Estudos recentes revelaram diferen\u00e7as na FA entre v\u00e1rios grupos demogr\u00e1ficos, incluindo a popula\u00e7\u00e3o latino-americana.  Objetivos  Melhor compreender as poss\u00edveis disparidades na preval\u00eancia da FA e nas estrat\u00e9gias de tratamento na popula\u00e7\u00e3o brasileira por meio de dados de um registro prospectivo multic\u00eantrico de grande escala.  M\u00e9todos  O registro de FA da Rede D\u2019Or \u00e9 um estudo observacional prospectivo multic\u00eantrico que incluiu pacientes com idade \u2265 18 anos com FA atendidos no pronto-socorro de 32 hospitais terci\u00e1rios no Brasil. Os pacientes foram caracterizados de acordo com o sexo e outras caracter\u00edsticas basais e classificados de acordo com o uso pr\u00e9vio de anticoagulantes. Foi analisada a falta de uso de anticoagulantes em pacientes com indica\u00e7\u00f5es pr\u00e9vias. A signific\u00e2ncia estat\u00edstica foi estabelecida em 5%.  Resultados  Os dados do estudo foram provenientes de um total de 1.955 pacientes inscritos. O sexo masculino foi mais prevalente e os homens eram mais jovens que as mulheres. Devido ao aumento da preval\u00eancia de epis\u00f3dios anteriores de FA e a um escore CHA2DS2-VASc mais elevado, mais mulheres tiveram indica\u00e7\u00e3o de terapia anticoagulante; no entanto, uma propor\u00e7\u00e3o significativa n\u00e3o estava recebendo esse tratamento. Dos 29 \u00f3bitos intra-hospitalares, 15 pacientes tinham indica\u00e7\u00e3o pr\u00e9via para anticoagula\u00e7\u00e3o, mas apenas 3 estavam em uso de anticoagulantes.  Conclus\u00e3o  O presente estudo revelou diferen\u00e7as relacionadas ao sexo na popula\u00e7\u00e3o brasileira de pacientes com FA que s\u00e3o consistentes com tend\u00eancias em pa\u00edses de alta renda. A promo\u00e7\u00e3o de uma melhor implementa\u00e7\u00e3o de terapias anticoagulantes e antitromb\u00f3ticas para reduzir o risco de \u00f3bito e eventos tromboemb\u00f3licos entre mulheres com FA no Brasil \u00e9 crucial.<\/jats:p>","DOI":"10.36660\/abc.20240310","type":"journal-article","created":{"date-parts":[[2024,10,8]],"date-time":"2024-10-08T12:12:08Z","timestamp":1728389528000},"source":"Crossref","is-referenced-by-count":3,"title":["Falta de Uso de Anticoagulantes em Pacientes com Fibrila\u00e7\u00e3o Atrial e Risco Aumentado de Eventos Tromboemb\u00f3licos de Acordo com o Sexo: Insights de um Estudo Multic\u00eantrico Brasileiro"],"prefix":"10.36660","volume":"121","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0044-1311","authenticated-orcid":false,"given":"Emiliano","family":"Medei","sequence":"first","affiliation":[{"name":"Instituto D\u2019Or de Pesquisa e Ensino,  Brasil; Universidade Federal do Rio de Janeiro,  Brasil; Universidade Federal do Rio de Janeiro,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8587-7319","authenticated-orcid":false,"given":"Renata","family":"Moll-Bernardes","sequence":"additional","affiliation":[{"name":"Instituto D\u2019Or de Pesquisa e Ensino,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1144-9252","authenticated-orcid":false,"given":"Martha V.
