Optimized Biventricular Pacing Allograft Recipients
Dilated CardiomyopathyIschemic CardiomyopathyThis study tests optimization of biventricular pacing (BiVP) in patients with dilated cardiomyopathy (DCM) or ischemic cardiomyopathy (ICM) during cardiac transplantation in patients with advanced cardiac failure. It examines the effects of atrioventricular delay (AVD), interventricular delay (VVD or RLD), and left ventricular pacing site (LVPS) on cardiac output (CO). BiVP results are compared to traditional atrial (AAI) pacing at an identical heart rate.
Defining the Role of Insulin Resistance in 'Idiopathic' Dilated Cardiomyopathy
Dilated CardiomyopathyThis study will investigate the effects of rosiglitazone, a medicine commonly used to treat type 2 diabetes, on the utilization of glucose by the heart in patients with heart failure which is not due to heart attacks. The primary purpose of the study is to determine whether treatment with an insulin-sensitizing medication will improve the heart's ability to metabolize glucose (sugar).
The Effects of Ranolazine on CPET Parameters in Ischemic Cardiomyopathy Patients (ERIC)
CardiomyopathyThis is a proof of concept trial using ranolazine, a medication, in patients with known Coronary Artery Disease and reduced left ventricular function, EF < 40%. We propose that ranolazine therapy will result in demonstrative improvements in cardiac function that can be objectively assessed using the parameters measured with CPET. We propose that demonstrative improvement in CPET parameters on ranolazine will translate into improved patient outcomes for this patient population.
Incidence of Hypertrophic Cardiomyopathy in Infants of Diabetic Mothers Attending in NICU at Assiut...
Hypertrophic CardiomyopathyTo evaluate all full term infants of diabetic mother for the presence of hypertrophic cardiomyopathy who admitted in NICU at Assiut University Children Hospital and to follow up of these cases after 6 months for recovery.
An Exploratory Study of 18F-Labeled Hydroxyphenethylguanidines in Heart Failure Patients
CardiomyopathyThe main goal of this study is to test two new radioactive drugs, 4-[18F]fluoro-meta-hydroxyphenethylguanidine ([18F]4F-MHPG) and 3-[18F]fluoro-para-hydroxyphenethylguanidine ([18F]3F-PHPG) in human subjects with congestive heart failure. Evaluations of these imaging agents will include their uptake in heart, lungs and liver, their metabolic breakdown in blood, and their kinetics in the heart. Based on these studies, the better of the two drugs will be chosen for further studies in patients with heart disease. After the better compound is chosen, additional measures of its imaging properties, metabolism and pharmacokinetics will be done in subjects with heart failure.
Clinical Trial of Manganese-Enhanced MRI (MEMRI) to Assess Peri-Infarct Injury
ISCHEMIC CARDIOMYOPATHYThe purpose of this study is to evaluate the safety and tolerance of a new intravenous diagnostic agent, SeeMore or EVP 1001-1, in patients with Cardiovascular Disease (MEMRI scan). The initial phase of this study, NCT01989195 enrolling a total of 6 patients, has been closed. This second phase adds 10 patients in a safety cohort and 60 additional patients for a total of 70 patients.
Comparison of Ventricular Tachycardia Ablation Strategies in Patients With Ischemic Cardiomyopathy...
Ventricular TachycardiaThis is a prospective multicenter randomized open-label study aiming to assess whether endocardial or endocardial-epicardial ablation is superior to the standard approach (i.e., Antiarrhythmic drugs) in achievement of long-term ventricular tachycardia (VT) treatment success.
Ventricular Sling for Heart Failure With Reduced Ejection Fraction
Heart FailureCardiomyopathy1 moreThe purpose of this research is to investigate the effect of using this surgical technique in conjunction with bypass surgery to improve heart function and size, as well as decrease the possibility of future mitral valve surgery.
Danish ICD Study in Patients With Dilated Cardiomyopathy
Heart FailureDilated Cardiomyopathy1 moreThe primary objective of this study is to determine the efficacy of ICD therapy compared with control on the endpoint of death from any cause in patients with heart failure of non-ischemic oetiology.
Effects of Mitral Valve Repair With the Geoform Ring on Cardiomyopathy
Mitral Valve RegurgitationCongestive Heart Failure1 moreThe primary aim of this study is to assess the changes on the shape and function of the left ventricle in patients with severe mitral valve regurgitation due to congestive heart failure and cardiomyopathy who undergo mitral valve reconstruction with a Geoform ring. Three-dimensional echocardiogram will be used for precise evaluation of the shape and function of the ventricle.
