Filter by:To demonstrate that after 12 weeks of open-label lixivaptan treatment, serum sodium is maintained in hyponatremic patients continuing to receive lixivaptan compared to placebo during the 4 week double blind treatment period.
The purpose of this study is to determine whether melatonin can improve sleep, quality of life and markers of heart failure in patients with heart failure.
This study explores a potential drug-drug interaction between istaroxime and digoxin in patients with stable CHF on chronic oral digoxin treatment.
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.
The purpose of this study is to assess the safety and efficacy of istaroxime in patients hospitalized for Acute Decompensated Heart Failure (ADHF) not requiring inotropic therapy.This will be done by comparing the hemodynamic effect of a 24-hour infusion of three different doses of the drug versus placebo. Efficacy will be measured as a change in Pulmonary Capillary Wedge Pressure from pre-infusion to 6 hours after infusion start. Secondary objectives will include the evaluation of clinical efficacy and safety through assessment of cardiovascular and renal tolerability as well as changes in biological markers such as brain natriuretic peptide (BNP) and troponin I (TNI), and the neurohormones renin and aldosterone and also to assess the pharmacokinetics of istaroxime and its metabolites.
Secondary hyperaldosteronism and the non-osmotic release of arginine vasopressin (AVP) are the major factors in sodium and water retention in pulmonary arterial hypertension with right ventricular failure. Natriuretic doses of mineralocorticoid antagonist and aquaretic doses of V2 receptor antagonist will attenuate the sodium and water retention respectively, and be associated with clinical improvement.
Heart Failure is a growing and challenging public health concern in the United States. Heart failure commonly manifests as a syndrome of salt and water retention. Arginine vasopressin is a peptide hormone that is intimately involved in salt and water homeostasis. AVP is released into the circulation in response low blood volume and hypernatraemia. Despite fluid overload, vasopressin levels are often inappropriately elevated in patients with heart failure and LV dysfunction. Data suggest that vasopressin may also contribute to the deleterious circulatory response in patients with heart failure and play a role in the development and progression of the disease process. In their study, Udelson et al. showed that vasopressin receptor antagonism with Conivaptan resulted in significant diuresis with stable hemodynamics in advanced heart failure patients. Currently Intravenous diuretics and vasodilators are the standard of care in treating patients with acute decompensated heart failure. We will be studying the renal and diuretic effects of add on therapy with intravenous Conivaptan in patients receiving intravenous Nesiritide and intravenous diuretics.
The investigators aim to examine how medical conditions that indicate high cardiometabolic risk, such as increased body weight, high cholesterol levels and high blood pressure, affect heart structure and function among individuals with known HF. Furthermore, this study is being undertaken to identify potential differences in these effects between non-Hispanics whites and Mexican Americans.
The purpose of the study is to evaluate whether sildenafil helps treat heart failure. Some patients with heart failure have high blood pressure in the lungs (referred to as "pulmonary hypertension"). Sildenafil is a medication that is used to treat high blood pressure in the lungs and may reduce symptoms of heart failure. Studies have looked at the short-term benefit of sildenafil in patients with congestive heart failure, but this study will look at the longer-term benefits of 12 weeks of therapy with sildenafil.
Nottingham Primary Care Trust has launched telemonitoring to support: independent living and self-management ability of people with congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD) and co-morbidities; and reduce the health care utilisation associated with these patients, including the number of hospitalisations, GP visits and community matron and specialist community nurse home visits. The Multidisciplinary Assessment of Technology Centre for Healthcare (MATCH) will evaluate the technology and its impact of this telemonitoring system on quality of care (i.e. process measures), patient outcomes and direct healthcare costs from an NHS perspective.
