In other words: plaque tear or rupture or dissection/rupture due to plaque.

in that it seems most likely that plaque dissection represents a variant of a typical ACS caused by underlying atherosclerosis, whereas true SCAD occurring outside the setting of atherosclerosis represents a distinct clinical entity.

Plaque rupture is the most frequent cause of thrombosis. In plaque rupture, a structural defect—a gap—in the fibrous cap exposes the highly thrombogenic core to the blood (Figures 2 and 3). Dislodged plaque material is sometimes found within the thrombus, indicating that rupture and thrombosis coincided and thereby supporting its causal relationship. Plaque rupture is a well-defined term, described in a consensus statement from 2004,87 whereas other terms, such as plaque disruption and fissuring, are used ambiguously in the literature

Dr. Larson was called by Dr. Bellafiore and did not believe that Mr. Manning had suffered a dissection due to plaque, but had a plaque buildup on his artery.

Blocked artery. A blockage in the artery can happen if the plaque tears or ruptures. This rupture exposes the cholesterol and tissue that was under the fibrous cap.
