Active clinical trials for "Cardiomyopathies"

Inflammatory cardiomyopathies are associated with inflammation and impaired function of the heart muscle and encompass myo- and pericarditis and cardiac sarcoidosis. Due to the heterogeneity of the clinical manifestations, establishing the diagnosis and prediction of outcome is challenging. Specifically for myocarditis, it is associated with acute and chronic heart failure and sudden cardiac death. Cardiac magnetic resonance imaging (CMR) allows imaging of tissue characteristics (i.e. edema and fibrosis). CMR is the primary diagnostic tool in myocarditis and can also be used for differentiating other inflammatory diseases. Beside the presence of edema, also hyperemia/capillary leak, fibrosis and myocardial function can be assessed and quantified. Previous studies demonstrated the prognostic role of CMR features beyond traditional markers of LV function, but are limited to smaller cohorts and single-center studies. Furthermore, CMR is a rapidly developing modality and as new features of the modality become available, additional research is needed to identify which combination of parameters optimize risk stratification of this heterogenous inflammatory cardiomyopathy. Hence, the goal of the registry is to investigate the diagnostic and prognostic role of clinical techniques in inflammatory cardiomyopathies, particularly CMR, and which combination of features provide the highest potential. This analysis will include new advanced CMR techniques but will also assess the role of other techniques that may be more cost-efficient and more widely available, which could be used as a precursor to CMR imaging exams.

The goal of the present study is to determine the occurrence of wild-type and hereditary transthyretin amyloidosis cardiomyopathy among patients with the diagnosis of idiopathic peripheral neuropathy in the setting of a state-of-the-art diagnostic work-up; the investigators believe that the identification of patients with ATTR-CM in this setting can contribute to the early diagnosis of a largely underrecognized condition and, therefore, offer conditions to timely initiation of appropriate therapy with impact on prognosis of patients.

Atrial The treatment of atrial fibrillation (AF) includes 2 axes: the prevention of the cardio-embolic risk and rhythm control. The possibilities for this control are antiarrhythmic drugs and, above all, catheter ablation, an interventional cardiology technique which consists in treating the areas responsible for the initiation and perpetuation of AF by applying radiofrequency energy or cryotherapy to the myocardial tissue. Limited research has been done on the combination of different parameters to manage AF, especially during the initial stage of the disease. A translational and multimodal approach could make it possible to better characterize this pathology and thus, help to adjust the therapeutic management for the patients. The combined analysis of regional electrophysiological, morphological, and functional parameters of the left atrium could make it possible to better detect early atrial cardiomyopathy and predict recurrences of atrial fibrillation.

Human induced pluripotent stem cells (hiPSCs) have driven a paradigm shift in the modeling of human disease; the ability to reprogram patient-specific cells holds the promise of an enhanced understanding of disease mechanisms and phenotypic variability, with applications in personalized predictive pharmacology/toxicology, cell therapy and regenerative medicine. This research will collect blood or skin biopsies from patients and healthy controls for the purpose of generating cell and tissue models of Mendelian heritable forms of heart disease focusing on cardiomyopathies, channelopathies and neuromuscular diseases. Cardiomyocytes derived from hiPSCs will provide a ready source of disease specific cells to study pathogenesis and therapeutics.

Inherited heart conditions (IHCs) can cause young sudden deaths due to a genetic trait that leads to a thickened heart muscle or abnormal heart rhythms. Relatives of an affected person have a 50% chance of inheriting IHCs and this is determined either through a blood test (predictive genetic test) and/or physical tests such as a heart tracing (electrocardiogram), scan (echocardiogram) and exercise test. When patients find out they are affected or are carriers for an IHC, they have numerous questions about medical management, prognosis, lifestyle; as well as experiencing stress and anxiety because of the impact on their health and risk to their family. Based on published studies and interviews, a psychoeducational intervention underpinned by Self-determination Theory was developed to support these patients An uncontrolled study to determine the feasibility of the intervention and outcome measures will be undertaken. Patients with a new IHC diagnosis or a carrier result aged 16 years and older will be recruited from outpatient clinics in London and will be receive the intervention consisting of a disease-specific information leaflet, a personalised lifestyle consideration guide and participation in a 1-hour group session facilitated by a cardiac genetic nurse. Outcome measures to look at degree of self-determination, autonomy support and competence; and heart-related anxiety will be collected at baseline and at 3 months post intervention. Clinical and socio-demographic data will be obtained from medical notes. The feasibility and acceptability of the intervention will be measured by assessment of the study procedures such as recruitment, retention and any adverse events. It is expected that there will be up to 4 consecutive group sessions and feedback from each session will be used to co-design and refine the intervention model for a definitive clinical trial.

The purpose of this study is to learn about the safety of Tafamidis for the treatment of Transthyretin amyloid cardiomyopathy (ATTR-CM) in India. ATTR-CM is a condition that affects people's hearts. Transthyretin is a protein that is made in the liver. In some people this protein stops working and forms clumps called as amyloid. Transthyretin amyloid builds up in heart and stops the heart from pumping properly. This study is seeking for participants who are: confirmed with ATTR-CM. given Tafamidis capsules to be taken by mouth. The safety of Tafamidis capsules will be checked based on side effects. These side effects can happen within 6 months after taking Tafamidis. A side effect is something (expected or unexpected) that you feel was caused by a medicine or treatment you take. The study doctor will collect side effect information and put the information on patient's case form. Follow-up of the patient's will be performed via clinic re-visit or over a call. It is not a rule for the participants to visit the clinic in this study. This study will help to see if Tafamidis is safe.

The goal of this multicenter observational clinical trial is to evaluate the safety and effectiveness of the Cardiohelp System for VA-ECMO in children with cardiac failure. The main question[s] it aims to answer are: What is the safety and effectiveness of the Cardiohelp device for pediatric ECMO? What are the optimal performance specifications of the Cardiohelp device in children? Should the Cardiohelp device be FDA-cleared for children? Children who are receiving the Cardiohelp device will be approached and consented to participate if interested. Participants will undergo a standardized data collection to estimate survival to 30 days and the prevalence of serious adverse events like stroke, bleeding, and hemolysis. Outcomes will be compared to performance goals (PG) derived from the ECMO literature.

Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy that occurs in late pregnancy and early postnatal period, which is mainly characterized by varying degrees of impaired ventricular systolic function and symptoms related to heart failure, and is a serious threat to maternal health. About 50% of patients can achieve complete recovery of cardiac function within 6 months after diagnosis with early standardized treatment, about 30%-40% of patients can have delayed recovery, and about 12.6% of patients have long-term impairment of cardiac function and poor prognosis. However, there are still controversies about whether and when to stop the drug after standardized treatment. The Chinese Society of Cardiovascular Disease of the Chinese Medical Association proposed in the Guidelines for the Diagnosis and Treatment of Dilated Cardiomyopathy in China that patients with PPCM should be considered for gradual withdrawal of the drug after at least 1 year of stabilization of cardiac structure and function recovery. And in the China Heart Failure and Diagnostic and Treatment Guidelines released in the same year, it is proposed that standardized heart failure therapy for patients with peripheral cardiomyopathy should be continued until at least 6 months after the left ventricular function has been fully recovered before gradual discontinuation of the drug. The American Heart Association's 2019 guidelines for perinatal cardiomyopathy remain skeptical about the timing of discontinuation, with some experts suggesting that the drug can be gradually discontinued 1-2 years after cardiac function has recovered, while others still recommend long-term use of the drug to avoid deterioration of cardiac function after discontinuation. At present, there is a lack of large-scale clinical studies on the effect of stopping standardized treatment on the long-term prognosis of PPCM patients, and clarifying whether PPCM patients can discontinue the drug and the timing of discontinuation is of great significance to the long-term prognosis of the patients and even to the rational allocation of the national healthcare resources as a whole.

This project utilizes a novel cardiac pacing approach hypothesized to initiate beneficial cardiac conditioning and remodeling over a period of time.

This study is a multi-center, prospective, single-armed, study designed to evaluate the safety and efficacy of the BioVentrix Revivent TransCatheter (TC) System for left ventricular (LV) volume reduction in heart failure (HF).
