Direct oral anticoagulants (DOACs), are currently recognized as the first-line treatment of AF and VTE in most clinical scenarios, distinguished by their short half-life, fast onset of action, fewer medication interactions, rare food interactions, and the lack of a need for frequent laboratory monitoring, compared with vitamin K antagonists. Although the use of DOACs has earned a class III recommendation for patients with mechanical prosthetic valves, moderate-to-severe mitral stenosis, and antiphospholipid syndrome, their application in some situations, such as acute limb ischemia and LVT, remains uncertain. Until now, no completed randomized clinical trial has compared the efficacy and safety of left ventricle thrombosis in patients with acute STEMI and the existing evidence is limited to observational studies.
The purpose of the study is to assess the safety and efficacy of rivaroxaban-based versus warfarin-based antithrombotic regimens on outcomes of patients with left ventricle thrombosis following acute ST elevation myocardial infarction at 3 months from enrollment in an open-label parallel groups pilot randomized clinical trial
