Benefits of tissue plasminogen activator
How much do patients benefit from tissue plasminogen activator?
Eight stroke patients need to be treated with IV tPA to give one patient a complete or near-complete recovery, and this number-needed-to-treat (NNT) takes into account the increased risk of hemorrhage after tPA administration.
Patients of any age benefit from tPA: recent studies suggest that those >80 years may benefit more than younger patients.
