Intravenous thrombolysis (IVT) is a standard treatment for anterior (ACS) and posterior circulation stroke (PCS). However, due to the low occurrence of PCS and of intracranial hemorrhage (ICH) in PCS, the knowledge about ICH predictors following IVT in PCS is sparse. Our aim was to identify predictors for ICH following IVT in PCS. The set consisted of 1281 consecutive ischemic stroke (IS) patients treated with IVT, out of which 158 (103 males; mean age 65.6 ± 12.3 years) had PCS. Collected data include baseline characteristics, common stroke risk factors, pre-medication, stroke severity, admission blood glucose level, blood pressure and treatment with intravenous antihypertensive therapy before and during IVT, occlusion of arteries, recanalization rate, time to treatment, and clinical outcome at day 90...

BACKGROUND: In the general population the leading cause of cardioembolic stroke is atrial fibrillation (AF). A silent AF is also the possible cause of many cryptogenic strokes. P wave dispersion (PWD), a predictor of AF, has been proposed as a marker of silent AF occurrence in these strokes. PWD correlates with high-sensitive C-reactive protein levels reflecting the role of inflammation in promoting a slowed and inhomogeneous atrial conduction. Statins have a multitude of additional effects beyond lipid lowering, in particular anti-inflammatory effects that may influence atrial conduction...

Contemporary data on complications and resource utilization after atrial fibrillation (AF) ablation are limited. We evaluated rates and risk factors for procedural complication, rehospitalization, and emergency department visits after AF ablation. We identified all adult patients who underwent isolated AF ablation between 2010 and June 2014 in 2 large integrated health-care delivery systems and evaluated rates of acute inpatient complication, 30-day, and 1-year readmission and emergency evaluation. We used multivariable logistic regression to identify predictors of procedural complications, 30-day readmission, or 30-day emergency department evaluation...

BACKGROUND: The presence of interatrial block (IAB) is associated with the development of atrial fibrillation (AF). The aim of this study was to determine whether P-wave duration and presence of IAB before the implantation of a cardiac implantable electronic device (CIED) are associated with the presence of atrial high rate episodes (AHRE), during long-term follow-up. METHODS: 380 patients (57% men; 75±10 years) were included. IAB was defined according to the International Consensus Criteria...

BACKGROUND: An important challenge in surgical ablation for atrial fibrillation (AF) is the scarcity of publications on credible predictors of long-term success in procedures performed with ablation tools that produce consistently reliable transmural lesions. We examined factors associated with 1-year success and no atrial arrhythmia (AA) recurrence during 1-5 years after surgical ablation for AF. METHODS: Surgical ablation patients with complete rhythm follow-up at 12 months after surgery were followed prospectively (N=743)...

BACKGROUND: When assessing ischemic stroke risk in patients with atrial fibrillation (AF), the CHA2DS2-VASc score is calculated based on the baseline risk factors, and the outcomes are determined after a follow-up period. However, the stroke risk in patients with AF does not remain static, and with time, patients get older and accumulate more comorbidities. OBJECTIVES: This study hypothesized that the "Delta CHA2DS2-VASc score," which reflects the change in score between baseline and follow-up, would be more predictive of ischemic stroke compared with the baseline CHA2DS2-VASc score...

Background: Oral anticoagulant therapy (OAC) to prevent atrial fibrillation (AF)-related strokes remains poorly used. Alternate strategies, such as community pharmacist prescribing of OAC, should be explored. Methods: Approximately 400 pharmacists, half with additional prescribing authority (APA), randomly selected from the Alberta College of Pharmacists, were invited to participate in an online survey over a 6-week period. The survey consisted of demographics, case scenarios assessing appropriateness of OAC (based on the 2014 Canadian Cardiovascular Society AF guidelines) and perceived barriers to prescribing...

INTRODUCTION: Natriuretic peptides are ubiquitously used for diagnosis, follow-up and prognostic assessment in various heart conditions. N-terminal pro-brain natriuretic peptide (NT-proBNP) correlates with aortic stenosis severity, however its significance after transcatheter aortic valve implantation (TAVI) is not well established. AIM: We aimed to assess the prognostic value of NT-proBNP at one year in patients undergoing TAVI. METHODS: This single-center retrospective analysis included 151 patients in whom both baseline and one-month post-procedure NT-proBNP were measured, from 206 consecutive patients undergoing TAVI between November 2008 and December 2014...

BACKGROUND: Current evidence suggests that a higher red blood cell distribution width (RDW) may be associated with increased risk of atrial fibrillation (AF) development. Given that some controversial results have been published, we conducted a systematic review of the current literature along with a comprehensive meta-analysis to evaluate the association between RDW and AF development. METHODS: We performed a systematic search of the literature using electronic databases (PubMed, Ovid, Embase, and Web of Science) to identify studies reporting on the association between RDW and AF development published until June 2016...

Results from several recent studies in chronic lymphocytic leukemia (CLL) have demonstrated an association between ibrutinib exposure and the development of atrial fibrillation, estimated incidence of 11% with long-term follow up. This is a common cause of ibrutinib discontinuation. Risk factors for atrial fibrillation include advanced age, hypertension (HTN), mitral valve disease (MVD), left atrial remodeling, coronary artery disease (CAD) and risk factors for cardiovascular dysfunction We conducted a retrospective case control study using the presence of left atrial abnormality identified on pre-ibrutinib EKGs, defined as either (1) Lead II-bifed p wave, with 40 mcsec between peaks for ≥ 2...

Atrial fibrillation (AF) is the most common clinically relevant arrhythmia. AF is a strong independent risk factor for the subsequent development of heart failure (HF). HF and AF can interact to perpetuate and exacerbate each other. Soluble ST2 (sST2) is a biomarker of cardiomyocyte stretch that is useful in the diagnosis and prognosis of HF. Its role in the field of AF has not yet been well investigated. We studied the concentration of sST2 in a cohort of 174 subjects (62.1% men; mean age, 65.6 ± 10.3 years [± standard deviation (SD) ]) with nonvalvular AF and 116 age-matched patients with sinus rhythm (SR)...
