Microembolic Detection in Acute Ischemic Stroke Patients With Atrial Fibrillation and Outcome

Completed
Conditions
Infarction, Brain
Embolism
Atrial Fibrillation
Interventions
Other: The presence and rate of MES measured by TCD monitoring
Registration Number
NCT06018090
Lead Sponsor
Centro Hospitalar De São João, E.P.E.
Brief Summary

This multicenter international prospective cohort study will include patients with AIS with a known or newly diagnosed anticoagulant-naïve AF. All centers will use the same transcranial Doppler machine for one-hour monitoring with bilateral 2-MHz probes within 24 hours of symptom onset. Recordings will be analyzed for MES by a blinded central reader. The primary aim is to determine the proportion of patients with MES and the association of MES with functional outcomes assessed by a modified Rankin scale (mRS) score at 90 days.
