Can low blood flow predict stroke? new study investigates
NCT ID NCT00590980
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study followed 82 people with blocked arteries supplying the back of the brain to see if low blood flow raises the risk of stroke or mini-stroke. Participants had already experienced a stroke or transient ischemic attack (TIA) and had at least 50% blockage in those arteries. Researchers used MRI to measure blood flow and tracked participants for future strokes. The goal was to determine if blood flow levels can help predict who is at highest risk.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this study could help doctors identify which patients with blocked brain arteries are at highest risk of stroke, leading to better prevention strategies.
What could go wrong
This is an observational study with only 82 participants, so results may not apply to everyone. It does not test a new treatment, so direct patient benefits are limited.
