Why the study?
Does an abnormal breath-holding index (≤0.89) predict short-term cognitive decline in subjects with asymptomatic carotid stenosis?
Population
548 subjects with asymptomatic carotid stenosis (ACS) who completed follow-up
Comparison
Abnormal cerebral vasomotor reactivity defined… vs Normal breath-holding index (BHI >0.89)
Design
Cohort

May support BHI-based risk stratification in asymptomatic carotid stenosis; hypothesis-generating and should not change practice without validation.
Does an abnormal breath-holding index (≤0.89) predict short-term cognitive decline in subjects with asymptomatic carotid stenosis?
A breath-holding index ≤0.89 on transcranial Doppler identifies patients with asymptomatic carotid stenosis at high risk for short-term cognitive decline.
Buratti et al. (2015) studied this question.
