Popis: Background Atrial fibrillation is a predictor of poor prognosis after stroke. Aims To evaluate atrial fibrillation and all-cause and cardiovascular mortality in a stroke cohort with low socioeconomic status, taking into consideration oral anticoagulant use during 12-year follow-up. Methods All-cause mortality was analyzed by Kaplan–Meier survival curve and Cox regression models to estimate hazard ratios and 95% confidence intervals (95% CI). For specific mortality causes, cumulative incidence functions were computed. A logit link function was used to calculate odds ratios (OR) with 95% CIs. Full models were adjusted by age, sex, oral anticoagulant use (as a time-dependent variable) and cardiovascular risk factors. Results Of 1121 ischemic stroke participants, 17.8% had atrial fibrillation. Overall, 654 deaths (58.3%) were observed. Survival rate was lower (median days, interquartile range-IQR) among those with atrial fibrillation (531, IQR: 46–2039) vs. non-atrial fibrillation (1808, IQR: 334–3301), p-log rank Conclusions Among individuals with low socioeconomic status, atrial fibrillation was an independent predictor of poor survival, increasing all-cause and cardiovascular mortality risk. Long-term oral anticoagulant use was associated with a markedly reduced risk of all-cause and stroke mortality.
