BACKGROUND: Atrial fibrillation (AFib) is the most common form of heart arrhythmia and a potent risk factor for stroke. Nonvitamin K antagonist oral anticoagulants (NOACs) are routinely prescribed to manage AFib stroke risk; however, nonadherence to treatment is a concern. Additional tools that support self-care and medication adherence may benefit patients with AFib. OBJECTIVE: The aim of this study was to evaluate the perceived usability and usefulness of a mobile app designed to support self-care and treatment adherence for AFib patients who are prescribed NOACs...

The European Society of Cardiology (ESC) guidelines for management of atrial fibrillation (AF) recommend the use of CHA2DS2VASc risk score for assessment of thromboembolic (TE) risk, whereas the stratification of bleeding risk should be obtained by HAS-Bleed to balance the most appropriate anticoagulation (OAC) therapy. However, men with CHA2DS2VASc score = 1 and women with CHA2DS2VASc = 2, who are at intermediate TE risk, represent a grey zone where guidelines do not provide a definite OAC indication...

OBJECTIVES: Atrial fibrillation (AFib) is the most common dysrhythmia in the United States. Patients seen in the emergency department (ED) in rapid AFib are often started on intravenous rate-controlling agents and admitted for several days. Although underlying and triggering illnesses must be addressed, AFib, intrinsically, is rarely life-threatening and can often be safely managed in an outpatient setting. At our academic community hospital, we implemented an algorithm to decrease hospital admissions for individuals presenting with a primary diagnosis of AFib...

BACKGROUND: The first line drugs for treatment of non-valvular atrial fibrillation (AF) are non-vitamin K oral anticoagulants (NOACs), which are preferred over vitamin K antagonists (VKAs). There is some evidence that an everyday clinical practice is distant from the guidelines. AIM: The study aimed to compare characteristics of patients on VKAs, dabigatran and rivaroxaban met in everyday practice (i.e. baseline characteristics, drugs' doses, risk factors of bleeding and thromboembolic events)...

BACKGROUND: Concealed left-sided accessory pathways (CLAP) are a cause of supraventricular tachycardia (SVT) in the young. Most are mapped with right ventricular (RV) apical/outflow pacing. Rarely, alternative means of mapping are required. We review our experience from three pediatric electrophysiology (EP) centers with a rare form of "hidden" CLAP. METHODS: All patients <21 years undergoing EP study from 2008 to 2014 with a "hidden" CLAP (defined as an accessory pathway [AP] for which RV pacing at cycle lengths [CL] stable for mapping did not demonstrate eccentric retrograde conduction) were included...

As an innovative approach to improve quality of surgical care, we combined surgeon self-assessment and anonymized peer comparison with continuous quality improvement seminars using positive deviance (CQI/PD) to identify surgeon(s) with the lowest rates of adverse events (AEs) to guide group practice recommendations. Our objective was to quantify the impact these interventions on postoperative AEs rates after major non-cardiac chest operations. All postoperative AEs after all thoracic operations (n = 1,084, March, 2013 to February, 2016, single-center) were prospectively collected using the thoracic morbidity and mortality system, based on Clavien-Dindo schema...

Dobutamine is commonly used worldwide and included in the protocol for early goal-directed therapy (EGDT). Since the use of dobutamine in EGDT was reported, it has been considered to be an important component, especially in the treatment of septic patients with myocardial dysfunction. However, it is questionable whether dobutamine improves the mortality of sepsis and septic shock. In three recent randomized controlled trials (ProCESS, ProMISe, and ARISE trials), the frequency of dobutamine use was significantly higher in the EGDT group than in the standard care group, but there were no significant differences in the mortality between the groups...

OBJECTIVES: Recurrent arrhythmia after pulmonary vein isolation (PVI) by radiofrequency (RF) ablation in patients with atrial fibrillation (AFIB) remains a significant challenge. Using contact force (CF) sensing ablation catheters, we aimed to identify procedure related parameters associated with recurrence after de-novo PVI in patients with AFIB. METHODS: Consecutive patients undergoing a de-novo PVI procedure (n = 120, 63% paroxysmal and 37% persistent AFIB) employing a force-sensing ablation catheter were included...

Ebstein's anomaly (EA) is a rare congenital heart disease characterized by "atrialization" of the right ventricle, due to apical displacement of the tricuspid leaflets into the right ventricle. Patients with EA may develop all kinds of supraventricular arrhythmias requiring radiofrequency ablation. Atrial fibrillation (Afib) is a common arrhythmia in EA patients, and results in debilitating symptoms that often require surgical treatment. This is a follow-up report of 2 patients with EA undergoing radiofrequency ablation for Afib...

BACKGROUND/AIMS: TASK channels belong to the two-pore-domain potassium (K2P) channel family. TASK-1 is discussed to contribute to chronic atrial fibrillation (AFib) and has been together with uncoupling protein 1 found as a marker protein of brown adipose tissue (BAT) fat. In addition, TASK-1 was linked in a genome-wide association study to an increased body mass index. A recent study showed that TASK-1 inhibition is causing obesity in mice by a BAT whitening and that these effects are linked to the mineralocorticoid receptor pathway, albeit the mechanism remained elusive...

In this study, we investigated the correlation of air temperature, pressure and concentration of air pollutants with the rate of admissions for cardiac arrhythmias at two clinical centers in the area with a humid continental climate. This retrospective study included 3749 patients with arrhythmias admitted to emergency department (ED). They were classified into four groups: supraventricular tachycardia (SVT), ventricular tachycardia (VT), atrial fibrillation/undulation (Afib/Aund), and palpitations (with no ECG changes, or with sinus tachycardia and extrasystoles)...

The effectiveness and safety of a pharmacologic intervention is highly dependent on patient's capability to follow the recommended treatment regimen. Non-adherence to pharmacologic treatments is associated with worsening conditions including hospitalization and death. This is a significant burden to healthcare systems on a global scale with non-adherence rates being as high (or higher) as 50% in the first treatment year. The most common causes for non-adherence are forgetfulness, busy lifestyle or complexity and changes in therapeutic schedules...

Arrhythmias have been one of the common complications in epilepsy patients and have also been the reason for death. However, limited data exist about the burden and outcomes of arrhythmias by subtypes in epilepsy. Our study aims at evaluating the burden and differences in outcomes of various subtypes of arrhythmias in epilepsy patient population. The Nationwide Inpatient Sample (NIS) database from 2014 was examined for epilepsy and arrhythmias related discharges using appropriate International Classification of Disease, Ninth Revision Clinical Modification (ICD-9-CM) codes...

BACKGROUND: Sleep-disordered breathing (SDB) represents a common and highly relevant co-morbidity in patients with atrial fibrillation (Afib). Obstructive sleep apnea (OSA) has been identified as an independent risk factor for developing Afib and for Afib recurrence after treatment, but the role of central sleep apnea (CSA) is less clear. This study investigated characteristics of SDB in Afib patients with preserved left ventricular ejection fraction (PEF). METHODS AND RESULTS: Consecutive patients (07/2007 to 03/2016) with documented Afib at hospital admission and PEF undergoing 6-channel cardiorespiratory polygraphy (PG) screening were retrospectively analyzed...

OBJECTIVE/BACKGROUND: Sleep-disordered breathing (SDB) is common in patients with atrial fibrillation (Afib). Although a high proportion of respiratory events are hypopneas, previous studies have only used apneas to differentiate obstructive (OSA) from central (CSA) sleep apnea. This study investigated the impact of using apneas and hypopneas versus apneas only to define the predominant type of SDB in Afib patients with preserved ejection fraction. PATIENTS/METHODS: This retrospective analysis was based on high-quality cardiorespiratory polygraphy (PG) recordings (07/2007-03/2016) that were re-analyzed using 2012 American Academy of Sleep Medicine criteria, with differentiation of apneas and hypopneas as obstructive or central...
