Active clinical trials for "Heart Failure"

The purpose of this study is to test the usefulness of measuring plasma brain natriuretic peptide (BNP) for diagnosis and prognosis in very elderly dyspneic patients.

Main goal of the study is the risk stratification of patients with advanced heart failure referred for orthotopic heart transplantation (OHT) according to HFSS score, other risk factors and biological markers and verification of their prognostic value in Polish population.

People with heart failure (HF) symptoms who are seen in the emergency department (ED) are often admitted to the hospital even though it may not be necessary. This study will gather information from HF patients seen in the ED to develop a decision-making tool that will help doctors predict the risk of HF-related death or serious complications. Improving the ability of ED doctors to effectively and safely manage low-risk HF patients should lead to fewer unnecessary hospitalizations.

The intent of this feasibility study is to collect and analyze intra-thoracic impedance measurements from a CRT-D device in a heart failure population.

To investigate the prevalence of vitamin D deficiency in patients with Heart Failure. To investigate if vitamin D levels are correlated to the degree of Heart Failure.

The purpose of this study is to determine if children with heart disease where there is only one pumping chamber("ventricle") have proteins (biomarkers") in the blood that can be used to monitor the function of their heart.

Patients often arrive to the Emergency Department with the chief complaint of shortness of breath. The cause of the shortness of breath may be due to many things, such as pneumonia, emphysema, a heart attack, heart failure, and others. It is often very difficult for the physician to determine the cause of the shortness of breath in the first two hours in the Emergency Department. This ambiguity makes treating the patient very difficult. Although a patient could benefit from treatment upon arrival, the emergent treatment of the condition must wait until a final diagnosis is made. Recently, emergency physicians have been using portable ultrasound at the patient's bedside to diagnose numerous conditions, including trauma, blood clots, kidney stones, etc. Recent research suggests that heart failure, one of the causes of shortness of breath, may be diagnosed within 5 minutes or less using ultrasound. Most of these studies come from the intensive care and cardiology. However, no research has yet been performed to determine if emergency physicians can effectively use ultrasound to quickly diagnose and treat heart failure within the first few minutes of a patient's arrival to the emergency department. The hypothesis of this study is to evaluate the ability of residents in emergency medicine to use ultrasound to diagnose patients in heart failure who presented with the chief complaint of shortness of breath. The final diagnosis of the patient upon discharge from the hospital will be compared to the preliminary diagnosis based on the portable ultrasound findings.

Lead survivability will be summarized.

The purposed of the study is to evaluate the pharmacokinetics (PK) response of continuous subcutaneous (SQ) infusion of cenderitide, as compared with a single SQ bolus.
