Active clinical trials for "Heart Failure"

Association between serum magnesium and clinical outcome in patients with acute MI (AMI) with 1 year follow-up in 300 patients in regions supplied by desalinated drinking water (DSW) (Sheba MC) and 150 patients in regions with non-desalinated drinking water (DW) (Nahariya MC).

This study will evaluate the Telehomecare (THC) Program offered to patients with heart failure or chronic obstructive pulmonary disease across the Central West, Toronto Central and North East Local Health Integration Networks in Ontario. It will explore the opinions and experiences of patients, providers, technicians and administrators involved with THC Program in order to provide stakeholders with information about the processes and organizational factors impacting the program's adoption, the experiences of its participants, impact on patient outcomes, costs to the health-care system and who is benefiting the most from participating. These factors will be determined using semi-structured interviews, surveys, and observation of practices of everyone involved with THC. The study will also evaluate patient data to determine changes in patients' utilization of healthcare services.

Heart failure is a common problem with a prevalence of 1-2% in general population and a major cause of mortality,morbidity and impaired quality of life. Anemia is afrequent comorbidity in stable heart failure patients and it increases morbidity in terms of frequent hospital admissions,impaired exercise capacity,poor quality of life ,and increased mortality

The NanoSense study is a multi-center, prospective, non-randomized, observational, feasibility, non-significant risk study. The NanoSense study will enroll up to 500 subjects in up to 10 centers in order to collect data which includes at least 150 heart failure hospitalizations in participating subjects.The duration of the NanoSense study is expected to be 2 years. The study device is the Wearable Congestive Heart Failure Management System (WCHFS, also known as SimpleSENSE)

The purpose of this prospective, non-randomized, single-arm, research study is to evaluate the accuracy of acutely extracting respiratory rate and tidal volume from implanted cardiac device impedance in subjects with heart failure. In addition, to assess the feasibility of extracting respiratory rate from device EGM under various conditions.

The onset and course of heart failure (HF) is triggered by a complex regulatory network that includes stressors (pressure overload by individual anatomic hemodynamic settings), intrinsic (genes), environmental (regulating epigenetics), and modifying factors (such as hor-mones and the immune system). SMART aims to establish individualized strategies for the prevention and management of HF by early detection of the physiological, genomic, proteo-mic and hemodynamic mechanisms that lead from onecommon cause of ventricular dysfunction (pressure overload) to maladaptive remodelling and irreversible HF. To cope with the complexity of HF, SMART will interrelate models describing the interplay between ge-nome, proteome and cell function, regulating hormones, tissue composition and hemody-namic whole organ function up to a whole body description of a patient and patient cohorts. The ultimate goal is to demonstrate proof-of-concept tools for predicting disease evolution and efficacy of treatment in a given patient. To achieve this task SMART will apply A modelling framework that couples multi-scale mechanistic models with in-depth genome/proteome, cell physiology and whole organ (biomechanical and fluid dynamic) models Subsequently, investigate methods validity and relevance for "quantitative prediction" of treatment outcome in a clinical proof-of-concept trial (demonstrator) of patients with aortic valve desieases.

Patients with poor heart function can, in certain situations, have a further weakening of the heart muscle such that it becomes difficult to provide enough blood to the brain and other organs. In these cases, heart function can be supported by the use of medicines or heart pumps. One of the most widely used medicines is Dobutamine, given as an infusion (a drip). Although Dobutamine has been in use for decades and does improve blood flow to the organs, previous studies have not shown any impact on recovery of heart muscle function and survival. Key to unravelling this discrepancy is to understand the precise effects of Dobutamine on the oxygen supply to, and oxygen usage by, the heart muscle. We also aim to find out whether simultaneous infusion of another drug called Nitrite (naturally occurring substance that is found in beetroot for example, much like GTN) can enhance the beneficial effects of Dobutamine on the oxygen supply-demand balance of the heart. In recent years, major advances in technology mean that it is now possible to obtain this information in patients undergoing coronary angiography procedures by making detailed measurements of heart muscle function and blood flow in the heart arteries using a conductance catheter (measures volume and pressure within the main pumping chamber of the heart) and the Combowire (dual pressure and flow sensor tip angioplasty guidewire). The aim of this study is to understand the effect of a brief infusion of Dobutamine and nitrite on heart muscle function, oxygen supply and oxygen usage through this use of this technology, directly following the patients routine coronary angiogram. Patients will have these measurements taken using the technology described above during the infusion of both dobutamine and nitrite, inserted through blood vessels that reach the heart.

Heart failure (HF) is a continuously growing public health problem. The study aim to provide novel insights into the role of amino acids in pathogenesis of heart failure, to obtain a better understanding of cardiac ryanodine Receptor 2 role as an essential player in excitation-contraction coupling in pathogenesis of heart failure and clarify the potential value of these markers as targets for heart failure therapy

In decompensation of heart failure, it may occur low cardiac output. For patients in this situation, the use of inotropic may be necessary. Prolonged intravenous infusion of inotropic agents can lead to phlebitis in peripherally venous access. On the other hand, central venous access presents complications inherent in the procedure. The peripherally inserted central catheter (PICC) may be an option in this situation. The present research project is a randomized clinical trial to evaluate the incidence of phlebitis by using the PICC in comparison to the peripheral venous access. The criteria for inclusion are: advanced congestive heart failure, in use of intravenous inotropic; platelets > 50.000 mm3 and left ventricular ejection fraction (LVEF) < 0.45. Patients will be randomized to receive the PICC or keep the peripheral venous access. The main outcome will be the occurrence of phlebitis. The sample size will be of 40 patients for each group (PICC and control). The data will be analyzed by logistic regression. Will be considered significant P 0.05.

The purpose of this study is to determine whether lipid levels are related with incidence of atrial fibrillation in Patients with chronic heart failure.
