Comparing blood thinners for patients with liver disease and irregular heartbeat
Official title: The Comparative Effectiveness and Safety of Oral Anticoagulants in Patients with Cirrhosis and Atrial Fibrillation
Funded at Brigham and Women's Hospital · NIH-11026362 · Data updated 2026-11-12
This study is looking at how well different blood thinners work and how safe they are for people who have both liver cirrhosis and atrial fibrillation, to help find the best treatment for those at risk of stroke.

Who could benefit from this research
✓Could help
Ideal candidates for this research are adults over 21 years old who have been diagnosed with both cirrhosis and atrial fibrillation.
✕Less likely to help
Patients without cirrhosis or atrial fibrillation may not benefit from this research.
What this research studies
This research investigates the effectiveness and safety of different oral anticoagulants (blood thinners) in patients who have both cirrhosis and atrial fibrillation. It aims to understand why many patients with these conditions are not receiving anticoagulation therapy despite their high risk of stroke. The study will analyze various anticoagulant options, including warfarin and direct oral anticoagulants, to determine the best treatment approach for this vulnerable population. By focusing on real-world data, the research seeks to provide insights that could improve patient care and outcomes.
Why it matters
Potential benefit: If successful, this research could lead to better treatment strategies that reduce the risk of stroke in patients with cirrhosis and atrial fibrillation.
How similar studies have gone: While there has been significant research on anticoagulants in the general population, this specific focus on patients with cirrhosis and atrial fibrillation is largely untested, making it a novel approach.
