Arrhythmia susceptibility in a rat model of acute atrial dilation

In conclusion, CV decrease is not sufficient to promote arrhythmias; enlargement of atrial surface is essential to create a substrate for acute reentry-based arrhythmias.

Tatjana PS Abstract Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with increased risk of death, stroke and heart failure. The prevalence and incidence of AF is increasing due to better overall medical treatment, longer survival and increasing incidence of cardiometabolic and lifestyle risk factors. Treatment of AF and AF-related complications significantly increase health-care costs. In addition, use of conventional rhythm control strategies (i.g. antiarrhyhtmic drugs and catheter-ablation) is associated with limited efficacy for sinus rhythm maintenance and serious adverse effe...

Conclusions: At a follow-up time period of 2 years, pump replacement was significantly higher with the axial continuous-flow pump in comparison to the magnetic levitated centrifugal continuous flow circulatory pump. However, no significant difference was observed with the other adverse outcomes.

Abstract Atrial fibrillation is the most common cardiac arrhythmia in western society affecting more than 35 million individuals worldwide annually. It is a common postoperative complication and may also occur spontaneously during general and local anesthesia administration. Aging, diabetes mellitus, hypertension, and cardiovascular diseases including cardiomyopathies, congenital cardiac anomalies, heart failure, myocardial ischemia, pericarditis, previous cardiac surgery, vascular disease, and valvular heart disease are some correlated factors. Beyond age, increased incidence of atrial fibrillation has been corre...

In conclusion, T2D impairs vascular function by dysregulated autophagy. Therefore, autophagy could be a potential target for overcoming diabetic microvascular complications. To What Degree Does Loss of Skeletal Muscle with Age Contribute to Immunosenescence? https://www.fightaging.org/archives/2019/11/to-what-degree-does-loss-of-skeletal-muscle-with-age-contribute-to-immunosenescence/ Sarcopenia, the progressive loss of muscle mass and strength, is characteristic of aging. A perhaps surprisingly large fraction of the losses can be averted by strength training, but there are nonetheless inexorable process...

Hypertension is the most common cardiovascular risk factor and underlies heart failure, coronary artery disease, stroke, and chronic kidney disease. Hypertensive heart disease can manifest as cardiac arrhythmias. Supraventricular and ventricular arrhythmias may occur in the hypertensive patients. Atrial fibrillation and hypertension contribute to an increased risk of stroke. Some antihypertensive drugs predispose to electrolyte abnormalities, which may result in atrial and ventricular arrhythmias. A multipronged strategy involving appropriate screening, aggressive lifestyle modifications, and optimal pharmacotherapy can re...

Cardiac arrhythmias are common after cardiac surgery and have profound sequelae. Bradycardias are typically transient and have reversible causes; however, persistent atrioventricular block is an indicator for permanent pacemaker implantation after valvular surgery. Transcatheter aortic valve surgery is associated with even higher rates of permanent pacemaker implantation. Atrial fibrillation, the most common postoperative arrhythmia, is associated with ischemic stroke, myocardial infarction, congestive heart failure, and short-term mortality. Ventricular arrhythmias have extremely high in-hospital mortality, as well as lon...

Durr, F. PoussetIntroductionFriedreich ataxia (FRDA) is a rare genetic ataxia. The causal mutation is an expanded trinucleotide repeat (GAA) in the frataxin gene. Hypertrophic cardiomyopathy in FRDA is the major cause of early death. Patients with progressive decline of the left ventricular ejection fraction (LVEF) have the worst prognosis. The aim of the study was to evaluate the prognostic value of 2D global longitudinal strain ...
