Active clinical trials for "Cardiomyopathies"

The purpose of this study is To assess the value of dynamics (SVV, PPV) and static indices (GEDVI, ITBVI, CVP) of preload and its combination with contractility (CI,SV, ventricular power, dP/dtmax, CFI, GEF) and lung water indices (ELWI), as predictors of fluid responsiveness in both spontaneously breathing and mechanically ventilated pediatric patients. To assess the value of stroke volume and pulse pressure changes from femoral pulse contour analysis (PiCCO2) during passive leg raising as predictor of fluid responsiveness in pediatric patients. To establish normal and cutoff values of transpulmonary thermodilution (PiCCO2) hemodynamic variables in hemodynamically stables and hemodynamically "normal" patients.

Chronic Heart Failure Analysis and Registry in the Tohoku District 2 (CHART-2 Study) is a large, prospective, hospital-based cohort study to investigate the following: Characteristics of patients with chronic heart failure and prognostic risks of these patients. Characteristics of patients with high risk for heart failure and critical factors which predict the development of symptomatic heart failure in these patients. The incidence and prognostic impact of metabolic syndrome in patients with chronic heart failure. The association between metabolic syndrome and the development of symptomatic heart failure.

The primary hypothesis of the study is that treatment with AT1-R antagonist in patients with nonobstructive form of HCM will be first save, second will cause regression of myocardial hypertrophy.

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.

The investigators have created a way of quickly collecting information in a large scale young population regarding the presence of some severity indicators that may allow us to classify them into: seemingly "low risk" and possible "elevated risk" for the presence of heart disease. It would have to be a short questionnaire, in order to receive a great adherence but that could simultaneously provide precise information, with an adequate description of symptoms and warning signs, in a way that a triage in the young adult population could be performed in the general young adult population in order to select individuals with an indication for personalized clinical evaluation and possible need of complementary diagnostic means. Based on this premise the investigators have developed a fast-response questionnaire named the Sudden Cardiac Death Screening Of risk factorS (SCD-SOS). This questionnaire has already been tested in a population of approximately 1500 young adults, and some changes have been introduced in order to refine its performance. To best of the investigators knowledge, there are no large scale European surveys estimating the prevalence of cardiac disease and associated clinical symptoms in a non-selected (non-athlete) population of this age group. Purpose: To screen a young adult population from central regional of Portugal for heart disease possibly associated to a high risk of Sudden Cardiac Death (SCD). To determine the national prevalence of clinical symptoms of heart disease and of heart disease with increased risk for SCD in this age group. To detect young adults in risk of SCD and with an indication for evaluation by a cardiologist, and possible need of: medical treatment electrophysiologic (EP) study and percutaneous ablation an implantable cardiovertor defibrillator a pacemaker other type of specialized cardiac intervention

Chronic severe mitral regurgitation can lead to symptoms and left ventricular dysfunction. The purpose of this study is to prospectively follow patients with non-ischaemic cardiomyopathy who are eligible for mitral valve repair surgery and primarily measure the quality of life through the Minnesota Living with Heart Failure Questionnaire & the Kansas City Cardiomyopathy Questionnaire.

The purpose of this study is to determine the genetic basis of cardiomyopathies and heart failure.

The purpose of this project is to evaluate parameters of diastolic dysfunction assessed by clinical echocardiogram in patients who have had recovery of systolic function.

COVID-19 is associated with complications including ARDS and myocardial injury, which informs prognosis and patient outcome. The laboratory plans to perform immunophenotyping of peripheral T-cells in patients with COVID-19 and complications (ARDS, ITU admission, myocardial injury) and map this against clinical patient outcomes. The aim is to determine if there is a specific T-cell immunophenotype associated with COVID-19 and/or complications, which can be used to inform prognosis and potential therapies.

Cardiac amyloidosis describes a process by which abnormally folded proteins infiltrate the heart tissue. Given the insidious nature of this disease process, diagnosis is often too late for a meaningful intervention. Advances in the treatment of the amyloidoses have improved outcomes for patients with these conditions. The focus of this study is to identify the involvement of the heart, most closely associated with mortality, so that aggressive management can be instituted improving prognosis.
