Summary
Brief summary (as posted)
Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. The aim of this study is to evaluate the efficacy of anticoagulation in patients with JAK2 mutation and gastroesophageal varices.
