The purpose of this study was to determine whether the heart in large mammals contains cardiac progenitor cells that regulate organ homeostasis and regenerate dead myocardium after infarction. We report dog possesses a stem cell pool characterized by undifferentiated are self-renewing, clonogenic, multipotent. These clonogenic early committed progeny possess hepatocyte growth factor (HGF)–c-Met an insulin-like 1 (IGF-1)-IGF-1 receptor system can be activated induce their migration,...

Direct oral anticoagulants (DOACs) reduce the rate of thromboembolism in patients with atrial fibrillation but benefits and risks survivors intracerebral haemorrhage are uncertain. We aimed to determine whether DOACs risk ischaemic stroke without substantially increasing recurrent haemorrhage. PRESTIGE-AF is a multicentre, open-label, randomised, phase 3 trial conducted at 75 hospitals six European countries. Eligible were aged 18 years or older spontaneous haemorrhage, fibrillation, an...

Background — Cell replacement therapy with stem cells able to differentiate into cardiomyocytes has been discussed as a method for remodeling damaged myocardium. A physiological or pathophysiological situation in which this phenomenon might be relevant is not known. We studied the origin of myocardial biopsies male patients that had undergone sex-mismatched cardiac transplantation determine whether containing Y chromosome (and therefore being recipient origin) are cardiomyocytes. Methods and...

Hyperaldosteronism is associated with an increased prevalence of atrial fibrillation (AF). However, it unclear whether this the consequence altered haemodynamics or a direct aldosterone effect. It was aim study to demonstrate load-independent effects on structure and electrophysiology.Osmotic mini-pumps delivering 1.5 µg/h were implanted subcutaneously in rats (Aldo). Rats without treatment served as controls. After 8 weeks, surface electrocardiogram, inducibility AF, pressures recorded...

Up to 40% of patients demonstrate endoscopically detected asymptomatic esophageal lesions (EDEL) after atrial fibrillation ablation.Patients undergoing first ablation and postinterventional endoscopy were included in the study. Occurrence perforating complications during follow-up was related documented EDEL (category 1: erythema/erosion; category 2: ulcer). In total, 1802 underwent procedure between January 2013 August 2016 at our institution. Out this group, 832 (506 male patients, 61%;...

Abstract Artificial intelligence (AI) is developing rapidly in the medical technology field, particularly image analysis. ECG-diagnosis an analysis sense that cardiologists assess waveforms presented a 2-dimensional image. We hypothesized AI using convolutional neural network (CNN) may also recognize ECG images and patterns accurately. used PTB database consisting of 289 ECGs including 148 myocardial infarction (MI) cases to develop CNN MI ECG.

Introduction “Single shot” ablation devices to treat symptomatic atrial fibrillation have been engineered over the last years. Safety and efficacy also includes subclinical complications only detected with esophageal endoscopy or cerebral MRI in asymptomatic patients. We studied acute safety profile of a novel multipolar irrigated RF catheter (nMARQ™ ) . Methods Results Forty‐three patients underwent pulmonary vein isolation (PVI) using device. Patient baseline procedural characteristics...

Abstract CD117-positive cells contributing to cardiac cell turnover in normal and pathological conditions have recently been described adult human heart. Since the precise spatial temporal expression of extracellular matrix proteins their receptors is critical for organ formation, we compared distribution primitive hearts with ischemic cardiomyopathy, respect localization laminin integrin isoforms. In hearts, were significantly more numerous than hearts. They localized mainly atria up...

Although hyperthyroidism predisposes to atrial fibrillation, previous trials have suggested decreased triiodothyronine (T3) concentrations be associated with postoperative fibrillation (POAF). Therapy thyroid hormones (TH), however, did not reduce the risk of POAF. This study reevaluates relation between hormone status, electromechanical function and POAF.Thirty-nine patients sinus rhythm no history or disease undergoing cardiac surgery were prospectively enrolled. Serum thyrotropin, free...

Oesophageal probes to monitor luminal oesophageal temperature (LET) during atrial fibrillation (AF) catheter ablation have been proposed, but their effects remain unclear. Aim of this study is evaluate the an probe with insulated thermocouples. Patients symptomatic, drug-refractory paroxysmal or persistent AF who underwent left radiofrequency (RF) were prospectively enrolled. ablated using a single-tip RF contact force catheter. An intraluminal was used in Group 1. In 2, patients without LET...

Inhibition of the angiotensin-converting enzyme (ACE) prevents maladaptive cardiac remodelling. Endothelial progenitor cells (EPC) from bone marrow contribute to endothelial repair and neovascularization, effects that are potentially important during We hypothesized ACE inhibitors may exert beneficial pressure-induced myocardial hypertrophy by regulating cell function.
