Background Plaque erosion is responsible for 25% to 40% of patients with acute coronary syndromes (ACS). Recent studies suggest that anti-thrombotic therapy without stenting may be an option for this subset of patients. Currently, however, an invasive procedure is required to make a diagnosis of pla …

Plaque erosion has three unique morphological characteristics — preserved vascular integrity, larger lumen area, and platelet-rich thrombus — which suggest that thrombus removal and effective

スポンサーリンク. plaque erosionが原因となるacute coronary syndromes with intact fibrous cap (IFC-ACS)はACSのACSの約3分の1を占めているとされています。. しかし、plaque ruptureによるACS（RFC-ACS）と比較して、そのメカニズムはほとんど解明されていません。. OPTICO-ACS studyでは、ACSの原因となるintact fibrous capによるACSのculprit lesionの微小環境を調査しました。.

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). • How to treat: Plaque erosion is responsible for 25% to 40% of patients with acute coronary syndromes ( ACS ).

A less common substrate, plaque erosion, is not associated with elevated cholesterol and is the prime cause of coronary thrombosis in premenopausal women. The characteristic histologic features are abundant surface smooth muscle cells and proteoglycans, and a small or absent lipid rich core.

However, damage can also occur from eating certain foods, drinks and from bad habits. Foods with acidic qualities can create erosion.

1 In both clinical studies using intravascular imaging and autopsy data from subjects dying suddenly, plaque erosion is the second most common cause of coronary thrombus. Plaque Erosion In Vivo Diagnosis and Treatment Guided by Optical Coherence Tomography Sining Hu, MD,*y Haibo Jia, MD, P H D,*y Rocco Vergallo, MD,y Farhad Abtahian, MD, P H D,y Request PDF | Plaque Erosion | Plaque rupture and erosion are the two most common causes of acute coronary syndromes (ACS). 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.

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.

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. The plaque associated with an erosion may be quite small, or there may not be a plaque beneath the erosion at all.
