PURPOSE: Catheter radiofrequency ablation (RFA) is an effective treatment for symptomatic paroxysmal atrial fibrillation (AF). It has been demonstrated that the multielectrode pulmonary vein ablation catheter (PVAC) has favourable outcomes at 6-12 months post-ablation, but there are only few studies with a long-term follow-up. METHODS: We retrospectively reviewed 77 consecutive PVAC procedures in our centre, from November 2007 to December 2012. RFA was attempted in patients with symptomatic paroxysmal AF (mean age 58...

In the latest American Heart Association/American College of Cardiology/Heart Rhythm Society atrial fibrillation (AF) guidelines, CHA2DS2-VASc replaced the CHADS2 stroke risk assessment to determine prophylactic anticoagulation, reflecting female gender's association with stroke incidence in AF. However, little investigation has been pursued of potential risk factors associated with worsened stroke severity. In this study, we examined patients with AF with ischemic stroke patient characteristics associated with increased stroke severity...

BACKGROUND: In the absence of active management, the stroke risk after a transient ischemic attack (TIA) may be high. Almost 10 years ago, the results of the EXPRESS and SOS-TIA studies called for a more rapid management of TIA patients. The purpose of this study was to investigate the other stroke risks in the longer term, after the implementation of a more active approach to TIA. We also wanted to assess the predictive value of the ABCD2 score in this context. METHODS: Riksstroke is the national stroke registry in Sweden...

OBJECTIVE: To evaluate trends in atrial fibrillation (AF) prevalence in acute ischemic stroke (AIS) and TIA in the United States. METHODS: We used the Nationwide Inpatient Sample to retrospectively compute weighted prevalence of AF in AIS (n = 4,355,140) and TIA (n = 1,816,459) patients admitted to US hospitals from 2004 to 2013. Multivariate-adjusted models were used to evaluate the association of AF with clinical factors, mortality, length of stay, and cost. RESULTS: From 2004 to 2013, AF prevalence increased by 22% in AIS (20%-24%) and by 38% in TIA (12%-17%)...

BACKGROUND: -There are few contemporary data on the mortality and morbidity associated with rheumatic heart disease (RHD) or information on their predictors. We report the two year follow-up of individuals with RHD from 14 low and middle income countries in Africa and Asia. METHODS: -Between January 2010 and November 2012, we enrolled 3343 patients from 25 centers in 14 countries and followed them for two years to assess mortality, congestive heart failure (CHF), stroke or transient ischemic attack (TIA), recurrent acute rheumatic fever (ARF), and infective endocarditis (IE)...

BACKGROUND: Atrial fibrillation (AF) may be related to acute and temporary causes, whether cardiovascular or non-cardiovascular. It remains unclear whether the risk of ischemic stroke is different in this setting, and whether antithrombotic management should be different in these patients. The objective of the study was to describe and compare the risk of stroke in AF patients with and with no such temporary precipitating cause. METHODS: Among 8962 patients with AF seen between 2000 and 2010, we focused our analysis on 4587 patients with non-permanent AF, of whom 740 (16 %) had at least one possible temporary cause of AF...

The combined use of aspirin and oral anticoagulant therapy in patients with atrial fibrillation (AF) and stable coronary artery disease (CAD) has been questioned due to an increased risk of major bleeding with little to no benefit in preventing ischemic events. (1) To better understand patterns and indications for combined antiplatelet and anticoagulant therapy and identify patients who might reasonably be treated with oral anticoagulant (OAC) therapy alone. (2) To perform an updated literature review regarding the use of combined antiplatelet and OAC therapy in patients with AF and stable CAD...

Whether the risk factors for cardiovascular (CV) outcomes are different in primary versus secondary prevention implantable cardioverter-defibrillator (ICD) patients is unclear. We sought to identify predictors of CV outcomes in ICD recipients for primary (G1) versus secondary prevention (G2). Consecutive patients who had ICD implanted during August 2005 to December 2009 were included. The primary outcome was a composite of appropriate shock, acute coronary syndrome, ischemic stroke, coronary revascularization, heart failure exacerbation, CV hospitalization, or all-cause death...

Objectives Atrial fibrillation (AF) is the most common complication after coronary artery bypass grafting (CABG). It is associated with prolonged hospital stay and increased cost. The aim of this study is to investigate the relationship between transfusion of blood derivatives and occurrence of postoperative paroxysmal AF. Materials and Methods From June 2012 to February 2014, 446 patients undergoing CABG with cardiopulmonary bypass (CPB) were prospectively evaluated for occurrence of postoperative AF. Patients and procedural variables were recorded and were associated with the development of new-onset AF with logistic regression analysis...

BACKGROUND AND OBJECTIVE: Atrial fibrillation (AF) is a risk factor for acute ischemic stroke (AIS). In mainland China, little is known of the hospitalization expenses of AIS patients with AF compared to those with normal sinus rhythm (SR). This study compared the itemized expenses of AIS patients with or without AF in a hospital in Huizhou City. METHODS: Patients hospitalized for AIS from March 2014 to March 2015 were enrolled, including 73 with AF and 751 with normal SR...

BACKGROUND AND PURPOSE: The discrimination between paroxysmal and sustained (persistent or permanent) atrial fibrillation (AF) has not been considered in the approach to secondary stroke prevention. We aimed to assess the differences in clinical outcomes between mostly anticoagulated patients with sustained and paroxysmal AF who had previous ischemic stroke or transient ischemic attack. METHODS: Using data from 1192 nonvalvular AF patients with acute ischemic stroke or transient ischemic attack who were registered in the SAMURAI-NVAF study (Stroke Management With Urgent Risk-Factor Assessment and Improvement-Nonvalvular AF; a prospective, multicenter, observational study), we divided patients into those with paroxysmal AF and those with sustained AF...

BACKGROUND: Although atrial fibrillation (AF) is a leading cause of recurrent embolic stroke, secondary AF after stroke has been reported frequently. Because of the different treatment each uses, it is important to detect the exact stroke-etiology. OBJECTIVES: The aim of this study was to compare the embolic stroke in patients with known AF and after-admission AF (AAAF). METHODS: Between October 2002 and July 2009, those who were diagnosed with AF (n=354) were enrolled in our study out of a total of 2026 acute ischemic stroke (IS) patients...

Associations between atrial fibrillation (AF), outcomes, and response to antiplatelet therapies in patients with acute coronary syndrome (ACS) managed medically without revascularization remain uncertain. We examined these associations for medically managed ACS patients randomized to dual antiplatelet therapy (DAPT) using patient data from the TRILOGY ACS trial. DAPT included aspirin plus clopidogrel 75 mg/d or prasugrel 10 mg/d (5 mg/d for those <60 kg or age ≥75 years). Patients receiving oral anticoagulants were excluded...

Essa Hariri, Ahmad Hachem, Georges Sarkis, Samer Nasr
Atrial fibrillation (AF) is the most common form of cardiac arrhythmias and an independent risk factor for stroke. Despite major advances in monitoring strategies, clinicians tend to miss the diagnoses of AF and especially paroxysmal AF due mainly to its asymptomatic presentation and the rather limited duration dedicated for monitoring for AF after a stroke, which is 24 hours as per the current recommended guidelines. Hence, determining the optimal duration of monitoring for paroxysmal atrial fibrillation after acute ischemic stroke remains a matter of debate...

Objective Left atrial enlargement (LAE) may predispose individuals to blood stasis in atrial fibrillation (AF), and thus play a crucial role in thrombogenesis. The D-dimer level is one of the surrogate markers for a hypercoagulable state and reflects thrombus formation in AF. Since the D-dimer level reflects hypercoagulability as well as thrombus and fibrin burdens, LAE could be associated with a D-dimer elevation. However, no studies have explored this association or which factors contribute to increases in the D-dimer levels in patients with AF...

BACKGROUND AND PURPOSE: Patients with a cardioembolic stroke (CES) have worse outcomes than stroke patients with other causes of stroke. Among patients with CES, atrial fibrillation (AF) is a common comorbidity. Mounting data indicate that AF may be related to stroke pathogenesis beyond acute cerebral thromboembolism. We sought to determine whether AF represents an independent risk factor for stroke severity and outcome among patients with CES. METHODS: We retrospectively analyzed patients with acute hemispheric CES included in an academic medical center's stroke registry...
