Summary

This study will track 3,000 stroke patients in China who received clot-busting medication more than 4.5 hours after their symptoms began. Researchers want to see if this later treatment is still safe and helps reduce disability. The study is observational, meaning it simply watches what happens in real-world practice rather than assigning treatments.

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 registry could provide evidence that extending the time window for clot-busting drugs is safe and effective, potentially changing stroke treatment guidelines.
What could go wrong: This is an observational study, not a controlled trial, so results may be influenced by patient selection and other factors. It only includes patients who already received the treatment, so it cannot prove cause and effect.
