Filter by:The purpose of this study is to develop imaging protocols when using cardiovascular magnetic resonance (CMR) to assess cardiac functions, morphology and tissue characterization. The National Heart Research Institute Singapore (NHRIS) houses two dedicated CMR scanners to support the numerous investigator initiated projects in patients with various cardiac pathologists. By optimizing novel CMR sequences used in these studies, scanning time can be shortened for patients with underlying cardiac diseases.
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare condition in which the heart muscle cells especially of the main pumping chamber (the 'ventricle') is replaced by fat and scar tissue. Sarcoidosis is a condition that can affect many organs but when it affects the heart patches of inflammation can result in scarring, especially of the ventricles. Both conditions can cause dangerous heart rhythms and sudden death. Sarcoidosis can be treated with inflammation suppressing treatment (steroids), as well as pacemakers and implantable defibrillators which shock the heart back to normal rhythm. ARVC is usually treated with implantable defibrillators. The diagnosis of either condition can be difficult and indeed distinguishing the two can be extremely challenging. Increasingly nuclear scans (PET) are used to identify inflammation in the heart in patients suspected of having cardiac sarcoid. It is not known whether patients with ARVC have abnormal PET scans.
The aim of this randomized controlled study is to investigate the effect of continues positive airway pressure (CPAP) treatment in patients with dilated cardiomyopathy (DCM) and concomitant obstructive sleep apnea (OSA). The primary endpoint is left ventricular function measured by magnetic resonance (improvement of at least 4%) after six months treatment with CPAP. The secondary endpoints include diastolic dysfunction, cardiovascular biomarkers and quality of life.
Follow-up of a cohort of inflammatory cardiomyopathy patients (suspected or validated inflammatory cardiomyopathy) recruited at baseline by the SFB-TR19 project. Standardized protocols will be used for the assessment of medical history and examinations, laboratory biomarkers, and the collection of various biomaterials for biobanking purposes.
This randomized pilot phase I trial studies the side effects of donor bone marrow derived mesenchymal stem cells in controlling heart failure in patients with cardiomyopathy caused by anthracyclines. Donor bone marrow derived mesenchymal stem cells may help to control symptoms of heart failure and improve heart function.
Fibrosis, myocardial deformation and biomarkers in hypertrophic cardiomyopathy (HCM)
Dilated cardiomyopathy (DCM) causes significant morbidity and mortality and is the third most common cause of heart failure and the most frequent reason for heart transplantation. The etiology of dilated cardiomyopathy(DCM) is complex. There is a growing body of literature suggesting that the humoral immune system activation and autoantibodies against myocardial generation play an important role in the progression of DCM. At present immunoadsorption technology has been successfully applied in autoimmune antibody removal treatment of a variety of diseases. And some applications of immunoadsorption(IA) in patients with DCM showed that immunoadsorption(IA) can indeed reduce the autoantibodies, improve symptoms and prognosis, but additional research is needed to identify indications and instruments for the IA treatment of DCM.
Hypertrophic Obstructive Cardiomyopathy (HOCM) patients have significant clinical symptoms, including progressively increasing fatigue, angina, exertional dyspnea, and syncope. Conservative medications are used to treat the vast majority of patients. Invasive therapy, which includes surgical myectomy, septal ethanol ablation and dual-chamber pacing is introduced to patients with refractory symptoms or drug resistance. Considering the sternotomy and relatively high patients' tolerance required in myectomy, the potentially risky misplacement of ethanol and the anatomic variability of the vascularised hypertrophic septum, and the potential risk of conduction block after these two treatments, the development of new minimally invasive approach is warranted. Previous researches have illustrated the effectiveness and feasibility of transcatheter radio frequency ablation for HOCM patients. By far, there has been no report on transthoracic laser-induced interstitial thermotherapy (LITT) for human treatment. Since 2004, our department has adopted High Intensity Focused Ultrasound, radio frequency and laser in solid tumors treatment, including liver tumors and fibroid. Also our center has conducted several animal experiments to verify the feasibility of radio frequency/laser in septal myocardium ablation. The purpose of this study is to lead echocardiography-guided transthoracic radio frequency/laser ablation for HOCM ventricular septum, make minimally invasive treatment plans for HOCM patients, and verify the safety and validity of intervention treatment in long term.
The cardiac Fabry disease are early, frequent and severe, dominated by the frequency of left ventricular hypertrophy. They are responsible for a high morbidity and mortality, reducing life expectancy of 15 to 20 years for men. Fabry disease and heart attacks are still diagnosed late. This delay in diagnosis is due to the non-specificity of clinical, electrocardiographic and echocardiographic disease, but also by a certain ignorance of this pathology in the medical community. The importance of early diagnosis of Fabry disease and heart disease is well established: enzyme replacement therapy is most effective when instituted early, before the onset of irreversible damage such as fibrosis. With the blotter, we now have a simple and robust screening tool for Fabry disease, achievable consultation. Targeted educational interventions to physicians have shown their effectiveness in improving the screening and diagnosis of rare diseases. We offer a prospective observational type before / after study, which aims to assess the value of an educational brochure for cardiologists to improve the screening and diagnosis of Fabry disease in Normandy.
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.
