The characteristic histologic features are abundant surface smooth muscle cells and proteoglycans, and a small or absent lipid rich core. The mechanisms of plaque erosion are unclear, and there are no consistent risk factors, although patients are often smokers.

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. Heart 1999; 82:269.

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.

The mechanisms of plaque erosion are unclear, and there are no consistent risk factors, although patients are often smokers. Plaque erosion may involve a first step mediated by local flow perturbation around the plaque in the coronary artery, which activates the innate immune toll-like receptor 2, leading to endothelial cell death and desquamation on the plaque surface. 2 A second step, formation of neutrophil extracellular traps on the denuded endothelial surface, can propagate thrombus formation.

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. Plaque erosion and calcified nodule have not been systematically investigated in vivo. Endothelial cells (ECs) at the plaque-thrombus interface are generally absent, leading to the term plaque erosion, and macrophages are rarely conspicuous. 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. This Plaque erosion is placed most in the proximal segment and near a bifurcation of the left anterior descending artery.

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 ). Recent studies suggest that anti‐thrombotic therapy without stenting may be an option for this subset of patients.
2021-03-23 · True atherosclerotic plaque rupture can be distinguished from plaque erosion, spontaneous coronary artery dissection, coronary thromboembolism, or coronary spasm.
