OBJECTIVES: To determine whether patients undergoing carotid endarterectomy (CE) for symptomatic left internal carotid artery (LICA) stenosis have greater risk of cognitive decline than patients with asymptomatic LICA disease or right internal carotid artery (RICA) disease. DESIGN: Observational. SETTING: Vascular surgery day hospital. PARTICIPANTS: The analysis included 103 patients (mean age 72.6+/-7.0, 73 men), of whom 50 had LICA disease (29 symptomatic). MEASUREMENTS: Cognitive function was evaluated (age- and education-adjusted Mini-Mental State Examination (MMSE), and Clock tests (CLOX1 and 2)) at baseline and at the end of the study period (average follow-up+/-standard deviation 44.4+/-14.3 months) in a sample of patients aged 65 and older, free from cognitive impairment, consecutively undergoing CE. RESULTS: At the end of the study period, MMSE, CLOX1, and CLOX2 scores were significantly lower in patients with symptomatic LICA disease (P<.001, P<.001, and P=.002, respectively) and not in the other groups of patients. Patients with symptomatic LICA disease had greater risk of cognitive decline than other individuals according to MMSE score (F=5.18, P=.002) or CLOX1 and 2 scores (F=5.66, P=.001, and F=4.33, P=.006, respectively). CONCLUSION: Patients undergoing CE for symptomatic LICA disease appear to be at greater risk of cognitive decline than other subjects. These findings suggest that future studies should evaluate the effects on cognitive function of different timing for CE in patients with LICA and RICA disease.
