Active clinical trials for "Coronary Artery Disease"

The aim of the study is to investigate whether the expression and production of adipokines secreted by the epicardial adipose tissue correlate with the degree of coronary atherosclerosis.

is to test the hypotheses that epicardial adipose tissue can be a marker of severity of coronary artery disease in myocardial infarction patients

This translational study was designed to explore the association of the quantity and quality of epicardial adipose tissue (EAT) with coronary artery disease (CAD), left atrial remodeling and postoperative atrial fibrillation in a high cardiovascular disease-risk population. The investigators expect to identify new biochemical factors and biomarkers in the crosstalk between the epicardial adipocytes, coronary plaques and atrial cardiomyocytes that are involved in the pathogenesis of atherosclerosis and atrial fibrillation, respectively.

The study aims to evaluate the decision-making pathways of interventional cardiologists, when assessing patients, presented with stable coronary artery disease.

To compare the 3 - year clinical follow - up results of patients with left main bifurcation lesions treated by intravascular ultrasound(IVUS) - guided and coronary angiography(CAG) - guided percutaneous coronary intervention(PCI), and to confirm the clinical benefits of optimizing interventional therapy of left main bifurcation lesions by intravascular ultrasound(IVUS).

The purpose of this research study is to investigate the link between age-related macular degeneration (AMD or ARMD) and coronary artery disease (CAD). Age-related macular degeneration is a medical condition which may result in blurred or no vision in the center of vision. Coronary artery disease is a blockage of one or more arteries that supply blood to the heart. The study will specifically look at the macular changes that occur in the retina, which is the sensory membrane that lines the inner surface at the back of the eyeball, and the relationship between coronary heart disease and the risk factors.

The purpose of this study is to investigate the change of cholesterol efflux capacity in patients with coronary artery disease treated with secondary prevention drugs, and the correlation with the prognosis.

We will perform a systemic review of previously published data and an updated patient-level meta-analysis of studies, including the most recent publications. PubMed, EMBASE, Cochrane Central Register of Controlled Trials, the United States National Institutes of Health registry of clinical trials, and relevant websites were searched for pertinent published studies.

Overcrowding in the emergency department is an increasing problem in hospitals worldwide. Point-of-care Troponin (POC cTn) testing combined with a well investigated risk stratification tool (HEART-score) used in the ambulance may contribute to more rapidly diagnostics of ruling in or ruling out myocardial infarctions (MI) and subsequently reduce unnecessary hospital admissions, total admission time and costs. However, the applicability of the POC cTn and the HEART-score in the pre-hospital setting remains unclear. This study will evaluate this applicability.

Rationale: coronary microvascular disease is a relatively 'new' entity within the field of cardiology. The investigators are able to investigate the microcirculation by measurements performed in the catheterization laboratory. But even though measurements are performed on a daily basis, a lot of questions regarding microvascular disease remain. The rationale of this registry is to get an overview of patients and measurement values in daily routine practice. Objective and main endpoint: No previous registries have been set-up where coronary blood flow and resistance was systematically stored. Therefore the analyses will be mainly descriptive. The objective is to acquire a better insight in the indications and use of this technique in everyday practice , its consequences for clinical decision making, and to enable interventionalists to exchange mutual knowledge about this specific methodology and about the coronary microcirculation in general. Study design: prospective registry Study population: All patients who underwent coronary angiography with or without coronary intervention for any reason and if an indication for the foreseen intracoronary physiologic measurements is present according to the discretion of the operator. Intervention (if applicable): none, only usage of measurement data. The only 'intervention' for all patients is a questionnaire.
