American Heart Association: July 10, 2012. Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with significant morbidity and cost.1 AF is seen across a wide spectrum of patients, from lone AF without structural heart disease, to the postoperative setting, to patients with significant left ventricular dysfunction and advanced heart failure. AF is […]
American Heart Association: July 6, 2012. Background—Although increased epicardial adipose tissue (EAT) volume is known to be associated with increased prevalence of atrial fibrillation (AF), the exact mechanisms are unclear. Therefore, we investigated whether EAT locations were associated with high dominant frequency (DF) sites and/or complicated fractionated atrial electrogram (CFAE) sites during AF. Methods and Results—Three-dimensional […]
Onlinelibrary.wiley.com: 7/3/12. Background:Current definition of persistent atrial fibrillation (PAF) enrolls a heterogeneous population with different atrial fibrillation (AF) exposure and degree of atrial substrate. Study aims were to evaluate acute and long-term results of electrical cardioversion (ECV) and to identify temporal cutoff of previous AF exposure to reclassify PAF in subgroups with different chance of […]
Medicalxpress.com: 7/11/12. The new treatment is promising news for people with speech and language disorders that result from diseases within the nervous system. Professor Bruce Murdoch of the Centre for Neurogenic Communication Disorders Research within UQ’s School of Health and Rehabilitation Sciences said preliminary trials of the new treatment were positive in the effective treatment of these speech […]
Stroke.ahajournals.org: July 7, 2012. We describe a novel fluoroscopy co-registered 4D catheter tracking technology (MGT) used for treatment of patients with atrial fibrillation (AF). The aim of the study was to investigate (i) feasibility of non-fluoroscopic catheter manipulation within dynamic left atrial chamber models, (ii) integration of the technology into an established electroanatomical mapping system […]
Stroke.ahajournals.org: July 3, 2012. Bone marrow mononuclear cell (BM-MNC) intra-arterial transplantation improves recovery in experimental models of ischemic stroke. We aimed to assess the safety, feasibility, and biological effects of autologous BM-MNC transplantation in patients with stroke. Methods—A single-blind (outcomes assessor) controlled Phase I/II trial was conducted in patients with middle cerebral artery stroke. Autologous […]
American Heart Association: July 5, 2012. Background—The benefits of intravenous tissue-plasminogen activator (tPA) in acute ischemic stroke are time-dependent. Emergency medical services (EMS) hospital prenotification of an incoming patient with potential stroke may provide a means of reducing evaluation and treatment times and improving treatment rates; yet, available data are limited. Methods and Results—We examined 371 […]
Stroke.ahajournals.org: July 5, 2012. Background and Purpose—The purpose of this study was to investigate time delays, adherence to guidelines, and their impact on outcomes in patients with warfarin-associated intracerebral hemorrhage transferred from community emergency departments to a comprehensive stroke center. Methods—We collected demographic, clinical, transfer time, treatment, and outcome data for patients transferred to our […]
Onlinelibrary.wiley.com: JULY 11, 2012. Stroke is a risk factor for dementia and dementia predisposes to stroke. Dementia prevalence in subjects with stroke is comparable with that seen in stroke-free subjects who are 10 years older. Although overall there is heterogeneity between studies of prestroke and poststroke dementia, stratifying by study method and clinical criteria (e.g. inclusion/exclusion […]
Archneur.jamanetwork.com: 7/9/12. Objective To examine the association between day of admission and measures of the quality and safety of the care received by patients with stroke. Design Retrospective cohort study of patients admitted to hospitals with stroke (codes I60-I64 from theInternational Statistical Classification of Diseases and Related Health Problems, Tenth Version) from April 1, 2009, through […]
