Canadian Stroke Best Practice Recommendations: secondary prevention of stroke guidelines, update 2014
Every year, approximately 62 000 people with stroke and transient ischemic attack are treated in Canadian hospitals. The 2014 update of the Canadian Secondary Prevention of Stroke guideline is a comprehensive summary of current evidence‐based recommendations for clinicians in a range of settings, who provide care to patients following stroke. Notable changes in this 5th edition include an emphasis on treating the highest risk patients who present within 48 h of symptom onset with transient or persistent motor or speech symptoms, who need to be transported to the closest emergency department with capacity for advanced...

Atrial Fibrillation Detected after Acute Ischemic Stroke: Evidence Supporting the Neurogenic Hypothesis
Background: It is unknown whether atrial fibrillation (AF) detected after acute ischemic stroke is caused by neurogenic or cardiogenic mechanisms. Based on the potential damage to the autonomic nervous system, neurogenic mechanisms could be implicated in the pathophysiology of newly diagnosed AF. To test this hypothesis, we developed a mechanistic approach by comparing a prespecified set of indicators in acute ischemic stroke patients with newly diagnosed AF, known AF, and sinus rhythm.Methods: We prospectively assessed every acute ischemic stroke patient undergoing continuous electrocardiographic monitoring from 2008 thro...

Left Atrial Dilation and Risk of One-Year Readmission after Embolic Stroke of Undetermined Source
: Structural left atrial and ventricular abnormalities on the electrocardiogram (ECG) and transthoracic echocardiogram (TTE) at the time of ischemic stroke have been associated with morbidity and mortality. Yet, the prognostic impact of the same in embolic stroke of undetermined source (ESUS), a relevant subtype of ischemic stroke with a unique pathophysiology, has not been well studied to date. Our aim was to assess the predictive impact of left atrio-ventricular ECG and TTE abnormalities on one-year hospital readmission after ESUS from an ongoing single center prospective stroke registry in the U.S.

Prognosis of Early-Stage Continuous Electrocardiogram Abnormalities on Patients with Acute Ischemic Stroke
To explore the effects of onset time of electrocardiogram (ECG) abnormalities at an early stage of acute ischemic stroke on patient prognosis. Cardiac dysfunction after stroke is a challenge for clinicians. This is a retrospective study of patients in the neurology departments of 23 hospitals in Shanghai and Wuhan, China.

Cardiac Imaging Within Emergency CT Angiography for Acute Stroke Can Detect Atrial Clots
This study was approved by the ethics committee of the medical faculty of the Ruhr University Bochum. FIGURE 1 Figure 1. Flow chart showing the selection of the study population. Results A total of 59 patients underwent emergency CCTA (Figure 2A) for suspected stroke, of which 44 received the final diagnosis ischemic stroke. There were 17 patients who had ischemic stroke or TIA and known or newly diagnosed atrial fibrillation (Table 1; mean age: 77.5 years, standard deviation: 8.4 years; 53% female). As hypothesized, intracardiac thrombi could be visualized: once in an artificially occluded left atrial appe...

Diagnosis of atrial fibrillation after stroke and transient ischaemic attack: a systematic review and meta-analysis
Publication date: Available online 4 March 2015 Source:The Lancet Neurology Author(s): Luciano A Sposato , Lauren E Cipriano , Gustavo Saposnik , Estefanía Ruíz Vargas , Patricia M Riccio , Vladimir Hachinski Background Among patients with atrial fibrillation, the risk of stroke is highest for those with a history of stroke; however, oral anticoagulants can lower the risk of recurrent stroke by two-thirds. No consensus has been reached about how atrial fibrillation should be investigated in patients with stroke, and its prevalence after a stroke remains uncertain. We did a systematic review and meta-analysis to estimat...

The effect of postoperative stroke and myocardial infarction on long-term survival after carotid revascularization
Introduction: The largest randomized controlled trial that compared the efficacy of carotid endarterectomy (CEA) with carotid artery stenting (CAS) showed equivalent outcomes for the composite end point of postoperative stroke, myocardial infarction (MI), or death. However, CAS had a higher risk of postoperative stroke, and CEA had a higher risk of MI. We hypothesize that there is a differential association of postoperative stroke, compared with that of postoperative MI, with reduced long-term survival after carotid revascularization when compared with neither complication.Methods: The Vascular Study Group of New England d...

Left atrial volumes and associated stroke subtypes
This study is a standardized review of 633 patients admitted to the stroke service of a tertiary care hospital following a standardized stroke investigation and management pathway. Stroke subtypes were characterized using the Causative Classification System, using the hospitals online radiologic archival system with CCS certified stroke investigators. Patients with two mechanisms were excluded. Results: Patients with cardioembolic stroke had a higher proportion of atrial fibrillation (p

Association of ventricular arrhythmia and in-hospital mortality in stroke patients in Florida: A nonconcurrent prospective study
Abstract: Stroke remains one of the leading causes of death in the United States. Current evidence identified electrocardiographic abnormalities and cardiac arrhythmias in 50% of patients with an acute stroke. The purpose of this study was to assess whether the presence of ventricular arrhythmia (VA) in adult patients hospitalized in Florida with acute stroke increased the risk of in-hospital mortality. Secondary data analysis of 215,150 patients with ischemic and hemorrhagic stroke hospitalized in the state of Florida collected by the Florida Agency for Healthcare Administration from 2008 to 2012. The main outcome for th...

Long-term Arrhythmia Monitoring in Cryptogenic Stroke: Who, How, and for How Long?
Authors: Montalvo M, Ali R, Silver B, Khan M Abstract Cryptogenic stroke and transient ischemic attack (TIA) account for approximately one-third of stroke patients [1]. Paroxys-mal atrial fibrillation (PAF) has been suggested as a major etiology of these cryptogenic strokes [2, 3]. PAF can be difficult to diagnose because it is intermittent, often brief, and asymptomatic. PAF might be more prevalent than persistent atrial fibrillation in stroke and TIA patients, especially in younger populations [4, 5]. In patients with atrial fibrillation, anticoagulation provides significant risk reduction [6]. A new generation o...

Utility of Duranta, a wireless patch-type electrocardiographic monitoring system developed in Japan, in detecting covert atrial fibrillation in patients with cryptogenic stroke: A case report
Rationale: Subcutaneous implantable electrocardiographs are highly effective in detecting covert atrial fibrillation (AF) in cryptogenic stroke. However, these invasive devices are not indicated for all cryptogenic stroke patients, and noninvasive improvements over conventional Holter-type ambulatory electrocardiography are needed. We evaluated the clinical application and effectiveness of Duranta (ImageONE Co., Ltd.), a wireless patch-type electrocardiographic monitoring system developed in Japan for chronically ill patients or home-based patients at the end of life. A Duranta device was used to detect covert AF in patien...

Resting Heart Rate and Ischemic Stroke in Patients with Heart Failure
This study is aimed at investigating the relationship between RHR and ischemic stroke in patients with heart failure in sinus rhythm.Methods: We examined 2,060 patients with systolic heart failure in sinus rhythm from the Warfarin versus Aspirin in Reduced Cardiac Ejection Fraction trial. RHR was determined from baseline electrocardiogram, and was examined as both a continuous variable and a categorical variable using quartiles. Ischemic strokes were identified during follow-up and adjudicated by physician review.Results: During 3.5 ± 1.8 years of follow-up, 77 patients (5.3% from Kaplan-Meier [KM] curve) experienced an i...

Left ventricular hypertrophy assessed by electrocardiogram is associated with more severe stroke and with higher in-hospital mortality in patients with acute ischemic stroke
Left ventricular hypertrophy (LVH), assessed by electrocardiogram (ECG), is associated with increased risk for stroke. However, few studies that evaluated whether ECG-detected LVH predicts ischemic stroke severity and outcome. We aimed to evaluate these associations.
