Abstract:
The ABCD2
score is validated for evaluating short-term stroke risk after transient ischemic attack
(TIA); however, whether it is able to predict the long-term risk of vascular outcome remains uncertain.
Recently a new tissue-based definition of TIA has been proposed. The ABCD2
scores of 145 TIA
patients admitted to our hospital were retrospectively calculated and stratified into two categories:
≤ 3 points (low risk); 4-7 points (moderate-high risk). At a median follow-up of 81 months, new
vascular events were recorded. Follow-up data were available in 107 patients. Seventy one patients
had a moderate-high ABCD2
score. Sixty six patients experienced a cerebral ischemic event; 8 a
myocardial infarction; 7 died of cerebrovascular or cardiovascular cause. Moderate-high ABCD2
score
was significantly associated with the further cerebral ischemic events (hazard ratio [HR], 1.755; 95%
confidence interval [CI], 1.019 to 3.024) and with the combined endpoint (HR, 1.818; 95% CI, 1.079
to 3.063). Our study shows that the ABCD2
score may also be used to predict long-term vascular
outcome after tissue-based definition of TIA. Moderate-high ABCD2
score is associated with an
increased general vascular risk in the long-term follow-up after TIA.
