Filter by:This study aims to determine the effect of Coenzyme Q10 supplementation on conventional therapy of children with heart failure due to idiopathic dilated cardiomyopathy.
The objective of this study is to evaluate myocardial injury, if any, as quantified by cardiac markers (Troponin-T) in defibrillation threshold (DFT) testing during implantation of implantable cardioverter defibrillators (ICDs) using the upper limit of vulnerability (ULV) method vs. standard defibrillation threshold method.
If a surgical sponge is mistakenly left inside a patient's body after a surgical procedure, it can cause a serious infection. To prevent this from happening, a new device has been developed that uses radiofrequency (RF) signals to detect the presence of surgical sponges inside the body. The device is now being used routinely to make sure that no sponges are left inside a patient at the end of an operation. However, the RF device has not been implemented in procedures for patients with cardiac implantable electronic devices (CIEDs). While the device is FDA approved for use, there is a theoretical concern that the radiofrequency signals used to detect the sponges will change the settings on the pacemaker or the defibrillator. Changing the settings on a pacemaker might make it pace the heart too quickly or too slowly, while changing the settings on a defibrillator might cause unnecessary shocks or prevent it from shocking the heart if the patient were to have cardiac arrest. The purpose of this study is to test whether the radiofrequency device used to detect sponges can cause a clinically significant change to the settings on pacemakers and defibrillators. To minimize potential risk, the device will be tested only on patients who are having the pacemaker or defibrillator removed or replaced as part of their regular medical care, either because it is infected or because the battery has worn out. Before the pacemaker or defibrillator is removed, the settings will be carefully and completely recorded and the radiofrequency device will be used to scan the body for sponges as it would be done during normal operation. After the pacemaker or defibrillator is taken out, the settings will again be recorded and compared to the settings before the scan. In a standard device removal procedure, no clinically significant change in CIED settings would be expected. If a new pacemaker or defibrillator is implanted in the patient, it will not be exposed to the detection device at all. We will also test whether the RF device has any effect on temporary pacemakers that patients may receive after open heart surgery. We plan to perform testing in a total of 50 patients, 40 with permanent pacemakers or defibrillators and 10 with temporary pacemakers.
18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) may have application in a promising tool for identification of myocardial inflammation in patients with dilated cardiomyopathy (DCM).Therefore, the purpose of the study is to confirm the hypothesis of the fixation of FDG in non cardiomyocyte cells in a number of patients with DCM, to specify the frequency and describe the different binding profiles in comparison with MRI data. Patients will perform an ethologic evaluation of a non ischemic DCM with in a cardiac MRI. All patients will have with in 4 weeks after the MRI a 18F-fluorodeoxyglucose (FDG) PET. A high fat and low carbohydrate diet and an heparin injection will be prescribed to patients before this FDG PET. Patients will be identified as FDG+ or FDG -. The clinical status of the patient will be completed by a 12 months evaluation.
The "EUropean Comparative Effectiveness Research to assess the use of primary prophylacTic Implantable Cardioverter Defibrillators (EU-CERT-ICD)" is a modular research project to study the effectiveness of prophylactic ICDs in a prospective study, a retrospective registry, and meta-analyses of existing evidence on the subject.
The purpose of this study is to evaluate whether endocavitary intramyocardial injection of autologous bone-marrow-derived CD133+ cells is safe on the basis of number of adverse events, with follow-up assessments extending up to 1 year after enrolment.
To determine the effect of 12 weeks of chronic PDEV inhibition with Tadalafil versus placebo on basal cardiorenal and humoral function and on the integrated cardiorenal and humoral response to acute sodium loading in subjects with preclinical Diastolic dysfunction (PDD) and renal (kidney) dysfunction
This is a Phase 2 pilot study, involving a 48-week treatment period, designed to test the effectiveness of investigational study drug ARRY-371797 in treating patients with symptomatic genetic dilated cardiomyopathy due to a lamin A/C gene mutation, and to further evaluate the drug's safety. Approximately 12 patients from the US will be enrolled in this study.

This study sought to investigate the whether spironolactone protects the heart against anthracycline-induced cardiotoxicity.
