Incidence and timing of stroke after TIA

In this prospective cohort of 488 patients with a TIA, 1%, 2%, and 5% had a stroke at 6, 12, and 24 hours, respectively. The ABCD2 score (link) correlated well with risk of stroke. Those with a score of 4 or less had a 2% risk of stroke at 24 hours, and those with a score of 7 or more had a 33% risk of stroke at 24 hours (abstract). This study highlights the need for urgent evaluation and risk stratification of patients with TIA symptoms.
