Active clinical trials for "Cardiomyopathy, Dilated"

The Dilated Cardiomyopathy-Cardiac Magnetic Resonance (DCM-CMR) Study is an ancillary study from the parent study, DCM Precision Medicine Study. The rationale for the DCM-CMR study is to leverage cardiac magnetic resonance (CMR) imaging to detect earliest findings of DCM in the at-risk family members enrolled into the parent study.

Dilated cardiomyopathy (DCM) is an increasingly recognized cause of morbidity and mortality with heterogenous etiologies (eg, genetic, environment) and clinical manifestations, characterized by left ventricular (LV) systolic dysfunction and LV or biventricular dilation. Previous publications reported the three-year treated mortality rates remain high at 12%-20% and a reported 5-year mortality rate up to 50%, with death resulting from ventricular arrhythmia leading to sudden cardiac death (SCD) or advanced heart failure (HF). With large fields of view and high spatial resolution, Cardiac magnetic resonance (CMR) is the reference standard for assessing cardiac mass, volume, and function. CMR also provides non noninvasive characterization of the myocardium benefiting to differential diagnosis and risk stratification.

Observational study on patients with dilated cardiomyopathy aims to investigate the correlation between cardiac fibrosis, as indicated by cardiac magnetic resonance, and the prognosis of patients with dilated cardiomyopathy, and further to explore biomarkers for cardiac fibrosis and adverse prognosis of dilated cardiomyopathy. Therefore, endpoints indluding all-cause mortality, cardiovascular death, ventricular arrythmia, non-fatal stroke, non-fatal myocardial infarction, sudden death, successful cardiopulmonary resuscitation will be evaluated.

Finding new ways to diagnose and treat Dilated Cardiomyopathy (DCM) could improve the health and well-being of patients with this condition. The main aim of this research study is to help develop better ways of diagnosing and treating patients with DCM. The information that is collected may help develop tailored treatments for patients with this disease in the future. This research study will recruit patients with DCM from a number of centres across England and follow their health over a period of years. Patients will give some blood samples for a type of genetic test called whole genome sequencing (WGS) to look for genetic changes. Patients will also have a magnetic resonance imaging (MRI) scan of their heart to look for any changes in the heart such as scarring, and check their heart function. The aim of this study is to discover if using WGS and MRI can improve the diagnosis of DCM. Another aim of the study is to look at how genetic changes and scarring in the heart may affect the progress of the disease. Studying patients with DCM may also help the investigators learn more about diagnosing and treating other diseases of the heart. The second aim of this study is to see whether using WGS and MRI scanning can also be useful in other types of heart diseases which might be affected by genetic changes or scarring in the heart.

Biobank is a program which collects biological samples, health information and imaging data from consented patients and stored them at the core facility. These information would be used to study the molecular, imaging and outcome studies of cardiovascular health and disease.

This study seeks to discover clinically useful tests to improve the diagnosis of a rare and serious heart muscle disease caused by mutations in a gene called 'Lamin'. Patients born with lamin gene mutations have apparently healthy hearts initially, they begin experiencing symptoms in their twenties or thirties, and by age 45 the majority have undergone a heart transplant, experienced a major cardiac complication, or have died. Sudden heart rhythm abnormalities are a major cause of sudden death so earlier diagnosis can save lives by enabling timely treatment or implantation of specialised pacemakers (defibrillators). In clinical practice, diagnosis of lamin heart disease currently relies on the genetic test. Very little is known about the detailed imaging features of the hearts of patients with lamin heart disease although advanced echocardiography and cardiac MRI now offer the opportunity to study the health of the heart without the need for radiation.

The overall aim of the study is to explore the energy metabolism of the failing heart. Primary objective is to understand the differences in the energy metabolism in patients with DCM and heart failure compared to matched controls without heart failure. Secondary objectives, is to understand if optimal medical therapy, including sodium-gucose transporter 2 inhibitors (SGLT2i), alter the cardiac metabolism in DCM-patients. The investigators will also examine if changes in cardiac metabolism happens during exercise in patients with DCM. This will be done with invasive measurements of a range of energy substrate metabolites in the coronary sinus of the heart in patients with heart failure due to DCM and controls without heart failure respectively. A range of other clinical characteristics will also be examined to characterize patients and controls.

Clinical evaluation of the CIRCULATE catheter involves intracoronary administration of a typical medical agent (nitroglycerin) and a shown-to-be-safe cell-based agent (CardioCell) in patients with a diagnosis of dilated cardiomyopathy (DCM).

In non-ischemic dilated cardiomyopathy (NIDCM), left ventricular reverse remodeling (LVRR) can be achieved through guideline-directed medical therapy (GDMT). LVRR is defined as an increase in left ventricular ejection fraction (LVEF) of more than 10% in heart failure patients with a baseline LVEF of 40% or less, or an increase in LVEF of more than 40% at follow-up, which is classified as heart failure with improved EF (HFimpEF) according to current guidelines. Several studies have examined the prevalence and predictors of LVRR in NIDCM. However, there is a lack of research on LVRR in the context of contemporary pharmacotherapy. Studies have demonstrated the beneficial effects of ivabradine in heart failure with reduced ejection fraction (HFrEF), improving patients' prognosis. A sub-study of the SHIFT trial indicated that ivabradine may also contribute to cardiac remodeling reversal in patients with HFrEF. However, there is limited evidence exploring the relationship between ivabradine and LVRR, particularly in the context of NIDCM. Consequently, this study is a retrospective, multi-center cohort study aiming to evaluate the impact of ivabradine on LVRR in patients with NIDCM in the current era of medical therapy. Furthermore, by conducting this study, we aim to gain insights into the potential role of ivabradine in promoting LVRR in NIDCM patients receiving contemporary drug therapy.

This is a randomized, double-blind, placebo-controlled study in patients with dilated cardiomyopathy (DCM) due to a mutation of the gene encoding the lamin A/C protein (LMNA). The study will further evaluate a dose level of study drug (ARRY-371797) that has shown preliminary efficacy and safety in this patient population. After the primary analysis has been performed, eligible patients may receive open-label treatment with ARRY-371797.
