The Prevalence of a Low Ankle-Brachial Index in Acute Cerebral Ischemia.

The Prevalence of a Low Ankle-Brachial Index in Patients With Acute Cerebral Ischemic Event.

Aim of the study is assessment the prevalence of the low ankle-brachial index (ABI) defined less than or equal 0.9 in patients with acute cerebral ischemic event (stroke or transient ischemic attack) and determinate the correlation between ABI and internal carotid artery stenosis (ICAS) in the acute cerebral ischemic patients.

The low ABI is a strong marker of generalized atherosclerosis. LEAD is a strong independent predictor for stroke.

Aim of the study is assessment the prevalence of the low ankle-brachial index (ABI) defined less than or equal 0.9 in patients with acute cerebral ischemic event (stroke or transient ischemic attack) and determinate the correlation between ABI and internal carotid artery stenosis (ICAS) in the acute cerebral ischemic patients.

The ABI is a non-invasive tool useful for the diagnosis of LEAD. The low ABI is a strong marker of generalized atherosclerosis. LEAD is a strong independent predictor for stroke. Significant ICAS is prevalent among patients having LEAD. Acute ischemic stroke due to significant ICAS has poor prognosis.

Patients with LEAD may be a suitable subgroup for screening for ICAS using duplex scanning.

Estimating the relationship between cerebral ischemic event and the ABI value could help better guide preventive and risk reduction strategies.
