Active clinical trials for "Heart Failure"

The purpose of this study is to explore manifestations of Heart Failure Using Infrared Thermal Imaging Technology.

Study hypotheses is that in patients with heart failure and atrial fibrillation, reduced left atrial appendage (LAA) emptying velocities leads to LAA thrombus formation therefore a higher rate of stroke and embolism are observed even on oral anticoagulants. Therefore The left atrial appendage closure (LAAC) procedure's benefit in patients with an impaired left ventricular ejection fraction (LVEF) has to be investigated So the study is to assess the safety and prognosis of left atrial appendage closure (LAAC) in patients with heart failure in preventing thromboembolic events, bleeding and all-cause mortality. Patients will be divided into to groups, one group includes patients with no evidence of heart failure, and another group including patients with previous history of or with an evidence of with heart failure.

To provide new ideas for the treatment of patients with ischemic heart failure, this study is to search for differential metabolic markers associated with ischemic heart failure and to study the influence of fecal flora on the course of heart failure in patients with ischemic heart failure.

An open label,single-center, non-interventional prospective study with the aim on investigating the effect of intravenous ferric carboxymaltose in restoring iron status and reducing the risk of severe arrhythmic events in participants with iron deficiency and a reduced ejection fraction (HFrEF).

The purpose of this study is to evaluate prospectively the safety and performance of the MOBYBOX System in the veno-arterial configuration in patients with cardiorespiratory failure or in the veno-venous configuration in patients with severe respiratory failure.

The purpose of this study is to develop and implement a critical pathway to identify patients with ischemic cardiomyopathy who are candidates for an implantable cardioverter-defibrillator (ICD). This study will also determine whether the use of the critical pathway for ICDs is associated with a change in the ICD referral and implantation rate.

The diagnosis of asymptomatic left ventricular dysfunction is difficult in general practice since it requires transthoracic cardiac echocardiography that is generally performed in specialized services. Although blood BNP levels monitoring can be of some help in heart failure diagnosis is is mostly a late biomarker that is secreted upon heart stretch and has many limitations. Therefore the aim of this study is to identify new specific blood biomarkers that would help for asymptomatic left ventricular dysfunction diagnosis in large populations with cardiovascular risk.

Several large trials have shown that beta-blocker treatment reduces the risk of death and hospital admission in patients with symptomatic heart failure. Unfortunately, survey data suggests relatively poor utilisation of beta-blockers, despite ample evidence for good tolerability. Additionally there are several important unanswered questions, such as clinical efficacy for specific sub-populations (women, the elderly and patients with diabetes or other co-morbidities) and the effect of beta-blockers in combination with other medications. Previous meta-analyses, based on published tabular data, have been conducted although this approach has important biases and limitations. We plan to perform a carefully conducted systematic review of individual patient data from the major randomised trials of beta-blockers in heart failure. The goals of this collaborative project are to clarify the overall efficacy of beta-blockers and identify sub-groups that show particular benefit, thereby increasing the use of beta-blockers, reducing adverse clinical outcomes and the high costs associated with this condition.

The purpose of the study is to determine whether the excretion of renal water- and salt-channels in the urine reflects the handling of water and salt in the kidneys, and whether the excretion can be used to monitor and/or predict the effects of treatment of certain heart or lung diseases.

Obesity sarcopenia, characterized by the coexistence of excess fat and muscle mass reduction, may contribute to the pathophysiology of exercise intolerance in patients with heart failure with preserved ejection fraction (HFpEF). The project will examine the impact of selected circulating miRNAs on processes that may form the pathophysiological basis for HFpEF development and obesity sarcopenia in correlation with biochemical markers, echocardiographic assessment and non-invasive assessment of hemodynamic parameters. In addition, the impact of LDL and HDL on these diseases will be assessed. Determinations of selected adipokines and asymmetric dimethylarginine will also be carried out and their effects on the cardiovascular system will be assessed.
