Medicine 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 ...

Atherosclerotic carotid plaque segmentation [PDF]
The 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 ...

Percutaneous Coronary Intervention for Vulnerable Coronary Atherosclerotic Plaque.
Journal of the American College of Cardiology, 2020 BACKGROUND Acute coronary syndromes most commonly arise from thrombosis of lipid-rich coronary atheromas that have large plaque burden despite angiographically appearing mild.

Imaging atherosclerotic plaque inflammation [PDF]
Nature Clinical Practice Cardiovascular Medicine, 2008 Inflammation within atherosclerotic plaques is one of the main drivers of atherosclerotic plaque rupture, which frequently leads to clinical events such as myocardial infarction and stroke. Current gold standard techniques such as X-ray angiography and ultrasound can rapidly report on luminal encroachment but give no readout on inflammatory state of ...

Vulnerable Atherosclerotic Plaque [PDF]
Circulation, 2003 The recent proliferation of invasive and noninvasive techniques to locate vulnerable atherosclerotic plaques raises important questions. Will such techniques add useful prognostic information? If so, will the information prevent myocardial infarction, stroke, or death in at least some patients at risk? Will it lead to new research advances?

Exploiting macrophage autophagy-lysosomal biogenesis as a therapy for atherosclerosis [PDF]
, 2017 Macrophages specialize in removing lipids and debris present in the atherosclerotic plaque. However, plaque progression renders macrophages unable to degrade exogenous atherogenic material and endogenous cargo including dysfunctional proteins and ...

Atherosclerotic carotid plaque composition: a 3T and 7T MRI-histology correlation study [PDF]
, 2016 Background and Purpose Carotid artery atherosclerotic plaque composition may influence plaque stability and risk of thromboembolic events, and non-invasive plaque imaging may therefore permit risk stratification for clinical management.
