Stiffness Parameter β of Cardioembolism Measured by Carotid Ultrasound Was Lower Than Other Stroke Subtypes

Background: We estimated the stiffness parameter β (β value), which is useful in the assessment of premature atherosclerosis, among patients with different subtypes of cerebral infarction (CI; eg, small-vessel occlusion, large-artery atherosclerosis, cardioembolism, and other determined and undetermined etiologies) to determine the clinical utility of the β value in classification of stroke patients into CI subtypes.Methods: Carotid ultrasonography (ALOKA ProSound SSD-alpha10) was performed in 31 CI patients and 38 control subjects, and the β value of the bilateral common carotid artery at 2.0 cm proximal to the bifurcation was measured using the echo-tracking method. The relationship between β value and age was examined, and the β value was compared among the different CI subtypes.Results: Positive β value correlated with age in control subjects (R = .69, P
