Brief 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.

Condition or disease Intervention/treatment Phase
Stroke Atrial Fibrillation Drug: 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. Phase 4

Detailed 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.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Non-vitamin K oral anticoagulant (NOAC)
Patients allocated to the NOAC arm will receive oral anticoagulation for 24 months, unless the patient is discontinued for procedures with increased risk of bleeding, adverse events, low creatinine clearance, or patient decision.
 Drug: 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.
Daily administration from time of randomization to final follow-up
No Intervention: No anticoagulation
Patients allocated to the no anticoagulation arm are not allowed to receive oral anticoagulation, unless the patient develops an indication for its use during follow-up.

Other Outcome Measures:
  1. Safety objective: incidence of composite of life-threatening, major, and critical organ bleeding [ Time Frame: Up to 24 months, until final follow-up ]
    as previously used in the MANAGE trial
