Efficacy and Safety of Low Dose Rivaroxaban in Patients With Anterior Myocardial Infarction
Study Details
Study Description
Brief Summary
Despite the use of guideline directed optimal medical therapy, 12% of patients with stable coronary heart disease and 18% of patients with recent acute coronary syndrome experience recurrent major adverse cardiovascular events 1. The risk of recurrent cardiovascular events may be related to persistent elevation of thrombin beyond the index event 2,3
which leads to progression of cardiovascular disease by inducing inflammation, endothelial dysfunction and thrombosis 4. In patients with coronary heart disease, vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs) have been explored as secondary prevention strategies and have shown cardiovascular benefits at the cost of higher bleeding events 5,6,7,8.
howeverLeft ventricular thrombus (LVT) usually appearswithin 1 month after ST-segment elevation myocardial infarction (STEMI) and mostlyforms after anterior STEMI.9,11Although the prevalenceof LVT after acute myocardial infarction hasdecreased dramatically in modern times due to the progress of reperfusion therapy, LVT incidence in patients with anterior STEMI remains at 4% to 26%.10,12 It complicates acute myocardial infarction and is associated with a higher incidence of poor outcomes.9
