Filter by:Cardiomyopathy is a disease of the heart muscle. It is rare, but it can be serious. Cardiomyopathy in children can result in death, disability, heart transplantation or serious heart rhythm disorders. Natural substances in the blood called cardiac biomarkers can be measured in the laboratory and could be a less invasive way (compared to echocardiograms or MRIs) to detect heart dysfunction in children with cardiomyopathy. Little is known about how useful and valid cardiac biomarkers are in the diagnosis and determination of the symptoms in children with cardiomyopathy. The long-term goal of this project is to study how helpful measuring cardiac biomarkers in children with cardiomyopathy is to their doctors in managing the care of these patients as well as improving their overall health. Measures of these cardiac biomarkers could help doctors in determining how best to care for a child with cardiomyopathy, including when to consider heart transplantation as a treatment option.
Cardiomyopathy in children is a serious disease which can result in death, disability, heart transplantation or serious heart rhythm disorders. Doctors know little about the causes of cardiomyopathy but would like to learn more. In fact, up to 50-75% of cases in children have no known cause. For this reason, the purpose of this study is to identify genes that cause cardiomyopathy or that influence how people with cardiomyopathy do over time. These findings could improve disease prevention, surveillance, early management, and prognosis.
The primary goal of the study is to measure in the intact human heart, the alterations in gene expression over time that are associated with reverse remodeling in response to β-blockade. The second goal is to investigate the signaling mechanisms which in turn are responsible for these changes in gene expression, and the third goal is to determine the relationship between intrinsic systolic dysfunction and remodeling of the left ventricle. This will be accomplished by measuring ventricular size, function, and gene expression in myocardial tissue samples obtained by percutaneous biopsy prior to initiation of β-blockade and at 3 and 12 months after start of therapy. The specific Aims and Hypotheses to be tested are: 1. Aim: Determine the changes in gene expression associated with changes in intrinsic systolic function and with functional decompensation in the intact, failing human heart. a. Hypothesis: Changes in the expression of select genes precede or accompany changes in left ventricular systolic function in humans with idiopathic dilated cardiomyopathy (IDC). 2. Aim: Identify signaling mechanisms responsible for alterations in expression of key genes involved in mediation of ventricular hypertrophy or contractile dysfunction. a. Hypothesis: Myocardial-failure-associated regulation of select messenger ribonucleic acids and proteins are related to left ventricular wall stress and neurohormonal signaling. 3. Aim: In the relationship between contractile dysfunction and dilatation/remodeling, determine the relationship between contractile dysfunction and structural remodeling. b. Hypothesis: the contractile dysfunction is primary and structural remodeling secondary.
CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
The investigators will evaluate the determinants of cerebral impairment in patients with non-ischemic heart failure compared to controls, and its relation to cognitive function. They hypothesize that patients with heart failure have impaired brain perfusion and hemodynamic factors are associated with cognitive dysfunction.
The purpose of this study is to determine the safety and clinical effectiveness of umbilical cord mesenchymal cells transplanted by intravenous infusion in patients with heart failure.
The MedSeq™ Project seeks to explore the impact of incorporating information from a patient's whole genome sequence into the practice of clinical medicine. In the extension phase of MedSeq we are attempting increase our participant diversity by increasing targeted enrollment of African/African American patient participants.
Despite the recent advances in medical and surgical treatment, heart failure resulting from ischemic cardiomyopathy (ICM) remains the leading cause of cardiovascular mortality. Ischemic dilated cardiomyopathy(ICM) is defined as abnormally enlarged left ventricular (LV) cavity with documented poor LV function as a result of severe coronary artery disease (CAD). LV remodelling which is inevitable after an infarct has been postulated to contribute largely to the poor outcome of patients with ICM, therefore prevention of LV remodelling is the goal for the treatment in patients with severe CAD. Cell therapy represents a novel therapeutic strategy for treating cardiac diseases including severe CAD and heart failure. A type of stem cells known as mesenchymal stem cells(MSCs)can be isolated from bone marrow.This study aims to test the differentiation potential and therapeutic capacity of MSC from severe CAD patients after intracoronary implantation in an ischemic myocardial environment in Malaysian population.
This study is designed to assess the efficacy, safety and tolerability of ixmyelocel-T compared to placebo (vehicle control) when administered via transendocardial catheter-based injections to patients with end stage heart failure due to IDCM, who have no reasonable revascularization options (either surgical or percutaneous interventional) likely to provide clinical benefit.
This is a multicentre European double-blind,randomized and controlled trial with 2 parallel groups (1 study medication, 1 placebo) in order to analyse the impact of ACE inhibitors (ACEi) in subjects who carry a mutation but have not yet developed DCM (dilated cardiomyopathy). Objective of the trial: Study the impact of ACE inhibitors (ACEi) in subjects who carry a mutation (leading to a genetic form of heart failure) but have not yet developed DCM. Context. Dilated Cardiomyopathy (DCM) is one of the leading causes of Heart Failure due to systolic dysfunction and at least 30% of DCM are of familial/genetic origin, usually with autosomal dominant inheritance, and underlying genes and mutations are increasingly identified. Familial Dilated Cardiomyopathy (fDCM) is characterized by age-related penetrance (or delayed-onset), that means that the cardiac expression of the disease (echocardiographic abnormalities) is usually absent for a long period and progressively appears with advanced age, usually after 20 years of age Hypothesis : ACEi may delay or prevent the occurrence of DCM in these subjects (pre-clinical stage). Expected results: If the hypothesis is confirmed, and as a consequence, the knowledge derived from basic research (genes identification in DCM) will be translated into clinical practice (early identification of subjects at high risk of developing heart failure through predictive genetic testing) with the development of new therapeutic management (early ACEi) that will help to decrease the morbidity and mortality associated with the disease. This will constitute a paradigm of the development of preventive medicine thanks to the development of genetics in the cardiovascular field. Subjects who are concerned are ≥18 years of age and ≤60 years, carry a mutation responsible for DCM and are at a preclinical stage of the disease. Total duration of treatment (perindopril versus placebo) is 3 years. A total number of 200 participants will be enrolled (100 in each group) in 7 centres.
