Active clinical trials for "Plaque, Atherosclerotic"

The purpose of this study is to test the hypothesis that anti-IL-6 therapy is effective for reducing plaque inflammation as measured by fluorine-2-deoxy-D-glucose positron emission tomography (FDG-PET) in patients with rheumatoid arthritis (RA) who are synthetic disease-modifying antirheumatic drugs (dMARD) inadequate responders and are naive to biologic therapy.

The purpose of this study is to compare standard therapy (risk factor control, life style modification) versus standard therapy plus low-dose rosuvastatin therapy (5mg/day) on progression of coronary atherosclerosis in statin naive individuals who have mild CAD (nonobstructive coronary atherosclerotic plaques) and normal LDL (low-density lipoprotein) cholesterol levels(<130mg/dl).

The goal of this observational study is to determine the diagnostic accuracy of peripheral whole blood transcriptomes analyzed by an artificial intelligence algorithm to detect the presence and extent of coronary calcification in individuals without a history of known cardiovascular disease. The main question it aims to answer is: 1. Will the proposed method predict the presence and extent of coronary artery calcification from the peripheral whole-blood transcriptomes?

Fimasartan will be more beneficial in stabilizing the plaque vulnerability compared to control group in deferred coronary lesions. Fimasartan will be more beneficial in reducing total plaque volume compared to control group in deferred coronary lesions. Fimasartan will be more beneficial in reducing functional impairment of stenotic lesions (assessed by FFR:Fractional Flow Reserve) in deferred coronary lesions.

The goal of this observational study is to develop an automatic whole-process AI model to detect, quantify, and characterize plaques using coronary CT angiography in coronary artery disease patients. The main questions it aims to answer are: Whether the AI model enables to detect and quantify coronary plaques compared with intravascular ultrasound or expert readers; Whether the AI model enables to identify vulnerable plaques using intravascular ultrasound or optical coherence tomography as the reference standard. Whether the AI model enables to predict future adverse cardiac events in a large cohort of 10,000 patients with non-obstructive CAD.

The purpose of this study is to evaluate the effects of angiotensin receptor 1 blocker versus calcium channel blocker on atherosclerotic plaque inflammation using serial FDG PET/CT imaging of carotid artery.

This study aims to explore whether the increased supply of dietary plant sterols and plant stanols have any influence on serum levels of phytosterols and on consistency of carotid atheromatous plaques.

Type 2 diabetes is common in ethnic and, minority groups in developing and developed countries such as Africans, African Americans, Asians, Native Americans, Hispano-Latinos and Alaskan indians. A randomized controlled study to assess the efficacy of fermented papaya preparation and green tea infusates in latent diabetes (individuals newly diagnosed as diabetics) is proposed. Glycation products from excess glucose autooxidation can chemically modify DNA causing mutations and cause complex DNA rearrangements. Advanced glycation end-products which play a role as proinflammatory mediators in gestational diabetes can accelerate vascular occlusion by quenching the vasodilating agent nitric oxide. Interaction with high-affinity receptors located on monocytes and macrophages can enhance the production of free radicals and reactive oxygen/nitrogen species, the secretion of tumor necrosis factor-α, interleukin-1 and insulin-like growth factor I which can proliferate endothelial, mesangial and smooth muscle cells and hence contribute significantly to the pathogenesis of cardiovascular complications. The clinical markers include C-reactive proteins (inflammation indicators), protein C (markers of reno vascular injury), uric acid, natriuretic peptides, and the integrity of isolated adipocytes, glucose levels, lipid indices (triglycerides, total cholesterol, VLDL, HDL and LDL). Given that decreased functional activity of activated protein C affects the permeability of the glomerular capillary wall and enhances apoptosis of glomerular endothelial cells and adipodocytes, this has relevance to the pathophysiology of diabetic nephropathy. A second phase of the study is expected to commence after the first 16 weeks in order to assess the ability of the dietary factors to modulate atheroma formation and the integrity of drug therapy (upon commencement of treatment)on the prognosis of diabetes. This will be expected to last up to 3 years.

The purpose of this study is to examine the changes in the carotid artery when subjects receive high or low doses of rosuvastatin.

This study aims to address the following questions on the effects of testosterone therapy in men with coronary ischaemia: Does the anti-anginal effect persist long term? Many of the published studies are acute single dose trials and none of the chronic studies have assessed patients formally beyond a few months. The investigators' earlier studies were limited to 3 months. Does testosterone therapy in men affect the levels of measurable atheroma? There is currently no in-vivo human evidence that androgen therapy inhibits or reduces levels of atheroma, although there is abundant evidence in animals to suggest a potential improvement. This study addresses the two issues and would be of one-year duration but would be the longest trial of testosterone therapy in men with cardiovascular disease. The primary endpoint is the change in time to ST- segment depression of > 1mm during exercise testing.
