While current guidelines support the use of direct oral anticoagulants (DOACs) as alternatives to vitamin K antagonists (VKA), their benefit across different aetiologies remains uncertain. This study aimed to compare the efficacy and safety of DOAC vs. VKA across different aetiologies of LV dysfunction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>We conducted a multi-centre observational study including 901 patients with confirmed LV thrombus treated with either a VKA or DOAC. The primary outcome was thrombus resolution, secondary outcomes included stroke and systemic embolization (SSE), major bleeding and mortality with analyses performed by aetiology. The principal aetiologies were AMI (38.3%), ischaemic cardiomyopathy (ICM) (38.0%) and non-ischaemic cardiomyopathy (NICM) (23.7%). Overall, thrombus resolution was significantly higher in DOAC treated patients, but this was driven by the AMI sub-group (P = 0.018). Direct oral anticoagulant use independently predicted thrombus resolution (OR 2.0, 95% Cl 1.29\u20133.24, P = 0.010). Major bleeding events (BARC \u22653) were more common with VKA use (P = 0.008). Non-ischaemic cardiomyopathy had the highest SSE rate (15.3%, P = 0.002), which were significantly raised in those treated with DOAC (P &amp;lt; 0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The underlying aetiology of LV dysfunction significantly influences both treatment response and outcomes in patients with LV thrombus. Direct oral anticoagulant were associated with superior efficacy and safety in AMI-related LV thrombus, but were linked to increased rates of SSE in NICM. These findings highlight the importance of aetiology on LV thrombus management and the potential need for tailored approaches.<\/jats:p>\n
