Active clinical trials for "Heart Failure"

Heart Failure (HF) is a significant healthcare concern in the US, with a 120% rise in mortality rates over 15 years costing the country an estimated $37.2 billion in 2009. Veterans are currently impacted at a rate of 5.2%, and cost an average of $14,959/individual/year for those utilizing the VA's Healthcare services. Research has shown that exercise training (ET) improves aerobic capacity, endothelial dysfunction, quality of life, and the ability to tolerate activity within the overall HF population. The purpose of this study is to examine the effects of structured exercise training and specific types of exercise training, walking, bicycling, and resistance training, on the symptom of fluid volume over load or edema in advanced heart failure patients.

This study will assess the safety, tolerability, and pharmacodynamics of omecamtiv mecarbil infusion in healthy male volunteers.

The purpose of this exploratory study is to assess the efficacy and safety of nesiritide in participants with acute (a quick and severe form of illness in its early stage) heart failure (when the heart inadequately pumps blood through the body) including acute exacerbation of chronic (lasting a long time) heart failure, administered intravenous (into a vein) bolus (a large amount) followed by intravenous infusion (a fluid or a medicine delivered into a vein by way of a needle).

A pilot study to examine the effects of LDL-Apheresis on patients with Stage III Congestive Heart Failure. Study hypothesis: Decreased blood viscosity from receiving LDL-apheresis will decrease workload on the heart and improve symptoms associated with the progression of Congestive Heart Failure

The purpose of this study was to assess whether Growth Hormone(GH)improves exercise capacity and cardiopulmonary performance in patients with chronic heart failure.

There is now strong evidence from clinical trials that carvedilol therapy in heart failure is superior to therapy with metoprolol. Not only does carvedilol have superior effects on lipid profiles, insulin sensitivity, renal blood flow, and reversal of pathologic remodeling but also its use is associated with fewer deaths compared to metoprolol. These facts make it important to carefully define how metoprolol and carvedilol are pharmacologically different. One potential difference is α1-AR antagonism. If we demonstrate that these α1-AR effects are preserved with chronic therapy, then α1-AR blockade may have an important role in carvedilol favorably altering the natural history of heart failure. On the other hand, if we demonstrate that tolerance to the α1-AR blockade effect of carvedilol decreases with time, then it would be unlikely that this pharmacologic property contributes to the efficacy of carvedilol. In such a case other pharmacologic properties, such as antioxidant activity, would appear to be important. These results will help guide future studies into CHF and AR blockade.

The purpose is to study if HF treatment guided by NTproBNP in addition to clinical symptoms and signs is more effective than treatment guided by clinical symptoms and signs alone in patients with HF and left ventricular systolic dysfunction

This 2 arm study will compare the safety, tolerability and efficacy of aleglitazar and Actos in patients with type 2 diabetes and symptomatic NYHA class II heart failure. Eligible patients will be randomized to receive either aleglitazar, titrated to an individual maximum tolerated dose up to 0.3mg p.o. daily, or Actos, titrated to an individual maximum tolerated dose up to 45mg p.o. daily, in addition to prescribed diabetes therapy where applicable. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

Will metformin improve exercise capacity in chronic heart failure patients who has insulin resistance (pre-diabetic- means before they become diabetic)?

The primary objective of this study is to establish the safety of CD-NP in normal human volunteers.
