[Validation of the ABCDI and ABCD2I scales in the registry of patients with transient ischemic attacks from Lleida (REGITELL) Spain].
OBJECTIVE
A new radiological-clinical score (ABCDI) has been recently described to predict the risk of stroke recurrence after a transient ischemic attack (TIA). We validated this score in a cohort of patients with TIA (REGITELL).


METHODS
We studied 310 consecutive patients with TIA. Clinical scales (ABCD and ABCD2) and radiological-clinical scales (ABCDI and ABCD2I) were quantified. Radiological clinical scales were calculated by adding one point for the presence of ischemic brain injury in CT scan to its eponymous clinical score. We established its relationship with the risk of recurrence at 7 and 90 days, and the presence of an atheromatous etiology (AE).


RESULTS
During the first week of follow-up, 18 (5.8%) patients suffered a recurrence, whereas 24 (7.7%) had a recurrence at 90 days. The multivariate study (Cox regression) identified the recurrence of episodes (hazard ratio [HR] 2.92, 95% CI 1.11 to 7.64, p=0.029) and AE (HR 3.13 95% CI: 1.17 to 8.36, p=0.023) as independent predictors of new stroke at 7 days and only AE for stroke at three months (RR 3.33, 95% CI: 1,42-7,77, p=0.006). The predictors (logistic regression) of AE were recurrence of episodes (odds ratio [OR] 3.12, 95% CI 1.58-6.14, p=0.001) and presence of ischemic lesions on CT scan (OR 2.69, 1.38-5.28, p=0.004).


CONCLUSIONS
The ABCDI and ABCD2I scales are not useful in our population. The risk of recurrence after a TIA cannot only be established by clinical scores or CT scan findings.
