Different studies have shown that fibrosis of the heart increases the risk for a sudden death from e.g. arrhythmias. Magnetic Resonance Imaging (CMR) can easily identify even small areas o...
This study will collect MRI from healthy volunteer boys and boys with Duchenne Muscular Dystrophy (DMD) to help researchers identify and validate cardiac MRI biomarkers to better understan...
Due to the lack of information in the literature about the role of cardiac rehabilitation on Chagas heart failure, the aim of the present study was to evaluate the effects of a cardiac exe...
The CARE-HF trial evaluates the effects of Cardiac Resynchronization (CR) therapy on the mortality and morbidity of patients with heart failure due to left ventricular systolic dysfunction...
The purpose of this study is to compare contrast agents, Dotarem or MultiHance. The study will test to see how much of these two contrast agents are deposited in the bones or tissues of pe...
There has been an increasing interest in studying cardiac fibers in order to improve the current knowledge regarding the mechanical and physiological properties of the heart during heart failure (HF),...
The utility and role of cardiac magnetic resonance (CMR) as a non-invasive diagnostic imaging modality has been well recognized in the field of cardiovascular disease. Use of late gadolinium enhanceme...
Zinc is an essential cofactor for energy transfer and physiological heart function, has antioxidant properties, and is involved in multiple signaling pathways. We aimed to investigate the associations...
Patients with heart failure (HF) have increased levels of cardiac norepinephrine (NE) spillover, which is an independent predictor of mortality. We hypothesized that this increase in NE spillover in H...
The rapid growth in cardiac imaging utilization has led to the development of appropriate use criteria (AUC) in an effort to control costs. Recently, cardiac MRI has developed into a valuable modality...
Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE).
Tumors in any part of the heart. They include primary cardiac tumors and metastatic tumors to the heart. Their interference with normal cardiac functions can cause a wide variety of symptoms including HEART FAILURE; CARDIAC ARRHYTHMIAS; or EMBOLISM.
A state of elevated cardiac output due to conditions of either increased hemodynamic demand or reduced cardiac oxygen output. These conditions may include ANEMIA; ARTERIOVENOUS FISTULA; THYROTOXICOSIS; PREGNANCY; EXERCISE; FEVER; and ANOXIA. In time, compensatory changes of the heart can lead to pathological form of high cardiac output and eventual HEART FAILURE.
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
Compression of the heart by accumulated fluid (PERICARDIAL EFFUSION) or blood (HEMOPERICARDIUM) in the PERICARDIUM surrounding the heart. The affected cardiac functions and CARDIAC OUTPUT can range from minimal to total hemodynamic collapse.
