Filter by:Patients with hypertrophic cardiomyopathy are being compared to a control group. IMR will be assessed with a pressure wire. Clinical f/u at 3 months and 6 months and a 48 hour holter monitor.
The purpose of this phase 2 open-label pilot study is to evaluate the efficacy, pharmacokinetics (PK), pharmacodynamics (PD), safety, and tolerability of MYK-461 in subjects with symptomatic HCM and LVOT obstruction aged 18-70 years.
This study evaluates mechanisms of arrhythmogenicity in hypertrophic cardiomyopathy, in comparison to patients with well-understood arrhythmogenic substrate (ischemic cardiomyopathy), as well as to individuals free from arrhythmogenic substrate
First, investigators must determine the physiological standards across age classes of myocardial stiffness estimated by Elastography in ultrafast (estimated right ventricular stiffness [VD] and left ventricular [LV]). This will be done in groups of children without heart condition, age group (10 children per group, four age groups [0-1mois, 1 month-1 year 1 year-5 years, 5 years-15years]). Secondly, investigators will evaluate myocardial stiffness Elastography (RV and LV) on different groups of children (same age group) with cardiomyopathy and examine correlations with the conventional parameters of systolic and diastolic function of both ventricles and with myocardial strain values. The total population of the study will be 120 children (40 healthy, 80 patients).
Hypertrophic cardiomyopathy (HCM) is the most frequent genetic cardiac disease characterized by an asymmetric hypertrophic. In two third of patients, an obstruction to blood ejection is observed within the left ventricle which is named left ventricular outflow tract obstruction (LVOTO). This phenomenon can occur at rest or during exercise and is associated with symptoms such as dyspnea, dizziness or chest pain that can significantly limit day life adaptation. To now, medical or interventional treatments such as betablocacker, calcium blockers or septal alcoholisation or surgery present with a limited efficiency. Recent studies from investigators group revealed new concepts about the role of venous return to the LVOTO. Therefore the investigators hypothesis that BX1514M generating a venous vascular constriction, could improve symptoms of HCM patients by reducing LVOTO.
Hypertrophic cardiomyopathy (HCM) is a common genetic cardiovascular disease. Outflow-tract gradient of 30 mmHg or more under resting conditions is an independent determinant of symptoms of progressive heart failure and death. The investigators hypothesize that the electrical approach by dual chamber pacing could improve symptoms and reduce outflow-tract obstruction in a specific sub-group of selected patients with a mechanical hyper-synchronicity. The aim of the study is to identify and describe this phenomenon in HCM with (O-HCM) and without (NO-HCM) outflow-tract obstruction thanks to innovative multi-imaging approach.
The goal is to determine how lifestyle and exercise impact the well-being of individuals with hypertrophic cardiomyopathy (HCM) and long QT syndrome (LQTS). Ancillary study Aim: To understand how the coronavirus epidemic is impacting psychological health and quality of life in the LIVE population
The purpose of this study is to establish initial safety, tolerability, pharmacokinetics and pharmacodynamics of MYK-461 in human subjects. This is a sequential group, single ascending (oral) dose study in NYHA Class I, II, or III patient volunteers aged 18-65 years.
Assessment of wall thickness in hypertrophic cardiomyopathy (HCM) is of diagnostic and prognostic importance given its known association with sudden cardiac death. However, data regarding comparison of imaging modalities for this key measurement is lacking. This study seeks to compare assessment of maximum wall thickness between clinically indicated echocardiography (with and without contrast) and clinically indicated cardiac magnetic resonance imaging.
