Active clinical trials for "Cardiomyopathies"

We investigated whether treatment of central sleep apnea-hypopnea with bilevel positive airway pressure (BiPAP) in patients with idiopathic dilated cardiomyopathy (IDCM) would improve LV function.

Intracoronary infusion of bone marrow derived progenitor cells into the LAD in patients with non ischemic dilated cardiomyopathy.

This prospective study will evaluate in patients, fulfilling implant criteria for Cardiac Resynchronisation Therapy (CRT) implant, the optimal atrial contribution to the resynchronised ventricles in the event of right atrial pacing.

The human heart is divided into four chambers. One of the four chambers, the left ventricle, is the chamber mainly responsible for pumping blood out of the heart into the circulation. Diseases of the heart like congestive heart failure (CHF), can cause the left ventricle to function improperly. Medications called beta-blockers appear to reverse the abnormalities in the left ventricle and frequently improve the function of the left ventricle in patients with different kinds of heart disease. How beta-blockers improve left ventricle function is unknown. One possible reason for improved function of the left ventricle with beta-blockers is improved blood flow to the heart muscle. When a region of the heart is active, it uses more fuel in the form of oxygen and sugar (glucose). As heart activity increases, blood flow to and from the area of activity increases also. Knowing these facts, researchers can use radioactive sugar (glucose) and positron emission tomography (PET) scans to observe what areas of the heart are receiving more blood flow. In this study researchers plan to measure glucose use in heart muscle and blood flow to the heart muscle in patients with CHF taking beta-blockers.

The goal of this observational study is to learn about the occurrence of various arrhythmias ( tachyarrhythmia and bradyarrhythmia ) during or after Percutaneous Intramyocardial Septal Radiofrequency Ablation. The main questions it aims to answer are: To investigate the occurrence of various arrhythmias ( tachyarrhythmia and bradyarrhythmia ) during procedure and its relationship with clinical characteristics and procedural parameters To analyze the changes of 12-lead electrocardiogram and 24-hour dynamic electrocardiogram before and after Percutaneous Intramyocardial Septal Radiofrequency Ablation and their relationships with clinical characteristics and procedural parameters

The aim of the study is to analyze cardiac biomarkers, electrocardiograms and cardio-pulmonary exercise test (CPET) results in children with cardiomyopathies.

This is a retrospective cohort study of pediatric hypertrophic cardiomyopathy (HCM) patients using chart and registry review methodology. The studies objective is to develop and validate a sudden cardiac death (SCD) risk calculator that is age-appropriate for children with HCM that includes clinical and genetic factors.

The purpose of this study is to determine if LCZ696 is safe, tolerable and can improve exercise capacity (via improved peak VO2) in non-obstructive HCM patient population over the course of 50 weeks of treatment.

The purpose of this study is to determine if treatment with vitamin D3 of 10,000 International Units (IU) daily in vitamin D deficient patients for 6 months will improve B type natriuretic peptide (BNP), a marker of heart function, compared to placebo. The investigators also aim to determine if vitamin D helps cardiopulmonary function as evaluated by cardiopulmonary exercise test (CPX), laboratory values, strength, and quality of life in patients with stable congestive heart failure (Class II or III).

This is a multicenter, exploratory, randomized, double-blind study of the administration of mavacamten in 60 participants with symptomatic nHCM randomized to receive a 16-week course of mavacamten doses titrated to achieve 1 of 2 target drug concentrations.
