Active clinical trials for "Cardiomyopathies"

The purpose of this study is to investigate the effects of immunoadsorption and subsequent IgG substitution in patients with dilated cardiomyopathy compared to a control group.

Pathophysiology of Cushing's Syndrome (CS) cardiomyopathy is yet unclear and a specific treatment have not been indicated. It was already demonstrated the positive impact of phosphodiesterase type 5A (PDE5A) inhibition in several models of cardiomyopathy and in a model of endocrine cardiomyopathy due to type 2 diabetes mellitus. In this patients with diabetic cardiomyopathy it was demonstrated an improvement in cardiac kinetic, geometry and performance parameters and reduction of the ambulatory measurement of waist circumference. This represents the first study that evaluate heart remodeling and performance changes and metabolic/immunological/molecular parameters after 5-months of Tadalafil 20 mg in Cushing's Syndrome cardiomyopathy. The proposed research will test whether phosphodiesterase 5A inhibition could become a new target for anti-remodeling drugs and to discover molecular pathways affected by this class of drugs and a network of circulating markers (miRNA) for the early diagnosis of Cushing's Syndrome cardiomyopathy. The investigators hypothesize that: the signal molecules cGMP and cAMP could underlie the hypertrophic/profibrotic triggers related to this model of endocrine cardiomyopathy and that chronic inhibition of PDE5, activating cGMP signaling pathways, could improve cardiac remodeling due to CS; PDE5 inhibition could have a role in lipolytic regulation; neuroendocrine (e.g. natriuretic peptides) and metabolic markers and chemokines (e.g. MCP-1, TGF-ß) might relate with left ventricular remodeling in CS; there are neuroendocrine (e.g. natriuretic peptides), metabolic markers and chemokines (e.g. MCP-1, TGF-ß) related to cardiac disease in CS; miRNA expression [miR-208a, 499, 1, 133, 126, 29, 233, 222, 4454] might relate with left ventricular remodeling in CS;

This was a single center, proof-of-concept (PoC), Phase II study. Patients with histologically confirmed early stage (Stage I, II or III) HER-2 negative breast cancer and scheduled to receive doxorubicin-based (neo)adjuvant therapy to be followed by paclitaxel or docetaxel as per clinical practice. The planned doxorubicin-based chemotherapy treatment consisted of doxorubicin 60 mg/m2 in combination with cyclophosphamide 600 mg/m2 (AC) intravenous (IV) every 2 or 3 weeks for 4 cycles. Patients were scheduled for CMRI and 99mTc-rhAnnexin V-128 imaging (planar and SPECT / CT) at the following visits: Screening/baseline, i.e. 2 weeks prior to initiating AC treatment (Visit 1) After the 2nd and before the 3rd cycle of AC treatment (Visit 2) After the 4th cycle of AC treatment and within 2 weeks (Visit 3) At 12 weeks after the 4th cycle of AC treatment (Visit 4). The imaging procedures were conducted and analyzed. Bloodwork for cardiotoxicity biomarkers (troponin, N terminal pro B-type natriuretic peptide [NT-proBNP]) was performed at each visit.

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 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.

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 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.

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.
