Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are patients who have suffered an acute ischemic stroke within the last 24 hours and have a baseline NIH Stroke Scale score of 4 or higher.
✕Probably not a fit
Patients with pre-existing severe disability or those who are not expected to remain hospitalized for at least 72 hours may not benefit from this study.

What this trial studies
This observational study aims to assess the impact of blood pressure variability (BPV) on functional and cognitive outcomes in patients who have experienced an acute ischemic stroke. It will investigate the association between BPV and patient outcomes, explore the underlying mechanisms of BPV's negative effects, and identify potential pharmacological treatments to reduce BPV. The study will enroll 150 patients with anterior circulation strokes and utilize advanced imaging techniques to validate findings and understand the relationship between BPV and stroke severity.
Why it matters
Potential benefit: If successful, this study could lead to improved treatment strategies for managing blood pressure variability in stroke patients, potentially enhancing recovery outcomes.
How similar studies have gone: Previous studies have indicated a correlation between blood pressure variability and adverse outcomes in stroke patients, but this study aims to provide a more standardized and prospective evaluation of this relationship.
