The Interrogation of the Cardiomyopathy of Chronic Kidney Disease With advancEd caRdiac Imaging...
Chronic Kidney DiseasesCardiomyopathies2 morePatients with kidney failure have a much higher risk of heart disease compared to people of the same age without kidney failure. The reason for this is not fully understood. In this project we will use Cardiac MRI (CMR), which is a very detailed scan of the heart and blood vessels, to try to better understand the cardiovascular changes that occur in kidney failure. We will perform CMR scans in 30 patients before and after dialysis (a treatment for patients with kidney failure) to see whether dialysis changes the heart muscle. The same patients will also undergo another type of heart scan, called a CT scan. This will allow us to compare the pictures from the 2 different types of scan to help us better understand any damage to the heart muscle that is present. Finally, we will test a new way to measure hardening of blood vessels on CMR. These three studies will help us to better understand the heart and blood vessel changes that happen in kidney failure. This research will also be useful for patients without kidney failure. We hope to be able to use it in the future to see which new treatments might be able to reduce the risk of heart disease in patients with kidney failure.
The Clinical Research of the Safety and Effectiveness Evaluation for Using Echocardiography-guided...
Hypertrophic Obstructive CardiomyopathyObjective to investigate the safety and effectiveness of Echocardiography-guided radiofrequency ablation in patients with Hypertrophic obstructive Cardiomyopathy (HOCM). Percutaneous intramyocardial septal radiofrequency ablation (Liwen Procedure) is a safe and effective treatment approach for Hypertrophic obstructive Cardiomyopathy and results in sustained improvement in exercise capacity, persistent in reducing Left Ventricle Outflow Tract (LVOT) gradient, and sustained improvement in cardiac function. In patients with disabling symptoms caused by Hypertrophic obstructive Cardiomyopathy (HOCM),Echocardiography-guided radiofrequency ablation could be a less invasive treatment option. Percutaneous intramyocardial septal radiofrequency ablation (Liwen Procedure) is a new method for the diagnosis or treatment of heart disease by using a special diagnosis and treatment device to the heart target area under the guidance of image technology. The method breaks through the worldwide problem of the minimally invasive diagnosis and treatment of the myocardium on the beating heart, so as to avoid the X-ray radiation and contrast agent damage . As a new pathway of cardiac disease intervention, Liwen Procedure can be used in congenital heart disease, myocardial biopsies, drug injection, cell implantation and instrument implantation in addition to Hypertrophic Cardiomyopathy and cardiac tumors. It has important clinical value and broad application prospect. In this study, Liwen RF radiofrequency ablation system was used to treat HOCM , and evaluate its safety and effectiveness , in order to provide a new medical device for Liwen Procedure of HOCM.
The Effects of SGLTi on Diabetic Cardiomyopathy
Type2 DiabetesHeart Failure With Reduced Ejection FractionDiabetic cardiomyopathy is associated with significant morbidity and mortality. It is considered as a cardiac muscle disorder secondary to diabetes mellitus (DM). Certain studies show the clinical benefit of SGLT-s inhibitors on reducing cardiovascular outcomes amongst patients with type II DM that go beyond the correction of hyperglycemic perse. Thus an observational imaging study is proposed to identify mechanistic insights of the drug group over cardiovascular events.
Early Administration of Ivabradine in Children With Heart Failure
Acute Heart FailureDilated CardiomyopathyThis is a monocentric, prospective, single arm, not for profit study. It is designed to study the early use of ivabradine in patients with dilated cardiomyopathy and Ejection Fraction (EF) < 45%.
Comparison of Squat-to-Stand Maneuver With Amyl Nitrite, Valsalva, and Exercise Stress Echocardiography...
Hypertrophic CardiomyopathyHypertrophic Obstructive Cardiomyopathy2 moreThe purpose of this study is to assess the effectiveness of squat-to-stand maneuver in eliciting left ventricular outflow gradients in patients with Hypertrophic Cardiomyopathy (HCM) compared to Valsalva, amyl nitrite inhalation, and exercise stress echocardiogram (ESE).
Validation of ERTugliflozin for Inhibiting Cardiac Fibrosis Using Cardiac MRI and Laboratory Parameters...
Heart Failure With Nonischemic CardiomyopathyBased on recent studies demonstrating SGLT2 inhibitors' favorable effects on cardiovascular outcomes especially for heart failure, the investigators hypothesize that sodium-glucose co-transporter-2 (SGLT2) inhibitor, ertugliflozin, is effective on reducing cardiac fibrosis in patients with nonischemic cardiomyopathy so the investigators try to examine this hypothesis in a single-center, double-blind, randomized controlled study using cardiac magnetic resonance (CMR). This study is a prospective, single-center, randomized, double-blind, two arm parallel group, placebo-controlled clinical trial involving patients with nonischemic cardiomyopathy. Patients meeting inclusion criteria without any exclusion criteria will be randomized 1:1 to ertugliflozin or placebo therapy, and cardiovascular functional assessment and clinical event follow-up will be undertaken.
Amiodarone Against ICD Therapy in Chagas Cardiomyopathy for Primary Prevention of Death
Chagas CardiomyopathyNon-sustained Ventricular Tachycardia1 moreThe primary objective is to compare the efficacy of the treatment using implantable cardioverter defibrillator (ICD) implantation to that of the treatment using amiodarone in the primary prevention of all-cause mortality in high-risk patients with Chagas cardiomyopathy and non-sustained ventricular tachycardia (NSVT).
Trimetazidine Therapy in Hypertrophic Cardiomyopathy
Hypertrophic CardiomyopathyHypertrophic cardiomyopathy (HCM) is a common inherited heart condition that causes breathlessness, chest pain and fatigue. There are few treatments available. The investigators have recently shown that a drug called perhexiline reduced symptoms and improved exercise capacity in patients with HCM. This change appears to be driven by alterations in myocardial energy metabolism. The aim of this trial is to test a similar drug, trimetazidine, in a group of symptomatic patients with non-obstructive HCM. HYPOTHESIS: trimetazidine will improve symptoms, peak oxygen consumption, cardiac function and arrhythmia burden in medically refractory symptomatic patients with non-obstructive HCM.
CZECH-ICIT (CZECH Inflammatory Cardiomyopathy Immunosuppression Trial)
Inflammatory CardiomyopathyThe aim of this study is to compare the effect of combined immunosuppressive therapy given on the top standard medical therapy of chronic heart failure according to current guidelines with standard medical therapy of chronic heart failure alone in patients with infammatory cardiomyopathy (ICM). Suitable subjects are characterized by EMB established presence of myocardial inflammation / negative polymerase chain reaction assay (PCR) findings of cardiotropic infectious agents and with varying duration of heart failure symptoms and left ventricular (LV) systolic dysfunction (phase A). Further, to compare the effect of two regimens of combined immunosuppressive therapy in these patients with ICM (phase B).
