels of endothelial precursor cells and nitric oxide in the blood samples taken before and after exercise.

The purpose of this study is to investigate additional cholesterol lowering effects in patients with coronary heart disease by giving an investigational drug with a patient's current approved cholesterol lowering medication.
