Ischemic Heart Disease Clinical Trials

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.

This is a Phase IIA, randomized, double blind, placebo controlled, multicenter study designed to assess the safety, feasibility, and efficacy of umbilical cord derived mesenchymal stromal cells (UC MSCs), administered intravenously (IV) as a single dose or repeated doses, in patients with ischemic cardiomyopathy (ICM).

This study seeks to expand the use of the NYU GeriKit mobile application ("app") in a diverse range of settings to better phenotype older patients, which will enhance both research and patient care. Read Less

Among patients with stable ischemic heart disease who are referred for coronary angiography, a substantial proportion have non-obstructive coronary artery disease (CAD). Ischemia based on symptoms or stress testing may be due to coronary microvascular dysfunction in up to 40% of these patients. However, the mechanisms and optimal treatment of coronary microvascular dysfunction are unknown. Aberrant platelet activity and inflammation have been hypothesized as mechanisms of microvascular dysfunction. Investigators plan to evaluate association between platelet activity, inflammation, and coronary microvascular dysfunction in stable women referred for coronary angiography, and to identify non-invasive correlates of coronary microvascular dysfunction in these patients.

This study will be an observational registry to investigate the ability of magnetocardiography (MCG) in determining the presence of myocardial ischemia with the absence of obstructive coronary artery disease, by using an invasive reference standard coronary flow reserve (CFR) measured using thermodilution for diagnosis. Up to 200 participants in a 1:1 ratio of CMD positive to CMD negative will be enrolled. The device is a magnetocardiography (MCG) scanner named CardioFlux, which is paired with cloud processing software. A CardioFlux scan appointment shall last approximately 15 minutes in duration and include a patient questionnaire following the scan. Read Less

The purpose of this study is to test the hypothesis that allogeneic Mesenchymal Stem Cells (MSCs) promote systemic and coronary endothelial repair through rescue of bone marrow progenitors in type 2 diabetic patients with symptomatic IHD compared to placebo. Read Less

Heart failure (HF) is an enormous health burden affecting approximately 5.1 million people in the US and is the cause of 250,000 deaths each year. Approximately 50% of HF is caused by myocardial ischemia and requires immediate restoration of coronary blood flow to the affected myocardium. However, the success of reperfusion is partly limited by intramyocardial hemorrhage, which is the deposition of intravascular material into the myocardium. Hemorrhagic reperfusion injury has high prevalence and patients have a much greater risk of adverse left ventricular remodeling, risk of fatal arrhythmia, impaired systolic function and are hospitalized at a greater rate. Recent magnetic resonance imaging techniques have improved assessment of reperfusion injury, however, the association between MRI contrasts and reperfusion injury is highly unclear, and lacks specificity to IMH. Improved imaging of IMH and accurate knowledge about its spatial and temporal evolution may be essential for delivery of optimal medical therapy in patients and critical to identify patients most at risk for adverse ventricular remodeling. The overall goal is to investigate the magnetic properties of hemorrhage and develop MRI techniques with improved specificity to hemorrhage. New MRI techniques permit noninvasive assessment of the magnetic susceptibility of tissues and can target tissue iron. Therefore, the investigators hypothesize that MRI imaging of myocardial magnetic susceptibility can map hemorrhagic myocardium. The investigators will perform a longitudinal observational study in patients after reperfusion injury to validate these methods, compare the methods with conventional MR contrasts and develop MR methods for imaging humans.
