Active clinical trials for "Cardiomyopathies"

The purpose of this study is to establish initial safety, tolerability, pharmacokinetics and pharmacodynamics of MYK-461 in human subjects. This is a sequential group, single ascending (oral) dose study in NYHA Class I, II, or III patient volunteers aged 18-65 years.

This randomized pilot phase I trial studies the side effects and best method of delivery of bone marrow derived mesenchymal stem cells (MSCs) in improving heart function in patients with heart failure caused by anthracyclines (a type of chemotherapy drug used in cancer treatment). MSCs are a type of stem cell that can be removed from bone marrow and grown into many different cell types that can be used to treat cancer and other diseases, such as heart failure. Bone marrow derived MSCs may promote heart muscle cells repair and lead to reverse remodeling and ultimately improve heart function and decrease morbidity and mortality from progression to advanced heart failure.

This is a prospective clinical trial to determine the optimal QLV interval during implantation to achieve the best possible response from cardiac resynchronization therapy for heart failure patients.

The purpose of this study is to assess the safety and to appraise the efficacy of one cycle of Hepastem (Heterologous Human Adult Liver-derived Progenitor Cells, HHALPC) infusions in paediatric patients suffering from CN or UCD. The study duration: 12 months starting from the day of treatment: 6 months active surveillance and 6 months observation post-infusion.

Pathophysiology of diabetic cardiomyopathy (DCM) is yet unclear and gender differences at baseline and a specific treatment have not been indicated. The investigators already demonstrated the positive impact of phosphodiesterase type 5A (PDE5A) inhibition in men. The investigators' study aims to characterize DCM, measuring molecular and neuroendocrine assessment to relate to intramyocardial metabolism and cardiac kinetic. The investigators will perform a randomized, placebo-controlled, double-blind study enrolling 164 diabetic patients (females and males) with DCM, to evaluate gender responses to 6 months of PDE5A inhibitors (PDE5Ai). The investigators' study will describe gender differences in DCM features. The proposed research will test whether PDE5Ai could become a new target for antiremodeling drugs and to discover a molecular pathways affected by this class of drugs and a network of circulating markers for the early diagnosis, monitoring and prediction of response to treatment of DCM.

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.

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiac disease, is a cause of disability including heart failure, atrial fibrillation, and sudden death, with an annual mortality varying from 1% to 6%. Obstructive sleep apnea (OSA) is extremely common among patients with established cardiovascular disease, including hypertension and atrial fibrillation and when present may contribute to worse cardiovascular outcome. Although patients with HCM do not necessarily have typical characteristics of patients with OSA, such as obesity and increasing age, there is recent evidence that OSA is extremely common among patients with HCM, with a prevalence ranging from 32% to 71%. The presence of OSA among patients with HCM is independently associated with worse structural and functional impairment of the heart, including atrial and aorta enlargement, worse New York Heart Association functional class, and worse quality of life. Therefore, the recognition and treatment of OSA is a new area of research that may impact in the management of patients with HCM.

Dilated cardiomyopathy (DCM) is a poorly understood cause of systolic heart failure and is the most common indication for heart transplantation worldwide. Despite advances in medical and device therapy, the 5-year mortality of patients with DCM remains high. Patients diagnosed of dilated cardiomyopathy with a NYHA functional class of II to IV and left ventricular ejection fraction(LVEF) <35% were selected for randomized controlled study of the efficacy and safety of high dose Renin-angiotensin system (RAS) inhibitor (benazepril or valsartan), in comparison with low dose RAS inhibitor(benazepril or valsartan) and standard beta-adrenergic blocker therapy (metoprolol). The primary endpoint was all cause death or admission for heart failure. Additional prespecified outcomes included all-cause death, cardiovascular death, all-cause admission, heart failure admission. Secondary cardiovascular outcomes included the changes from baseline to the last available observation after treatment in NYHA functional class, quality-of-life scores, LVEF, LVEDD, mitral regurgitation and wall-motion score index assessed by ECG. Adverse events were reported during in-hospital observation and follow-ups.

The WiCS-LV system is an alternative means to providing left ventricular stimulation for Cardiac Resynchronization Therapy (CRT). The purpose of this study is to evaluate the safety and performance of the WiCS-LV System in patients with indications for CRT.

Objective The objective of the study is to assess the structural and functional cardiac effects of treatment with losartan in patients with hypertrophic cardiomyopathy (HCM). Design The study is a randomized, placebo-controlled, double-blinded trial. The follow-up period is 12 months. 130 patients with HCM will be included in predefined subgroups. Genotype positive relatives with borderline hypertrophy (> 13 mm) will also be included. Data on individuals with borderline hypertrophy will be analysed separately from the rest of the cohort. Primary outcome Ventricular hypertrophy assessed as left ventricular mass and maximal wall thickness.
