Active clinical trials for "Cardiomyopathies"

The purpose of this study to assess the longitudinal changes in left atrial strain and supraventricular arrhythmia burden after chemotherapeutic strategies in cardiac light chain amyloidosis.

To evaluate the effectiveness and safety of distal left radial (dLR) access in coronary procedures at a tertiary center in Trinidad and Tobago.

The main purpose of this study is to measure the amyloid burden, defined as extracellular volume (ECV) assessed by Magnetic Resonance Imaging (MRI) over time in a subset of up to 150 participants enrolled in ION-682884-CS2 (NCT04136171).

Liwen procedure is generally safe and effective in treating hypertrophic cardiomyopathy, but a small proportion of patients have complications after the operation. The goal of this observational study is to explore the incidence of postoperative complications of the Liwen procedure in hypertrophic cardiomyopathy patients underwent Liwen procedure in Xijing Hospital. The main question it aims to answer are: What is the incidence of complications in HCM patients underwent Liwen Procedure during postoperative hospitalization and a short-term follow-up period? What is the relevant factors of complications in HCM patients who underwent Liwen Procedure during postoperative hospitalization and short-term follow-up period? Can the complications of surgical patients during postoperative hospitalization be predicted? Participants have been evaluated using a variety of medical examinations before they underwent Liwen Procedure. Variants collected from medical examination and case history were used to analyze the association with each postoperative complication.

The aim of the study is to investigate safety and efficacy of intramyocardial implantation of allogeneic mesenchymal stem cells in patients with end-stage ischemic cardiomyopathy undergoing left ventricular assist device implantation.

Non-ischemic cardiomyopathy and heart failure are highly influenced by the presence of systemic inflammation. Doxycycline is a FDA-approved drug to treat bacterial infections which also shows powerful anti-inflammatory effects. In this study we plan to determine the effects of Doxycycline in patients with stable heart failure and non-ischemic cardiomyopathy on peak of aerobic exercise capacity (peak V02) and ventilator efficiency measured with a cardiopulmonary test.

The purpose of this study is to evaluate the effect of perhexiline on exercise performance (efficacy) and safety in patients with hypertrophic cardiomyopathy and moderate-to-severe heart failure following dosing for 16 weeks.

This blinded, controlled study will examine the impact of pomegranate polyphenol extract (POMx, from Pom Wonderful, LLC), 1000mg on cardiomyopathy in subjects with chronic renal insufficiency.

This is a randomized, prospective clinical trial comparing 2 different types of implantable cardioverter defibrillator (ICD) leads in children and patients with congenital heart disease. ICD lead survival in this patient group is particularly suboptimal, and lead extraction is technically difficult and carries a substantial morbidity risk. Recently, improved ICD lead designs have been released and are currently being utilized in patients. The main aim of the study is to determine if either type of lead performs better in terms of implantation electrical characteristics, long-term survival without breaking, and ease of extractability.

The purpose of the current study was to determine the factors associated with increased levels of anxiety and depression both before and after pacemaker implantation and examine if changes in these symptoms occur during the first postoperative year.
