Active clinical trials for "Coronary Disease"

This study assesses the impact of diastolic heart failure on exercise capacity in women who have a previous coronary condition. All the participants will go through the same evaluation.

Study evaluates the new technique MyoVista™ iECG sensitivity and ability to predict myocardial diseases, comparing iECG results with Computed Tomography Coronary Angiography findings

The purpose of this study is to examine the role of every day experiences as they relate to coronary artery disease (CAD).

The Cardiovascular disease research using Linked Bespoke studies and Electronic Records (CALIBER) e-health database was the data resource for this study. CALIBER links patient records from four different data sources: Clinical Practice Research Database (CPRD), MINAP (Myocardial Ischaemia National Audit Project registry) Hospital Episodes Statistics (HES), the Office for National Statistics (ONS).

The primary objective of this study is to assess whether inflammatory receptors play a role in the pathogenesis of atherosclerosis.

The investigators will evaluate 100 regular red wine consumer men and 100 abstainers men from 50 years-old to 70 years-old by coronary risk prevalence, mood status, anthropometric measures, daily caloric ingest, lipid profile, carotid intimal media thickness, brachial flow mediate dilatation, coronary tomographic angiography and leucocyte telomere length. The sample size has been calculated expecting that regular red wine ingestion would lead to a five year old younger vascular ageing indexes measured by carotid intimal media thickness, coronary artery calcium scores and leucocyte telomere length longer than those abstainers subjects at same age. The investigators hypothesized that regular wine consumers present less coronary lesion and coronary calcium score on coronary tomographic angiography, lower carotid intimal media thickness and higher mean telomere length due the benefice of wine.

Coronary computed tomographic angiography (CCTA) has emerged as a non-invasive test, accurately evaluate anatomic coronary artery stenosis. However, anatomically-obstructive coronary stenosis by CCTA demonstrates an unreliable relationship to lesion-specific ischemia. Recently, with the advance of imaging reconstruction and analysis technique, several novel parameters computed from CCTA were suggested to have added value in determining the ischemia-causing coronary stenosis. In this study, diagnostic performance of transluminal attenuation gradient (TAG) and fractional flow reserve computed form CCTA (FFR-CCTA) for the presence of hemodynamically-significant coronary stenosis, as determined by fractional flow reserve (FFR).

The purpose of this trial is to compare the clinical significance of the main vessel and the side branch vessel using EKG, pain score and coronary wedge pressure to develop a new scoring system to predict the clinical significance of a side branch

Study Type: Observational Study Design: Observational Model: Defined Population Observational Model: Natural History Time Perspective: Longitudinal Time Perspective: Prospective

1) Establish normal value for coronary calcium scoring in Taiwan. 2) Find out the relationship of coronary calcium deposition and coronary artery stenosis. Propose a clinical management guideline based on coronary calcium score. 3) Evaluate sensitivity/specificity of coronary CT angiography and the influence of coronary calcium score on coronary CT angiography. 4) Evaluate the clinical application of myocardial enhancement measurement.
