Filter by:At present, there is some clinical data for different functional response to beta-blockers associated with beta-adrenergic receptor polymorphisms. But there has been no data reported, about the incidence of beta-adrenergic receptor polymorphism and association with beta-adrenergic receptor polymorphism and response to beta-blocker therapy in Korean heart failure (HF) subjects. This single-arm, open-label, multicentric study is designed with the purpose of analyzing the association between genetic polymorphism of beta-adrenergic receptor and the effects of beta-blocker (bisoprolol) in Korean HF subjects.
The renin-angiotensin system (RAS) is a regulatory system that plays an essential role in patients with chronic heart failure (CHF). Plasma renin activity (PRA) is a strong and independent predictor of outcome, also in the presence of ACE inhibitors (ACE-i) and/or angiotensin receptor blockers (ARBs). Recently, it has been shown that vitamin D regulates renin transcription by activating the vitamin D receptor (VDR). Thus, specific activation of the VDR represents a novel target for therapeutic intervention in CHF. Currently, clinical data are lacking. The investigators aim to investigate the effect of the administration of vitamin D in patients with CHF.
Chronic heart failure (CHF) is a common syndrome characterized by several central hemodynamic and peripheral vascular and muscle abnormalities including autonomic imbalance, neuro-hormonal over-activation and decreased oxidative status. In patients suffering from CHF, exercise confers several beneficial effects on the cardiovascular and peripheral systems, mainly by continuous aerobic training. However, interval aerobic training has also been validated as an alternate form of training that increases the exercise capacity of patients who are in CHF. Recent studies have suggested that resistance training alone or as a complementary program besides the traditionally aerobic continuous training might exert favorable effects. However, little it is known about the combined effects of interval and strength training in CHF patients. Aim of this prospective randomized controlled study was to investigate the effects of combined interval and strength training comparing to interval training alone in CHF patients.
The purpose of the study is to assess whether primary care physicians may uptitrate recommended drug therapies in stable heart failure patients if educational material and specialist support including phone or mail consultation are provided
The purpose of this study is to discover whether the inhibition of the xanthine oxidase with allopurinol leads to a reduction of the production of oxygen free radicals in patients with CHF and thereby improves characteristics of oxydative metabolism, peripheral blood flow, immune function and functional status.
The purpose of this study is to determine whether treatment with candesartan cilexetil for at least 6 months in patients with chronic heart failure improves clinical signs and symptoms of chronic heart failure.
The study investigates the safety and effectiveness of a 12 week endurance training program for patients with chronic heart failure
The DREAMING clinical trial is part of the DREAMING project, which has the objective to demonstrate that the DREAMING platform consisting of integrated health monitoring, alarm handling and videoconferencing services produces clinical benefits to its users and economic benefits to the health authorities. The study evaluates the long-term (30 months) effect of continuous use of the DREAMING subsystems and is testing the hypothesis that such use is superior to usual care alone in reducing the deterioration of health related quality of life that is associated to age and chronic disease. It also tests the hypothesis that the DREAMING environment is superior to usual care in delaying the transfer to nursing or elderly homes and in reducing the incidence and duration of hospitalisation episodes. The trial will also evaluate the cost-effectiveness of the DREAMING platform. Outcomes are assessed in six different health care systems (Denmark, Estonia, Germany, Italy, Spain and Sweden) and will represent a basis for the adoption of DREAMING services by the respective health authorities.
The study will assess the effects of 36 weeks of treatment with LCZ696 compared to valsartan on N-terminal pro-Brain Natriuretic Peptide (NT-proBNP) in patients with chronic heart failure and preserved left-ventricular ejection fraction.
Only few prospective studies systematically investigated the prevalence of sleep disordered breathing in patients with stable chronic heart failure. Furthermore there is no report on the incidence rate of sleep disordered breathing in this population. This is a prospective multi-centre study of sleep-disordered breathing in 200 patients with stable moderate-to-severe chronic heart failure. Eligible patients will undergo overnight full-night polysomnography, lung function testing, laboratory measurements, and hemodynamic recordings. Measurements will be repeated at 6 months interval for a follow-up period of two years irrespective of the presence or absence of sleep disordered breathing. The primary outcome variable for this study is the prevalence of sleep disordered breathing in the study population. Secondary outcome variables include the 2-year incidence rate of sleep disordered breathing, quality of life measurements, exercise capacity, sleep quality, hemodynamic measurements, and laboratory markers of neurohumoral activation, systemic inflammation, and endothelial function in the study population.
