Comparing anticoagulants for treating left ventricular thrombus after heart attacks in Nepal
Official title: Comparison of Warfarin Versus Rivaroxaban in Management of Post-myocardial Infarction Left Ventricular Thrombus in a Tertiary Cardiac Center of Nepal: a Randomized Control Study.
Run by Shahid Gangalal National Heart Centre · NCT05794399 · Data updated 2026-11-12
This study is testing whether two blood-thinning medications, Rivaroxaban and Warfarin, can help people in Nepal with blood clots in the heart after a heart attack.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults over 18 years old who have been hospitalized with acute STEMI and confirmed left ventricular thrombus.
✕Probably not a fit
Patients with active bleeding risks, severe comorbidities, or those currently undergoing anticoagulation therapy may not benefit from this study.

What this trial studies
This clinical trial evaluates the safety and efficacy of two anticoagulants, Rivaroxaban and Warfarin, in patients diagnosed with left ventricular thrombus following an acute ST-Elevation Myocardial Infarction (STEMI) in Nepal. The study aims to address the challenges faced by patients who present late for treatment, which increases the risk of thrombus formation and subsequent complications. Participants will be monitored for outcomes related to thrombus resolution and any adverse events associated with the anticoagulant therapies. The trial will utilize cardiac MRI to confirm the presence of LV thrombus before randomization.
Why it matters
Potential benefit: If successful, this study could provide a more effective and accessible treatment option for patients with left ventricular thrombus, potentially reducing morbidity and mortality associated with myocardial infarction.
How similar studies have gone: Other studies have shown promising results with the use of novel oral anticoagulants in similar patient populations, suggesting potential for success in this approach.
