Active clinical trials for "Heart Failure"

This study was designed as a randomized, double blinded and placebo-controlled clinical trial. The aim of the study is to evaluate the efficacy and safety of Zhigancao Tang granule in patients with HFpEF of Qi-Yin dificiency.

The main purpose of this research is to reveal the curative effect mechanism of Yiqihuoxue prescription which treat the disease of qi deficiency and blood stasis. And at the same time this study also try to confirm yiqi huoxue fang qi deficiency blood stasis treatment of coronary heart disease (CHD) heart failure the curative effect and security.

One third of patients diagnosed with heart failure demonstrate left ventricular reverse remodelling and recovery of cardiac function following a period of medical therapy. These patients have an excellent long-term prognosis. Whether they need to remain on long-term medical therapy is not clear. The investigators will investigate the safety of therapy withdrawal in patients with a previous diagnosis of heart failure and recovered cardiac function, in a randomised controlled trial.

Heart failure is an incapacity to provide adequate blood flow to the others organs, such as brain, liver and kidney. The patients presents weakness and fatigue of inspiratory muscles, mainly diaphragm muscle, that contributes to dyspnoea and limited physical capacity in this patients. Some methods are being studied to decrease the diaphragm weakness. The diaphragm functional eletrical stimulation is a new technique, which has been studied to improve the respiratory muscle strength. Then, the aim of this study is to assess the effects of diaphragm functional electrical stimulation (FES) on respiratory muscle strength and muscle architecture of patients with heart failure. For this the following assessments will be performed before and after stimulation: manovacuometry to verify the maximum inspiratory pressure and maximum expiratory pressure; and ultrasonography to assess muscle architecture. The subjects will be selected by the decompensation in heart failure, with the adequate elegibility criteria. This study have no control group, because this technique has been little researched and could be unethical with the patient who won't receive this treatment. The subjetcs of this research will receive the diaphragm functional electrical stimulation twice of day for consecutive five days or until the hospital discharge. Expected results at the end of the protocol with Diaphragm Functional Electrical Stimulation are: to improve respiratory muscle strength; to correlate with diaphragm muscle arquiteture.

This trial will assess the efficacy and safety of QSG in CHF.

100 pt multicentre study 50 pts randomised to triventricular pacemaker, 50 to biventricular pacemaker Feasibility study with 6 month outcome data

We aim to determine the effectiveness of lung impedance guided preemptive therapy (LI-Guided) of chronic heart failure patients with preserved ejection fraction (LVEF ≥ 45%) who are being treated in our hospital's outpatient clinic.

The purpose of this study is to determine whether inspiratory muscle training is effective to improve breathless and exercise intolerance in symptomatic patients with chronic obstructive pulmonary disease (COPD) plus chronic heart failure (HF).

The apelin-APJ system is a recently discover hormone system that has several important actions in the cardiovascular system. Apelin causes the heart pump with more force and also causes blood vessels to relax. Studies to date show that people with reduced pumping function of the heart have lower levels of apelin in the bloodstream compared to people with normal heart function. We have previously given apelin to healthy volunteers and people with reduced pumping function and this increases the heart's contraction. However, this has only been assessed over a short time period, around fifteen minutes, and we now want to know if this effect is seen over a longer period.

Several studies have shown that inflammation and matrix degradation have pathogenic effects on the myocardium by influencing heart contractility, inducing hypertrophy, degrading the matrix, or enhancing fibrosis, thus contributing to the continuous myocardial remodeling process. The sedative and antinausea drug thalidomide has been shown to have both anti-inflammatory and antioncogenic properties that could be of benefit in case of congestive heart failure (CHF). Previous, small investigations have shown an improvement in left ventricular ejection fraction and a favorable cardiac remodeling during thalidomide therapy.
