INTRODUCTION: Electronic health records (EHR) contain data valuable for clinical research but in textual format, requiring encoding to databases by a human- a lengthy and costly process. Natural language processing (NLP) is a computational technique that allows text analysis. OBJECTIVES: To demonstrate a practical use case of NLP for a large retrospective study cohort characterization and compare it to a human retrieval. PATIENTS AND METHODS: Anonymized discharge documentation of 10314 patients from the cardiology tertiary care department was analyzed for inclusion in the CRAFT registry (NCT02987062) of patients with atrial fibrillation (AF)...

BACKGROUND: Traditional scores as CHADS2 and CHA2DS2-Vasc are suitable for predicting stroke and systemic embolism in patients with atrial fibrillation (AF) and have shown to be also associated with mortality. Other more complex scores have been recommended for survival prediction. The purpose of our analysis was to test the performance of different clinical scores in predicting 1-year mortality in AF patients. MATERIAL AND METHODS: CHADS2 and CHA2DS2-Vasc scores were calculated for AF patients of the BLITZ-AF register and compared to R2-CHADS2, R2-CHA2DS2-Vasc and CHA2DS2VASc-RAF scores in predicting 1-year survival...

Stroke incidence is the most severe complication associated with atrial fibrillation (AF), and the most common site of thrombus formation in AF patients is the left atrial appendage (LAA). This study was developed to use two-dimensional speckle tracking imaging (2D-STI) to explore associations between LAA strain/strain rate and stroke incidence and to evaluate the value of utilizing LAA strain and strain rate values to support the stratification of nonvalvular AF (NVAF) patients based on stroke risk. A total of 486 AF patients who had undergone transesophageal echocardiography to exclude potential intracardiac thrombosis between March 2021 and November 2022 were consecutively enrolled...

BACKGROUND AND PURPOSE: <p>Atrial fibrillation diagnosed after stroke (AFDAS) is a new term used for AF resulting from autonomic dysregulation. It is associated with a lower stroke recurrence compared to patients with known AF before a stroke (KAF). The aim of the study was to explore the characteristics and mortality rates in AFDAS patients.</p>. METHODS: <p>134 ischemic stroke patients (66.1&plusmn;14.2 years old, n=73 male) were consecutively included in the study...

Background and Objectives : Percutaneous left-atrial appendage (LAA) occlusion is an important therapeutic option for preventing cardioembolic stroke in patients with non-valvular atrial fibrillation (AF) at high risk of thromboembolic events and with contraindications for oral anticoagulation (OAC). It is usually performed with transesophageal echocardiography (TOE) guidance under general anesthesia (GA). In this retrospective study, we present a multicenter experience of LAA occlusion performed with conscious sedation (CS) without an anesthesiologist on site...

BACKGROUND AND AIMS: Since the introduction of direct oral anticoagulant (DOAC) for atrial fibrillation (AF) therapy, inappropriate and/or underdosing of these drugs has been a major clinical challenge. We evaluated the characteristics of AF patients treated with inappropriate and low dose DOACs. METHODS: AF patients treated with inappropriate and low dose DOACs from October 2021 to December 2021 were evaluated from the Prospective French National Registry (PAF)...

BACKGROUND: While studies have shown the advantages of computed tomography angiography (CTA) over transesophageal echocardiography (TEE) in left atrial appendage closure (LAAC) preprocedural planning for WATCHMAN™ legacy and FLX devices, there has been no reported long-term data for this approach. OBJECTIVES: We sought to evaluate long-term outcomes using CTA-based preprocedural planning for LAAC using the WATCHMAN™ device. METHODS: A prospective analysis of 231 consecutive patients who underwent LAAC in a single, large academic hospital in the United States was conducted over a 5-year period...

DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: To measure the effect of clinical decision support (CDS) on anticoagulation rates in patients with atrial fibrillation (AFib) or atrial flutter (AFlut) at high stroke risk and receiving care in outpatient settings, and to assess provider response to CDS...

BACKGROUND: Catheter ablation (CA) combined with left atrial appendage occlusion (LAAO) is a feasible approach for atrial fibrillation (AF) patients. Its role in octogenarians with AF is unclear. HYPOTHESIS: In AF patients over 80 years, CA combined with LAAO is a feasible way in restoring sinus rhythm and preventing stroke. METHODS: This is a single-center retrospective study. Patients who underwent CA and LAAO in a single procedure between March 2018 and December 2020 were included...

Atrial fibrillation (AF) patients are more susceptible to dementia, but the results about the effect of oral anticoagulants (OACs) on the risk of dementia are not consistent. We hypothesize that OAC is associated with a reduced risk of dementia with AF and that nonvitamin K antagonist oral anticoagulants (NOAC) are superior to vitamin K antagonists (VKA). Four databases were systematically searched until July 1, 2022. Two reviewers independently selected literature, evaluated quality, and extracted data. Data were examined using pooled hazard ratios (HRs) and 95% confidence intervals (CIs)...

BACKGROUND: ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI) are at increased risk for contrast-induced nephropathy (CIN) than elective PCI procedures. Routine calculation of Mehran's score is limited by its complexity and difficulty to memorize. This study evaluated CHA2 DS2 -VASc score predictive utility for CIN in STEMI patients before pPCI. RESULTS: Consecutive 500 acute STEMI patients presenting to two Egyptian pPCI centers were recruited...

Closure of the left atrial appendage (LAAO) represents a valid option for the prevention of cardio-embolic stroke in patients with atrial fibrillation (AF) at high bleeding risk. Previous studies had shown that the atrial appendage represents the site of atrial thrombus formation in about 90% of cases in the presence of non-valvular AF. In all patients with AF and higher thromboembolic risk (in particular with CHA2DS2VASc score ≥2 in women and ≥1 in men) there is an indication for thromboembolic prophylaxis with AOC (oral anti-coagulants)...

OBJECTIVE: This study aimed to compare the sympathetic nervous system activity of atrial ���brillation patients without structural heart disease and the normal population in terms of urinary metanephrine levels. METHODS: Our study was conducted with 40 paroxysmal or persistent patients without structural heart disease and CHA2DS2VASc score of 0 or 1 and 40 healthy controls. Laboratory parameters, demographic characteristics, and 24-hour urine metanephrine levels were compared between the 2 groups included in the study...

OBJECTIVES: Since recent data demonstrated the benefit of left atrial appendage (LAA) amputation in patients with atrial fibrillation, the long-term impact of LAA amputation on stroke rate and mortality in patients with no history of atrial fibrillation is still unknown. METHODS: Patients with no history of atrial fibrillation who underwent coronary artery bypass grafting by off-pump technique between 2014 and 2016 were retrospectively examined. Cohorts were divided by the concomitant execution of LAA amputation and propensity score matching was applied by baseline characteristics...
