Active clinical trials for "Myocardial Ischemia"

To describe the natural history of the coronary atherosclerotic plaque development and progression over time by CCTA with demographic and laboratory data for refinement of risk stratification of patients referred for CCTA.

This prospective, randomized trial will compare the extent of covered stent strut segments by assessed by Optical Coherence Tomography (OCT) of the ORSIRO DES with that of the XIENCE PRIME DES, which is the standard of choice of contemporary drug eluting stents (DES).

The purpose of this research is to study whether a multidisciplinary education in Diabetes and intervention for cardiac risk reduction in a group setting to modify patient behavior and adjust medications can achieve diabetes guideline goals for glycemia, blood pressure and lipid control.

Randomized nine months clinical comparison of implantation of Taxol eluting (Taxus Express) and Sirolimus eluting (Cypher Select) stents in non-selected patients with coronary artery disease.

The study investigated if aerobic endurance exercise of different intensity has different impact on the physical capacity and myocardial function in patients with coronary artery disease. Patients with stable CAD trained for 10 weeks, and oxygen consumption and myocardial function were measured before and after this period. Patients were randomly assigned to each exercise group.

The study aims to assess whether a SIMPLE or a COMPLEX strategy is best for the treatment of coronary bifurcation stenoses.

The aim of the DARE study is to see whether strict glycemic control during cardiac rehabilitation may ameliorate the improvement of exercise capacities (VO2 peak, peak workload, ventilatory threshold)in patients with type 2 diabetes with coronary artery disease.

Patients experiencing a mild heart attack will receive one of two medications which thin the blood to discern which is superior.

The sponsors of this investigational drug are developing prasugrel (also known as CS-747) as a possible treatment for patients with acute coronary syndrome (heart attack or chest pain) who need, or are expected to need, a percutaneous coronary intervention (PCI; also called a balloon angioplasty). Prasugrel was compared with Clopidogrel to determine which drug is better at reducing deaths, future heart attacks, or stroke.

This study is designed to compare two different echocardiographic techniques in the evaluation of heart disease (coronary artery disease). Both tests called Myocardial Contrast Echocardiography with Pharmacologic Stress and Stress Echocardiography with Dobutamine, are performed using a standard echocardiographic machine. Myocardial Contrast Echocardiography (MCE) does not use radioactivity. It uses sound waves like standard echocardiography. However, with MCE patients receive an injection of a "contrast agent" directly into the blood stream through a vein. The contrast agent, called Optison, is made of tiny microbubbles smaller than red blood cells. The echocardiogram can detect these microbubbles in the small blood vessels of the heart muscle and allow researchers to find areas of the heart receiving less blood flow than others. It is important to observe the heart during exercise because there are changes in blood flow. Since MCE cannot be performed when the patient is exercising, researchers give medication (adenosine) that stimulates the heart and creates a situation similar to exercise. Stress Echocardiography with Dobutamine does not use radioactivity. It uses sound waves like standard echocardiography. During this echocardiogram patients receive doses of a medication called dobutamine that stimulates the heart to beat stronger and faster. The purpose of this study is to evaluate the accuracy of MCE compared to stress echocardiography at detecting coronary artery disease (CAD).
