Clinical Question

Can use of fibrinolytics for acute ischemic stroke be extended to a wider range of patients up to 6 hours?

Conclusion

Thrombolysis within 6 hours improved functional outcome even though there were early hazards. This applies to the population of patients recruited for IST-3, benefits appear to be seen in the elderly as well.

Study Design

• International, randomized controlled trial
• open treatment

Inclusion Criteria

• Signs and symptoms of acute stroke
• Known time of stroke onset
• Treatment could be started within 6 hours of onset
• CT or MRI excluded ICH and brain lesion
• Patient and clinician felt the treatment was "promising but unproven"
• If patient had indication for IV thrombolysis- treated with local guidelines
