Filter by: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.

The investigators are examining the relationship between heart rate and heart contraction in patients with heart failure and pacemakers, aiming to improve quality of life.
The purpose of this cross-sectional comparative 2x2 trial study is to compare the degree of insulin resistance, myocardial function and selected metabolic parameters and to explore the pathophysiological mechanisms by which insulin resistance is implicated in development of chronic heart failure (HF) in patients with type 2 diabetes and prediabetes (T2D). Investigators hypothesize that patients with heart failure will be insulin-resistant and will display metabolic abnormalities as patients with diabetes.
The purpose of this study is to understand the behaviour of certain blood markers in patients with heart failure who undergo a cardiac device implantation procedure called cardiac resynchronization therapy (CRT). CRT is an effective treatment for heart failure, but up to 30% of people do not respond and have poor outcomes (1,2). Despite extensive investigation, identifying these patients continues to be a challenge. The study intends to describe the changes in these blood markers before and after CRT and to examine any potential clinical value. The idea behind the study is that these blood markers alter in heart failure and change with CRT implantation. Furthermore the pattern of marker expression before implant and after may predict response and outcome.
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.
The objective of this study, is to assess the safety and performance of an interatrial shunt when implanted in patients with severe chronic heart failure.
Cardiac resynchronization therapy (CRT) is a well-established treatment for patients with severe systolic heart failure (HF) and ventricular desynchronization. Despite the consistently observed structural and functional improvements as well as reductions in HF events and mortality in large multicenter randomized trials, 30% patients remain classified as nonresponders. Present evidences showed that QRS duration was the most effective parameter to predict responsivity of CRT in patients with severe HF. But some studies showed that QRS duration could be influenced by obesity and gender. Accordingly, the simple QRS interval width of body surface electrocardiograph should not be the most satisfactory parameter for screening patients suitable for CRT. Recent study showed that left ventricular electrical delay, as measured by the time from the onset of QRS to the LV electrogram peak (QLV), predicted CRT response. At long QLV intervals, atrioventricular optimization (AVO) can increase the likelihood of structural response to CRT. However, it is unclear whether it is suitable for Chinese patients. The investigators would like to validate this relation in a Chinese population and explore if a corrected QLV might do better to predict the responsivity of CRT.
The main objective of the study is to evaluate the effect of telemonitoring on mortality and rehospitalization due to heart failure on patients with chronic heart failure which have follow an educational program compared to a conventional follow-up during 1 year. The secondary objectives of the study are : - Evaluate the cost of health - Qualitatively evaluate telemonitoring on uses - Evaluate quality of life
Management of chronic heart failure (CHF) is a major public health problem. It is associated with high mortality, frequent hospitalization and represents a large cost to the health care system. Both pharmacological and non-pharmacological intervention haven't shown to be effective in reducing morbidity and mortality of these patients when able to modulate the activity of neuro-hormonal systems among them the sympathetic nervous system. Recent data have emphasized the potential role of sympathetic renal denervation in patient with hypertension. CHF per se but even more CHF associated with comorbity lead to significant increase level of sympathetic tone. This is largely induced by autonomic dysfunction such as chemo or baroflex abnormalities. These patients usually suffer from conditions which do not allow upgrading and adapting drugs to their sympathetic condition. Hence CHF patient with chronic kidney disease, anemia or both have markedly high sympathetic activity and cannot be exposed to higher level of RAS Blockers or beta blocker due to their renal dysfunction, they thus remain with an elevated sympathetic activity worsening symptoms and prognosis. Chronic heart failure affects around 100 million people worldwild imposing a significant burden on health care system throughout the world. Even though symptoms are improved by heart failure therapy, they remain significantly disabling for many patients. Chronic over activation of the sympathetic nervous system is a major component of heart failure and involves efferent and afferent pathways between brain and many organs. A new therapy directly targeting nerve traffic-renal artery denervation- has been shown to be effective in drug resistant hypertension, with an average drop in blood pressure of 33/12 mm hg. The cardiologists team of the private hospital Arnault Tzanck is willing therefore to conduct a study in 12 patients with chronic systolic heart failure undergoing bilateral renal denervation with an intensive protocol of observation and assessment compring a 3 day hospital stay post procedure 3 and 6 months of regular outpatient follow-up.
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.
