BACKGROUND: Current guidelines recommend vitamin K antagonist (VKA) for left ventricular (LV) thrombus. This study aimed to compare the effectiveness and safety of direct oral anticoagulant (DOAC) and warfarin in Chinese patients with LV thrombus.
METHODS: Patients with LV thrombus admitted to Beijing Anzhen Hospital of Capital Medical University between January 2018 and January 2022, were enrolled in this cohort study. The primary endpoint was defined as thrombus resolution within 90 days. The secondary endpoints included thrombus resolution within 180 days, major bleeding events, and minor bleeding events. All patients were followed up for at least 90 days after diagnosis of LV thrombus. Patients were divided into the VKA and DOAC groups according to the anticoagulants. Differences in clinical endpoint events between the two groups were compared.
RESULTS: This study included 129 and 111 patients in the VKA and DOAC groups, respectively. After adjusting for gender and smoking status, no significant difference was observed in thrombus resolution within 90 days between the VKA and DOAC groups. Additionally, there was no difference between the two groups in the secondary endpoints of thrombus resolution within 180 days, major bleeding, and minor bleeding. In subgroup analysis, rivaroxaban and dabigatran did not show significant differences in primary and secondary endpoints.
CONCLUSIONS: This study showed no significant difference in thrombus resolution between DOAC and warfarin. DOAC might be an alternative to warfarin for the treatment of LV thrombus. However, further large prospective studies are required to explore the efficacy and safety of DOAC in patients with LV thrombus.
