Active clinical trials for "Coronary Artery Disease"

The aim of the present study is to investigate wether endothelial dysfunction associated with stable coronary artery disease is altered by selective aldosterone antagonism with Eplerenone as potential anti-inflammatory drug versus placebo. Additionally we hypothesize that selective aldosterone antagonism reduces systemic inflammatory response such as C-reactive proteine, oxidative stress and pro-inflammatory cytokines.

The purpose of this study is to assess the long-term clinical outcomes after stenting bifurcation coronary artery lesions, and to determine whether simple or more complex techniques are associated with a better clinical outcome. We will also assess the risk factors associated with poorer clinical outcomes

To investigate the relationship of vascular cell phenotypes to atherosclerosis.

Despite advances in prevention and treatment, clinical manifestations of atherosclerosis (e.g. myocardial infarction, stroke) remain the largest cause of mortality in the Western world. The occurrence of acute ischemic syndromes, including unstable angina and myocardial infarction, is highly associated with atherosclerotic plaque morphology. Magnetic resonance (MR) imaging is able to noninvasively depict the lumen of coronary arteries without the need for ionizing radiation. In addition, MR imaging is able to generate soft-tissue contrast unlike any other imaging modality. It has been shown in the aorta and carotid artery that MR imaging is able to identify different atherosclerotic plaque components in vivo. Similar MR imaging techniques are becoming available to visualize the coronary arterial wall and preliminary studies have shown the feasibility of MR coronary vessel wall imaging in humans. The overall aim of the current study is to identify in vivo MR coronary vessel wall and plaque features that are associated with acute coronary syndromes. This study is divided into 2 substudies: Detection of atherosclerosis in the coronary vessel wall with contrast-enhanced MR imaging in patients with coronary artery disease and age-matched healthy volunteers. Characterization of coronary vessel wall plaque morphology in patients with stable and unstable angina: validation of MRI with the current standard of reference intravascular ultrasound (IVUS).

Prospective, open-labeled First in Man Clinical Investigation enrolling patients with visually estimated nominal vessel diameter of 3.0 mm receiving a single 3.0 x 12 mm or 3.0 x 18 mm BVS EECSS containing 98 microgramme per cm² of surface area.

The first aim of this study is to determine how often unrecognized myocardial infarction occur in patients using a magnetic resonance imaging (MRI) technique (known as delayed enhancement MRI), as compared to the electrocardiogram. The second aim of this study is to determine the severity of coronary heart disease of the patients with unrecognized myocardial infarction. The final aim is to determine how the presence of unrecognized myocardial infarction detected by the MRI affects lifespan.

Patients with underlying cardiovascular disease are at high risk of perioperative cardiovascular events and death. Hemodynamic variables are controlled by the autonomic nervous system reflected by Heart Rate Variability. To investigate whether differences of HRV parameters predict perioperative cardiovascular events.

Complete normalization of CFR following AVR for aortic stenosis was observed only for stentless valves. Besides the superior hemodynamic performance this might explain the excellent long term results of this valve design.

The purpose of the trial is to investigate the accuracy of coronary CT compared to the conventional "gold standard" cardiac catheterization.

The purpose of this study is to compare cardiac MRI with positron emission tomography (PET) with fluorodeoxyglucose (FDG) to determine if cardiac MRI images are as good as, or better, than PET with FDG.
