2018-03-23 · Perspective: This study reports that plaque erosion tended to occur in younger patients, especially in premenopausal women with age . 50 years.. Current smoking was the predominant coronary risk factor of plaque erosion rather than dyslipidemia, hypertension, chronic kidney disease, or diabetes mellitus, and plaque erosion was most frequently located in the LAD with a limited focal Pathology and in vivo imaging studies have identified superficial plaque erosion as a frequent and important mechanism underlying acute coronary syndromes (ACS). In contrast with plaque rupture, the pathophysiological mechanisms leading to plaque erosion remain poorly understood.
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.
•. 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).

Pathological studies have shown that plaque erosion often develops on intimal thickening or a fibroatheroma, with few lipid core and calcification. The exposed intima at the eroded site is predominantly comprised of vascular smooth muscle cells and proteoglycans. However, the characteristics of nonculprit plaques in patients with acute coronary syndromes caused by plaque erosion are unknown. 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.

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. Plaque erosion is characterized by endothelial cell desquamation and small intraluminal thrombi, and now accounts for ≈25% to 30% of all ACS. 1 Article, see p 33 Neutrophils are the most abundant white blood cells and form the first line of defense against microbes and bacteria. Plaque erosion is responsible for 25% to 40% of patients with acute coronary syndromes (ACS).

(a) Plaque erosion, only reddening with no evidence of trans-cap ruptures, (b) plaque rupture, perforation of a fibrous cap overlying lipid core Fig. 8.2 Coronary angiography and intravascular imaging in patient with ST-segment elevation myocardial infarction not related to plaque rupture. Plaque erosion is associated with myocardial infarction (MI) in about 30% of cases and may require a different management approach to plaque rupture. The investigators hypothesise that plaque erosion leads to higher levels of apoptotic circulating endothelial cells (CECs) compared to plaque rupture. 2021-03-31 · Introduction. Atherosclerotic plaque disruption can trigger thrombosis, causing restriction or total occlusion of blood flow and myocardial ischemia. Within the coronary circuit, approximately 65% The plaque associated with an erosion may be quite small, or there may not be a plaque beneath the erosion at all.

Prevent Tartar and Plaque Buildup on Teeth; Tartar: The Hard Truth. Lots of people ask their dental professional if there's a difference between Help your patients understand how eating and drinking acidic food and drinks can cause enamel erosion and the wearing a way of tooth enamel. Aug 2, 2019 We all have plaque on our teeth. It's a group of bacteria that lives in your mouth and forms between brushings. The best way to keep plaque in Feb 1, 2021 Dental erosion occurs when acidic substances wear away tooth enamel. Learn the risk factors, common symptoms, treatment options Oct 15, 2019 Sudden plaque rupture and clotting cause heart muscle to die. This is a heart attack.
Severe stenosis of a dominant left V2 vertebral artery segment was identified on digital subtraction angiography (DSA) with an irregular intraluminal filling defect immediately above the stenosis. Optical coherence tomography (OCT) demonstrated a normal lumen 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. Arbustini E, Dal Bello B, Morbini P, et al. Plaque erosion is a major substrate for coronary thrombosis in acute myocardial infarction.
