Active clinical trials for "Heart Failure"

In this pilot, investigator-initiated multi-centre, multinational, observational study the investigators would like to examine the impact of therapy optimization on the level of biomarkers in patients with acute decompensated and decompensated chronic heart failure. The primary objective is to determine the best time point for measuring biomarker levels during therapy optimization in patients with decompensation to predict clinical outcomes such as mortality, hospitalisation, and quality of life. Secondary objectives are: To evaluate the impact of guideline-recommended medication on biomarker levels during and following recompensation. To evaluate whether the trajectory of relevant biomarkers (MR-proANP, MR-proADM) is of relevance to guide medical therapy following decompensation. To evaluate whether the degree of biomarker change (e.g. slow versus rapid change) is of relevance with regard to hemodynamic stability and cardiovascular events such as hospitalisation. To evaluate whether the trajectory of relevant biomarkers (copeptin, CT-pro-ET1) is of relevance to guide medical therapy following decompensation.

The purpose of this study is to evaluate patterns of metabolic activity in the heart of patients with pulmonary arterial hypertension(PAH). Patients with PAH are at risk of developing weakness or failure of the right side of the heart.It is possible that there is a relationship between the development of heart failure and the way the heart uses energy sources, such as sugar. This study is designed to evaluate the way the heart uses sugar uptake in patients with PAH using positron emission tomography(PET imaging)

The number of patients with acute congestion on chronic heart failure is increasing. Ultrafiltration has recently been proposed as an alternative approach for the stabilization of volume balance, especially in patients with imminent diuretic resistance. There is increasing evidence that ultrafiltration may relief cardiac congestion with lesser effects on blood pressure and activation of renin angiotensin system, respectively . However, recent studies revealed conflicting results: demonstration the superiority of ultrafiltration in comparison to diuretic treatment, and a lack of evidence of benefit, as well as an excess of adverse events with ultrafiltration. Aquapheresis with adapted ultrafiltration rate guided by central venous pressure is safer than aquaphesis with a constant ultrafiltration with comparable effectiveness

Heart failure is the most costly diagnosis in the Medicare population. Clinical depression is strikingly common in heart failure patients, and not only diminishes their quality of life, but also is associated with a markedly increased risk of hospitalization or death. This study is designed to further our understanding of the behavioral and biological effects of depression in patients with heart failure, so that appropriate treatments can be developed.

The objective of this study is to confirm the safety and efficacy of the new Sentus OTW QP LV lead and Iperia ICD family. The study focuses on the safety and efficacy of the QP device system.

Study Purpose and Rationale The purpose of this study is to evaluate the lung Doppler signals changes during cardiac resynchronization procedure. As the LDS represent the various mechanical events of cardiac origin it is assumed that they may reflect the relative timing between contraction of the ventricles and atria and thus serve for effective synchronization of these activities. Aim of the study: The aim of the study is to assess whether the changes in Lung Doppler Signal (LDS) waves' characteristics will mimic the changes in echocardiographic parameters designed to assess diastolic inflow and systolic flow in patients undergoing Echo-based CRT optimization.

The aim of the study is I. To assess whether an individualized exercise training program is superior as compared to usual care with respect to exercise tolerance, II. to assess whether intervention tools that aim to increase exercise adherence are superior to an individualized exercise training alone with respect to exercise tolerance and long-term effects, and III. to identify biomarkers that that may be implemented into novel intervention tools aiming to increase exercise adherence in patients with chronic heart failure.

Prospective, follow-up registry of heart failure patients with or without sleep-disordered breathing (SDB). To test the hypothesis that treatment of nocturnal central sleep apnea with Cheyne-Stokes respiration by adaptive servoventilation (ASV) improves symptoms, cardiac performance and event-free survival.

Difficulty in breathing or increased rate of breathing are common causes of admission to intensive care unit. This may be due to heart failure, or other causes such as infection in the lungs. Treating doctors usually perform Chest X-ray, ECG, and other tests to know if breathlessness is due to heart failure or other cause. Doctors also give medicines to treat heart failure, or other conditions of the lungs based on the symptoms and investigation results. BNP is released by heart which is not functioning well. However BNP levels are also high in case of severe infection.Hence there is equipoise in utility of BNP measurements among critically ill patients, and it is not a current standard of care. The current cost of this test (about 1000 rupees per measurement) is high, and hence its utility needs to be carefully examined before a widespread use. The investigators intend to test the hypothesize that that on-admission BNP measurements, help clinicians identify CHF early, which may modify therapeutic decisions, and improve outcomes. The current study is designed with an objective to determine if on-admission BNP value and availability of its test results to treating physicians will reduce in-hospital, and 30-day mortality and in-hospital morbidity.

Based on the reversal of the adverse cardiovascular parameters during Laproscopic Surgery and its influence on cardiac activity in healthy subjects, the investigators expect to improved cardiac function in patients suffering from congestive heart failure.
