Atrial fibrillation (AF) is a common cardiac rhythm disorder which poses a significant risk for cerebrovascular morbidity and mortality. 1 When used appropriately, oral anticoagulants (OACs) have shown to reduce the incidence of embolic stroke in AF by more than 50%. 2 Vitamin K antagonists (VKA...

Aims Oral anticoagulants (OACs) are considered the mainstay in preventing stroke in atrial fibrillation (AF). OAC treatment remains suboptimal among AF patients, even after the introduction of direct oral anticoagulants (DOACs). We aimed to assess trends overtime and current implementation of OAC t...

Background: Existing data regarding the link between COVID-19 vaccine and myasthenia gravis (MG) are scarce. We aimed to assess the association between Pfizer-BioNTech vaccine with both new-onset MG and MG exacerbation. Methods: For the first aim, we conducted a nested case-control study in a co...

OAC treatment remains suboptimal among AF patients, even after the introduction of direct oral anticoagulants (DOACs). We aimed to assess trends overtime and current implementation of OAC tr...

Background: Adherence to direct oral anticoagulants (DOACs) remains a concern among non-valvular atrial fibrillation (AF) patients. We aimed to assess patterns of adherence with DOACs and examine their association with ischemic stroke and systemic embolism (SE). Methods: This retrospective cohor...
