Abstract
INTRODUCTION.Minor stroke refers to an ischemic vascular event that start with discrete symptoms. It has been suggested that these patients may have an unfavorable clinical outcome.
AIM.To evaluate the functional outcome at 90 days in patients with minor ischemic stroke in two hospitals in Bucaramanga, between 2015 and 2017.
METHODS.Cohort study in patients with acute ischemic stroke and NIHSS ? 5 points. An unfavorable clinical outcome was measured according to the modified Rankin Scale as ? 3 points. A bivariate analysis was performed through simple binomial regression models adjusted for age and sex. A p-value <0.05 was considered statistically significant.
RESULTS.90 patients were included (Aged 66.6 ± 13.5 years, 49 males (54%); 23 (36,5%) presented a modified Rankin score of 3-6 points. A history of diabetes (RR: 2.50 CI 95%: 1.33-4.70) and a modified Rankin score of 2 points prior to the event (RR 2.12 CI 95%: 1.39-3.24) were independently associated with significant disability
CONCLUSION.A previously compromised functional state, added to the endothelial dysfunction generated by diabetes mellitus, contribute significantly to an unfavorable outcome in patients with minor stroke.
