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.

Inclusion Criteria:

• Acute ischemic stroke or transient ischemic attack of anterior circulation
• Consent of patient

Exclusion Criteria:

• primary intracranial hemorrhage,
• venous sinus thrombosis,
• unconsciousness,
• intubation,
• inability to provide and write a consent application form.

Patients attending to hospital settings diagnosed with acute ischemic event (stroke or TIA) and control group individuals undergo computed tomography (CT) or magnetic resonance imaging (MRI) of the brain, lipid profile, had stroke risk factors assessed.
