Active clinical trials for "Heart Failure"

The purpose of this study is to determine whether increasing hemoglobin concentration in patients with heart failure and anemia will improve the patients' functional status, including exercise tolerance and New York Heart Association (NYHA) classification.

The purpose of this study is to compare dosing compliance between study patients taking controlled release carvedilol once a day, and study patients taking immediate release carvedilol (Coreg) twice a day.

This international study is assessing if repeat adjustment of the timing between the three leads in a cardiac resynchronization therapy (CRT) defibrillator will increase the likelihood of benefit (symptoms and heart function) compared to usual device programming. The hypothesis is that QuickOpt facilitated serial optimization of sensed atrioventricular (sAV), paced atrioventricular (pAV), and inter-ventricular (VV) timing in the initial 9 months following successful CRT will increase the rate of clinical response and structural remodeling at 12 months compared to usual care.

Despite advances in medical therapy for patients with heart failure, one-third of patients remain limited by fatigue and shortness of breath. Our previous study concluded that one dose of sildenafil (Viagra) lead to an improvement in heart pressure and exercise capacity. Currently sildenafil is not FDA approved for the treatment of heart failure. The purpose of this study is to determine if treatment with sildenafil for 12 weeks in patients with heart failure can improve exercise capacity and quality of life in people with heart failure.

The purpose of this study is to determine whether treatment with Toprol-XL for 12 months in asymptomatic heart failure subjects will improve their heart structure and thus prevent the progression to symptomatic disease.

This is a randomized, double-blind, placebo-controlled, parallel-group forced up-titration study. Randomization will be stratified according to the patient's baseline serum sodium concentration (137-144 and <137 mmol/L). The dose of study drug will be increased to the next level on Day 15, and the total duration of the double-blind treatment period is 120 days.

The objective of this project is to determine if Neo40, a nitric oxide generating lozenge, when consumed twice daily by subjects with HFpEF, will increase exercise tolerance, decrease symptoms and improve quality of life for patients.

FEAST-HF is a single-centre clinical trial in ambulatory patients with chronic HF to evaluate whether dietary supplementation with acacia gum reduces HF-related biomarkers NT-proBNP and ST2 and how the gut microbiome responds to dietary supplementation with acacia gum. The hypotheses of this study are 1) that changes in the gut microbiome will be correlated with a reduction in NT-proBNP and ST2 in patients with HF after treatment with acacia gum, and 2) gut microbiome configurations (composition, diversity), stability and function (gene content) will be significantly altered in patients with HF in response to acacia gum.

This clinical research study is being conducted in multiple hospitals in Belgium and approximately 519 patients with acute decompensated heart failure are expected to participate. Large-scale research shows that 90% of the physicians treat volume overload with high doses of loop diuretics. However, there is not a lot of scientific data available regarding the optimal doses of these diuretic medications. In addition, it is observed that a lot of people, treated with these drugs, are being readmitted to the hospital due to a new episode of heart failure. The hypothesis of this study is that the volume overload could be better treated when patients receive a combination of different types of diuretics. Additionally, the total dose of the administrated diuretics might be lower this way.

Incretin therapy is a treatment for type 2 diabetes (T2DM) affected by heart failure (HF). In this study the investigators will recruit T2DM patients affected by HF with depressed ejection fraction and treated by Cardiac resynchronization therapy (CRT). These patients will randomly be treated by incretin v/s conventional hypoglicemic drugs. In this patients investigators will report at follow up CRT-d responders rate, mortality, and hospital admission for HF worsening. Incretin may reduce hospital admissions for HF in T2DM v/s conventional hypoglicemic drugs.
