Filter by:This study is trying to find out how best to improve common measures of health and survival in those diagnosed with heart failure with preserved ejection fraction (HFpEF) through the implementation of 4 weeks of an exercise training program consisting of high intensity interval training, dietary approaches to stop hypertension (DASH diet), or a combination of the two. Currently there are not established guidelines that have been shown to improve clinical end points in those with this HFpEF.
Heart failure (HF) is among the most common causes of death in patients with type 2 diabetes (T2D). Ketones, 3-hydroxybutyrate (3-OHB), have shown to have beneficial hemodynamics effect in patients with hearth failure with reduced ejection fraction. However, this have never been investigated in patients with heart failure with preserved ejection fraction (HFpEF). In this study we would like to investigate the effect of 14 days modulation of circulating ketone body levels on cardiac function and exercise capacity in patients with HFpEF and T2D.
An application (app) called the activity coach will be tested to see if it can increase physical activity and decrease sedentary behaviuor, as well as increase quality of life and lead to personal goal attainment in physically inactive heart failure (HF) patients. This pilot randomized controlled trial (RCT) will test the study design and recruitment process, as well as outcomes for a future efficacy RCT. HF-patients equipped with the mHealth-tool Optilogg will be screened for physical inactivity and then recruited and randomized to either have the activity coach app added to their Optilogg or remain with the standard Optilogg. The study will go on for 12 weeks. Weeks 1 and 12 physical activity using an accelerometer will be recorded, as well as health-related quality of life. At the start of the study the patients will list goals relating to physical activity which the wish to attain, and the level of attainment will be evaluated at the end of the study. The activity coach educated the patient about physical activity, offers means of manually tracking physical activity, and provides trends of registered activity. Furthermore, it provides weekly summaries of registered physical activity and provides means of setting goals for the following week.
Rationale. Chronic obstructive pulmonary disease (COPD) and heart failure (HF) coexist in approximately one third of patients presenting with one of these conditions. From a clinical standpoint, impaired tissue oxygen (O2) delivery stands as a common pathological mechanism of these cardiorespiratory diseases. Recent evidence suggest that muscle and cerebral blood flow and oxygenation are further impaired during exercise in patients with COPD-HF overlap compared to isolated diseases. However, it remains unknown whether impaired O2 delivery is associated with exaggerated manifestations of peripheral and central fatigue in COPD-HF overlap. In addition, improving cardiopulmonary interactions through non invasive positive pressure ventilation or through the addition of a hyperoxic gas mixture during exercise have been associated with enhanced cerebral and muscle O2 delivery and oxygenation in patients with COPD or HF. It is, therefore, conceivable that improved O2 delivery to these structures have beneficial influence on exercise capacity in patients with COPD-HF overlap due to less peripheral and central fatigue. Aims. To investigate the influence of impaired O2 delivery during exercise, and its alleviation with different interventions (non invasive positive pressure ventilation ± hyperoxia), on neuromuscular fatigue in patients with COPD-HF.
To explore medication adherence in patients who were hospitalised due to heart failure.
Ketone bodies are produced in the liver at high levels of fatty acids, and act as an important source of energy for the brain and heart during fasting. The energy production from ketone metabolism is less oxygen-demanding than both glucose and fatty acid metabolism, and ketone substances can therefore be a very energy-efficient substrate for the heart. Insulin-resistant people as well as people with heart disease have difficulty burning glucose in the heart due to the insulin resistant condition and are therefore dependent on other energy sources such as free fatty acids and ketones. Because ketones are oxygen-sparing compared to fatty acids, interventions that increase the level of ketone bodies can potentially reduce the heart's need for oxygen in patients with narrowed coronary arteries. PET/CT is a functional and non-invasive imaging modality and suitable for tracking the fate of metabolites non-invasively, as most substrates or metabolites can be labeled by a PET isotope. The purpose of this experiment is therefore to validate a new ketone tracer called 3-[11C]-OHB. Implementation of the 3-[11C]-OHB tracer will in future allow the investigators to more directly estimate the impact of different levels of ketone bodies on organ functions by measuring tissue-specific ketone uptake, both after intravenous and oral administration.
Study Description: Background: Well-known fact that the number of cardiovascular diseases is on the rise during influenza epidemic. It is conceivable that influenza may precipitate plaque rupture, increase cytokines with central roles in plaque destabilization and trigger the coagulation cascade. A number of studies have shown that the risk of cardiovascular complications (ACS, stroke, CHF decompensation, cardiac arrhythmias) seem to be reduced following influenza vaccination. The Influenza Vaccination After Myocardial Infarction study data published in September 2021 have demonstrated a significant decrease of mortality (by 40%) during 1 year of follow-up in patients with myocardial infarction (MI) who has been vaccinated during the first 72 hours. Objective: the objective is to find out whether influenza vaccination protects against cardiovascular events and death in ACS & CHF patients vaccinated during hospitalization Methods: Population: 400 patients aged 65 and older with acute coronary syndrome are randomized 1:1 and followed up via telephone calls and registries (AIS "Mortality"). Patients will be included in the study in cardiology departments № 1, 2, 3, 5, 6 of the State Budgetary Healthcare Institution "Samara Regional Clinical Cardiology Dispensary named after V.P. Polyakov" Intervention: Influenza vaccination. Control: group of unvaccinated patients. Planned study period is 1 year.
In 2009, OFICA 1 provided a snapshot of the management of acute heart failure in France. Over the past 10 years, practitioners have observed a change in the profiles of hospitalized patients and it is necessary to specify the evolution of these characteristics, especially since the recommendations concerning management have changed significantly; this is the objective of this observatory. Like patients suffering from chronic diseases such as diabetes or asthma, heart failure patients are therefore at the center of their management. Compliance is improved when patients have understood the reason for the prescription. Ideally, compliance should not be achieved by respecting externally imposed norms, but rather by respecting norms that are understood, adapted, personalized and accepted. A self-questionnaire will thus be given to patients on the day of inclusion in the study. In heart failure patients with an average age of 80 years, systematic screening for cognitive disorders using a simple test recommended by the French National Authority for Health (Haute Autorité de Santé), the codex test, will make it possible to offer more appropriate care if necessary (geriatric or neurology consultation). Finally, follow-up at 3 months and at 1 and 2 years will be carried out by matching with data from the National Health Data System (SNDS)
Indoor air pollution and fine mode particulate matter with an aerodynamic diameter smaller than 2.5 micrometers (PM2.5) is a major contributor to global morbidity and mortality, particularly due to cardiovascular disease. This project aims to demonstrate the efficacy, feasibility and effectiveness of portable air filters in improving indoor PM2.5 levels and improving functional capacity of heart failure patients with reduced ejection fraction in India. The findings from the project will add to existing knowledge of innovative and scalable strategies to improve environmental and cardiovascular health worldwide. The overall objective of this study is to demonstrate the efficacy, feasibility, and effectiveness of portable air filters in improving indoor PM2.5 levels and improving functional capacity of heart failure patients with reduced ejection fraction in India.
The ContraBand™ device is intended for treatment of heart failure patients who remain symptomatic despite the use of optimally tolerated guideline directed medical therapy. ContraBand™ is a transcatheter constriction device which is implanted in the left and right branch pulmonary arteries, causing a local reduction in the internal diameters of these arteries, and resulting in an elevation in systolic right ventricular pressure. This may result in repositioning the interventricular septum to a more normal anatomical position, and supporting it with a "counter-pressure" during systole of the left ventricle. This study is a first-in-human, early feasibility, multi center, prospective, interventional, open-label, single-arm study.
