Filter by:Duchenne muscular dystrophy (DMD), the most common muscular dystrophy, leads to skeletal and cardiac muscle damage. Treatment of pulmonary complications has improved survival; however, heart muscle disease or cardiomyopathy has emerged as a leading cause of death, typically by the third decade. Although myocardial changes begin early, clinically significant heart disease is rarely detected in the first decade of life. Consequently, DMD cardiomyopathy frequently goes unrecognized (and untreated) until advanced (and irreversible). Current DMD cardiovascular care guidelines recommend beta-blockers and angiotensin converting enzyme inhibitors (ACEIs) when decreased ejection fraction (EF) is noted by echocardiography (echo); however, this strategy has not significantly improved outcomes. Our team has recently made a breakthrough in a mouse study, showing in a model that causes the same heart muscle disease in humans with DMD adding an old medicine traditionally used for high blood pressure and late-stage heart failure can actually prevent heart muscle damage. Because of this drug's proven safety in both children and adults, it is ready to be studied immediately in an RCT in patients with DMD to hopefully show, as we did in mice, that we can prevent the devastating consequences of heart muscle damage.
This is a case-control association study with multicentric prospective recruitment. Tako-TSUBO cardiomyopathy is a new clinical entity mimicking an acute coronary syndrome. It is characterized by reversible left ventricular dysfunction that is frequently precipitated by a stressful event and most of patients are postmenopausal women. Several hypotheses concerning pathogenesis of Tako-TSUBO cardiomyopathy have been proposed, but at present, exaggerated sympathetic stimulation is the main hypothesis. However, the investigators don't know why some patients with stressful event may present Tako-TSUBO cardiomyopathy whereas most of them don't. The investigators hypothesize that polymorphisms in the genes involved in the adrenergic pathway resulting in greater catecholamine sensitivity would be associated with an increased risk of Tako-TSUBO cardiomyopathy.
Exercise training (ET) is highly beneficial in heart failure patients and has been suggested to confer significant symptomatic and functional improvements in patients with diastolic dysfunction. Accordingly, the aim of this study was to examine the safety, feasibility of a structured ET program in symptomatic HCM patients.
This study will evaluate the relationship of markers of cardiac activation and their determinants. The hypothesis is that these markers will be interrelated.
The purpose of this study is to determine whether an autologous stem cell infusion through catheterism is safe and effective in the treatment of pediatric dilated cardiomyopathy. Process: 1. Primary Evaluation - Clinical History - Echocardiogram to evaluate ejection fraction and other parameters 2. Signing of Informed Consent and clearing doubts 3. Bone Marrow stimulation for 3 consecutive days with G-CSF (Granulocyte Colony Stimulating Factor) applied subcutaneously 4. On the 4th day, in operation room and under sedation: Bone Marrow Harvest performed by hematologists through posterior iliac crests(amount calculated at 8cc/kg, without exceeding 150ml). 5. Recovery room with family members while the cells are being processed in the Hematology Laboratory. 6. Approximately 3 hours after the 1st procedure, the patient re-enters the operation room, which is equipped for cardiac catheterization, so that cardiologists infuse the stem cells through the femoral artery into the coronary arteries which irrigate the heart´s muscle fibers. 7. Patient goes back to the recovery area until the anesthesia effect is gone and can tolerate oral liquids. 8. Clinical and echocardiographic follow-ups at 6 weeks and 6 months after the procedure.
A double blinded and placebo-controlled, dose escalation, single-center safety and preliminary efficacy study of cardiospheres delivered via NOGA MYOSTAR injection catheter in subjects with chronic ischemic cardiomyopathy. The objective is to achieve and document myocardial regeneration in patients with chronic scar.
Left ventricular non-compaction (LVNC) is a rare cardiomyopathy characterized by numerous excessively prominent left ventricular (LV) trabeculation and deep intertrabecular recesses communicating with the ventricular cavity and severely altering myocardial structure. Although most authors assume a developmental arrest in embryogenesis as the underlying pathology, the mechanisms of LVNC are not fully understood yet. Several gene mutations have been identified to be linked with LVNC and an autosomal dominant inheritance pattern is frequent To date the most commonly used imaging tool for diagnosing LVNC is echocardiography applying the criteria established by Jenni and coauthors However, qualitative parameters to differentiate normal compaction of the myocardium in healthy subjects from LVNC or from other cardiomyopathies like dilative cardiomyopathy (DCM) or hypertrophic cardiomyopathy (HCM) may fail due to highly variable LV trabeculation. Therefore, absolute quantification should be performed. Cardiac magnetic resonance (CMR) has been reported as a promising imaging modality to characterize patients with LVNC as it provides both a high spatial resolution and a good contrast between trabeculation and blood pool Jacquier et al. recently described a value of trabeculated LV myocardial mass above 20% of the global mass of the LV to be highly sensitive and specific for LVNC However, in their approach, a substantial degree of the LV cavity was included into calculated trabecular LV mass and led to systemic overestimation of the latter. Furthermore, the role and prognostic value of myocardial scarring as assessed by delayed enhancement (DE) CMR was not evaluated. The aim of the retrospective study was to establish revised and extended CMR criteria to distinguish LVNC from DCM, HCM and a group of healthy controls and to improve the assessment of trabeculated mass by excluding intertrabecular blood pool.
The purpose of this study is to evaluate the clinical safety and feasibility of Mysorba in patients with chronic non-ischemic dilated cardiomyopathy (DCM).
The purpose of this project is to conduct a preliminary test of the feasibility of a multi-micronutrient intervention to improve micronutrient status, cardiac function and quality of life in Veterans with Congestive Heart Failure (CHF).
Objective The objective of the study is to assess the structural and functional cardiac effects of treatment with losartan in patients with hypertrophic cardiomyopathy (HCM). Design The study is a randomized, placebo‐controlled, double‐blinded trial. The follow‐up period is 12 months. 130 patients with HCM will be included in predefined subgroups. Genotype positive relatives with borderline hypertrophy (> 13 mm) will also be included. Data on individuals with borderline hypertrophy will be analysed separately from the rest of the cohort. Primary outcome Ventricular hypertrophy assessed as left ventricular mass and maximal wall thickness.
