A major research gap: The use of anticoagulants in cirrhosis.

ABSTRACT

Historically, anticoagulants were contraindicated in patients with cirrhosis owing to concerns about bleeding risks. However, recent studies have shown that patients with cirrhosis are not naturally anticoagulated and are at increased risk of prothrombotic events, such as portal venous thrombosis. In this article, we review preclinical and clinical data on the effects of anticoagulants in cirrhosis, including their potential benefits in reducing liver fibrosis, portal hypertension, and improving survival. Despite promising preclinical evidence, clinical translation has proven challenging. Nevertheless, we discuss the use of anticoagulation in specific clinical scenarios, such as patients with atrial fibrillation and portal vein thrombosis, and highlight the need for further research, including randomised-controlled trials, to determine the optimal role of anticoagulants in the management of patients with cirrhosis.
