Key result
Comprehensive cardiovascular imaging demonstrated intraplaque hemorrhage in the culprit vessel of a patient who experienced sudden cardiac death resulting from coronary vasospasm.
Why the study?
Intraplaque hemorrhage is associated with plaque instability, sudden cardiac death, and coronary vasospasm, but demonstrating these associations with comprehensive cardiovascular imaging is informative.
Case Report (n=1)
No
This case report demonstrates the association between coronary vasospasm, intraplaque hemorrhage, and sudden cardiac death using comprehensive cardiovascular imaging.
Intraplaque hemorrhage may link vasospasm to MI arrest; hypothesis-generating, needs prospective confirmation before clinical implications.
Intraplaque hemorrhage is among the most important factors associated with plaque instability and atherosclerotic progression. It is also reported to be associated with cardiac sudden death and coronary vasospasm. We report the case of a patient with cardiopulmonary arrest caused by acute myocardial infarction secondary to coronary vasospasm where intraplaque hemorrhage was observed in the culprit vessel. This is an extremely important case report that demonstrates the associations among coronary vasospasm, intraplaque hemorrhage, and sudden cardiac death with comprehensive cardiovascular imaging.

Takasaki et al. (2025) conducted a case report in Sudden cardiac death resulting from coronary vasospasm (n=1). Intraplaque hemorrhage and coronary vasospasm was evaluated on Identification of intraplaque hemorrhage in the culprit vessel. Comprehensive cardiovascular imaging demonstrated intraplaque hemorrhage in the culprit vessel of a patient who experienced sudden cardiac death resulting from coronary vasospasm.
