Filter by:The purpose of the present study is to evaluate the efficacy of the preconditioned autologous bone marrow mesenchymal stem cells for patients with ischemic heart diseases.
The purpose of this study is to investigate the safety and efficacy of intracoronary or intravenous infusion human umbilical Wharton's jelly-derived Mesenchymal Stem Cell (WJMSC) in patients with ischemic cardiomyopathy secondary to myocardial infarction.
Rationale: Nowadays ventricular tachycardia (VT) ablation in structural heart disease is performed primarily by early referral; while at the same time we still struggle with the limited longterm ablation success of endocardial VT ablation. An underestimated number of VTs from ischemic substrate have an epicardial exit. However, one cannot accurately predict who is in need of epicardial ablation. The investigators hypothesise endo/epicardial substrate homogenization in a first approach to be superior to endocardial substrate homogenization alone, in terms of recurrence on follow-up. Objective: To show superiority of a combined endo/epicardial approach compared to a stepwise approach in the ablation of ventricular tachycardia in a population with ischemic cardiomyopathy on VT recurrence. Study design: Multicenter prospective open randomized controlled trial. Study population: All patients above 18 years with an ischemic cardiomyopathy being referred for a ventricular tachycardia ablation. Intervention: One group undergoes endo/epicardial ablation and the other group has endocardial ablation only as a first approach. Main study parameters/endpoints: The main study endpoint is the difference in recurrences of ventricular tachycardia on follow-up - clinical or on implantable cardioverter defibrillator (ICD) interrogation - between the two ablation groups; secondary endpoints are procedure success and safety.
The aim of the present study is to investigate safety and efficacy of intramyocardial implantation of allogeneic mesenchymal stem cells in patients with ischemic cardiomyopathy .
There are some adults with skeletal muscle weakness (called "myopathy") and heart muscle weakness (called "cardiomyopathy") who have low blood levels of a compound called carnitine as a cause of their problems. Carnitine is very important to energy production in muscles. In fact, there are reports of some people with carnitine deficiency who have developed myopathy and cardiomyopathy that was completely reversed with carnitine treatment. The main objective of our project is to determine the number of patients who have carnitine deficiency as a cause of their myopathy and cardiomyopathy. The investigators will be measuring carnitine levels in 1000 patients with cardiomyopathy and will describe the specific features in all the study patients to see if there are any trends that may help us predict which patients with muscle weakness are at risk of developing low carnitine levels. The investigators will be treating patients with low carnitine levels with carnitine and observing them to see if their cardiomyopathy and their muscle weakness improve. Knowing the exact percentage of myopathy and cardiomyopathy patients with carnitine deficiency may allow for screening of patients in a cheap and targeted way to treat the serious complication of this condition, including heart failure and sudden death.
The purpose of the study is to perform endocardial catheter CRyo-Ablation to relieve the LVOT obstruction in patients with Hypertrophic Obstructive Cardiomyopathy. The investigators hypothesize that the investigators will be able to reduce > 50% of the initial LVOT gradient. This will be considered as a successful procedure.
The purpose of this study is to determine whether Salbutamol is effective in the treatment of severe heart failure due to ischemic and non- ischemic cardiomyopathy.
The purpose of this study is to develop and implement a critical pathway to identify patients with ischemic cardiomyopathy who are candidates for an implantable cardioverter-defibrillator (ICD). This study will also determine whether the use of the critical pathway for ICDs is associated with a change in the ICD referral and implantation rate.
The main aim of the study is to determine whether intramuscular injection of umbilical cord mesenchymal stem cells can improve the ventricular function of children with idiopathic dilated cardiomyopathy(IDCM); Secondary end-points will be: 1)To explore the possible mechanism of the improvement of ventricular function in children with IDCM and 2) to evaluate the safety of intramuscular injection of umbilical cord mesenchymal stem cell.
The purpose of this study is evaluation of expression of desmin in cardiomyocytes of patients with idiopathic dilated cardiomyopathy. Analysis of relationship between desmin expression and activities of mitochondrium and expression of ubiquitin.
