Active clinical trials for "Heart Failure"

Heart failure (HF) is a major public health problem, which affects about 5 million Americans.HF is when the heart muscle does not pump as much blood as the body needs. As a result of this,the body has difficulties in keeping an optimal fluid status. The fluid status of the body is regulated by both the heart and the kidneys. Due to the strong interaction between the heart and the kidneys, heart failure can result in a slight decreased kidney function as well. It is known that people who primarily suffer from chronic kidney disease (CKD) have a higher risk of developing arterial calcifications. Calcification of the arteries is caused by deposits of calcium within the walls of the blood vessels. Calcifications of the arteries may result in a loss of elasticity of the blood vessels. Recent research studies have shown that people with CKD have stiffer blood vessels which in these people, is associated with a higher chance of developing cardiovascular diseases. However, it is not known whether a decrease in kidney function in people with HF results in arterial calcification as well. In addition, it is not known whether this is also associated with a higher risk of developing cardiovascular diseases (diseases of the heart and blood vessels.) We are asking you to take part in this study because you have HF combined with some decrease in your kidney function. The purpose of this study is to see whether people with HF and a decrease in kidney function do have a higher chance of developing arterial calcifications. We will do this by comparing the results of the following; 1) several blood tests, 2) pictures taken of your heart by echocardiogram and computed tomography (CT) scan, and 3) measurements of the elasticity of your arteries. All of these tests are routinely used in clinical care. However, there have not been any research studies that have compared these results to see how they relate to arterial calcification in people with HF who have a decrease in kidney function. We also want to see whether people with HF and a decreased kidney function are at a higher risk of developing cardiovascular diseases. This study is being performed at Massachusetts General Hospital (MGH), in Boston Massachusetts. We expect to enroll a total of 150 subjects at MGH.

This was a non-interventional retrospective cohort study of de novo heart failure with reduced ejection fraction (HFrEF) patients (aged ≥18 years) commencing first-line treatment on either sacubitril/valsartan or commencing or continuing angiotensin-converting enzyme inhibitors (ACEi)/angiotensin receptor blocker (ARB) therapy for HF in the United States (US) using the secondary source of data, Optum Electronic Health Records (EHR).

Before a HF patient gets maximally decompensated and visit emergency department, most patients experience symptoms and signs of "on-going decompensation (or pre-decompensation)", which may not be noticed by the patients. If HF patients were aware of symptoms and signs of ADHF and received early intervention to stop the process of "on-going decompensation (or pre-decompensation)", it would be possible to reduce the rate of hospitalization for ADHF or death. Thus, self-awareness and self-examination of heart failure symptoms, signs and medical compliance using a patient diary in HF management may improve the outcomes in chronic stable HF patients. A patient diary with 6 parameters can serve this purpose: body weight, blood pressure, heart rate, drug compliance expressed as number of remaining pills of previous day, edema grade, and dyspnea grade.

Known before diagnosed heart failure and used diuretic therapy patients will be admitted in this study.The objective of this work is whether the Inferior Vena Cava Ultrasound can be used for management of Acute Heart failure therapy. And investigators will calculation correlation of extracted urine amount with Inferior Vena Cava diameter change. Researchers will not interfere to standard recommended treatment protocol, researchers will correlated the urine amount and changed vital signs with therapy with Vena cava inferior diameter.

Patients with heart failure NYHA >= II receiving non-emergent non-cardiac in-patient surgery will be randomized to receive either standard post-operative care (surgeon has to ask actively for specialist cardiological support) or a nurse-based heart failure management (nurses provide week-day support every day after surgery, if needed together with a heart failure doctor)

Study Details What is the study design? (eg, randomized, double-blind) Observational Prospective Study What are the overall objectives of the study? This project is designed to assess the feasibility of using a non-invasive hemodynamic monitoring device in heart failure outpatient clinics. There will be no alteration to patient management for this study. Rather this study seeks to assess the utility of the device by evaluating for the parameters obtained from the device to hospital admission. How your research will contribute to the advancement of scientific knowledge? ☒This study will confirm/strengthen existing knowledge. ☒This study will test a completely novel hypothesis. ☒This study will explore novel endpoints. ☐Other [please describe]:

Determination of hemodynamics plays an important role in the diagnosis of chronic heart failure. The gold standard is intermittent thermodilution via pulmonary artery catheter (PAC). Because of its invasiveness, there are certain risks of this method, e.g. injuries to the nerves and vessels, excessive bleedings, pneumothorax, cardiac arrhythmias etc. Noninvasive pulse contour Analysis (NPCA) is a new method which is able to determine hemodynamics noninvasively via a simple finger cuff. Advantages towards pulmonary artery Catheterization include a lower risk and an operator-Independent easy handling. Some studies investigated the accuracy, precision and trending abilities of noninvasive pulse contour analysis during anesthesia and in the intensive care unit, but there is no data available for its use in patients with chronic heart failure. The investigators therefore initiated this Trial to verify if NPCA is suitable for Determination of hemodynamics in patients with chronic heart failure.

The investigators aim to evaluate the utility of portal vein pulsatility as a predictor of the composite outcome of persistent organ dysfunction plus death in patients undergoing elective or urgent pulmonary endarterectomy for thromboembolic pulmonary hypertension. The investigators' hypothesis is that the portal vein pulsatility fraction, measured using transesophageal echocardiography immediately after weaning of cardiopulmonary bypass, is proportional to the risk of developing subsequent end-organ dysfunction in the postoperative setting.

The purpose of this study is to collect simultaneous surface electrocardiogram (ECG) recordings and Cardiac Resynchronization Therapy (CRT) intracardiac electrogram (IEGM) recordings of variations in electrical synchrony.
