Introduction: Transient ischemic attack (TIA) is an important risk factor for early ischemic stroke (IS) and is not well stablished  yet, the risk of recurrence in our population1,2. The North Dublin Population Stroke Study(9), had reported stroke recurrence of greater in patients with previous TIA than IS at 90 days, (13.45% vs. 5.72%, p = 0.002)3. Objective: To identify cerebrovascular risk factors previous to TIA and their relationship for recurrence of early stroke and final disability.
Methods: We retrospectively recorded clinical characteristics of 231 consecutive patients with recurrence of IS from a third care center between 1987 and 2017. We use SPSS 21.0v for statistical We performed bivariate analysis of unpaired proportions using the chi-squared test and Fisher's exact test. We compared continuous variables using the t test or the Mann Whitney U test as appropriate. We don't declare conflict of interest in this protocol. 
Results: A total of 231 patients with TIA diagnosis were included. We detected recurrence of ischemic stroke in 57 patients (25%), with a previous cerebrovascular risk factor of hypertension (OR: 2,94; 95% CI: 1,58-5,4), smoking (OR: 1,2; 95% CI: 1,0-1,55) and dyslipidemia (OR: 3,72; 95% CI: 1,8-7,4) all of them were stadistically significant. Favorable modified Rankin score  (mRS 0-2) was found in 39 (68%) patients. 
Conclusion: According to our results, as we already know the presence of TIA its a risk factor for recurrence of IS, nonetheless, we found that hypertension, smoking and dyslipidemia are independent risk factors for stroke recurrence among these patients. Further studies need to be done to stratify these risk factors and analyse if there’s necessary a more strict secondary prevention.
