A clinical investigation finds microembolic signals correlate with ongoing embolization in acute ischemic stroke, suggesting new diagnostic avenues.
MES were detected in one-sixth of anterior circulation AIS patients, but were absent in lacunar stroke. Their presence was associated with multiple-territory infarcts, newly detected atrial fibrillation, and cancer-related stroke. MES counts correlated with D-dimer levels, supporting their role as markers of ongoing cerebral embolization and underlying prothrombotic state, with potential utility in revealing occult embolic mechanisms.
