A prospective evaluation of edoxaban compared to warfarin in subjects undergoing cardioversion of atrial fibrillation: The EdoxabaN vs. warfarin in subjectS UndeRgoing cardiovErsion of Atrial Fibrillation (ENSURE-AF STUDY)

Lip , Jose Merino , Michael Ezekowitz , Kenneth Ellenbogen , Dmitry Zamoryakhin , Hans Lanz , James Jin , Naab Al-Saadi , Michele Mercuri , Andreas Goette We designed a prospective, randomized, open-label, blinded endpoint evaluation(PROBE) parallel group Phase 3b clinical trial comparing edoxaban (a new oral factor Xa inhibitor) with enoxaparin/warfarin followed by warfarin alone in subjects undergoing planned electrical cardioversion of non-valvular AF. The primary efficacy endpoint is the composite endpoints of st...

Reversing the Effect of Oral Anticoagulant Drugs: Established and Newer Options
Abstract The vitamin K antagonists (VKAs) have been the standard (and only) oral anticoagulants used for the long-term treatment or prevention of venous thromboembolism or stroke in patients with atrial fibrillation. The coagulopathy induced by VKAs can be reversed with vitamin K, and in urgent situations, the vitamin K-dependent coagulation factors can be replaced by transfusion. In the last decade, a new class of oral anticoagulants has been developed, direct oral anticoagulants that bind to a specific coagulation factor and neutralize it. These compounds were shown to be effective and safe compared with the VKA...

Anticoagulation Control in Warfarin Treated Patients Undergoing Cardioversion for Atrial Fibrillation (From the ENSURE-AF Trial)
In the ENSURE-AF study (NCT 02072434), edoxaban was compared to enoxaparin –warfarin in 2199 patients undergoing electrical cardioversion of non-valvular atrial fibrillation (AF). In this multicenter PROBE trial, we analyzed patients randomized to enoxaparin–warfarin. We determined time to achieve therapeutic range (TtTR), time in therapeutic range (TiTR), their clinic al determinants, relation to SAMe-TT2R2 score, and impact on primary endpoints (composite of stroke, systemic embolic event [SEE], myocardial infarction [MI], and cardiovascular death [CVD] and composite of major + clinically relevant non-major [CRNM] bleeding).

Anticoagulation Control in Warfarin-Treated Patients Undergoing Cardioversion of Atrial Fibrillation (from the Edoxaban Versus Enoxaparin –Warfarin in Patients Undergoing Cardioversion of Atrial Fibrillation Trial)
In the Edoxaban Versus Enoxaparin –Warfarin in Patients Undergoing Cardioversion of Atrial Fibrillation (ENSURE-AF) study (NCT 02072434), edoxaban was compared with enoxaparin–warfarin in 2,199 patients undergoing electrical cardioversion of nonvalvular atrial fibrillation (AF). In this multicenter prospective randomized open bl inded end-point trial, we analyzed patients randomized to enoxaparin–warfarin. We determined time to achieve therapeutic range (TtTR); time in therapeutic range (TiTR); their clinical determinants; relation to sex, age, medical history, treatment, tobacco use, race risk (SAMe-TT2R2) score; an...

Pulmonary embolism four days after interruption of therapy with rivaroxaban.
We report on a 58-year-old male with paroxysmal atrial fibrillation (AF) with a CHA2DS2VASC score of 4 who developed central pulmonary embolism four days after interruption of rivaroxaban because of parotid surgery. He had received 40 mg enoxaparin/d. The parotid gland was partially resected within 6 hours without blood loss. Pulmonary embolism and AF occurred on the first postoperative day. He recovered with low-molecular-weight heparin in therapeutic dosages and amiodarone and was discharged with phenprocoumon. The relevance of a rivaroxaban rebound phenomenon, manifesting as arterial embolism, stroke or venous thrombo...

Health Care Cost In Patients Undergoing Electrical Cardioversion: An Analysis From The Edoxaban Versus Warfarin In Subjects Undergoing Cardioversion of Atrial Fibrillation (ENSURE-AF) Study
Electrical cardioversion (EC) restores and maintains sinus rhythm in atrial fibrillation (AF) patients. Edoxaban, a direct oral anticoagulant indicated for prevention of stroke or systemic embolic event (SEE) in patients with non-valvular atrial fibrillation (NVAF) was compared with enoxaparin –warfarin in patients undergoing EC in ENSURE-AF (NCT 02072434) study, a phase 3b open-label, multi-national open-label trial comparing edoxaban with enoxaparin/warfarin followed by warfarin alone in 2,199 NVAF patients.

Impact of Body Mass Index on Outcomes in the Edoxaban Versus Warfarin Therapy Groups in Patients Undergoing Cardioversion of Atrial Fibrillation (From ENSURE-AF)
In the EdoxabaN versus warfarin in subjectS UndeRgoing cardiovErsion of Atrial Fibrillation (ENSURE-AF) study (NCT 02072434), edoxaban showed similar efficacy and safety vs enoxaparin –warfarin in patients undergoing electrical cardioversion of nonvalvular atrial fibrillation. In this ancillary analysis, we compared the primary efficacy (composite of stroke, systemic embolic event, myocardial infarction, and cardiovascular [CV] death, overall study period) and safety (composite of major and clinically relevant nonmajor [CRNM] bleeding, on-treatment) endpoints in relation to body mass index (BMI;

Spontaneous Retroperitoneal Hemorrhage
A 68-year-old man was admitted for pneumonia. Three months earlier he had suffered an embolic ischemic stroke related to newly diagnosed atrial fibrillation. He had residual aphasia, right hemiparesis with hemianesthesia, and was treated with subcutaneous enoxaparin 60  mg twice daily at the time of admission. Initial laboratory tests showed a white blood cell count of 12.480/mm3 and a hemoglobin level of 12.6 g/dL.

Resumo Baixas doses de edoxabana e enoxaparina s ódica foram objeto de uma comparação retrospectiva implementada com a técnica do escore de propensão a fim de mitigar os efeitos das diferenças nas características clínicas basais de duas coortes e minimizar o risco de viés. Posteriormente, usando um modelo de riscos proporcionais de Cox, a valiou-se a associação de cada tipo de terapia com o risco do composto de morte por todas as causas, acidente vascular cerebral/ataque isquêmico transitório, hospitalizações e ocorrência de sangramentos maiores. Para essa análise, um valor de p< 0,05 foi considerado es...
