Active clinical trials for "Atherosclerosis"

The investigator prospectively enroll 30,000 outpatients who were suspected of coronary artery disease (CAD) and underwent cardiac computed tomography angiography (CTA). The endpoint was major adverse cardiac events (MACE).The investigator aim to evaluate the prognostic value of CTA, risk factors and bio-markers for MACE.

Cardiovascular diseases and stroke are the major causes of morbidity and death in Taiwan. There is a clear need to identify novel mediators of atherosclerosis in dyslipidemic patients to provide insights into the pathogenesis, to tailor clinical care based on cardiovascular risks, and to develop new therapeutic strategies. While the roles of lncRNAs in human diseases including cancer and neurodegenerative disorders are beginning to emerge, it remains unclear how lncRNA regulation contributes to atherosclerotic vascular diseases in patients with dyslipidemia. In this proposal, we seek to apply next-generation sequencing technology to investigate circulating (plasma and peripheral blood mononuclear cells [PBMC]) lncRNA expression in control subjects and in dyslipidemic patients with and without atherosclerotic vascular diseases (CAD, ischemic stroke and PAOD). The results from these experiments will lead to better understanding of how circulating lncRNAs contribute to atherosclerotic cardiovascular complications.

Familial hypercholesterolemia (FH) is a common inherited disorder with a frequency of 1 in 500 in the UK. Our aim is compare the carotid and coronary artery atherosclerosis in monogenic FH and polygenic hypercholesterolemia with means of a carotid ultrasound, a coronary CT angiogram and biochemical biomarkers.

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.

To investigate the diagnostic performance of whole body magnetic resonance angiography (WB-MRA) using two different magnetic resonance contrast agents.

The purpose of this study is to validate the usefulness of 64-slice multi-detecter computeted tomography as a screening tool in asymptomatic population.

Lipid-rich atherosclerotic plaques, or "vulnerable plaques" are prone to rupture, causing local intravascular thrombosis, with subsequent grave clinical consequences. Atherosclerotic plaques normally removed during surgery, and peripheral blood samples will be studied to achieve the following objectives: "1" Define histological features of the vulnerable plaque, analyze its physical characteristics, and investigate selected gene expression. "2" Study biomarkers of inflammation in conjunction with the presence of vulnerable plaques. "3" Explore the potential role of infection in atherogenesis.

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

The study is a epidemiological, cross-sectional study in a mainly rural area of Denmark in Denmark. Life expectancy is shorter, morbidity is higher, and social problems more prevalent than in the urban areas of the country. The population study aims at examining complexities of environmental, hereditary, lifestyle, and social factors as determinants and predisposing factors for morbidity, health, and quality of life. The study will cover physical, mental, and social dimensions and examine family patterns and subgroups. The study will provide baseline information for later follow-up.
