Scientists find key gene mutations behind inherited heart disease

LONDON (Reuters) - Scientists have identified the crucial genetic mutations that cause a common heart condition called dilated cardiomyopathy (DCM), paving the way for more accurate diagnosis and screening of high-risk patients.

We present a retrospective review of 13 consecutive children who underwent implantation of VAD between 2001 and 2018 in our center. The median age was 12  years (1–17 years), weight was 45 kg (10–82 kg). Etiologies of heart failure were dilated cardiomyopathy (CMP) (n = 8), myocarditis (n = 2), ischemic CMP (n = 1), restrictive CMP (n = 1) and congenital heart disease (n = 1). Pre-implantation ECMO was used in 5, mechanical ventilation in 4, renal replacement therapy in 2 and IABP in 1. Devices used were: Berlin Heart EXCO...

In conclusion, AF seems to have a higher prevalence in the general population than previously thought, and is mostly associa ted with hypertension, cardiomyopathy and rheumatic heart disease in SSA. It is associated with a high incidence of heart failure and stroke. The management of AF is suboptimal in SSA, especially with a low uptake of oral anticoagulation.This article is protected by copyright. All rights reserved.

In this study we examined whether exposure to BPA for two weeks prior to viral infection and leading up to myocarditis at day 10 altered inflammation in female BALB/c mice housed in standard plastic cages/water bottles with soy-free food and bedding. We found that a human relevant dose of BPA (25µg/L) in drinking water, with an estimated exposure of 5µg BPA/kg BW, significantly increased myocarditis and pericarditis compared to control water without altering viral genome levels in the heart. BPA exposure activated ERa and ERb in the spleen 24 hours after infection and phosphorylated ERa and ERb during myocardit...

AbstractObjectiveMutations in LIM domain binding 3 (LDB3) gene cause idiopathic dilated cardiomyopathy (IDCM), a structural heart disease with a complicated genetic background. However, the association of polymorphisms in theLDB3 gene with susceptibility to IDCM in Chinese populations remains unexplored as dose the impact on clinical presentation.MethodsWe sequenced all exons and the adjacent part of introns of theLDB3 gene in 159 Chinese Han IDCM patients and 247 healthy controls. Then we detected the distribution of polymorphisms in theLDB3 gene in all participants and assessed their associations with risk of IDCM. Addit...

In conclusion, with study of the frailty syndrome still in its infancy, frailty analysis remains a major challenge. It is a challenge that needs to be overcome in order to shed light on the multiple mechanisms involved in the pathogenesis of this syndrome. Although several mechanisms contribute to frailty, immune system alteration seems to play a central role: this syndrome is characterized by increased levels of pro-inflammatory markers and the resulting pro-inflammatory status can have negative effects on various organs. Future studies should aim to better clarify the immune system alteration in frailty, and seek to esta...

Ventricular tachycardia (VT) and VF occur mainly in people with impaired cardiac function and/or ischaemic heart disease, and account for the majority of sudden cardiac deaths worldwide.1 Treatment with anti-arrhythmic drugs such as amiodarone may be at best neutral in terms of mortality and carries significant long-term risks.2,3 While ICDs significantly improve survival for patients with significantly impaired left ventricular ejection fraction (LVEF), the devices also carry risk

The innate immune cells called macrophages are vitally important to the health and function of tissues. They help to coordinate the intricate dance of stem cells, somatic cells, and immune cells that produces tissue regrowth and tissue maintenance. They destroy errant cells and pathogens. They have a variety of other roles as well. But where do macrophages come from? While some macrophages are generated within tissues, it is generally the case that in damaged or diseased tissues, most macrophages were originally monocytes. Circulating monocytes in the bloodstream enter tissues in response to chemical cues and then transfor...

AbstractIschemic heart disease and non-ischemic dilated cardiomyopathy are the most common causes of arrhythmic sudden cardiac death (SCD). Implantable cardioverter defibrillator (ICD) therapy is the only strategy that proved to be effective in preventing SCD in high-risk individuals while the role of antiarrhythmic drugs is limited to symptoms relief. Current guidelines recommend selecting candidates to ICD implantation based on etiology, symptoms of heart failure (NYHA class), and severely depressed left ventricular ejection fraction, but these parameters are neither sensitive nor specific. The review addresses the mecha...
