Abstract
The researchers assessed risk, incident, and prevalence of stroke during the 12-month period after TIA and examined whether the risk level and the ABCD2 score were associated with stroke event. We used retrospective data from TIA Registry, of the total 157 TIA patients who were admitted to a stroke care unit of the 750-bed tertiary care hospital, between December 2011 and September 2015. Data were analyzed using descriptive statistics and Fisher’s exact test. Using ABCD2 to stratify risk level revealed nearly a haft had low risk (47.77%), two-fifth in moderate risk (43.95%), 8.28% in high risk groups, and more than haft there are moderate to high risk (52.23%). Short-term incidence during 2-week, 4-week, and 3-month were 0%, 3.18%, and 3.18%. Long-term incidence during 12-month was 6.40%. Stroke prevalence after TIA at 3 and 12-month were 6.37% and 10.83%. The higher the score and the higher risk level on ABCD2 were significantly associated with the higher incident and prevalence of stroke in short-term. ABCD2 score should be added into routine assessment for patients with TIA to stratify, monitoring, and judgment for any appropriate treatment protocol.
