Paroxysmal atrial fibrillation oral anticoagulant

Management of atrial fibrillation (AF) is a clinical conundrum in people with kidney failure. Stroke risk is disproportionately high, but clinicians have a limited armamentarium to improve outcomes in this population in whom there is a concurrently high bleeding risk. Direct oral anticoagulants may have a superior benefit-risk profile compared with vitamin K antagonists in people on hemodialysis. Although research has predominantly focused on identifying a safe and effective oral anticoagulation option to reduce stroke risk in people with kidney failure (and predominantly those on hemodialysis), it remains uncertain how clinicians discriminate between people who would derive net clinical benefit as opposed to net harm...

BACKGROUND Hemorrhagic cholecystitis is a rare cause of abdominal pain, which can result from malignancy, bleeding, or trauma. The presentation, which includes right upper-quadrant pain, nausea, and vomiting, can overlap with other disease states, thereby rendering the diagnosis challenging. CASE REPORT We describe a patient taking apixaban wo had paroxysmal atrial fibrillation with history of joint pain on long-term steroids who developed hemorrhagic cholecystitis following an episode of pneumonia secondary to SARS-CoV-2 virus (COVID-19) infection...

BACKGROUND: This ANAFIE Registry sub-analysis investigated 2-year outcomes and oral anticoagulant (OAC) use stratified by glycated hemoglobin (HbA1c) levels among Japanese patients aged ≥ 75 years with non-valvular atrial fibrillation (NVAF) with and without clinical diagnosis of diabetes mellitus (DM). METHODS: The ANAFIE Registry was a large-scale multicenter, observational study conducted in Japan; this sub-analysis included patients with baseline HbA1c data at baseline...

Atrial fibrillation (AF) is associated with an increased risk of stroke. Therefore, patients with AF require appropriate management and anticoagulant therapy. To balance therapy risks and benefits, oral anticoagulants (OAC) treatment should be 'tailored' in patients at a high risk of stroke and bleeding. However, some studies have demonstrated that certain groups of patients do not receive anticoagulants despite the high risk of stroke or thromboembolism. The study aimed to analyse therapeutic methods of stroke prevention in very high-risk patients (CHA2 DS2 -VASc score of ≥5 in men and ≥6 in women), identify factors predisposing against the use of OACs and assess the administration of anticoagulants before the introduction of non-vitamin K antagonist OAC (NOAC) in 2004-2011 and beyond (years 2012-2019)...

For the diagnosis of atrial fibrillation, it is mandatory to make an ECG during the arrhythmia. In patients with paroxysmal atrial fibrillation this can be challenging. Consumer wearables such as smart watches with automated AF detection can be helpful for diagnosing even asymptomatic AF, as long as they offer the possibility to record a one lead ECG rhythm strip. Once AF is diagnosed, therapeutic decisions, such as rate-control versus rhythm-control and start of oral anticoagulation therapy need to be made on an individual basis in each patient...

Direct oral anticoagulants (DOACs) are well known to be associated with bleeding complications. However, little is known about their association with atraumatic splenic rupture, a potentially fatal condition. We present the case of a 73-year-old female with paroxysmal atrial fibrillation managed with rivaroxaban who developed a spontaneous atraumatic splenic rupture. This highlights the importance of recognizing this complication in patients without previous risk factors, such as abdominal trauma or infiltrative splenic disease, who are under anticoagulation with DOACs...

BACKGROUND: Current recommendations regarding the use of surgical left atrial appendage (LAA) closure to prevent thromboembolisms lack high-level evidence. Patients undergoing open-heart surgery often have several cardiovascular risk factors and a high occurrence of postoperative atrial fibrillation (AF)-with a high recurrence rate-and are thus at a high risk of stroke. Therefore, we hypothesized that concomitant LAA closure during open-heart surgery will reduce mid-term risk of stroke independently of preoperative AF status and CHA2 DS2 -VASc score...

BACKGROUND: Device-related thrombus (DRT) after left atrial appendage closure (LAAC) is associated with adverse outcomes, i.e. ischemic stroke or systemic embolism (SE). Data on predictors of stroke/SE in the context of DRT are limited. AIMS: This study aimed to identify predisposing factors for stroke/SE in DRT patients. In addition, the temporal connection of stroke/SE to DRT diagnosis was analyzed. METHODS: The EUROC-DRT registry included 176 patients, in whom DRT after LAAC were diagnosed...

BACKGROUND: Antiarrhythmic drugs and transcatheter ablation in atrial fibrillation (AF) provide suboptimal rhythm control with a not negligible rate of failure in paroxysmal AF (PAF) and nonparoxysmal AF (n-PAF) at midterm and long-term follow-up. This study evaluated the safety profile and long-term efficacy of thoracoscopic ablation in patients with lone AF. METHODS: A consecutive 153 patients with lone AF were prospectively enrolled and underwent thoracoscopic surgical ablation...

BACKGROUND: The present study aimed to investigate the prevalence, predictors, and management of left atrial appendage (LAA) thrombogenic milieu (TM) identified with transesophageal echocardiography (TEE) in non-valvular atrial fibrillation (NVAF) patients with low to moderate thromboembolic (TE) risk. METHODS: We retrospectively analyzed the baseline clinical data and TEE findings in 391 NVAF patients (54.7 ± 8.9 years, 69.1% male) with low to moderate TE risk according to the CHA2 DS2 -VASc score...

Atrial fibrillation (AF) is the most common complication of cardiac surgery, occurring in up to half of patients. Post-operative AF (POAF) refers to new-onset AF in a patient without a history of AF that occurs within the first 4 weeks after cardiac surgery. POAF is associated with short-term mortality and morbidity, but its long-term significance is unclear. This article reviews existing evidence and research challenges for the management of POAF in patients who have had cardiac surgery. Specific challenges are discussed in four phases of care...

BACKGROUND: Thermal left atrial ablation can cause bronchial damage. Pulsed field ablation (PFA) is a novel, nonthermal ablation modality for paroxysmal atrial fibrillation. We report on bronchial effects after pulmonary vein isolation using PFA for paroxysmal atrial fibrillation. METHODS: A computed tomography scan showing the respiratory tract adjacent to the left atrial was obtained. Oral anticoagulation was interrupted on procedure day. Peri-procedurally, patients received heparin with an activated clotting time goal of >350 seconds...

BACKGROUND: Although anticoagulants are indicated for many elderly patients with non-valvular atrial fibrillation (NVAF), some patients do not receive anticoagulant therapy, whose characteristics and outcomes are diverse. METHODS AND RESULTS: In this sub-analysis of the All Nippon AF In the Elderly (ANAFIE) Registry, the phenotypes of patients who were not receiving anticoagulants at baseline were evaluated by cluster analysis using Ward's linkage hierarchical algorithm...

BACKGROUND: Although peri-device leakage is frequently observed after left atrial appendage occlusion (LAAO), there is no consensus on the optimal management strategy. It is unknown whether additional plugging should be preferred over surgical exclusion of the LAA, as experience with additional plugging is limited. CASE SUMMARY: In this case report, we demonstrate the clinical implications of additional plugging and surgical exclusion in a 65-year-old male patient with peri-device leakage and recurrent thromboembolic events...

UNLABELLED: ObjectivesThis study aims to investigate US active duty (AD) military members diagnosed with atrial fibrillation (AF) and the temporal trends of systemic anticoagulation (AC). Our secondary objective is to study the AC prescriptions in AD military members diagnosed with AF and associated military dispositions and deployment rates. DESIGN AND SETTING: A retrospective investigation of Tricare pharmacy AC prescriptions within the San Antonio Military Health System from January 2004 to July 2019 for AD individuals diagnosed with AF was performed...

BACKGROUND: Elderly patients with atrial fibrillation (AF) are at a higher risk for all-cause mortality and heart failure. Rate control is an essential component in AF management. This exploratory study assessed the relationship between resting heart rate during AF at baseline and clinical outcomes in Japanese elderly non-valvular AF (NVAF) patients, using the All Nippon AF In the Elderly Registry (ANAFIE) dataset. METHODS: This sub-cohort included patients who agreed to participate and presented AF at the enrollment of the ANAFIE study...

BACKGROUND: The effects of statins in patients with non-valvular atrial fibrillation (NVAF) taking oral anticoagulants (OACs) are not well-studied. This study was a historical multicenter registry of patients with NVAF taking OACs in Japan. METHODS: We excluded those patients with mechanical heart valves or a history of pulmonary or deep vein thrombosis. Overall, 7826 patients were registered on 26 February 2013 and followed until 25 February 2017. We compared those with versus without statin treatment (statin vs...

Background  Compared with usual care, guideline-adherent stroke prevention strategy, based on the ABC (Atrial fibrillation Better Care) pathway, is associated with better outcomes. Given that stroke prevention is central to atrial fibrillation (AF) management, improved efforts to determining predictors of adherence with 'A' (avoid stroke) component of the ABC pathway are needed. Purpose  We tested the hypothesis that more sophisticated methodology using machine learning (ML) algorithms could do this. Methods  In this post-hoc analysis of the BALKAN-AF dataset, ML algorithms and logistic regression were tested...

Atrial fibrillation (AF) is a major cause of recurrent stroke and transient ischaemic attack (TIA) in the UK. As many patients can have asymptomatic paroxysmal AF, prolonged arrhythmia monitoring is advised in selected patients following a stroke or TIA. This service evaluation assessed the clinical and potential health economic impact of prolonged arrhythmia monitoring post-stroke using R-TEST monitoring devices. This was a prospective, case-controlled, service evaluation in a single health board in the North of Scotland...

BACKGROUND: A hemothorax as the initial manifestation of bronchiectasis is extremely rare. We report a case of a sudden hemothorax due to exacerbation of clinically latent bronchiectasis under a direct oral anticoagulant. CASE PRESENTATION: A 77-year-old woman presented with chest pain and a fever noted since the day before. She had stage G3 chronic kidney disease and received edoxaban for paroxysmal atrial fibrillation. She had no history of trauma or respiratory symptoms...
