NCT04325594
The purpose of this prospective single-arm clinical study was to evaluate the safety and potential efficacy of intracoronary administration of allogeneic umbilical cord-derived mesenchymal stromal cells (MSCs) as an addition to standard medical therapy in patients with chronic non-ischemic heart failure.

Cardiovascular disease is the leading cause of death worldwide. Advanced cardiovascular imaging using Magnetic Resonance Imaging (MRI) has proven to be effective in providing gold standard myocardial tissue characterization. Moreover, the intrinsic advantage of MRI's lack of exposure to ionizing radiation is particularly beneficial. At the same time, blood work can be very useful in early detection of certain cardiomyopathy, such as amyloid. However, there is a lack of agreement of on which markers are the most sensitive. This multi-study will allow us the unique opportunity to form a more comprehensive understanding for various cardiovascular diseases. Our team has developed novel cardiac MRI techniques that leverages endogenous tissue properties to reveal a milieu of deep tissue phenotypes including myocardial inflammation, fibrosis, metabolism, and microstructural defects. Among these phenotypes, myocardial microstructure has proven to be most sensitive to early myocardial tissue damage and is predictive of myocardial regeneration. In this study, the investigators aim to further study the importance of cardiac microstructure revealed by MRI in patient and healthy population and compare this novel technology with conventional clinical biomarkers.

Non-ischemic cardiomyopathies (NICM) represent a heterogeneous group of pathologies characterized by absence of obstructive disease of the epicardial coronary vessels and distinct structural and functional changes of the myocardium. The main identified forms include dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM), restrictive cardiomyopathy (RCM), and arrhythmogenic cardiomyopathy proper (ACM). More recently, further forms of cardiomyopathy have been described, less common and not uniquely classifiable, including: uncompressed myocardium (LVNC), peripartum cardiomyopathy (PPCM), structural correlates of arrhythmogenic mitral valve prolapse (AMVP), Anderson-Fabry disease (AFD), NICM associated with multi- system neuromuscular or autoimmune diseases, lysosomal diseases, glycogenosis, mitochondrial cytopathies and canal diseases with structural substrates. Finally, there are "overlap" forms, characterized by the sharing in the same subject of characteristic aspects of two or more of the above- mentioned diseases; and of the "undefined" forms, which to date do not reach the diagnostic criteria for any of the above-mentioned diseases. To the best of current knowledge, there are two points discovered in scientific research, namely the description of the arrhythmogenic and "inflammatory" phenotypes in a broad sense, which are summarized here with the acronym AINICM. In detail: 1. Arrhythmic manifestations account for the arrhythmogenic component of AINICM, which is not limited to ACM proper. In fact, most of the above diseases have a non-arrhythmic clinical presentation and a prevailing tendency to evolve towards a picture of cardiovascular decompensation. Although sudden arrhythmic death has been described throughout the spectrum of AINICM, early arrhythmic manifestations of such diseases have an unknown prevalence, an uncertain association with different disease genotypes and phenotypes, and still uncertain predictivity of long-term arrhythmic risk. At the same time, optimal diagnostic and therapeutic pathways in arrhythmias associated with AINICM are still being studied. 2. Myocardial inflammation (M-Infl) accounts for the inflammatory component of AINICM, and has recently been described in association with many AINICM on a genetic basis, including undefined and arrhythmic forms. The data is of high interest not only in the diagnostic, but also in prognostic and therapeutic field. In fact, on the one hand the presence of M-Infl seems to have a physio- pathological role in AINICM; on the other, as already known in myocarditis, the optimal therapeutic paths of arrhythmias may differ in patients with and without M-Infl; in particular, also in the light of the preliminary data available in adult and paediatric AINICM, the inflammatory forms are expected to respond better to immunosuppressive therapy, the arrhythmogenic ones to an ablative therapy with frequent need of implantation of cardiac devices. Based on the clinical presentation, NICM patients will be divided into arrhythmic (AINICM) and non-arrhythmic patients as study and control groups , respectively. The AINICM group will include presentation with ventricular fibrillation (VF), either sustained or non-sustained ventricular tachycardia (VT; NSVT), frequent premature ventricular complexes (PVC), supraventricular arrhythmias (SVA) and bradyarrhythmias (BA). Clinical presentations other than arrhythmic, including chest pain and heart failure, will define the control group. In parallel, as shown in Figure 1, patients with any evidence of M-Infl will be compared with those showing no signs of M-Infl.
NCT03830957
The aim of this study is to compare the effects of Ivabradine and metoprolol to reduce heart rate prior to coronary CT angiography in patients with advanced heart failure.
NCT01983293
The purpose of this study is to analyze the effect of left ventricular lead pacing location in the non-left bundle branch block (non-LBBB) heart failure patient population. The left ventricular lead pacing location will be guided by either the pacing site with the largest amount of dyssynchrony as measured by the LV electrical delay (QLV) or the physician's standard of care implant approach.
NCT02346422
The purpose of this trial is to characterize the safety profile and preliminary activity of high-dose MYDICAR® in persons with advanced heart failure when added to their maximal and optimized therapy.
NCT01058837
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.
