Active clinical trials for "Heart Failure"

The purpose of this study is to determine whether continuing or discontinuing furosemide (a diuretic) on the day of elective noncardiac surgery for those who take furosemide on a chronic basis, causes more intraoperative hypotension (low blood pressure) during surgery. Our hypothesis is that the usual practice of continuing furosemide on the day of surgery would contribute to more hypotension during surgery than discontinuing furosemide.

The purpose of this study is to evaluate dyspnea improvement and other parameters of efficacy and safety in acute heart failure (AHF) patients receiving an intravenous (IV) infusion of clevidipine in comparison to standard of care (SOC) and placebo.

This is a single-center, non-randomzied pilot study investigating a combination of targeted therapies as possible treatment for heart failure with preserved ejection fraction (HFpEF). The study interviention is a Low-Dose, Triple Polydiuretic Therapy (LDTPT, or polydiuretic) including loop diuretic (bumetanide), mineralocorticoid receptor antagonist (eplerenone), and Sodium-glucose co-transporter 2 inhibitors (SGLT2i) therapy (dapaglifozin).

This study aims to investigate the effects of treatment with intravenous ferric carboxymaltose on exercise tolerance measured as VO2peak in patients with HFpEF and iron deficiency, compared to placebo.

Congestive heart failure (CHF) is a disorder of the heart when structural or functional heart disease impairs the heart's ability to work properly. In developed countries, the prevalence of CHF in the general population is around 1-2% (depending on the definition used) and the prevalence of CHF in people aged 70 years and older is ≥ 10%. The cumulative 5-year mortality of patients with CHF is about 50%. According to different studies, the prevalence of the early repolarization pattern (ERP) in the 12-lead electrocardiogram (ECG) in the general population is 2-31%. Although ERP in ECG have been considered as benign finding for many years, an increasing number of studies have been conducted in recent years to demonstrate an association of ERP in ECG with sudden cardiac death, mainly through ventricular arrhythmias in previously healthy individuals or those with structural cardiac pathology. New studies are also being performed to support the association of ERP with the progression of CHF. Although the prevalence of ERP in the general population is not very high, the knowledge that ERP lead to a higher risk of sudden cardiac death and development of CHF lets physicians tailor patient care and follow-up, and treatment at a very low cost because ECG is a cheap, simple, and widely available diagnostic test. Impedance cardiography (ICG) is another safe, non-invasive, cheap, routine diagnostic method based on the detection of changes in thoracic bioimpedance during heartbeat. The aim of the present study is to evaluate the diagnostic and prognostic significance of ICG and ERP in congestive heart failure patients and to compare it with other non-invasive CHF diagnostic methods. The investigators hypothesize that ERP and changes in ICG readings may be used as a cheap, safe, non-invasive and widely available diagnostic and prognostic methods in patients with congestive heart failure witch help physicians tailor their patient follow-up and treatment accordingly. The participants of the study are those who are hospitalized due to the flare-up of congestive heart failure. All of the participants will undergo routine tests. They will also undergo an ICG witch is not a routine test in the research center.

The purpose of this study is to examine the feasibility of providing a problem-solving therapy-based intervention to improve both depressive symptoms and heart failure self-care specifically after hospital discharge. This is because the period after hospital discharge is critical to long-term recovery, overall quality of life, and prevention of adverse outcomes, such as hospital readmission.

The purpose of this feasibility study was to obtain pilot data, as the basis for a future, larger investigation, testing the impact of an innovative training camp intervention called HEART CAMP (Heart failure Exercise And Resistance Training CAMP) to teach HF patients how to exercise and self-manage exercise behavior over time. The study assessed the feasibility and adequacy of the intervention, the data collection plan, and the reliability and sensitivity of the outcome measures. The 6-month intervention was based on a training camp model to teach HF patients how to exercise in a fun, group-oriented atmosphere. Subjects interacted and exercised in small groups with an exercise physiologist and nurse to guide activities. The dosage of the intervention (frequency and amount of direct guidance from the exercise physiologist and nurse) decreased over the 6 months in order to increase subject's independence and promote long-term adherence to exercise. The intervention incorporated use of computerized data files to monitor exercise behavior, compare exercise performance to individualized goals and provide feedback as strategies to foster adherence and self-management of exercise behavior.

The aim of the present project is to compare the acute and chronic effect of stair descending versus stair ascending exercise on muscle damage and performance in elderly males with chronic heart failure.

Central Sleep Apnoea (CSA) affects up to half of patients with severe heart failure and is associated with a poor prognosis. CSA is manifest as episodes of deep breathing interspersed with very shallow or absent breathing and is largely due to an exaggerated response to rising carbon dioxide in the blood, which normally drives how hard we breathe. Cardiac Resynchronization therapy (CRT), in which a pacemaker is implanted to improve co-ordinated contraction of the heart, has been shown to reduce the severity of CSA in some patient groups. We aim to determine whether this improvement is due to normalization of the body's response to carbon dioxide in the blood. Our hypothesis is that CRT improves CSA by normalizing the brain's response to carbon dioxide.

The purpose of the trial is to investigate the safety and effectiveness of renal denervation for the treatment of chronic heart failure (CHF).
