Atherosclerotic carotid plaque segmentation [PDF]

open access: yesThe 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
Atherosclerosis is the major cause of heart attack and stroke in the western world. In this paper we present a computerized method for segmenting the athrerosclerotic carotid plaque from ultrasound images. The method uses the blood flow image first to detect the initial contour of the plaque, and then despeckle filtering and snakes to deform the ...

Effects of norepinephrine on plaque hypoxia in atherosclerotic rabbits

open access: yesFrontiers in Cardiovascular Medicine, 2023
BackgroundHypoxia plays a vital role throughout the whole process of atherosclerotic vulnerable plaque formation, which may be induced by a reduced oxygen supply.

The Role of Matrix Metalloproteinase-9 in Atherosclerotic Plaque Instability

open access: yesMediators of Inflammation, 2020
Matrix metalloproteinase-9 (MMP-9) belongs to the MMP family and has been widely investigated. Excessive MMP-9 expression can enhance extracellular matrix degradation and promote plaque instability.

Research Progress on the Risk Factors and Outcomes of Human Carotid Atherosclerotic Plaques

open access: yesChinese Medical Journal, 2017
Objective: Atherosclerosis is an inflammatory process that results in complex lesions or plaques that protrude into the arterial lumen. Carotid atherosclerotic plaque rupture, with distal atheromatous debris embolization, causes cerebrovascular events ...

Intermedin1-53 attenuates atherosclerotic plaque vulnerability by inhibiting CHOP-mediated apoptosis and inflammasome in macrophages

open access: yesCell Death and Disease, 2021
Atherosclerotic plaque vulnerability and rupture increase the risk of acute coronary syndromes. Advanced lesion macrophage apoptosis plays important role in the rupture of atherosclerotic plaque, and endoplasmic reticulum stress (ERS) has been proved to ...

Comparative study on hemodynamic environments around patient-specific carotid atherosclerotic plaques with different symmetrical features

open access: yesMedicine in Novel Technology and Devices, 2021
Atherosclerotic plaque near the carotid sinus is a key risk factor for ischemic stroke. Although disturbed hemodynamic environments around atherosclerotic plaque had been investigated in many studies, the effect of their symmetrical features, especially ...

Exploration of the atherosclerotic plaque

open access: yesBiomedicine & Pharmacotherapy, 1990
During the past 3 decades we have achieved a better understanding of the atherosclerotic process. It has been described as a series of changes in the intima of arteries consisting of the focal accumulation of lipids, complex carbohydrates, blood and blood products, fibrous tissues, and calcium that are also associated with changes in the media.

Angiogenesis in the atherosclerotic plaque

open access: yesRedox Biology, 2017
Atherosclerosis is a multifocal alteration of the vascular wall of medium and large arteries characterized by a local accumulation of cholesterol and non-resolving inflammation. Atherothrombotic complications are the leading cause of disability and mortality in western countries.

Atherosclerosis and Atheroma Plaque Rupture: Imaging Modalities in the Visualization of Vasa Vasorum and Atherosclerotic Plaques

open access: yesThe Scientific World Journal, 2014
Invasive angiography has been widely accepted as the gold standard to diagnose cardiovascular pathologies. Despite its superior resolution of demonstrating atherosclerotic plaque in terms of degree of lumen stenosis, the morphological assessment for the ...

Characteristics and evaluation of atherosclerotic plaques: an overview of state-of-the-art techniques

open access: yesFrontiers in Neurology, 2023
Atherosclerosis is an important cause of cerebrovascular and cardiovascular disease (CVD). Lipid infiltration, inflammation, and altered vascular stress are the critical mechanisms that cause atherosclerotic plaque formation.
