Brief Summary
Objectives
- Primary: To test the hypothesis that apixaban is superior to aspirin for the prevention of recurrent stroke in patients with cryptogenic ischemic stroke and atrial cardiopathy.
- Secondary: To test the hypothesis that the relative efficacy of apixaban over aspirin increases with the severity of atrial cardiopathy.

Outcome Measures
Primary Outcomes (1)
Number of Participants With Recurrent Stroke of Any Type
Participants were monitored for up to 5 years of study participation. This is the number of participants who had recurrent stroke of any type (ischemic, hemorrhagic, or of unclear type).
Up to 5 years of study participation.
Secondary Outcomes (5)
Number of Participants With Recurrent Ischemic Stroke or Systemic Embolism
Up to 5 years of study participation.
Number of Participants With Recurrent Stroke of Any Type or Death From Any Cause
Up to 5 years of study participation.
Number of Participants With Symptomatic Intracranial Hemorrhage (Including Symptomatic Hemorrhagic Transformation of an Ischemic Stroke)
Through 30 days after permanent discontinuation of the study drug, a duration of up to 5 years for each participant.
Number of Participants With Major Hemorrhage Other Than Intracranial Hemorrhage.
Through 30 days after permanent discontinuation of the study drug, a duration of up to 5 years for each participant.
Number of Participant Deaths From Any Cause Number of Participants With All-cause Mortality.
Through 30 days after permanent discontinuation of the study drug, a duration of up to 5 years for each participant.
Study Arms (2)
Active agent: Apixaban
EXPERIMENTALPatients with a recent embolic stroke of undetermined source (ESUS) and evidence of atrial cardiopathy will receive Apixaban
Active control: Aspirin
ACTIVE COMPARATORPatients with a recent embolic stroke of undetermined source (ESUS) and evidence of atrial cardiopathy will receive Aspirin

Eligibility Criteria
You may qualify if:
- Age ≥ 45 years.
- Clinical diagnosis of ischemic stroke + brain imaging to rule out hemorrhagic stroke.
- Modified Rankin Scale (MRS) score ≤ 4.
- Ability to be randomized within 3 to 180 days after stroke onset.
- ESUS, defined as all of the following:
- Stroke detected by CT or MRI that is not lacunar. Lacunar is defined as a subcortical (this includes pons and midbrain) infarct in the distribution of the small, penetrating cerebral arteries whose largest dimension is ≤1.5 cm on CT or ≤2.0 cm on MRI diffusion images/\<1.5 cm on T2 weighted MR images. The following are not considered lacunes: multiple simultaneous small deep infarcts, lateral medullary infarcts, and cerebellar infarcts. Patients with a clinical lacunar stroke syndrome and no infarct on imaging are excluded.
- Absence of extracranial or intracranial atherosclerosis causing ≥50 percent luminal stenosis of the artery supplying the area of ischemia. Patients must undergo vascular imaging of the extracranial and intracranial vessels using either catheter angiography, CT angiogram (CTA), MR angiogram (MRA), or ultrasound, as considered appropriate by the treating physician and local principal investigator.
- No other specific cause of stroke identified, such as arteritis, dissection, migraine, vasospasm, drug abuse, or hypercoagulability. Special testing, such as toxicological screens, serological testing for syphilis, and tests for hypercoagulability, will be performed at the discretion of the treating physician and local principal investigator.
You may not qualify if:
- History of atrial fibrillation (AF), AF on 12-lead ECG, or any AF of any duration during heart-rhythm monitoring prior to randomization.
- Clear indication for treatment-dose anticoagulant therapy, such as venous thromboembolism or a mechanical heart valve.
- Need for antiplatelet agent, such as aspirin or clopidogrel
- History of spontaneous intracranial hemorrhage.
- Active hepatitis or hepatic insufficiency with Child-Pugh score B or C.
- Clinically significant bleeding diathesis.
- Unresolved anemia (hemoglobin \<9 g/dL) or thrombocytopenia (\<100 x 10E9/L).
- Clinically significant gastrointestinal bleeding within the past year (e.g., not due to external hemorrhoids).
- At risk for pregnancy: premenopausal or postmenopausal woman within 12 months of last menses without a negative pregnancy test or not committing to adequate birth control, which includes an oral contraceptive, two methods of barrier birth control such as condom with or without spermicidal lubricant + diaphragm, or abstinence.
- Known allergy or intolerance to aspirin or apixaban.
- Concomitant participation in another clinical trial involving a drug or acute stroke intervention.
- Considered by the investigator to have a condition that precludes follow-up or safe participation in the trial.
- Inability of either participant or surrogate to provide written, informed consent for trial participation.
- Atrial cardiopathy is defined as ≥1 of the following:
- PTFV1 \>5,000 μV\*ms on 12-lead ECG (ECG criterion).
- +2 more criteria
