Active clinical trials for "Heart Failure"

The aim of the study is to determine the analytical characteristics of the microRNA enzymatic immunoassay (miREIA) method and to determine various relations among miRNA biomarkers and heart failure (HF) with reduced ejection fraction(HFrEF). The investigators assume that there are correlations between levels of selected miRNA and HFrEF. These correlations provide information to formulate pathophysiological conclusions, which will significantly contribute to early diagnostics and also the treatment of this disease.

Introduction Despite significant progresses in the diagnosis of myocardial infarction and the development of reperfusion treatment methods, heart failure still often complicates its course. There are three types of postinfarction heart failure: occurring in the acute period, during hospital treatment and after discharge. Factors contributing to heart failure during hospitalization for MI and after discharge include comorbidity of the patient, worsening of pre-existing CHF and comorbidities. In the last decades we can observe higher level of myocardial percutaneous coronary intervention (PCI), improvement of pre-hospital care, which decreased mortality and HF; however, the proportion of HF patients with preserved ejection fraction increased. All these factors determine the urgency of the studied problem. Purpose of the study To identify the most significant factors contributing to the development of acute and subacute heart failure after myocardial infarction Materials and methods Retrospective and prospective non-randomized parallel-group analysis of 186 suffered MI (mean age 63.5 y) during one year was performed in this work, and in the main group of patients (86 patients) at 30 days after MI, chronic heart failure over 2F by NYHA was confirmed, and in comparison group (100 patients) CHF was either absent or did not exceed 2F by NYHA. The diagnosis of MI and CHF was made according to national and European guidelines. Both groups received standard therapy for CHF: ACE inhibitors/angiotensin 2/angiotensin receptor antagonists and neprolysin inhibitor (ARNI), β-blockers, mineralocorticoid receptor antagonists (AMCR), SGLT2-receptor inhibitors; anticoagulants, antiplatelet agents, statins, diuretics if necessary were also used. One year after discharge, clinical outcomes were assessed: cardiovascular mortality, repeated hospitalizations due to decompensation of CHF, death from other causes, stroke, repeated myocardial infarction, unscheduled coronary revascularization; telephone contacts were made every month, repeat visits to the clinic - one year later. The results were based on the information collected in the course of telephone contacts and via e-mail; hospitalizations were also monitored by querying the databases of medical institutions.

Several attempts have been made to refine selection criteria for cardiac resynchronisation therapy (CRT) in heart failure patients with reduced ejection fraction (HFrEF). Previously proposed parameters probably do not sufficiently reflect the underlying mechanical dyssynchrony of the left ventricle (LV). Earlier work of our research group suggests that better candidate selection can rely on the direct observation or measurement of this LV mechanical dyssynchrony by means of non-invasive imaging. In this study apical rocking and other non-invasive measures of LV mechanical dyssynchrony will be applied to evaluate regional myocardial workload and metabolism, and determine their predictive value in CRT response.

The purpose of this study is to evaluate whether vepoloxamer can provide a blood chemical marker and functional benefit to damaged heart muscle cells. This will be evaluated by measurement of blood-based laboratory markers, exercise tolerance, and echocardiograms. In addition, the safety and blood levels of vepoloxamer in subjects with chronic heart failure will be evaluated.

This was a multicenter, randomized, double-blind, crossover, placebo-controlled, Phase II clinical study that evaluated the effect of serelaxin versus placebo (both in addition to SoC) on the release of hs-cTnI, in patients with CHF after an exercise testing session.

The purpose of this study is to evaluate the effect of in-hospital diagnosis and treatment of sleep disordered breathing (SDB) on post-discharge mortality and readmissions in- hospitalized patients with acute heart failure syndrome and reduced ejection fraction (HFrEF).

Patients with HFpEF suffer from exercise intolerance, increased risk for hospitalization and mortality, and poor QOL. Unlike patients with HFrEF, no drug or device therapies appear to be consistently beneficial in treating these problems. However, increasing evidence suggests that exercise training is effective for both partially reversing exercise intolerance and improving quality of life in these patients. Most such trials to date have been conducted in controlled research setting, versus integrating these patients in to a standard CR program. Also, since functional capacity is related to outcomes in these patients, exercise strategies aimed at further improving fitness are warranted. One such strategy is using higher intensity interval training (HIIT) in the CR setting, a strategy shown to be effective in patients with other types of CVD. This project is designed to test the feasibility of incorporating these patients into the CR setting, and training them using a methodology (i.e., HIIT) already shown to yield (in other patients with CVD) greater gains in fitness when compared to what was achieved using standard MCT alone.

This was a multinational, multicenter, randomized, open-label study to confirm and expand the efficacy, safety and tolerability evidence of 48 hours intravenous infusion of serelaxin (30 micrograms/kg/day) when added to Standard of Care (SoC) in patients admitted to hospital for Acute Heart Failure (AHF).

The purpose of this study is to determine if analysis of heart ultrasound images with new software programs will provide better understanding as to the specific heart problems that lead to symptoms of heart failure.

Premature ventricular contractions (PVC) are a very common irregular heart beat (arrhythmias) even in patients without heart disease. Frequent PVCs are thought to occur in about 1-4% of the general population. Many patients with PVCs complain about skipping of their heart (palpitations), shortness of breath and feeling tired. In some patients PVCs may also result in weakening of the heart muscle (heart failure), which might be reversible with suppression of the PVCs.
