If you have a minor stroke, which treatment works best? The answer may depend on what you care about most.
A new analysis of 26,176 patients with minor acute ischemic stroke (defined as NIHSS score 5 or less) compared 9 different blood-thinning treatments. The study used a method called network meta-analysis to rank treatments for different outcomes.
For the best chance of a full recovery (mRS score 0-1), single antiplatelet therapy (SAPT) ranked highest. For the best chance of living independently (mRS 0-2), aspirin came out on top. If you want rapid improvement within 24 hours, the clot-busting drug alteplase was most likely to help. To prevent a new stroke within 90 days, dual antiplatelet therapy (DAPT) was best. For reducing the risk of death, DAPT also ranked highest. And aspirin was linked to the lowest risk of bleeding in the brain.
But these findings come from a review of limited studies, not a large clinical trial. The authors say the results need to be confirmed in well-designed, large-scale studies before doctors change how they treat minor strokes.
Common questions
What is a minor acute ischemic stroke?
A minor stroke is one where symptoms are mild. In this study, it was defined as a score of 5 or less on the NIHSS scale, which measures stroke severity. These patients have a good chance of recovery but still need treatment to prevent another stroke.
Which treatment is best for preventing another stroke after a minor stroke?
According to this analysis, dual antiplatelet therapy (DAPT) was most likely to prevent a new ischemic stroke within 90 days. DAPT also ranked highest for reducing the risk of death. However, these results come from a review of limited studies and need more research.
Is aspirin or alteplase better for minor stroke?
It depends on your goal. Aspirin was best for achieving independence (mRS 0-2) and had the lowest risk of bleeding in the brain. Alteplase was best for early neurological improvement within 24 hours. Talk to your doctor about what matters most for you.
What are the risks of these treatments?
The study looked at symptomatic intracranial hemorrhage (bleeding in the brain) as a safety concern. Aspirin was associated with the lowest risk of this complication. Other side effects were not reported in this analysis. Always discuss risks with your healthcare provider.
