A new analysis of 8,993 people finds that those who had an ischemic stroke had significantly lower levels of a blood protein called ADAMTS13. This protein helps prevent blood clots. The difference was clear: stroke patients had much less of it than healthy people.
The study combined data from multiple earlier studies. It's what scientists call a meta-analysis. The results show a strong link between low ADAMTS13 and stroke. But this doesn't prove that low levels cause stroke. It could be that the stroke itself lowers the protein.
The researchers also looked at how ADAMTS13 might affect treatment. They checked if it influenced how well clot-busting drugs or clot-removal procedures worked. But the findings on that were mixed. Some studies said one thing, others said another. So it's not clear yet if ADAMTS13 matters for treatment success.
This is early evidence. More research is needed to understand if measuring ADAMTS13 could help predict stroke or guide treatment. For now, it's an interesting clue, not a proven tool.
Common questions
What is ADAMTS13?
ADAMTS13 is a protein in your blood that helps prevent blood clots from forming. It breaks down a large molecule called von Willebrand factor. When ADAMTS13 is low, clots are more likely to form, which can lead to a stroke.
Does low ADAMTS13 cause stroke?
This study found a link between low ADAMTS13 and ischemic stroke, but it doesn't prove cause and effect. It's possible that low levels contribute to stroke risk, or that the stroke itself lowers the protein. More research is needed.
Can I get tested for ADAMTS13?
ADAMTS13 testing is available but not routine. It's mainly used to diagnose a rare bleeding disorder called thrombotic thrombocytopenic purpura (TTP). This study suggests it might one day help assess stroke risk, but that's not ready for clinical use yet.
How does this affect stroke treatment?
The study looked at whether ADAMTS13 levels affect how well clot-busting drugs or clot removal work. The results were mixed and unclear. So for now, ADAMTS13 doesn't guide stroke treatment. Talk to your doctor about proven treatments.
