Anticoagulação Crônica em Pacientes com Fibrilação Atrial e COVID-19: Uma Revisão Sistemática e Metanálise

Isabela Landsteiner,
Jonathan A. Pinheiro,
Nicole Felix
et al.

Abstract: Resumo Fundamento: A doença por coronavírus 2019 (COVID-19) está associada à hipercoagulabilidade. Permanece incerto se a anticoagulação contínua para fibrilação atrial (FA) em pacientes que posteriormente contraem COVID-19 melhora os desfechos clínicos. Objetivos: Comparar a anticoagulação oral crônica com ausência de anticoagulação prévia em pacientes com FA que contraíram uma infecção por COVID-19 em relação aos desfechos de mortalidade por todas as causas, mortalidade por COVID-19, admissão em unidade de… Show more

“…5 The regular use of oral anticoagulants (OAC) in patients with atrial fibrillation (AF), depending on their risk profile, has proven to have an impact on reducing thromboembolic stroke and mortality, being an indication enshrined in guidelines with a high degree of evidence. 6 The article by Landsteiner et al, 7 in this issue of the ABC Cardiol, seeks to answer what is the best approach for a patient with AF, who regularly uses OCP, and who is affected by COVID-19. The authors produce a careful meta-analysis aiming to find the answer regarding the risk versus benefit of using OAC in this clinical context.…”

“…However, one must take into account the major challenges to be overcome to produce a quality meta-analysis with the selection of studies to be included, identify potential biases, heterogeneity, quality of studies, incomplete data, reporting bias (publications only with favorable data), and the ability to generalize. 8 The authors 7 systematically searched PubMed, Embase, and Cochrane Library for eligible studies from the start of the pandemic until December 2022, including those that compared COVID-19 outcomes in patients with and without prior chronic oral anticoagulation for AF. The selection work used a rigorous protocol seeking publications with higher quality and less chance of bias, which is essential in the case of observational studies.…”
