Plaque erosion has three unique morphological characteristics — preserved vascular integrity, larger lumen area, and platelet-rich thrombus — which suggest that thrombus removal and effective 2021-02-01 · 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. 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.

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 Nrf2 system, which under normal situations helps protect the endothelium. Smoking is a known risk factor for plaque erosion. 2021-03-23 · True atherosclerotic plaque rupture can be distinguished from plaque erosion, spontaneous coronary artery dissection, coronary thromboembolism, or coronary spasm. These entities can be difficult/impossible to differentiate on angiography, and OCT may be required to establish the correct diagnosis and initiate appropriate therapy [ 14 ]. plaque erosion and 56% ruptured plaques.10 This observation suggests a new pathogenic hypothesis for local thrombogenic substrates and widens the morphological spectrum of risky coronary lesions in vivo. Our aim in the present study was to evaluate the prevalence of plaque erosion as a substrate for acute thrombosis in patients who died in 2019-08-31 · Objectives: This study sought to investigate the ability of near-infrared spectroscopy intravascular ultrasound (NIRS-IVUS) to differentiate among plaque rupture (PR), plaque erosion (PE), and calcified nodule (CN) in acute myocardial infarction (AMI) using an optical coherence tomography (OCT) diagnosis as a reference standard.

Plaque Erosion.

Plaque erosion is a major substrate for coronary thrombosis in acute myocardial infarction. Heart. 1999;82:269−72. Beltrame J, Crea F m.fl.

The culprit lesions were classified as plaque rupture (PR), erosion (OCT-erosion), calcified nodule (OCT-CN), or with a new set of diagnostic criteria for OCT. Results: The incidences of PR, OCT-erosion, and OCT-CN were 43.7%, 31.0%, and 7.9%, respectively. Patients with OCT-erosion were the youngest, compared with those with PR and OCT-CN (53.8 ± 13.1 years vs.

que erosion.” Pathologically, eroded plaques are rich that lesions responsible for AMI with plaque erosion Plaque rupture and plaque erosion as underlying.

Plaque Erosionの機序: OPTICO-ACS. 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。. Se hela listan på academic.oup.com Plaque Erosion. Frank D Kolodgie.

Objective To investigate the nonculprit plaque phenotype in patients with acute coronary syndrome according to culprit plaque pathology (erosion vs rupture) by 3-vessel optical coherence tomography imaging.

2 More notably, neutrophils are often present. 3 But, autopsies cannot tell for sure whether the missing endothelium and neutrophil accumulation were the cause or result of thrombosis.
