Depends: This is a complex question. It depends on what percent of is already showing signs of infarction (dead brain) rather than just ischemia (brain at risk).... When we see > 1/3 of territory abnormal on initial ct scan, it is a contraindication for tpa (alteplase).
It also depends on how long the symptoms have been occurring.
But to answer your question, theoretically all could potentially benefit.
