Filter by:The investigators propose a pilot randomized controlled trial to determine the safety and potential benefits of moderate intensity exercise in patients with hypertrophic cardiomyopathy. The investigators hypotheses are that exercise parameters derived from a baseline cardiopulmonary exercise test will target an appropriately safe level of exercise intensity that will not cause significant arrhythmias or exacerbate symptoms and that exercise training for 4 months will result in significant improvements in peak oxygen consumption (peak VO2) and quality of life, with neutral effects on the clinical characteristics.
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.
Hypertrophic cardiomyopathy (Hypertrophic CardioMyopathy=HCM) remains a poorly understood disease with an assumption insufficiently codified. There is no data available in France on the profile of patients, diagnostic methods and assessment and therapeutic use. The purpose of this study is to establish a monitoring of patients with HCM (sarcomere of origin or not) in France (diagnosis, treatment)
We would like to investigate novel diagnostic methods or biomarkers to early predict the success of ECMO therapy for cardiogenic shock patients during the early stage after ECMO treatment.
Peri-partum cardiomyopathy is a heart muscle weakness that occurs during or following pregnancy. Research suggests that many initial heart injuries including viruses, pregnancy and other unknown causes, can lead to a process of inflammation of the heart muscle which can weaken the heart and cause cardiomyopathy. Why this process occurs in women during pregnancy is not well understood and if it differs from those women who develop cardiomyopathy from a virus is unknown. This study has been proposed to look at genetic information (DNA) as well as the immune system (the body's response to fight off infections and/or viruses) to find possible causes for the heart muscle damage that occurs in peripartum cardiomyopathy.
Biventricular Pacing has been shown an improvement of symptoms in patients with heart failure. A temporary pacing is necessary in patients after cardiac procedures. In patients with hypertrophic cardiomyopathy, a single right ventricular pacing can decrease the cardiac output and blood pressure. The investigators propose that biventricular pacing in these patients and conditions results in an improvement of symptoms instead of single right pacing.
Sudden cardiac death (SCD) poses a significant health care challenge with high annual incidence and low survival rates. Implantable cardioverter defibrillators (ICDs) prevent SCD in patients with poor heart function. However, the critical survival benefit afforded by the devices is accompanied by short and long-term complications and a high economic burden. Moreover, in using current practice guidelines of reduced heart function, specifically left ventricular ejection fraction (LVEF)≤35%, as the main determining factor for patient selection, only a minority of patients actually benefit from ICD therapy (<25% in 5 years). There is an essential need for more robust diagnostic approaches to SCD risk stratification. This project examines the hypothesis that structural abnormalities of the heart itself, above and beyond global LV dysfunction, are important predictors of SCD risk since they indicate the presence of the abnormal tissue substrate required for the abnormal electrical circuits and heart rhythms that actually lead to SCD. Information about the heart's structure will be obtained from cardiac magnetic resonance imaging and used in combination with a number of other clinical risk factors to see if certain characteristics can better predict patients at risk for SCD.
This application proposes a prospective, single arm feasibility clinical trial of a 12-week period of combined endurance and resistance training in survivors of childhood cancer who were treated with doxorubicin and/or daunorubicin and have impaired cardiac function. Baseline and post intervention imaging, laboratory, and neuropsychological evaluations will be used to determine the effects of the intervention on body composition, serum lipid profile, exercise tolerance, and neurocognitive functioning. Participants will be called weekly to monitor compliance with the intervention. Incentives will be given at intervals during the trial to optimize compliance with the intervention.
The overall purpose of this study is to evaluate the effect of gastric bypass surgery-induced weight loss on the heart's function and on fat deposits in the heart muscle.
No clinical trial that has examined the role of implantable cardioverter defibrillator (ICD) therapy in the prevention of Sudden Cardiac Death (SCD) has provided outcome data for longer than a few years. The NHLBI sponsored and placebo-controlled Sudden Cardiac Death in heart Failure Trial (SCD-HeFT) conducted from 1997 to 2003 had the largest number of patients and the longest average follow-up at 45.5 months. This study changed the national reimbursement policy for ICD therapy and remains the reference point for all other ICD evaluations in patients with congestive heart failure from ischemic or non-ischemic systolic dysfunction. Despite the outcome, the role of ICD therapy in the management of patients with heart failure has been questioned because of four principal concerns: numbers needed to treat to save a life, lead integrity over time, the negative consequences of shock therapy, and the cost of therapy. The purpose of this trial is to track down the remaining patients for a one-time follow-up regarding key outcome data.
