Filter by:The purpose of this study is to evaluate the management of chronic heart failure patients with atrial fibrillation, to collect data on compliance with clinical guidelines and the prevalence of long-term anticoagulant therapy,complications. The results will be used to develop most rational therapeutic and diagnostic strategies to improve clinical outcomes of such patients.
Iron deficiency may contribute to exercise intolerance by altering mitochondrial oxidative capacity in skeletal muscle. Functional iron deficiency is common in heart failure patients, but the relationship to exercise intolerance and mitochondrial oxidative capacity is unknown. This is a pilot study to determine the feasibility of the use of specialized 31P-MRS and MRI techniques for measurement of skeletal muscle bioenergetics in patients with heart failure with and without functional iron deficiency.
Known before diagnosed heart failure and used diuretic therapy patients will be admitted in this study.The objective of this work is whether the Inferior Vena Cava Ultrasound can be used for management of Acute Heart failure therapy. And investigators will calculation correlation of extracted urine amount with Inferior Vena Cava diameter change. Researchers will not interfere to standard recommended treatment protocol, researchers will correlated the urine amount and changed vital signs with therapy with Vena cava inferior diameter.
This study will address whether the additional use of Intravenous (IV) iron on top of standard care will improve the outlook for patients with heart failure and iron deficiency. One group of participants will receive treatment with iron injections and the other group will not receive any iron injections.
Breathlessness is a common and distressing symptom in patients with advanced diseases like cancer, chronic obstructive pulmonary disease (COPD), chronic heart failure (CHF) or lung fibrosis, which broadly impacts on patients' quality of life and may result in high burden for carers. This single-blinded randomized controlled fast track trial evaluates the effectiveness of a multi-professional breathlessness service in patients with advanced and chronic diseases. The intervention group will get immediate access to the breathlessness service whereas the control group will receive standard care and get access to the service after a waiting time of eight weeks. Primary endpoints are mastery of breathlessness and quality of life, measured with the CRQ (Chronic Respiratory Questionnaire) as well as the reduction of symptom burden of patients and burden of carers. The evaluation of the cost effectiveness of the breathlessness service from the perspective of the German health system is a further study aim.
This study, which will be conducted at 23 sites representing the determined NUTS-1 regions in Turkey, in which all patients who were admitted to clinic or were hospitalized with Heart Failure (Acute or Chronic) diagnosis will be enrolled into the study, for a month and on a day of the week which will be determined by the site itself, is a national, multi-center, observational, epidemiological and cross-sectional study. This study is a local study which is planned to be conducted only in Turkey. Included patients of the study will be clinically evaluated by the physicians who are maintaining them and will receive the standard medical treatment which is determined by their physicians in normal life conditions. No experimental intervention or treatment will be received by patients in relation to the enrollment to this study. Therefore, this study does not contain a protocol or a pre-determined visit flowchart. However, patients with Heart Failure diagnosis should grant their consent to the retrospective utilization of their data and questions which will be asked to them about their disease history. Provided that the study's design is non-pharmacological observational, investigators will treat and follow the patients in accordance with their own medical decisions and their best clinical experiences.

Applying modern technology of data collecting, monitoring, transmitting and analyzing in order to implement a novel (hybrid) model of comprehensive home-based cardiac rehabilitation in heart failure patients.
Heart failure (HF) remains to have a poor outcome. Even though recent advances in HF led to a reduction of morbidity and mortality, improvement in outcome is much less than expected based on large randomized trials. Various reasons may be responsible, such as complexity of disease and comorbidities, inadequate diagnosis and inappropriate treatment. So far, little attention has been paid on patients seen in primary care. Also, HF care mainly focuses on the individual patient-doctor relationship. However, the increasing complexity prevents individual physicians from covering all aspects of care. Consequently, multiple stakeholders are involved, including both general practitioners and specialists. Still, the relative role, the interaction between them and the processes included are hardly defined. These aspects may not only be relevant for patient care, but also for the setup of health care systems. Whereas multidisciplinary team should resemble a seamless system across primary and hospital care, there is a scarcity of research considering how these disease management programs perform, in what form they should be offered, and what care and support patients and caregivers would benefit most.The INTERACT-in HF (Improving kNowldege Transfer to Efficaciously RAise level of Contemporary Treatment in Heart Failure) study is set up to determine and assess relevant factors of the quality of HF care. The study evaluates processes of HF care, role of relevant care givers and interactions between them. It collects data from individual patients to assess characteristics and management of contemporary HF patients. This is performed in different countries (the Netherlands, Belgium and Germany) to analyze decision making with respect to diagnostics and treatment.Cross-sectional mixed-methods are used. Patients and their caregivers are interviewed. The patient is the central starting point. Then, the treating GP, cardiologist and HF nurse are interviewed. In parallel, retrospective data based on records from these patients are reviewed to verify data from interviews and to determine characteristics of them. Retrospective data of additional patients are collected to complete the picture of the current situation. These data will be used to define bottlenecks that prevent best clinical practice to be used in daily care at all levels, comparing practice in different countries.Thus, the proposal aims to better understand HF care, which will lead to a better care and finally to improved outcome.
The primary objective of this study is to demonstrate the superiority of ivabradine over placebo in the reduction of cardiovascular mortality or hospitalisation for worsening heart failure in patients with moderate to severe symptoms of chronic heart failure, a reduced left ventricular ejection fraction and currently receiving recommended therapy for this disease.
Cardiac resynchronization therapy(CRT) is recommended to reduce mortality and morbidity in chronic heart failure(CHF) patients New York Heart Association(NYHA) class III-IV who are symptomatic despite optimal medical therapy, with a reduced left ventricular(LV) ejection fraction(LVEF) and prolonged complex QRS. CRT improves the prognosis however, despite the improvement, all major trials have demonstrated that one third of the patients are non-responders to CRT. Three months after the CRT implant, the responders have a significant increase in endothelial function(EntF), a decrease in the LV end-systolic volume, and increase in LVEF, 6 minute walk test(6MWT), improvements in NYHA class and quality of life. It is currently unknown if adding an exercise training(ExT) program following CRT provides better clinical outcomes than CRT alone. Prior studies on CRT and ExT have been preliminary in nature, but suggest small improvements in functional capacity(FC). The correction of endothelial dysfunction is associated with a significant improvement in exercise capacity evidenced by a 26%increase in peak oxygen uptake. These findings are important because CHF patients with the greatest sympathetic activation and the most reduced EntF have the poorest prognosis. Our experience with coronary artery disease patients, and most recently data in patients with CHF show that an ExT program that combines aerobic exercise(AE) and resistance exercise training are more effective than an AE program alone, and the aerobic interval training showed better improvements than continuous endurance training. It is unknown how CHF with more severe functional limitations responds to ExT and, more important, the explanation of the physiological mechanism that can explain the improvements as a consequence of ExT. This lack of scientific information is urgent since this is the group of patients that normally is targeted for CRT. The investigators propose to use a stratified randomized longitudinal study to determine the additional effects of a 6 month ExT in addition to CRT in NYHA stage III-IV HF patients. The aims of the study are:1-to determine whether a long-term ExT program follow the CRT provides better clinical outcomes than CRT alone and 2-To identify the mechanisms of the hypothesize improvement. The results of this project will represent an important contribution by understanding the role of ExT after CRT NYHA stage III-IV heart failure(HF) patients, an understudied population with poor clinical outcome. Understanding the potential mechanisms associated with clinical improvement and outcome is essential for the rehabilitative process to develop new innovative therapies in this high risk population. The investigators will use state-of-art methods including an integrated assessment autonomic nervous system(ANS) and arterial function using 123I-MIBG scintigraphy.
