Subsequent to publication of the NINDS t-PA Stroke Study results, we sought to determine the proportion of patients eligible for and receiving intravenous tissue plasminogen activator (t-PA) at an active acute stroke treatment center. Over a 12-month period there were 185 stroke code activations. Of these, 134 involved patients with ischemic stroke, and 48 of these (36%) were potentially eligible for treatment with t-PA by the time criterion (i.e., interval from stroke onset to hospital presentation < 3 hours). Nine of the 48 potentially eligible patients (19%) and 9 of 134 ischemic stroke patients (7%) overall received t-PA. In our patient population only a small proportion of all patients with acute ischemic stroke presently are eligible for treatment with t-PA.
