Wall Shear Stress Analysis in Stenosed Carotid Arteries with Different Shapes of Plaque [PDF]
International Journal of Computer Applications, Volume 145, No.4,
July 2016, 2017 Atherosclerosis is a disease caused due to formation of plaque into the artery. Increase in plaque affects the wall shear stress. The present study is performed to calculate wall shear stress in different geometries of stenosed carotid artery. A 2D model of different geometries is generated using CFD for Non- Newtonian model.

Imaging Vulnerable Plaque by Ultrasound
Journal of the American College of Cardiology, 2006 Diagnostic techniques to identify vulnerable plaques are rapidly evolving. Intravascular ultrasound (IVUS) has the ability to detect and localize plaque as well as quantitate plaque burden. Recent IVUS studies have suggested that patients presenting with acute coronary syndromes have an approximate 25% incidence of additional ruptured plaques in ...

Frontiers in Physiology, 2022 Objectives: We aimed to explore sex-specific association between genes involved in inflammation and endothelial function and vulnerable carotid plaque, a subclinical precursor of ischemic stroke.Methods: Carotid plaque and plaque phenotype were assessed ...

Gene therapy for the vulnerable plaque
Journal of the American College of Cardiology, 1995 Acute coronary events result from the rupture of an atherosclerotic plaque, leading to formation of an occlusive coronary thrombus. Recent developments in the field of gene transfer provide the opportunity to genetically modify cells involved in plaque rupture as well as thrombus formation and thus prevent acute coronary syndromes.

Semantic decomposition Network with Contrastive and Structural Constraints for Dental Plaque Segmentation [PDF]
arXiv, 2022 Segmenting dental plaque from images of medical reagent staining provides valuable information for diagnosis and the determination of follow-up treatment plan. However, accurate dental plaque segmentation is a challenging task that requires identifying teeth and dental plaque subjected to semantic-blur regions (i.e., confused boundaries in border ...

Mechanisms of plaque vulnerability and rupture [PDF]
Journal of the American College of Cardiology, 2003 Rupture of atherosclerotic plaque has been identified as the proximate event in the majority of cases of acute ischemic syndromes. Plaque rupture exposes thrombogenic components of the plaque, activating the clotting cascade and promoting thrombus formation.

The Myth of the Mild Vulnerable Plaques
JACC: Cardiovascular Imaging, 2013 Few core concepts introduced in the past several decades have become more ingrained in the psyche of the cardiologist such as the belief that coronary occlusion and myocardial infarction most frequently evolve from a mildly stenotic coronary artery disease [(1)][1].

Automated detection of vulnerable plaque in intravascular ultrasound images [PDF]
, 2018 Acute Coronary Syndrome (ACS) is a syndrome caused by a decrease in blood flow in the coronary arteries. The ACS is usually related to coronary thrombosis and is primarily caused by plaque rupture followed by plaque erosion and calcified nodule. Thin-cap fibroatheroma (TCFA) is known to be the most similar lesion morphologically to a plaque rupture. In

Adiponectin and Vulnerable Atherosclerotic Plaques
Journal of the American College of Cardiology, 2011 High-risk plaques that are vulnerable to rupture demonstrate distinct morphological characteristics. They are differentiated from the lesions responsible for stable coronary artery disease by their large necrotic cores, thin-inflamed fibrous caps, and positive remodeling.

Insulin resistance, vulnerable plaque and stroke risk in patients with carotid artery stenosis
Scientific ReportsInsulin resistance (IR) is linked to both the vulnerable plaque and the stroke risk. However, the precise extent of this correlation and its impact on stroke risk in carotid artery stenosis patients remain unclear.
