Abstract
Introduction and Purpose: Our aim was to review the characteristics of transient ischemic attack (TIA) and minor ischemic stroke patients monitored for atrial fibrillation (AF) epidoses detection within the first 4weeks after stroke to assess AF predictors. Materials and Methods: TIA and minor ischemic stroke patients (nihss≤ 5) were selected from CRYPTO-AF database. CRYPTO-AF is a prospective multicentre registry of patients with cryptogenic stroke older of 55 year-old. Monitoring started within the first 72 hours from stroke symptoms onset and was prolonged for 4 weeks. Clinical, cardiographic and blood test parameters of patients included were reviewed. Fisher exact and Mann Whitney tests were used to analyze categorical and continuous data. Results: In our cohort of 152 transient and minor ischemic stroke patients, 55.9% were men, mean age 73.18±10.24 and median NIHSS score was 2.31(0-5). A total of 30 patients (20.3%) were diagnosed with AF in the first month of monitoring, 6 patients (5.7%) within the first 3 days, 14 patients (13.3%) between 3 days and to 2 weeks of monitoring, and 14 partientes (12.4%) between the second and the fourth week. In these transient and minor ischemic stroke patients, age (p< 0.031), left atrial volume index (p< 0.023), the appearance of isolated extrasystoles during monitoring (p< 0.021), Type B natriuretic peptide (p< 0.011) and the longitudinal strain (p< 0.019) appeared as independet precitors of AF. However in the multivariate analysis adjusted for the above variables, only left atrial strain (OR 0.89, 95% CI: 0.797-0.991, p< 0.034) independently predicts AF detection. Conclusions: In our serie, only the left atrial strain appeared as a indepent predictor of AF. Given the known pathophysiology of TIA and minor ischemic stroke, the description of AF predictors would help to identify those patients who would benefit from completing a longer monitoring. More studies are needed to identify these predictors.
