Promoting Patient-Centered Care Through a Heart Failure Simulation Study
Heart FailureThe initial aim of this study will be to assess current methods of heart failure (HF) patient education in terms of patient satisfaction, level of preparedness for home, and care provider satisfaction. The second aim will be to design and create a "living with HF at home" simulation session. The third aim will test the hypothesis that hospitalized HF patients who receive education in a simulation room in addition to usual HF education will have improved qualitative and quantitative outcomes as compared to those who do not receive the additional education support.
Selection of Potential Predictors of Worsening Heart Failure
Heart FailureMulticentre study with the objective to correlate heart failure hospitalizations and deaths with Home Monitoring data in ICD/CRT-D recipients, in order to identify the combination of Home Monitoring data with the greatest sensitivity and specificity in predicting Heart Failure events. All data are prospectively collected.
The Increase Study. Effect of Incremental Versus Fixed Pump on Peak Oxygen Consumption in Heart...
Heart Failure.The purpose of the study is to examine the relationship between working capacity (peak oxygen consumption) and pump speed of continuous flow left ventricular assist devices (CF-LVADs)in heart failure patients. The hypothesis is that it is possible to increase peak oxygen consumption by incrementally increasing CF-LVAD pumpspeed during exercise. The study population will consist of severe heart failure patients with CF-LVADs treated at The Heart Centre of Copenhagen University Hospital Rigshospitalet.
Method To Measure Protein Digestion & Absorption
Chronic Heart FailurePulmonary Disorder1 moreThe aim of the present study is to validate a new method in healthy volunteers and those diagnosed with COPD and CHF that is able to measure protein digestion and absorption simultaneously. This method is used to quantify digestion and absorption in patients who are suspect of impaired digestion and absorption resulting in loss of nutrients.Findings may be used to develop treatment strategies to improve protein digestion and absorption in these patient groups.
Heart Failure Caregiver Study
StressDepressionFamily caregivers are vulnerable to health problems because of the stress and demands of their role as a caregiver. With the growing incidence of heart failure (HF) and the anticipated growth in the aging population, the number of HF caregivers is expected to rise. This study will pilot test a cognitive behavioral intervention designed to reduce stress among HF caregivers, which will ultimately contribute to promoting health and quality of life among HF caregivers and their loved ones with HF.
Evaluation of the Effects of Eccentric Muscle Training Versus Conventional Concentric Training in...
Chronic Heart FailureReconditioning to EffortThis is a single-centre open randomized parallel-group study. Patients will be selected at random to be included in group 1: eccentric rehabilitation or group 2: conventional rehabilitation. In addition, a group of healthy volunteers aged between 20 and 85 years will also be recruited. This group will make it possible to evaluate, during the two exercise sessions, mechanisms of adaptation linked to eccentric exercise vs concentric exercise.
A Pilot Trial of Patient Decision Aids for Implantable Cardioverter-Defibrillators (ICDs)
Systolic Heart FailureSudden Cardiac DeathThe purpose of this study is to test the acceptability and feasibility of a "toolkit" of patient decision aids (PtDAs) for heart failure patients who are considering an ICD implant.
Myocardial Lipid and Creatine of Heart Failure on MRS
Myocardial LipidThe objective of this 3-year project is to develop myocardial MRS, in particular lipid (triglyceride) and creatine resonances, as imaging biomarkers for patients with heart failure (HF). Investigators will elucidate how and, to what extent, lipid and creatine levels of the heart contribute to heart failure. The first year is a cross-sectional study. Investigators aim to compare the MRS of normal subjects and that of stable HF patients in recovery with normal or impaired ejection fraction (EF). Total 60 subjects will be enrolled, with 20 subjects in each group. In the 2nd and 3rd years, investigators plan a prospective longitudinal study of 40 subjects. Enrolled patients will be evaluated with cardiac MRS at three time points, i.e., disease onset, 6 months and one year after treatment, and will be followed up until the end of this project (1.5~3-year follow up). In total 120 MR scans will be performed in the 2nd and 3rd years. The resonances from cardiac MRS, including creatine and lipids, will be correlated with the disease course, patient biochemistry data and clinical outcome. Investigators expect to make MRS to become an integral part of a clinical cardiac MR protocol.
Genomic Response Analysis of Heart Failure Therapy in African Americans
Heart FailureThe response to therapy with a fixed dose combination of isosorbide dinitrate and hydralazine (FDC I/H) is enhanced in African Americans with heart failure and reduced ejection fraction (HFrEF) when compared to similar white cohorts. This study will seek to confirm the previous genetic sub-study from AHeFT which suggested a functional polymorphism of guanine nucleotide binding protein beta polypeptide 3 subunit (GNB3), C825T in exon 10, influences the therapeutic efficacy of FDC I/H. This study will initiate treatment with FDC I/H in 500 self designated African American subjects with systolic heart failure. They will be followed for up to two years on therapy. Clinical outcomes (survival, heart failure hospitalizations, and change in quality of life) on FDC I/H will be compared by GNB3 genotype subset. The hypothesis to be confirmed is that subjects homozygous for the T allele (those with the GNB3 TT genotype which is present in approximately 50% of black subjects) demonstrate enhanced therapeutic benefit from FDC I/H.
