Patients
with atrial fibrillation (AF) are at high risk for poor outcomes after receipt
of recombinant tissue plasminogen activator (rtPA) for acute stroke,
particularly if they have had the arrhythmia for a long time, research
suggests.
"This
information is useful to identify stroke patients at higher risk for adverse
stroke outcomes following rtPA treatment who may benefit from closer blood
pressure control and monitoring and, perhaps, early endovascular
treatment," says Raymond Seet (Mayo Clinic, Rochester, Minn.) and team.
Patients
with a first-ever AF episode did not appear to be at increased risk for poor
outcomes, although the researchers note that they could not distinguish between
patients with a genuine first episode and those who may have had undiagnosed
paroxysmal AF.
