Background: Studies have reported huge variations in the prescribing practice of warfarin. We carried out a clinical audit of warfarin use in an anticoagulation clinic of a tertiary care hospital. Methods: Patients receiving warfarin for at least 6 months were recruited and the following details were collected: demographics (age, body weight and gender); diagnoses; concomitant drugs. We calcula-ted CHA₂DS₂-VASc, HASBLED and SAMe-TT2R2 scores for each study participant...

BACKGROUND: Left atrial appendage occlusion is an increasingly proposed treatment for patients with atrial fibrillation and poor tolerance to anticoagulants. All endovascular devices require antithrombotic therapy. Anatomical and clinical variables predisposing to device-related thrombosis, as well as post-procedural peri-device leaks, could mandate the continuation or reintroduction of aggressive antithrombotic treatment. Because of the absence of foreign material inside the heart, epicardial appendage closure possibly does not necessitate antithrombotic therapy, but data of large series are missing...

BACKGROUND: Percutaneous left atrial appendage closure (LAAC) has been proposed as an alternative to anticoagulation therapy in patients with nonvalvular atrial fibrillation (NVAF) to decrease the thromboembolic risk, while avoiding the risks of chronic anticoagulation. This option may be attractive in patients with NVAF and chronic kidney disease (CKD), since they exhibit both high thromboembolic and bleeding risks. OBJECTIVE: To evaluate the prognostic impact of the presence of CKD in patients with atrial fibrillation undergoing LAAC peri-procedure and during the follow-up as compared with patients with preserved renal function...

INTRODUCTION: Atrial fibrillation (AF) is a prevalent disease considerably contributing to the worldwide cardiovascular burden. For patients at high thromboembolic risk (CHA2 DS2 -VASc ≥3) and not suitable for chronic oral anticoagulation, owing to history of major bleeding or other contraindications, left atrial appendage occlusion (LAAO) is indicated for stroke prevention, as it lowers patient's ischaemic burden without augmentation in their anticoagulation profile. METHODS AND ANALYSIS: Stand-Alone Left Atrial appendage occlusion for throMboembolism prevention in nonvalvular Atrial fibrillatioN DiseasE Registry (SALAMANDER) will be conducted in 10 heart surgery and cardiology centres across Poland to assess the outcomes of LAAO performed by fully thoracoscopic-epicardial, percutaneous-endocardial or hybrid endo-epicardial approach...

Objective: This study aimed to investigate the oral anticoagulant (OAC) usage among new-onset acute ischemic stroke (AIS) patients with nonvalvular atrial fibrillation (NVAF) in China, and to explore the possible influencing factors of influent anticoagulant therapy in these patients. Methods: The NVAF patients who experienced new-onset and non-fatal AIS from August 2011 to December 2018 in the China Atrial Fibrillation Registry (China-AF), were enrolled. The follow-up ended in December 2019. Information including patients' demographic characteristics, medical history, medication usage, which were collected before and after the index stroke, were analyzed...

INTRODUCTION: Patients with atrial fibrillation (AF) are frequently admitted from the emergency department (ED), and when discharged, are not reliably prescribed indicated anticoagulation. We report the impact of a novel computerized ED AF pathway orderset on discharge rate and risk-appropriate anticoagulation in patients with primary AF. METHODS: The orderset included options for rate and rhythm control of primary AF, structured risk assessment for thrombotic complications, recommendations for anticoagulation as appropriate, and follow up with an electrophysiologist...

Background. Patients with nonvalvular atrial fibrillation (NVAF) have five times higher risk of stroke than the general population. Anticoagulation (ACO) in NVAF is a class I indication after assessing the CHA2DS2-VASc and HAS-BLED scores. However, in the real world, NVAF patients receive less ACO than needed due to patients' comorbidities that can be assessed by the Charlson comorbidity index (CCI). The use of non-antivitamin K anticoagulants (NOAC) has improved the decision to anticoagulate. Objective . We analyzed the factors influencing the ACO prescribing decision in NVAF patients in the real world and the changes induced by the introduction of NOAC...

OBJECTIVE: People with serious mental illnesses (SMI) have an increased risk of stroke compared to the general population. This study aims to evaluate oral anticoagulation prescription trends in atrial fibrillation (AF) patients with and without a comorbid SMI. METHODS: An open-source retrieval system for clinical data (CogStack) was used to identify a cohort of AF patients with SMI who ever had an inpatient admission to King's College Hospital from 2011 to 2020...

It has been shown that endocardial occlusion of the left atrial appendage (LAA) is equally effective in preventing embolic events compared to oral anticoagulation in patients with nonvalvular atrial fibrillation. An 82-year-old female patient was admitted for LAA occlusion for repetitive GI bleeding. She had high CHADSVASC Score and HASBLED with long persistent atrial fibrillation with many comorbities. The preprocedural transesophageal echo revealed a great mass in the left atrium (Picture 1). Cardiac surgery was denied, we performed an epicardial only ligation for closing the LAA...

AIMS: To identify the extent and associated factors for patients with prolonged prothrombin time, international normalized ratio (PT-INR) and the dosage modifications carried out with warfarin. BACKGROUND: Studies evaluating patients on warfarin with supratherapeutic anticoagulation are limited. It is vital to understand the management strategies for patients receiving warfarin who are bleeding and those with only supratherapeutic PT-INR. OBJECTIVE: To evaluate the factors associated with supratherapeutic anticoagulation without bleeding with warfarin...

BACKGROUND AND PURPOSE: Left atrial appendage occlusion (LAAO) is an accepted therapeutic option for stroke prevention; however, the ideal technique and device have not yet been identified. In this study we evaluate the potential role of a heart team approach for patients contraindicated for oral anticoagulants and indicated for left atrial appendage closure, to minimize risk and optimize benefit in a patient-centered decision-making process. METHODS: Forty patients were evaluated by the heart team for appendage occlusion...

BACKGROUND: There is lack of large data from South-Asian region on atrial fibrillation and it is imperative that clinical presentation, prognostic factors, management pursued, and outcomes are known for this part of the world. Once collective evidence for the region is known, region-specific guidelines can be laid forward. OBJECTIVES: To evaluate clinical characteristics and prognostic factors of atrial fibrillation at a tertiary care center of Pakistan. METHODS: This was a retrospective study conducted at a tertiary care center of Pakistan...

BACKGROUND: The adherence of oral anticoagulant (OAC) therapy among nonvalvular atrial fibrillation (NVAF) patients with acute ischemic stroke (AIS) in China during recent years was unclear, and the possible factors that influenced the initiation and persistent use of OAC were needed to be explored. METHODS: A total of 1085 NVAF patients, who experienced new-onset and nonfatal AIS from August 2011 to December 2020 during follow-ups in the China Atrial Fibrillation Registry (China-AF), were enrolled...

BACKGROUND: The PRAGUE-17 (Left Atrial Appendage Closure vs Novel Anticoagulation Agents in Atrial Fibrillation) trial demonstrated that left atrial appendage closure (LAAC) was noninferior to nonwarfarin direct oral anticoagulants (DOACs) for preventing major neurological, cardiovascular, or bleeding events in patients with atrial fibrillation (AF) who were at high risk. OBJECTIVES: This study sought to assess the prespecified long-term (4-year) outcomes in PRAGUE-17...

BACKGROUND: Atrial fibrillation (AF) is common in older adults. CHA2DS2-VASC (congestive heart failure, hypertension, age ≥75 (doubled), diabetes mellitus, prior stroke or transient ischemic attack (doubled), vascular disease, age 65-74, female) and HASBLED(Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile INR, Elderly, Drugs/Alcohol Concomitantly) are the most established risk stratification tools in assessing suitability for anticoagulation in AF...

Background: Data reporting a head-to-head comparison between Amulet and Watchman devices are scarce. The aim of this study was to compare the Watchman™ versus Amulet™ left atrial appendage closure (LAAC) devices in a consecutive, industry-independent registry. Methods: Patients who underwent LAAC using Watchman or Amulet devices from January 2014 to December 2019 at the University Heart Center Lübeck, Lübeck, Germany were included in the present analysis. Primary endpoints included periprocedural complications (in-hospital death, pericardial tamponade, device embolization, stroke, major bleeding and vascular access complications), and complications during long-term follow-up (ischemic stroke, hemorrhagic stroke, thromboembolism, device thrombus, bleeding and death)...

BACKGROUND: Percutaneous left atrial appendage closure (LAAC) has been proposed as an alternative to anticoagulation therapy in patients with nonvalvular atrial fibrillation to decrease the thromboembolic risk, while avoiding the risks of chronic anticoagulation. This option may be attractive in patients with nonvalvular atrial fibrillation and chronic kidney disease (CKD), since they exhibit both high-thromboembolic and bleeding risks. OBJECTIVE: To evaluate the prognostic impact of the presence of CKD in patients with atrial fibrillation undergoing LAAC peri-procedure and during the follow-up as compared with patients with preserved renal function...

Stroke is a common cause of mortality and serious long-term disability worldwide. In the acute setting, current American Heart Association/American Stroke Association guidelines do not recommend routine anticoagulation for the management of acute ischemic strokes. However, short-term use of unfractionated heparin (UFH) in select subpopulations has demonstrated improved outcomes. While tools such as CHADSVASC and HASBLED scores are useful in stratifying risk of long-term anticoagulation in patients with nonvalvular atrial fibrillation and additional risk factors, the carefully selected patient populations for the design of these studies do not account for risk of hemorrhage from other preexisting conditions...

BACKGROUND: Patients with nonvalvular atrial fibrillation (NVAF) and type 2 diabetes are at risk of kidney, limb, and ophthalmic complications. We evaluated the rate of these complications and death in patients with NVAF and type 2 diabetes prescribed rivaroxaban or warfarin. METHODS: We analyzed Optum de-Identified electronic health record (EHR) data from 11/2010-12/2019. We included adults with NVAF and T2D newly initiated on rivaroxaban or warfarin with ≥12 months of prior EHR activity...

BACKGROUND: Left atrial appendage occlusion (LAAO) has been widely adopted as a strategy for stroke prevention in patients with atrial fibrillation ineligible for oral anticoagulation. OBJECTIVE: The purpose of this study was to explore longer-term "real-world" safety and efficacy outcomes in patients undergoing LAAO given varied practices in antithrombotic regimens and adoption of same-day discharge. METHODS: Analysis of acute procedural and long-term outcome data was performed for all patients undergoing LAAO implant in a United Kingdom tertiary center over an 11-year period...
