Sex-Specific Risk Factors of Nonstenotic Carotid Plaque in Embolic Stroke of Unknown Source: A Case-Control Study.

Background: Many ischemic strokes are diagnosed as embolic strokes of undetermined source (ESUS). Recent evidence suggests that nonstenotic carotid plaque (nsCP) may be a substantial contributor to the risk for ESUS. We aimed to investigate the risk factor profile associated with nsCP in ESUS and defined stroke etiologies.
