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.

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

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. 2020-10-01 2021-02-01 56.3% plaque erosion in STEMI patients presented with noncritical stenosis, having distinct morphological features from erosion with critical stenosis. Fibrous plaque and nearby bifurcation were independently associated with the presence of noncritically stenotic plaque erosion, remaining a desire to tailor treatment therapy to individual patients. 2016-02-26 2019-12-30 2018-03-13 Request PDF | Plaque Erosion | Plaque rupture and erosion are the two most common causes of acute coronary syndromes (ACS).

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. Plaque Erosionの機序: OPTICO-ACS.

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

Thus, intensive antiplatelet therapy might benefit particularly ACS caused by superficial erosion. 2018-03-23 · Perspective: This study reports that plaque erosion tended to occur in younger patients, especially in premenopausal women with age . 50 years..

Ett allvarligt scenario uppstår om ett plack brister (plackruptur) eller plackhöljet skadas (plackerosion), vilket oftast beror på att inflammationen inuti placket blivit för

dyslipidemia, hypertension, chronic kidney disease, and diabetes mellitus) than those with plaque rupture. It is known that ACS is caused by coronary plaque rupture, plaque erosion, or rarely, calcified nodule, resulting in occlusive thrombus formation. 1,2 Ex vivo and in vivo studies have demonstrated that in approximately one third of patients, the mechanism responsible for ACS is plaque erosion. 23 – 28 In erosion, the culprit lesion typically 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.

Recent studies documented a higher prevalence of plaque erosion in non-STEMI, in women under 50 years of age, and in current smokers 21, 22.

Thus, plaque events ensue as a result of an intimal fibroatheroma in the coronary artery wall becoming vulnerable to erosion or rupture. Intimal erosion may give rise to platelet-rich, white thrombi, whereas clots that complicate plaque rupture have a more fibrin-rich ‘red’ character . Thus, intensive antiplatelet therapy might benefit particularly ACS caused by superficial erosion. Arbustini E, Dal Bello B, Morbini P, et al.

The plaque associated with an erosion may be quite small, or there may not be a plaque beneath the erosion at all. An erosion, just like a plaque rupture, can cause the formation of a blood clot. However, because an erosion (in contrast to a rupture), is not an acute event, the clot often forms much more gradually. EC sloughing and neutrophil invasion occur secondarily to stasis-induced venous thrombosis, 4 and thrombi precipitated by plaque rupture can produce the appearance of plaque erosion in neighboring segments. 2 The idea that erosions are preceded by plaques deprived of large regions of its endothelial lining may thus be far too simple. Rather, processes of EC loss, neutrophil recruitment, and thrombosis may occur simultaneously facilitating growth of thrombus across an erosion-prone lesion Plaque erosion is placed most in the proximal segment and near a bifurcation of the left anterior descending artery.

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 2021-03-23 · Plaque erosion is responsible for 25–40% of acute coronary syndromes and is more frequently observed in younger patients and smokers with a lower prevalence of hypertension, diabetes mellitus and dyslipidemia [ 7 ]. 2015-05-01 · Plaque erosion has been observed in ex vivo studies more frequently in females and young individuals 3, 6. In the main report from the OCTAVIA trial, we found that, when age matched, STEMI men and women did not show different mechanisms of coronary thrombosis . Similar findings were recently reported by Jia et al.
