Active clinical trials for "Cardiomyopathies"

Cardiomyopathy is the most common inherited cardiovascular disease, showing family aggregation, so it has a huge psychological and economic burden on family members. Studying the clinical characteristics of patients with cardiomyopathy is helpful for further diagnosis, treatment and management, which has important clinical and social significance.

This is a single-center, double-arm, open-label, randomized feasibility study that will determine whether a novel clinical decision aid accessed via the electronic health record will be acceptable to both cancer survivors and their cardiologists, will favorably impact appropriate medication use and cardiac imaging surveillance, and will improve clinician and patient decision-making, perception, and behavior towards cardioprotective medication usage and cardiovascular disease imaging utilization.

Takotsubo syndrome (TTS) is characterized by severe left ventricular (LV) dysfunction that gradually recovers, thus leading to the commonly accepted belief that it is a transient and self-limiting condition. Histologically, TTS can be accompanied by severe morphological alterations potentially resulting from catecholamine excess followed by microcirculatory dysfunction and direct cardiotoxicity. The affected myocardium, however, has a high potential of structural reconstitution which correlates with the rapid functional recovery. The lack of persistent morphological changes in TTS has been confirmed by original CMR studies which pointed out that the acute phase of the disease is characterized only by remarkable myocardial edema with no evidence of significant late gadolinium enhancement. Indeed, the absence of LGE in TTS patients has become a common diagnostic criterion in most CMR centers. Although some studies have challenged this notion by reporting delayed hyper-enhancement in TTS patients, the intensity and extent of LGE in the acute phase of TTS are less than usually reported in studies of myocardial infarction. The long-term clinical and functional consequences of an acute episode of TTS are still unclear. A recent spectroscopic investigation has shown that long-term (>1 year) abnormalities in cardiac energetic persist after an acute episode of TTS. Also, a few patients with residual wall motion abnormality in whom LGE fails to resolve (suggesting the acute event resulted in frank infarction) have been reported. However, how often persistent morphologic abnormalities are present after the index episode remains undefined. The possibility exists that fibrosis was undetected at follow-up CMR studies using conventional LGE threshold methods due to the fact that myocardial injury is subtler and there are no confidently recognizable reference regions of normal myocardium. Newer echocardiographic tools (i.e. tissue Doppler) have now the potential to detect persistence of post-TTS LV function abnormalities.

Cardiomyopathies are diseases of the heart muscle. Known genetic factors may account for some cardiomyopathy cases but there is still much to understand about the genetic and environmental causes and how the disease progresses. Finding new ways to diagnose and treat cardiomyopathies could improve the health and well-being of patients with these conditions. This study will collect data from individuals with cardiomyopathy or related heart muscle disease, or with a possible genetic predisposition to cardiomyopathy, and follow them over time to observe the progress of their heart and health. This study will collect DNA, blood samples, and detailed clinical & lifestyle information at the start of the study, and data collected during routine healthcare visits over time. learn what causes cardiomyopathy, and therefore how to treat it understand why cardiomyopathy progresses differently in different people, to improve the ability to recognise who will benefit from different treatments at different times The investigators will collaborate with other centres internationally to collect a large of group of participants with similar cardiomyopathies, providing power to identify new pathways that cause disease and ways of predicting which participants are at risk of having more severe disease.

The purpose of this study is to investigate whether there are differential expressions of molecules in the kallikrein-kinin system (KKS) pathway in septic cardiomyopathy, and to analyze their regulatory mechanisms and gene expression changes.

The goal of the current research is to develop personalized risk prediction for functional mitral regurgitation (FMR) patients through explainable unsupervised phenomapping enriched with advanced cardiac magnetic resonance (CMR) imaging biomarkers, and to determine the CMR predictors of reverse remodeling following modern therapies for FMR. The prospective study entails aiming to recruit 360 adult patients (ages >18 years) with EF 10-50% and FMR RF> 20%, who are clinically referred for CMR evaluation. Patients who enroll in our study will be referred for optimization of mGDMT and will undergo follow-up CMR studies at 6months. NICM patients who are fully medically optimized with significant FMR at the time of the baseline CMR and are referred for Mitraclip treatment will undergo follow-up CMR 6 months from Mitraclip intervention. NICM patients referred for mGDMT optimization, but have persistent or progressive FMR at the time of 6 month follow-up CMR and referred for Mitraclip therapy, will undergo a 2nd follow-up CMR 6 months from Mitraclip therapy.

Peripartum cardiomyopathy (PPCM) is a rare, severe and potentially life-threatening disorder of largely unknown etiology and pathophysiology, with unexplained geographical differences and heterogeneous presentation. We hypothesize that a network-based multidisciplinary strategy integrating clinical and molecular phenotyping of PPCM patients might anticipate diagnosis, optimize treatments, and identify novel mechanisms to achieve the unmet goal of personalized medicine.

This study aims to identify novel inflammatory biomarkers in AC, whether in circulating blood, in situ or as imaging biomarkers to better understand the pathophysiology of the disease and then to determine contribution to the clinical management of patients.

The aim of this study is to explore if STI technology, especially TMAD, plays an important role in evaluating left ventricular longitudinal systolic function and discriminating SICM in patients with sepsis. We also intend to prove that TMAD may have predictive value in patients with sepsis, which is worthy of in-depth study to find strong evidence-based medical evidence for subsequent clinical practical applications.

Status of the research project: The main complications of arrhythmogenic cardiomyopathies (AC) are sudden death, more rarely heart failure. Recently, data are emerging in favor of an associated role of myocardial inflammation and myocarditis in this pathology, but the impact of inflammation on the presentation and prognosis of the cardiomyopathy, as well as its mechanisms, are not clearly elucidated. To date, endomyocardial biopsy is the gold standard for documenting myocardial inflammation. Aim of the research: To evaluate the interest of a new hybrid PET-MR imaging tool for tissue and metabolic characterization of AC associating MRI and 18F-FDG PET, already used in inflammatory pathologies (cardiac sarcoidosis). Project description: Multicentric observational study of 80 patients with genetic AC undergoing PET-MR. Description of the observed profiles and their impact on the phenotype of the cardiomyopathy and its evolution, study of associated immunological mechanisms, correlation with available anatomopathological data. Expected results and perspectives: first non-invasive description of tissue and metabolic phenotype of AC by PET-MR imaging and its prognostic role, basis for pathophysiological and therapeutic research in case of confirmation of the performances of this imaging for the detection of myocardial inflammation.
