Active clinical trials for "Heart Failure"

This project deals with exercise in acute heart failure in three different groups (conventional medical treatment; exercise with non-invasive ventilation and exercise with placebo of non-invasive ventilation).

The purpose of this study was to determine the safety and tolerability of CLR325 intravenous (i.v.) infusion in patients with stable heart failure to determine if further clinical development of the drug in this indication was warranted.

Cardiac resynchronization therapy (CRT) is known to result in significant improvement in the symptoms of selected patients with heart failure, and to reduce hospital admission and death rates in these patients. CRT can improve cardiac function by improving the coordination of the heart beat using a special pacemaker. This requires a wire in the coronary sinus, one of the veins running around the outside of the heart, to stimulate the outside of the left ventricle (main pumping chamber). There are two particular issues with this standard technique. In some patients it is not possible to get the wire into the coronary sinus due to difficult vein shapes, and in others the wire can be put there, but it does not end up in a suitable position to act on the heart enough to improve heart function. This is thought to be a major part of the reasons why one in four patients does not improve with CRT ("non-responders"). The investigators have developed a novel method of pacing the left ventricle of the heart by putting the wire through a tiny hole made in the muscle between the left and right ventricles and pacing the inside surface of the left ventricular chamber. This will allow patients in whom the coronary sinus cannot be used to have CRT. The investigators will also offer it to patients who have not improved with CRT, as there is evidence that they may respond to this procedure due to physiological benefits from pacing the inside rather than the outside and also the ability to steer the lead anywhere on the inner surface. The investigators have performed this new procedure in a small number of patients already. This study will allow closer follow-up of more patients, and also investigation of ways to optimize results of the procedure for these patients.

Heart failure (HF) is a major global public health issue which also affects Asia. Data from the National Registry of Disease in Singapore shows a 9.4% rise in HF admissions in public hospitals from 2008 to 2009 (4140 to 4530). Anaemia (low blood Haemoglobin level) is a common problem occurring in HF, ranging from 14% to 56% in outpatient registries and clinical trials. Anaemia exacerbates the basic symptoms of HF of dyspnea and exercise intolerance, thereby reducing quality of life (QoL). However, recent approaches aimed at improving and normalizing Haemoglobin have been unsuccessful.Novel approaches are required to address this problem. Iron deficiency (ID) is a well-understood cause of anaemia. ID without overt anaemia may be present in HF patients. A recent study by Jankowska et al published in 2010 of 546 HF patients showed a 37% prevalence of ID, regardless of Haemoglobin level. This was associated with worse outcomes including impaired exercise capacity. The presence of ID indicates a higher likelihood of deteriorating and dying early. A landmark study published in the New England Journal of Medicine (The Ferinject Assessment in Patients with Iron Deficiency and Chronic Heart Failure (FAIR-HF) study) showed that HF patients who were treated with IV iron in the form of Ferric Carboxymaltose (FCM) had better outcomes, including improved exercise capacity, overall function, and quality of life. There is a lack of contemporary data on ID in HF patients in Asia, including data on treatment with this novel IV iron FCM. Hypothesis We hypothesise that treating ID in HF patients in Asia using FCM will improve outcomes including exercise capacity, quality of life, overall functional status, and the need to be hospitalised for complications arising from HF.

The aim of this clinical trial is to evaluate the effect of obstructive sleep apnea syndrome (OSAS) treatment in heart failure patients following coronary artery bypass graft (CABG) surgery or other coronary reperfusion.

It is established that at a serum concentration 0.5-0.9 ng/ml digoxin is effective in patients with heart failure, especially in the presence of atrial fibrillation (AF). It is the claimed that ivabradine by lowering heart rate reduces symptoms and improves clinical outcomes in patients with heart failure. The effect of ivabradine and digoxin in heart failure was compared. Patients 22 patients with ischemic heart failure, AF, and diastolic dysfunction with preserved left ventricular systolic function were treated with digoxin and ivabradine for 3 months, according to a randomization cross-over design. Collected data Medical history, physical examination, laboratory (including proBNP and serum digoxin concentrations), ECG, 6-minute walk test, and echocardiographic data (LVEF, LAVi, e/e1 ratio).

The purpose of the study is to assess the feasibility and safety of a transplantation of cardiac-committed progenitor cells derived from human embryonic stem cells in patients with severe heart failure.

The purpose of is to test the effects of a 6-month nutrition intervention of dietary sodium reduction combined with supplementation of lycopene and omega-3 fatty acids on heart failure symptoms, health-related quality of life, and time to heart failure rehospitalization or all-cause death.

The number of people with heart failure is increasing in the western world. Mainly due to better treatment of myocardial infarctions and ageing of the population. The amount of health care workers is unfortunately not increasing. We want to investigate how two electronic devices (a website and an interactive web-based platform) influence the self-care, quality of life, hospitalizations and mortality by delivering care from a distance. We also want to investigate if a higher quality of care is delivered despite of less frequent visits to a nurse and/or doctor. The study takes place in the Netherlands and is a randomized trial. Patients with heart failure, registered by an outpatient heart failure clinic or general practitioner can take part. They will be randomized to 3 groups: group 1 receives standard care, group 2 receives standard care with the website, group 3 receives an adjusted care pathway, with both the website and the interactive web-based platform connected to a telemonitoring system. In this group all routine consultations with heart failure nurses and general practitioner will be substituted by this device.

The primary objectives of this study are (i) to select an oral modified release (MR) formulation and dose of omecamtiv mecarbil for chronic twice daily (BID) dosing in adults with heart failure and left ventricular systolic dysfunction and (ii) to characterize its pharmacokinetics (PK) over 20 weeks of treatment.
