Only minor or rapidly improving stroke symptoms(clearing spontaneously and without disabling deficits).

The scientific rationale for choosing such a restrictive time window was from the original NINDS trials came from models of ischemic Bibliography Demearschalk, B.M., et al. (2015). Scientific rational for the inclusion and exclusion criteria for intravenous altplase in acute ischemic stroke: A statement for healthcare professionals from the American Heart Association/American Stroke Association. The exclusion criteria for the administration of IV tPA were largely dictated by the exclusion criteria chosen by the investigators in the original NINDS trial. Since 1995, data suggests that IV tPA may hold benefit for subsets of patients with traditional exclusion criteria. Because it is outside the window of the ideal time frame for therapy, there are additional (and more restrictive) exclusion criteria, including being over the age of 80, having a severe stroke, and having a history of diabetes prior to having a stroke.

INCLUSION CRITERIA: All must be YES at time of evaluation to be eligible for thrombolysis. Yes No Age 18 years or older Yes No Clinical diagnosis of ischemic stroke with measurable neurologic deficit Yes No Clearly defined time of stroke onset (last seen well) within 4.5 hours EXCLUSION CRITERIA:

Absolute Contraindications within 3 hour (180 minute) window: Yes No Cannot be treated within 3 to 4.5 hour window (If greater than 3 hours see additional criteria) Although the risk of intracerebral haemorrhage is higher in elderly patients, the use of iv r-tPA is recommended in patients over 80 years old unless there are other exclusion criteria (27, 28). tPA Exclusion Criteria You have appropriately identified that the patient likely is suffering from an acute stroke and is a potential tPA candidate.

This will allow us to better inform stroke providers of quantitative and qualitative risks In patients in the 0‐4.5 hour time window who meet criteria for treatment with IV TPA substantially delaying intravenous alteplase to obtain penumbra imaging before treatment is not recommended (Class III; level evidence C) The new AHA/ASA statement on the rationale for tPA inclusion and exclusion criteria is meant to serve as a guideline for practitioners to maximize the benefit of thrombolysis in stroke patients. The statement places a strong emphasis on ensuring that the therapeutic benefit of tPA outweighs its risks.
