plaque rupture

plaque rupture

The separation of a lipid-rich lesion from the wall of a blood vessel. The damage this does to the lining of a blood vessel triggers a cascade of events that result in blood clot formation within the vessel and its eventual obstruction. This is the immediate cause of acute myocardial infarction. Synonym: cap rupture
