Background. Carotid stenosis is an important cause of stroke. Carotid endarterectomy is a means of reducing the burden of stroke but is of marginal benefit in individuals with asymptomatic carotid stenosis. The identification of factors associated with increased risk of cerebral ischemic events would help select individuals who may obtain a greater benefit. / Methods. A comprehensive search was performed to identify studies examining risk factors for cerebral ischemic events in patients with asymptomatic carotid stenosis. Inclusion criteria were defined a priori. Relevant studies were reviewed, assessed for quality, and data were extracted. / Results. Thirty-four studies met the inclusion criteria. There was a suggestion of increasing neurological events with increasing severity and progression of carotid stenosis. There was some evidence for an association with carotid plaque morphology. No consistent association was found with clinical factors, impaired cerebral vasoreactivity, or cerebral embolic signals. / Conclusions. The evidence is insufficient to reliably identify individuals with asymptomatic carotid stenosis who are at a higher risk of cerebral ischemic events.
