Cardiovascular autonomic neuropathy (CAN) is a well known prognostic marker in diabetes. A large angle between the QRS- and the T-wave vector (QRS-T angle) in the electrocardiogram (ECG) has recently been introduced as another marker of poor prognosis. AIM: To assess and compare the long-term predictive power of the frontal plane QRS-T angle with CAN in people with diabetes. METHODS: In 1992-93 people with diabetes in the municipality of Horsens, Denmark, were identified by the prescription method andan age and gender stratified sample of 240 individuals with diabetes were randomly selected...

Exposure to ambient particulate matter (PM) is associated with increased cardiac morbidity and mortality with the elderly considered to be the most susceptible. The purpose of this study was to determine if exposure to PM would cause a greater impact on heart regulation in older DBA/2 (D2) male mice as determined by changes in heart rate (HR) and heart rate variability (HRV). D2 mice at the ages of 4, 12, and 19 months were instilled with 100 µg of PM or saline by aspiration. Before and after the aspiration, 3-min echocardiogram (ECG) samples for HR and HRV were recorded at 15-min intervals for 3 h along with corresponding measurements of homeostasis, such as temperature, metabolism, and ventilation...

Myotonic dystrophy (MD) is a neuromuscular disease with myotonia, progressive weakness, and involvement of CNS, heart, and gastrointestinal system. Excessive daytime sleepiness (EDS) in myotonic dystrophy type 1 (MD1) is related to sleep breathing diseases, restless leg syndrome, periodic limb movements during sleep and narcoleptic-like phenotype. However, authors highlight a central dysfunction of sleep regulation. We describe a 26-year-old, female, MD1 patient with EDS. Sleep diary/actigraphy evidenced two different circadian periods with values of 1442 and 1522 min...

: Ivabradine is a selective and specific inhibitor of If current. With its pure negative chronotropic action, it is recommended by European Society of Cardiology and American College of Cardiology/American Heart Association guidelines in symptomatic heart failure patients (NYHA ≥ 2) with ejection fraction 35% or less, sinus rhythm and heart rate (HR) at least 70 bpm, despite maximally titrated β-blocker therapy. Data supporting this indication mainly derive from the SHIFT study, in which ivabradine reduced the combined endpoint of mortality and hospitalization, despite the fact that only 26% of patients enrolled were on optimal β-blocker doses...

BACKGROUND: Pompe disease is a lysosomal storage disease with an autosomal recessive inheritance characterized by an insufficient activity of the acid alpha-glucosidase enzyme. The incidence varies from 1:40000 to 1:200000 live births and cardiac involvement in adults is rare. Chagas disease is an infection caused by the protozoan Trypanosoma cruzi, in which one-third of the cases progress to the chronic form, and may lead to cardiac involvement, usually from the fifth decade of life onwards...

BACKGROUND: Few therapies are available for the safe and effective treatment of atrial fibrillation (AF) in patients with heart failure. Bucindolol is a non-selective beta-blocker with mild vasodilator activity previously found to have accentuated antiarrhythmic effects and increased efficacy for preventing heart failure events in patients homozygous for the major allele of the ADRB1 Arg389Gly polymorphism (ADRB1 Arg389Arg genotype). The safety and efficacy of bucindolol for the prevention of AF or atrial flutter (AFL) in these patients has not been proven in randomized trials...

The Catheter Ablation Versus Anti-arrhythmic Drug Therapy for Atrial Fibrillation (CABANA,NCT00911508)(1) trial is testing the hypothesis that the treatment strategy of percutaneous left atrial catheter ablation for the purpose of eliminating atrial fibrillation (AF) is superior to current state-of-the-art pharmacologic therapy. This international 140-center clinical trial was designed to randomize 2200 patients to a strategy of catheter ablation versus state-of-the-art rate or rhythm control drug therapy. Inclusion criteria include: 1) age> 65, or ≤65 with≥ 1 risk factor for stroke, 2) documented AF warranting treatment, and 3) eligibility for both catheter ablation and≥ 2 anti-arrhythmic or≥ 2 rate control drugs...

PURPOSE: Atrial fibrillation (AF) is a cardiac arrhythmia characterized by a rapid and irregular heart rhythm. AF types, paroxysmal (PX), persistent (PE) and long-lasting persistent (LSP), requires differences in clinical management. Unfortunately, a significant proportion of AF patients are clinical misclassified. Therefore, our study aim that MALDI-Imaging (IMS) is valuable as a diagnostic aid in AF subtypes assessment. EXPERIMENTAL DESIGN: Patients were clinically classified according guidelines of the European Society of Cardiology...

Ventricular restraint therapy is a non-transplant surgical option for the management of advanced heart failure (HF). To augment the therapeutic applications, it is hypothesized that ASD shows remarkable capabilities not only in delivering stem cells but also in dilated ventricles. Male SD rats were divided into four groups (n = 6): normal, HF, HF + ASD, and HF + ASD-BMSCs respectively. HF was developed by left anterior descending (LAD) coronary artery ligation in all groups except normal group. Post-infarcted electrocardiography (ECG) and brain natriuretic peptide (BNP) showed abnormal heart function in all model groups and HF + ASD-BMSCs group showed significant improvement as compared to other HF, HF + ASD groups on day 30...

Human K2P 17.1 (TASK-4, TALK-2) two-pore-domain potassium (K2P ) channels have recently been implicated in heart rhythm disorders including atrial fibrillation and conduction disease. The functional in vivo significance of K2P 17.1 currents in cardiac electrophysiology remains incompletely understood. Danio rerio (zebrafish) may be utilized to elucidate the role of cardiac K2P channels in vivo. The aim of this work was to identify and characterize the zebrafish ortholog of K2P 17.1 in comparison to its human counterpart...
