Active clinical trials for "Coronary Artery Disease"

The health-related quality of life questionnaire "EQ-5D" has been collected in connection with several interventional and observational studies where the no-touch vein harvesting technique in CABG has been used. The results of the questionnaires will be compiled and reported in this study.

Myocardial fibrosis is the fundamental substrate for the development of heart failure. Cardiovascular magnetic resonance (CMR) allows non-invasive assessment of myocardial fibrosis based on late gadolinium enhancement (LGE) and T1 mapping. Patients: Prospective longitudinal observational multicenter study of consecutive patients with suspected or known non-ischemic cardiomyopathy. Imaging: Non-invasive measures of myocardial fibrosis: native T1, extracellular volume fraction (ECV) and LGE. Primary endpoints: all cause and cardiovascular mortality. Secondary endpoints: arrhythmic composite and HF composite endpoints.

This is a validation study comparing a pulse wave based algorithm for the detection of coronary artery disease with parameters from coronary angiography, echocardiography and cardiogoniometry.

This is a multi centre, prospective trial. 250 patients will be enrolled in the study.(10 patients per centre involving approximately 25 centres). Patients will be followed up clinically for twelve months post-procedure at 1 month, 6 months & 12 months. All patients will have a repeat angiography at 8 months. Clinical follow-up will be maintained for years 3 & 5 post-implant.

The purpose of this research study is to determine if Intravascular Ultrasound (IVUS) grayscale and VH (Virtual Histology)-IVUS pre-stenting can assess more accurately the location, amount, and type of a blockage than angiogram alone. Additionally, this study is to determine if IVUS grayscale and VH-IVUS guidance will result in improved acute and long term procedural outcome vs. bifurcation stenting with only angiographic guidance in native coronary arteries.

Abstract Objectives: Primary: To study the association between central aortic blood pressure indices and coronary artery disease in patients undergoing elective angiography. Secondary: (a) To study whether any association exists between central aortic pressure indices and the incidence of major adverse cardiovascular events (MACE) in the same patients during a 6 month follow up period. (b) To study whether any association exists between the central aortic pressures and peripheral pressures. Methods: The investigators conducted a prospective observational study in consecutive patients undergoing coronary angiography. Central and peripheral pressures were invasively recorded and coronary artery disease (CAD) classified into obstructive and non-obstructive group. CAD severity was graded using the Gensini score and subjects were divided into tertiles. Patients were followed up and the role of central aortic pressure indices in the prediction of cardiovascular events were analysed.

The purpose of this study is to determine whether co-registration of OCT and angiography reduce geographic miss defined as stent edge dissection or significant residual stenosis at stent edge after stent implantation during percutaneous coronary intervention.

Coronary artery disease is a common medical disease in many populations. The pathogenesis of this disease is very complex. Surgery is one of the treatment choices. Assessing the risk factors will improve the surgical outcome. In this study some biochemical parameters were evaluated to find out the relationship between these parameters (electrolytes and albumin vs)

Background: Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome, which is one of the major risk factors of coronary heart disease (CHD). CHD is the most important manifestation of atherosclerosis, because of its immense morbidity and mortality. Transient elastography (TE, Fibroscan®) including the currently developed controlled attenuation parameter (CAP) is a non-invasive method for evaluation of liver fibrosis and steatosis, which is already implemented in routine care of patients with NAFLD. Hypothesis: The use of TE with CAP as screening for NAFLD might be an easy tool for risk assessment for CHD. Methods: Patients scheduled for routine coronary angiography will be screened for manifestation of NAFLD by TE including CAP, conventional ultrasound, clinical and laboratory parameters. Patients will be stratified for the presence of CHD based on the angiography results and correlation analysis with liver fat content will be performed. NFALD screening will be validated in a subgroup by MR-based measurements.

The aim of this study is to evaluate and describe the total coronary circulation time (TCCT) by using TIMI frame count method in patients performed coronary angiography. TCCT is described as an angiographic index which is the sum of the frame count of coronary artery and venous system. This study also evaluates the relationship between the diseases in arterial system such as coronary artery ectasia, coronary slow flow, coronary artery disease and coronary venous pathologies.
