Left Atrial Reservoir Strain as a Predictor of Cardioembolic Ischemic Stroke and Atrial Fibrillation

This retrospective study evaluated left atrial reservoir strain using echocardiography in 79 stroke/TIA patients without prior atrial fibrillation history to identify cardiac sources of emboli. Reduced reservoir strain was associated with cardioembolic stroke mechanisms and atrial fibrillation occurrence, suggesting it may aid in stroke risk stratification and AF detection.
