Filter by:Sleep disordered breathing is very common in patients with chronic heart failure with reported prevalence rates of 50-75%. Adaptive Servo-Ventilation (ASV) can be used to treat sleep apnea in these patients. This is an observational study to document changes in respiratory parameters in HF patients using ASV for a period of 12 months.
Heart failure is a serious and common disease. HF is marked by a high rate of preventable hospitalizations through proper care. As such, it is a key target for telemedicine programs. However, currently published data are inconclusive. Investigators propose a multicenter randomized study of innovative telemedicine involving the usual patient monitoring daily weight monitoring, clinical signs and in one of three groups in our study of BNP testing in the patient's home all associated with a regular education reinforcement. The objective is to identify early cardiac decompensation to allow to treat ambulatory and thus prevent the occurrence of more serious events such as death or rehospitalization.
Evaluate pro-BNP levels, oxygen consumption, functional class, and quality of life in patients with chronic heart failure after participating in an exercise program and compare them baseline and 2 months, with another group who underwent an educational program.
Targeted population: Patients with heart failure causing hospitalization during the last twelve months. Hypothesis: The number of all cause deaths and hospitalizations will be smaller for the Telecardiology group than for the reference group (standard follow-up care). An 18 months period of observation is required. Main goal: To compare the rate of all cause deaths and hospitalizations of patients with heart failure between the Telecardiology group and the reference group after 18 months of monitoring.
The 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.
This 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.
Continuous-flow (CF) left ventricular assist devices (LVADs) are an important tool in the treatment of end-stage heart failure, affording patients significantly improved quantity and quality of life. In recent years, tens of thousands of LVADs have been implanted worldwide, with nearly 1,000 at the Texas Heart Institute (THI). Despite the benefits from LVAD therapy, one major weakness is the high frequency of late strokes, reported up to 19%. CF LVADs minimize or remove the pulsatility within the blood system, introducing a new and incompletely understood physiology. Increased sympathetic ("fight or flight" nervous system) tone secondary to lack of pulse in the blood system can cause high blood pressure, with subsequent hemorrhaging strokes (bleeding into the brain) are one possible explanation for this high adverse event rate in CF LVAD patients. A simple intervention to decrease the increased sympathetic tone is called "ischemic conditioning"; a sphygmomanometer (blood pressure cuff) is placed on the patient's arm to compress a major artery (ischemia) with subsequent release of the cuff (reperfusion) for set periods of time. This has been shown to reduce blood pressure and major adverse cardiovascular events in other patient populations. We plan to conduct a trial to evaluate this intervention, ischemic conditioning, in patients with CF LVADs. We hypothesize that IC will cause a reduction in blood pressure and strokes in this patient population.
The primary objective of this study is to determine whether transendocardial delivery of allogeneic human bone marrow-derived mesenchymal precursor cells (MPCs [rexlemestrocel-L]) is effective in the treatment of chronic heart failure (HF) due to left ventricular (LV) systolic dysfunction.
The purpose of this study is to describe insulin resistance in a general chronic heart failure population, in combination with muscle strength, body composition and cardiac function. It is assumed that insulin resistance is increased in CHF patient, and that this is related to decreased muscle strength and decreased lean tissue mass.
The purpose of this study is to investigate the effects of a combined training programme on insulin resistance, exercise tolerance, muscle strength, body composition and cardiac function in chronic heart failure patients. It is assumed that the above mentioned clinical parameters will improve due to physical exercise.
