Filter by:This study is a prospective, randomized, double blind , controlled trial to assess the efficacy of intracoronary transplantation of autologous cardiac stem cells in 50 patients with ischemic heart failure.
Magnetic resonance elastography is a novel non-invasive MRI technique to obtain stiffness of soft tissues such as liver, heart, kidneys, etc. In this imaging technique a person is laid in an MR scanner and a paddle (plastic drum) is put on the area of interest to send sound vibration via a speaker placed outside the scan room which is connecting plastic drum via a plastic tube. These vibrations are scanned using MRI to estimate the stiffness of soft tissues such as liver, heart, kidneys, breast etc.
The investigators will evaluate the determinants of cerebral impairment in patients with non-ischemic heart failure compared to controls, and its relation to cognitive function. They hypothesize that patients with heart failure have impaired brain perfusion and hemodynamic factors are associated with cognitive dysfunction.
The purpose of this study is to determine the effect of fluid restriction and the neurohormonal mechanisms in the development of hyponatremia in patients with congestive heart failure and hyponatremia. The hypothesis is that strict fluid restriction leads to a larger increase in plasma sodium than standard treatment in patients with decompensated heart failure associated with hyponatremia. A secondary hypothesis is that the neurohormonal change is greater in patients treated with strict fluid restriction versus standard treatment.
The relationship between the activation of the vasopressin system and central hemodynamics in heart failure (including right and left heart filling pressures and cardiac output) is not clear. The investigators intend to examine the correlation between levels of copeptin and vasopressin and the central hemodynamic system in patients with advanced (class III or IV) heart failure. The investigators also aim to examine the relationship of selected cardiac biomarkers in blood and urine with cardiac filling pressures and cardiac output in patients with decompensated heart failure. The study population will consist of 30 patients admitted to the Department of Cardiology at Copenhagen University Hospital. Only patients for whom the attending cardiologist has already decided upon right heart catheterization for clinical/treatment reasons will be recruited for the study.
This study is being done to study how well the heart contracts and relaxes during exercise. In addition to traditional measures of heart function, we will use a new computer program that may improve understanding of why people feel shortness of breath or fatigue.
This is a placebo-controlled study to determine the effect of CLP in heart failure subjects with fluid overload.
One of the most cost effective intervention is to avoid unnecessary hospitalizations in the national health system. These unnecessary admissions are increasing for several years, reaching rates of over 30% in patients with chronic obstructive pulmonary disease (COPD) or heart failure at two months of hospital discharge. There is scientific evidence suggesting that a multidisciplinary intervention consisting in controling disease and stress associated with disease, and modifying eating habits could reduce the number of hospitalizations due to disease decompensation. The main objective of the study is to assess the rate of readmissions at year of multidisciplinary intervention in patients with COPD and / or heart failure. We will select 144 patients who will be randomized to two groups (control and intervention group) and they will be followed for 12 months through 4 visits (1 month, 3 months, 6 months and 12 months of hospital discharge). Patients assigned to the intervention group will be receive three educational sessions (one of them will be imparted by nursing, another by the nutritionist and the last one by the psychologist). In addition, patients with a BMI <20 and / or> 30 will receive a closer monitoring by the nutritionist). Patients assigned to the control group will receive usual care in clinical practice.
Levosimendan is a drug used in patients with heart failure and has several advantages over other heart failure drugs. A lot of research has been done with Levosimendan in Adults, and the way the body handles the drug (pharmacokinetics) and responds to the drug (pharmacodynamics) are well established. But, in children this information is lacking despite the fact that Levosimendan is increasingly used in children of all ages. The investigators aim to describe which Levosimendan dose leads to which drug levels in children of different ages.
The purpose of the study is to test a new medical device for optimizing treatment of heart failure and compare its effect on outcome of patients with a recent hospitalization for worsening heart failure
