Incidence of cardioembolic stroke related to atrial fibrillation in Joinville, Brazil
Abstract
Background: Atrial fibrillation (AF) is an important cause of cardioembolic stroke, and population aging has increased its prevalence.
Objective: To evaluate the incidence of cardioembolic stroke caused by AF in the city of Joinville, Brazil, as well as previous diagnoses and use of medication.
Methods: Between 2017 and 2020 we extracted data from the population-based Joinville Stroke Registry. Demographic characteristics, diagnosis of AF, and patterns of medication use were collected, and the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) system was used to classify the etiology.
Results: There were 3,303 cases of ischemic stroke, 593 of which were cardioembolic, and 360 had AF. Of the patients with AF, 258 (71.6%) had a previous diagnosis of the disease, and 102 (28.3%) were newly diagnosed after the stroke. Among patients with a previously-diagnosed AF, 170 (47.2%) were using anticoagulants, and 88 (24.4%) were using other medications.
Conclusion: During the analyzed period, ischemic stroke caused by AF was a significant burden on the population of Joinville, and a considerable number of patients had undiagnosed or untreated AF.
Antecedentes: A fibrilação atrial (FA) é uma importante causa de acidente vascular cebebral (AVC) cardioembólico, e o envelhecimento populacional aumentou a sua prevalência.
Objetivo: Avaliar a incidência de AVC cardioembólico causado por FA em Joinville, além dos diagnósticos prévios e do uso de medicamentos. MéTODOS: Entre 2017 e 2020, foram extraídos dados do registro de base populacional de AVC de Joinville. Características demográficas, diagnóstico de FA e padrões de uso de medicamentos foram coletados, e o sistema Trial of ORG 10172 in Acute Stroke Treatment (TOAST) foi utilizado para classificar a etiologia.
Resultados: Houve 3.303 casos de AVC isquêmico, sendo 593 cardioembólicos e 360 com FA. Dos pacientes com FA, 258 (71,6%) tinham diagnóstico prévio da doença, e 102 (28,3%) foram recém-diagnosticados após o AVC. Entre os pacientes com FA previamente diagnosticada, 170 (47,2%) estavam em uso de anticoagulante, e 88 (24,4%), em uso de outra medicação. CONCLUSãO: Durante o período analisado, o AVC isquêmico causado por FA foi um ônus significativo para a população de Joinville, e um número considerável de pacientes apresentava FA não diagnosticada ou não tratada.
