This study looks at whether a specific measurement of how your left atrium (the upper left chamber of your heart) is functioning can help identify why some people have unexplained strokes. Researchers will review ultrasound images of your heart that were already taken as part of your stroke evaluation to measure how well this heart chamber is contracting. By comparing people who had unexplained strokes with those who had strokes with known causes, the study aims to determine if this heart measurement could help doctors predict and prevent future strokes.
About one-third of ischemic strokes happen without doctors finding a clear cause, leaving patients without a targeted treatment plan. Recent research suggests that problems with the left atrium of the heart may happen before irregular heartbeats develop and may increase stroke risk on their own. If this heart measurement proves helpful, doctors could use it to identify high-risk patients earlier and offer preventive treatments like blood thinners, even without detecting an irregular heartbeat.

This is a retrospective study, which means researchers will review heart ultrasound images and medical records you already had as part of your stroke care—you will not need to undergo new procedures or visits. Researchers at the University of Pittsburgh and other participating centers will analyze your ultrasound images using specialized computer software to measure your heart chamber function, and they will collect information about your stroke, any follow-up appointments, and whether you develop irregular heartbeats or have another stroke in the future. All of your information will be kept private and de-identified before being analyzed.
