Podcast #412: tPa Mission Creep

Author: Aaron Lessen, MD

Educational Pearls:

• Patients with "minor" strokes with NIHSS 0 to 5 can still end up having poor long-term outcomes
• Recent study compared use of alteplase vs. aspirin for these patients and saw no difference in regards to favorable neurologic outcome at 90 days
• Study was ended early due to patient recruitment difficulties

Editor's note: though ended early, it is debatable whether even if appropriately powered there would have been an identifiable benefit
