Approximately 30-40% of patients with non-ischaemic dilated cardiomyopathy (DCM) undergo significant left ventricular reverse remodelling in response to guideline-directed therapies. This is characterised by improvement in systolic dysfunction and regression of left ventricular dilatation. In some patients, extensive left ventricular reverse remodelling is accompanied by resolution of symptoms and normalisation of cardiac biomarkers, resulting in a state of clinical remission. The mechanistic drivers behind left ventricular reverse remodelling and clinical remission are poorly understood. Current techniques to predict ventricular remodelling trajectory and clinical remission in patients with recent-onset DCM are limited. The purpose of this study is to characterise predictors and markers of left ventricular reverse remodelling and clinical remission in patients with recent-onset DCM using molecular markers, genetics and advanced CMR imaging.
The QUALIMYORYTHM trial is a multicentre controlled study, aiming to assess health-related quality of life (HRQoL) of 107 children aged 6 to 18 years old with inherited cardiac arrhythmia (long QT syndrome, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia, or arrhythmogenic right ventricular dysplasia), or inherited cardiomyopathies (hypertrophic, dilated, or restrictive cardiomyopathy), and to compare the results to those of 107 age and gender-matched healthy subjects. The secondary objective is to assess, in this population, the HRQoL according to disease characteristics, level of physical activity, exercise capacity, and socio-demographic data. Participants will wear a fitness tracker for 2 weeks.
Use lay language. Current guidelines regarding physical activity in patients with inherited arrhythmia and cardiomyopathy are mostly dedicated to adult patients, with a special focus on sports competition. Their application to the pediatric population has been scarcely evaluated. Physical activity is well known for its health benefits but may be dangerous in this population, which leads to confusion within the medical community and among patients. Actual physical activity of children with such inherited cardiac disorders is unknown. This study aimed to assess the level of physical activity in children with inherited arrhythmia and cardiomyopathy, and the adherence to the current European guidelines on the subject. Secondary objectives aimed to assess through a qualitative analysis the impact of the disease on physical activity and daily life in this population. The level of physical activity and adherence to current guidelines will be determined from interviews between the patient and the principal investigator. Each patient will be questioned in order to explore the experiences, motivations and feelings of participants regarding physical activity. The standardized questionnaire was created by the principal investigator and members of the clinical research team. The investigators believe that many children practice physical activity outside the current guidelines and hope to identify the main determinants of physical activity in this population.
- To determine normal T1 and T2 values of the liver, and to assess the impact of age and gender - To determine the relation between markers of right heart decompensation and T1/T2 values of the liver in patients with pulmonary hypertension, patients with dilated cardiomyopathy, and patients with constrictive pericarditis (or constrictive physiology) - To determine inter/intra-observer reproducibility for liver T1/T2 assessment - To test/develop multi-feature texture analysis for T1/T2 analysis of the liver and implement machine learning to derive indicative features (MR-derived measures only vs combined with other clinical readouts)
The purpose of this study is to optimize the complex treatment of chronic heart failure of non-ischemic etiology by supplementing umbilical cord mesenchymal stem cells to the standard drug therapy.
The aim of this study was to determine the effects of respiratory muscles training on cardiopulmonary parameters and quality of life in patients with dilated cardiomyopathy (DCM). It was a randomized control trial conducted on the calculated sample size of 22 patients divided into 2 groups. Study was conducted at Shifa International Hospital Islamabad. Clinically stable, diagnosed cases of DCM aged 30 to 60 years were included in the study. Outcomes of study were ejection fraction, Left ventricular (LV) End systolic dimensions, LV End diastolic dimension, lung volumes and capacities and quality of life. Data was analyzed on Statistical Package for the Social Sciences (SPSS) version 21. .
Chronic heart failure (CHF) is one of the major causes of death in Western societies. Evidence has accumulated that functionally active autoantibodies directed against the beta1 adrenergic receptor (β1 AAb) are of pathophysiological relevance for the development and progression of cardiomyopathy and associated CHF. BC 007 is under development for targeted neutralisation of autoantibodies directed against G protein coupled receptors, including β1 AAb. This is an open label, three-centre, randomised phase 2a study in participants with chronic HFrEF. The study will evaluate whether BC 007 causes a persistent neutralisation of the β1 AAb demonstrated by a negative β1 AAb status up to 12 months. Participants will be randomised in a 2:1 ratio to the treatment arm (BC 007) or the control arm (untreated). Treatment is repeated once up to month 11 if the participant's β1 AAb were not neutralised after 1st dosing on day 1 or reoccur.
Heart failure affects over 25 million people worldwide and nearly 7 million adults in the United States alone. Nearly 25% of patients with heart failure have worsened disease burden from dyssynchronous ventricular contraction due to abnormal electrical impulse propagation. These patients may benefit from cardiac resynchronization therapy (CRT) where contraction between the ventricles is coordinated by simultaneous electrical stimulation of the right and left ventricles. In animal models, CRT changes molecular and cellular biology by improving myofilament function, ion channel regulation, beta-receptor signaling, and overall mitochondrial energetics. In randomized clinical outcomes trials, the use of CRT further reduced the incidence of heart failure events and improved overall mortality. However, nearly 75% of patients with heart failure have synchronous ventricular contraction and therefore do not qualify for CRT. CRT profoundly alters underlying molecular and cellular biology as a result of the transition from dyssynchronous to resynchronized contraction, enhancing myocyte function and adrenergic responsiveness. The investigators previously hypothesized CRT-like benefits could be achieved in otherwise synchronous heart failure by purposely inducing dyssynchrony for several hours each day and then reversing this for the remainder of the time. The investigators termed this pacemaker induced transient dyssynchrony, or PITA, and tested its impact in a canine dilated cardiomyopathy model. Following several weeks of rapid atrial pacing to induce heart failure in the animals, the investigators compared implementing 4-weeks of PITA - consisting of dyssynchronous rapid right ventricular pacing for 6 hours each night and atrial pacing for the remaining time - to animals that always received rapid atrial pacing. The fast rate is used to generate a heart failure phenotype. PITA improved chamber dilation, increased beta-adrenergic responsiveness and contractile function, and improved myofiber structure compared to heart failure canine controls. While first tested in an intact conscious translational model, no study has yet investigated PITA in humans. This pilot research protocol tests the feasibility, safety, and tolerability of PITA in humans with dilated cardiomyopathy. The study will leverage pre-existing Medtronic (Mounds View, MN) pacemaker/defibrillators implanted in dilated cardiomyopathy patients based on current clinical guidelines. If successful, this study will allow for a larger, first-in-human study to assess indexes of left ventricular function in dilated cardiomyopathy patients with PITA.
We examined the feasibility and reliability of a combined echocardiographic and right heart catheterization (RHC) approach for right ventriculo/arterial (R-V/A) coupling assessment in HF patients with dilated cardiomyopathy (D-CMP).
