Hemorrhagic infarction on CT in cardioembolic stroke

Area of Science:

• Neurology
• Radiology
• Cardiology

Background:

• Cardioembolic stroke necessitates prompt management, often involving anticoagulation.
• Computed tomography (CT) is crucial for diagnosing stroke and guiding treatment.
• The risk of hemorrhagic transformation during anticoagulation requires careful assessment.

Purpose of the Study:

• To evaluate the utility of CT scans in patients with cardioembolic stroke undergoing anticoagulation.
• To determine the incidence of hemorrhagic infarction in patients treated with anticoagulants.
• To assess the role of CT in risk stratification for early anticoagulant therapy.

Main Methods:

• Retrospective analysis of CT scans from 103 patients with cardioembolic stroke.
• Data collected from a prospective registry focusing on early anticoagulant treatment risks.
• CT scans reviewed for infarction and hemorrhagic transformation, including initial and follow-up imaging.

Main Results:

• 66 out of 103 CT scans (64%) showed infarction.
• Initial CT revealed hemorrhagic infarcts in 5% of patients.
• Follow-up CT in 35 patients showed hemorrhagic infarction in 17%, without clinical worsening.

Conclusions:

• Hemorrhagic infarction on CT does not definitively indicate a cardioembolic stroke origin.
• CT imaging is valuable in assessing risks associated with early anticoagulant treatment in cardioembolic stroke.
• Careful interpretation of CT findings is essential for safe and effective anticoagulation management.
