Eligibility Criteria
Inclusion
- Age: 18 through 80 years (i.e., candidates must have had their 18th birthday, but not had their 81st birthday)

- An NIHSSS \>/= 10 at the time that intravenous rt-PA is begun
Exclusion
- History of stroke in the past 3 months
- Previous intra-cranial hemorrhage, neoplasm, subarachnoid hemorrhage, or arteriovenous malformation
- Clinical presentation suggests a subarachnoid hemorrhage, even if initial CT scan is normal
- Hypertension at time of treatment; systolic BP \> 185 or diastolic \> 110 mm Hg) or aggressive measures to lower blood pressure to below these limits are needed.
- Presumed septic embolus
- Presumed pericarditis, including pericarditis after acute myocardial infarction
- Recent (within 30 days) surgery or biopsy of parenchymal organ

- Females of childbearing potential who are known to be pregnant and/or lactating or who have positive pregnancy tests on admission
- Baseline lab values: glucose \< 50mg/dl or \> 400mg/dl, platelets \<100,000, or Hct \<25
- Subjects that require hemodialysis or peritoneal dialysis
- Subjects who have received heparin within 48 hours must have a normal partial thromboplastin time (PTT) to be eligible
- Subjects with an arterial puncture at a non-compressible site or a lumbar puncture in the previous 7 days
- Subjects with a seizure at onset of stroke
- Subjects with a pre-existing neurological or psychiatric disease that would confound the neurological or functional evaluations
- Other serious, advanced, or terminal illness
- Any other condition that the investigator feels would pose a significant hazard to the subject if Activase (Alteplase) therapy is initiated
- Current participation in another research drug treatment protocol; subject cannot start another experimental agent until after 90 days
- Informed consent is not or cannot be obtained. For example, obtunded subjects are not automatically excluded from the study.
