Thus, erosion may contribute importantly to the current residual burden of risk. Understandin … Posts about plaque erosion written by dr s venkatesan. Retrospective angiographic studies and the prospective PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study have shown that plaques with severe stenosis carry a higher per-plaque risk for producing clinical events than plaques that cause no or non severe stenosis. 2018-03-01 Plaque erosion is reported to be responsible for about 25% to 40% of patients with acute coronary syndromes (ACS). 1, 2, 3 Current guidelines recommend early invasive strategy for all ACS patients except for the low‐risk subgroups 4, 5 and coronary stents are implanted in the majority of the cases. Recent studies reported that ACS patients with plaque erosion might be treated conservatively Plaque erosions are more often observed in younger individuals and smokers compared with plaque ruptures.

Request PDF | Characteristics of carotid atherosclerosis in patients with plaque erosion | Plaque erosion (PE) is a major underlying mechanism of acute coronary syndrome (ACS). Patients with PE 2 days ago 2020-05-29 A less common substrate, plaque erosion, is not associated with elevated cholesterol and is the prime cause of coronary thrombosis in premenopausal women.

1,2 Several groups have reported in vivo diagnoses of these underlying pathologies in patients with acute coronary syndrome (ACS) using optical coherence tomography (OCT), a high Thus, while the mechanisms underpinning plaque rupture are related to a systemic inflammation that eventually hits a vulnerable plaque, 1, 13–15 the mechanisms leading to plaque erosion might be related to a local trigger, such as local shear stress alterations promoting local inflammation, endothelial erosion, and thrombus formation.

MORPHOLOGICAL PLAQUE EROSION FEATURES CRITERIA: 1. absent or deeply seated necrotic core with an intact fibrous cap.

Thrombus involved with plaque erosion occurs in fibrous or non-lipid plaques without TCFA and macrophages with larger lumen vessel. 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 plaque erosion. MORPHOLOGICAL PLAQUE EROSION FEATURES CRITERIA: 1. absent or deeply seated necrotic core with an intact fibrous cap. 2.

This changes the behaviour of endothelial cells and primes the Mar 23, 2021 Coronary angiography and OCT revealed plaque erosion with subsequent subtotal thrombotic occlusion of the left anterior descending artery that Oct 13, 2020 Plaque erosion is responsible for more than one third of acute coronary syndromes (ACS) cases. •. Patients with plaque erosion have a better Mar 31, 2021 Endothelial erosion of atherosclerotic plaques is the underlying cause of approximately 30% of acute coronary syndromes (ACS).

Patients with plaque erosion were more frequently smokers but had fewer other coronary risk factors (e.g.

Assessment of culprit lesion morphology in acute myocardial infarction: ability of optical coherence tomography compared with intravascular ultrasound and coronary angioscopy. Intimal erosion may give rise to platelet-rich, white thrombi, whereas clots that complicate plaque rupture have a more fibrin-rich ‘red’ character .

dyslipidemia, hypertension, chronic kidney disease, and diabetes mellitus) than those with plaque rupture. Plaque erosion occurs without cap disruption where flowing blood comes into direct contact with intimal surface lacking endothelial cells. 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. 2021-03-31 · For example, plaque rupture occurs on inflamed and lipid-rich plaques with thin fibrous caps, contrasting with erosion-prone plaques containing abundant smooth muscle cells and few resident For decades, pathology reports have shown that there are 3 major underlying mechanisms for sudden cardiac death: plaque rupture, plaque erosion, and calcified nodule. 1,2 Several groups have reported in vivo diagnoses of these underlying pathologies in patients with acute coronary syndrome (ACS) using optical coherence tomography (OCT), a high-resolution intracoronary imaging modality.

A proof-of-concept study showed favorable out-comes with a non-stenting strategy in plaque erosion [13]. is may be of particular importance in young patients like the present case, where the long-term sequela after stent implantation could potentially be prevented. Die Plaqueerosion ist die zweithäufigste Ursache für einen Myokardinfarkt vom Typ 1 nach der Plaqueruptur und macht etwa 25 - 30% aller Typ-1-Myokardinfarkte aus. 4 Pathogenese Der genaue Pathomechanismus einer Thrombose auf dem Boden einer Plaqueerosion ist nicht bekannt. 2019-12-30 · Plaque erosion.

The advent of intravascular imaging techniques, particularly optical coherence tomography, has aided understanding • Plaque erosion was the underlying pathology in ¼ of patients with ACS. • Anti-thrombotic therapy without stent implantation effectively reduced thrombus volume and increased flow area without recurrent ischemic events at 1 month. 10 • Randomized trials will be needed to reproduce this pilot data Plaque Erosion as a Mechanism of Acute Coronary Syndromes (ACS) JN Learning™ is the home for CME and MOC from the JAMA Network.
