Abstract Background Restrictive cardiomyopathy (RCM) is a common primary cardiomyopathy of cats. However, little information is available regarding prognostic variables in large populations of cats with RCM. Objectives T...

We show that TANGO2 in mammalian cells localizes predominantly to mitochondria and partially at mitochondria sites juxtaposed to lipid droplets (LDs) and the endoplasmic reticulum. HepG2 cells and fibroblasts of patients...

Background: Wearable electrocardiography (ECG) devices such as smartwatches offer a novel means for detecting cardiac arrhythmias, particularly atrial fibrillation (AF), and ST-segment abnormalities. Their role in comple...

Abstract Background Cardiac disease is an important cause of morbidity and mortality in Irish Wolfhounds (IWs), but its prevalence and clinical characteristics in North American IWs are incompletely described. Hypothesis...

Abstract Background Ischemic stroke (IS) remains a leading cause of death and disability worldwide. Stroke–heart syndrome, triggered by acute cerebral ischemia, causes autonomic dysfunction that can result in myocardia...

OBJECTIVE: Patients with chronic kidney disease (CKD) have increased risk for cardiac arrhythmias. Other than comorbidities like diabetes mellitus and cardiovascular disease, factors like acidosis, uremia and electrolyte...

Objective: to evaluate the prevalence of cardiac problems, including myocardial iron deposition, pericarditis, and valvular abnormalities, among people with β-thalassemia and to shed light on the distribution of β-thal...

The occurrence of late potentials in dogs under doxorubicin-induced cardiomyopathy and their relationship with the development of ventricular arrhythmias or sudden death were studied. Seven adult mongrel dogs of both sex...

Abstract Left atrial appendage (LAA) aneurysm is a rare structural abnormality that can predispose to significant complications, including systemic embolism and complex supraventricular arrhythmias. Here, we report a 44-...

Abstract Background Cardiac catheterizations in horses are mainly performed in the right heart, as access to the left heart traditionally requires an arterial approach. Transseptal puncture (TSP) has been adapted for hor...

Left ventricular hypertrophy (LVH) is an enlargement of the left ventricle caused by chronically increased hemodynamic load, such as arterial hypertension or aortic stenosis. In the initial stages, LVH has a protective n...

Background. Long QT Syndrome (LQTS) is a hereditary cardiac channelopathy that predisposes individuals to malignant arrhythmias and sudden cardiac death. In athletes, physiological cardiac adaptations can mask or mimic L...

Abstract Trypanosoma cruzi infection in dogs can cause heart failure and sudden death with few treatment options available. A litter of 4 dogs living in a T cruzi endemic area were randomized to prophylaxis and nonprophy...

Abstract Background Distal renal tubular acidosis (dRTA) is an uncommon renal tubular disorder marked by impaired distal nephron acid excretion, resulting in hyperchloremic metabolic acidosis, persistent alkaline urine, ...

Background: Drug-resistant tuberculosis (DR-TB) is a major public health challenge in Sub-Saharan Africa (SSA), worsened by high HIV prevalence and limited healthcare infrastructure. Bedaquiline, a cornerstone DR-TB trea...

Rhabdomyolysis is a condition of muscle tissue release including after necrosis of muscle due to a direct or indirect muscle injury. Rhabdomyolysis is mostly asymptomatic but hypovolemic shock, cardiac arrhythmias or acu...

Goal: To enable comfortable and non-invasive heart rhythm monitoring, this work aims to reconstruct electrocardiogram (ECG) signals from photoplethysmogram (PPG) signals, eliminating the need for multiple electrode attac...

Current management does not fully prevent arrhythmias in long QT syndrome (LQTS), underscoring a need for novel therapies. Here, we investigated potential beneficial effects of serum/glucocorticoid-regulated-kinase-1 (SG...

Abstract Background Comparisons between smartphone ECG (SpECG) recordings obtained from the right and left sides of the thorax have not been reported in animals. Objectives To evaluate the screening potential of a SpECG ...

L-carnitine (L-C) deficiency seen in chronic hemodialysis (HD) patients may contribute to heart failure and arrhythmias, through damaging the myocardial energy metabolism. In this study, the effect of L-C treatment on le...

ABSTRACT Cardiac arrhythmias are common in horses and can lead to a decline in performance and sudden death. The use of cardiac pacemakers in horses has been poorly investigated, with a scarcity of description and develo...

El clorhidrato de propranolol (ClPr) es un agente bloqueante ß-adrenérgico no selectivo, utilizadoprincipalmente en el tratamiento de la hipertensión, arritmias cardíacas y en angina de pecho y clasificada como de Ri...

El clorhidrato de propranolol (ClPr) es un agente bloqueante β-adrenérgico no selectivo, utilizado principalmente en el tratamiento de la hipertensión, arritmias cardíacas y en angina de pecho y clasificada como de R...

The newly inaugurated Research Resource for Complex Physiologic Signals, which was created under the auspices of the National Center for Research Resources of the National Institutes of Health, is intended to stimulate c...
