Predictors of Occult Atrial Fibrillation in 171 Patients With Cryptogenic TIA and Minor Stroke

Retrospective study, single-center, on 171 patients, presented a cryptogenic TIA and Minor stroke.

This study objective is to determine profitability of Holter 21 days for screening paroxystic ACFA / flutter in cryptogenic TIA/Minor stroke, and identify the predictive factors of discovery a paroxystic ACFA on Holter 21 days. Clinical and échocardiographics factors, and brain imaging (scanner and MRI) will be analyzed.

Inclusion Criteria:

• Cryptogenic TIA/Minor stroke
• Age > 18 years
• Medical care in Neuro Vascular Unit of CH Versailles
• Holter 21 days performed

Exclusion Criteria:

1. ACFA history
2. ECG or telemetry who showed ACFA before the Holter initializing
3. Carotid Stenosis / symptomatic vertebral
4. Arterial dissection
5. Prothrombotic state demonstrated by laboratory tests
6. Infective endocarditis
