Filter by:The study focuses on the development of a new personalized approach to diagnostics and surgical treatment of patients with ischemic cardiomyopathy. The algorithm for selection of patients for certain type of cardiac surgery will be developed. The models for prediction of the risks and outcomes of cardiac surgery will be elaborated to reduce the rate of complications in the early and long-term postoperative period in patients with ischemic cardiomyopathy. Imaging modalities, methods for assessement of structural and functional state of the myocardium, biochemistry testing, immunohistochemical examination, and myocardial biopsy studies will be used to achieve these goals.
The purpose of this study is to evaluate the safety and effectiveness of an experimental drug called human allogeneic mesenchymal stem cell therapy.
The purpose of this research is to investigate the effect of using this surgical technique in conjunction with bypass surgery to improve heart function and size, as well as decrease the possibility of future mitral valve surgery.
Objective of the study: to evaluate whether edge-to-edge technique improves clinical and hemodynamic results in patients scheduled to septal myectomy for severely symptomatic hypertrophic obstructive cardiomyopathy.
All patients with heart disease should have the opportunity to participate in research into their condition, to advance knowledge and treatment. The HeartHive COVID-19 study is an international online pilot observational cohort study evaluating the impact and clinical outcomes of the COVID-19 pandemic on subjects enrolled in the HeartHive. Cardiomyopathies are progressive diseases, and there is a need to better understand what factors affect the chances of developing cardiomyopathy, and how the condition progresses. The impact of the COVID-19 pandemic on patients with cardiomyopathy has not been explored and represents a critical unmet need. Insights into exposure, healthcare outcomes, behavioural changes and the psychosocial ramifications of the pandemic are required to better understand the health needs of this population during these unprecedented circumstances and to adapt clinical services to meet these. The study will entail completing serial online surveys during the pandemic. This study uses The Heart Hive - an international, online registry of patients with self-reported clinically diagnosed cardiomyopathy, and people without heart disease. Participants enrol and upload their own data through the website. It is the second research study that will be offered to registry participants and delivered through The Heart Hive platform.
Cardiomyopathy is a condition that affects the heart muscle, whereby it becomes enlarged, thick or rigid. When the heart muscle becomes involved, it affects the pumping action of the heart. This condition can affect as many as 10% of all patients after undergoing anthracycline cancer drug therapy and unfortunately carries the worst prognosis of all cardiomyopathies. To date, there is no effective intervention that will prevent a patient from developing this condition. The research conducted will look to see if an energy imbalance in the heart predates the onset of detrimental changes to the pumping function of the heart, if this is detected then we can act earlier to prevent the pumping function deteriorating.
This study aims to identify and assess new CMR techniques that can improve current CMR protocols.
using a contrast-enhanced (CE) cardiac magnetic resonance imaging(CMR) which included the measurement of T1 mapping, T2 mapping, T2* mapping and late gadolinium enhancement(LGE) sequences, as well as LVEF and extracellular volume(ECV) to evaluate the respective changes before and after anthracycline chemotherapy.
Hypertrophic cardiomyopathy (HCM) is a frequent cardiac pathology with an estimated prevalence of 1/500 in France. The main risk factor for sudden death in this pathology is the presence and extent of left ventricular obstruction. To date, the only method allowing a reliable assessment of the extent of left ventricular obstruction is Doppler echocardiography. All patients with HCM should undergo cardiac magnetic resonance imaging (MRI) to confirm the diagnosis and for the detection of fibrosis, but conventional sequences cannot reliably assess the obstruction. 4D-flow MRI provides a complete coverage of an entire volume with the ability to simultaneously measure the outputs of all vessels within that volume in a single sequence and might be able to quantify left ventricular obstruction. The main objective of this study is to compare the quantification of left ventricular obstruction in hypertrophic cardiomyopathy by Doppler echocardiography and 4D flow MRI.
Hypertrophic Cardiomyopathy (HCM) is the most common inherited heart muscle condition affecting up to 1 in 200 of the general population. It results from mutations in genes encoding components of the contractile apparatus in the heart muscle cell (myocyte). These mutations result in increased energy cost of force production for the myocyte which then cumulatively causes a myocardial energy deficit. This myocardial energy deficit is then thought to lead to cardiac hypertrophy ('left ventricular hypertrophy' or LVH) in HCM. LVH leads to impairments in heart muscle function, heart muscle oxygenation and microvascular blood flow and is the chief driver of patient symptoms in HCM. These symptoms consist of chest pain, shortness of breath, dizziness, fainting episodes or palpitations. Occasionally, the disease may cause sudden cardiac death (SCD). HCM is the most common cause of SCD in young people including competitive athletes. In addition, HCM has been found to result in significant global deterioration in health-related quality of life. Treatment of HCM has focused on relief of symptoms by drugs such as ß-blockers which slow the heart rate and improve heart function. However, symptom relief is often incomplete and there is no evidence on the benefit of ß-blockers or related medications to reverse LVH. Perhexiline, a potent carnitine palmitoyl transferase-1 (CPT-1) inhibitor shifts myocardial metabolism to more efficient glucose utilisation and rectifies impaired myocardial energetics. It is currently used to treat angina in patients with coronary artery disease. There is some preliminary evidence that Perhexiline may aid in the improvement of symptoms in patients with HCM. However, the effect of any form of therapy on potential regression of LVH in HCM remains unexplored. In this randomised double-blind placebo-controlled trial, the investigators will use state of the art cardiac imaging, principally advanced echocardiography and Cardiovascular Magnetic Resonance (CMR) to study the effects of perhexiline on LVH, cardiac function, and oxygenation in symptomatic patients with HCM. The investigators hypothesize that perhexiline will favourably reduce LVH and improve myocardial oxygenation by improving myocardial energetics, and that these putative morphological and functional changes can be accurately measured utilizing echocardiography and CMR. If this pilot study supports the hypothesis, then it will pave the way for a major randomised controlled trial to definitely determine the role of Perhexiline in HCM.
