Active clinical trials for "Cardiomyopathies"

The purpose of this study is to evaluate the safety and effectiveness of an experimental drug called human allogeneic mesenchymal stem cell therapy.

Atrioventricular node ablation (AVNA) with biventricular (BiV) pacemaker implantation is a feasible treatment option in patients with symptomatic refractory atrial fibrillation and heart failure. However, conduction system pacing (CSP) modalities, including His bundle pacing and left bundle branch pacing, could offer advantages over BiV pacing by providing more physiological activation. The randomized, interventional, multicentric study will explore whether CSP is non-inferior to BiV pacing in echocardiographic and clinical outcomes in heart failure (EF <50%) patients with symptomatic AF and narrow QRS scheduled for AVNA.

Hypertrophic cardiomyopathy (HCM) is the most common inherited monogenic heart disease. There is an abnormal increase in myocardial mass in this disorder that leads to a state of cardiac sympathetic hypertonia, which is involved in disease progression, development of arrhythmias and heart failure. Cardiac sympathetic hyperactivity may constitute a new therapeutic target in HCM patients who persist symptomatic despite conventional treatment. The hypothesis of this project is that renal denervation (a minimally invasive percutaneous interventional therapy with proven efficacy in resistant arterial hypertension) reduces cardiac sympathetic activity in HCM. The SNYPER pilot study is a non-randomized clinical trial with medical devices (proof of concept), in which a renal denervation procedure will be performed in 20 patients with genetically confirmed sarcomeric HCM, severe left ventricular hypertrophy and persistent symptoms. The impact of denervation in reducing the 123I-meta iodo benzyl guanidine (MIBG) washout rate quantified by isotopic tracing (planar imaging and SPECT) at 6 months is established as a primary efficacy objective, and the proportion of renal denervation-related complications as a safety objective. The most relevant secondary endpoints are the outcomes of renal denervation on left ventricular mass (echocardiogram), diastolic function, maximum oxygen consumption (ergospirometer), ventricular arrhythmia burden (Holter), blood pressure (ABPM), N-terminal (NT) Pro Brain Natriuretic Peptide (BNP) and quality of life (KCCQ questionnaire). The results of this study may open the development of a new, technically simple and easily accessible therapeutic line for the treatment of HCM.

The study will enroll 200 women newly diagnosed with peripartum cardiomyopathy within 5 months postpartum in a randomized placebo controlled trial of bromocriptine therapy to evaluate its impact on myocardial recovery and clinical outcomes. Given that bromocriptine prevents breastfeeding, an additional 50 women with peripartum cardiomyopathy excluded from the trial due to a desire to continue breastfeeding but meeting all other entry criteria will be followed in an observational cohort.

The ECMO-RESCUE study is a prospective, multicenter, non-randomized, cohort study. In this study, we aimed to assessed whether VA-ECMO treatment can improve the 30-day survival rate of patients with sepsis-induced refractory cardiogenic shock.

Double blind, randomised, placebo-controlled trial of MitoQ (mitoquinol mesylate) in 106 patients with dilated cardiomyopathy, examining the effect of reducing mitochondrial oxidative stress on myocardial energetics and myocardial function using 31-phosphorus magnetic resonance spectroscopy and cardiovascular magnetic resonance.

The purpose of this Phase 2a study is to establish safety and preliminary efficacy of treatment with danicamtiv in patients with primary dilated cardiomyopathy (DCM) due to MYH7 or TTN variants or other causalities.

The primary objective of this pilot study is to document the percentage achievement in effective HR control (average nighttime HR < 70 bpm) during WCD use in a cohort of female patients with cardiomyopathy in an outpatient setting using continuous heart rate (HR) trends data from the WCD to optimize BB/ivabradine dosage, as compared to a prior historical control.

Heart failure is the primary cause of morbidity and mortality worldwide. Currently drug treatments for heart failure manage the symptoms, but not restore the loss cardiomyocytes due to the very limited regenerative capability in the adult heart. Novel reparative therapies that replace the cardiomyocytes loss are highly demanded to restore the cardiac function. The main purposes of this explanatory study is to investigate the safety and efficacy of the catheter-based endocardial delivery of human iPSC-derived cardiomyocytes in patients with congestive heart failure.

The EXCITE-HCM study is a randomized, controlled, blinded clinical trial designed to evaluate the effect of moderate intensity exercise training versus usual physicial activity on the improvement of HCM-related symptoms and cardiac function. About 70 participants will be recruited and randomized on a 1:1 ratio to either moderate intensity training or usual physicial activity interventions. Patients will be followed during a period of 24 weeks and assesesments as physical examination, questionnaires, 12 lead ecg's, biomarker levels, echocardiogram, Cardiac Magnetic resonance, PET and CPET will be performed to evaluate their response to the intervention.
