Impact of Abnormal Diffusion-Weighted Imaging Results on Short-term Outcome Following Transient Ischemic Attack
Why the study?
Is abnormal diffusion-weighted imaging (TSI) associated with a higher rate of in-hospital recurrent TIA or stroke compared to normal DWI or completed ischemic stroke?
Population
196 patients admitted to a university hospital between January 2003 and December 2004.
Comparison
Transient symptoms associated with infarction… vs TIA with normal DWI results, and completed…

Implication
May prompt closer monitoring in TSI-positive TIA; leaves open whether targeted interventions reduce recurrence.
Structured PICO
Is abnormal diffusion-weighted imaging (TSI) associated with a higher rate of in-hospital recurrent TIA or stroke compared to normal DWI or completed ischemic stroke?
P
Population
196 patients (146 with classic transient ischemic attack [TIA] and 50 with completed ischemic stroke [IS]) admitted to a university hospital between January 2003 and December 2004.
I
Intervention
Transient symptoms associated with infarction (TSI) defined as TIA with abnormal diffusion-weighted imaging (DWI) results.
C
Comparator
TIA with normal DWI results, and completed ischemic stroke (IS).
O
Outcome
In-hospital recurrent TIA or stroke.hard clinical
Transient symptoms associated with infarction (TSI) identifies a high-risk subgroup of TIA patients with a significantly greater rate of early recurrent TIA and stroke.
