Active clinical trials for "Myocardial Ischemia"

The purpose of this study was to evaluate the difference in the effect of coronary plaque regression (as measured by intravascular ultrasound [IVUS] imaging) between cholesterol absorption inhibitor and cholesterol synthesis inhibitor.

Coronary artery disease is the leading cause of death in USA. Contemporary cardiac care has substantially reduced mortality and morbidity in patients with severe coronary artery disease. However, patients with mild to moderate coronary artery stenosis (<70% stenosis) often present in the future with life threatening acute coronary syndrome which carries significant mortality and morbidity. It is difficult to predict outcomes in these patients before the events because the lack of complete understanding of the mechanisms underlying acute coronary syndrome and the lack of reliable markers that will predict major adverse cardiac events (MACE). Tissue-type plasminogen activator (t-PA) is released from endothelial cells and a major factor that prevent thrombosis in the coronary artery, the cause of acute coronary syndrome. Endothelial dysfunction impairs t-PA release. Therefore, we hypothesize that patients with impaired coronary artery t-PA release will have significantly higher risk for future MACE due to intrinsic fibrinolytic dysfunction that leads to increased thrombosis risk. To test this hypothesis, we will determine whether intrinsic endothelial fibrinolytic dysfunction predicts MACE in patients with non-significant CAD. The study will measure t-PA release mediated by bradykinin, a major mediator for t-PA release. This will involve infusion of bradykinin into left main coronary artery of individuals who have undergone routine cardiac catheterization (clinically indicated). We will take blood samples from the coronary sinus and measure t-PA and plasminogen activator inhibitor-1 antigen and activity levels.

The purpose of this study is to evaluate whether adding estradiol to rapamycin better prevents coronary artery reblockage after drug-eluting stent implantation.

To evaluate the impact of ranolazine extended-release tablets in women with subendocardial ischemia due to microvascular endothelial dysfunction on myocardial ischemia (Cardiac Magnetic Resonance (CMR) extent, severity. To evaluate the impact of ranolazine extended-release tablets in women with subendocardial ischemia due to microvascular endothelial dysfunction on the outcomes of angina (Seattle Angina Questionnaire (SAQ), WISE angina frequency, Duke Activity Status Inventory(DASI) and SF-36).

The purpose of this study is to evaluate the efficacy and safety of intramyocardial injections of CLBS14 in patients with refractory chronic 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.

This study is being conducted to compare the efficacy, safety, and tolerability of ezetimibe/simvastatin 10/20 mg when administered daily versus doubling the dose of simvastatin to 40 mg in patients with hypercholesterolemia and coronary heart disease.

The primary purpose of this study is to assess the safety and tolerability of E5555 in subjects with coronary artery disease.

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.
