Table 1. Vulnerable plaque and vulnerable patient features associated with stroke in ACS.

Vulnerable plaque	Vulnerable patient
80–99% stenosis	High systolic blood pressure
Plaque echolucency (GSM <25)	Smoking history of >10 pack-years
Plaque structural heterogeneity	Contralateral TIA’s or stroke
Juxta-luminal black area >8 mm2	Evidence of microembolization (TCD monitorization)
Thin-capped plaque with erosion/ulceration	Severe multivessel occlusive disease
Plaque with mobile flaps	Contralateral ICA occlusion
Progression of stenosis	Silent brain infarction in appropriate territory
Evidence of microembolization (TCD monitorization)
