Anticoagulation for Stroke Prevention In Patients With Recent Episodes of Atrial Fibrillation Occurring Transiently With Stress
Sponsored by Population Health Research Institute
About this study
Multinational, investigator-initiated study of oral anticoagulation versus no anticoagulation for the prevention of stroke and other adverse cardiovascular events in patients with transient atrial fibrillation occurring transiently with stress and additional stroke risk factors.
ASPIRE-AF is a prospective, randomized, open-label trial of non-vitamin K oral anticoagulants (NOACs) versus no oral anticoagulation in patients with transient atrial fibrillation and additional stroke factors occurring transiently with stress. The primary objective is to assess the effects of NOACs versus no anticoagulation on the co-primary composite outcomes of 1. non-hemorrhagic stroke and systemic embolism, and 2. vascular mortality, and non-fatal non-hemorrhagic stroke, myocardial infarction, peripheral arterial thrombosis, amputation, and symptomatic venous thromboembolism over the duration of follow-up.
