Abstract: Objective To evaluate the relationship between ambulatory arterial stiffness index (AASI) and intracranial and extracranial arterial stenosis in 146 patients with ischemic cerebrovascular disease. Methods Degree of intracranial and extracranial arterial stenosis in 146 patients with ischemic cerebrovascular disease was assessed by CT angiography (CTA). Then all patients were divided into 4 groups according to the numbers of branches with stenosis: no stenosis group, 1 branch group, 2 branches group, and 3 and more than 3 branches group. Dynamic blood pressure was monitored to calculate the AASI. Results There was no significant difference of AASI among the extracranial arterial stenosis groups (P=0.614). AASI was positively correlated with the degree of intracranial artery stenosis (r=0.743, P<0.05), and with 3 and more intracranial artery branches stenosis (r=0.797, P<0.05). Conclusion AASI is closely correlated with the degree and numbers of branches of intracranial artery stenosis.
