The investigators aimed to design this randomized control trial to compare rivaroxaban and apixaban with warfarin in Left ventricular thrombus resolution by - Success rate of left ventricular thrombus resolution on follow up echocardiograms to be done at 1st, 3rd and 6th months after starting on these drugs. - Compare the adverse events of each drug in terms of major bleeding and stroke on follow up. Left ventricular thrombus (LVT) leads to thromboembolism in about 10-15% cases. Currently, guidelines recommended therapy for LVT is warfarin but treating LVT with warfarin is challenging due to - Its narrow therapeutic window. - Drug-drug and drug-food interaction. - Frequently tested International normalization ratio (INR) and cost effectiveness especially in low to middle income countries. In contrast Rivaroxaban and Apixaban has no drug-food or major drug-drug interaction and moreover it doesn't require frequent checks on INR and that's the reason Rivaroxaban and apixaban use in LVT is gaining traction over time but there is paucity of data both nationally and internationally. So further studies are required to evaluate the efficacy and safety of rivaroxaban and apixaban in comparison to warfarin in LVT, especially in low to middle income countries.
Contemporary data are lacking regarding the management of left ventricular thrombus (LVT) developed after ST segment elevation myocardial infarction
Introduction: The prevalence of left ventricular(LV) thrombus after acute myocardial infarction has decreased with thrombolysis and primary angioplasty intervention worldwide. However, most of the patients in our country present late after the onset of ischemia resulting in a comparable increase proportion of late presentation MI compared to developed countries. This delayed presentation is associated with the increased incidence of LV thrombus, associated with increased cerebrovascular and cardiovascular events resulting in increased morbidity and mortality. The Vitamin K Antagonist Warfarin is indicated in recent guidelines for the duration of 3-6 months. The use of Warfarin is less in our part of the world due to the requirement of frequent International Normalized Ration (INR) monitoring and dietary restrictions. Novel oral anticoagulants (NOACs) are an alternate option for such hindrance to the treatment of LV thrombus. This research will help assess the safety and efficacy of Rivaroxaban, one of the NOACs compared to warfarin. Objectives: Our aim will be to compare the efficacy of rivaroxaban compared to warfarin in the complete resolution of post-MI LV thrombus. The primary efficacy endpoint of our study will be a resolution of LV thrombus as assessed by cardiac MRI at the end of 3 months of the study period. The secondary endpoint will be the comparison of the safety of both drugs measured by the incidence of major bleeding and embolic events. Methods: The patients who present late after acute MI in our center with LV thrombus will be enrolled in our study. The diagnosis of LV thrombus will be diagnosed by cardiac MRI, which is considered the gold standard for the diagnosis. The patients then will be randomized in a 1:1 ratio to either warfarin or rivaroxaban within 24 hours of diagnosis of LV thrombus. The warfarin group will be prescribed the warfarin in the dose of 5mg daily and the dose titrated according to the INR value to maintain the INR range of 2 to 3. Rivaroxaban group will be prescribed 15 to 20mg according to the indication. The research group consisting of the principal investigator and coinvestigators will be responsible for the recruitment and overall study procedures.
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
Open label randomized controlled clinical trial to evaluate the efficacy and safety of apixaban versus warfarin in treating left ventricular thrombus in patients with acute or recent myocardial infarction (MI).
APERITIF is a prospective randomized open-label, blinded end-point (PROBE) trial, nested in the ongoing the "FRENCHIE" registry, a French multicenter prospective observational study granted by "ANR-RHU Grand Emprunt", in which all consecutive patients admitted within 48 hours after symptom onset in a cardiac Intensive Care Unit (ICU) for an acute myocardial infarction (AMI) are included (NCT04050956). Among them, eligible Patients for "APERITIF" will be randomized into two groups: Dual Anti-Platelet Therapy (DAPT) alone or DAPT plus rivaroxaban 2.5mg twice daily for 4 weeks, prescribed as soon as possible after admission and completion of the initial percutaneous coronary intervention/angiography procedure.
The left ventricular (LV) thrombus is an important complication of myocardial infarction (MI) and vitamin K antagonist (VKA) is the current recommended management therapy for these patients. However, lack of regular international normalized ratio (INR) monitoring, drug, and food interaction may leads to increased risk of over or under anticoagulation consequently compromising the effectiveness of the therapy. Hence, due to benefits like predictable dosing and lack of need for regular monitoring, use of non-vitamin K antagonist oral anticoagulants (NOACs) for these patients is increasing among cardiologists. However, clinical data for the justified use of NOACs in LV thrombus (LVT) are lacking and remained a point of debate among the cardiologists. A recently published Randomized Control Trial (RCT) by Abdelnabi M et al. namely the No-LVT trial, had established the safety of Rivaroxaban therapy in patient with post myocardial infarction (MI) LV thrombus along with promising efficacy. However, sample size of the study (n=79; 39 in Rivaroxaban and 40 Warfarin) was not sufficiently high enough to conclude efficacy of Rivaroxaban in these patients. Therefore, this open label RCT is designed with the primary objective to evaluate the efficacy of Rivaroxaban in resolution of post MI LV thrombus as compared to standard warfarin therapy at the interval of 1 month and 3 months to test the hypothesis that Rivaroxaban is safe and non-inferior in preventing thromboembolic and major bleeding events in these patients.
To investigate the predictive value of inflammatory indexes and CHA2DS2-VASc score for anterior myocardial infarction (ANT-MI) with left ventricular thrombus(LVT) (LVT).
Left ventricular thrombus is a recognised complication of acute myocardial infarction, associated with stroke, recurrent myocardial infarction and adverse cardiac remodelling. The prevention, treatment and resolution of thrombus is hampered by a lack of understanding of its initiation, propagation and dissolution. Advanced non-invasive imaging holds major promise in improving our understanding of the incidence and the natural history of left ventricular thrombus as well as providing potential biomarkers to assess disease activity and treatment efficacy. In this prospective observational study, the investigators will recruit patients with recent acute anterior myocardial infarction and screen them for evidence of left ventricular thrombus and subclinical stroke using hybrid positron emission tomography and magnetic resonance imaging (PET/MR). Each patient will undergo PET/MR of the heart and head 7±2 days after acute myocardial infarction. If left ventricular thrombus is present on baseline MR, patients will be started on anticoagulation at the discretion of the attending physician, who will determine the agent used (warfarin or direct oral anticoagulant) and the duration of therapy (3-6 months). Patients will then undergo repeat PET/MR at completion of anti-coagulant therapy and then again after another 3 months. Patients with increased 18F- GP1 activity but no overt thrombus on MR will undergo repeat PET/MR of the head and heart at 3 and 6 months to establish the natural history of this observation and its association with thromboembolism in the brain. They will not routinely receive anticoagulation given the exploratory nature of this study.
