Filter by:Aortix is a circulatory support device for chronic heart failure patients on medical management who have been hospitalized for acute decompensated heart failure (ADHF) and are resistant to diuretic therapy. Eligible ADHF patients with diuretic resistance (irrespective of ejection fraction) will be enrolled and randomized 1:1 to either the Aortix system or standard of care medical management.
The goal of this prospective cohort study is to investigate cardiac comorbidity in a random sample of approximately 1200 patients from a population of outpatients with rheumatoid arthritis and axial spondyloarthritis referred to collectively as inflammatory arthritis (IA). The main questions it aims to answer are: - Using conventional echocardiography, the investigators aim to determine the prevalence of overt and asymptomatic cardiac dysfunction in a large random sample of outpatients with IA. Cardiac dysfunction will be evaluated by echocardiography and cardiac biomarkers (NT-pro-BNP, hs-TNT and hs-CRP). - In patients without known heart disease: Using 2, 5 and 10 year follow-up, the investigators aim to examine if advanced echocardiography can be used to detect early signs of heart disease by investigating the clinical significance of adding deformation measures - alone and in combination with selected biomarkers - to conventional risk factors in the cardiac risk assessment of patients with IA Participants will undergo an echocardiographic examination in combination with a general health assessment including obtainment of cardiac biomarkers and a electrocardiogram. Using advanced echocardiography - Tissue Doppler Imaging, 2- dimensional speckle tracking echocardiography, 3D-echocardiography and 3-dimensional speckle tracking echocardiography - the investigators also aim to compare myocardial deformation parameters of patients with IA to a gender and age matched control group without IA from the Copenhagen City Heart Study.
The goal of this observational study is to learn about left atrial reservoir strain in patients with heart failure with preserved ejection fraction. The main questions it aims to answer are: - Usefullness of LARS as a predictor of high HFA-PEFF diagnostic algorithm scores (≥5) - The relative importance of LARS in variables including each component of HFA-PEFF and traditional cardiovascular risk factors.
Background: Heart failure is described by a lack of confirmed efficient therapies and exercise intolerance. Physical activity is related to a lower risk of adverse cardiovascular consequences, involving heart failure. The purpose of the study: determine the effect of different types of aerobic training on peak VO2 and ejection fraction in diastolic heart failure patients. Subject and methods: Forty eligible male patients with diastolic heart failure, aged between 50 - 60 years old, participated in this study. They were selected from an outpatient clinic of general Zagazig hospital and were assigned into 2 equal groups in numbers. The first group (A) received aerobic exercise for the upper limb in form of arm ergometer exercises, while the second group (B) received aerobic exercise for the lower limb in form of cycling. Training duration for both groups was 3 sessions/week for 12 weeks. Peak VO2, and ejection fraction of both groups were measured and compared pre and post-treatment. Results: There was no significant difference in the ejection fraction between groups post-treatment. There was a significant increase in the peak VO2 of group B compared with that of group A post-treatment. Conclusion: there is no effect of different types of aerobic training on ejection fraction and peak VO2 for diastolic heart failure patients, but lower limb exercise is more effective than upper limb exercise in improvement of peak VO2 for diastolic heart failure patients.
Investigators will determine whether N-of-1 trials, as a pragmatic, patient-centered approach to medication optimization that can overcome key barriers of deprescribing, can lead to increased subject confidence regarding the decision to continue or discontinue beta-blockers in older adults with Heart Failure with Preserved Ejection Fraction (HFpEF).
Recent studies have shown that transthyretin amyloidosis (ATTR) can sometimes cause a type of heart failure where the pumping function of the heart is normal, also known as Heart Failure with Preserved Ejection Fraction (HFpEF) or diastolic heart failure. In this single center diagnostic study, we will evaluate for ATTR in patients with HFpEF in order to to determine how frequently this occurs and how we can predict which heart failure patients may have TTR amyloidosis. Our goal is to identify amyloidosis in heart failure patients earlier so that they can start treatment.
Heart failure (HF) with a left ventricular ejection fraction (LVEF) >0.40 is a large medical problem, for which no drug or device has a recommendation in current HF guidelines. The prevalence of mortality and HF hospitalizations in HF with LVEF >0.40 is high, but the identification of predictors for increased risk of mortality and HF hospitalizations in this patient category remains difficult. The hypothesis of this study is that the risk of all-cause mortality and HF hospitalizations can be measured by clinical factors, imaging parameters and circulating biomarkers, and that these factors can be used in a risk profile
Heart failure (HF) is a syndrome, resulting from structural or functional impairment of ventricular filling or ejection of blood. Effective HF management depends on accurate and rapid diagnosis requiring assessment of symptoms and physical signs in combination with advanced and expensive imaging tools. However, several challenges arise from the traditional symptom-based diagnosis because co-morbidities of HF have similar presentations. This implies the need for a deeper knowledge of mechanistic links among genetic and epigenetic events governing the pathophysiology of HF leading to a novel molecular-based system to differentiate HF phenotypes. Now, it is emerging that the pathophysiology of HFpEF and HFrEF is different, it provides an opportunity to identify biomarker candidates that could aid in HF diagnosis and stratification between these two forms of the disease. The aim of PRESMET project is to perform liquid biopsy strategies to identify novel putative non-invasive epigenetic-sensitive biomarkers that could be used either alone or in combination with established diagnostic tests, such as natriuretic peptide, to help differentiate HFpEF from HFrEF. The Investigators will perform DNA methylation analysis on CD4+ T cells isolated from patients versus controls. Remarkably, big data generated from NGS tools will be analyzed by advanced network-oriented algorithms. Our results may provide a useful clinical roadmap in order to improve precision medicine and personalized therapy of HF.
Multicenter, Prospective, Randomized, Sham Controlled, Double Blinded Clinical Trial, with; 1:1 randomization
Our local IRB approved clinical studies seeking proof of principle for the hypothesis that SFN can be safely administered to humans at doses sufficient to protect age-associated cardiac dysfunctions. Beneficial effects of SFN-therapy will be assessed by Pre- and post-intervention echocardiography, and exercise endurance at 0 and 24 weeks. Peripheral blood cells from treated and control subjects will be compared for mitochondrial respiratory function, oxidative damage, pro-inflammatory cytokines, and expression of antioxidant & anti-electrophile genes.
