Evaluation of autoantibodies to desmoglein-2 in dogs with and without cardiac disease

Scientific Reports, 13(1).

By: A. Walker*, R. Li* , N. Nguyen *, C. Jauregui *, K. Meurs n , A. Gagnon*, J. Stern* 

MeSH headings : Animals; Dogs; Arrhythmogenic Right Ventricular Dysplasia; Autoantibodies; Dog Diseases / metabolism; Heart Atria; Prospective Studies; Desmoglein 2 / immunology
TL;DR: This prospective study is the first to evaluate dogs of various breeds and cardiac disease state for anti-desmoglein-2 antibodies and found correlation with some measures of disease severity requires further study with larger populations. (via Semantic Scholar)

By: A. Walker*, Y. Ueda n , A. Crofton *, S. Harris * & J. Stern* 

MeSH headings : Administration, Oral; Adrenergic beta-2 Receptor Agonists / administration & dosage; Animals; Arrhythmias, Cardiac / diagnosis; Arrhythmias, Cardiac / genetics; Arrhythmias, Cardiac / physiopathology; Arrhythmias, Cardiac / veterinary; Asymptomatic Diseases; Cardiomyopathy, Hypertrophic / diagnosis; Cardiomyopathy, Hypertrophic / genetics; Cardiomyopathy, Hypertrophic / physiopathology; Cardiomyopathy, Hypertrophic / veterinary; Case-Control Studies; Cat Diseases / diagnosis; Cat Diseases / genetics; Cat Diseases / physiopathology; Cats; Electrocardiography, Ambulatory / veterinary; Female; Genetic Predisposition to Disease; Heart Rate; Male; Mutation; Phenotype; Predictive Value of Tests; Sex Factors; Terbutaline / administration & dosage; Time Factors
TL;DR: This prospective study used AECG to evaluate ectopy and HRV in subclinical HCM cats compared to healthy controls and is the first to implement a pharmacologic cardiac stress test. (via Semantic Scholar)

Comparative Assessment of Heart Rate Variability Obtained via Ambulatory ECG and Polar Heart Rate Monitors in Healthy Cats: A Pilot Study

FRONTIERS IN VETERINARY SCIENCE, 8.

By: E. Grigg *, Y. Ueda n , A. Walker*, L. Hart *, S. Simas* & J. Stern* 

author keywords: cat; physiological stress measures; heart rate; heart rate variability; Holter monitor; Polar H10
TL;DR: This pilot study tested the feasibility of obtaining HRV data from unrestrained cats, using a commercially available cardiac monitoring system (Polar H10 with chest strap), compared with data from a traditional ambulatory electrocardiogram, and results do not support the use of Polar H10 heart rate monitors for studies of HRV in cats.

Reference intervals for radiographic, echocardiographic and N-terminal pro B-type natriuretic peptide values in healthy kittens

JOURNAL OF FELINE MEDICINE AND SURGERY, 23(4), 293–301.

By: C. Gunther-Harrington *, A. Sharpe*, K. Vernau *, Y. Ueda n , E. Montgomery *, J. Surmick*, N. Fernandez *, E. Ontiveros*, A. Walker n, J. Stern* 

author keywords: Vertebral heart score; cardiac thoracic ratio; biomarker; reference interval; radiography; echocardiography
MeSH headings : Animals; Biomarkers; Cats; Echocardiography / veterinary; Female; Heart Murmurs / veterinary; Natriuretic Peptide, Brain; Peptide Fragments; Reference Values
TL;DR: This study establishes RIs for thoracic radiograph assessment, echocardiography and cardiac biomarkers in kittens, which fills a critical gap in the veterinary literature. (via Semantic Scholar)
