Active clinical trials for "Heart Failure"

The purpose of this study is to determine whether endurance exercise of either high or moderate intensity can reverse structural and functional changes of the heart in patients with diastolic heart failure, and to investigate which type of exercise is best in terms of aerobe capacity and quality of life. The investigators expect that high intensity endurance exercise is superior to moderate intensity endurance exercise.

This study is being done to determine the effects of subcutaneous (under the skin) injection of human B-type natriuretic factor (BNP), Natrecor (nesiritide), a hormone produced by the heart, in combination with Tadalafil on: The pumping function of the heart Kidney function Hormonal function (levels of different hormones in your blood) in persons with lower pumping function of their heart.

The intent of this clinical study is to answer the questions: Is the proposed treatment safe Is treatment effective in improving the disease pathology of patients with Heart Disease as assessed by a series of measurements indicating improvement, stability, or degradation of a patient's cardiovascular function and exercise capacity?

Sympathetic system has important role occurrence of symptoms in heart failure. Renal denervation that is ablated some of sympathetic nerves is affected pathology of heart failure. This interventional therapy improves symptoms and life quality.

The purpose of this study is to define the safety of using bioimpedance for analysis of body composition in heart failure patients with ICD devices. The Biospace America InBody 520 scale, using direct segmental multifrequency bioimpedance, will be utilized to assess patients' fat mass, lean muscle mass, and edema status. Although the Biospace America InBody 520 scale is routinely used to analyze body composition in various settings including the Ahmanson-UCLA Cardiomyopathy clinic, due to theoretical concerns of safety, bioimpedance has not been routinely used in patients with ICDs. The investigators hope that this study will allow us to routinely analyze body composition in heart failure patients with ICDs, information which can be used to help guide dietary, exercise, and medical prescriptions for the investigators heart failure patients.

A multi-center, prospective, randomized, open-label blinded-endpoint trial in patients with heart failure will be conducted; 20 will be assigned to the standard dose vaccine dose and 20 patients to high dose influenza vaccine. Post-vaccine antibody measurements will be assessed, as well as tolerability differences between groups.

This is a pilot feasibility study to determine the effects of an activated vitamin D compound (paricalcitol) on heart structure (size) and function (ability to relax) in patients with normal kidney function and a form of heart failure known as HFPEF (heart failure and preserved ejection fraction). This study will also examine heart failure-related hospitalizations and changes in cardiac-stretch and biological markers that are believed to change along with heart size. Patients in this pilot study will be treated for a period of 48 weeks with paricalcitol at a dose previously approved by FDA (1 mcg per day) and followed-up for 4 weeks after treatment is completed.

To evaluate cardio-renal and overall safety profile of GE 145 320 mg I/ml Injection when compared to iopamidol 370 mg I/mL. The study will focus on elderly subjects with either chronic renal insufficiency, or diabetes mellitus (DM) requiring drug therapy, or congestive heart failure (CHF) NYHA Class III or greater, who are referred for a coronary catheterization procedure with or without PCI.

Sorin Group has developed a new atrial lead which is under evaluation during this study. The SonR atrial lead presents a new sensor in the tip of the lead and allows a new feature; interventricular (VV) and atrioventricular (AV) delay (VVD and AVD) optimization. The new RV autothreshold algorithm has been implemented in the CRT-ICD and will help the physician in his diagnosis avoiding potential lost of capture. The ICD device has also the capability to be remotely interrogated through the remote monitoring system whose performances will be reported during the study. Finally, the study will report the electrical and handling performances of the new left ventricular lead.

Patients treated with chemotherapy or immunosuppressives are at higher risk of influenza infection and mortality and morbidity are higher compared to healthy adults. Vaccination against the influenza virus can prevent these complications. In this study it is investigated whether vaccination during chemotherapy is effective in reaching protective serum antibody concentrations and the relation between time of vaccination (day 4 +/- 1 day versus day 16 +/- 1 day of the chemotherapy cycle).
