Cerebral Autoregulation in Patients With Symptomatic Cerebral Atherosclerotic Stenosis

Recruiting now

Conditions studied: Cerebrovascular Stroke, Cerebral Artery Stenosis

In brief

In this multi-center prospective observational study within a cohort of symptomatic cerebral atherosclerotic stenosis (sCAS) patients, 850 subjects were planed to be enrolled to explore the relationship between cerebral autoregulation (CA) and stroke recurrence, determine the threshold values of CA parameter for predicting stroke recurrence associated with particular stenosis.
