Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18-65 who have suffered an acute anterior STEMI and have severe left ventricular dysfunction.
✕Probably not a fit
Patients with a history of previous myocardial infarction, advanced chronic kidney disease, or those requiring chronic anticoagulation may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This clinical trial aims to evaluate the safety and efficacy of low-dose Apixaban (2.5 mg twice daily) in preventing left ventricular thrombus formation in patients who have experienced an acute anterior myocardial infarction with severe left ventricular dysfunction. Participants will be randomly assigned to receive either Apixaban in addition to standard medical therapy or standard therapy alone. The study will follow patients for four weeks post-treatment to assess the incidence of thrombus formation. Eligible patients are those aged 18-65 with specific heart function criteria and without existing thrombus.
Why it matters
Potential benefit: If successful, this treatment could significantly reduce the risk of thrombus formation in patients recovering from severe heart attacks.
How similar studies have gone: While the use of Apixaban in this specific context is novel, similar studies have shown promise in anticoagulation for thrombus prevention in other settings.
