Patients with symptomatic carotid artery stenosis show reduced cerebral blood flow during the Valsalva maneuver, leading to concerns about stroke risk.
Cerebral blood flow decreased by 0.80 ± 0.04 in patients compared to 0.96 ± 0.05 in controls (p < 0.05), indicating impaired hemodynamic function.
Assessment included heart rate variability, active stand test, and Valsalva maneuver to evaluate autonomic and hemodynamic functions.
Despite findings of altered cerebrovascular hemodynamics, significant autonomic dysfunction was not detected in the patient group.
