BACKGROUND: While atrial fibrillation (AF) is an important risk factor for ischemic strokes and mild cognitive impairment (MCI) in Alzheimer's disease, the association between AF and post-stroke cognitive impairment (PSCI), and the factors mediating this association, is unclear. OBJECTIVE: To investigate the role of AF in PSCI, especially in relation to other markers of cerebrovascular disease. METHODS: 445 subjects with mild ischemic stroke without pre-stroke cognitive decline were assessed 3-6 months post-stroke for cognitive deficits...

Patients with atrial fibrillation (AF) are at increased risk of thrombotic events despite oral anticoagulation (OAC). Radiofrequency catheter ablation (RFCA) can restore and maintain sinus rhythm (SR) in patients with AF. To assess whether RFCA improves thrombotic status. 80 patients (71% male, 64 ± 12y) with recently diagnosed AF, on OAC and scheduled to undergo RFCA or DC cardioversion (DCCV) were recruited. Thrombotic status was assessed using the point-of-care global thrombosis test (GTT), before, and 4-6 weeks after DCCV and 3 months after RFCA...

PURPOSE: Hybrid ablation of atrial fibrillation (AF) is a promising treatment strategy for patients with non-paroxysmal AF, although, data regarding mid-term outcomes are limited. METHODS: Patients with persistent or long-standing persistent AF were enrolled. Initially, a thoracoscopic, right-sided, epicardial ablation was performed, with a goal of creating a box lesion on the posterior wall of the left atrium; a novel versapolar radiofrequency (RF) catheter was used...

PURPOSE OF REVIEW: The purpose of this review is to discuss the prevention of venous thromboembolism (VTE) in stroke patients. We discuss use of oral anticoagulation and other interventions for the prevention of VTE. A new class of medications, non-vitamin K antagonist oral anticoagulants (NOACs), have been successfully trialed for the prevention of VTE. We review the data and guidance statements for VTE prevention. RECENT FINDINGS: Warfarin and vitamin K antagonist drugs have been the mainstay of VTE prevention for decades...

BACKGROUND: Nitric oxide (NO) is an effective mediator of ischemic preconditioning (IPC)-induced cardioprotection. Atrial natriuretic peptide (ANP) is downregulated after ovariectomy, which results in reduction in the level of NO. The present study deals with the investigation of the role of ANP in abrogated cardioprotective effect of IPC in the ovariectomized rat heart. METHODS: Heart was isolated from ovariectomized rat and mounted on Langendorff's apparatus, subjected to 30 min of ischemia and 120 min of reperfusion...

INTRODUCTION: The specific protein composition of stroke-causing emboli is unknown. Because ischemic stroke has a varied etiology, it is possible that the composition of the thrombus from which an embolus originated will have distinctive molecular characteristics reflective of the underlying pathophysiology. We used mass spectrometry to evaluate the protein composition of retrieved emboli from patients with differing stroke etiologies and correlated the protein levels to serum predictors of atherosclerosis...

There are two types of tumors found in the cardiac chamber. These are divided into primary intra-cardiac tumors and secondary intra-cardiac tumors. Primary intra cardiac tumors are rare and among them 29% are myxomas. Majority of them are found in the left atrium. Here, we report a case of a myxoma in the right atrium with hepatomegaly and Hepatitis B virus infection. The coexistence of all these conditions is very rare. A 52 years old patient presented with history of shortness of breath on exertion along with fever and generalized weakness for 6 months which aggravated lately for last 2 months...

Ebstein's anomaly is a rare congenital heart disorder, accounting for <1% of all cases of congenital heart disease. It is a congenital malformation of the heart that is characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialization of the right ventricle with a variable degree of malformation and displacement of the anterior leaflet. We report the case of a 25 years old female with Ebstein's anomaly which was associated with Ostium Secundum type of atrial septal defect and WPW syndrome, who presented with dyspnea, palpitations, cyanosis, clubbing and cardiomegaly...

BACKGROUND: Besides hypertension, obesity and the metabolic syndrome have recently emerged as risk factors for atrial fibrillation. This study sought to delineate the development of an arrhythmogenic substrate for atrial fibrillation in hypertension with and without concomitant obesity and metabolic syndrome. METHODS AND RESULTS: We compared obese spontaneously hypertensive rats (SHR-obese, n=7-10) with lean hypertensive controls (SHR-lean, n=7-10) and normotensive rats (n=7-10)...

Atrial fibrillation (AF) is the most common cardiac arrhythmia diagnosed and treated in the world. The treatment of patients' symptoms as well as the prevention of stroke and heart failure is dependent on accurate detection and characterization of AF. A variety of electrocardiographic (ECG) monitoring techniques are being used for these purposes. However, these intermittent ECG monitoring techniques have been shown to under diagnose AF events, while having limited ability to characterize AF burden and density...

BACKGROUND: Atrial fibrillation occurs frequently after open-heart surgery. It is associated with increased morbidity and mortality, longer hospital stays, and increased healthcare costs. Prophylactic administration of colchicine may mitigate post-operative atrial fibrillation (POAF). METHODS: We searched PubMed, ClinicalTrials.gov and CENTRAL databases to identify randomized controlled trials (RCTs) that; (1) compared prophylactic use of colchicine to placebo, or usual care, in patients with sinus rhythm who underwent elective open-heart surgery and (2) reported POAF-incidence...

BACKGROUND: Mobilization of endothelial progenitor cells (EPCs) into circulation from bone marrow in patients with acute myocardial infarction has strong scientific evidence; less is known about EPC mobilization in patients with stable coronary artery disease (CAD). The aim of this study was to investigate the association of stable ischemic heart disease with EPC levels in tissue and blood. METHODS: Fifty-five consecutive patients admitted to a single treatment center for valve or coronary artery bypass grafting (CABG) surgeries were included in the study...

Left atrium (LA) size is a well-studied predictor of atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI). Yet, there is still little agreement on the best imaging technique to size the LA, and on the most appropriate sizing parameter. Volumetric assessment of LA with three-dimensional rotational angiography (3DRA LA volume index) might be a valid alternative to the commonly used transthoracic echocardiography (TTE LA volume index). The aim of our study was to investigate whether LA volume by 3DRA at the time of PVI is able to predict the risk of atrial fibrillation recurrence...

Ahmed et al. showed that atrial fibrillation (AF) was identified in 9.5% in smokers vs 7.8% in non-smokers (p<0.001) and smoking was associated with a 15% increased risk of AF during 10 years follow up in 11,047 participants. However, heterogeneities in the association were observed among subgroups; the association was stronger in young compared to older participants and in those with prior cardiovascular disease compared to without cardiovascular disease, also the association was significant in blacks but not in whites [1]...

OBJECTIVE: The use of preoperative beta-blockers has been used as a quality standard for patients undergoing coronary artery bypass grafting (CABG). However, the benefits of beta-blockers use before CABG remain controversial. We performed a systematic review and meta-analysis to investigate the short-term effects of preoperative beta-blocker use for patients undergoing isolated CABG. METHODS: We searched PubMed, Embase, and the Cochrane Library for English articles published from inception to August 16, 2016...
