The Applications and Influences of Transthoracic Echocardiography in Stroke Patients
An observational study of the Impact of Echocardiography on the Recurrence of Stroke, run by National Taiwan University Hospital at 1 site in Taiwan.
Trial summary
Transthoracic echocardiography (TTE) is known to be an effective modality in assessing cardiac function as well as the structure of the heart. It was estimated that between 15% and 30% of ischemic strokes were due to a cardioembolic source, Therefore, TTE has been assumed as an important screening tool in patients… Read more about this study

About this study
Transthoracic echocardiography (TTE) is known to be an effective modality in assessing cardiac function as well as the structure of the heart. It was estimated that between 15% and 30% of ischemic strokes were due to a cardioembolic source, Therefore, TTE has been assumed as an important screening tool in patients with ischemic stroke, as atrial fibrillation is one of the leading risk factors. However, current guidelines have little evidence in whether performing TTE can alter clinical management and prevent a future stroke. We aim to present the association of performing TTE and clinical outcomes in stroke patients.
What is being measured
The primary outcome is the main question the study is designed to answer.
recurrent stroke
