Human coronary artery atheroma that give rise to thrombosis because of erosion differ diametrically from those associated with fibrous cap rupture. Eroded lesions

Unlike the prominent fibrous cap inflammation described in ruptures, eroded surfaces contain fewer macrophages and T lymphocytes. Taken together, eroded plaques tend to be eccentric lesions rich in

Plaque erosion

Plaque erosion is placed most in the proximal segment and near a bifurcation of the left anterior descending artery. Near a bifurcation is anatomically the most significant predictor of plaque erosion. Thrombus involved with plaque erosion occurs in fibrous or non-lipid plaques without TCFA and macrophages with larger lumen vessel. Coronary plaque erosion: a clinical case. Definition. • 25% of thrombotic coronary occlusions • Plaque erosion was identified when the fibrous cap of the culprit lesion was intact (thrombus often overlies atherosclerotic plaque without evident disruption of the fibrous cap).

In contrast, plaque erosion most frequently occurs on stenotic plaques in areas of elevated flow. This changes the behaviour of endothelial cells and primes the

Plaque erosion was more frequent in women <50 years when compared with those ≥50 years of age. Patients with plaque erosion were more frequently smokers but had fewer other coronary risk factors (e.g.

Although plaque rupture has been well-characterized | Find, read and Among plaque erosion, white thrombus was seen in 55.8% (24/43) of patients and red thrombus in 27.9% (12/43) of patients. Compared to plaque erosion, plaque rupture more often showed positive remodeling (p=0.003) with a larger necrotic core area examined by virtual histology (VH)-IVUS, while negative remodeling was prominent in plaque erosion. Unlike the prominent fibrous cap inflammation described in ruptures, eroded surfaces contain fewer macrophages and T lymphocytes. Taken together, eroded plaques tend to be eccentric lesions rich in plaque erosion; rupture; acute myocardial infarction; Plaque rupture is the major local substrate for acute coronary thrombosis, causing unstable angina, acute myocardial infarction, and sudden ischaemic death.1-3 The vulnerable plaque that is prone to rupture consists of a necrotic core with a thin fibrous cap infiltrated by inflammatory cells,4 especially metalloproteinase-rich macrophages.5 Plaque Rupture Video - YouTube. Plaque Rupture Video.

Mar 26, 2019 Plaque rupture is the dominant initiating event, responsible for 60–70% of acute coronary syndromes (ACS), while plaque erosion is

Arterioscler Thromb Vasc Biol . 2002 ; 22 :1642–1648. Mechanisms of erosion have received much less attention than those that provoke plaque rupture. Intensive statin treatment changes the characteristic of plaques that render them less susceptible to rupture. Thus, erosion may contribute importantly to the current residual burden of risk. Understandin … Posts about plaque erosion written by dr s venkatesan.

plaque erosion: presence of the attached thrombus overlying an intact and visualized plaque, luminal surface irregularity at the culprit lesion in absence of thrombus, or attenuation of the underlying plaque by thrombus without superficial lipid or calcification immediately proximal or distal to the site of thrombus, there are two types of plaques in atherosclerosis one is stable plaque which has lipid, foam cells, macrophages in the lesser amount then that of vulnerable plaque rupture (PR), plaque erosion (PE), or rarely calciﬁed nodule resulting in occlusive thrombus formation.1,2 Ruptured plaque is characterized by a disrupted ﬁbrous cap overlying a large necrotic core, and extensive inﬂammation.
