Relationship between left atrial volume and ischemic stroke subtype

Annals of Clinical and Translational Neurology, 2019
Objective Atrial cardiopathy without atrial fibrillation (AF) may be a potential cardiac source of embolic strokes of undetermined source (ESUS). Atrial volume is a feature of atrial cardiopathy, but the relationship between atrial volume and ESUS ...

Correlation analysis of the relationship between B-type natriuretic peptide and selected echocardiographic parameters in patients with permanent pacemakers

Studia Medyczne, 2016
Introduction: The present study was undertaken to evaluate the practical value of BNP measurements and echocardiographic left ventricular volume index in patients with permanent pacemakers because there are no such reports in the literature.

Retrospective Grid Cells in the Medial Entorhinal Cortex Encode Past Paths During Spatial Navigation

Advanced Science, EarlyView.
Retrospective grid cells are identified in the medial entorhinal cortex, with spatial firing patterns that become most grid‐like when activity is projected onto recently traversed locations. Their coding loses spatial precision in darkness and is disrupted during assisted movement, indicating that entorhinal representations incorporate recent path ...

Evaluation of Left Atrial Volume and Function with Real-Time 3-Dimensional Echocardiography in Peritoneal Dialysis Patients

Turkish Journal of Nephrology
Background: The volume of the left atrium serves as an independent predictor of mortality across a range of medical conditions. Several studies have examined left atrial (LA) changes in dialysis patients using 2-dimensional echocardiogra phy. This study

Left Atrial Myxoma presenting as Stroke-Case Report & Review of Literature [PDF]

, 2011
Left Atrial Myxomas present as a wide variety of symptoms. We describe one such case which initially presented with hemiparesis and was diagnosed as cerebral infarction. On retrospective work up, the main cause was found to be a left atrial myxoma.

Innovative Approach Reveals How Receptors Control G Protein State Equilibria

Advanced Science, EarlyView.
Using conformational specific trFRET biosensors of the Gi protein (depicted at the bottom), the authors show that receptor activation can not only release GDP from the inactive G protein, but can also release GTP from the activated G protein, leading to the reformation of the RG ternary complex.

The Effects Of Short Tıme Rıght Ventrıcular Pacıng On Left Atrıal Mechanıcal Functıons

Indian Pacing and Electrophysiology Journal, 2009
Objectives: Left atrium (LA) plays an important role in left ventricular filling. It is well known that right ventricular apical pacing has unfavorable effects on ventricular systolic and diastolic performance. The aim of this study is to evaluate the LA

Ultrasound assessment of the association between left atrial remodeling and fibrosis in patients with valvular atrial fibrillation: a clinical investigation

BMC Cardiovascular Disorders
Background Advanced heart failure in patients with valvular atrial fibrillation (VAF) poses a significant threat to human health. Noninvasive assessment of left atrial remodeling in various pathological conditions is instrumental in guiding clinical ...
