Almost all MIs are caused by rupture of coronary atherosclerotic plaques with superimposed coronary thrombosis. (medscape.com)
For example, it has become clear in the last decade that the biology of coronary atherosclerotic lesions is of more importance than the extent of stenosis in triggering acute vascular events. (abcdocz.com)
This is often caused by a sudden rupture of an atherosclerotic plaque and the subsequent thrombus formation, which results in an abrupt reduction, or complete cessation, of blood flow within the coronary artery. (unboundmedicine.com)
The death certificate and autopsy, completed and performed by the Medical Examiner, listed "cardiac dysrhythmia" due to "atherosclerotic coronary artery disease" as the immediate cause of death and "superimposed physical exertion" as a contributing factor. (cdc.gov)
Atherosclerotic plaques classically rupture and lead to thrombosis, contributing to acutely decreased blood flow in the coronary. (statpearls.com)
