Filter by:Heart failure (HF) is a common disease, which impacts on other organs. Despite an ongoing progress in knowledge about HF, there are still some uncharted aspects of impact of HF on respiratory system. The aim of the study is to determine whether there are any differences in pulmonary changes assessed in chest CT, chest ultrasound or in pulmonary function tests between patients with HF with decreased (≤40%; HFrEF) and preserved (≥50%; HFpEF) ejection fraction. Eighty four patients diagnosed with HF will be included (42 with HFrEF and 42 with HFpEF) and the following tests will be performed : 1. echocardiography 2. chest X-ray and CT 3. assessment of lung hydration in ultrasound 4. spirometry, plethysmography, diffusion capacity for carbon monoxide (DLCO) 5. arterial blood gas analysis 6. peripheral blood collection In patients with abnormal, suspected changes in the lungs diagnosed in the chest CT bronchoscopy and endobronchial ultrasound (EBUS) will be offered. The primary outcome will be difference in frequency of chest CT abnormalities (ground-glass opacities or interlobular septal thickening or pleural effusion or mediastinal lymphadenopathy) between patients with HFrEF and HFpEF The secondary outcomes will be: 1. difference in pulmonary function test results (FEV1, FVC, TLC, RV, DLCO) 2. differences in arterial pO2 and pCO2 3. differences in B- line scores in ultrasound 4. differences in concentration of blood biomarkers (troponin, CRP, NTproBNP, IL-6, TNF-α, sST2, Gal-3, GDF-15) The results of the study will allow to .better understand the pathomechanisms of the occurrence of lesions in lungs secondary to HF. Thus, it may anable to reduce unnecessary diagnostics in patients with HF in the future.
Heart failure is a general disease affecting many organs and regulatory systems with a prevalence of 10% after 75 years of age, leading to significant hospitalization in the elderly. This generates a significant cost for our health system. The management of patients over 75 years of age in acute heart failure requires special monitoring of diuresis and weight. However, it is sometimes difficult to collect urine from incontinent elderly patients (not catheterized, habitually wearing protection) under intravenous diuretics. The evaluation of a non-invasive technique of urine collection for the adaptation of diuretic treatment in the incontinent patient with heart failure over 75 years of age in the acute phase seems to us to be interesting to conduct.
The proposed intervention will be administration of empagliflozin at a standard dose of 10 mg daily for a period of 12 months. Patients with diagnosed diabetes will be excluded from the study. Patients (n = 250) will be randomized in a double-blind fashion to empagliflozin or placebo group. The primary endpoint of the study will be the change in peak oxygen uptake (VO2 max) measured in a cardiopulmonary exercise test. VO2max is an objective indicator of physical performance and will be evaluated before and after empagliflozin or placebo treatment.
Guidelines-directed medical therapy has improved dramatically outcomes in heart failure with reduced ejection fraction (HFrEF) patients. Beta-blockers have the most beneficial effects on all caused mortality and rehospitalization on HFrEF, but unfortunately, since the discovery of beta-blocker therapy in HFrEF, there was no change in the way of titration, start low go slow, which resulted in difficulties in reaching optimal doses for some patients.
Overarching aim of project Performance and image enhancing drugs (PIEDs) are pharmacological agents acquired illicitly to improve physical strength and endurance as well as to obtain a leaner and more muscular appearance. Androgenic anabolic steroids (AAS) are the most frequently used PIED and include testosterone and its synthetic derivatives. However, PIEDs also include other hormones, e.g. growth hormone (GH), insulin-like growth factor I (IGF-I), glucocorticoids, insulin and thyroxin. Originally, the use of PIEDs was predominately restricted to elite athletes. However, today most users of PIEDs are recreational athletes. In USA, the prevalence of recreational PIED users (three million) exceeds the prevalence of type 1 diabetes. This appears to be the same in Denmark, where the estimated prevalence of recreational users of PIEDs is 44,000, compared to approximately 30,000 patients with type 1 diabetes. The access to AAS is easy due to the unregulated and illicit sale on the internet. Furthermore, PIED use is common in the young population with possible detrimental effects on future health and well-being. PIEDs are linked to premature death and a wide spectrum of somatic and psychological disorders. However, clinical data on the use of PIEDs is currently limited. Randomized trials of PIEDs are unethical as this would require administration of potentially harmful supra-physiological doses of hormones and this is the rationale behind our proposal to perform an observational study. With this project the investigators propose to a) Perform a cross-sectional nationwide study of current and former users of PIEDs (N=1200), focusing on AAS. In particular, the investigators will pay attention to: 1. Preclinical cardiovascular disease 2. Psychological well-being, aggression and quality of life 3. Biomarkers of ageing 4. Body composition and muscle strength b) Establish a nationwide biobank containing blood, urine and hair samples from current and former users of PIEDs.
Patients who have a heart attack are at high risk for future development of heart failure ('weakening of the heart'). The researchers believe that the reaction of the heart muscle to injury (inflammation) during a heart attack may be contributing to the risk of heart failure. The current study will test the ability of an anti-inflammatory medicine (anakinra) to block the inflammation in the body during and after a heart attack.
This study is a prospective, multi-center, open label, randomized clinical trial conducted in the republic of Korea. The objective of this study is to evaluate the efficacy and safety of the treatment using home bioelectrical impedance analysis (BIA) and linked application system in patients with heart failure (HF).
Observational multicenter registry of cohorts with follow-up. Patients with heart failure, age ≥ 18 years, with clinical suspicion of cardiac amyloidosis and any LVEF value, treated in the field of Internal Medicine. Initially, a duration of two years was established to recruit at least 150 patients in the group with AC, and a follow-up of two years. Upon completion of the two years of follow-up, the continuity or completion of the registry will be assessed.
The objective of this observational study is to assess clinical benefits of innovative features (e.g. Bluetooth technology and smartphone patient applications) in a patient population that is implanted with standard indication for implantable cardiac defibrillator.
This is a prospective pilot study to evaluate changes before and 4 weeks after beta-blocker withdrawal in 30 HFpEF patients.
