Abstract

BACKGROUND AND OBJECTIVE:

Recently a clinical score (ABCD) to identify individuals at high seven-day risk of stroke after transient ischemic attack (TIA) was proposed. The aim of this study was to test this clinical model.

PATIENTS AND METHOD:

We validated the ABCD score (age > or = 65 years = 1; hypertension = 1; unilateral weakness = 2, speech disturbance without weakness = 1, duration of symptoms in minutes > or = 60 = 2; 10-59 = 1; < 10 = 0) in 325 consecutive TIA patients. Clinical data, symptoms duration, CT scan, and ultrasonographic (carotid and transcranial) findings were collected. Seven-day risk of stroke was recorded.

RESULTS:

A total of 16 (4.9%) patients had a stroke recurrence within the first seven days after symptoms onset. Six out of 16 (37.5%) strokes occurred in 115 (35.4%) patients with a score of 5 or greater, while the 7-day risk was 4.8% (95% CI 2.04-7.56) in 210 (63.5%) patients with a score less than 5. In cox proportional hazards multivariate analyses only large-artery occlusive disease remained an independent predictor of stroke recurrence [hazard ratio = 5.66 (95% CI 2.06-15.57; p = 0.001)].

CONCLUSIONS:

Clinical data are not enough to identify patients at higher risk. The combination of clinical, radiological and vascular information may improve the predictive accuracy of stroke recurrence risk. The routine use of combined carotid/transcranial ultrasound testing performed early will be useful for identifying high risk individuals in order to plan urgent aggressive prevention therapies.
