Rivaroxaban versus aspirin

AIMS: Patients with coronary and peripheral artery disease (PAD) have a residual risk of major adverse cardiovascular and limb events despite standards of care. Among patients with coronary artery disease (CAD) and/or PAD selected for low dose rivaroxaban (2.5 mg BID) and aspirin, we sought to determine the highest risk vascular patients. METHODS: XATOA is a single-arm registry of CAD and/or PAD patients. All participants were initiated on low dose rivaroxaban (2...

INTRODUCTION: The successful management of wound healing following total hip arthroplasty (THA) is multifaceted, relying on various intraoperative techniques and surgical variables. Recent reviews have evaluated many of these factors, including the comparison between mesh-adhesive dressings and other skin closure methods, the closing time of different suture techniques, and the four aspects of closure for THA (deep fascial layer; subdermal layer; intradermal layer). However, previous articles did not cover certain topics that can be directly influenced by the surgeon...

BACKGROUND: Rivaroxaban 2.5 mg twice daily with aspirin 100 mg daily was shown to be better than aspirin 100 mg daily for preventing cardiovascular (CV) death, stroke or myocardial infarction in patients with either stable coronary artery disease (CAD) or peripheral artery disease (PAD). The cost-effectiveness of this regimen in this population is essential for decision-makers to know. METHODS: US direct healthcare system costs (in USD) were applied to hospitalized events, procedures and study drugs utilized by all patients...

BACKGROUND: A systematic review and network meta-analysis (NMA) were conducted to explore the efficacy and safety of different antiplatelet or anticoagulation drugs in chronic coronary syndromes patients. METHODS: Electronic databases (Pubmed, Embase and Cochrane databases) were systematically searched to identify randomized controlled trials evaluating different antiplatelet or anticoagulation drugs (aspirin, aspirin + clopidogrel, aspirin + clopidogrel + cilostazol, clopidogrel/prasugrel + aspirin, aspirin + rivaoxaban 2...

BACKGROUND: Rivaroxaban plus aspirin compared with aspirin alone reduced major cardiac and ischemic limb events after lower extremity revascularization (LER) in the VOYAGER PAD (Vascular Outcomes Study of ASA Along With Rivaroxaban in Endovascular or Surgical Limb Revascularization for Peripheral Artery Disease) trial. The effect has not been described in patients undergoing endovascular LER. METHODS: The VOYAGER PAD trial randomized 6564 patients with symptomatic peripheral artery disease to a double-blinded treatment with 2...

BACKGROUND AND AIMS: Systolic blood pressure interarm difference (IAD) predicts cardiovascular morbidity and mortality in primary prevention populations. We examined the predictive value of IAD and the effects of treatment with the combination of rivaroxaban 2.5 mg twice daily plus aspirin 100 mg once daily versus aspirin 100 mg once daily according to IAD in patients with chronic coronary artery disease or peripheral artery disease. METHODS: COMPASS trial patients with IAD <15 mmHg and IAD >15 mmHg were compared with respect to thirty-month incidence risk of: 1) composite of stroke, myocardial infarction, or cardiovascular death (MACE), 2) composite of acute limb-ischemia or vascular amputation (MALE), 3) composite of MACE or MALE, and 4) effects of treatment with the combination versus aspirin alone on these outcomes...

BACKGROUND: To compare the characteristics of a "real world" population included in a prospective registry to patients enrolled in a randomized, controlled trial (RCT) after endovascular revascularization (EVR) for symptomatic peripheral artery disease (PAD). METHODS: The RECcording COurses of vasculaR Diseases (RECCORD) registry is an observational registry prospectively recruiting patients undergoing EVR for symptomatic PAD in Germany. VOYAGER PAD was an RCT which demonstrated the superiority of rivaroxaban and aspirin versus aspirin to reduce major cardiac and ischemic limb events following infrainguinal revascularization for symptomatic PAD...

BACKGROUND: Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor is recommended for patients with coronary heart disease (CHD) undergoing percutaneous coronary intervention (PCI) to antithrombosis, meanwhile, increasing the risks of gastrointestinal bleeding. Rivaroxaban, a novel oral anticoagulant, combined with a P2Y12 receptor inhibitor reduces adverse events in patients with CHD and atrial fibrillation who underwent PCI. The effect of rivaroxaban plus P2Y12 inhibitor on reducing bleeding events in patients with CHD and gastrointestinal disease (GID) undergoing PCI remains unclear...

INTRODUCTION: In clinical trials, event adjudication is a process to review and confirm the accuracy of outcomes reported by site investigators. Despite efforts to automate the communication between a clinical-data-and-coordination center and an event adjudication committee, the review and confirmation of outcomes, as the core function of the process, still fully rely on human labor. To address this issue, we present an automated event adjudication system and its application in two randomized controlled trials...

INTRODUCTION: The evaluation and management of patients who sustain recurrent thromboembolic events while taking therapeutic anticoagulation have not been well characterized; moreover, there has been no systematic review or randomized trial focused on treating patients with recurrent deep vein thrombosis (DVT) and pulmonary embolism (PE) during anticoagulant treatment. Therefore, we developed a pilot trial to compare rivaroxaban plus aspirin versus acenocoumarol in patients with recurrent venous thromboembolism despite ongoing anticoagulation with rivaroxaban...

In patients who sustain a traumatic arterial injury to the lower extremities, timely intervention is key for limb salvage. Traditionally, patients with a popliteal injury have undergone an open surgical bypass but, in recent years, endovascular repair has become more frequent. We present the case of a 46-year-old male who sustained a right tibial/fibular fracture and an associated popliteal artery injury during a pedestrian versus car accident. At presentation, distal signals were not detectable on duplex ultrasonography, and computed tomography confirmed an occlusion of the P3 popliteal artery and proximal anterior tibial and tibioperoneal trunk, as well as a comminuted tibia and fibula fracture...

BACKGROUND: Patients with peripheral artery disease (PAD) requiring lower extremity revascularization (LER) have a high risk of adverse limb and cardiovascular events. The results from the VOYAGER PAD (efficacy and safety of rivaroxaban in reducing the risk of major thrombotic vascular events in subjects with symptomatic peripheral artery disease undergoing peripheral revascularization procedures of the lower extremities) trial have demonstrated that rivaroxaban significantly reduced this risk with an overall favorable net benefit for patients undergoing surgical revascularization...

OBJECTIVES: To determine whether there is a difference in orthopaedic trauma patient medication satisfaction and adherence using an oral versus subcutaneous injectable anticoagulant for venous thromboembolism chemoprophylaxis. DESIGN: Randomized controlled trial. SETTING: Single academic Level 1 trauma center. PARTICIPANTS: One hundred twenty adult orthopaedic trauma patients with operative pelvic or lower extremity fractures were randomized and completed the study...

BACKGROUND: The Clopidogrel and Acetylsalicylic Acid in Bypass Surgery for Peripheral Arterial Disease (CASPAR) trial is the only large, double-blind, placebo-controlled trial of dual antiplatelet therapy (DAPT) versus aspirin in patients with peripheral artery disease (PAD) after lower extremity revascularization (LER). The trial was neutral for index-graft occlusion/revascularization, amputation or death (hazard ratio [HR] 0.98, 95% confidence interval [CI] 0.78-1.23, p = .87) with an excess of global utilization of streptokinase and tissue plasminogen activator for occluded coronary arteries moderate or severe bleeding (HR 2...

BACKGROUND: COVID-19 disease is accompanied by a dysregulated immune response and hypercoagulability. The Anti-Coronavirus Therapies (ACT) inpatient trial aimed to evaluate anti-inflammatory therapy with colchicine and antithrombotic therapy with the combination of rivaroxaban and aspirin for prevention of disease progression in patients hospitalised with COVID-19. METHODS: The ACT inpatient, open-label, 2 × 2 factorial, randomised, controlled trial was done at 62 clinical centres in 11 countries...

Objective  Aspirin (acetylsalicylic acid, ASA) and rivaroxaban are anticoagulants that have increased in popularity due to ease of use in the prevention of venous thromboembolism (VTE) after total knee arthroplasty (TKA). The present study aimed to evaluate the efficacy of ASA compared with that of rivaroxaban on VTE prophylaxis in patients who underwent TKA. Method  Forty patients who had primary knee osteoarthritis and would undergo TKA were randomized into two groups. In total, 20 patients in the ASA group used oral aspirin, at a dose of 300 mg/day, for VTE prophylaxis after TKA, while 20 patients in the rivaroxaban group received oral rivaroxaban, at a dose of 10 mg/day...

BACKGROUND: Clinical trials provide conflicting evidence regarding oral factor Xa inhibitors for prevention of ischemic stroke in patients without a history of atrial fibrillation. METHODS: Critical appraisal of randomized clinical trials testing oral factor Xa inhibitors in patients without atrial fibrillation that reported ischemic stroke. RESULTS: Considering the 11 trials reporting >10 ischemic strokes during follow-up (97,578 participants, 1195 ischemic strokes), one tested apixaban (57 strokes), one betrixaban (52 strokes), and 9 rivaroxaban (1086 strokes)...

BACKGROUND: Knee arthroscopy (KA) is a routine orthopedic procedure recommended to repair cruciate ligaments and meniscus injuries and, in suitable cases, to assist the diagnosis of persistent knee pain. There is a small risk of thromboembolic events associated with KA. This systematic review aims to assess if pharmacological or non-pharmacological interventions may reduce this risk. This is an update of an earlier Cochrane Review. OBJECTIVES: To evaluate the efficacy and safety of interventions - whether mechanical, pharmacological, or a combination of both - for thromboprophylaxis in adults undergoing KA...

INTRODUCTION: Secondary prevention of cardiovascular events among patients with diagnosed cardiovascular disease and high ischemic risk poses a significant challenge in clinical practice. The combinations of aspirin with low-dose (LD) ticagrelor or LD rivaroxaban have shown superiority in preventing major adverse cardiovascular events (MACE) compared with aspirin treatment alone. The comparative value for money of these two regimens remains unexplored. METHODS: We analyzed each regimen's annual cost needed to treat (CNT) by multiplying the annualized number needed to treat (aNNT) by the annual cost of each drug...

Objective: This study aimed to investigate the cost-effectiveness of low-dose rivaroxaban plus aspirin versus aspirin alone for patients with stable cardiovascular diseases in the China. Methods: We used TreeAge 2019 to construct a Markov model to assess the direct healthcare costs and quality-adjusted life years for three therapies, namely low-does rivaroxaban plus aspirin, rivaroxaban alone, and aspirin alone. Transitional probabilities were derived from the COMPASS trial, and the costs and utilities were obtained from the Chinese Health Care Statistical Yearbook and published studies...
