Asymptomatic carotid stenosis may not elevate stroke risk in older men; leaves open whether ABI screening refines cerebrovascular risk stratification.
Does asymptomatic carotid stenosis increase the risk of stroke, transient ischaemic attack, and all-cause mortality in 68-year-old men?
In 68-year-old men, asymptomatic carotid stenosis was not associated with an increased risk of stroke, whereas asymptomatic leg artery disease (ABI <0.9) strongly predicted future cerebrovascular events.
Hedblad et al. (1995) studied this question.
