Filter by:GSK2798745 is being developed as a novel therapeutic intervention for the treatment of pulmonary edema associated with heart failure (HF) and is currently under investigation in the form of a compounded capsule. This is an open-label, randomized, single-dose, crossover study with the purpose to determine the pharmacokinetics (PK) of three 2.4 milligrams (mg) tablet formulations of GSK2798745 in 12 healthy subjects. The three formulations developed for this study will be micronized GSK2798745 active pharmaceutical ingredient (API) (Tablet A), micronized GSK2798745 API with sodium lauryl sulfate (SLS) and hypromellose (Tablet B), milled GSK2798745 API with SLS and hypermellose (Tablet C), and Tablet D, which will be either A/B/C based on interim PK analysis of data from the first three treatment periods. Following a 30-day screening period, subjects will be randomized to one of the 6 treatment sequences: Treatment sequence 1: ABCD, 2=CABD, 3=ACBD, 4=BACD, 5=BCAD, 6=CBAD over three 4-day treatment periods. For treatment period 4, the best formulation based on the interim analysis data from the three treatment periods will be evaluated under fed conditions. Each treatment period will be separated by a minimum of 7 (+14)-day washout period. The total duration of participation in the study will be approximately 11 weeks including the follow-up visit.
Non-adherence to the heart failure (HF) plan of care after hospital discharge has been associated with clinical outcomes, including the combined endpoint of all-cause mortality and rehospitalization for decompensated HF. Patients and informal caregivers receive education materials but may not act due to multiple factors. A recorded message that could be repeatedly played by patients and caregivers might increase adherence to post-discharge self-care behaviors and early follow-up appointments, and have clinical benefits related to a reduction in all-cause mortality and rehospitalization. The purposes of this randomized, controlled study are to examine the effects of use of a novel MyROAD (Recordable On-Demand Audio Discharge) card, given to patients at discharge. The aims of this single-blind, placebo-controlled study are to examine the effects of recorded messages that can be replayed post discharge (delivered via the MyROAD card) on multiple subjective and objective clinical outcomes.
Heart failure with preserved ejection fraction or HFpEF, represents nearly 50% of all heart failure cases and is particularly common in the elderly. The disease has no current treatment options. Symptoms typically occur during exertion or exercise and is likely the result of increased cardiac and pulmonary congestion as a result of impaired diastolic function. Istaroxime is a novel activator of SERCA2a, an important regulator of calcium uptake within the myocyte. We will test the hypothesis that Istaroxime will improve diastolic function during exercise in HFpEF patients which in turn will reduce cardiac and pulmonary congestion.
Chronic insomnia may contribute to the development and exacerbation of heart failure (HF), incident mortality and contributes to common and disabling symptoms (fatigue, dyspnea, anxiety, depression, excessive daytime sleepiness, and pain) and decrements in objective and subjective functional performance. The purposes of the study are to evaluate the sustained effects of CBT-I on insomnia severity, sleep characteristics, daytime symptoms, and functional performance over twelve months among patients who have stable chronic HF and chronic insomnia. The effects of the treatment on outcomes of HF (hospitalization, death) and costs of the treatment will also be examined. A total of 200 participants will be randomized to 4 bi-weekly group sessions of cognitive behavioral therapy for CBT-I (behavioral was to improve insomnia and sleep) or HF self-management education. Participants will complete wrist actigraph (wrist-watch like accelerometer) measures of sleep, diaries, reaction time, and 6 minute walk test distance. They will also complete self-report measures of insomnia, sleep, symptoms, and functional performance. In addition the effects on symptoms and function over a period of one year.
Transient receptor potential vanilloid 4 (TRPV4) channel blockade may be promising in the treatment of pulmonary oedema and dyspnoea in heart failure (HF) and acute decompensated heart failure (ADHF) patients by re-establishing the alveolar septal barrier. Dynamic contrast enhanced (DCE) Magnetic Resonance Imaging (MRI) is an established technique for assessing changes in vascular permeability and interstitial water volume. The aim of this study is to establish the potential utility of DCE-MRI as a novel endpoint for dose ranging and proof of mechanism studies of TRPV4 blockers. The DCE-MRI markers of vascular permeability and pulmonary oedema will be measured in subjects with HF (group 2) and healthy volunteers (HV) (group 1) at rest to determine if there is a difference between the two populations. Apart from this, exercise induced changes relative to rest in interstitial volume and exchange rate will be evaluated in both HV and subjects with HF. Additionally, the capability of DCE-MRI to detect changes in interstitial lung fluid in patients with acute decompensated heart failure (ADHF) (group 3) will be investigated. DCE-MRI markers of pulmonary oedema will be assessed when patients are initially hospitalized with ADHF and subsequently after receiving standard of care treatment to determine whether differences can be detected by this methodology.This study will enrol a sufficient number of subjects to have at least 24 subjects in Group 1 and 2 (group 1:12 HV and group 2: 12 subjects with HF) and atleast 5 subjects in Group 3. For each subject, the MRI data must be of sufficient quality to enable DCE-MRI modelling from 2 Sessions. For group 1 and 2, the subjects will have screening visit and 3 MRI sessions. For the first scanning session, subjects will undergo the baseline procedure. The second imaging session will occur approximately one week later to measure within subject variability. A third imaging session (which will be conducted in 2 visits) will incorporate a bicycle exercise challenge prior to the MRI scan, and this third scan will be performed approximately one to three days after the second imaging session. For group 3: Screening will occur during hospitalization for eligibility. Session 1of MRI will be conducted while the subject is still hospitalized. Session 2 will be conducted within 4 weeks of the first scan, when the signs of pulmonary oedema are considered to be resolved. If a subject's pulmonary oedema has not resolved at Session 2, then the subject will be not be scanned by MRI at Session 2 and will be brought back for Session 3 up to 4 weeks after Session 2 for their second MRI.
The purpose of this study is to test whether a culturally sensitive self-management (SM) intervention, compared to an education only control, will reduce all-cause hospital days in patients with mild to moderate heart failure and household income less than $30,000 per year.
Prospective, follow-up registry of heart failure patients with or without sleep-disordered breathing (SDB). To test the hypothesis that treatment of nocturnal central sleep apnea with Cheyne-Stokes respiration by adaptive servoventilation (ASV) improves symptoms, cardiac performance and event-free survival.
The main aim of this study is to conduct a randomized control trial to compare MobileMedMinder, a mobile phone based medication reminder software product, with currently accepted and empirically supported methods for increasing medication compliance through reminders and tracking.
BACKGROUND: Exercise intolerance is the primary symptom in older patients with heart failure and preserved ejection fraction (HFPEF), however little is known regarding its mechanisms and therapy. METHODS: 71 elderly stable, compensated HFPEF patients (age 70+1 years; 80% women) with controlled blood pressure were randomized into a 12 month follow-up (FU) double-blind trial of enalapril 20 mg per day (E) vs. placebo (P). Assessments included: peak exercise oxygen consumption (VO2); six-minute walk test; Minnesota Living with HF Questionnaire (MLHF); MRI; Doppler-echocardiography; and vascular ultrasound.
The purpose of this study is to survey the guideline compliance of the cardiologists in the treatment of systolic heart failure in Korea
