Clinical Trial 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.


Clinical Trial Description

ASPIRE-AF is a prospective, randomized, open-label trial of non-vitamin K oral anticoagulants (NOACs) versus no oral anticoagulation in patients with transient perioperative atrial fibrillation and additional stroke factors after noncardiac surgery. 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. ;
