2016-02-26 · According to the landmark contribution of Farb et al. in 1996, which reported that plaque erosion occurred in 44% of patients who died due to acute MI (with an increased prevalence in women), there has been no firm agreement on the precise prevalence of plaque erosion versus rupture (Figures 1 and 2). 6,7,9 Indeed, this is a key issue because the management of rupture would conceivably entail

Plaque erosion

In contrast with plaque rupture, the pathophysiological mechanisms leading to plaque erosion remain poorly understood. The advent of intra … 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. 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.

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.

Oct 15, 2016 The step by step process of plaque rupture.

Plaque erosion is defined as an acute thrombus in direct contact with the intima in an area of denuded endothelium. Thus, plaque events ensue as a result of an intimal fibroatheroma in the coronary artery wall becoming vulnerable to erosion or rupture.
