Summary

Multinational, investigator-initiated study of oral anticoagulation versus no anticoagulation for the prevention of stroke and other adverse cardiovascular events in patients with transient perioperative atrial fibrillation after noncardiac surgery and additional stroke risk factors.

Description

ASPIRE-AF is a prospective, randomized, open-label trial to assess the effects of non-vitamin K oral anticoagulants (NOACs) versus no anticoagulation in patients with transient perioperative atrial fibrillation after noncardiac surgery and additional stroke risk factors. The primary objective is to assess the effects of non-vitamin K oral anticoagulants (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 24 months after randomization.

Details
Condition Stroke, Atrial Fibrillation
Treatment Investigators can choose from one of four Non-vitamin K oral anticoagulants (NOACs): Edoxaban 60mg daily, Apixaban 5mg twice daily, Dabigatran 110mg twice daily, or, Rivaroxaban 20mg daily.
