BackgroundThe American Heart Association/American Stroke Association (AHA/ASA) recommended an expansion of the time window for acute ischemic stroke (AIS) reperfusion with intravenous (IV) recombinant tissue plasminogen activator (rt-PA) from 3 to 4.5 hours after symptom onset. We examine rates of IV and intra-arterial (IA) reperfusion before and after the recommendations to track guideline adoption in community practice.MethodsPatients with AIS in the Paul Coverdell National Acute Stroke Registry spanning years 2007-2012 were identified. Trends in rates of IV rt-PA versus IA therapy were examined. Outcomes included symptomatic intracerebral hemorrhage (sICH), in-hospital mortality, ability to ambulate at discharge, and discharge destination.ResultsFrom 2007 to 2012, there were 182,235 AIS patients (median age, 72 years; 51.5% women) in the database at the time of analysis. AIS patients receiving IV rt-PA increased significantly from 3.7% in 2007 to 5.1% in 2012 in the ≤3 hours time window and from .2% in 2007 to 1.3% in 2012 in the 3-4.5 hours time window (P < .001 for both). There was also a significant increase in the rate of IA therapy between 2007 and 2012 (P < .001). There was a significant decrease in the rate of sICH among patients who received any reperfusion between 2007 and 2012.ConclusionsThere was a trend for increased utilization of IV rt-PA in the 0-3 hours and the 3-4.5 hours time windows, which began around the same time as the publication of AHA/ASA recommendations in 2009. This increase was associated with an increase in IA treatment rates along with a decrease in overall sICH rates for patients receiving any reperfusion.
