Criteria for diagnosis of coronary embolism (Shibata et al.).

Criteria for diagnosis of coronary embolism
Major criteria
Evidence of coronary embolism or thrombus angiographically without atherosclerosis.
Evidence of coronary emboli to multiple sites concomitantly.
Systemic embolization in the absence of acute myocardial infarction induced left ventricular thrombus.
Minor criteria
Stenosis of nonculprit coronary artery < 25%.
Evidence of embolic sources based on noninvasive imaging.
Presence of risk factors for emboli, cardiomyopathy, rheumatic heart disease, prosthetic valve, PFO, atrial septal defect, history of cardiac surgery, infective endocarditis, or hypercoagulable state.

Patients with 2 or more major criteria, 1 major and 2 minor, or 3 minor criteria were considered to have a definite coronary embolus. Patients with 1 major and 1 minor or 2 minor criteria were considered to have a probable coronary embolus.
