Total Bolus Transit Time Predicts Cardiac Dysfunction in Acute Ischemic Stroke and Transient Ischemic Attack Patients: A Retrospective Double Center Study.

Key Result

Bolus tracking during CTA reliably identifies heart failure and cardioembolic stroke, enabling faster diagnosis and better investigation selection in acute stroke/TIA patients.

Key Points

This study aims to determine if total bolus transit time can predict cardiac dysfunction in patients with acute ischemic stroke or transient ischemic attack.
Retrospective analysis conducted in two centers
Used bolus tracking during CTA for evaluation
Monitored patients with acute ischemic stroke and transient ischemic attack
Total bolus transit time was effective in predicting cardiac dysfunction
Facilitated quicker diagnosis for heart failure and cardioembolic stroke
Enhanced selection of further diagnostic investigations in the emergency setting

Structured PICO

Does total bolus transit time during CTA predict cardiac dysfunction in acute ischemic stroke and transient ischemic attack patients?

Population

Acute ischemic stroke and transient ischemic attack patients

Intervention

Total bolus transit time measurement via bolus tracking during computed tomography angiography (CTA)

Outcome

Identification of cardiac dysfunction (heart failure and cardioembolic stroke)surrogate

Total bolus transit time during CTA is a reliable tool for identifying heart failure and cardioembolic stroke in acute stroke/TIA patients, facilitating faster diagnostic workup.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

Bolus tracking during CTA provides a reliable and easily accessible radiological tool for the identification of heart failure and cardioembolic stroke, enabling a faster diagnostic workup and facilitating appropriate selection of further diagnostic investigations within the acute emergency setting.
